+description: Use when running, deploying, submitting, attaching to, or retrieving results from a single AIPerf benchmark on a Kubernetes cluster with the aiperf kube CLI (AIPerfJob CR, operator mode or direct mode).
+---
+
+# Running an AIPerf Benchmark on Kubernetes
+
+Hub skill for the `aiperf kube` lifecycle. One `AIPerfJob` = one benchmark = one
+controller pod + N worker pods, orchestrated by the in-cluster operator.
+
+**Related skills:** `aiperf-kube-setup` (cluster/operator install),
+`aiperf-kube-triage` (a run is stuck or failed), `aiperf-kube-sweep`
+(multi-variation runs).
+
+## Lifecycle
+
+| Stage | Command | Touches cluster |
+|---|---|---|
+| 1. Scaffold config | `aiperf kube init -t <template> -o bench.yaml` | no |
+| 2. Offline check | `aiperf kube validate bench.yaml` | no |
+| 3. Cluster check | `aiperf kube preflight -i <image> -e <url> -w <n>` | yes |
+| 4. Deploy | `aiperf kube profile --config bench.yaml --image <image>` | yes |
+| 5. Watch | `aiperf kube attach` / `aiperf kube list --watch` | yes |
+| 6. Collect | `aiperf kube results` | yes |
+| 7. Clean up | `aiperf kube delete <name> --force` | yes |
+
+Full lifecycle narrative, phase table, exit codes, and per-command flag
+reference: `references/lifecycle.md` (bundled with this skill).
+
+## Minimum viable run
+
+```bash
+aiperf kube preflight -i aiperf:latest -e http://server:8000 -w 1
+aiperf kube profile \
+    --model Qwen/Qwen3-0.6B \
+    --url http://server:8000 \
+    --image aiperf:latest \
+    --total-workers 8 \
+    --detach
+aiperf kube attach          # live progress
+aiperf kube list            # phase == Completed?
+aiperf kube results         # -> ./artifacts/<name>/
+```
+
+`-w` on `preflight` counts worker **pods**; `--total-workers` on `profile`
+counts worker **processes**, packed `runtime.workersPerPod` (default 10) per
+pod. `--total-workers 8` is one pod, so preflight it with `-w 1`; for 8 worker
+pods use `--total-workers 80 -w 8`. A total that is neither <= workersPerPod nor
+a multiple of it is rejected rather than silently collapsed onto one pod.
+
+
+The benchmark namespace comes from `-n`/`--namespace`, or your kubeconfig
+context when the flag is omitted; there is no fallback. Operator namespace
+defaults to `aiperf-system` (auto-detected by cluster-wide pod-label search).
+
+## Rules that bite
+
+- **Foreground `profile` in operator mode hard-times-out at 600 s.** Anything
+  longer than ~10 minutes MUST use `--detach` plus `aiperf kube attach`.
+  Ctrl+C or the timeout does not stop the cluster-side run. The limit is
+  `AIPERF_K8S_WATCH_DEFAULT_TIMEOUT_SECONDS` (600, max 86400) if you would
+  rather raise it than detach.
+- **Non-TTY stdout auto-detaches.** CI and piped invocations never block; do not
+  write scripts that assume `profile` waits.
+- **`--dry-run` never contacts the cluster**, so the mode it prints is *assumed*,
+  not detected, and the CR is printed *before* validation. Pass `--no-operator`
+  to preview direct mode. Use `aiperf kube validate` for a real verdict.
+- **`~/.aiperf/last_kube_benchmark.json` is per-user, not per-context.** Every
+  command that defaults its target reads it. When working across clusters or
+  namespaces in one shell, always pass the job id positionally plus `-n` and
+  `--kube-context`.
+- **`kubectl delete` leaves that file stale**; `aiperf kube delete` clears it.
+- **Results come from the operator PVC by default.** `--from-pods` is required
+  for direct-mode runs, and on the default `--all` path the controller API is
+  the only tier — there is no `kubectl cp` fallback unless `--summary-only`.
+- **Cancel is not delete, but it is not a safe pause either.** `aiperf kube
+  cancel` patches `spec.cancel: true`; the CR survives, but the operator
+  deletes the JobSet and sets `phase=Cancelled` **without harvesting**, and
+  every completion path short-circuits once cancellation is requested. Results
+  survive only if a harvest already finished. Cancel an in-flight run and there
+  is nothing on the PVC and no pods left for `--from-pods` — download first,
+  cancel second.
+- **Ambiguous names are refused, not guessed.** When an `AIPerfJob` and an
+  `AIPerfSweep` share a name, destructive commands need `--kind job|sweep`.
+  The refusal prints an error and **still exits 0**, so a script that only
+  checks `$?` will believe it cancelled or deleted something.
+- **`cancel` and `delete` only know about CRs, and say nothing useful when
+  there isn't one.** Both resolve the target by looking up an `AIPerfJob` or `AIPerfSweep` CR by name; a
+  direct-mode (`--no-operator`) run has no `AIPerfJob`, so they print "No
+  AIPerfJob or AIPerfSweep named ..." and exit 0 while the JobSet keeps
+  running. Tear down direct-mode runs with `kubectl delete jobset <name>` (plus
+  its ConfigMap/Role/RoleBinding), not with `aiperf kube delete`.
+
+## Exit-code convention
+
+| Group | Commands | Exits non-zero when |
+|---|---|---|
+| Gating | `validate`, `preflight`, `results`, `results list-runs` | any failure, including partial download |
+| Addressing | `attach`, `logs`, `cancel`, `delete`, `shutdown`, `debug`, `list` | only `attach`/`logs`, only when the target does not exist (`list` also exits 1 on conflicting status filters). `cancel`/`delete` exit 0 even on not-found and on ambiguous-name refusal |
+
+Use `--ignore-not-found` on `attach`/`logs` in teardown scripts. A target that
+exists but has nothing to show exits 0 by design.
+
+## Operator mode vs direct mode
+
+Operator mode is chosen automatically when the `aiperfjobs.aiperf.nvidia.com`
+CRD is present. It owns JobSet/ConfigMap/RBAC lifecycle via ownerReferences and
+harvests results to a PVC on terminal phase (nothing is harvested mid-run).
+
+Direct mode (`--no-operator`, or CRD absent) creates the resources itself, has
+no CR and no PVC, and uses an 8-hour JobSet TTL (vs 5 minutes) so pods survive
+long enough for `aiperf kube results --from-pods`. Direct-mode details are in
+`references/lifecycle.md`.
+
+`--operator` skips the cluster-scoped CRD probe on its own — that is how
+namespace-scoped tenants submit without cluster-wide RBAC. Pair it with an
+explicit `--namespace`, since skipping the probe also skips operator
+discovery.
+
+## Common mistakes
+
+| Mistake | Consequence |
+|---|---|
+| Long run without `--detach` | `TimeoutError` at 600 s; run keeps going, you lose the stream |
+| `aiperf kube results` right after submit | Operator harvests only on terminal phase; wait for `Completed` |
+| Trusting `--dry-run` as validation | Unknown envelope keys print fine and reject on submit |
+| Omitting `-n` after switching clusters | Reads the other cluster's last-benchmark record |
+| Reusing a direct-mode name without deleting ConfigMap/Role/RoleBinding | Direct mode refuses to adopt existing resources |
+| `aiperf kube delete` on a direct-mode run | Prints not-found, exits 0, JobSet keeps burning cluster capacity |

+# `aiperf kube` Lifecycle Reference
+
+Terminal reference for the single-benchmark lifecycle: operator mode, direct
+mode, and the flag surface of every subcommand in the flow.
+
+Every cluster-touching command accepts `-n`/`--namespace` (unset -> the
+namespace your kubeconfig context sets; an error if it sets none),
+`--kubeconfig` (`~/.kube/config` or `$KUBECONFIG`), and
+`--kube-context` (current context). The operator namespace defaults to
+`aiperf-system`, auto-detected by cluster-wide pod-label search. Commands that
+default their target read `~/.aiperf/last_kube_benchmark.json`.
+
+## Operator-mode workflow
+
+```bash
+# 1-2. Scaffold + validate offline (no cluster contacted)
+aiperf kube init -t goodput_slo \
+    --model Qwen/Qwen3-0.6B --url http://server:8000 -o bench.yaml
+aiperf kube validate --strict bench.yaml
+
+# 3. Cluster readiness: connectivity, API versions, RBAC, node capacity,
+#    image pull-ability, endpoint reachability
+aiperf kube preflight -i aiperf:latest -e http://server:8000 -w 1
+
+# 4. Submit one AIPerfJob CR; the operator owns the JobSet, ConfigMap,
+#    Role and RoleBinding via ownerReferences
+aiperf kube profile --config bench.yaml --image aiperf:latest \
+    --total-workers 8 --detach
+
+# 5. Watch
+aiperf kube attach                 # WebSocket progress via port-forward
+aiperf kube list --watch           # CR phase table, refreshed
+aiperf kube logs -f                # controller/worker pod logs
+
+# 6. Collect once phase == Completed (harvest happens only on terminal phase)
+aiperf kube results                # -> ./artifacts/<name>/
+
+# 7. Retire / remove
+aiperf kube shutdown               # let the finished controller pod exit
+aiperf kube delete <name> --force  # CR + GC'd children; PVC results survive
+```
+
+`-w` on `preflight` counts worker **pods**; `--total-workers` on `profile`
+counts worker **processes**, packed `runtime.workersPerPod` (default 10) per
+pod. `--total-workers 8` is one pod, so preflight it with `-w 1`; for 8 worker
+pods use `--total-workers 80 -w 8`. A total that is neither <= workersPerPod nor
+a multiple of it is rejected rather than silently collapsed onto one pod.
+
+
+Operator mode is chosen automatically when the `aiperfjobs.aiperf.nvidia.com`
+CRD is present. `--operator` forces it while skipping the cluster-scoped CRD
+probe — how a namespace-scoped tenant submits without cluster-wide RBAC; pair
+it with an explicit `--namespace`, since skipping the probe also skips operator
+discovery. On a terminal phase the operator copies results to a shared PVC (on
+failure it salvages partial checkpoints); nothing is harvested mid-run.
+
+### `--dry-run` fidelity
+
+`--dry-run` never contacts the cluster, so the mode it prints is assumed, not
+detected, and the CR is printed *before* the spec is schema-validated.
+
+With `--operator` or `--no-operator` the flagged mode always wins and no probe
+happens. With neither flag: a real run probes the CRD and falls back to direct
+when it is absent, while `--dry-run` skips the probe and always renders the
+`AIPerfJob` CR (a stderr note says so).
+
+A hand-authored CR passed with `--config` prints snake_case keys as authored
+(`ttl_seconds_after_finished`) but submits camelCase, and unknown envelope keys
+print fine yet exit 1 on real submission. Use `validate` for a real verdict.
+
+## Direct mode
+
+Triggered by `--no-operator`, or automatically when the `AIPerfJob` CRD is
+absent. The CLI creates `Role`, `RoleBinding`, `ConfigMap`, `JobSet` — plus a
+`Namespace` when `--namespace` is omitted — itself, in that creation order.
+
+It keeps the same image, JobSet topology (one controller pod + N worker pods),
+run-config ConfigMap, per-namespace Role/RoleBinding (read/watch on pods, pod
+logs, jobs, ConfigMaps, Services, Endpoints, Events, plus `patch` on JobSets
+and on `aiperfjobs`/`aiperfjobs/status`; no create/update/delete verb), and live `attach` stream. An `AIPerfJob` YAML
+still works as input — its JobSet-compatible deployment fields are projected
+into the raw manifests with operator-mode override precedence. It is *not* the
+operator Deployment, a CR, a PVC, a dashboard, or cross-job analytics.
+
+### Trade-off matrix
+
+| Feature | Operator mode | Direct mode |
+|---|---|---|
+| Submission object | `AIPerfJob` CR | `Role` + `RoleBinding` + `ConfigMap` + `JobSet` (+ `Namespace` if auto-created) |
+| Status surface | `AIPerfJob.status.phase` | `JobSet` + pod status only |
+| Web dashboard (operator results server, port 8081) | yes | no |
+| Results persistence | operator PVC (durable) | controller pod's ephemeral volume only |
+| TTL after finish | `ttlSecondsAfterFinished` 300 s | 28800 s (8 h), so pods outlive the run for retrieval |
+| Admission / preflight | operator-side before admitting the CR | none; run `preflight` + `validate` first |
+| Sweeps / multi-run | `AIPerfSweep` + sweep-controller pod | unsupported |
+| RBAC footprint | cluster-scoped operator ServiceAccount | one Role + RoleBinding in the benchmark namespace |
+| `results` default path | operator PVC, works post-pod-GC | requires `--from-pods` while the pod lives |
+| Name collisions | operator reconciles | fails closed on any same-named non-Namespace resource |
+
+### When direct mode is appropriate
+
+No cluster-admin rights to install the CRD/operator; a single tenant namespace
+whose RoleBinding cannot go cluster-wide; a one-off benchmark needing no
+cross-run history; or a CI smoke test on an ephemeral cluster. Otherwise use
+operator mode — durable results, dashboard/analytics, multi-user management.
+
+### End-to-end direct-mode sequence
+
+```bash
+# 1. Deploy
+aiperf kube profile --model Qwen/Qwen3-0.6B --url http://server:8000 \
+    --image ghcr.io/nvidia/aiperf:v1.2.3 --total-workers 10 \
+    --concurrency 100 --namespace aiperf-bench --no-operator --detach
+
+# 2. Reattach any time before the JobSet TTL expires
+aiperf kube attach --namespace aiperf-bench
+
+# 3. Pull results off the controller pod BEFORE the TTL reaps it
+aiperf kube results --from-pods --shutdown --namespace aiperf-bench
+```
+
+Resource names are `aiperf-<name>` for the JobSet; the ConfigMap adds
+`-config`, the Role adds `-role`, the RoleBinding adds `-binding`. `<name>` is
+`--name` or the auto-generated `<model>-<endpoint-type>-<phase-type>` slug. The
+CLI prints one `Created <Kind>/<name>` line each. The target namespace must
+already exist -- the CLI never creates it. An existing resource is reused and
+reported as `already exists`.
+
+Preview without submitting — works with no cluster and no kubeconfig; the
+memory estimate goes to stderr, so the redirect yields clean YAML:
+
+```bash
+aiperf kube profile --model Qwen/Qwen3-0.6B --url http://server:8000 \
+    --image aiperf:latest --no-operator --dry-run > bench.yaml && \
+    kubectl apply -f bench.yaml
+```
+
+### Direct-mode results retrieval
+
+`--from-pods` port-forwards to the controller pod's API service (port 9090)
+and downloads the exported artifacts. The default `--all` path has **no**
+fallback tier — if that API is unreachable, retrieval fails outright. Only
+`--summary-only` retries with `kubectl cp` against the `control-plane`
+container's `/results`. The pod also runs a results sidecar on port 9091 over
+the same volume, but `--from-pods` never targets it (only the operator's
+completion fetch does). `--run` is rejected with `--from-pods`, since pods hold
+only the latest run. `--shutdown` (effective only with `--from-pods`) tells the
+controller API to exit after a successful download so the pod terminates.
+
+An interactive foreground direct-mode `profile` (TTY stdout, no `--detach`)
+already waits for the controller pod, tails its `control-plane` container, and
+on completion downloads all artifacts plus per-pod logs into
+`./artifacts/<job_id>/`, so the explicit `results` call is only needed for
+detached and non-TTY runs.
+
+### Direct-mode cleanup
+
+`delete` and `cleanup` resolve `AIPerfJob`/`AIPerfSweep` CRs only; on a
+direct-mode run they print not-found and exit 0 while the JobSet keeps running.
+Tear down manually:
+
+```bash
+kubectl delete jobset      aiperf-<name>        -n <namespace>
+kubectl delete configmap   aiperf-<name>-config -n <namespace>
+kubectl delete role        aiperf-<name>-role    -n <namespace>
+kubectl delete rolebinding aiperf-<name>-binding -n <namespace>
+kubectl delete namespace   <namespace>          # only if dedicated to the run
+```
+
+TTL reaps completed pods eventually; ConfigMap, Role and RoleBinding stay.
+
+### Direct-mode limitations
+
+- No cross-job analytics, dashboard, leaderboard, compare, or run history.
+- Results are lost if the pod is deleted before `results --from-pods` runs.
+- No operator-side admission/validation; `--skip-endpoint-check` is a no-op.
+- No CR lifecycle reconciler: `timeoutSeconds`, `resultsTtlDays`, `cancel` and
+  `failurePolicy` need the operator. JobSet-native `ttlSecondsAfterFinished`
+  and `keepFailedPods` still apply.
+- No CR-level status: use `kubectl get jobset`, `kubectl get pods -l app=aiperf`,
+  `aiperf kube logs`, and `aiperf kube list` (which falls back to JobSets).
+- Refuses to adopt an existing Role, RoleBinding, ConfigMap or JobSet of the
+  same name, whatever its phase — no owner CR or run UID can prove ownership.
+  Use a unique `--name` or delete the prior resources.
+
+## Per-command flag reference
+
+`attach`, `logs`, `results`, `results list-runs`, `cancel`, `delete` and
+`shutdown` all take an optional positional `job_id` (or sweep name), defaulting
+to the last deployed benchmark; `list` takes an optional `job_id` to show one.

+
+Checks YAML structure, `apiVersion`/`kind`/`metadata.name`/`spec.endpoint`,

+
+`--operator` and `--no-operator` together is a startup error. A config carrying
+`sweep:` — or `multi_run:` needing multiple trials — is rejected with a pointer
+to the sweep path; an `AIPerfSweep` CR is rejected in favour of `kubectl apply`.
+
+Foreground operator mode polls the CR until `Completed`/`Failed`/`Cancelled` or
+a hard 600 s timeout (`AIPERF_K8S_WATCH_DEFAULT_TIMEOUT_SECONDS`, max 86400);
+Ctrl+C and the timeout both leave the cluster-side run intact.

+
+| Flag | Default | Semantic |
+|---|---|---|
+| `-A`, `--all-namespaces` | **true** | Search all namespaces; ignored when `--namespace` is set |
+| `--running` / `--completed` / `--failed` | false | Phase filter; more than one exits 1 |

+| `--watch` | false | Refresh until interrupted |
+| `--interval` | `5` | Refresh seconds, with `--watch` |
+
+Falls back to listing JobSets when no `AIPerfJob` CRs match.
+
+### `aiperf kube logs`
+
+| Flag | Default | Semantic |
+|---|---|---|
+| `--container` | all | Specific container |
+| `-f`, `--follow` | false | Stream in real time |
+| `--tail` | all | Lines from the end |
+| `-o`, `--output` | stdout | Directory for per-pod log files |
+| `-v`/`-t` | none | Sweep child addressing |
+| `--ignore-not-found` | false | Exit 0 instead of 1 when the target is missing |
+
+### `aiperf kube results`
+
+| Flag | Default | Semantic |
+|---|---|---|
+| `--output` | `./artifacts/<name>` | Output dir (`./artifacts/<ns>__<job>__<epoch>` with `--run`; `./artifacts/sweep__<ns>__<name>` for a sweep) |
+| `--from-pods` | false | Pull from the controller API instead of the operator PVC |
+| `--all` / `-a` (negated by `--summary-only`) | `--all` | All artifacts vs. summary only; only `--summary-only` has the `kubectl cp` fallback |
+| `--shutdown` | false | Stop the API service after download; only with `--from-pods` |
+| `--port` | `0` (ephemeral) | Local port for the port-forward |
+| `--operator-namespace` | auto-detected | Where the operator runs |
+| `--run` | latest | Pin a historical run by epoch; incompatible with `--from-pods` |
+| `-v`, `--variation` / `-t`, `--trial` | none | Download one sweep child instead of the whole sweep |
+
+Exits 1 when the target cannot be resolved or any requested file fails to
+download, partial sweep downloads included.
+
+### `aiperf kube results list-runs`
+
+Lists a job's historical runs from the operator. `-o`/`--output` is `text`
+(default) or `json`; `--preview` annotates which runs current retention would
+reap (read-only, latest always protected); `--operator-namespace` and
+`-v`/`-t` behave as in `results`.
+
+### `aiperf kube cancel`
+
+| Flag | Default | Semantic |
+|---|---|---|
+| `-v`, `--variation` / `-t`, `--trial` | none | Sweep child addressing |
+| `--kind` | inferred | `job` or `sweep` when both share a name |
+
+Patches `spec.cancel: true`; already-terminal targets are a no-op. The operator
+deletes the JobSet and sets `phase=Cancelled` **without harvesting** — download
+results before cancelling.
+
+### `aiperf kube delete`
+
+| Flag | Default | Semantic |
+|---|---|---|
+| `-f`, `--force` | false | Skip the confirmation prompt |
+| `--kind` | inferred | `job` or `sweep` when both share a name |
+
+Deletes the CR; JobSet, pods and ConfigMap follow via ownerReferences, and PVC
+results are untouched. Without a TTY the confirmation auto-declines (as it does
+for `cleanup`), so `--force` is mandatory in CI.
+
+### `aiperf kube cleanup`
+
+| Flag | Default | Semantic |
+|---|---|---|
+| `-a`, `--all` | false | Also remove running benchmarks (cancelled first) |
+| `-f`, `--force` | false | Skip the confirmation prompt |
+| `--dry-run` | false | List what would go, delete nothing |
+
+Default scope is terminal only — jobs `Completed`/`Failed`/`Cancelled`, sweeps
+`Succeeded`/`Failed`/`Cancelled`/`PartiallyFailed`.
+
+### `aiperf kube shutdown`
+
+`--local-port` (default `0` = ephemeral) sets the API port-forward's local
+port. POSTs `/api/shutdown` to the controller API; HTTP 409 while the run is
+still going — cancel it instead. Harvested results remain available.

+description: Use when preparing a real multi-node Kubernetes cluster for AIPerf - installing or upgrading the aiperf-operator Helm chart, installing JobSet, wiring a private registry pull secret, choosing node placement and a storage class for the results PVC, or scoping the operator to namespaces.
+---
+
+# Preparing a Real Cluster for AIPerf
+
+Everything that happens once per cluster, before any benchmark is submitted.
+This targets a real multi-node cluster (shared dev, DGXC, on-prem, cloud):
+tainted node pools, a private registry, a non-default storage class, RBAC you
+do not fully own.
+
+**Related skills:** `aiperf-kube-run` (submit a benchmark once this is done),
+`aiperf-kube-triage` (operator installed but jobs misbehave).
+
+## 1. Inventory the cluster before you install
+
+Never carry another cluster's manifest over unread. Node pool labels, taints,
+arch, storage classes, and pull-secret names differ per cluster and are the
+top source of "installed fine, every job Pending".
+
+```bash
+CTX=<your-context>                     # always pass --context explicitly
+kubectl --context "$CTX" get nodes -L kubernetes.io/arch -L nvidia.com/gpu.product
+kubectl --context "$CTX" get nodes -o custom-columns=\
+NAME:.metadata.name,GPU:.status.allocatable.nvidia\\.com/gpu,TAINTS:.spec.taints
+kubectl --context "$CTX" get storageclass
+kubectl --context "$CTX" get crd jobsets.jobset.x-k8s.io
+```
+
+| Requirement | Verify |
+|---|---|
+| Kubernetes v1.24+, kubectl authenticated | `kubectl cluster-info` |
+| JobSet controller (hard dependency of operator mode) | `kubectl get crd jobsets.jobset.x-k8s.io` |
+| NVIDIA device plugin, if benchmarking GPU-resident servers | GPU column above is non-empty |
+| Helm v3 and the AIPerf CLI locally | `helm version`, `aiperf --version` |
+| Registry access for the operator image | `docker login <registry>` |
+
+Record four things before writing any values file: the node pool label you may
+schedule on, the taints you must tolerate, the storage class name, and the
+pull-secret name.
+
+## 2. Install JobSet
+
+The chart grants RBAC for `jobset.x-k8s.io` but does **not** install JobSet.
+AIPerf pins JobSet `v0.8.0`. Install that version unless you have a reason to
+diverge, and keep the pin and this step in step with each other.
+
+```bash
+kubectl --context "$CTX" apply --server-side \
+  -f https://github.com/kubernetes-sigs/jobset/releases/download/v0.8.0/manifests.yaml
+kubectl --context "$CTX" -n jobset-system \
+  wait --for=condition=available --timeout=120s deployment/jobset-controller-manager
+```
+
+## 3. Namespaces and the registry pull secret
+
+Two namespaces: one for the operator, one for benchmark pods. The chart
+creates neither, so create both yourself.
+
+```bash
+NS_OP=aiperf-system
+NS_BENCH=my-benchmarks
+kubectl --context "$CTX" create ns "$NS_OP"
+kubectl --context "$CTX" create ns "$NS_BENCH"
+
+for ns in "$NS_OP" "$NS_BENCH"; do
+  kubectl --context "$CTX" -n "$ns" create secret docker-registry regcred \
+    --docker-server=<registry> --docker-username=<user> --docker-password=<token>
+done
+```
+
+The secret is needed in **both**: the operator namespace pulls the operator
+image, the benchmark namespace pulls the benchmark image for every job pod.
+
+## 4. Install the operator from a values file
+
+Use a checked-in overlay, not a pile of `--set` flags — the placement and
+storage fields are the ones you will revisit.
+
+```yaml
+# aiperf-operator-values.yaml
+image:
+  repository: <registry>/aiperf
+  tag: <immutable-tag>
+imagePullSecrets:
+  - name: regcred
+operator:
+  nodeSelector: {nodeGroup: <cpu-pool>}
+  tolerations: []                 # replace the chart defaults; see below
+  watchNamespaces: [my-benchmarks]
+storage:
+  size: 1Ti
+  storageClassName: <class>
+  accessMode: "ReadWriteOnce"
+benchmarkRbacNamespaces:          # you created these in step 3
+  - my-benchmarks
+```
+
+```bash
+# The chart ships inside the aiperf source tree; there is no published Helm
+# repo. Clone github.com/ai-dynamo/aiperf and point CHART at it, or use your
+# own packaged/OCI copy if your org republishes it.
+CHART=deploy/helm/aiperf-operator     # chart version 0.7.0
+
+helm --kube-context "$CTX" upgrade --install aiperf-operator "$CHART" \
+  --namespace "$NS_OP" -f aiperf-operator-values.yaml --wait --timeout 5m
+```
+
+Other knobs worth knowing, all top-level keys in the chart's `values.yaml`:
+
+| Value | Default | Why you'd change it |
+|---|---|---|
+| `defaults.image` | computed from `image.*` | decouple benchmark image from operator image |
+| `benchmarkRbacNamespaces` | `[]` | benchmarks run in more than one namespace |
+| `serverMetricsDiscoveryNamespaces` | `[]` | scrape server metrics from an existing inference namespace |
+| `kueue.createQueues` / `kueue.defaultQueueName` | `false` / `""` | provision a ResourceFlavor + ClusterQueue + LocalQueue; see the Kueue rule below |
+| `serviceMonitor.enabled` | `false` | Prometheus Operator scraping of operator metrics |
+| `operator.priorityClassName` | `""` | keep the operator off the eviction list |
+| `operator.env` | — | operator lifecycle/results tunables only (9 fixed keys) |
+| `rbac.create` / `networkPolicy.enabled` | `true` / `false` | hardening (read the RBAC rule below before flipping `rbac.create`) |
+| `dashboard.enabled` | `false` | Plotly results UI |
+
+Full values matrix, hardening posture, and CI patterns:
+`references/configuration.md` (bundled with this skill).
+
+## Rules that bite
+
+- **`kueue.defaultQueueName` routes jobs through two independent mechanisms,
+  and only one of them always fires.** It sets
+  `AIPERF_K8S_JOBSET_KUEUE_DEFAULT_QUEUE_NAME` on the operator container — that
+  is what makes the operator stamp `kueue.x-k8s.io/queue-name` on the JobSet and
+  create it `spec.suspend: true`, and it applies unconditionally. Kueue's own
+  webhook instead reads a `kueue.x-k8s.io/default-queue-name` annotation on the
+  benchmark namespace, which the chart does not apply -- annotate the namespace
+  yourself with `kubectl annotate` if you want that half. Per-job
+  `spec.scheduling.queueName` overrides the operator default. AIPerf pins Kueue `v0.10.1`; the chart-created
+  ClusterQueue omits `nvidia.com/gpu` from `coveredResources` unless you set
+  `kueue.resources.gpu`, so GPU benchmarks are not quota-gated by default.
+
+- **The chart's default tolerations are not universal.** `operator.tolerations`
+  ships with `dedicated=user-workload` (`NoSchedule` + `NoExecute`) and
+  `kubernetes.io/arch Exists`. On a cluster that taints differently they are
+  inert, and the operator pod goes `Pending` with no obvious cause. Set the
+  list to your cluster's taints or to `[]` on an untainted pool. Tolerations
+  permit; they do not attract — pair them with `operator.nodeSelector`.
+- **Chart `imagePullSecrets` covers the operator and `helm test` pods only.**
+  Benchmark pods take theirs from the CR (`spec.podTemplate.imagePullSecrets`)
+  or `--image-pull-secrets`. Setting only the chart value yields a healthy
+  operator and `ImagePullBackOff` on every job.
+- **`storage.storageClassName` defaults to `""`, and the PVC then omits the
+  field entirely** — which resolves to the cluster's *default* StorageClass. On
+  a cluster with no default class the PVC pends forever and `helm --wait` times
+  out with nothing obviously wrong. Name the class explicitly, or set
+  `storage.enabled=false` to fall back to an emptyDir bounded by
+  `storage.emptyDirSizeLimit` (results then die with the pod — test clusters
+  only).
+- **A `WaitForFirstConsumer` storage class makes the PVC pend until the
+  operator pod schedules.** That is normal; a PVC pending *after* the pod is
+  Running means the class or zone is wrong.
+- **`accessMode: ReadWriteOnce` binds results to one node.** Fine for the
+  required single operator replica, but node failure strands the volume — use
+  an RWX class if you need results to survive it.
+- **`benchmarkRbacNamespaces` entries must already exist.** The chart renders
+  only the benchmark Role/RoleBinding into them, never the Namespace itself, so
+  a typo or an uncreated namespace fails the install on a missing-namespace
+  error rather than silently creating one.
+- **`operator.watchNamespaces` does not narrow RBAC.** The ClusterRole still
+  grants cluster-wide reads. Narrowing it is not a one-flag change:
+  `rbac.create=false` gates the *whole* benchmark-RBAC template, so it also
+  deletes the benchmark Role/RoleBinding that gives job pods `pods
+  get/list/watch`, `jobsets patch`, and `aiperfjobs/status patch` — the install
+  succeeds and then every benchmark fails. It also does not remove cluster
+  scope on its own: the `helm test` ClusterRole/ClusterRoleBinding still
+  render, so a zero-ClusterRole install needs `rbac.create=false` **and**
+  `tests.enabled=false`, with both the operator and the benchmark RBAC
+  reapplied namespace-scoped out of band.
+- **Mutable tags silently deploy old code.** A rebuilt `:latest` with
+  `pullPolicy: IfNotPresent` reuses whatever is on the node. Use immutable
+  tags, and confirm what actually rolled out.
+- **Multi-arch matters on mixed pools.** An amd64-only image lands
+  `exec format error` on arm64 GPU nodes rather than a pull failure.
+- **The per-container CPU defaults are sized for small runs.**
+  `AIPERF_K8S_RECORDS_MANAGER_CPU` and `AIPERF_K8S_SYSTEM_CONTROLLER_CPU`
+  default to `75m`; past a few hundred thousand requests the records manager
+  pegs a core and heartbeats miss. Raise them before a large campaign, not
+  after it stalls. They are read by the process that renders the JobSet, so
+  they must be set on the **operator container** -- `spec.podTemplate.env` has
+  no effect on container resources, and `operator.env` is a closed 9-key map
+  (monitor/timeout/results tunables) that silently drops anything else:
+
+  ```bash
+  kubectl set env -n "$NS_OP" deploy/aiperf-operator -c operator \
+    AIPERF_K8S_RECORDS_MANAGER_CPU=4000m
+  ```
+
+  Pass `-c operator` or the var also lands on the results-server container.
+  The chart templates the operator env list in full and has no `extraEnv`, so
+  **the next `helm upgrade` silently reverts this** — re-apply it after every
+  upgrade, or the campaign that worked last month stalls this month.
+- **Upgrading the chart does not restart running benchmarks.** In-flight
+  AIPerfJobs keep their old controller image.
+
+## Verify the install
+
+```bash
+kubectl --context "$CTX" get crd | grep aiperf.nvidia.com   # aiperfjobs + aiperfsweeps
+kubectl --context "$CTX" -n "$NS_OP" get pods,pvc           # 2/2 ready (3/3 with dashboard), PVC Bound
+kubectl --context "$CTX" -n "$NS_OP" logs deploy/aiperf-operator -c operator --tail=20
+helm --kube-context "$CTX" test aiperf-operator -n "$NS_OP"
+```
+
+`helm test` pulls `alpine/k8s` from Docker Hub, not from your registry, and the
+chart's `imagePullSecrets` holds credentials for the wrong host. On an
+air-gapped or Docker-Hub-blocked cluster this step fails for reasons unrelated
+to the operator — install with `tests.enabled=false` and verify by hand.
+
+Then the online check, with the arguments a real job will use:
+
+```bash
+aiperf kube preflight --kube-context "$CTX" -n "$NS_BENCH" \
+  --image <registry>/aiperf:<tag> --image-pull-secret regcred \
+  --endpoint-url http://<svc>.<ns>.svc.cluster.local:8000 \
+  --workers 16 -o json | jq '.checks[] | select(.status == "fail" or .status == "warn")'
+```
+
+`preflight` covers apiserver connectivity, API versions, and RBAC honestly.
+Read the other three checks as existence tests, not reachability tests:
+
+- **Image**: parses the reference. Supplying `--image-pull-secret`
+  short-circuits it to `PASS` without contacting the registry, so a typo'd tag
+  or an unpushed local build sails through.
+- **Endpoint**: for a `.svc` host it only confirms the Service *object*
+  exists; anything else returns `INFO` unverified. A Service with zero ready
+  endpoints or a wrong port passes.
+- **Node capacity**: sums `allocatable` across Ready nodes and compares it to
+  the worker projection. It ignores current pod usage, taints, `nodeSelector`,
+  and ResourceQuota, so a full or fully-tainted cluster passes and every pod
+  then goes Pending. It also reads `AIPERF_K8S_*` from the *CLI's* environment,
+  not the operator's, so a raised records-manager CPU is invisible to it.
+
+A clean preflight means "nothing is obviously missing", not "this run will
+schedule". `CheckStatus` also emits
+`skip` and `info` for benign cases, which is why the filter above matches
+`fail`/`warn` rather than everything that is not `pass`. Re-run it
+whenever the worker count or endpoint changes — capacity is the check that
+goes stale. Finish with a small benchmark from `aiperf-kube-run` before
+handing the cluster to anyone else.
+
+The `AIPerfJob`/`AIPerfSweep` CRDs shipped in the chart are generated from the
+operator's Pydantic models. Never hand-edit `templates/crd-aiperfjob.yaml` or
+`templates/crd-aiperfsweep.yaml` in a chart checkout — an upgrade overwrites
+them. From an aiperf source checkout, regenerate with
+`uv run python tools/generate_crd.py` (`--check` verifies without writing).
+
+## Local Kind clusters
+
+Out of scope here: use it for correctness and lifecycle work, not for
+placement, storage, or performance. The differences are a locally built image
+(`kind load` plus `image.pullPolicy=Never`, re-loaded after every rebuild), no
+pull secret, and the default storage class. Everything above about tolerations,
+node pools, and RWX still needs re-deriving on the real cluster.

+
+Terminal reference for the `aiperf-operator` Helm chart: every value group and
+default, production hardening, and Kueue integration. Chart `version: 0.7.0`,
+`appVersion: "0.13.0"`, `kubeVersion: ">=1.24.0-0"`.
+
+## Pinned dependency versions
+
+| Dependency | Pinned version | Notes |
+|---|---|---|
+| JobSet | `v0.8.0` | Hard dependency. The chart grants `jobset.x-k8s.io` RBAC but does **not** install it. |
+| Kueue | `v0.10.1` | Optional. Pinned for the project's own install tooling. |
+| NVIDIA device plugin | `v0.17.0` | Optional, for GPU-resident benchmarks. |
+
+```bash
+kubectl apply --server-side \
+  -f https://github.com/kubernetes-sigs/jobset/releases/download/v0.8.0/manifests.yaml
+kubectl -n jobset-system wait --for=condition=available \
+  --timeout=120s deployment/jobset-controller-manager
+```
+
+## Schema strictness — closed maps
+
+The chart's values JSON schema sets `additionalProperties: false` on the root
+and on `image`, `podTemplate`, `chaos`, `operator`, `operator.metrics`,
+`resultsServer`, `dashboard`, `rbac`, `storage`, `serviceAccount`,
+`kueue`, `ingress`, `networkPolicy`, `serviceMonitor`,
+`defaults`, `tests`, `tests.image`, and object entries of
+`serverMetricsDiscoveryNamespaces`. An unknown key in any of those is a
+**render-time validation error**.
+
+Free-form (extensible) maps: `operator.resources`, `.podAnnotations`,
+`.nodeSelector`, `.affinity`, `resultsServer.resources`, `dashboard.resources`,
+`serviceAccount.annotations`, `ingress.annotations`, `serviceMonitor.labels`
+/`.tlsConfig`/`.bearerTokenSecret`, `kueue.resources`, `tests.resources`.
+
+**`operator.env` is effectively closed even though the schema does not mark it
+so** — the Deployment renders exactly nine env vars from nine named keys; any
+other key there renders nothing.
+
+## Value matrix
+
+### `image` / registry
+
+| Key | Default | Effect |
+|---|---|---|
+| `image.repository` | `nvcr.io/nvidia/aiperf` | Image for every operator-pod container (operator, results-server, dashboard). |
+| `image.tag` | `""` | Falls back to `Chart.AppVersion` (`0.13.0`). Also propagates to benchmark pods unless `defaults.image` is set. |
+| `image.pullPolicy` | `IfNotPresent` | |
+| `imagePullSecrets` | `[]` | List of `{name}`. Operator pod only — benchmark pods need the secret in the benchmark namespace via the CR's pod template. |
+| `nameOverride` | `""` | Replaces chart name in resource names/labels. |
+| `fullnameOverride` | `""` | Replaces the full release name in resource names. |
+
+### `operator` — the kopf container
+
+| Key | Default | Effect |
+|---|---|---|
+| `operator.replicas` | `1` | Any other value calls `fail` at render time. No leader election exists. Deployment `strategy.type: Recreate`. |
+| `operator.resources` | `requests: {cpu: 250m, memory: 256Mi}`, no limits | Burstable on purpose; high-concurrency runs need headroom. |
+| `operator.podAnnotations` | `{}` | |
+| `operator.nodeSelector` | `{}` | |
+| `operator.tolerations` | three entries (see below) | Replaces, does not merge. |
+| `operator.affinity` | `{}` | |
+| `operator.topologySpreadConstraints` | `[]` | |
+| `operator.priorityClassName` | `""` | |
+| `operator.watchNamespaces` | `[]` | Empty renders `--all-namespaces`; each entry renders `--namespace=<ns>`. Does **not** narrow RBAC. |
+| `operator.tmpSizeLimit` | `""` | `sizeLimit` on the `/tmp` emptyDir. Unbounded when empty; exceeding evicts the pod (k8s 1.25+). |
+| `operator.metrics.port` | `9090` | `0` removes the metrics container port, the Service `metrics` port, and the NetworkPolicy metrics rule, and blocks the ServiceMonitor from rendering at all. `AIPERF_METRICS_PORT` is set to this value regardless. |
+
+Default tolerations:
+
+```yaml
+operator:
+  tolerations:
+    - {key: dedicated, operator: Equal, value: user-workload, effect: NoSchedule}
+    - {key: dedicated, operator: Equal, value: user-workload, effect: NoExecute}
+    - {key: kubernetes.io/arch, operator: Exists, effect: NoSchedule}
+```
+
+Deliberately absent: `nvidia.com/gpu:NoSchedule`. The operator is a
+control-plane pod and must not consume GPU nodes.
+
+#### `operator.env` — the nine renderable keys
+
+| Key | Default | Env var |
+|---|---|---|
+| `monitorInterval` | `"10.0"` | `AIPERF_OPERATOR_MONITOR_INTERVAL` |
+| `monitorInitialDelay` | `"5.0"` | `AIPERF_OPERATOR_MONITOR_INITIAL_DELAY` |
+| `jobTimeoutSeconds` | `"0"` (no timeout) | `AIPERF_JOB_TIMEOUT_SECONDS` |
+| `podRestartThreshold` | `"3"` | `AIPERF_POD_RESTART_THRESHOLD` |
+| `resultsTtlDays` | `"30"` | `AIPERF_RESULTS_TTL_DAYS` |
+| `resultsMaxRetries` | `"5"` | `AIPERF_RESULTS_MAX_RETRIES` |
+| `resultsRetryDelay` | `"2.0"` | `AIPERF_RESULTS_RETRY_DELAY` |
+| `endpointCheckTimeout` | `"10.0"` | `AIPERF_ENDPOINT_CHECK_TIMEOUT` |
+| `resultsCompressOnDisk` | `"true"` | `AIPERF_RESULTS_COMPRESS_ON_DISK` (zstd on the PVC) |
+
+Also templated unconditionally: `PYTHONUNBUFFERED=1`,
+`AIPERF_RESULTS_DIR=<storage.mountPath>`, `AIPERF_METRICS_PORT`,
+`AIPERF_K8S_SHARE_PROCESS_NAMESPACE`, `AIPERF_DASHBOARD_PORT`,
+`AIPERF_OPERATOR_BASE_URL=http://<fullname>.<ns>:<resultsServer.port>`.
+
+**Any other `AIPERF_K8S_*` tunable (pod sizing, JobSet TTL, Kueue defaults,
+probes) has no chart value.** Apply it to the live Deployment after install:
+
+```bash
+kubectl -n aiperf-system set env deployment/aiperf-operator -c operator \
+  AIPERF_K8S_WORKER_POD_MEMORY=8Gi AIPERF_K8S_RECORDS_MANAGER_CPU=4000m
+```
+
+### `resultsServer` (FastAPI sidecar) and `dashboard` (Plotly Dash sidecar)
+
+results-server hosts the entire `/api/v1/*` surface (jobs, sweeps, results,
+config, admin, analytics, dashboard proxy); the kopf container serves only
+`/healthz` on 8080. The PVC is mounted read-write in results-server on purpose:
+the SQLite runs index is in WAL mode and a WAL reader must create the `-shm`
+sidecar; read-only is enforced at the SQLite layer instead.
+
+| Key | Default |
+|---|---|
+| `resultsServer.port` | `8081` — also baked into `AIPERF_OPERATOR_BASE_URL`, the Service `results` port, the Ingress default backend port, and stamped CR status URLs. |
+| `resultsServer.resources` | `requests {cpu 100m, memory 512Mi}`, `limits {cpu 500m, memory 1Gi}` |
+| `dashboard.enabled` | `false` |
+| `dashboard.port` | `8082` — pod-local only, not on the Service |
+| `dashboard.resources` | `requests {cpu 100m, memory 1Gi}`, `limits {}` |
+
+Toggling it changes **three** containers: it adds the dashboard container (PVC
+read-only) and flips `AIPERF_DASHBOARD_PORT` on the operator container plus
+`AIPERF_DASHBOARD_PORT` and `AIPERF_DASHBOARD_PROXY_ENABLED` on results-server.
+Request path: client → Ingress/port-forward → results-server `:8081` →
+`localhost:<port>`.
+
+### `podTemplate` and `chaos` — benchmark-pod overrides
+
+| Key | Default | Effect |
+|---|---|---|
+| `podTemplate.shareProcessNamespace` | `false` | Renders `spec.shareProcessNamespace: true` on JobSet pods. Weakens isolation; test-only. |
+| `chaos.controllerHttpUrlOverride` | `""` | Collapses per-CR controller routing to one URL. Never in production. |
+| `chaos.apiserverServiceHostOverride` | `""` | Overwrites `KUBERNETES_SERVICE_HOST`. Wrong value = total apiserver loss. |
+| `chaos.apiserverServicePortOverride` | `""` | Overwrites `KUBERNETES_SERVICE_PORT`. |
+| `chaos.apiserverTlsServerNameOverride` | `""` | Preserves TLS verification when dialing an L4 proxy. |
+
+### `storage`
+
+| Key | Default | Effect |
+|---|---|---|
+| `storage.enabled` | `true` | `false` skips the PVC entirely and swaps the `results` volume to `emptyDir`. Results then die with the pod. |
+| `storage.size` | `1Ti` | PVC request. |
+| `storage.storageClassName` | `""` | Omitted from the PVC when empty → cluster default class. |
+| `storage.mountPath` | `/data` | Mounted in every operator-pod container; also `AIPERF_RESULTS_DIR`. |
+| `storage.accessMode` | `ReadWriteOnce` | Sufficient for the mandatory single replica. `ReadWriteMany` available if the provisioner requires it. |
+| `storage.emptyDirSizeLimit` | `""` | Only used when `storage.enabled=false`. |
+
+Sizing: budget by retained runs; `resultsCompressOnDisk=true` stores zstd and
+`operator.env.resultsTtlDays` (30) bounds growth. `Recreate` strategy means a
+`ReadWriteOnce` PVC never deadlocks on volume attach during upgrade.
+
+### `serviceAccount`, `rbac`, and namespaces
+
+| Key | Default | Effect |
+|---|---|---|
+| `serviceAccount.create` | `true` | |
+| `serviceAccount.name` | `""` | **Required** when `create=false`: the template calls `required` and fails the render rather than silently binding the namespace `default` SA and 403-ing on every reconcile. |
+| `serviceAccount.annotations` | `{}` | e.g. IRSA / workload-identity. |
+| `rbac.create` | `true` | Gates ClusterRole **and** ClusterRoleBinding **and** the whole benchmark-RBAC template. |
+| `benchmarkRbacNamespaces` | `[]` | Extra namespaces beyond the release namespace that get the benchmark Role/RoleBinding. **Not created** — they must already exist. De-duplicated against the release namespace. |
+| `serverMetricsDiscoveryNamespaces` | `[]` | Existing inference namespaces. **Not created.** Each gets only a `pods: get/list/watch` Role bound to subjects from the benchmark namespaces. |
+
+```yaml
+serverMetricsDiscoveryNamespaces:
+  - dynamo-server                    # binds `default` SA of every benchmark ns
+  - namespace: dynamo-staging
+    serviceAccounts: [aiperf-bench]  # binds custom SAs instead
+```
+
+### `ingress`, `networkPolicy`, `serviceMonitor`, `defaults`, `tests`
+
+| Key | Default | Effect |
+|---|---|---|
+| `ingress.enabled` | `false` | Otherwise ClusterIP + port-forward. |
+| `ingress.className` | `""` | Cluster default IngressClass. |
+| `ingress.annotations` | `{}` | |
+| `ingress.hosts` | `[{host: aiperf.example.com, paths: [{path: /, pathType: Prefix}]}]` | Per-path `pathType` defaults to `Prefix`; backend port defaults to `resultsServer.port`, overridable per path with `portNumber`. |
+| `ingress.tls` | `[]` | List of `{hosts, secretName}`. |
+| `networkPolicy.enabled` | `false` | See hardening below. |
+| `networkPolicy.allowedNamespaces` | `[]` | Extra namespaces on both ingress and egress. |
+| `networkPolicy.allowedIngressCIDRs` | `[]` | `ipBlock` allow-list for external scrapers. |
+| `serviceMonitor.enabled` | `false` | Renders only when also `monitoring.coreos.com/v1` exists **and** `operator.metrics.port > 0`; silent no-op otherwise. |
+| `serviceMonitor.interval` | `30s` | |
+| `serviceMonitor.scrapeTimeout` | `10s` | |
+| `serviceMonitor.honorLabels` | `true` | |
+| `serviceMonitor.scheme` | `http` | |
+| `serviceMonitor.labels` | `{}` | e.g. `release: prometheus-stack`. |
+| `serviceMonitor.tlsConfig` | `{}` | |
+| `serviceMonitor.bearerTokenSecret` | `{}` | `{name, key}`. |
+| `defaults.image` | `""` | Benchmark-pod image; computed `<image.repository>:<image.tag\|AppVersion>` when empty. |
+| `defaults.imagePullPolicy` | `IfNotPresent` | |
+| `tests.enabled` | `true` | Gates the `helm test` hook pods **and** their dedicated SA/Role/RoleBinding/ClusterRole/ClusterRoleBinding. Deliberately *not* gated on `rbac.create`. With it false, `helm test` prints `TEST SUITE: None` and exits 0. |
+| `tests.image.repository` | `alpine/k8s` | Must provide `kubectl` and `curl`. |
+| `tests.image.tag` | `"1.33.11"` | Pinned, not `latest`. |
+| `tests.image.pullPolicy` | `IfNotPresent` | |
+| `tests.resources` | `requests {cpu 50m, memory 64Mi}`, `limits {cpu 200m, memory 128Mi}` | |
+
+## Ports summary
+
+| Port | Container | Exposed on Service |
+|---|---|---|
+| 8080 | operator (kopf `--liveness`, `/healthz`) | yes, `health` |
+| `resultsServer.port` = 8081 | results-server, all `/api/v1/*` | yes, `results` |
+| `operator.metrics.port` = 9090 | operator Prometheus `/metrics` | yes, `metrics` (when > 0) |
+| `dashboard.port` = 8082 | dashboard | **no** — proxied through 8081 |
+
+## Production hardening
+
+### RBAC scoping and what narrowing breaks
+
+The ClusterRole grants, cluster-wide:
+
+| API group | Resources | Verbs |
+|---|---|---|
+| `apiextensions.k8s.io` | customresourcedefinitions | get, list, watch |
+| `aiperf.nvidia.com` | aiperfjobs(+/status,/finalizers) | full |
+| `aiperf.nvidia.com` | aiperfsweeps(+/status,/finalizers) | full |
+| `jobset.x-k8s.io` | jobsets | create, delete, get, list, patch, update, watch |
+| `jobset.x-k8s.io` | jobsets/status | get, list, watch |
+| `kueue.x-k8s.io` | localqueues | get, list |
+| `batch` | jobs | get, list, watch |
+| `apps` | deployments | get, list, watch |
+| `""` | serviceaccounts | get, list, watch, create |
+| `""` | resourcequotas | get, list |
+| `""` | secrets | **get only** |
+| `networking.k8s.io` | networkpolicies | get, list, watch |
+| `""` | configmaps | create, delete, get, list, patch, update, watch |
+| `""` | services, endpoints | create, delete, get, list, watch |
+| `rbac.authorization.k8s.io` | roles, rolebindings | create, delete, get, list, watch |
+| `""` | namespaces | get, list, watch |
+| `""` | pods, pods/log | **get, list, watch only** |
+| `""` | nodes | get, list |
+| `""` | events | get, list, watch, create, patch |
+
+Load-bearing omissions — do not "fix" them:
+
+- **No `pods: patch`.** Pod-restart detection is an event handler precisely
+  because a field handler would need a diff-base annotation on every observed
+  Pod. The `pods`/`pods/log` rule must never gain `create`, `delete`, `patch`,
+  or `update`; check the rendered ClusterRole with
+  `helm template aiperf-operator "$CHART" | yq 'select(.kind=="ClusterRole").rules'`.
+- **`secrets: get` without `list`/`watch`.** Preflight reads referenced pull
+  secrets by name; `list` would expose every secret in the cluster.
+- **No `coordination.k8s.io/leases`.** No leader election exists — hence
+  `replicas: 1`.
+
+What breaks when you narrow:
+
+| Narrowing | Consequence |
+|---|---|
+| `operator.watchNamespaces: [ns…]` | Only limits kopf's watch. RBAC stays cluster-wide. CRs elsewhere are ignored, not rejected. |
+| `rbac.create=false` | Removes ClusterRole + ClusterRoleBinding **and** the per-namespace benchmark Role/RoleBinding **and** the `-metrics-discovery` Roles/RoleBindings. Recreating only the first four silently loses cross-namespace server-metrics discovery. You must also set `serviceAccount.name`. |
+| Drop `kueue.x-k8s.io/localqueues` | The queue preflight check always 403s and degrades to WARN. |
+| Drop `resourcequotas` / `secrets` / `networkpolicies` | Corresponding preflight checks degrade; jobs still submit. |
+| `rbac.create=false` + `tests.enabled=false` | The only combination that emits **zero** cluster-scoped RBAC objects. |
+
+Benchmark-namespace Role (bound to the `default` SA of each benchmark
+namespace): `pods get/list/watch`; `jobsets get/list/watch/**patch**`;
+`aiperfjobs`+`/status` `get/list/watch/**patch**`. `patch` not `update` on
+purpose — `update` (PUT) would let a benchmark pod replace an entire JobSet
+spec.
+
+Pod security is hard-coded, not configurable: pod-level `runAsNonRoot: true`,
+uid/gid/fsGroup `1000`, `seccompProfile: RuntimeDefault`; per-container
+`allowPrivilegeEscalation: false`, `readOnlyRootFilesystem: true`,
+`capabilities.drop: [ALL]`; `terminationGracePeriodSeconds: 30`.
+
+### NetworkPolicy
+
+With `networkPolicy.enabled=true`, one policy targeting the operator pod
+(`Ingress` + `Egress`):
+
+- **Ingress** on 8080, `resultsServer.port`, and `operator.metrics.port` (when
+  > 0) from: the release namespace (needed for `helm test` to reach
+  `/healthz`), every `benchmarkRbacNamespaces` entry,
+  and every `networkPolicy.allowedNamespaces` entry — all matched via the
+  `kubernetes.io/metadata.name` label, so namespace auto-labelling must be on.
+- **Ingress** on the same ports from each `allowedIngressCIDRs` `ipBlock`. Use
+  this for a Prometheus or ingress controller that is not namespace-selectable.
+- **Egress**: UDP/TCP 53 to `kube-system`; TCP 443 and 6443 to **anywhere**
+  (no standard apiserver selector exists); all ports to the benchmark
+  namespace, `benchmarkRbacNamespaces`, and `allowedNamespaces`.
+
+Consequences: an inference endpoint on a non-443 port in a namespace on none of
+those lists is unreachable from the operator, and a Prometheus outside the
+allow-lists cannot scrape even with `serviceMonitor.enabled=true`.
+
+### Resource sizing
+
+Operator pod: `250m`/`256Mi` requested, no limits — raise the request, not a
+limit. Benchmark pod containers are sized by `AIPERF_K8S_*` env vars on the
+operator Deployment (`kubectl set env`, above), not by chart values; requests ==
+limits (Guaranteed QoS). Defaults:
+
+| Container (env prefix `AIPERF_K8S_<NAME>_`) | CPU | Memory |
+|---|---|---|
+| `SYSTEM_CONTROLLER` / `RECORDS_MANAGER` / `API` | 75m | 192Mi / 256Mi / 256Mi |
+| `SWEEP_CONTROLLER` (imports torch+BoTorch) | 75m | 512Mi |
+| `TIMING_MANAGER` / `DATASET_MANAGER` | 50m | 192Mi / 256Mi |
+| `GPU_TELEMETRY_MANAGER` / `SERVER_METRICS_MANAGER` / `RESULTS_SIDECAR` | 25m | 192Mi |
+| `EVENT_BUS_PROXY` | 50m | 64Mi |
+| `WORKER_POD` (workers + record processors + WPM) | 150m | 4Gi |
+
+Known cliff: `AIPERF_K8S_RECORDS_MANAGER_CPU` at the 75m default pegs one core
+above roughly 500k requests; the event loop starves, heartbeats are missed, and
+the CR freezes in `Pending`. Set `4000m` or more for very large runs. Raise
+`AIPERF_K8S_WORKER_POD_MEMORY` for memory-heavy datasets or extreme concurrency
+(1.8-3 GiB working set per pod measured at 10K concurrency).
+
+### High availability and upgrades
+
+No HA by design: `replicas` must be `1`, `strategy: Recreate`, no leader
+election. During a rollout the old pod terminates before the new one starts;
+in-flight benchmarks keep running (they are JobSet pods) and are reconciled on
+restart. Durability comes from the PVC plus a CR annotation gating completion
+work with an atomic test-and-set patch, so restarting mid-completion cannot
+double-fire.
+
+```bash
+helm upgrade aiperf-operator "$CHART" \
+  -n aiperf-system -f values-prod.yaml --wait
+```
+
+The CRDs and the benchmark namespaces carry `helm.sh/resource-policy: keep`, so
+`helm uninstall` leaves running jobs and their CRs intact. Corollary: CRD schema
+changes are **not** applied by `helm upgrade` — apply the new CRDs explicitly
+with `kubectl apply --server-side` when the chart's CRD schema changed.
+
+`topologySpreadConstraints` with one replica constrains which topology the
+single pod may land in; it cannot spread anything. Use `priorityClassName:
+system-cluster-critical` to protect the operator from preemption.
+
+## Kueue
+
+### Install
+
+```bash
+kubectl apply --server-side \
+  -f https://github.com/kubernetes-sigs/kueue/releases/download/v0.10.1/manifests.yaml
+kubectl -n kueue-system wait --for=condition=available \
+  --timeout=300s deployment/kueue-controller-manager
+```
+
+Kueue must have its JobSet integration enabled (`jobset.x-k8s.io/jobset` in the
+controller's `integrations.frameworks`).
+
+### Queue objects
+
+Set `kueue.createQueues=true` to have the chart provision the trio. It renders
+only when the cluster already exposes `kueue.x-k8s.io/v1beta1` — otherwise a
+silent no-op, so install Kueue first.
+
+| Key | Default | Effect |
+|---|---|---|
+| `kueue.createQueues` | `false` | Gates ResourceFlavor + ClusterQueue + LocalQueue. |
+| `kueue.flavorName` | `default-flavor` | ResourceFlavor name (no node labels/taints). |
+| `kueue.clusterQueueName` | `aiperf-cluster-queue` | `namespaceSelector: {}` — all namespaces. |
+| `kueue.localQueueName` | `aiperf-local-queue` | Created in the chart's release namespace. |
+| `kueue.resources.cpu` | `"1000"` | ClusterQueue nominalQuota. |
+| `kueue.resources.memory` | `"4Ti"` | ClusterQueue nominalQuota. |
+| `kueue.resources.gpu` | `""` | **Empty omits `nvidia.com/gpu` from `coveredResources` entirely.** Set e.g. `"64"` to add GPU quota. |
+| `kueue.defaultQueueName` | `""` | Sets `AIPERF_K8S_JOBSET_KUEUE_DEFAULT_QUEUE_NAME` on the operator container. Auto-fills from `localQueueName` when `createQueues=true`. |
+
+Equivalent by hand — note the GPU resource the chart omits unless
+`kueue.resources.gpu` is set:
+

+### The three ways to bind a job to a queue
+
+| # | Mechanism | Who applies it | Operator stamps `queue-name` label + `spec.suspend: true`? |
+|---|---|---|---|
+| 1 | CR `spec.scheduling.queueName` (CLI `--queue-name`) | operator, per job | **yes** |
+| 2 | `AIPERF_K8S_JOBSET_KUEUE_DEFAULT_QUEUE_NAME` on the operator container | operator, cluster-wide fallback | **yes** |
+| 3 | Namespace annotation `kueue.x-k8s.io/default-queue-name` applied by hand | Kueue's own webhook | **no** |
+
+Chart `kueue.defaultQueueName` drives mechanism 2, so setting it is
+sufficient: **yes**.
+
+Mechanism 2 *is* what chart `kueue.defaultQueueName` sets (`operator.env` is a
+fixed nine-key map and does not carry it). To set it without re-running Helm:
+
+```bash
+kubectl -n aiperf-system set env deployment/aiperf-operator -c operator \
+  AIPERF_K8S_JOBSET_KUEUE_DEFAULT_QUEUE_NAME=aiperf-local-queue \
+  AIPERF_K8S_JOBSET_KUEUE_DEFAULT_PRIORITY_CLASS=
+```
+
+Mechanism 3 is the sharp edge. The operator never reads the annotation, so it
+adds no `kueue.x-k8s.io/queue-name` label and no `spec.suspend: true`; admission
+depends entirely on Kueue's webhook and the operator's phase reporting (which
+keys on the label) will not surface `Queued`. The chart never applies the
+annotation, so this mechanism only exists if you apply it yourself:
+
+```bash
+kubectl annotate namespace <your-benchmark-namespace> \
+  kueue.x-k8s.io/default-queue-name=aiperf-local-queue --overwrite
+```
+
+### What the operator does with queue labels
+
+- Resolution is `spec.scheduling.queueName` → env default → none. The label and
+  `spec.suspend: true` use the *same* resolver, so a queue-labelled but
+  unsuspended JobSet (which would bypass gang admission) cannot occur.
+- `spec.scheduling.priorityClass` → `AIPERF_K8S_JOBSET_KUEUE_DEFAULT_PRIORITY_CLASS`
+  → none, stamped as `kueue.x-k8s.io/priority-class`.
+- Gang semantics: controller pod + all worker pods admitted atomically or not.
+- When the JobSet carries the queue label, is suspended, and the CR phase is
+  `Pending` or `Queued`, the reported phase is `Queued`.
+
+### Preflight matrix for the queue check
+
+| Situation | Result |
+|---|---|
+| `queueName` set, LocalQueue exists in the namespace | PASS |
+| `queueName` set, LocalQueue 404 and Kueue installed | FAIL — create the queue or drop `queueName` |
+| `queueName` set, LocalQueue 404 and Kueue absent | FAIL (fails closed — an explicitly queued JobSet would stay suspended forever) |
+| `queueName` set, other HTTP error | WARN |
+| No `queueName`, Kueue not installed | SKIP |
+| No `queueName`, Kueue installed, namespace has the default-queue annotation | PASS |
+| No `queueName`, Kueue installed, no annotation | WARN — job bypasses gang-scheduling and quota |

+name: aiperf-kube-sweep
+description: Use when running a parameter sweep, multi-run confidence trial, or adaptive/Bayesian search on Kubernetes with aiperf kube sweep and the AIPerfSweep CR - authoring sweep parameter axes, addressing child variations, or collecting sweep aggregates.
+---
+
+# Sweeps on Kubernetes
+
+`aiperf kube sweep` submits one `AIPerfSweep` CR. A dedicated sweep-controller
+pod runs the orchestration loop and creates **one child `AIPerfJob` per
+(variation, trial)**, sequentially. The kopf operator has its own
+`AIPerfSweep` handlers (spec validation, RBAC, the controller JobSet, child
+status roll-up) but stays planner-agnostic — the adaptive/BO loop lives only
+in the sweep-controller pod.
+
+**Related skills:** `aiperf-kube-run` (single-job lifecycle, shared flags),
+`aiperf-kube-triage` (a child is stuck). Full grid/zip/scenario and adaptive-
+search reference: `references/adaptive-search.md` (bundled with this skill).
+
+## Quick start
+
+```yaml
+# sweep.yaml
+benchmark:
+  models: [Qwen/Qwen3-0.6B]
+  endpoint:
+    urls: [http://server:8000/v1/chat/completions]
+    type: chat
+    streaming: true
+  datasets:
+    - name: main
+      type: synthetic
+  phases:
+    - name: profiling
+      type: poisson
+      duration: 120
+      concurrency: 8
+      rate: 10
+sweep:
+  type: grid
+  parameters:
+    phases.profiling.concurrency: [4, 8, 16, 32]
+```
+
+```bash
+aiperf kube sweep --config sweep.yaml --image aiperf:latest --dry-run   # preview
+aiperf kube sweep --config sweep.yaml --image aiperf:latest --total-workers 64 --detach
+kubectl get aiperfsweeps -n my-benchmarks
+kubectl get aiperfjobs -l aiperf.nvidia.com/sweep=<sweep-name>
+aiperf kube results <sweep-name>            # whole sweep
+aiperf kube results <sweep-name> -v 7 -t 2  # one child
+```
+
+**`aiperf kube validate` accepts this file.** A bare Config-v2 document with
+no `apiVersion`/`kind` is detected, checked against the `AIPerfSweep` contract
+(inferred from the presence of `sweep:`), and passes with a warning naming the
+contract it used. Only the wrapped-CR form additionally validates deployment
+fields (`image`, `podTemplate`, worker counts, credential transport), so
+validate the CR you would `kubectl apply` when those matter.
+
+**`--dry-run` does not expand anything.** It renders the `AIPerfSweep` CR,
+prints it as JSON, and returns before touching the cluster. It will not show you the variation
+list, the child count, or whether the sweep is over the cardinality caps. To
+see the variation count before you submit, expand it locally (the in-process
+`aiperf profile` sweep path prints the plan) or read the caps below and do the
+multiplication yourself.
+
+## Parameter path rules
+
+- Dotted paths are rooted **inside** the `benchmark:` block:
+  `phases.profiling.concurrency`. A redundant `benchmark.` prefix is rejected
+  by the validator.
+- Bare names (`concurrency`, `rate`, `requests`, `duration`, ...) are sugar for
+  `phases.profiling.<name>`.
+- `variables.<name>` is the one envelope-level escape; it rewrites the top-level
+  Jinja `variables:` block per variation.
+
+## What gets created
+
+| Object | Naming / location |
+|---|---|
+| Parent CR | `kubectl get aiperfsweeps` |
+| Sweep-controller JobSet | one per sweep |
+| Child `AIPerfJob` per (variation, trial) | `<sweep>-v<idx:02d>[-t<trial:01d>]`, labeled `aiperf.nvidia.com/sweep=<sweep>` |
+| Child results | `<base>/<ns>/<sweep>-v07-t2/<child-epoch>/` |
+| Sweep aggregate | `<base>/<ns>/sweeps/<sweep>/<sweep-epoch>/` — `aggregate.json`, `children.json`, `sweep_aggregate/` |
+
+Children address by index everywhere: `results`, `logs`, and `debug` all take
+`--variation` (0..199) and `--trial` (0..9); `--trial` requires `--variation`.
+On `debug`, `--variation` must be spelled long — `-v` is `--verbose` there.
+
+## Rules that bite
+
+- **Credential-bearing axes are rejected before anything is created.** API keys,
+  tokens, passwords, credential-bearing URLs, every `endpoint.headers.*` axis,
+  and credential-like `variables.*` names are refused for grid, zip, scenario,
+  adaptive-search, Sobol, and Latin Hypercube sweeps. Keep credentials fixed and
+  inject them via the Secret-backed endpoint credential env vars
+  (`AIPERF_INJECTED_API_KEY`, `AIPERF_INJECTED_HEADERS`,
+  `AIPERF_INJECTED_ENDPOINT_URLS`), sourced from a Secret you create in the
+  benchmark namespace.
+- **Never nest an in-process sweep inside an operator-managed run.** With
+  `AIPERF_OPERATOR_MANAGED=1` set in a controller pod, any `plan.is_sweep` hard-
+  fails on purpose. The sweep controller strips the parent `multiRun` block from
+  each child so a child executes exactly one run instead of recursing.
+- **The cardinality contract is one AIPerfJob and one controller pod per
+  (variation, trial), and they run one at a time.** The sweep-controller awaits
+  each child to reach a terminal phase before creating the next, so peak
+  cluster demand is a single controller+worker set regardless of grid size.
+  Size `--total-workers` for one child; a 32-way grid at 64 workers needs
+  capacity for 64 workers, not 2048, and needs no Kueue serialization. What
+  scales with the grid is wall-clock, not capacity.
+- **The 200-variation cap is enforced only by the operator at admission; the
+  10-trial cap is also a client-side schema bound.** `multiRun.numRuns` must be
+  1..10, so `numRuns: 11` fails locally — `--dry-run` and `aiperf kube validate`
+  both exit 1 with "Input should be less than or equal to 10". The
+  200-variation cap raises `kopf.PermanentError` in the operator, so the CR is
+  accepted by the apiserver and then goes `Failed` with the cap message in
+  `status.error`, with no retry; `--dry-run` and `validate` both pass on an
+  over-variation sweep. Count your grid before submitting: the product of every
+  axis length must be <= 200.
+- **The aggregate is inlined into CR status only up to ~600 KB**
+  (`AIPERF_K8S_JOBSET_SWEEP_AGGREGATE_INLINE_MAX_BYTES`; the apiserver rejects
+  patches over ~1 MiB with HTTP 413). Past that the sweep-controller drops
+  `confidence` first, then omits `children` and adds a `childrenTruncated`
+  marker if it is still over budget; the full document is served only from the
+  results sidecar / PVC. Read big aggregates via `aiperf kube results`, never
+  from `kubectl get -o json`.
+- **Plotting runs once, in the sweep-controller, after cross-variation
+  aggregation**, and only when `benchmark.artifacts.autoPlot` resolves true.
+  With `benchmark.artifacts.plotRequired: true` a plot failure fails
+  aggregation and withholds the ready marker (nothing is harvested); with
+  `false` it is logged and the aggregate still becomes ready.
+- **A partial sweep download fails `aiperf kube results` (exit 1)** even though
+  the successfully downloaded children remain on disk.
+- **CR object-map keys get alphabetized by the apiserver.** Anything order-
+  sensitive in a sweep spec must be a list of named entries, not a mapping.
+
+## Adaptive / Bayesian search
+
+The sweep-controller instantiates the same Bayesian-optimization planner the
+in-process path uses (`sweep.planner: bayesian`); the K8s executor creates one `AIPerfJob` per iteration, so
+iterations are sequential by construction. Convergence flags
+(`--convergence-metric`, `--convergence-threshold`, `--convergence-mode`,
+`--convergence-stat`, `--confidence-level`, SLO flags) are accepted by
+`aiperf kube sweep` exactly as by the local path. `--bo-constraint-mode` also
+parses but is deprecated and has no effect on either path. See
+`references/adaptive-search.md`.
+
+## Cancelling and cleanup
+
+```bash
+aiperf kube cancel <sweep-name>            # whole sweep
+aiperf kube cancel <sweep-name> -v 7       # one variation
+aiperf kube cancel <name> --kind sweep     # when a job shares the name
+aiperf kube delete <sweep-name> --kind sweep --force
+```
+
+Deleting the parent garbage-collects children through ownerReferences; results
+already harvested to the operator PVC survive.

+
+## The model
+
+One `AIPerfSweep` CR -> one sweep-controller pod (a JobSet the operator
+creates) -> one child `AIPerfJob` per **(variation, trial)**, created
+**sequentially**: the controller awaits each child's terminal phase before
+creating the next, so peak cluster demand is one controller + one worker set
+regardless of grid size. Size worker counts for a single child; what scales
+with the grid is wall clock, not capacity. The kopf operator is
+planner-agnostic — it validates the spec, provisions RBAC, creates the
+controller JobSet, and rolls child status up; the adaptive/BO loop lives only
+inside the controller pod.
+
+| Sweep `type` | Variation count |
+|---|---|
+| `grid` | product of every parameter list length |
+| `zip` | shared parameter-list length (lists must be equal length) |
+| `scenarios` | number of `runs` (names unique and path-safe) |
+| `sobol`, `latin_hypercube` | `samples` |
+| `adaptive_search` | `maxIterations` (upper bound; early stop shrinks it) |
+
+Child names are `<sweep>-v<NN>[-t<N>]`, labeled `aiperf.nvidia.com/sweep=<sweep>`;
+the `-t<N>` suffix appears only when `multiRun.numRuns > 1` or
+`multiRun.convergence` is set. Each child carries
+`aiperf.nvidia.com/run-identity`, a SHA-256 of its generated `AIPerfJob.spec`;
+a deterministic name is reused on restart only when ownership **and** identity
+both match, otherwise the sweep fails rather than feeding a different config's
+metrics into planner history.
+
+## Hard caps (admission-time, `kopf.PermanentError` -> `status.phase: Failed`)
+
+| Cap | Value | Notes |
+|---|---|---|
+| Variations | 200 | variation index 0..199 |
+| Trials per variation | 10 | `multiRun.numRuns` 1..10, also a schema bound |
+| Sweep CR name | 27 chars | child job id capped at 35; worst-case `-vNNN-tN` suffix reserved |
+| BO iterations | `maxIterations` 2..200 | required field, no default |
+| Inline aggregate in CR status | 600 000 bytes | `AIPERF_K8S_JOBSET_SWEEP_AGGREGATE_INLINE_MAX_BYTES`, range 10 000..900 000 |
+
+Over-cap grids are rejected from a cheap shape count **before** expansion, so a
+million-cell grid fails fast instead of stalling the operator. Dry-run and config
+validation both pass on an over-cap sweep — count your grid yourself.

+
+`numRuns: 3` runs three child jobs per proposed point and feeds the pooled objective

+## CLI flags that actually exist on the sweep subcommand
+
+Submission takes a YAML file: a bare AIPerf config with top-level `sweep:` /
+`multiRun:`, or an `AIPerfJob` CR. An `AIPerfSweep` CR is rejected — apply it
+directly instead. Only these sweep-specific flags exist:
+
+| Flag | Maps to | Default |
+|---|---|---|
+| `--trials N` | `multiRun.numRuns` | unset |
+| `--cooldown S` | `multiRun.cooldownSeconds` | `0.0` |
+| `--convergence-metric M` | `multiRun.convergence.metric` | unset |
+| `--min-runs N` | `multiRun.convergence.minRuns` | `3` |
+| `--max-runs N` | `multiRun.numRuns` (raised to at least this) | `10` |
+| `--convergence-threshold F` | `multiRun.convergence.threshold` | unset (per-mode default: `ci_width` 0.10, `cv` 0.05, `distribution` 0.05) |
+| `-d`, `--detach` | reserved; submission always behaves as detached | `false` |
+| `--dry-run` | print the rendered CR as JSON, submit nothing | `false` |
+
+`--min-runs`, `--max-runs`, and `--convergence-threshold` are silently ignored
+unless `--convergence-metric` is also passed. `--max-runs` raises
+`multiRun.numRuns` to *at least* N; it never lowers an authored value.
+
+`aiperf kube sweep` inherits the full benchmark CLI surface, so
+`--convergence-stat`, `--convergence-mode`, `--confidence-level`, the
+`--search-*` family (`--search-space`, `--search-metric`, `--search-stat`,
+`--search-direction`, `--search-max-iterations`, `--search-initial-points`,
+`--search-random-seed`, `--search-planner`, `--search-percentile-pooling`,
+`--search-sla`, `--search-sla-tier`, `--search-recipe`, `--search-style`) and
+the SLO/goodput flags (`--slo-attainment-fraction`, `--goodput`) all parse. The
+table above lists only the sweep-specific flags; anything not listed is either
+inherited from the benchmark surface or authored in YAML. `--bo-constraint-mode`
+parses but is deprecated and ignored. Passing `--convergence-metric` also forces
+`sweep.iterationOrder: independent` when unset, and synthesizes a one-cell
+sweep when there is no `sweep:` block. `--dry-run` renders the CR and returns;
+it never expands variations, so it shows neither the variation list nor whether
+you are over the caps.
+
+## Status fields worth watching
+
+| Field | Meaning |
+|---|---|
+| `status.phase` | `Pending`, `Running`, `Aggregating`, `Succeeded`, `PartiallyFailed`, `Failed`, `Cancelled` |
+| `status.totalVariations` | upper bound (`maxIterations` for adaptive); rewritten down on early stop |
+| `status.maxTotalRuns` | `totalVariations * multiRun.numRuns`, an upper bound |
+| `status.completedRuns` / `failedRuns` | authoritative child tallies; cancelled children are their own bucket, not failures |
+| `status.runEpoch` | int64 epoch key, also the on-disk results directory name |
+| `status.runStates` | open object: pending / running / completed / failed / cancelled counts |
+| `status.currentChildRef`, `status.currentCell` | active child (`name`, `index`, `label`); `currentCell.label` is the CURRENT column |
+| `status.aggregation`, `status.aggregate`, `status.aggregateRef` | aggregation progress and inlined/pointed aggregate |
+| `status.runtimeRef` | `jobSetName` and `sweepControllerHost` |
+| `status.apiUrl` | `/api/v1/sweeps/<ns>/<name>` on the operator service |
+| `status.conditions`, `status.error` | `ConfigValid` / `Failed` conditions and the rejection message |
+
+`status` is preserve-unknown, so unlisted keys may appear. The BO trajectory
+(every proposed point, per-iteration objective, running best, convergence
+reason) lives in `search_history.json`, never on the CR; a compact projection
+is served as `search_summary` on the sweep detail API route, `null` for
+grid-family sweeps and before harvest. A `slaFilterCount` of zero makes every
+`feasible` flag vacuously true. `bestTrials[].objectiveValues` is positional
+against `objectives` and keeps explicit `null` slots.
+
+Aggregates above the inline cap drop `confidence` first, then omit `children`
+and set a truncation marker; read large aggregates through the results download
+path, not `kubectl get -o json`.
+
+`failurePolicy.onChildFailure` is `continue` (default) or `abort`;
+`failurePolicy.maxFailures` defaults to `0` = unbounded. Some failures within
+budget ends `PartiallyFailed`. `spec.benchmark`, `spec.sweep`, `spec.multiRun`,
+`spec.variables`, `spec.randomSeed`, `spec.failurePolicy`, and
+`spec.childMetadata` are immutable after creation.
+
+## Mutual exclusion and the operator-managed gate
+
+| Combination | Outcome |
+|---|---|
+| `kind: AIPerfJob` with `spec.sweep` set | rejected at admission (CEL `!has(self.sweep)`) |
+| `kind: AIPerfSweep` without `spec.sweep` | rejected at admission (CEL `has(self.sweep)`) |
+| A `sweep:` block nested inside `spec.benchmark` | silently pruned by structural-schema pruning; sweep axes belong on the parent CR |
+| Two sweep types at once | not expressible — `sweep.type` is a discriminated union |
+| Magic-list flags (`--concurrency 10,20,30`) inside a child | rejected inside the child pod |
+
+Every controller and worker pod gets `AIPERF_OPERATOR_MANAGED=1`. Under that
+flag an in-process multi-variation plan hard-fails with `SystemExit`, so the
+cluster can never sweep on top of a sweep. **Adaptive search is exempt by
+construction**: the controller proposes one point at a time and each child sees
+a single-config plan, so the multi-variation shape never arises. The controller
+also strips the parent `multiRun` block out of each child.
+
+## Cancellation
+
+```bash
+kubectl -n <ns> patch aiperfsweep <name> --type=merge -p '{"spec":{"cancel":true}}'
+```
+
+1. A background poller in the controller re-reads the parent CR and flips an
+   in-process cancel flag; the adaptive loop and the child-wait loop both check
+   it at their await boundaries.
+2. The running child is patched with `spec.cancel: true`, drains to a terminal
+   phase, and still contributes its results.
+3. Remaining iterations are skipped; aggregation runs over completed children;
+   `search_history.json` is flushed with `convergenceReason: "cancelled"`.
+
+An explicit parent cancel yields `Cancelled`; out-of-band cancellation of
+individual children counts in a separate bucket and yields `Cancelled` only
+when nothing completed. `search_history.json` is rewritten after every
+iteration, so the completed prefix survives immediately; after a controller
+restart, terminal children with matching run-identity are replayed into a fresh
+planner before execution advances.
+
+Per-variation cancel targets one child by index (`0..199`), optionally with a
+trial index (`0..9`); the trial index requires the variation index. Deleting
+the parent garbage-collects children through ownerReferences; results already
+harvested to the operator PVC survive.
+
+## Output layout
+
+Under the operator results PVC (`AIPERF_RESULTS_DIR`, default `/data`):
+
+```
+<results-dir>/
+  <namespace>/
+    sweeps/
+      <sweep-name>/
+        latest.txt                       # pointer to newest epoch
+        <sweep-run-epoch>/
+          search_history.json            # adaptive only: trajectory + convergenceReason
+          aggregate.json                 # durable parent aggregate
+          children.json                  # child manifest
+          sweep_aggregate/
+            profile_export_aiperf_sweep.json
+            profile_export_aiperf_sweep.csv
+            manifest.json                # epoch lineage of every child run
+            sampling_design.json         # sobol / latin_hypercube only
+    <sweep-name>-v00-t0/                 # child, same layer as a standalone job
+      <child-run-epoch>/
+        profile_export_aiperf.json
+        ...
+    <sweep-name>-v01-t0/
+```
+
+The controller's results dir is an `emptyDir`; the operator harvests the whole
+tree onto the PVC before deleting the JobSet. `sweep_aggregate/` uses one
+mode-agnostic per-combination schema grouped by stamped variation values, so
+readers need not know whether the sweep was grid or adaptive. Downloading a
+sweep whose children only partially succeeded exits non-zero even though the
+successful children land on disk.
+
+Plotting runs once, in the controller, after cross-variation aggregation, and
+only when auto-plot resolves true. With `plotRequired: true` a plot failure
+fails aggregation and withholds the ready marker; with `false` it is logged and
+the aggregate still becomes ready.
+
+## Credential transport for sweeps
+
+**Credential-bearing axes are rejected before any child is created**, for every
+sweep type. The check walks grid/zip `parameters` keys, adaptive/QMC
+`searchSpace` (and `dimensions`) paths, and `scenarios` `runs` bodies. A path
+is credential-bearing when any dotted segment (case- and punctuation-normalized)
+is, or ends/starts with, one of: `apiKey`, `xApiKey`, `authorization`,
+`proxyAuthorization`, `token`, `apiToken`, `authToken`, `accessToken`,
+`bearerToken`, `idToken`, `refreshToken`, `secret`, `clientSecret`, `password`,
+`passwd`, `credential`, `awsAccessKeyId`, `signature`,
+`ocpApimSubscriptionKey`, `xGoogApiKey`, `xFunctionsKey`, `aegSasKey`,
+`xAmzSecurityToken` — **plus any `endpoint.headers.*` path at all**, and any
+value that looks like a credential-bearing URL. `variables.<name>` axes are
+covered too, since the credential name still appears as a segment. Rejection
+message: *"Kubernetes sweeps cannot vary credential-bearing values."*
+Per-variation secret transport does not exist: sweep values are copied into
+child annotations, parent status, aggregates, and API responses.
+
+Keep credentials **fixed** and inject them through Secret-backed pod env vars:
+
+| Variable | Carries |
+|---|---|
+| `AIPERF_INJECTED_API_KEY` | endpoint API key (alias `OPENAI_API_KEY` accepted, but it can only rehydrate a key the config authored-then-redacted) |
+| `AIPERF_INJECTED_HEADERS` | JSON object, string values only — credential-bearing headers |
+| `AIPERF_INJECTED_ENDPOINT_URLS` | JSON list of strings — full endpoint URLs, replacing the authored list |
+
+Submission fails with *"Kubernetes endpoint credentials must come from
+Secret-backed pod environment variables"* if the config carries an API key,
+sensitive header, or credential-bearing URL and the pod template has no
+matching `valueFrom.secretKeyRef` env entry. Wire them with
+`--env-from-secrets.AIPERF_INJECTED_API_KEY <secret>/<key>`, or directly:
+
+```yaml
+spec:
+  podTemplate:
+    env:
+      - name: AIPERF_INJECTED_API_KEY
+        valueFrom:
+          secretKeyRef: {name: llm-endpoint, key: api-key}
+      - name: AIPERF_INJECTED_HEADERS
+        valueFrom:
+          secretKeyRef: {name: llm-endpoint, key: headers-json}
+```
+
+Authored credentials are redacted before persistence, so the serialized run and
+any ConfigMap stay secret-free; injected values are popped from the process
+environment (never left in `/proc/<pid>/environ` for child services) and
+overlaid onto the redacted placeholders at run start. Injected headers override
+same-named authored headers; injected URLs replace the authored list. Any
+placeholder still present after the overlay is a hard error naming the missing
+variable. Labels, annotations, status, manifests, and API responses all run
+through the same redaction projection.

+name: aiperf-kube-triage
+description: Use when an AIPerf benchmark on Kubernetes is stuck, failing, crash-looping, OOM-killed, pending, queued, stalled, showing a high error rate, or its results cannot be retrieved - diagnosing an AIPerfJob or AIPerfSweep from CR status, pod state, and logs.
+---
+
+# Triaging an AIPerf Kubernetes Run
+
+Classify first, then follow the branch. Do not read logs before you know the
+phase — the phase determines which logs matter.
+
+**Related skills:** `aiperf-kube-run` (lifecycle and exit codes),
+`aiperf-kube-setup` (cluster/operator install problems).
+
+The machine-parseable playbook with full JSON schemas and jq/python snippets is
+`references/debugging.md` (bundled with this skill). This skill is the routing
+layer.
+
+## Step 1: classify
+
+```bash
+kubectl get aiperfjob <NAME> -n <NS> -o json | jq '{
+  phase: .status.phase, subPhase: .status.subPhase,
+  workers: .status.workers, error: .status.error,
+  conditions: .status.conditions }'
+
+aiperf kube debug -j <NAME> -n <NS> --verbose
+```
+
+`aiperf kube debug` reports pod states, recent events, node resources, and a
+slice of logs from any pod with problems. `-A` inspects all namespaces. For a
+sweep child, pass `--variation <idx>` (long form only — `-v` is `--verbose`
+here) and `-t <trial>`.
+
+## Step 2: branch on `status.phase`
+
+| Phase / symptom | Likely cause | Next command |
+|---|---|---|
+| `Pending` > ~60 s | Unschedulable pods | `kubectl get pods -n <NS> -l aiperf.nvidia.com/job-id=<ID>` then read `PodScheduled` reason |
+| `Queued` | Kueue has not admitted the workload | `kubectl get workloads -n <NS>` and read `.status.conditions[?(@.type=="QuotaReserved")]` |
+| `Initializing` > ~120 s | Image pull, ConfigMap, or ZMQ connection probe | `aiperf kube logs <ID> --container control-plane --tail 50` |
+| `Running`, restarts > 3 | Crash loop | `aiperf kube logs <ID> --container <c> --tail 100` |
+| `Running`, OOM-killed pod | Node memory pressure, *not* a container limit (see below) | `kubectl describe node` for pressure; raise `AIPERF_K8S_WORKER_POD_MEMORY` / `AIPERF_K8S_SYSTEM_CONTROLLER_MEMORY` on the **operator** deployment |
+| `Running`, `requestsCompleted` flat | Stalled benchmark | check endpoint reachability from inside the cluster |
+| `Running`, `request_error_rate.avg > 5` | Endpoint rejecting requests (the metric is a **percent**, so 5 means 5%) | inspect worker logs and server-side errors |
+| `Failed` | See failure table below | `kubectl ... .status.error` + controller logs |
+| `Cancelled` | Someone (or `spec.cancel`) stopped it | no action |
+| `Completed` | Done | `aiperf kube results` |
+
+`request_error_rate.avg` in `status.liveMetrics.metrics` is the **only** error
+signal published while a job runs — `error_request_count` is `ERROR_ONLY` and is
+filtered out of live metrics. Do not conclude "no errors" from its absence.
+
+## Step 3: failure patterns
+
+| `status.error` contains | Root cause | Fix |
+|---|---|---|
+| `preflight` | Cluster validation failed | `aiperf kube preflight -o json`, fix failing checks |
+| `endpoint`, `health check` | Server unreachable from the cluster | resolve the URL from inside a pod, not from your laptop |
+| `timeout` | Exceeded `spec.timeoutSeconds` | raise it, or set `0` |
+| `ConfigMap`, `size` | Config over the 1 MiB object limit | shrink the config / move data to a mounted file |
+| `image`, `pull` | Image not accessible | check tag and `imagePullSecrets`; on Kind, `kind load` + `pullPolicy: Never` |
+| `RBAC`, `forbidden` | Missing permissions | check service account, Role, RoleBinding |
+
+Scheduling messages map directly to causes: `Insufficient cpu/memory` -> lower
+`--total-workers`; `nvidia.com/gpu` -> no free GPU nodes; `didn't match Pod's
+node affinity/selector` -> wrong `spec.podTemplate.nodeSelector`; `had
+untolerated taint` -> missing `spec.podTemplate.tolerations`; `quota` ->
+namespace ResourceQuota exhausted.
+
+**None of those are patchable on the live CR.** Nineteen `spec` fields are
+immutable after creation — `image`, `imagePullPolicy`, `benchmark`,
+`resourceMode`, `connectionsPerWorker`, `ttlSecondsAfterFinished`,
+`resultsTtlDays`, `keepFailedPods`, `podTemplate`, `scheduling`,
+`schemaVersion`, `sweep`, `multiRun`, `plot`, `variables`, `randomSeed`,
+`noSweepTable`, `skipEndpointCheck`, `failurePolicy`. Only `timeoutSeconds` and
+`cancel` accept an update; everything else rejects the patch with
+`spec.<field> is immutable after creation`. So every scheduling, placement,
+resource, priority, or workload fix means **delete and resubmit**, not
+`kubectl edit`.
+
+## Rules that bite
+
+- **A benchmark that looks hung at high concurrency is often CPU starvation of a
+  single service, not a deadlock.** The records-manager and system-controller
+  default to `75m` CPU (`AIPERF_K8S_RECORDS_MANAGER_CPU`,
+  `AIPERF_K8S_SYSTEM_CONTROLLER_CPU`). At very high request rates a pegged core
+  starves the event loop, heartbeats expire, and the CR freezes mid-phase. Raise
+  the CPU before hunting for a logic bug.
+- **The default `resourceMode` is `burstable`, so pods have requests and no
+  limits.** `spec.resourceMode` defaults to `burstable`
+  and emits `requests` only. That means
+  a container cannot be cgroup-OOM-killed for exceeding its memory budget and
+  cannot be CFS-throttled for exceeding its CPU budget — the `75m`/`150m`
+  numbers are scheduling hints, not ceilings. Two consequences: an `OOMKilled`
+  container is evidence of *node* memory pressure or kubelet eviction, not of a
+  too-small `AIPERF_K8S_*_MEMORY`; and a starving service is losing a fair-share
+  race against co-tenants, which raising the request fixes only indirectly (by
+  moving the pod or reserving more share). Set `resourceMode: guaranteed` if you
+  actually want the env budgets enforced as limits, and expect real OOM kills
+  once you do.
+- **Heartbeat expiry is a symptom, not a cause.** `AIPERF_K8S_CONTROLLER_HEARTBEAT_EXPIRY_SECONDS`
+  defaults to 30 s and must be at least twice the interval; widening it hides
+  the starvation instead of fixing it.
+- **Workers pass two startup probes, and they fail differently.** The PUB/SUB
+  connection probe fails *closed*: the pod exits on purpose so Kubernetes
+  restarts it with a fresh ZMQ context
+  (`AIPERF_K8S_JOBSET_WORKER_CONNECTION_PROBE_TIMEOUT`, backoff limit 20). A
+  few early restarts on first deploy are expected, not a bug. The credit-return
+  PUSH probe fails *open*: credit dispatch rides the DEALER but returns ride a
+  separate PUSH/PULL fan-in, and on budget expiry
+  (`AIPERF_WORKER_RETURN_PROBE_BUDGET`, default 30 s;
+  `AIPERF_WORKER_RETURN_PROBE_RETRY_DELAY`, default 0.1 s) the worker announces
+  dispatchability anyway and logs a warning. So a dead return path produces a
+  stalled run with **zero restarts** -- grep worker logs for
+  `Credit-return channel still has no peer` before blaming the endpoint.
+- **Operator-mode results are harvested only on terminal phase.** "results
+  missing" mid-run is correct behavior; use `--from-pods` to read the live
+  controller instead.
+- **On a successful run the pods do not last 300 s — they are deleted at
+  once.** `AIPERF_K8S_JOBSET_TTL_SECONDS_AFTER_FINISHED` (300 s) is only the
+  fallback: once the operator has harvested results it calls
+  its post-success cleanup and deletes the JobSet immediately. The TTL window is real only for failed runs and for partial
+  harvests that are being retried. Never plan to "grab the logs after it
+  finishes" — stream them with `--follow` during the run, or accept that a
+  clean success leaves you only the PVC artifacts. Direct (operator-less) mode
+  is the opposite: `AIPERF_K8S_JOBSET_DIRECT_MODE_TTL_SECONDS` defaults to
+  28800 s (8 h) so pods stay around for manual retrieval.
+- **`debug`, `cancel`, `delete`, `list` exit 0 on a missing target** by design.
+  Never gate a script on their exit status; use `attach` or `logs`.
+- **First deploy attempts flake more than steady state** (ConfigMap propagation,
+  ZMQ probe). One clean retry before deep investigation is a legitimate step.
+
+## Diagnosis thresholds
+
+`aiperf kube debug` findings are tunable via `AIPERF_K8S_DIAGNOSIS_*`:
+`STALLED_PENDING_THRESHOLD_SECONDS` (60), `STALLED_RUNNING_THRESHOLD_SECONDS`
+(30), `HIGH_ERROR_RATE_THRESHOLD` (0.05), `FAIL_ABOVE_ERROR_RATE` (1.0),
+`HIGH_LATENCY_P99_MULTIPLIER` (10). Full env-var table in
+`references/debugging.md`.
+
+## Log collection
+
+```bash
+aiperf kube logs <ID> -n <NS> -o ./triage --ignore-not-found   # per-pod files
+aiperf kube logs <ID> --container control-plane --follow
+```
+
+Containers worth naming: `control-plane` (SystemController), `api`,
+`event-bus-proxy`, worker containers. Save logs to a directory before the TTL
+reaps the pods.

+
+## 2. CR `.status` schema
+
+`phase` (enum `Pending|Queued|Initializing|Running|Completed|Failed|Cancelled`),
+`jobId`, `jobSetName`, `startTime`, `completionTime`, `observedGeneration`,
+`error`, `conditions[]`,
+`workers{ready,total,dispatchable,routerConnected,readyRecordProcessors,declaredRecordProcessors,readyPods,totalPods,degradedPods}`,
+`phases{<name>:{requestsCompleted,…}}`,
+`requestsCompleted`, `requestsTotal`, `requestsPerSecond`,
+`currentPhase` (inner benchmark stage),

+`resultsTtlDays`,
+`startupIssue{fingerprint,podName,containerName,reason,message,category,terminalAfterThreshold,firstObservedTime,warningEmitted}`
+where `category` is `ContainerConfig|CrashLoop|ImagePull|SchedulingConstraint|SchedulingDelay`.
+
+`subPhase` is mirrored to the annotation `aiperf.nvidia.com/system-state`. Pod
+selector `aiperf.nvidia.com/job-id=<JOB_ID>` (also `app=aiperf`,
+`aiperf.nvidia.com/{name,parent,trial}`). Containers — controller pod:
+`control-plane`, `dataset-manager`, `timing-manager`, `records-manager`, `api`,
+`gpu-telemetry-manager`, `server-metrics-manager`, `results-sidecar`,
+`event-bus-proxy`; worker pod: `worker-group-manager` plus worker and
+record-processor containers.
+
+**Immutable spec fields** (a "fix" to any of these means deleting and recreating
+the CR, not patching it): `image`, `imagePullPolicy`, `benchmark`, `resourceMode`,
+`connectionsPerWorker`, `ttlSecondsAfterFinished`, `resultsTtlDays`,
+`keepFailedPods`, `podTemplate`, `scheduling`, `schemaVersion`, `sweep`,
+`multiRun`, `plot`, `variables`, `randomSeed`, `noSweepTable`,
+`skipEndpointCheck`, `failurePolicy`. Only `timeoutSeconds` and `cancel` are
+patchable in place.
+
+## 3. Failed job
+
+```bash
+kubectl get aiperfjob <NAME> -n <NS> -o json | jq '.status | {phase, error, conditions}'
+
+aiperf kube logs <JOB_ID> -n <NS> --container control-plane --tail 50
+aiperf kube debug -j <JOB_ID> -n <NS> --verbose
+```
+
+| `status.error` contains | Root cause | Fix |
+|---|---|---|
+| `preflight` | Cluster validation failed | `aiperf kube preflight -o json`, apply `hints` |
+| `endpoint`, `health check` | Server unreachable *from inside the cluster* | resolve the URL from a pod, not your laptop |
+| `timeout` | Exceeded `spec.timeoutSeconds` | patch it higher, or `0` for no timeout |
+| `ConfigMap`, `size` | Config over the 1 MiB object limit | shrink config / mount data as a file |
+| `image`, `pull` | Image not accessible | check tag and `imagePullSecrets`; on Kind, `kind load` + `imagePullPolicy: Never` |
+| `RBAC`, `forbidden` | Missing permissions | check ServiceAccount, Role, RoleBinding |
+
+## 4. Stuck Pending
+
+```bash
+kubectl get pods -n <NS> -l aiperf.nvidia.com/job-id=<JOB_ID> -o json | jq -c '
+  .items[] | {pod: .metadata.name} + (.status.conditions[]
+  | select(.type=="PodScheduled" and .status=="False") | {reason, message})'
+
+kubectl get nodes -o json | jq -c '.items[] | {node: .metadata.name,
+  cpu: .status.allocatable.cpu, memory: .status.allocatable.memory,
+  gpu: (.status.allocatable["nvidia.com/gpu"] // "0")}'
+```
+
+| Scheduling message | Fix |
+|---|---|
+| `Insufficient cpu` / `Insufficient memory` | lower `--total-workers`; recreate |
+| `nvidia.com/gpu` | no free GPU nodes — wait or add capacity |
+| `didn't match Pod's node affinity/selector` | fix `spec.podTemplate.nodeSelector` (immutable — recreate) |
+| `had untolerated taint` | add `spec.podTemplate.tolerations` (immutable — recreate) |
+| `quota` | namespace ResourceQuota exhausted |
+
+## 5. Kueue not admitted (`Queued`)
+
+The operator stamps `kueue.x-k8s.io/queue-name` (+ `kueue.x-k8s.io/priority-class`)
+on the JobSet and creates it `spec.suspend: true` whenever a queue name resolves
+from `spec.scheduling.queueName` or the operator-side
+`AIPERF_K8S_JOBSET_KUEUE_DEFAULT_QUEUE_NAME`. It does **not** read the namespace
+annotation `kueue.x-k8s.io/default-queue-name` — that only defaults the queue on
+Kueue's side and satisfies operator preflight. While suspended and labelled the
+phase is `Queued`; on admission it walks `Initializing` -> `Running`.
+
+```bash
+kubectl get workloads -n <NS> -o json | jq -c '.items[] | {

+```
+
+- Compare `ClusterQueue.spec.resourceGroups.*.nominalQuota` to what the JobSet
+  requests: each worker pod requests the `AIPERF_K8S_WORKER_POD_CPU` /
+  `_MEMORY` budget (`150m` / `4Gi`) split across its containers.
+- Operator preflight `FAIL` `Kueue LocalQueue '<name>' not found` (or "Kueue is
+  not installed, but LocalQueue '<name>' was explicitly requested"): the queue
+  does not exist in the namespace. `SKIP` means no queue was requested at all.
+  This check is operator-side only; client-side `preflight` omits it.
+- Operator preflight `WARN` `Kueue is installed but no queue configured`: set
+  `--queue-name` / `spec.scheduling.queueName`, or `kubectl annotate namespace
+  <NS> kueue.x-k8s.io/default-queue-name=<queue>`.
+- No preemption despite `priorityClass`: the `WorkloadPriorityClass` value must
+  exceed the admitted workloads', and the ClusterQueue must enable
+  `spec.preemption.reclaimWithinCohort` / `withinClusterQueue`.
+- `spec.scheduling` is immutable — priority cannot be raised on a queued job.
+
+## 6. Stuck Initializing
+
+```bash
+kubectl get pods -n <NS> -l aiperf.nvidia.com/job-id=<JOB_ID> -o json | jq -c '
+  .items[] as $p | $p.status.containerStatuses[]? | select(.ready == false) | {
+    pod: $p.metadata.name, container: .name, restarts: .restartCount,
+    waiting_reason: .state.waiting.reason, waiting_message: .state.waiting.message}'
+```
+
+| Waiting reason | Fix |
+|---|---|
+| `ContainerCreating` | normal, image pulling — wait |
+| `ImagePullBackOff` | bad image or missing pull secret |
+| `CrashLoopBackOff` | §7 |
+| `CreateContainerConfigError` | missing ConfigMap/Secret/volume — read pod events |
+
+Worker pods run a PUB/SUB connection probe that **fails closed**: the pod exits
+so Kubernetes restarts it with a fresh ZMQ context
+(`AIPERF_K8S_JOBSET_WORKER_CONNECTION_PROBE_TIMEOUT` 60 s, backoff limit 20). A
+few early restarts on first deploy are expected, not a bug.
+
+## 7. Crash loop
+
+```bash
+kubectl logs -n <NS> <POD> --previous -c <CONTAINER> --tail=50
+kubectl get pod -n <NS> <POD> -o json | jq -c '.status.containerStatuses[]
+  | select(.lastState.terminated) | {container: .name,
+    exit_code: .lastState.terminated.exitCode, reason: .lastState.terminated.reason,
+    message: .lastState.terminated.message}'
+```
+
+| Exit code | Meaning |
+|---|---|
+| 137 | SIGKILL — node memory pressure / eviction / external kill (§8) |
+| 1 | application error: bad config, missing model, endpoint unreachable |
+| 2 | Python import/syntax error — wrong image version |
+
+## 8. OOM kills
+
+```bash
+kubectl get pod -n <NS> <POD> -o json | jq -c '
+  {limits: [.spec.containers[] | {name, memory: (.resources.limits.memory // "none")}],
+   oom: [.status.containerStatuses[] | select(.lastState.terminated.reason=="OOMKilled") | .name]}'
+kubectl describe node <NODE> | grep -i pressure
+```
+
+`spec.resourceMode` defaults to **`burstable`**: requests, **no limits**. A
+container therefore cannot be cgroup-OOM-killed for exceeding its memory budget
+nor CFS-throttled for exceeding its CPU budget — the `AIPERF_K8S_*` numbers are
+scheduling hints, not ceilings. An `OOMKilled` container is evidence of *node*
+memory pressure or kubelet eviction, not of a too-small `AIPERF_K8S_*_MEMORY`.
+Use `resourceMode: guaranteed` (requests == limits) to enforce the budgets, and
+expect real OOM kills once you do.
+
+Fixes, in order:
+
+1. Lower `spec.connectionsPerWorker` (default `100`) — immutable, recreate.
+2. Lower `spec.benchmark.runtime.workersPerPod` to fan the same cluster-wide
+   worker total across more pods — `spec.benchmark` is immutable, recreate.
+3. Raise `AIPERF_K8S_WORKER_POD_MEMORY` (default `4Gi`) **on the operator**, not
+   in `spec.podTemplate.env` — the operator process renders the JobSet:
+   `kubectl set env -n aiperf-system deploy/aiperf-operator -c operator AIPERF_K8S_WORKER_POD_MEMORY=8Gi`
+
+## 9. Collect results
+
+```bash
+aiperf kube results <JOB_ID> -n <NS>                    # operator PVC (works after pods are gone)
+aiperf kube results <JOB_ID> --from-pods --summary-only # live controller API, kubectl cp fallback
+aiperf kube results <JOB_ID> --output ./artifacts --run <epoch>
+aiperf kube logs <JOB_ID> -n <NS> -o ./triage --ignore-not-found   # <dir>/logs/<pod>.log
+aiperf kube logs <JOB_ID> --container control-plane --follow
+```
+
+Results are harvested only on a **terminal** phase, so "results missing" mid-run
+is correct — use `--from-pods`. On a *successful* run the operator deletes the
+JobSet immediately after harvesting; the 300 s
+`AIPERF_K8S_JOBSET_TTL_SECONDS_AFTER_FINISHED` window is only a fallback for
+failed runs and retried partial harvests. Stream logs during the run; do not
+plan to collect them after. Direct (operator-less) mode keeps pods 8 h
+(`AIPERF_K8S_JOBSET_DIRECT_MODE_TTL_SECONDS`).
+
+```bash
+# profile_export_aiperf.json: top-level keys are metric tags, each an object of
+# {unit, avg, p50, p90, p99, min, max, std, count, sum}.
+jq '{throughput: .request_throughput.avg, latency_avg: .request_latency.avg,
+     latency_p99: .request_latency.p99, ttft_avg: .time_to_first_token.avg,
+     itl_avg: .inter_token_latency.avg, otps: .output_token_throughput.avg,
+     requests: .request_count.avg, errors: .error_request_count.avg,
+     error_rate_pct: .request_error_rate.avg}' ./artifacts/profile_export_aiperf.json
+```
+
+`request_count` counts valid requests only; `completed_request_count` is
+successes + errors. `error_request_count` is omitted entirely on a clean run.
+
+## 10. Stalled benchmark
+
+```bash
+kubectl run aiperf-curl-test --rm -it --restart=Never --image=curlimages/curl -- \
+  curl -s -o /dev/null -w '{"http_code":%{http_code},"time_total":%{time_total}}' <ENDPOINT_URL>/models
+aiperf kube logs <JOB_ID> --container control-plane --tail 30 2>&1 | grep -iE "error|timeout|refused|unreachable"
+```
+
+| Symptom | Fix |
+|---|---|
+| `http_code: 0` / connection refused | wrong endpoint URL or frontend not running; resolve the in-cluster service DNS name |
+| `http_code: 200` but no progress | workers not connecting — check ZMQ in controller logs |
+| curl times out | NetworkPolicy blocking, or the server is still loading the model |
+
+Two more stall causes that produce **zero restarts**:
+
+- **Credit-return channel dead.** Credit dispatch rides a DEALER but credit
+  *returns* ride a separate PUSH/PULL fan-in. That probe fails **open**: on
+  budget expiry (`AIPERF_WORKER_RETURN_PROBE_BUDGET` 30 s,
+  `AIPERF_WORKER_RETURN_PROBE_RETRY_DELAY` 0.1 s) the worker announces itself
+  dispatchable anyway and only logs a warning. Grep worker logs for
+  `Credit-return channel still has no peer` before blaming the endpoint.
+- **CPU starvation of one service.** The records-manager and system-controller
+  request only `75m`. At high request rates a pegged core starves the event
+  loop, heartbeats expire, and the CR freezes mid-phase. Raise
+  `AIPERF_K8S_RECORDS_MANAGER_CPU` on the operator before hunting a logic bug.
+  Widening `AIPERF_K8S_CONTROLLER_HEARTBEAT_EXPIRY_SECONDS` (30 s, must stay at
+  least twice the 10 s interval) hides the starvation instead of fixing it.
+
+## 11. High error rate
+
+```bash
+kubectl get aiperfjob <NAME> -n <NS> -o jsonpath='{.status.liveMetrics.metrics}' | python3 -m json.tool
+```
+
+`request_error_rate` has unit **percent** (`100 * errors / completed`) and is the
+authoritative live error signal; `error_request_count` carries the `ERROR_ONLY`
+flag and is filtered out of `status.liveMetrics` and `/api/metrics`, so its
+absence never means "no errors". The `AIPERF_K8S_DIAGNOSIS_*` thresholds are
+0..1 fractions, so `request_error_rate` is divided by 100 before comparison.
+
+| Error rate | Likely cause |
+|---|---|
+| 5-20% | endpoint overloaded — lower phase concurrency (recreate; `spec.benchmark` is immutable) |
+| 20-50% | model or endpoint errors — check server logs for 500/503 |
+| >50% | endpoint down or misconfigured; verify the model name the server serves |
+| 100% | wrong URL or auth required — fix URL or inject a key via a Secret |
+
+## 12. Preflight JSON
+
+`aiperf kube preflight -o json` (also `-i/--image`, `--image-pull-secret`,
+`--secret`, `-e/--endpoint-url`, `-w/--workers`):
+
+```json
+{"passed": true, "has_warnings": false,
+ "checks": [{"name": "Cluster Connectivity", "status": "pass",
+             "message": "Connected to Kubernetes cluster",
+             "details": [], "hints": [], "duration_ms": 45.2}]}
+```
+
+`status` is one of `pass` (no action), `fail` (blocking — apply `hints[0]`),
+`warn` (review, non-blocking), `skip` (not applicable), `info` (context only).
+`passed` is false iff any check is `fail`; `has_warnings` true iff any is `warn`.
+Gate a script on `jq -e '.passed'` and print the `fail` checks' `hints`.
+
+## 13. Validate JSON
+
+`aiperf kube validate -o json [-s/--strict] <FILE>...` — exits `1` if any file
+fails; `--strict` promotes warnings to errors.
+
+```json
+[{"path": "benchmark.yaml", "passed": true, "errors": [],
+  "warnings": ["Unknown spec fields (did you mean to put these under spec.benchmark?): foo"]}]
+```
+
+## 14. Tunable environment variables
+
+Resource and JobSet variables are read by the process that *renders* the JobSet,
+so set them on the operator deployment (`kubectl set env -n aiperf-system
+deploy/aiperf-operator -c operator KEY=VALUE` — `-c operator` matters, the
+Deployment also runs `results-server` and `dashboard` containers and `set env`
+defaults to all of them); `spec.podTemplate.env` has no effect on
+container resources. Default operator namespace `aiperf-system`; the
+benchmark namespace is whatever you pass to `-n`/`--namespace`.
+
+| Variable | Default | What it does |

+## CLI Flag Routing Under `--config`
+
+A CLI flag passed alongside `--config` MUST either change the resolved config or raise an error naming the flag — never be silently ignored, which for a benchmarking tool means publishing numbers that do not match what was asked for. `CLIConfig` is the source of truth, structurally: `resolve_config` receives a `CLIConfig` and a path and nothing else, so a flag reaches `AIPerfConfig` only by being a field on it. Every field must be classified in `src/aiperf/config/flags/_config_flag_routing.py` as `ROUTED_UNDER_CONFIG`, `UNROUTED_UNDER_CONFIG`, `EXEMPT_FROM_CONFIG_ROUTING`, or one of the conditional sets (`COMPANION_ROUTED`, `MAGIC_LIST_ONLY_UNDER_CONFIG`). Adding a flag without classifying it fails `test_every_cli_config_field_is_classified`; claiming a flag is routed when nothing routes it fails `test_routed_field_never_silently_no_ops`. Prefer routing the flag (check whether a builder already exists) over listing it as unrouted. See [`docs/dev/global-invariants.md`](docs/dev/global-invariants.md) § "CLI flag routing under `--config`".

+## Kubernetes
+
+The Kubernetes operator and CLI layer live in `src/aiperf/operator/`, `src/aiperf/kubernetes/`, and `src/aiperf/cli_commands/kube/`. Key patterns:
+
+- **kopf handlers** — The operator entry point is `src/aiperf/operator/main.py`. All `@kopf.on.*` decorators live there; handler bodies are decorator-free functions in `src/aiperf/operator/handlers/{create,cleanup,completion,lifecycle,monitor}.py`. Raise `kopf.PermanentError` to stop retrying, `kopf.TemporaryError(..., delay=N)` to retry after delay — generic exceptions retry forever. kopf calls handlers with a fixed kwarg set (`body, spec, name, namespace, patch, uid, **_: Any`); these signatures are baselined against `keyword-only-args` because kopf owns the calling convention.
+- **kubernetes_asyncio access** — Always use `async with k8s_client() as api:` from `aiperf.kubernetes.client`; never instantiate `ApiClient()` directly. The helper handles in-cluster-or-kubeconfig fallback and closure.
+- **`aiperf kube` CLI** — Subcommands live in `src/aiperf/cli_commands/kube/` and are registered in `_app.py`. Composite flags (`namespace`, `kubeconfig`, `kube-context`) pass via `KubeManageOptions` from `aiperf.config.kube`.
+- **FastAPI routers** — Two patterns: module-level `router = APIRouter(...)` in `src/aiperf/api/routers/*.py`, and factory `create_xxx_router(deps...) -> APIRouter` in `src/aiperf/operator/routers/jobs.py` when the router closes over live state.
+- **Shellouts** — Always `aiperf.kubernetes.subproc.run_command(...)` / `check_command` / `start_streaming_process` + `terminate_process`; never `asyncio.create_subprocess_exec` directly. 60 s default timeout.
+- **CLI user output** — All kube-CLI output goes through `from aiperf.kubernetes import console as kube_console`; never `print` or `rich.print`. Last-benchmark persistence (`save_last_benchmark`) lives there too — do not roll your own `last_X.json`.
+- **`--output text|json`** — Read-only CLI checks (preflight, validate) expose `Literal["text", "json"]`; in JSON mode, wrap the work in `kube_console.machine_readable_stdout()` and emit via `kube_console.emit_raw(orjson.dumps(..., option=OPT_INDENT_2).decode())`. Result dataclasses own the `to_dict()` schema.
+- **Machine-readable stdout** — Every JSON/YAML payload goes through `kube_console.emit_raw`, never `kube_console.console.print`: Rich hard-wraps lines wider than the resolved console width (80 without a tty) and the break lands mid-token, so a long image reference makes the document unparseable under redirection. `machine_readable_stdout()` retargets the `aiperf.kube` handlers to stderr rather than filtering by level, so no future log record can prepend text to stdout. Human-facing log text (`kube logs`, controller log streaming) stays on `console.print` but must pass `soft_wrap=True`. See `docs/dev/patterns.md` § "Machine-Readable Kube CLI Output Pattern".
+- **Benchmark diagnosis** — `aiperf kube watch` and its `WatchOrchestrator`/`WatchRenderer` split were removed; the salvaged detectors live in `src/aiperf/kubernetes/benchmark_diagnosis.py` and are consumed by `aiperf kube debug`. Tunables are `AIPERF_K8S_DIAGNOSIS_*`.
+- **CRD generator** — Both CRDs (`deploy/helm/aiperf-operator/templates/crd-aiperfjob.yaml` and `crd-aiperfsweep.yaml`) are auto-generated from `AIPerfJobSpec` / `AIPerfSweepSpec` Pydantic models by `tools/generate_crd.py`. Do NOT hand-edit the YAML; run `uv run python tools/generate_crd.py` and verify with `--check`. User-facing validation rule catalog in `docs/kubernetes/crd-validation.md`.
+- **Durable completion claim** — Exactly-once completion work is gated by `await try_claim_completion(...)` in `operator/client_cache.py` — a JSON-patch with a `test` op, so concurrent ticks race atomically on the apiserver. The in-process `_shutdown_sent` set is only a fast path; the CR annotation is authoritative.
+- **Serialized Kubernetes run config** — Every service container reads the same controller-rendered `BenchmarkRun` through `aiperf.kubernetes.serialized_run.read_serialized_run_json`; never independently resolve `CLIConfig` inside `aiperf service`, because seeds, synthesized defaults, and artifact identity must remain identical across pods. Work the resolver chain would have done must therefore ride inside the serialized run or be rendered from it: `artifacts.user_files` is materialized by `aiperf.kubernetes.user_files.materialize_serialized_run_user_files` in the `system_controller` container only (the sole container owning the run directory), against the `BenchmarkRun.run_meta` identity the operator freezes at create time.
+- **Endpoint credential transport** — Serialized `BenchmarkRun` and ConfigMap data remain secret-free. Redact endpoint credentials before persistence, inject them only through Secret-backed `AIPERF_INJECTED_API_KEY`, `AIPERF_INJECTED_HEADERS`, or `AIPERF_INJECTED_ENDPOINT_URLS`, and use `aiperf.common.endpoint_credentials` for validation and rehydration.
+- **Operator metrics** — Wrap **only** kopf reconcile handlers with `@track_handler("name")` (between the `@kopf.*` decorator and the function); never instrument helper functions.
+- **`ServiceRunType.KUBERNETES`** is a generated plugin enum member: it is declared in `src/aiperf/plugin/plugins.yaml` and emitted into `src/aiperf/plugin/enums.py` by `make generate-all-plugin-files`. Never hand-edit `src/aiperf/plugin/enums.py`.
+- **Operator-namespace fallback** — code that needs the chart-default operator namespace MUST import `DEFAULT_OPERATOR_NAMESPACE` from `aiperf.kubernetes.constants`, never hardcode `"aiperf-system"`. Callers with cluster API access should still prefer `find_operator_namespace` (cluster-wide pod-label search).
+- **Dual-channel credit readiness** — credit dispatch rides the DEALER (`CommAddress.CREDIT_ROUTER`) but credit *returns* ride a separate PUSH/PULL fan-in (`CommAddress.CREDIT_RETURN`). A worker MUST pass `probe_return_channel` (`aiperf.workers.return_channel_probe`) before announcing `WorkerDispatchable`, otherwise a dead PUSH side is invisible and every credit routed there stalls until the run timeout. Any new startup signal must not assume the DEALER proves both directions. See `docs/dev/kubernetes-flow.md` § "Dual-Channel Credit Readiness Gate".
+
+For complete implementation details see `docs/dev/kubernetes-flow.md`.
+
+## Parameter Sweeping (Kubernetes)
+
+In-process sweeps and adaptive search are documented in main's `docs/sweeping/` tutorials. The Kubernetes-side path is:
+
+- **Cluster sweep** — `AIPerfSweep` CRD + `operator/handlers/sweep/`. The k8s operator owns the cluster-wide cardinality contract: one `AIPerfJob` (and one controller pod) per variation; each child pod sees a single-config plan. Best for parallelism across nodes and restart durability.
+- **Adaptive outer loop (BO) under the operator** — the sweep-controller pod in `sweep_controller/main.py` instantiates the same `BayesianSearchPlanner` plugin the in-process path uses; the K8s executor creates one `AIPerfJob` per iteration. kopf-side handlers stay BO-agnostic.
+- **Mutual-exclusion gate** — when `AIPERF_OPERATOR_MANAGED=1` is set in a controller pod, `cli_runner._reject_in_process_sweep_under_operator` hard-fails any `plan.is_sweep` to keep both layers from sweeping at once.
+- **Mode dispatch** — `MultiRunOrchestrator.execute` dispatches on `plan.is_adaptive_search`, then on the grid sweep's iteration order (`_plan_iteration_order(plan)` → `SweepMode.REPEATED`/`INDEPENDENT`). The k8s sweep_controller's children-manifest walk in `sweep_controller/main.py` mirrors the same idx → (var,trial) derivation.

 Numeric metric values crossing a serialization boundary or feeding a numerical algorithm must be finite or explicitly `None`. Use `aiperf.common.finite` (`FiniteFloat`, `scrub_non_finite`, `nan_safe_mean`/`std`, `is_finite_value`). Mechanical CI invariants in `tests/unit/property/test_finite_invariants.py` reject new violations and ratchet existing debt to zero via baseline files.

+## CLI Flag Routing Under `--config`
+
+A CLI flag passed alongside `--config` MUST either change the resolved config or raise an error naming the flag — never be silently ignored, which for a benchmarking tool means publishing numbers that do not match what was asked for. `CLIConfig` is the source of truth, structurally: `resolve_config` receives a `CLIConfig` and a path and nothing else, so a flag reaches `AIPerfConfig` only by being a field on it. Every field must be classified in `src/aiperf/config/flags/_config_flag_routing.py` as `ROUTED_UNDER_CONFIG`, `UNROUTED_UNDER_CONFIG`, `EXEMPT_FROM_CONFIG_ROUTING`, or one of the conditional sets (`COMPANION_ROUTED`, `MAGIC_LIST_ONLY_UNDER_CONFIG`). Adding a flag without classifying it fails `test_every_cli_config_field_is_classified`; claiming a flag is routed when nothing routes it fails `test_routed_field_never_silently_no_ops`. Prefer routing the flag (check whether a builder already exists) over listing it as unrouted. See [`docs/dev/global-invariants.md`](docs/dev/global-invariants.md) § "CLI flag routing under `--config`".

+## Kubernetes
+
+The Kubernetes operator and CLI layer live in `src/aiperf/operator/`, `src/aiperf/kubernetes/`, and `src/aiperf/cli_commands/kube/`. Key patterns:
+
+- **kopf handlers** — The operator entry point is `src/aiperf/operator/main.py`. All `@kopf.on.*` decorators live there; handler bodies are decorator-free functions in `src/aiperf/operator/handlers/{create,cleanup,completion,lifecycle,monitor}.py`. Raise `kopf.PermanentError` to stop retrying, `kopf.TemporaryError(..., delay=N)` to retry after delay — generic exceptions retry forever. kopf calls handlers with a fixed kwarg set (`body, spec, name, namespace, patch, uid, **_: Any`); these signatures are baselined against `keyword-only-args` because kopf owns the calling convention.
+- **kubernetes_asyncio access** — Always use `async with k8s_client() as api:` from `aiperf.kubernetes.client`; never instantiate `ApiClient()` directly. The helper handles in-cluster-or-kubeconfig fallback and closure.
+- **`aiperf kube` CLI** — Subcommands live in `src/aiperf/cli_commands/kube/` and are registered in `_app.py`. Composite flags (`namespace`, `kubeconfig`, `kube-context`) pass via `KubeManageOptions` from `aiperf.config.kube`.
+- **FastAPI routers** — Two patterns: module-level `router = APIRouter(...)` in `src/aiperf/api/routers/*.py`, and factory `create_xxx_router(deps...) -> APIRouter` in `src/aiperf/operator/routers/jobs.py` when the router closes over live state.
+- **Shellouts** — Always `aiperf.kubernetes.subproc.run_command(...)` / `check_command` / `start_streaming_process` + `terminate_process`; never `asyncio.create_subprocess_exec` directly. 60 s default timeout.
+- **CLI user output** — All kube-CLI output goes through `from aiperf.kubernetes import console as kube_console`; never `print` or `rich.print`. Last-benchmark persistence (`save_last_benchmark`) lives there too — do not roll your own `last_X.json`.
+- **`--output text|json`** — Read-only CLI checks (preflight, validate) expose `Literal["text", "json"]`; in JSON mode, wrap the work in `kube_console.machine_readable_stdout()` and emit via `kube_console.emit_raw(orjson.dumps(..., option=OPT_INDENT_2).decode())`. Result dataclasses own the `to_dict()` schema.
+- **Machine-readable stdout** — Every JSON/YAML payload goes through `kube_console.emit_raw`, never `kube_console.console.print`: Rich hard-wraps lines wider than the resolved console width (80 without a tty) and the break lands mid-token, so a long image reference makes the document unparseable under redirection. `machine_readable_stdout()` retargets the `aiperf.kube` handlers to stderr rather than filtering by level, so no future log record can prepend text to stdout. Human-facing log text (`kube logs`, controller log streaming) stays on `console.print` but must pass `soft_wrap=True`. See `docs/dev/patterns.md` § "Machine-Readable Kube CLI Output Pattern".
+- **Benchmark diagnosis** — `aiperf kube watch` and its `WatchOrchestrator`/`WatchRenderer` split were removed; the salvaged detectors live in `src/aiperf/kubernetes/benchmark_diagnosis.py` and are consumed by `aiperf kube debug`. Tunables are `AIPERF_K8S_DIAGNOSIS_*`.
+- **CRD generator** — Both CRDs (`deploy/helm/aiperf-operator/templates/crd-aiperfjob.yaml` and `crd-aiperfsweep.yaml`) are auto-generated from `AIPerfJobSpec` / `AIPerfSweepSpec` Pydantic models by `tools/generate_crd.py`. Do NOT hand-edit the YAML; run `uv run python tools/generate_crd.py` and verify with `--check`. User-facing validation rule catalog in `docs/kubernetes/crd-validation.md`.
+- **Durable completion claim** — Exactly-once completion work is gated by `await try_claim_completion(...)` in `operator/client_cache.py` — a JSON-patch with a `test` op, so concurrent ticks race atomically on the apiserver. The in-process `_shutdown_sent` set is only a fast path; the CR annotation is authoritative.
+- **Serialized Kubernetes run config** — Every service container reads the same controller-rendered `BenchmarkRun` through `aiperf.kubernetes.serialized_run.read_serialized_run_json`; never independently resolve `CLIConfig` inside `aiperf service`, because seeds, synthesized defaults, and artifact identity must remain identical across pods. Work the resolver chain would have done must therefore ride inside the serialized run or be rendered from it: `artifacts.user_files` is materialized by `aiperf.kubernetes.user_files.materialize_serialized_run_user_files` in the `system_controller` container only (the sole container owning the run directory), against the `BenchmarkRun.run_meta` identity the operator freezes at create time.
+- **Endpoint credential transport** — Serialized `BenchmarkRun` and ConfigMap data remain secret-free. Redact endpoint credentials before persistence, inject them only through Secret-backed `AIPERF_INJECTED_API_KEY`, `AIPERF_INJECTED_HEADERS`, or `AIPERF_INJECTED_ENDPOINT_URLS`, and use `aiperf.common.endpoint_credentials` for validation and rehydration.
+- **Operator metrics** — Wrap **only** kopf reconcile handlers with `@track_handler("name")` (between the `@kopf.*` decorator and the function); never instrument helper functions.
+- **`ServiceRunType.KUBERNETES`** is a generated plugin enum member: it is declared in `src/aiperf/plugin/plugins.yaml` and emitted into `src/aiperf/plugin/enums.py` by `make generate-all-plugin-files`. Never hand-edit `src/aiperf/plugin/enums.py`.
+- **Operator-namespace fallback** — code that needs the chart-default operator namespace MUST import `DEFAULT_OPERATOR_NAMESPACE` from `aiperf.kubernetes.constants`, never hardcode `"aiperf-system"`. Callers with cluster API access should still prefer `find_operator_namespace` (cluster-wide pod-label search).
+- **Dual-channel credit readiness** — credit dispatch rides the DEALER (`CommAddress.CREDIT_ROUTER`) but credit *returns* ride a separate PUSH/PULL fan-in (`CommAddress.CREDIT_RETURN`). A worker MUST pass `probe_return_channel` (`aiperf.workers.return_channel_probe`) before announcing `WorkerDispatchable`, otherwise a dead PUSH side is invisible and every credit routed there stalls until the run timeout. Any new startup signal must not assume the DEALER proves both directions. See `docs/dev/kubernetes-flow.md` § "Dual-Channel Credit Readiness Gate".
+
+For complete implementation details see `docs/dev/kubernetes-flow.md`.
+
+## Parameter Sweeping (Kubernetes)
+
+In-process sweeps and adaptive search are documented in main's `docs/sweeping/` tutorials. The Kubernetes-side path is:
+
+- **Cluster sweep** — `AIPerfSweep` CRD + `operator/handlers/sweep/`. The k8s operator owns the cluster-wide cardinality contract: one `AIPerfJob` (and one controller pod) per variation; each child pod sees a single-config plan. Best for parallelism across nodes and restart durability.
+- **Adaptive outer loop (BO) under the operator** — the sweep-controller pod in `sweep_controller/main.py` instantiates the same `BayesianSearchPlanner` plugin the in-process path uses; the K8s executor creates one `AIPerfJob` per iteration. kopf-side handlers stay BO-agnostic.
+- **Mutual-exclusion gate** — when `AIPERF_OPERATOR_MANAGED=1` is set in a controller pod, `cli_runner._reject_in_process_sweep_under_operator` hard-fails any `plan.is_sweep` to keep both layers from sweeping at once.
+- **Mode dispatch** — `MultiRunOrchestrator.execute` dispatches on `plan.is_adaptive_search`, then on the grid sweep's iteration order (`_plan_iteration_order(plan)` → `SweepMode.REPEATED`/`INDEPENDENT`). The k8s sweep_controller's children-manifest walk in `sweep_controller/main.py` mirrors the same idx → (var,trial) derivation.

 Numeric metric values crossing a serialization boundary or feeding a numerical algorithm must be finite or explicitly `None`. Use `aiperf.common.finite` (`FiniteFloat`, `scrub_non_finite`, `nan_safe_mean`/`std`, `is_finite_value`). Mechanical CI invariants in `tests/unit/property/test_finite_invariants.py` reject new violations and ratchet existing debt to zero via baseline files.

+## CLI Flag Routing Under `--config`
+
+A CLI flag passed alongside `--config` MUST either change the resolved config or raise an error naming the flag — never be silently ignored, which for a benchmarking tool means publishing numbers that do not match what was asked for. `CLIConfig` is the source of truth, structurally: `resolve_config` receives a `CLIConfig` and a path and nothing else, so a flag reaches `AIPerfConfig` only by being a field on it. Every field must be classified in `src/aiperf/config/flags/_config_flag_routing.py` as `ROUTED_UNDER_CONFIG`, `UNROUTED_UNDER_CONFIG`, `EXEMPT_FROM_CONFIG_ROUTING`, or one of the conditional sets (`COMPANION_ROUTED`, `MAGIC_LIST_ONLY_UNDER_CONFIG`). Adding a flag without classifying it fails `test_every_cli_config_field_is_classified`; claiming a flag is routed when nothing routes it fails `test_routed_field_never_silently_no_ops`. Prefer routing the flag (check whether a builder already exists) over listing it as unrouted. See [`docs/dev/global-invariants.md`](docs/dev/global-invariants.md) § "CLI flag routing under `--config`".

+## Kubernetes
+
+The Kubernetes operator and CLI layer live in `src/aiperf/operator/`, `src/aiperf/kubernetes/`, and `src/aiperf/cli_commands/kube/`. Key patterns:
+
+- **kopf handlers** — The operator entry point is `src/aiperf/operator/main.py`. All `@kopf.on.*` decorators live there; handler bodies are decorator-free functions in `src/aiperf/operator/handlers/{create,cleanup,completion,lifecycle,monitor}.py`. Raise `kopf.PermanentError` to stop retrying, `kopf.TemporaryError(..., delay=N)` to retry after delay — generic exceptions retry forever. kopf calls handlers with a fixed kwarg set (`body, spec, name, namespace, patch, uid, **_: Any`); these signatures are baselined against `keyword-only-args` because kopf owns the calling convention.
+- **kubernetes_asyncio access** — Always use `async with k8s_client() as api:` from `aiperf.kubernetes.client`; never instantiate `ApiClient()` directly. The helper handles in-cluster-or-kubeconfig fallback and closure.
+- **`aiperf kube` CLI** — Subcommands live in `src/aiperf/cli_commands/kube/` and are registered in `_app.py`. Composite flags (`namespace`, `kubeconfig`, `kube-context`) pass via `KubeManageOptions` from `aiperf.config.kube`.
+- **FastAPI routers** — Two patterns: module-level `router = APIRouter(...)` in `src/aiperf/api/routers/*.py`, and factory `create_xxx_router(deps...) -> APIRouter` in `src/aiperf/operator/routers/jobs.py` when the router closes over live state.
+- **Shellouts** — Always `aiperf.kubernetes.subproc.run_command(...)` / `check_command` / `start_streaming_process` + `terminate_process`; never `asyncio.create_subprocess_exec` directly. 60 s default timeout.
+- **CLI user output** — All kube-CLI output goes through `from aiperf.kubernetes import console as kube_console`; never `print` or `rich.print`. Last-benchmark persistence (`save_last_benchmark`) lives there too — do not roll your own `last_X.json`.
+- **`--output text|json`** — Read-only CLI checks (preflight, validate) expose `Literal["text", "json"]`; in JSON mode, wrap the work in `kube_console.machine_readable_stdout()` and emit via `kube_console.emit_raw(orjson.dumps(..., option=OPT_INDENT_2).decode())`. Result dataclasses own the `to_dict()` schema.
+- **Machine-readable stdout** — Every JSON/YAML payload goes through `kube_console.emit_raw`, never `kube_console.console.print`: Rich hard-wraps lines wider than the resolved console width (80 without a tty) and the break lands mid-token, so a long image reference makes the document unparseable under redirection. `machine_readable_stdout()` retargets the `aiperf.kube` handlers to stderr rather than filtering by level, so no future log record can prepend text to stdout. Human-facing log text (`kube logs`, controller log streaming) stays on `console.print` but must pass `soft_wrap=True`. See `docs/dev/patterns.md` § "Machine-Readable Kube CLI Output Pattern".
+- **Benchmark diagnosis** — `aiperf kube watch` and its `WatchOrchestrator`/`WatchRenderer` split were removed; the salvaged detectors live in `src/aiperf/kubernetes/benchmark_diagnosis.py` and are consumed by `aiperf kube debug`. Tunables are `AIPERF_K8S_DIAGNOSIS_*`.
+- **CRD generator** — Both CRDs (`deploy/helm/aiperf-operator/templates/crd-aiperfjob.yaml` and `crd-aiperfsweep.yaml`) are auto-generated from `AIPerfJobSpec` / `AIPerfSweepSpec` Pydantic models by `tools/generate_crd.py`. Do NOT hand-edit the YAML; run `uv run python tools/generate_crd.py` and verify with `--check`. User-facing validation rule catalog in `docs/kubernetes/crd-validation.md`.
+- **Durable completion claim** — Exactly-once completion work is gated by `await try_claim_completion(...)` in `operator/client_cache.py` — a JSON-patch with a `test` op, so concurrent ticks race atomically on the apiserver. The in-process `_shutdown_sent` set is only a fast path; the CR annotation is authoritative.
+- **Serialized Kubernetes run config** — Every service container reads the same controller-rendered `BenchmarkRun` through `aiperf.kubernetes.serialized_run.read_serialized_run_json`; never independently resolve `CLIConfig` inside `aiperf service`, because seeds, synthesized defaults, and artifact identity must remain identical across pods. Work the resolver chain would have done must therefore ride inside the serialized run or be rendered from it: `artifacts.user_files` is materialized by `aiperf.kubernetes.user_files.materialize_serialized_run_user_files` in the `system_controller` container only (the sole container owning the run directory), against the `BenchmarkRun.run_meta` identity the operator freezes at create time.
+- **Endpoint credential transport** — Serialized `BenchmarkRun` and ConfigMap data remain secret-free. Redact endpoint credentials before persistence, inject them only through Secret-backed `AIPERF_INJECTED_API_KEY`, `AIPERF_INJECTED_HEADERS`, or `AIPERF_INJECTED_ENDPOINT_URLS`, and use `aiperf.common.endpoint_credentials` for validation and rehydration.
+- **Operator metrics** — Wrap **only** kopf reconcile handlers with `@track_handler("name")` (between the `@kopf.*` decorator and the function); never instrument helper functions.
+- **`ServiceRunType.KUBERNETES`** is a generated plugin enum member: it is declared in `src/aiperf/plugin/plugins.yaml` and emitted into `src/aiperf/plugin/enums.py` by `make generate-all-plugin-files`. Never hand-edit `src/aiperf/plugin/enums.py`.
+- **Operator-namespace fallback** — code that needs the chart-default operator namespace MUST import `DEFAULT_OPERATOR_NAMESPACE` from `aiperf.kubernetes.constants`, never hardcode `"aiperf-system"`. Callers with cluster API access should still prefer `find_operator_namespace` (cluster-wide pod-label search).
+- **Dual-channel credit readiness** — credit dispatch rides the DEALER (`CommAddress.CREDIT_ROUTER`) but credit *returns* ride a separate PUSH/PULL fan-in (`CommAddress.CREDIT_RETURN`). A worker MUST pass `probe_return_channel` (`aiperf.workers.return_channel_probe`) before announcing `WorkerDispatchable`, otherwise a dead PUSH side is invisible and every credit routed there stalls until the run timeout. Any new startup signal must not assume the DEALER proves both directions. See `docs/dev/kubernetes-flow.md` § "Dual-Channel Credit Readiness Gate".
+
+For complete implementation details see `docs/dev/kubernetes-flow.md`.
+
+## Parameter Sweeping (Kubernetes)
+
+In-process sweeps and adaptive search are documented in main's `docs/sweeping/` tutorials. The Kubernetes-side path is:
+
+- **Cluster sweep** — `AIPerfSweep` CRD + `operator/handlers/sweep/`. The k8s operator owns the cluster-wide cardinality contract: one `AIPerfJob` (and one controller pod) per variation; each child pod sees a single-config plan. Best for parallelism across nodes and restart durability.
+- **Adaptive outer loop (BO) under the operator** — the sweep-controller pod in `sweep_controller/main.py` instantiates the same `BayesianSearchPlanner` plugin the in-process path uses; the K8s executor creates one `AIPerfJob` per iteration. kopf-side handlers stay BO-agnostic.
+- **Mutual-exclusion gate** — when `AIPERF_OPERATOR_MANAGED=1` is set in a controller pod, `cli_runner._reject_in_process_sweep_under_operator` hard-fails any `plan.is_sweep` to keep both layers from sweeping at once.
+- **Mode dispatch** — `MultiRunOrchestrator.execute` dispatches on `plan.is_adaptive_search`, then on the grid sweep's iteration order (`_plan_iteration_order(plan)` → `SweepMode.REPEATED`/`INDEPENDENT`). The k8s sweep_controller's children-manifest walk in `sweep_controller/main.py` mirrors the same idx → (var,trial) derivation.

+- **Control channel** — commands, registration, heartbeats, and lifecycle status ride a DEALER/ROUTER socket at `CommAddress.CONTROL` carrying `msgspec` structs from `aiperf.common.control_structs`, not the pub/sub event bus. `@on_command` handlers take a `Command` and decode `message.payload` with `orjson`.

 Numeric metric values crossing a serialization boundary or feeding a numerical algorithm must be finite or explicitly `None`. Use `aiperf.common.finite` (`FiniteFloat`, `scrub_non_finite`, `nan_safe_mean`/`std`, `is_finite_value`). Mechanical CI invariants in `tests/unit/property/test_finite_invariants.py` reject new violations and ratchet existing debt to zero via baseline files.

+## CLI Flag Routing Under `--config`
+
+A CLI flag passed alongside `--config` MUST either change the resolved config or raise an error naming the flag — never be silently ignored, which for a benchmarking tool means publishing numbers that do not match what was asked for. `CLIConfig` is the source of truth, structurally: `resolve_config` receives a `CLIConfig` and a path and nothing else, so a flag reaches `AIPerfConfig` only by being a field on it. Every field must be classified in `src/aiperf/config/flags/_config_flag_routing.py` as `ROUTED_UNDER_CONFIG`, `UNROUTED_UNDER_CONFIG`, `EXEMPT_FROM_CONFIG_ROUTING`, or one of the conditional sets (`COMPANION_ROUTED`, `MAGIC_LIST_ONLY_UNDER_CONFIG`). Adding a flag without classifying it fails `test_every_cli_config_field_is_classified`; claiming a flag is routed when nothing routes it fails `test_routed_field_never_silently_no_ops`. Prefer routing the flag (check whether a builder already exists) over listing it as unrouted. See [`docs/dev/global-invariants.md`](docs/dev/global-invariants.md) § "CLI flag routing under `--config`".

+## Kubernetes
+
+The Kubernetes operator and CLI layer live in `src/aiperf/operator/`, `src/aiperf/kubernetes/`, and `src/aiperf/cli_commands/kube/`. Key patterns:
+
+- **kopf handlers** — The operator entry point is `src/aiperf/operator/main.py`. All `@kopf.on.*` decorators live there; handler bodies are decorator-free functions in `src/aiperf/operator/handlers/{create,cleanup,completion,lifecycle,monitor}.py`. Raise `kopf.PermanentError` to stop retrying, `kopf.TemporaryError(..., delay=N)` to retry after delay — generic exceptions retry forever. kopf calls handlers with a fixed kwarg set (`body, spec, name, namespace, patch, uid, **_: Any`); these signatures are baselined against `keyword-only-args` because kopf owns the calling convention.
+- **kubernetes_asyncio access** — Always use `async with k8s_client() as api:` from `aiperf.kubernetes.client`; never instantiate `ApiClient()` directly. The helper handles in-cluster-or-kubeconfig fallback and closure.
+- **`aiperf kube` CLI** — Subcommands live in `src/aiperf/cli_commands/kube/` and are registered in `_app.py`. Composite flags (`namespace`, `kubeconfig`, `kube-context`) pass via `KubeManageOptions` from `aiperf.config.kube`.
+- **FastAPI routers** — Two patterns: module-level `router = APIRouter(...)` in `src/aiperf/api/routers/*.py`, and factory `create_xxx_router(deps...) -> APIRouter` in `src/aiperf/operator/routers/jobs.py` when the router closes over live state.
+- **Shellouts** — Always `aiperf.kubernetes.subproc.run_command(...)` / `check_command` / `start_streaming_process` + `terminate_process`; never `asyncio.create_subprocess_exec` directly. 60 s default timeout.
+- **CLI user output** — All kube-CLI output goes through `from aiperf.kubernetes import console as kube_console`; never `print` or `rich.print`. Last-benchmark persistence (`save_last_benchmark`) lives there too — do not roll your own `last_X.json`.
+- **`--output text|json`** — Read-only CLI checks (preflight, validate) expose `Literal["text", "json"]`; in JSON mode, wrap the work in `kube_console.machine_readable_stdout()` and emit via `kube_console.emit_raw(orjson.dumps(..., option=OPT_INDENT_2).decode())`. Result dataclasses own the `to_dict()` schema.
+- **Machine-readable stdout** — Every JSON/YAML payload goes through `kube_console.emit_raw`, never `kube_console.console.print`: Rich hard-wraps lines wider than the resolved console width (80 without a tty) and the break lands mid-token, so a long image reference makes the document unparseable under redirection. `machine_readable_stdout()` retargets the `aiperf.kube` handlers to stderr rather than filtering by level, so no future log record can prepend text to stdout. Human-facing log text (`kube logs`, controller log streaming) stays on `console.print` but must pass `soft_wrap=True`. See `docs/dev/patterns.md` § "Machine-Readable Kube CLI Output Pattern".
+- **Benchmark diagnosis** — `aiperf kube watch` and its `WatchOrchestrator`/`WatchRenderer` split were removed; the salvaged detectors live in `src/aiperf/kubernetes/benchmark_diagnosis.py` and are consumed by `aiperf kube debug`. Tunables are `AIPERF_K8S_DIAGNOSIS_*`.
+- **CRD generator** — Both CRDs (`deploy/helm/aiperf-operator/templates/crd-aiperfjob.yaml` and `crd-aiperfsweep.yaml`) are auto-generated from `AIPerfJobSpec` / `AIPerfSweepSpec` Pydantic models by `tools/generate_crd.py`. Do NOT hand-edit the YAML; run `uv run python tools/generate_crd.py` and verify with `--check`. User-facing validation rule catalog in `docs/kubernetes/crd-validation.md`.
+- **Durable completion claim** — Exactly-once completion work is gated by `await try_claim_completion(...)` in `operator/client_cache.py` — a JSON-patch with a `test` op, so concurrent ticks race atomically on the apiserver. The in-process `_shutdown_sent` set is only a fast path; the CR annotation is authoritative.
+- **Serialized Kubernetes run config** — Every service container reads the same controller-rendered `BenchmarkRun` through `aiperf.kubernetes.serialized_run.read_serialized_run_json`; never independently resolve `CLIConfig` inside `aiperf service`, because seeds, synthesized defaults, and artifact identity must remain identical across pods. Work the resolver chain would have done must therefore ride inside the serialized run or be rendered from it: `artifacts.user_files` is materialized by `aiperf.kubernetes.user_files.materialize_serialized_run_user_files` in the `system_controller` container only (the sole container owning the run directory), against the `BenchmarkRun.run_meta` identity the operator freezes at create time.
+- **Endpoint credential transport** — Serialized `BenchmarkRun` and ConfigMap data remain secret-free. Redact endpoint credentials before persistence, inject them only through Secret-backed `AIPERF_INJECTED_API_KEY`, `AIPERF_INJECTED_HEADERS`, or `AIPERF_INJECTED_ENDPOINT_URLS`, and use `aiperf.common.endpoint_credentials` for validation and rehydration.
+- **Operator metrics** — Wrap **only** kopf reconcile handlers with `@track_handler("name")` (between the `@kopf.*` decorator and the function); never instrument helper functions.
+- **`ServiceRunType.KUBERNETES`** is a generated plugin enum member: it is declared in `src/aiperf/plugin/plugins.yaml` and emitted into `src/aiperf/plugin/enums.py` by `make generate-all-plugin-files`. Never hand-edit `src/aiperf/plugin/enums.py`.
+- **Operator-namespace fallback** — code that needs the chart-default operator namespace MUST import `DEFAULT_OPERATOR_NAMESPACE` from `aiperf.kubernetes.constants`, never hardcode `"aiperf-system"`. Callers with cluster API access should still prefer `find_operator_namespace` (cluster-wide pod-label search).
+- **Dual-channel credit readiness** — credit dispatch rides the DEALER (`CommAddress.CREDIT_ROUTER`) but credit *returns* ride a separate PUSH/PULL fan-in (`CommAddress.CREDIT_RETURN`). A worker MUST pass `probe_return_channel` (`aiperf.workers.return_channel_probe`) before announcing `WorkerDispatchable`, otherwise a dead PUSH side is invisible and every credit routed there stalls until the run timeout. Any new startup signal must not assume the DEALER proves both directions. See `docs/dev/kubernetes-flow.md` § "Dual-Channel Credit Readiness Gate".
+
+For complete implementation details see `docs/dev/kubernetes-flow.md`.
+
+## Parameter Sweeping (Kubernetes)
+
+In-process sweeps and adaptive search are documented in main's `docs/sweeping/` tutorials. The Kubernetes-side path is:
+
+- **Cluster sweep** — `AIPerfSweep` CRD + `operator/handlers/sweep/`. The k8s operator owns the cluster-wide cardinality contract: one `AIPerfJob` (and one controller pod) per variation; each child pod sees a single-config plan. Best for parallelism across nodes and restart durability.
+- **Adaptive outer loop (BO) under the operator** — the sweep-controller pod in `sweep_controller/main.py` instantiates the same `BayesianSearchPlanner` plugin the in-process path uses; the K8s executor creates one `AIPerfJob` per iteration. kopf-side handlers stay BO-agnostic.
+- **Mutual-exclusion gate** — when `AIPERF_OPERATOR_MANAGED=1` is set in a controller pod, `cli_runner._reject_in_process_sweep_under_operator` hard-fails any `plan.is_sweep` to keep both layers from sweeping at once.
+- **Mode dispatch** — `MultiRunOrchestrator.execute` dispatches on `plan.is_adaptive_search`, then on the grid sweep's iteration order (`_plan_iteration_order(plan)` → `SweepMode.REPEATED`/`INDEPENDENT`). The k8s sweep_controller's children-manifest walk in `sweep_controller/main.py` mirrors the same idx → (var,trial) derivation.

 Please note, the skill does run `aiperf` and utilizes a mock server. If you are working on a laptop or personal work station, be aware that this may slow down your computer during review.
 
+#### Kubernetes
+
+The `aiperf-kube-*` skills cover the Kubernetes path and are grounded in
+[`docs/kubernetes/`](docs/kubernetes/). Start with `aiperf-kube-run`, which links
+out to the other three. They quote CLI flags, container defaults, and Helm values
+as literals, so they can go stale when those change; the pack ships a verifier
+that checks every one of them against the live CLI and the working tree:

+```bash
+uv run python .agents/skills/aiperf-kube-run/verify_pack.py
+```
+
+Run it after changing an `aiperf kube` flag, a `AIPERF_K8S_*` default, or
+`deploy/helm/aiperf-operator/values.yaml`, and update the skill text when it fails.

+# aiperf-operator Helm chart
+
+Deploys the AIPerf Kubernetes operator, its two CRDs (`aiperfjobs.aiperf.nvidia.com` and `aiperfsweeps.aiperf.nvidia.com`), the results-server sidecar, an optional dashboard sidecar, and optional RBAC / storage / ingress / NetworkPolicy / Kueue / ServiceMonitor resources.
+
+Both CRD templates are generated from the `AIPerfJobSpec` / `AIPerfSweepSpec` Pydantic models by `tools/generate_crd.py`. Do not hand-edit `templates/crd-aiperfjob.yaml` or `templates/crd-aiperfsweep.yaml`.
+
+```bash
+helm install aiperf-operator deploy/helm/aiperf-operator \
+  --namespace aiperf-system --create-namespace
+```
+
+After install, submit a benchmark with `AIPerfJob` — see [`templates/NOTES.txt`](./templates/NOTES.txt) or [`docs/kubernetes/getting-started.md`](../../../docs/kubernetes/getting-started.md).
+
+Benchmarks run in the release namespace. The chart creates no `Namespace` objects of its own; it provisions benchmark RBAC in the namespace you install into, plus any already-existing namespaces you list in `benchmarkRbacNamespaces`.
+
+## Values
+
+All values are documented inline in [`values.yaml`](./values.yaml). Common overrides:
+
+| Value | Purpose |
+|---|---|
+| `image.repository` / `image.tag` | Operator image (defaults to `nvcr.io/nvidia/aiperf:<appVersion>`). Override `image.tag` for dev builds — it automatically propagates to the CRD schema default for `spec.image`. |
+| `defaults.image` | Override the benchmark-pod image independently of the operator image. Leave empty to derive from `image.repository`/`image.tag`. |
+| `operator.watchNamespaces` | Namespaces to watch for `AIPerfJob` and `AIPerfSweep` CRs (`--namespace=<ns>` per entry). Empty list (default) passes `--all-namespaces`. |
+| `benchmarkRbacNamespaces` | Extra, already-existing namespaces to provision benchmark RBAC in, beyond the release namespace (e.g. multi-team setups). The chart does not create them. |
+| `serverMetricsDiscoveryNamespaces` | Existing inference namespaces (e.g. a Dynamo deployment) where benchmark pods get read-only `pods` RBAC for cross-namespace server-metrics endpoint discovery. A plain string entry binds the benchmark namespaces' `default` ServiceAccount; use `{namespace, serviceAccounts: [...]}` to bind custom ServiceAccounts (`podTemplate.serviceAccountName`). Namespaces are not created by the chart. |
+| `serviceAccount.create` / `.name` | Default `create: true` provisions the operator ServiceAccount and binds it to the chart's ClusterRole. With `create: false` the chart binds no RBAC, so `serviceAccount.name` becomes **required** — it must name a pre-provisioned account already bound to the operator's ClusterRole. The render fails otherwise, rather than silently using the namespace `default` account, which has no operator permissions. |
+| `storage.enabled` | Default `true`: back the results volume with a `PersistentVolumeClaim` so benchmark results survive operator restarts. Set `false` to fall back to `emptyDir` (ephemeral, useful for clusters with no default `StorageClass`). |
+| `kueue.createQueues` | Chart-manage `ResourceFlavor` / `ClusterQueue` / `LocalQueue`. Gated on the `kueue.x-k8s.io/v1beta1` API being present. |
+| `serviceMonitor.enabled` | Create a Prometheus Operator `ServiceMonitor`. Gated on `monitoring.coreos.com/v1`. |
+| `ingress.enabled` | Expose the results-server HTTP API outside the cluster. |
+| `networkPolicy.enabled` | Lock down the operator pod's ingress/egress. |
+| `dashboard.enabled` | Add the Plotly Dash sidecar (off by default). results-server reverse-proxies `/dashboard/*` to it on `dashboard.port` (8082). |
+| `tests.enabled` | Default `true`: render the `helm test` hook pods plus the dedicated test ServiceAccount, Role, RoleBinding, ClusterRole, and ClusterRoleBinding. Set `false` to render none of them — this is the only way to make the chart emit zero cluster-scoped RBAC, because the CRD check reads cluster-scoped resources. Deliberately independent of `rbac.create`; see [`helm test` and cluster-scoped RBAC](#helm-test-and-cluster-scoped-rbac). |
+| `tests.image.repository` / `.tag` | Image used by `helm test` hook pods. Defaults to `alpine/k8s:1.33.11` (provides `kubectl` + `curl`). |
+
+## Release name guidance
+
+The default fullname helper produces `<release>-<chart>`, and individual resources append a role suffix (`-results`, `-benchmark`, `-tests`, …). Installing with release name `aiperf` yields resource names like `aiperf-aiperf-operator-…`. Three ways to avoid the duplicated prefix:
+
+1. Use `aiperf-operator` as the release name (the helper collapses when release contains the chart name):
+   ```bash
+   helm install aiperf-operator deploy/helm/aiperf-operator -n aiperf-system
+   ```
+2. Set `fullnameOverride` for full control:
+   ```bash
+   helm install aiperf deploy/helm/aiperf-operator -n aiperf-system \
+     --set fullnameOverride=aiperf-operator
+   ```
+3. Set `nameOverride` to change just the chart-name portion (rarely what you want).
+
+## Uninstall + reinstall behavior
+
+These resources are annotated `helm.sh/resource-policy: keep` and intentionally survive `helm uninstall`:
+
+- `CustomResourceDefinition aiperfjobs.aiperf.nvidia.com`
+- `CustomResourceDefinition aiperfsweeps.aiperf.nvidia.com`
+
+This is so a `helm uninstall` while a benchmark is still running does not drop the live CRs. Helm leaves its release-metadata annotations (`meta.helm.sh/release-name`, `meta.helm.sh/release-namespace`) on them — which has a concrete side effect:
+
+**Re-installing under a different release name will fail** with `invalid ownership metadata` on the preserved CRDs. If you need to switch release names, clean up manually first:
+
+```bash
+kubectl delete crd aiperfjobs.aiperf.nvidia.com      # only if no live AIPerfJob CRs
+kubectl delete crd aiperfsweeps.aiperf.nvidia.com    # only if no live AIPerfSweep CRs
+# then install under the new release name
+```
+
+Re-installing under the **same** release name works without any cleanup.
+
+## Running `helm test`
+
+```bash
+helm test aiperf-operator -n aiperf-system --logs
+```
+
+Two hook pods run:
+- `…-test-crd` — verifies both CRDs are registered and serving `v1alpha1`.
+- `…-test-health` — resolves the operator pod IP, hits kopf's `/healthz` on 8080, then the results-server's `/api/v1/jobs` on `resultsServer.port`.
+
+Both use a dedicated test `ServiceAccount` (`…-tests`) with minimal RBAC: `get` on the two AIPerf CRDs (name-restricted) and `get`/`list` on pods in the release namespace. The test SA and RBAC are ordinary chart-managed resources, not test-phase hooks, so `helm test --logs` only iterates the actual Pod hooks; they are removed by `helm uninstall`.
+
+Hook pods carry only `helm.sh/hook-delete-policy: before-hook-creation`, so they persist after the run and are deleted at the start of the next `helm test`. Use `helm test … --logs` to stream output, or `kubectl logs` the `Completed` / `Failed` pods any time before the next test run.
+
+### `helm test` and cluster-scoped RBAC
+
+`rbac.create=false` suppresses the operator's own `ClusterRole` and `ClusterRoleBinding`, but not the test hooks' — the `…-tests` `ClusterRole`/`ClusterRoleBinding` still render, because pre-provisioning operator RBAC out-of-band says nothing about the chart's smoke-test scaffolding. Use `tests.enabled=false` to drop them:
+
+```bash
+helm template aiperf-operator deploy/helm/aiperf-operator -n aiperf-system \
+  --set rbac.create=false \
+  --set serviceAccount.create=false \
+  --set serviceAccount.name=aiperf-operator-sa \
+  --set tests.enabled=false \
+  | grep -c '^kind: Cluster'   # -> 0
+```
+
+`tests.enabled` gates the hook Pods and their RBAC together, so you never get Pods referencing a ServiceAccount that was not created. Keeping `helm test` and reaching zero cluster-scoped RBAC are mutually exclusive: `…-test-crd` runs `kubectl get crd`, and CustomResourceDefinitions are cluster-scoped. With the hooks off, verify the install out-of-band with `kubectl get crd aiperfjobs.aiperf.nvidia.com aiperfsweeps.aiperf.nvidia.com` and `aiperf kube preflight`.
+
+## Troubleshooting
+
+| Symptom | Cause | Fix |
+|---|---|---|
+| `helm test` times out / fails on fresh install | `tests.image` not pullable (airgapped / proxied cluster) | Preload with `kind load docker-image alpine/k8s:1.33.11 --name <cluster>` or `docker save` → node import; or override `tests.image.repository` / `tests.image.tag` to a reachable image with `kubectl` + `curl`. |
+| `invalid ownership metadata` on reinstall | Previous uninstall kept the CRDs with the old release's metadata | See [Uninstall + reinstall behavior](#uninstall--reinstall-behavior). |
+| Operator pod stuck `ImagePullBackOff` | `image.repository` / `image.tag` not reachable from the cluster | Check `imagePullSecrets`; preload with `kind load docker-image` on kind clusters. |
+| Benchmark-pod image (CRD `spec.image` default) and operator image differ | `defaults.image` set explicitly to a different image | Either unset `defaults.image` (empty → computed from `image.*`) or set both to match. |
+| `helm test --logs` returns `unable to get pod logs` | Previous chart versions annotated test RBAC as `helm.sh/hook: test`, causing Helm to try fetching logs for non-Pod resources | Fixed in current chart — test RBAC is a regular resource. No action on a fresh install. |
+| `helm test` prints `TEST SUITE: None` and exits 0 | Release was installed or upgraded with `tests.enabled=false`, so no `helm.sh/hook: test` Pod is in the deployed revision | Expected. `helm upgrade --set tests.enabled=true` if you want the hooks, or run the equivalent checks out-of-band (see [`helm test` and cluster-scoped RBAC](#helm-test-and-cluster-scoped-rbac)). |

+AIPerf Operator has been installed!
+
+1. Verify the operator is running:
+   kubectl get pods -n {{ .Release.Namespace }} -l app.kubernetes.io/name={{ include "aiperf-operator.name" . }}
+
+2. Create a benchmark job:
+   cat <<EOF | kubectl apply -f -
+   apiVersion: aiperf.nvidia.com/v1alpha1
+   kind: AIPerfJob
+   metadata:
+     name: my-benchmark

+   spec:
+     # Deployment fields use camelCase (K8s convention)
+     image: {{ include "aiperf-operator.defaultJobImage" . }}

+     # Benchmark config lives under spec.benchmark in snake_case
+     # (identical to AIPerf CLI YAML config files)

+           type: concurrency
+           concurrency: 1
+           requests: 10
+   EOF
+
+3. Monitor progress:
+   aiperf kube list my-benchmark --watch
+
+   Or with kubectl:
+   kubectl get aiperfjob my-benchmark -n {{ .Release.Namespace }} -w
+
+4. View detailed status:
+   kubectl describe aiperfjob my-benchmark -n {{ .Release.Namespace }}
+
+5. Retrieve results:
+   aiperf kube results my-benchmark
+
+   The operator's HTTP API (jobs, sweeps, results, dashboard, metrics) is
+   reachable in-cluster at:
+       http://{{ include "aiperf-operator.fullname" . }}.{{ .Release.Namespace }}:{{ .Values.resultsServer.port }}
+   Out-of-cluster, port-forward and curl /api/v1/jobs:
+       kubectl -n {{ .Release.Namespace }} port-forward svc/{{ include "aiperf-operator.fullname" . }} 8081:{{ .Values.resultsServer.port }}
+       curl http://localhost:8081/api/v1/jobs
+
+{{- if .Values.storage.enabled }}
+
+   Results are also stored on the operator PVC at: {{ .Values.storage.mountPath }}/<job-id>/
+{{- end }}
+
+6. Run preflight checks against the cluster:
+   aiperf kube preflight --image {{ include "aiperf-operator.defaultJobImage" . }}

+              also accepts the snake_case names used in AIPerf CLI YAML,
+              but the apiserver schema only advertises camelCase.
+
+              Top-level deployment fields (image, podTemplate, scheduling,
+              etc.) use camelCase per Kubernetes API conventions.

+                  time but are not advertised by this schema, so kubectl/IDE tooling
+                  should write camelCase. Shorthand forms (e.g. models: ['name'],
+                  single-phase dict, top-level warmup/profiling) are accepted at marked

+         From prefill to production.
+ Kind · Minikube · Docker · GPU · Mock · vLLM · SGLang · TensorRT-LLM · Dynamo
+```
+
+Python CLI (`kube.py`) for building and running AIPerf in a local **Kind** or **minikube** cluster. Handles cluster lifecycle, image building, and server deployment. Benchmarks are deployed via AIPerf's Kubernetes runner and managed with `aiperf kube` commands. Run directly from the project root.
+
+The cluster runtime is chosen automatically: **minikube** when `nvidia-smi` is on `PATH` (simpler GPU passthrough), **Kind** otherwise. Force one with `CLUSTER_RUNTIME=kind` or `CLUSTER_RUNTIME=minikube`.
+
+---
+
+## Quick start (copy-paste)
+
+From the **project root**:
+
+```bash
+# 1. Install anything missing (docker, kind/minikube, kubectl, helm, k9s)
+./dev/kube.py doctor
+
+# 2. Full setup: cluster + images + Dynamo operator (GPU only) + AIPerf operator + JobSet + mock server
+./dev/kube.py setup
+
+# 3. Run a benchmark (attached)
+./dev/kube.py run
+```
+
+Or in one line after doctor:
+
+```bash
+./dev/kube.py setup && ./dev/kube.py run
+```
+
+**Teardown when done:**
+
+```bash
+./dev/kube.py teardown
+```
+
+---
+
+## Prerequisites
+
+| Tool      | Purpose                          |
+|-----------|----------------------------------|
+| **Docker** | Container runtime (Docker Desktop on Mac) |
+| **kind** *or* **minikube** | Local Kubernetes cluster — whichever the effective runtime selects |
+| **kubectl** | Kubernetes CLI                  |
+| **helm**  | Install Dynamo / AIPerf operators  |
+| **uv**    | Run AIPerf CLI (`run` generates manifests and attaches via `aiperf kube`) |
+
+Doctor's required set is `docker`, `kubectl`, `helm`, plus `kind` or `minikube` depending on the effective runtime. `uv` is not part of that check — `run` verifies it separately before attaching.
+
+**Optional:** **k9s** — terminal UI for the cluster (doctor can install it).
+
+Run **`./dev/kube.py doctor`** to check what's installed and interactively install missing tools (with platform-specific recipes for macOS, Arch, Debian/Ubuntu, Fedora, and generic Linux).

+| `./dev/kube.py run-local-detach`    | Deploy single-pod benchmark in background. |

+
+All AIPerf services run as subprocesses in one container (MULTIPROCESSING mode, ZMQ IPC). No JobSet CRD required.
+
+These variants take **no** `--config` / `--workers-max` options. They run `aiperf profile` directly, so every AIPerf argument is passed after `--`, and `--url` is injected automatically pointing at the in-cluster mock server:
+
+```bash
+./dev/kube.py run-local -- --model mock --endpoint-type chat --concurrency 4
+```
+
+Omitting the `--` arguments is an error.

+| `INSTALL_PREFIX`  | Linux install path for doctor-installed binaries (default `/usr/local`). |
+
+---
+
+## Workflows
+
+### First-time setup (CPU + mock)
+
+```bash
+./dev/kube.py doctor   # install docker, kind/minikube, kubectl, helm, (optional k9s)
+./dev/kube.py setup    # cluster + images + operators + JobSet + mock server
+./dev/kube.py run      # run benchmark against mock server
+```
+
+### Single-pod benchmark (simplest, no JobSet)
+
+```bash
+./dev/kube.py doctor
+./dev/kube.py setup
+./dev/kube.py run-local -- --model mock --endpoint-type chat                  # all services in one pod
+./dev/kube.py run-local -- --model mock --endpoint-type chat --concurrency 4  # smaller load
+```
+
+`run-local` runs all AIPerf services as subprocesses in a single Kubernetes Job. No JobSet CRD required, faster startup, lower resource overhead. Good for quick iteration on a local cluster.
+
+### GPU (vLLM)
+
+```bash
+./dev/kube.py doctor                           # ensure nvidia-smi + nvidia-ctk present
+./dev/kube.py setup                            # same as above
+./dev/kube.py deploy-vllm                      # deploy vLLM (default model, 1 GPU)
+./dev/kube.py run -c my-gpu.yaml               # benchmark against vLLM
+./dev/kube.py vllm-logs --follow
+./dev/kube.py remove-vllm
+```
+
+Custom model:
+
+```bash
+./dev/kube.py deploy-vllm --model facebook/opt-125m --gpus 1
+```
+
+### Dynamo (aggregated / disaggregated)
+
+```bash
+./dev/kube.py setup
+./dev/kube.py deploy-dynamo                            # aggregated (default)
+./dev/kube.py deploy-dynamo --mode disagg              # disaggregated
+./dev/kube.py deploy-dynamo --mode disagg-1gpu         # single-GPU disaggregated
+./dev/kube.py run -c dev/deploy/dynamo-benchmark-config.yaml
+./dev/kube.py dynamo-logs --follow
+./dev/kube.py remove-dynamo
+```
+
+### LoRA on Dynamo
+
+```bash
+./dev/kube.py deploy-dynamo
+./dev/kube.py deploy-lora --name my-lora --base-model Qwen/Qwen3-0.6B --source hf://org/repo
+# run benchmark using LoRA endpoint
+./dev/kube.py remove-lora --name my-lora
+```
+
+### Development iteration
+
+```bash
+# After code changes — rebuild, reload, and run:
+./dev/kube.py reload && ./dev/kube.py run
+
+# Single-pod (fastest iteration, no JobSet):
+./dev/kube.py reload && ./dev/kube.py run-local -- --model mock --endpoint-type chat
+
+# Or run detached and monitor:
+./dev/kube.py reload && ./dev/kube.py run-detach
+uv run aiperf kube list <job_id> --watch
+uv run aiperf kube logs <job_id>
+```
+
+### Manage benchmarks (`aiperf kube`)
+
+The `run` / `run-detach` commands use AIPerf's Kubernetes runner to generate and deploy JobSet manifests. After deployment, benchmark lifecycle is managed via `aiperf kube`:
+
+```bash
+uv run aiperf kube list                # list all benchmark jobs
+uv run aiperf kube list <job_id> --watch  # watch status
+uv run aiperf kube attach <job_id>     # attach to running benchmark
+uv run aiperf kube logs <job_id>       # view logs
+uv run aiperf kube results <job_id>    # view results
+uv run aiperf kube cancel <job_id>     # cancel running benchmark
+uv run aiperf kube delete <job_id>     # delete benchmark resources
+```
+
+### Cleanup
+
+```bash
+./dev/kube.py cleanup   # remove benchmark namespaces only
+./dev/kube.py teardown  # delete entire local cluster
+```
+
+---
+

+
+The cluster is named `CLUSTER_NAME` (default `aiperf`) — a Kind cluster name or a minikube profile, depending on the runtime. The AIPerf image is built from the **project root** `Dockerfile` (`--target runtime`) and loaded into the cluster's image store.
+
+---
+
+## Troubleshooting
+
+| Issue | What to do |
+|-------|------------|
+| Tools missing | `./dev/kube.py doctor` and accept installs. |
+| Wrong cluster runtime picked | Set `CLUSTER_RUNTIME=kind` or `CLUSTER_RUNTIME=minikube`. |
+| Docker not running | Start Docker Desktop (Mac: `open -a Docker`; Linux: `sudo systemctl start docker` or see doctor hint). |
+| Cluster won't start | `./dev/kube.py cluster-delete` then `./dev/kube.py setup` (or `./dev/kube.py cluster-create`). |
+| Images not in cluster | `./dev/kube.py build && ./dev/kube.py load`. |
+| Benchmark stuck | `uv run aiperf kube list <job_id> --watch`, `uv run aiperf kube logs <job_id>`, then `uv run aiperf kube cancel <job_id>` or `./dev/kube.py cleanup` and retry. |
+| Need full reset | `./dev/kube.py teardown` then `./dev/kube.py setup`. |
+
+**macOS:** Cluster is CPU-only; use `deploy-mock` for local dev. For vLLM/Dynamo you need a Linux cluster with NVIDIA GPUs.
+
+---
+
+## Quick reference

+# Quick start: install deps → cluster + mock → benchmark

+# Operator UI visual verification
+
+Renders the operator web UI, screenshots every page, and asserts the
+presentation contracts that past regressions violated. Two modes, and the
+difference between them matters.
+
+Run the Node and `capture_fixtures.py` commands from this directory
+(`dev/ui-verify`); the results-server command below is repo-root relative.
+
+    npm install playwright && npx playwright install chromium
+
+## Mode 1 (preferred): drive the real results-server
+
+The results-server registers the `/api/v1/*` routers and then mounts the UI as
+static files at `/` (`create_app` in `src/aiperf/operator/results_server.py`), so
+one process serves the whole stack from source — no cluster, image build, or
+deploy:
+
+    .venv/bin/python -c "import uvicorn; from pathlib import Path; \
+      from aiperf.operator.results_server import create_app; \
+      uvicorn.run(create_app(results_dir=Path('artifacts/ui-verify/pvc')), \
+                  host='127.0.0.1', port=8098)"
+
+    NAMESPACE=<namespace> node shoot.mjs
+                            # BASE defaults to http://127.0.0.1:8098
+
+Get a PVC tree by tarring the sweep dirs out of the operator pod:
+
+    kubectl -n <ns> exec deploy/aiperf-operator -c results-server -- sh -c \
+      'cd ${AIPERF_RESULTS_DIR:-/data} && tar czf - <ns>/sweeps/<sweep> <ns>/<sweep>-v*' \
+      > pvc.tgz
+
+**Use this mode.** It is the only one that can catch a wrong request.
+
+## Mode 2 (offline): replay captured fixtures
+
+    mkdir -p fixtures    # serve.mjs reads fixtures/api.json; the dir is not in git
+    python3 capture_fixtures.py --base http://127.0.0.1:8098 \
+        --namespace <ns> --sweep <sweep> > fixtures/api.json
+    node serve.mjs                                  # PORT, default 8099
+    BASE=http://127.0.0.1:8099 NAMESPACE=<namespace> node shoot.mjs
+
+Repeat `--sweep` once per sweep. `shoot.mjs` visits a fixed set of sweeps
+(`gemma-bo4`, `gemma-bo5`, `gemma-conc2`, `cp-sweep`) inside `NAMESPACE`, so
+capture those names to exercise every page.
+
+`serve.mjs` answers unmatched paths with an empty-but-valid body so the SPA
+does not render an error card. That convenience is also this mode's blind spot:
+**a page requesting the WRONG URL looks identical to one requesting the right
+URL.** A real bug — every sweep fetching the *previous* sweep's epoch and
+404ing, so the artifacts card claimed "No aggregate artifacts available" for
+sweeps that had them — survived a full review cycle behind exactly that.
+
+Fixtures also starve any page whose endpoints you did not capture: the
+leaderboard renders 927 chars of empty state under replay versus 5624 against
+the real server. That is why every page now carries a "did it render" check.
+
+## Lessons encoded here
+
+Each of these cost a real defect:
+
+- **Assert positive content, not absence.** A full set of green assertions once
+  passed against a winner card reading "No completed variation has a finite
+  Output tok/s value yet". Every check was "the bad string is absent", which an
+  empty page satisfies trivially.
+- **Query the element, not body text.** Body text cannot distinguish "the
+  planner cell id appears somewhere" (intended — it is kept as a subtitle
+  because it is the artifact path) from "the cell id IS the headline" (the
+  defect). Use `data-testid`.
+- **Every page gets at least one render check.** Without them the run printed
+  ALL CHECKS PASSED while two pages showed only their empty states, so the
+  commits touching those pages had no verification at all.
+- **Do not trust `fullPage: true`.** The app renders inside an inner scroll
+  container, so `document.scrollHeight === window.innerHeight` and Playwright
+  images only the first screen. Two pages with visibly different tables
+  produced byte-identical PNGs. This harness uses a tall viewport instead.
+- **Capture the per-child calls.** `/api/v1/jobs/{ns}/{child}` populates
+  metrics and the per-epoch artifact listings populate the artifacts card.
+  Omit them and the page renders structurally fine and completely empty.
+
+## Notes
+
+`compare` deliberately has no content check: it renders only a job selector
+until two jobs are chosen, so an "empty" compare page is correct.
+
+`NO_PROXY=127.0.0.1,localhost` is required where `HTTP_PROXY` is set, or
+localhost requests are routed through the proxy and fail.
+
+The UI loads its vendored Preact, HTM, Signals, and Chart.js runtime from the
+same origin. The fixture server must therefore serve `.mjs` files as
+`text/javascript`; `serve.mjs` includes that mapping.
+
+Screenshots and `report.json` default to the gitignored repo-root
+`artifacts/ui-verify/shots`. Set `SHOT_DIR` to use another output directory; a
+relative value resolves against `dev/ui-verify`, not the repo root.

+Prefer pointing the harness at a live results-server (``BASE=...`` on

 The Records Manager does not hard-wire one handler per producer. Instead, every typed record carries a `record_type` class attribute and is fanned out through a metadata-driven routing table: each accumulator and stream exporter declares the record types it consumes via `record_types` in `plugins.yaml`, and `_dispatch_record` routes each record by `getattr(record, "record_type")` to all registered handlers. This makes each record type a dedicated channel.
 
-Accuracy benchmarking is one such dedicated channel, joining `metric_records`, `gpu_telemetry`, and `server_metrics`:
+Accuracy benchmarking and GPU telemetry use dedicated Records Manager channels.
+Server metrics use the same plugin metadata to select local consumers, but raw
+Prometheus snapshots remain inside Server Metrics Manager:
 
 | Channel (`record_type`) | Producer | Message | Consumers (`record_types`) |
 |---|---|---|---|
 | `metric_records` | Record Processor (`MetricRecordProcessor`) | `RecordsMessage` | `MetricsAccumulator`, JSONL/OTel stream exporters |
 | `accuracy` | Record Processor (`AccuracyRecordProcessor`) | `RecordsMessage` | `AccuracyAccumulator`, `AccuracyJSONLWriter` |
 | `gpu_telemetry` | GPU Telemetry Manager | `TelemetryRecordsMessage` | `GPUTelemetryAccumulator`, GPU JSONL writer |
-| `server_metrics` | Server Metrics Manager | `ServerMetricsRecordMessage` | `ServerMetricsAccumulator`, server-metrics JSONL writer |
+| `server_metrics` | Server Metrics Manager | None (manager-local callback) | `ServerMetricsAccumulator`, server-metrics JSONL writer, both hosted by Server Metrics Manager |
 
 **Two-stage record processing.** The `RecordProcessorService` runs two roles per parsed response (mirroring the accumulator/stream-exporter split on the consumer side): **producers** (`record_processor` category) parse and emit one finished typed record on a declared `record_type` channel — `MetricRecordProcessor` → `MetricRecordsData` (`metric_records`), `AccuracyRecordProcessor` → `AccuracyRecordsData` (`accuracy`) — and **observers** (`record_observer` category, e.g. the raw-record and outputs-json writers) receive a `RecordObserverContext` (the parsed record + all producer outputs keyed by `record_type`) and act without emitting a channel record. Each producer's output carries its own serialized `record_type` discriminator, so the service ships **one generic `RecordsMessage`** per request — `{metadata, records: list[RecordData], error}` — and the `RecordsManager` dispatches each record to its channel handlers by `record.record_type` (no per-type message classes, no type-sniffing). The metric record is the canonical per-request record that drives the phase-completion lockstep, keyed off the message metadata.

 ### Communication Patterns
 
-AIPerf uses **ZMQ proxies** for message routing between services and workers:
+AIPerf runs two distinct planes over ZMQ: a **pub/sub event bus** for data and
+telemetry, and a **DEALER/ROUTER control channel** for orchestration.
+
+**Event bus (ZMQ proxies).** Services publish strongly-typed messages to topics
+and subscribe to the message types they care about. This carries every message
+type *except* commands: records, telemetry, progress, results, status
+broadcasts. Alongside it are the dedicated streaming channels:
 
-- Services publish strongly-typed messages to specific topics (Pub/Sub pattern)
-- Services subscribe to relevant message types
-- Router/Dealer pattern for credit dispatch to workers
+- ROUTER/DEALER for credit dispatch to workers
 - PUSH/PULL fan-in for credit returns from workers back to the Timing Manager
-- Request/Reply patterns for synchronous operations
+- Request/Reply for synchronous operations
 
 For low event-loop overhead, the streaming credit sockets (the dispatch DEALER/ROUTER and the return PUSH/PULL) are driven directly off the raw ZMQ file descriptor with an edge-triggered, non-blocking batch drain rather than per-message `await` wrappers.
 
+**Control channel.** Commands, service registration, heartbeats, and lifecycle
+status do **not** ride the event bus. Each component service opens a DEALER to
+`CommAddress.CONTROL` using its service ID as the ZMQ identity; the System
+Controller binds the single ROUTER. Payloads are `msgspec` tagged-union structs
+from `aiperf.common.control_structs` rather than Pydantic `Message` subclasses.
+
+```mermaid
+flowchart LR
+    subgraph controller["System Controller"]
+        ROUTER["ROUTER<br/>CommAddress.CONTROL<br/>ROUTER_MANDATORY"]
+    end

+    DM <--> ROUTER
+    WM <--> ROUTER
+    RM <--> ROUTER
+    OTHER <--> ROUTER
+```
+
+Because the ROUTER is the only path between two non-controller services, a
+command aimed at a peer is relayed by a controller-side handler rather than sent
+directly — this is how `PROFILE_COMPLETE` and `PROFILE_CANCEL` reach their
+sibling services.
+
+Addressing is symmetric in both directions:
+
+- **Controller to service**: identified by the DEALER identity. A one-shot
+  request awaits a response; a fan-out sends to an explicit list of service IDs.
+  There is no untargeted command broadcast.
+- **Service to controller**: `send_command_to_controller()` on the same socket.
+
+Each command carries a correlation id and is answered exactly once, with an ack,
+a result, an error, or an explicit "no handler" response. See
+[`docs/dev/patterns.md`](dev/patterns.md) § "Control Channel Command Pattern".
+
+Registration is deliberately the *second* readiness proof a service gives: it
+runs after the event-bus connection probe succeeds, so a registered service has
+demonstrated both planes are live.
+
+**Heartbeats are sent on both planes, on purpose.** Every service emits a
+`Heartbeat` struct on the control channel *and* a `HeartbeatMessage` on the event
+bus each interval. These are not duplicates and neither may be removed as one:
+
+| Send | Consumer | Consequence of losing it |
+|---|---|---|
+| `Heartbeat` (control channel) | System Controller's service registry | The service is declared unhealthy and reaped. |
+| `HeartbeatMessage` (event bus) | `TimingManager` feeds it to `StickyCreditRouter.note_worker_heartbeat` | `WorkerLoad.last_heartbeat_ns` has no other source once the registration-time value ages out. Every worker eventually looks stale to `evict_stale_workers`, failing any sufficiently long run with `Fatal worker loss: worker_unavailable`. |
+
+The bus heartbeat is intentionally not gated on registration — the credit
+router's liveness clock is independent of the controller's registration
+handshake — while the control-channel heartbeat is, so that services do not
+provoke "unknown service" warnings before they have registered.

-Run an AIPerf service in a single process.
+Exit immediately after deploying (don't wait for completion). Automatically enabled in non-interactive environments (pipes, CI/CD).
 
-_Advanced use only — intended for developers and Kubernetes/distributed deployments where services run in separate containers or nodes._
+#### `--no-wait`
 
-For standard single-node benchmarking, use the `aiperf profile` command instead.
+Don't wait for pods to be ready before attaching (advanced). In operator mode this returns as soon as the AIPerfJob is created.
 
-### Parameters
+#### `--attach-port` `<int>`
 
-#### `--type` `<str>` _(Required)_

+#### `--skip-endpoint-check`
 
-#### `--service-id` `<str>`
+Skip endpoint health validation before deploying.
+<br/>_Flag (no value required)_
 
-Unique identifier for the service instance. Useful when running multiple instances of the same service type.
+#### `--dry-run`
 
-#### `--health-host` `<str>`
+Print what would be submitted to stdout, then exit without contacting the cluster. Operator mode prints the AIPerfJob CR as JSON; --no-operator prints the Namespace, Role, RoleBinding, ConfigMap and JobSet as a multi-document YAML stream. Because no cluster is contacted, the mode shown is assumed, not detected: pass --no-operator to preview direct mode. The CR is also printed before AIPerfJobSpec validation, so a real submission may canonicalize snake_case keys to camelCase or reject keys a dry run prints.
+<br/>_Flag (no value required)_
 
-Host to bind the health server to. Falls back to AIPERF_SERVICE_HEALTH_HOST environment variable.
+#### `--operator`
 
-#### `--health-port` `<int>`
+Force operator deployment without probing the cluster-scoped AIPerfJob CRD. Use this with a pre-provisioned namespace when RBAC is namespace-scoped.
+<br/>_Flag (no value required)_
 
-HTTP port for health endpoints (/healthz, /readyz). Required for Kubernetes liveness and readiness probes. Falls back to AIPERF_SERVICE_HEALTH_PORT environment variable.
+#### `--no-operator`
+
+Force direct deployment without the operator. On a real (non-dry-run) deploy this is enabled automatically if the AIPerfJob CRD is not installed on the cluster; --dry-run never probes, so it always previews operator mode unless you pass this flag.

+When multiple models are specified, this is how a specific model should be assigned to a prompt. round_robin: nth prompt in the list gets assigned to n-mod len(models). random: assignment is uniformly random.
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `round_robin` | _default_ | Cycle through models in order. The nth prompt is assigned to model at index (n mod number_of_models). |
+| `random` |  | Randomly select a model for each prompt using uniform distribution. |
+| `weighted` |  | Select a model with probability proportional to a per-model weight. |
+
+#### `--custom-endpoint`, `--endpoint` `<str>`
+
+Set a custom API endpoint path (e.g., `/v1/custom`, `/my-api/chat`). By default, endpoints follow OpenAI-compatible paths like `/v1/chat/completions`. Use this option to override the default path for non-standard API implementations.
+
+#### `--endpoint-type` `<str>`
+
+The API endpoint type to benchmark. Determines request/response format and supported features. Common types: `chat` (multi-modal conversations), `embeddings` (vector generation), `completions` (text completion). See enum documentation for all supported endpoint types.
+<br/>_Choices: [`audio_transcription`, `chat`, `cohere_rankings`, `completions`, `responses`, `messages`, `chat_embeddings`, `embeddings`, `hf_tei_rankings`, `huggingface_generate`, `image_generation`, `image_edit`, `video_generation`, `image_retrieval`, `nim_embeddings`, `nim_rankings`, `solido_rag`, `raw`, `template`]_
+<br/>_Default: `chat`_
+
+#### `--streaming`
+
+Enable streaming responses. When enabled, the server streams tokens incrementally as they are generated. Automatically disabled if the selected endpoint type does not support streaming. Enables measurement of time-to-first-token (TTFT) and inter-token latency (ITL) metrics.
+<br/>_Flag (no value required)_
+
+#### `-u`, `--url` `<list>`
+
+Base URL(s) of the API server(s) to benchmark. Multiple URLs can be specified for load balancing across multiple instances (e.g., `--url http://server1:8000 --url http://server2:8000`). The endpoint path is automatically appended based on `--endpoint-type` (e.g., `/v1/chat/completions` for `chat`). URLs that do not include a scheme (no `://`) have `http://` prepended automatically.
+<br/>_Constraints: min: 1_
+<br/>_Default: `['http://localhost:8000']`_
+
+#### `--url-strategy` `<str>`
+
+Strategy for selecting URLs when multiple `--url` values are provided. 'round_robin' (default): distribute requests evenly across URLs in sequential order.
+<br/>_Choices: [`round_robin`]_
+<br/>_Default: `round_robin`_
+
+#### `--request-timeout-seconds` `<float>`
+
+Maximum time in seconds to wait for each HTTP request to complete, including connection establishment, request transmission, and response receipt. Applies to both streaming and non-streaming requests. Requests exceeding this timeout are cancelled and recorded as failures.
+<br/>_Constraints: > 0_
+<br/>_Default: `21600`_
+
+#### `--wait-for-model-timeout` `<float>`
+
+Seconds to wait for endpoint readiness before benchmarking (0 = skip). Sends a real inference request to verify the model is loaded and can generate output.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0.0`_
+
+#### `--wait-for-model-mode` `<str>`
+
+How readiness probes the endpoint: 'models' checks /v1/models, 'inference' sends a canned one-token inference request, and 'both' runs the models check before inference.
+<br/>_Default: `inference`_
+
+#### `--wait-for-model-interval` `<float>`
+
+Seconds between endpoint readiness probe attempts.
+<br/>_Constraints: > 0.0_
+<br/>_Default: `5.0`_
+
+#### `--reset-kv-cache`
+
+Enable once-per-cell KV-cache reset via POST to the endpoint.
+<br/>_Flag (no value required)_
+
+#### `--reset-kv-cache-timeout-seconds` `<float>`
+
+Timeout seconds for reset_kv_cache control requests.
+<br/>_Constraints: > 0_
+
+#### `--reset-kv-cache-path` `<str>`
+
+Relative path for reset_kv_cache (default /reset_prefix_cache).
+
+#### `--server-profiler`
+
+Enable server profiler start/stop around profiling phases.
+<br/>_Flag (no value required)_
+
+#### `--server-profiler-timeout-seconds` `<float>`
+
+Timeout seconds for server_profiler control requests.
+<br/>_Constraints: > 0_
+
+#### `--server-profiler-start-path` `<str>`
+
+Relative path for profiler start (default /start_profile).
+
+#### `--server-profiler-stop-path` `<str>`
+
+Relative path for profiler stop (default /stop_profile).
+
+#### `--api-key` `<str>`
+
+API authentication key for the endpoint. When provided, automatically included in request headers as `Authorization: Bearer <api_key>`.
+
+#### `--transport`, `--transport-type` `<str>`
+
+Transport protocol to use for API requests. If not specified, auto-detected from the URL scheme (`http`/`https` -> `TransportType.HTTP`). Currently supports `http` transport using aiohttp with connection pooling, TCP optimization, and Server-Sent Events (SSE) for streaming. Explicit override rarely needed.
+<br/>_Choices: [`http`]_
+
+#### `--use-legacy-max-tokens`
+
+Use the legacy 'max_tokens' field instead of 'max_completion_tokens' in request payloads. The OpenAI API now prefers 'max_completion_tokens', but some older APIs or implementations may require 'max_tokens'.
+<br/>_Flag (no value required)_
+
+#### `--use-server-token-count`
+
+Use server-reported token counts from API usage fields instead of client-side tokenization. When enabled, tokenizers are still loaded (needed for dataset generation) but tokenizer.encode() is not called for computing metrics. Token count fields will be None if the server does not provide usage information. For OpenAI-compatible streaming endpoints (chat/completions), stream_options.include_usage is automatically configured when this flag is enabled.
+<br/>_Flag (no value required)_
+
+#### `--per-chunk-usage`
+
+Request per-chunk token usage on streaming responses by setting stream_options.continuous_usage_stats, so the server reports cumulative usage on every chunk instead of only the final one. This lets inter-token latency subtract the first content chunk's real token count (fixing TPS/user inflation when a server bundles multiple tokens into the first streamed chunk). Requires a server that supports continuous_usage_stats (e.g. vLLM, TRT-LLM); strict OpenAI rejects it. Requires --use-server-token-count.
+<br/>_Flag (no value required)_
+
+#### `--connection-reuse-strategy` `<str>`
+
+Transport connection reuse strategy. 'pooled' (default): connections are pooled and reused across all requests. 'never': new connection for each request, closed after response. 'sticky-user-sessions': connection persists across turns of a multi-turn conversation, closed on final turn (enables sticky load balancing).
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `pooled` | _default_ | Connections are pooled and reused across all requests |
+| `never` |  | New connection for each request, closed after response |
+| `sticky-user-sessions` |  | Connection persists across turns of a multi-turn conversation, closed on final turn (enables sticky load balancing) |
+
+#### `--download-video-content`
+
+For video generation endpoints, download the video content after generation completes. When enabled, request latency includes the video download time. When disabled (default), only generation time is measured.
+<br/>_Flag (no value required)_
+
+#### `--request-content-type` `<str>`
+
+Content type for request body serialization. By default, requests are sent as 'application/json'. Set to 'multipart/form-data' for servers that require form-encoded requests (e.g., vLLM video generation endpoints).
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `application/json` |  | Standard JSON encoding. Default for all endpoints. |
+| `multipart/form-data` |  | Multipart form encoding. Required by some video generation servers (e.g., vLLM). |
+
+#### `--session-header` `<str>`
+
+HTTP header name used to carry the per-session affinity identifier. When set, replaces the default `X-Correlation-ID` header with the provided name (e.g., `--session-header X-Session-ID`).
+
+#### `--uuid-and-strip`
+
+Enable AIPerf-managed image stripping for vLLM's multimodal processor cache. Dataset-authored image UUIDs, including UUID-only cache references, always pass through on the chat endpoint; this flag only strips repeated content after AIPerf observes it in the same session. Automatic stripping supports only single_turn datasets with session_id-grouped rows; multi_turn is rejected. The server cache must cover the working set, and requests in a session must reach a replica that retains earlier UUIDs.
+<br/>_Flag (no value required)_
+
+### Tokenizer
+
+#### `--tokenizer` `<str>`
+
+HuggingFace tokenizer identifier, local path, or `builtin` for token counting in prompts and responses. Accepts model names (e.g., `meta-llama/Llama-2-7b-hf`), filesystem paths to tokenizer files, or `builtin` for a zero-network-access tokenizer backed by tiktoken (o200k_base encoding). If not specified, defaults to the value of `--model-names`. If `--tokenizer` is not set and the model name looks like an obvious placeholder (e.g. `mock-model`, `test-model`, `fake-model`), AIPerf substitutes `builtin` automatically and emits a warning. Essential for accurate token-based metrics (input/output token counts, token throughput).
+
+#### `--tokenizer-revision` `<str>`
+
+Specific tokenizer version to load from HuggingFace Hub. Can be a branch name (e.g., `main`), tag name (e.g., `v1.0`), or full commit hash. Ensures reproducible tokenization across runs by pinning to a specific version. Defaults to `main` branch if not specified.
+<br/>_Default: `main`_
+
+#### `--tokenizer-trust-remote-code`
+
+Allow execution of custom Python code from HuggingFace Hub tokenizer repositories. Required for tokenizers with custom implementations not in the standard `transformers` library. **Security Warning**: Only enable for trusted repositories, as this executes arbitrary code. Unnecessary for standard tokenizers.
+<br/>_Flag (no value required)_
+
+#### `--apply-chat-template`
+
+Apply the HuggingFace tokenizer's chat template when counting input tokens. When enabled: synthetic ISL is compensated for chat-template wrapping (BOS, role headers, EOT, generation-prompt suffix) and the record processor reports ISL using `apply_chat_template(tokenize=True, add_generation_prompt=True)` for chat-shape payloads. When disabled (default), both paths use bare-text encoding, so reported ISL matches the prompt content the user asked for and ignores template overhead. Requires an HF tokenizer with a chat template configured; no-ops on tiktoken / un-templated models.
+<br/>_Flag (no value required)_
+
+### Input
+
+#### `--extra-inputs` `<list>`
+
+Additional input parameters to include in every API request payload. Specify as `key:value` pairs (e.g., `--extra-inputs temperature:0.7 top_p:0.9`) or as JSON string (e.g., `'{"temperature": 0.7}'`). These parameters are merged with request-specific inputs and sent directly to the endpoint API.
+
+#### `-H`, `--header` `<list>`
+
+Custom HTTP headers to include with every request. Specify as `Header:Value` pairs (e.g., `--header X-Custom-Header:value`) or as JSON string. Can be specified multiple times. Useful for custom authentication, tracking, or API-specific requirements. Combined with auto-generated headers (e.g., `Authorization` from `--api-key`).
+
+#### `--input-file` `<str>`
+
+Path to file or directory containing benchmark dataset. Required when using `--custom-dataset-type`. Supported formats depend on dataset type: JSONL for `single_turn`/`multi_turn`, JSONL for `mooncake_trace`/`bailian_trace` (timestamped traces), Parquet for `baseten_trace`, directories for `random_pool`. File is parsed according to `--custom-dataset-type` specification.
+
+#### `--public-dataset` `<str>`
+
+Pre-configured public dataset to download and use for benchmarking (e.g., `sharegpt`). AIPerf automatically downloads and parses these datasets. Mutually exclusive with `--custom-dataset-type`. Run `aiperf plugins public_dataset_loader` to list available datasets. Use `--hf-subset` to override the HuggingFace subset/config for HF-backed datasets.
+<br/>_Choices: [`exgentic_v2`, `exgentic`, `sharegpt`, `aimo`, `mmstar`, `mmvu`, `vision_arena`, `llava_onevision`, `aimo_aime`, `aimo_numina_cot`, `aimo_numina_1_5`, `spec_bench`, `spec_al_gsm8k`, `spec_al_math500`, `spec_al_humaneval`, `spec_al_mbpp`, `spec_al_mtbench`, `instruct_coder`, `blazedit_5k`, `blazedit_10k`, `librispeech`, `voxpopuli`, `gigaspeech`, `ami`, `spgispeech`, `semianalysis_cc_traces_weka`, `semianalysis_cc_traces_weka_no_subagents`, `semianalysis_cc_traces_weka_with_subagents`, `semianalysis_cc_traces_weka_with_subagents_256k`, `semianalysis_cc_traces_weka_with_subagents_060226`, `semianalysis_cc_traces_weka_with_subagents_060226_256k`, `semianalysis_cc_traces_weka_with_subagents_060526`, `semianalysis_cc_traces_weka_with_subagents_060526_256k`, `semianalysis_cc_traces_weka_with_subagents_060826`, `semianalysis_cc_traces_weka_with_subagents_060826_256k`, `semianalysis_cc_traces_weka_061326`, `semianalysis_cc_traces_weka_061326_256k`, `semianalysis_cc_traces_weka_061526`, `semianalysis_cc_traces_weka_061526_256k`, `semianalysis_cc_traces_weka_062126`, `semianalysis_cc_traces_weka_062126_256k`, `weka_hf`]_
+
+#### `--hf-subset` `<str>`
+
+HuggingFace dataset subset/config name to override the plugin default (e.g. `sharegpt4o`). Only applies when using `--public-dataset` with a HuggingFace-backed loader. Takes priority over the subset defined in the plugin registry.
+
+#### `--hf-weka-dataset` `<str>`
+
+HuggingFace dataset repo for the generic Weka loader (e.g. `semianalysisai/cc-traces-weka-061526`). Passing this auto-selects `--public-dataset weka_hf`, so the repo flag works on its own; setting it alongside any other `--public-dataset` or `--custom-dataset-type` is an error. Pinned Weka public dataset aliases keep their registry-defined repo names.
+
+#### `--dataset-filter` `<list>`
+
+Dataset-specific filter in key=value form. Repeat for multiple filters. Only supported by public datasets that declare filter support.
+
+#### `--custom-dataset-type` `<str>`
+
+Format specification for custom dataset provided via `--input-file`. Determines parsing logic and expected file structure. Options: `single_turn` (JSONL with single exchanges), `multi_turn` (JSONL with conversation history), `tracelab` (TraceLab agentic-coding corpus, JSONL or gzipped JSONL), `mooncake_trace`/`bailian_trace`/`baseten_trace` (timestamped trace files), `random_pool` (directory of reusable prompts; when using `random_pool`, `--conversation-num` defaults to 100 if not specified; batch sizes > 1 sample each modality independently from a flat pool and do not preserve per-entry associations - use `single_turn` if paired modalities must stay together). Requires `--input-file`. Mutually exclusive with `--public-dataset`.
+<br/>_Choices: [`burst_gpt_trace`, `bailian_trace`, `baseten_trace`, `mooncake_trace`, `raw_payload`, `inputs_json`, `dag_jsonl`, `sagemaker_data_capture`, `multi_turn`, `random_pool`, `single_turn`, `speed_bench_qualitative`, `speed_bench_coding`, `speed_bench_humanities`, `speed_bench_math`, `speed_bench_multilingual`, `speed_bench_qa`, `speed_bench_rag`, `speed_bench_reasoning`, `speed_bench_roleplay`, `speed_bench_stem`, `speed_bench_summarization`, `speed_bench_writing`, `speed_bench_throughput_1k`, `speed_bench_throughput_2k`, `speed_bench_throughput_8k`, `speed_bench_throughput_16k`, `speed_bench_throughput_32k`, `speed_bench_throughput_1k_low_entropy`, `speed_bench_throughput_1k_mixed`, `speed_bench_throughput_1k_high_entropy`, `speed_bench_throughput_2k_low_entropy`, `speed_bench_throughput_2k_mixed`, `speed_bench_throughput_2k_high_entropy`, `speed_bench_throughput_8k_low_entropy`, `speed_bench_throughput_8k_mixed`, `speed_bench_throughput_8k_high_entropy`, `speed_bench_throughput_16k_low_entropy`, `speed_bench_throughput_16k_mixed`, `speed_bench_throughput_16k_high_entropy`, `speed_bench_throughput_32k_low_entropy`, `speed_bench_throughput_32k_mixed`, `speed_bench_throughput_32k_high_entropy`, `tracelab`, `weka_trace`]_
+
+#### `--ignore-trace-delays`
+
+Strip per-turn timestamps and inter-turn delays from trace datasets at load time. With this flag, Turn.timestamp and Turn.delay are emitted as None so concurrency / request-rate timing modes dispatch turns back-to-back instead of reproducing the recorded user think-time gaps. No effect under `--fixed-schedule` (timestamps drive that mode before they could be ignored -- combine with `--no-fixed-schedule` if you want both behaviors).
+<br/>_Flag (no value required)_
+
+#### `--use-think-time-only`
+
+For weka_trace inputs, emit Turn.delay using only the recorded per-request `think_time` (client-side delay before each request) instead of the full `t_curr - t_prev` inter-request delta. Compresses replay wall time against zero-latency mocks because the recorded `api_time` portion of each gap is dropped. Mirrors kv-cache-tester's default `--timing-strategy think-only`. Falls back to the full delta for turns whose recorded `think_time` is null. Mutually exclusive with `--ignore-trace-delays`. No effect on non-weka trace loaders.
+<br/>_Flag (no value required)_
+
+#### `--max-context-length` `<int>`
+
+Maximum peak prompt+output context length (tokens) per Weka root trace. Weka loaders (--custom-dataset-type weka_trace or a weka --public-dataset) drop whole traces whose *recorded* peak exceeds this ceiling at load time (filter-then-cap before --num-dataset-entries). Not a DatasetManager tokenize filter; rejected for non-Weka formats.
+<br/>_Constraints: ≥ 1_
+
+#### `--dataset-sampling-strategy` `<str>`
+
+Strategy for selecting entries from dataset during benchmarking. `sequential`: Iterate through dataset in order, wrapping to start after end. `random`: Randomly sample with replacement (entries may repeat before all are used). `shuffle`: Shuffle dataset and iterate without replacement, re-shuffling after exhaustion. Default behavior depends on dataset type (e.g., `sequential` for traces, `shuffle` for synthetic).
+<br/>_Choices: [`random`, `sequential`, `shuffle`]_
+
+#### `--allow-dataset-wrap`, `--no-allow-dataset-wrap`
+
+Allow weka/agentic replay to wrap (reuse distinct eligible traces across concurrency lanes) when concurrency exceeds the loaded pool. Defaults to False: over-subscription fails unless wrapping is explicitly enabled or an active --cache-bust target already keeps repeated-trace traffic distinct.
+
+#### `--random-seed` `<int>`
+
+Random seed for deterministic data generation. When set, makes synthetic prompts, sampling, delays, and other random operations reproducible across runs. Essential for A/B testing and debugging. Uses system entropy if not specified. Initialized globally at config creation.
+<br/>_Constraints: ≥ 0_
+
+#### `--trace-session-sample-ratio` `<float>`
+
+Fraction of trace sessions to keep for replay, sampled whole-session to preserve multi-turn integrity; deterministic when `--random-seed` is set. Only supported by the baseten_trace loader.
+<br/>_Constraints: > 0.0, ≤ 1.0_
+
+#### `-f`, `--config` `<str>`
+
+Path to a YAML configuration file. CLI flags override values from the config file. A flag that cannot be applied on top of a config file is rejected by name rather than ignored, so a run never silently differs from what was asked for.
+
+### Fixed Schedule
+
+#### `--fixed-schedule`
+
+Run requests according to timestamps specified in the input dataset. When enabled, AIPerf replays the exact timing pattern from the dataset. This mode is automatically enabled for trace datasets.
+<br/>_Flag (no value required)_
+
+#### `--no-fixed-schedule`
+
+Suppress the automatic switch to fixed-schedule mode for trace datasets that carry per-record timestamps. By default a trace input (e.g. mooncake_trace) with timestamps in the first record auto-promotes the profiling phase to fixed_schedule. Pass --no-fixed-schedule to keep the user-selected timing mode (e.g. concurrency, request_rate) and ignore the trace timestamps.
+
+#### `--fixed-schedule-auto-offset`
+
+Automatically normalize timestamps in fixed schedule by shifting all timestamps so the first timestamp becomes 0. When enabled, benchmark starts immediately with the timing pattern preserved. When disabled, timestamps are used as absolute offsets from benchmark start. Mutually exclusive with `--fixed-schedule-start-offset`.
+<br/>_Flag (no value required)_
+
+#### `--fixed-schedule-start-offset` `<int>`
+
+Start offset in milliseconds for fixed schedule replay. Skips all requests before this timestamp, allowing benchmark to start from a specific point in the trace. Requests at exactly the start offset are included. Useful for analyzing specific time windows. Mutually exclusive with `--fixed-schedule-auto-offset`. Must be ≤ `--fixed-schedule-end-offset` if both specified.
+<br/>_Constraints: ≥ 0_
+
+#### `--fixed-schedule-end-offset` `<int>`
+
+End offset in milliseconds for fixed schedule replay. Stops issuing requests after this timestamp, allowing benchmark of specific trace subsets. Requests at exactly the end offset are included. Defaults to last timestamp in dataset. Must be ≥ `--fixed-schedule-start-offset` if both specified.
+<br/>_Constraints: ≥ 0_
+
+### Goodput
+
+#### `--goodput` `<str>`
+
+Specify service level objectives (SLOs) for goodput as space-separated 'KEY:VALUE' pairs, where KEY is a metric tag and VALUE is a number in the metric's display unit (falls back to its base unit if no display unit is defined). Examples: 'request_latency:250' (ms), 'inter_token_latency:10' (ms), `output_token_throughput_per_user:600` (tokens/s). Only metrics applicable to the current endpoint/config are considered. For more context on the definition of goodput, refer to DistServe paper: https://arxiv.org/pdf/2401.09670 and the blog: https://hao-ai-lab.github.io/blogs/distserve.
+
+### Conversation Input
+
+#### `--conversation-num`, `--num-conversations`, `--num-sessions` `<str>`
+
+The total number of unique conversations to generate. Each conversation represents a single request session between client and server. Supported on synthetic mode and the custom random_pool dataset. The number of conversations will be used to determine the number of entries in both the custom random_pool and synthetic datasets and will be reused until benchmarking is complete. Pass a comma-separated list (e.g. `--num-conversations 50,100,200`) to sweep over session-bounded run lengths; the converter promotes the list to a sweep on phases.profiling.sessions before AIPerfConfig validation. The synthetic dataset pool is sized to max(list) so every variation has its full unique-session set.
+
+#### `--num-dataset-entries`, `--num-prompts` `<int>`
+
+Total number of unique entries to generate for the dataset. Each entry represents one user message that can be used as a turn in conversations. Entries are reused across conversations and turns according to `--dataset-sampling-strategy`. Higher values provide more diversity.
+<br/>_Constraints: ≥ 1_
+<br/>_Default: `100`_
+
+#### `--conversation-turn-mean`, `--session-turns-mean` `<int>`
+
+Mean number of request-response turns per conversation. Each turn consists of a user message and model response. Turn counts follow normal distribution around this mean (±`--conversation-turn-stddev`). Set to 1 for single-turn interactions. Multi-turn conversations enable testing of context retention and conversation history handling. Pass a comma-separated list (e.g. `--conversation-turn-mean 1,3,8`) to sweep over multiple turn-mean values; the converter promotes the list to a sweep on datasets.main.turns.mean before AIPerfConfig validation.
+<br/>_Default: `1`_
+
+#### `--conversation-turn-stddev`, `--session-turns-stddev` `<int>`
+
+Standard deviation for number of turns per conversation. Creates variability in conversation lengths, simulating diverse interaction patterns (quick questions vs. extended dialogues). Turn counts follow normal distribution. Set to 0 for uniform conversation lengths.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0`_
+
+#### `--conversation-turn-delay-mean`, `--session-turn-delay-mean` `<float>`
+
+Mean delay in milliseconds between consecutive turns within a multi-turn conversation. Simulates user think time between receiving a response and sending the next message. Delays follow normal distribution around this mean (±`--conversation-turn-delay-stddev`). Only applies to multi-turn conversations (`--conversation-turn-mean` > 1). Set to 0 for back-to-back turns.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0.0`_
+
+#### `--conversation-turn-delay-stddev`, `--session-turn-delay-stddev` `<float>`
+
+Standard deviation for turn delays in milliseconds. Creates variability in user think time between conversation turns. Delays follow normal distribution. Set to 0 for deterministic delays. Models realistic human interaction patterns with variable response times.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0.0`_
+
+#### `--conversation-turn-delay-ratio`, `--session-delay-ratio` `<float>`
+
+Multiplier for scaling all turn delays within conversations. Applied after mean/stddev calculation: `actual_delay = calculated_delay × ratio`. Use to proportionally adjust timing without changing distribution shape. Values &lt; 1 speed up conversations, > 1 slow them down. Set to 0 to eliminate delays entirely.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `1.0`_
+
+#### `--inter-turn-delay-cap-seconds` `<float>`
+
+Clamp per-turn replay delays to at most this many seconds; ``None`` disables the cap. Honored by the DAG JSONL loader and the baseten_trace loader's closed-loop think-times; the clamp count is reported at end of load. Maps to FileDataset ``inter_turn_delay_cap_seconds``.
+<br/>_Constraints: ≥ 0.0_
+
+#### `--max-idle-gap-cap-seconds` `<float>`
+
+Collapse idle gaps between consecutive requests (across all sessions) to at most this many seconds, so a sparse or session-sampled trace does not replay dead air; ``None`` disables the cap. The cap is in replay wall-clock seconds, applied after --replay-speedup compression, so it bounds actual benchmark idle time regardless of speedup. Only supported by the baseten_trace loader. Maps to FileDataset ``max_idle_gap_cap_seconds``.
+<br/>_Constraints: > 0.0_
+
+#### `--replay-speedup` `<float>`
+
+Trace replay wall-clock compression (10 = 10x faster than recorded): divides normalized timestamps and inter-turn delays; ``None`` = real time. Unlike synthesis speedup_ratio, hash_ids stay untouched (KV-cache fidelity). Only supported by the baseten_trace loader. Maps to FileDataset ``replay_speedup``.
+<br/>_Constraints: > 0.0_
+
+#### `--open-loop-replay`, `--no-open-loop-replay`
+
+Open-loop replay (the default): each session starts at its absolute, speedup-scaled recorded timestamp; continuation turns fire at max(recorded timestamp, prior-turn completion). Pass `--no-open-loop-replay` for closed-loop back-pressure: continuation turns fire a think-time (recorded start-to-start gap minus recorded e2e duration) after the prior turn completes, keeping sessions causally ordered when replayed service times differ from recorded (e.g. A/A comparisons). Only honored by the baseten_trace loader. Maps to FileDataset ``open_loop_replay``.
+<br/>_Default: `True`_
+
+#### `--open-loop-strict`
+
+In open-loop replay, fire every trace row at its absolute recorded timestamp as an independent single-turn session, trading away multi-turn grouping and session metrics. Only honored by the baseten_trace loader. Maps to FileDataset ``open_loop_strict``.
+<br/>_Flag (no value required)_
+
+#### `--omit-kv-hints`
+
+Drop recorded KV-cache hints (``hash_ids``, ``block_size``) from replayed request bodies, for strict frontends that reject unknown parameters. Only honored by the baseten_trace loader. Maps to FileDataset ``omit_kv_hints``.
+<br/>_Flag (no value required)_
+
+#### `--force-min-tokens`, `--no-force-min-tokens`
+
+Pin ``min_tokens`` to the recorded output length so replayed generations match recorded lengths; pass `--no-force-min-tokens` to let EOS end generations naturally (some servers reject ``min_tokens``). Only honored by the baseten_trace loader. Maps to FileDataset ``force_min_tokens``.
+<br/>_Default: `True`_
+
+### Prompt
+
+#### `-b`, `--prompt-batch-size`, `--batch-size-text`, `--batch-size` `<int>`
+
+Number of text inputs to include in each request for batch processing endpoints. Supported by `embeddings` and `rankings` endpoint types where models can process multiple inputs simultaneously for efficiency. Set to 1 for single-input requests. Not applicable to `chat` or `completions` endpoints.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `1`_
+
+#### `--prompt-corpus` `<str>`
+
+Source corpus for synthetic prompt text generation. 'sonnet' uses Shakespeare sonnets. 'coding' uses realistic coding content (code, bash output, JSON, error tracebacks, git diffs). Honored only for synthesized content (synthetic datasets and count/hash-id trace loaders); verbatim formats ignore it. When unset, the active dataset loader's default applies (most loaders default to 'sonnet'; agentic-coding loaders such as weka_trace default to 'coding').
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `sonnet` |  | Shakespeare sonnets (default). Classic prose for filler text. |
+| `coding` |  | Realistic coding content: code, bash output, JSON, error tracebacks, git diffs. |
+| `random` |  | Random tokens drawn from the full tokenizer vocabulary minus special tokens. Matches vLLM bench's RandomDataset token-generation strategy. |
+
+### Cache Bust
+
+#### `--cache-bust` `<str>`
+
+Where (and how) to inject a cache-bust marker. Two families: (1) RID targets (system_prefix, system_suffix, first_turn_prefix, first_turn_suffix) — inject a per-trajectory unique SHA-256 digest marker that is identical across warmup and profiling, so warmup KV-cache work transfers to profiling while preventing cross-trajectory cache sharing. Prefix variants prepend at token 0; suffix variants append after existing content. (2) Warmup-isolation targets (warmup_isolation_system, warmup_isolation_first_turn) — inject a constant '[warmup]' marker only during the WARMUP phase; profiling sees no marker (fully cold start or system-pre-warmed). Incompatible with agentic_replay timing mode. 'none' disables the feature (default). See [cache-bust.md](reference/cache-bust.md) for detailed semantics, trade-offs, and examples.
+<br/>_Choices: [`none`, `system_prefix`, `system_suffix`, `first_turn_prefix`, `first_turn_suffix`, `warmup_isolation_system`, `warmup_isolation_first_turn`]_
+<br/>_Default: `none`_
+
+### Prefix Prompt
+
+#### `--system-prompt` `<str>`
+
+Verbatim system prompt text, identical across every conversation. Sent as a system-role message ahead of all turns. Works with both synthetic and file/public datasets; when the dataset already carries its own system message, this text is prepended to it. Tokens are additive: `--isl` continues to size the generated user prompt only. Mutually exclusive with `--system-prompt-file`, `--shared-system-prompt-length`, and `--num-prefix-prompts`/`--prefix-prompt-length`.
+
+#### `--system-prompt-file` `<str>`
+
+Path to a UTF-8 text file holding the verbatim system prompt. Preferred over `--system-prompt` for real production prompts, which are long enough that shell quoting mangles them. Read once at startup, so a missing or unreadable file fails immediately rather than mid-run. Mutually exclusive with `--system-prompt`, `--shared-system-prompt-length`, and `--num-prefix-prompts`/`--prefix-prompt-length`.
+
+#### `--prompt-prefix-pool-size`, `--prefix-prompt-pool-size`, `--num-prefix-prompts` `<int>`
+
+Number of distinct prefix prompts to generate for K-V cache testing. Each prefix is prepended to user prompts, simulating cached context scenarios. Prefixes randomly selected from pool per request. Set to 0 to disable prefix prompts. Mutually exclusive with `--shared-system-prompt-length`/`--user-context-prompt-length`.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0`_
+
+#### `--prompt-prefix-length`, `--prefix-prompt-length` `<int>`
+
+The number of tokens in each prefix prompt. This is only used if `--num-prefix-prompts` is greater than zero. Note that due to the prefix and user prompts being concatenated, the number of tokens in the final prompt may be off by one.Mutually exclusive with `--shared-system-prompt-length`/`--user-context-prompt-length`.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0`_
+
+#### `--shared-system-prompt-length` `<int>`
+
+Length of shared system prompt in tokens. This prompt is identical across all sessions and appears as a system message. Mutually exclusive with `--prefix-prompt-length`/`--prefix-prompt-pool-size`.
+<br/>_Constraints: ≥ 1_
+
+#### `--user-context-prompt-length` `<int>`
+
+Length of per-session user context prompt in tokens. Each dataset entry gets a unique user context prompt. Requires --num-dataset-entries to be specified. Mutually exclusive with --prefix-prompt-length/--prefix-prompt-pool-size.
+<br/>_Constraints: ≥ 1_
+
+### Input Sequence Length (ISL)
+
+#### `--prompt-input-tokens-mean`, `--synthetic-input-tokens-mean`, `--isl` `<int>`
+
+Mean number of tokens for synthetically generated input prompts. AIPerf generates prompts with lengths following a normal distribution around this mean (±`--prompt-input-tokens-stddev`). Applies only to synthetic datasets, not custom or public datasets. Pass a comma-separated list (e.g. `--isl 128,512,2048`) to sweep over multiple input lengths; the converter promotes the list to a sweep on datasets.main.prompts.isl.mean before AIPerfConfig validation.
+<br/>_Default: `550`_
+
+#### `--prompt-input-tokens-stddev`, `--synthetic-input-tokens-stddev`, `--isl-stddev` `<float>`
+
+Standard deviation for synthetic input prompt token lengths. Creates variability in prompt sizes when > 0, simulating realistic workloads with mixed request sizes. Lengths follow normal distribution. Set to 0 for uniform prompt lengths. Applies only to synthetic data generation. Pass a comma-separated list (e.g. `--isl-stddev 10,50,200`) to sweep over multiple stddev values; the converter promotes the list to a sweep on datasets.main.prompts.isl.stddev. Pair with a zip-mode `--isl` sweep to model realistic small/medium/large traffic shapes.
+<br/>_Default: `0.0`_
+
+#### `--prompt-input-tokens-block-size`, `--synthetic-input-tokens-block-size`, `--isl-block-size` `<int>`
+
+Token block size for hash-based prompt synthesis when dataset entries carry `hash_ids`: each `hash_id` maps to a cached block of `block_size` tokens, enabling simulation of KV-cache sharing patterns from production workloads. The total prompt length equals `(num_hash_ids - 1) * block_size + final_block_size`. With `--input-file` this overrides the trace loader's `default_block_size` plugin metadata (16 for `bailian_trace`, 512 for `mooncake_trace`) for loaders that reconstruct prompts from `hash_ids`; it has no effect on `baseten_trace`, which replays literal recorded prompts. Set it when a trace was recorded at a block size different from its loader default (e.g. a Mooncake-format trace recorded at 16).
+<br/>_Constraints: ≥ 1_
+
+#### `--seq-dist`, `--sequence-distribution` `<str>`
+
+Distribution of (ISL, OSL) pairs with probabilities for mixed workload simulation. Format: `ISL,OSL:prob;ISL,OSL:prob` (semicolons separate pairs, probabilities are percentages 0-100 that must sum to 100). Supports optional stddev: `ISL|stddev,OSL|stddev:prob`. Examples: `128,64:25;512,128:50;1024,256:25` or with variance: `256|10,128|5:40;512|20,256|10:60`. Also supports bracket `[(256,128):40,(512,256):60]` and JSON formats.
+
+#### `--random-range-ratio` `<str>`
+
+Sample ISL and OSL uniformly from a ratio-defined integer window around the configured means. The window is computed from `--random-corpus-style` (defaults to `vllm`): vllm style → `[floor(mean*(1-r)), ceil(mean*(1+r))]` (symmetric); sglang style → `[max(1, int(mean*r)), mean]` (lower-bounded). Accepts a single float applied to both ISL and OSL. The JSON object form `{"input": 0.3, "output": 0.5}` for independent values is accepted only under vllm style; sglang style applies one ratio to both and requires a plain float. Requires both `--isl` and `--osl` to be set explicitly — there is no default mean for either. Mutually exclusive with `--seq-dist`. Under vllm style with a tokenizer configured, the ISL mean is automatically reduced by `tokenizer.num_special_tokens_to_add(pair=False)` so `--isl` represents total server-side input tokens, matching `vllm bench serve` semantics; sglang style applies no such adjustment.
+
+#### `--random-corpus-style` `<str>`
+
+Benchmark style for RANDOM corpus generation. Controls range ratio formula, token pool composition, and other per-tool behaviors. `vllm` (default) mirrors `vllm bench serve`: symmetric range window, non-special token pool (special tokens excluded). `sglang` mirrors `sglang.benchmark.serving` run with `--dataset-name random-ids`: lower-bounded range window, full `range(vocab_size)` token pool (no exclusion). Applies in two independent places: token-pool selection whenever `--prompt-corpus random` is set (including with no `--random-range-ratio`, where the pool is the only thing the style selects), and the range-window formula, special-token accounting and RNG algorithm whenever `--random-range-ratio` is set — the latter regardless of corpus.
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `vllm` | _default_ | vllm bench serve semantics: symmetric window ``[floor(mean*(1-r)), ceil(mean*(1+r))]``. r=0 is fixed at mean; larger r widens the window on both sides. r must be in [0, 1). Special tokens excluded from the sampling pool. BOS subtracted from ISL mean. |
+| `sglang` |  | sglang ``benchmark.serving`` semantics under ``--dataset-name random-ids``: lower-bounded window ``[max(1, int(mean*r)), mean]``. r=0 allows full variability [1, mean]; r=1 fixes length at mean. Full vocab_size range used for token sampling (no special-token exclusion). No BOS adjustment. The default ``--dataset-name random`` is a different algorithm upstream (repeat/truncate ShareGPT token ids) and is not what this style mirrors. |
+
+### Output Sequence Length (OSL)
+
+#### `--prompt-output-tokens-mean`, `--output-tokens-mean`, `--osl` `<str>`
+
+Mean number of tokens to request in model outputs via `max_completion_tokens` field. Controls response length for synthetic and some custom datasets. If specified, included in request payload to limit generation length. When not set, model determines output length. Pass a comma-separated list (e.g. `--osl 128,256,512`) to sweep over multiple output lengths; the converter promotes the list to a sweep on datasets.main.prompts.osl.mean before AIPerfConfig validation.
+
+#### `--prompt-output-tokens-stddev`, `--output-tokens-stddev`, `--osl-stddev` `<int>`
+
+Standard deviation for output token length requests. Creates variability in `max_completion_tokens` field across requests, simulating mixed response length requirements. Lengths follow normal distribution. Only applies when `--prompt-output-tokens-mean` is set. Pass a comma-separated list (e.g. `--osl-stddev 5,25,100`) to sweep over multiple stddev values; the converter promotes the list to a sweep on datasets.main.prompts.osl.stddev. Pair with a zip-mode `--osl` sweep to model realistic output-length variance across traffic tiers.
+<br/>_Default: `0`_
+
+### Audio Input
+
+#### `--audio-batch-size`, `--batch-size-audio` `<int>`
+
+The number of audio inputs to include in each request. Supported with the `chat` endpoint type for multimodal models.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `1`_
+
+#### `--audio-length-mean` `<float>`
+
+Mean duration in seconds for synthetically generated audio files. Audio lengths follow a normal distribution around this mean (±`--audio-length-stddev`). Used when `--audio-batch-size` > 0 for multimodal benchmarking. Generated audio is random noise with specified sample rate, bit depth, and format.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0.0`_
+
+#### `--audio-length-stddev` `<float>`
+
+Standard deviation for synthetic audio duration in seconds. Creates variability in audio lengths when > 0, simulating mixed-duration audio inputs. Durations follow normal distribution. Set to 0 for uniform audio lengths.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0.0`_
+
+#### `--audio-format` `<str>`
+
+File format for generated audio files. Supports `wav` (uncompressed PCM, larger files) and `mp3` (compressed, smaller files). Format choice affects file size in multimodal requests but not audio characteristics (sample rate, bit depth, duration).
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `wav` | _default_ | WAV format. Uncompressed audio, larger file sizes, best quality. |
+| `mp3` |  | MP3 format. Compressed audio, smaller file sizes, good quality. |
+
+#### `--audio-depths` `<list>`
+
+List of audio bit depths in bits to randomly select from when generating audio files. Each audio file is assigned a random depth from this list. Common values: `8` (low quality), `16` (CD quality), `24` (professional), `32` (high-end). Specify multiple values (e.g., `--audio-depths 16 24`) for mixed-quality testing.
+<br/>_Constraints: min: 1_
+<br/>_Default: `[16]`_
+
+#### `--audio-sample-rates` `<list>`
+
+A list of audio sample rates to randomly select from in kHz. Common sample rates are 16, 44.1, 48, 96, etc.
+<br/>_Constraints: min: 1_
+<br/>_Default: `[16.0]`_
+
+#### `--audio-num-channels` `<int>`
+
+Number of audio channels for synthetic audio generation. `1` = mono (single channel), `2` = stereo (left/right channels). Stereo doubles file size but simulates realistic audio for models supporting spatial audio processing. Most speech models use mono.
+<br/>_Constraints: ≥ 1, ≤ 2_
+<br/>_Default: `1`_
+
+### Image Input
+
+#### `--image-width-mean` `<float>`
+
+Mean width in pixels for synthetically generated images. Image widths follow a normal distribution around this mean (±`--image-width-stddev`). Combined with `--image-height-mean` to determine image dimensions and file sizes for multimodal benchmarking.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0.0`_
+
+#### `--image-width-stddev` `<float>`
+
+Standard deviation for synthetic image widths in pixels. Creates variability in horizontal resolution when > 0, simulating mixed-resolution image inputs. Widths follow normal distribution. Set to 0 for uniform image widths.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0.0`_
+
+#### `--image-height-mean` `<float>`
+
+Mean height in pixels for synthetically generated images. Image heights follow a normal distribution around this mean (±`--image-height-stddev`). Used when `--image-batch-size` > 0 for multimodal vision benchmarking. Generated images are resized from source images in `assets/source_images` directory.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0.0`_
+
+#### `--image-height-stddev` `<float>`
+
+Standard deviation for synthetic image heights in pixels. Creates variability in vertical resolution when > 0, simulating mixed-resolution image inputs. Heights follow normal distribution. Set to 0 for uniform image heights.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0.0`_
+
+#### `--image-batch-size`, `--batch-size-image` `<int>`
+
+Number of images to include in each multimodal request. Supported with `chat` endpoint type for vision-language models. Each image is generated by randomly sampling and resizing source images from `assets/source_images` directory to specified dimensions. Set to 0 to disable image inputs. Higher batch sizes test multi-image understanding and increase request payload size.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `1`_
+
+#### `--image-format` `<str>`
+
+Image file format for generated images. Choose `png` for lossless compression (larger files, best quality), `jpeg` for lossy compression (smaller files, good quality), or `random` to randomly select between PNG and JPEG for each image. Format affects file size in multimodal requests and encoding overhead.
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `png` | _default_ | PNG format. Lossless compression, larger file sizes, best quality. |
+| `jpeg` |  | JPEG format. Lossy compression, smaller file sizes, good for photos. |
+| `random` |  | Randomly select PNG or JPEG for each image. |
+
+#### `--image-source` `<str>`
+
+Source image generation mode (default `noise`). `noise` generates random noise images on the fly at the requested dimensions — no files on disk required, and the pool is effectively unbounded so servers cannot dedupe on identical inputs. `assets` indexes images from the built-in `assets/source_images` directory (ships with a small set of 4 images) and lazily loads them at the requested dimensions. A path to a directory indexes images from the given directory (e.g. `--image-source ./source_images`). Note: random-noise images are roughly incompressible, so payload bytes are larger than equivalent natural images.
+<br/>_Default: `noise`_
+
+#### `--image-source-sampling` `<str>`
+
+How source images are selected from finite image sources selected by `--image-source assets` or `--image-source <directory>`. `random-with-replacement` draws each source image independently; repeats may occur immediately. `shuffle-cycle` draws every source image once per shuffled cycle, reshuffling after exhaustion. `sequential-cycle` walks source images in sorted load order and wraps after exhaustion. For `noise`, only `random-with-replacement` is valid because there is no finite source pool.
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `random-with-replacement` | _default_ | Draw each source image independently; repeats may occur immediately. |
+| `shuffle-cycle` |  | Draw every source image once per shuffled cycle; reshuffle after exhaustion. |
+| `sequential-cycle` |  | Walk source images in sorted load order; wrap after exhaustion. |
+
+### Video Input
+
+#### `--video-batch-size`, `--batch-size-video` `<int>`
+
+Number of video files to include in each multimodal request. Supported with `chat` endpoint type for video understanding models. Each video is generated synthetically with specified duration, FPS, resolution, and codec. Set to 0 to disable video inputs. Higher batch sizes test multi-video understanding and significantly increase request payload size.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `1`_
+
+#### `--video-duration` `<float>`
+
+Duration in seconds for each synthetically generated video clip. Combined with `--video-fps`, determines total frame count (frames = duration × FPS). Longer durations increase file size and processing time. Typical values: 1-10 seconds for testing. Requires FFmpeg for video generation.
+<br/>_Constraints: ≥ 0.0_
+<br/>_Default: `5.0`_
+
+#### `--video-fps` `<int>`
+
+Frames per second for generated video. Higher FPS creates smoother video but increases frame count and file size. Common values: `4` (minimal motion, recommended for Cosmos models), `24` (cinematic), `30` (standard video), `60` (high frame rate). Total frames = `--video-duration` × FPS.
+<br/>_Constraints: ≥ 1_
+<br/>_Default: `4`_
+
+#### `--video-width` `<int>`
+
+Video frame width in pixels. Must be specified together with `--video-height` (both or neither). Determines video resolution and file size. Common resolutions: `640×480` (SD), `1280×720` (HD), `1920×1080` (Full HD). If not specified, uses codec/format defaults.
+<br/>_Constraints: ≥ 1_
+
+#### `--video-height` `<int>`
+
+Video frame height in pixels. Must be specified together with `--video-width` (both or neither). Combined with width determines aspect ratio and total pixel count per frame. Higher resolution increases processing demands and file size.
+<br/>_Constraints: ≥ 1_
+
+#### `--video-synth-type` `<str>`
+
+Algorithm for generating synthetic video content. Different types produce different visual patterns for testing. Options: `moving_shapes` (animated geometric shapes), `grid_clock` (grid with rotating clock hands), `noise` (random pixel frames). Content doesn't affect semantic meaning but may impact encoding efficiency and file size.
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `moving_shapes` | _default_ | Generate videos with animated geometric shapes moving across the frame |
+| `grid_clock` |  | Generate videos with a grid pattern and frame number overlay for frame-accurate verification |
+| `noise` |  | Generate videos with random noise frames |
+
+#### `--video-format` `<str>`
+
+Container format for generated video files. Supports `webm` (VP9, recommended, BSD-licensed) and `mp4` (widely compatible container, VP9 by default). Format choice affects compatibility, file size, and encoding options. `mp4` is the more portable container, but note that the default VP9 video and Opus audio are less widely supported by players than H.264/AAC would be.
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `mp4` |  | MP4 container. Widely compatible, good for H.264/H.265 codecs. |
+| `webm` | _default_ | WebM container. Open format, optimized for web, good for VP9 codec. |
+
+#### `--video-codec` `<str>`
+
+The video codec to use for encoding. Common options: libvpx-vp9 (CPU, BSD-licensed, default), libvpx (CPU, BSD-licensed, VP8). Any codec the local FFmpeg supports can be used, but the AIPerf container ships a minimal FFmpeg build limited to VP8/VP9 video with Vorbis/Opus audio; codecs such as libx264 or h264_nvenc require an FFmpeg build that includes them.
+<br/>_Default: `libvpx-vp9`_
+
+#### `--video-audio-sample-rate` `<float>`
+
+Audio sample rate in Hz or kHz for the embedded audio track. Common values: 8/8000 (telephony), 16/16000 (speech), 44.1/44100 (CD quality), 48/48000 (professional). Higher sample rates increase audio fidelity and file size.
+<br/>_Constraints: ≥ 8, ≤ 96000_
+<br/>_Default: `44100`_
+
+#### `--video-audio-num-channels` `<int>`
+
+Number of audio channels to embed in generated video files. 0 = disabled (no audio track, default), 1 = mono, 2 = stereo. When set to 1 or 2, a Gaussian noise audio track matching the video duration is muxed into each video via FFmpeg.
+<br/>_Constraints: ≥ 0, ≤ 2_
+<br/>_Default: `0`_
+
+#### `--video-audio-codec` `<str>`
+
+Audio codec for the embedded audio track. If not specified, auto-selects based on video format: libopus for MP4, libvorbis for WebM. Options: libvorbis, libopus, aac. The AIPerf container ships only libvorbis and libopus; aac requires an FFmpeg build that includes an AAC encoder. libopus always encodes at 48 kHz, so any --video-audio-sample-rate is resampled during muxing.
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `aac` |  | AAC codec. Not built into the AIPerf container's FFmpeg; selecting it requires an FFmpeg build that includes an AAC encoder. |
+| `libvorbis` |  | Vorbis codec. Default for WebM containers. |
+| `libopus` |  | Opus codec. Default for MP4 containers. Always encodes at 48 kHz regardless of the requested sample rate. |
+
+#### `--video-audio-depth` `<str>`
+
+Audio bit depth for the embedded audio track. Supported values: 8, 16, 24, or 32 bits. Higher bit depths provide greater dynamic range but increase file size.
+<br/>_Default: `16`_
+
+### Rankings
+
+#### `--rankings-passages-mean` `<int>`
+
+Mean number of passages to include per ranking request. For `rankings` endpoint type, each request contains a query and multiple passages to rank. Passages follow normal distribution around this mean (±`--rankings-passages-stddev`). Higher values test ranking at scale but increase request payload size and processing time.
+<br/>_Constraints: ≥ 1_
+<br/>_Default: `1`_
+
+#### `--rankings-passages-stddev` `<int>`
+
+Standard deviation for number of passages per ranking request. Creates variability in ranking workload complexity. Passage counts follow normal distribution. Set to 0 for uniform passage counts across all requests.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0`_
+
+#### `--rankings-passages-prompt-token-mean` `<int>`
+
+Mean token length for each passage in ranking requests. Passages are synthetically generated text with lengths following normal distribution around this mean (±`--rankings-passages-prompt-token-stddev`). Longer passages increase input processing demands and request size.
+<br/>_Constraints: ≥ 1_
+<br/>_Default: `550`_
+
+#### `--rankings-passages-prompt-token-stddev` `<int>`
+
+Standard deviation for passage token lengths in ranking requests. Creates variability in passage sizes, simulating realistic heterogeneous document collections. Token lengths follow normal distribution. Set to 0 for uniform passage lengths.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0`_
+
+#### `--rankings-query-prompt-token-mean` `<int>`
+
+Mean token length for query text in ranking requests. Each ranking request contains one query and multiple passages. Queries are synthetically generated with lengths following normal distribution around this mean (±`--rankings-query-prompt-token-stddev`).
+<br/>_Constraints: ≥ 1_
+<br/>_Default: `550`_
+
+#### `--rankings-query-prompt-token-stddev` `<int>`
+
+Standard deviation for query token lengths in ranking requests. Creates variability in query complexity, simulating realistic user search patterns. Token lengths follow normal distribution. Set to 0 for uniform query lengths.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0`_
+
+### Synthesis
+
+#### `--synthesis-speedup-ratio` `<float>`
+
+Multiplier for timestamp scaling in synthesized traces.
+<br/>_Constraints: ≥ 0.0_
+<br/>_Default: `1.0`_
+
+#### `--synthesis-prefix-len-multiplier` `<float>`
+
+Multiplier for core prefix branch lengths in radix tree.
+<br/>_Constraints: ≥ 0.0_
+<br/>_Default: `1.0`_
+
+#### `--synthesis-prefix-root-multiplier` `<int>`
+
+Number of independent radix trees to distribute traces across.
+<br/>_Constraints: ≥ 1_
+<br/>_Default: `1`_
+
+#### `--synthesis-prompt-len-multiplier` `<float>`
+
+Multiplier for leaf path (unique prompt) lengths.
+<br/>_Constraints: ≥ 0.0_
+<br/>_Default: `1.0`_
+
+#### `--synthesis-output-len-multiplier` `<float>`
+
+Multiplier for output lengths in synthesized traces.
+<br/>_Constraints: ≥ 0.0_
+<br/>_Default: `1.0`_
+
+#### `--synthesis-max-isl` `<int>`
+
+Maximum input sequence length for filtering. Traces with input_length > max_isl are skipped.
+<br/>_Constraints: ≥ 1_
+
+#### `--synthesis-max-osl` `<int>`
+
+Maximum output sequence length cap for top-level (parent) turns. Turns with output_length > max_osl are capped to max_osl. Subagent child turns are intentionally uncapped so their decode load stays faithful; flat-chain sidecars still honor the cap.
+<br/>_Constraints: ≥ 1_
+
+### Load Generator
+
+#### `--benchmark-duration` `<str>`
+
+Maximum benchmark runtime in seconds. When set, AIPerf stops issuing new requests after this duration, Responses received within `--benchmark-grace-period` after duration ends are included in metrics. Pass a comma-separated list (e.g. `--benchmark-duration 30,60,120`) to sweep over multiple durations; the converter promotes the list to a sweep on phases.profiling.duration before AIPerfConfig validation.
+
+#### `--benchmark-grace-period` `<float>`
+
+The grace period in seconds to wait for responses after benchmark duration ends. Only applies when --benchmark-duration is set. Responses received within this period are included in metrics. Use 'inf' to wait indefinitely for all responses.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `30.0`_
+
+#### `--concurrency` `<str>`
+
+Number of concurrent requests to maintain. AIPerf issues a new request immediately when one completes, maintaining this level of in-flight requests. Can be combined with `--request-rate` to control the request rate. Pass a comma-separated list (e.g. `--concurrency 10,20,30`) to sweep over multiple concurrencies; the converter promotes the list to a sweep before AIPerfConfig validation.
+
+#### `--prefill-concurrency` `<str>`
+
+Max concurrent requests waiting for first token (prefill phase). Limits how many requests can be in the prefill/prompt-processing stage simultaneously. Pass a comma-separated list (e.g. `--prefill-concurrency 1,2,4`) to sweep over multiple values; the converter promotes the list to a sweep before AIPerfConfig validation.
+
+#### `--request-rate` `<str>`
+
+Target request rate in requests per second. AIPerf generates request timing according to `--request-rate-mode` to achieve this average rate. Can be combined with `--concurrency` to control the number of concurrent requests. Supports fractional rates (e.g., `0.5` = 1 request every 2 seconds). Pass a comma-separated list (e.g. `--request-rate 10,20,50`) to sweep over multiple rates; the converter promotes the list to a sweep before AIPerfConfig validation.
+
+#### `--arrival-pattern`, `--request-rate-mode` `<str>`
+
+Sets the arrival pattern for the load generated by AIPerf. Valid values: constant, poisson, gamma. `constant`: Generate requests at a fixed rate. `poisson`: Generate requests using a poisson distribution. `gamma`: Generate requests using a gamma distribution with tunable smoothness.
+<br/>_Choices: [`concurrency_burst`, `constant`, `gamma`, `poisson`]_
+<br/>_Default: `poisson`_
+
+#### `--arrival-smoothness`, `--vllm-burstiness` `<float>`
+
+Smoothness parameter for gamma distribution arrivals (--arrival-pattern gamma). Controls the shape of the arrival pattern: - 1.0: Poisson-like (exponential inter-arrivals, default) - &lt;1.0: Bursty/clustered arrivals (higher variance) - >1.0: Smooth/regular arrivals (lower variance) Compatible with vLLM's --burstiness parameter (same value = same distribution).
+<br/>_Constraints: > 0_
+
+#### `--request-count`, `--num-requests` `<str>`
+
+The maximum number of requests to send. If not set, will be automatically determined based on the timing mode and dataset size. For synthetic datasets, this will be `max(10, concurrency * 2)`. Pass a comma-separated list (e.g. `--request-count 100,500,1000`) to sweep over multiple request counts; the converter promotes the list to a sweep on phases.profiling.requests before AIPerfConfig validation.
+
+#### `--concurrency-ramp-duration` `<float>`
+
+Duration in seconds to ramp session concurrency from 1 to target. Useful for gradual warm-up of the target system.
+<br/>_Constraints: > 0_
+
+#### `--prefill-concurrency-ramp-duration` `<float>`
+
+Duration in seconds to ramp prefill concurrency from 1 to target.
+<br/>_Constraints: > 0_
+
+#### `--request-rate-ramp-duration` `<float>`
+
+Duration in seconds to ramp request rate from a proportional minimum to target. Start rate is calculated as target * (update_interval / duration), ensuring correct behavior for target rates below 1 QPS. Useful for gradual warm-up of the target system.
+<br/>_Constraints: > 0_
+
+#### `--request-rate-series` `<str>`
+
+JSON file containing request-rate points for piecewise-linear request-rate control.
+
+#### `--failed-request-threshold` `<float>`
+
+Abort the run early when (failed_records / total_records) exceeds this ratio. Default None disables the check. Only PROFILING-phase records count toward the ratio. A grace floor of max(concurrency, 10) records must accumulate before the check is armed, so a single early failure cannot kill the run. When the threshold is exceeded a PROFILE_CANCEL is broadcast: in-flight requests drain via the normal cancel path, partial results are still aggregated, and the run exits non-zero. Pairs with the AGENTIC_REPLAY context-overflow drop in record_processor_service so the rate measures real failures only.
+<br/>_Constraints: ≥ 0.0, ≤ 1.0_
+
+#### `--trajectory-start-min-ratio` `<float>`
+
+AGENTIC_REPLAY only: lower bound (inclusive) on the random start position within each trajectory, expressed as a fraction of the trace's total turn count. Sampled per trajectory at trajectory-build time; deterministic given --random-seed.
+<br/>_Constraints: ≥ 0.0, ≤ 1.0_
+<br/>_Default: `0.25`_
+
+#### `--trajectory-start-max-ratio` `<float>`
+
+AGENTIC_REPLAY only: upper bound (inclusive) on the random start position within each trajectory, expressed as a fraction of the trace's total turn count. The effective per-trace ceiling is min(int(max_ratio * n), n - 2) so at least one profile turn remains after warmup.
+<br/>_Constraints: ≥ 0.0, ≤ 1.0_
+<br/>_Default: `0.75`_
+
+#### `--burst-phase-starts`
+
+AGENTIC_REPLAY only: collapse the WARMUP-start and PROFILING-start dispatches into synchronized bursts instead of spreading them by each request's recorded offset from t*. By default (False) the phase starts are SPREAD: WARMUP requests are aligned globally so every trajectory reaches its t* at the same instant (the warmup end), and each lane's first PROFILING request waits out its recorded gap after t* -- reproducing the recorded arrival pattern at both phase boundaries. The rest of the replay (inter-turn delays) is timing-faithful regardless of this flag; it governs ONLY the burst-vs-spread of the two phase starts. Pass --burst-phase-starts to fire each phase's first requests together (faster concurrency ramp, synchronized start), e.g. for a throughput-oriented run rather than a faithful arrival replay.
+<br/>_Flag (no value required)_
+
+#### `--trace-idle-gap-cap-seconds` `<float>`
+
+Hard ceiling (seconds) for idle gaps within each individual trace. For Weka trace replay, AIPerf looks at all parent and subagent request submission timestamps within one root trace, compresses long gaps between consecutive request submissions, and derives turn delays from the compressed per-trace timeline. Original request api_time values are not used to decide these idle gaps. When set for Weka, this takes precedence over `--inter-turn-delay-cap-seconds` so individual parent/subagent-line delays are not separately capped. Defaults to None (no per-trace idle-gap compression).
+<br/>_Constraints: ≥ 0.0_
+
+#### `--system-idle-gap-cap-seconds` `<float>`
+
+AGENTIC_REPLAY only: maximum time in seconds the replay may remain globally idle while future requests are scheduled. When no requests are in flight or ready, all pending request timers shift earlier uniformly so the next request arrives within this limit. Per-trace timing is otherwise preserved. None disables the cap.
+<br/>_Constraints: ≥ 0.0_
+
+### Scenario
+
+#### `--scenario` `<str>`
+
+Lock all benchmark invariants for a named scenario (e.g. 'inferencex-agentx-mvp'). Conflicts with the locked invariants raise ScenarioLockError at startup unless --unsafe-override is also passed. Distinct from the sweep ``scenarios`` strategy (hand-picked named runs).
+
+#### `--unsafe-override`
+
+Convert scenario lock errors to warnings; stamps submission_valid=false in the aggregate output. No-op without --scenario.
+<br/>_Flag (no value required)_
+
+### Warmup
+
+#### `--warmup-request-count`, `--num-warmup-requests` `<int>`
+
+The maximum number of warmup requests to send before benchmarking. If not set and no --warmup-duration is set, then no warmup phase will be used.
+<br/>_Constraints: > 0_
+
+#### `--warmup-duration` `<float>`
+
+The maximum duration in seconds for the warmup phase. If not set, it will use the `--warmup-request-count` value. If neither are set, no warmup phase will be used.
+<br/>_Constraints: > 0_
+
+#### `--agentic-cache-warmup-duration` `<float>`
+
+Additional agentic replay warmup duration in seconds. After the normal snapshot warmup drains, AIPerf continues the live trajectories without recorded idle delays and with one-token outputs, then drains and resumes profiling from the resulting trajectory state using each live stream's residual next-turn delay.
+<br/>_Constraints: > 0_
+
+#### `--agentic-warmup-grace-period` `<float>`
+
+AGENTIC_REPLAY only: grace period in seconds the auto-synthesized warmup barrier waits for in-flight priming requests after the warmup burst sends. The agentic warmup is synthesized from the profiling phase rather than a user-declared warmup phase, so it does NOT honor `--warmup-grace-period` (which requires `--warmup-duration`). If not set, the warmup barrier waits indefinitely until every primed trajectory returns.
+<br/>_Constraints: ≥ 0_
+
+#### `--num-warmup-sessions` `<int>`
+
+The number of sessions to use for the warmup phase. If not set, it will use the `--warmup-request-count` value.
+<br/>_Constraints: ≥ 1_
+
+#### `--warmup-concurrency` `<int>`
+
+The concurrency value to use for the warmup phase. If not set, it will use the `--concurrency` value.
+<br/>_Constraints: ≥ 1_
+
+#### `--warmup-prefill-concurrency` `<int>`
+
+The prefill concurrency value to use for the warmup phase. If not set, it will use the `--prefill-concurrency` value.
+<br/>_Constraints: ≥ 1_
+
+#### `--warmup-request-rate` `<float>`
+
+The request rate to use for the warmup phase. If not set, it will use the `--request-rate` value.
+<br/>_Constraints: > 0_
+
+#### `--warmup-arrival-pattern` `<str>`
+
+The arrival pattern to use for the warmup phase. If not set, it will use the `--arrival-pattern` value. Valid values: constant, poisson, gamma.
+
+#### `--warmup-grace-period` `<float>`
+
+The grace period in seconds to wait for responses after warmup phase ends. Only applies when warmup is enabled. Responses received within this period are included in warmup completion. If not set, waits indefinitely for all warmup responses.
+<br/>_Constraints: ≥ 0_
+
+#### `--warmup-concurrency-ramp-duration` `<float>`
+
+Duration in seconds to ramp warmup session concurrency from 1 to target. If not set, uses `--concurrency-ramp-duration` value.
+<br/>_Constraints: > 0_
+
+#### `--warmup-prefill-concurrency-ramp-duration` `<float>`
+
+Duration in seconds to ramp warmup prefill concurrency from 1 to target. If not set, uses `--prefill-concurrency-ramp-duration` value.
+<br/>_Constraints: > 0_
+
+#### `--warmup-request-rate-ramp-duration` `<float>`
+
+Duration in seconds to ramp warmup request rate from a proportional minimum to target. Start rate is calculated as target * (update_interval / duration). If not set, uses `--request-rate-ramp-duration` value.
+<br/>_Constraints: > 0_
+
+### User-Centric Rate
+
+#### `--user-centric-rate` `<float>`
+
+Enable user-centric rate limiting mode with the specified request rate (QPS). Each user has a gap = num_users / qps between turns. Users block on their previous turn (no interleaving within a user). New users are spawned on a fixed schedule to maintain steady-state throughput. Designed for KV cache benchmarking with realistic multi-user patterns. Requires --num-users to be set.
+<br/>_Constraints: > 0_
+
+#### `--num-users` `<str>`
+
+The number of initial users to use for --user-centric-rate mode. Pass a comma-separated list (e.g. `--num-users 4,8,16`) to sweep over user counts; the converter promotes the list to a sweep on phases.profiling.users before AIPerfConfig validation.
+
+### Request Cancellation
+
+#### `--request-cancellation-rate` `<float>`
+
+Percentage (0-100) of requests to cancel for testing cancellation handling. Cancelled requests are sent normally but aborted after `--request-cancellation-delay` seconds. Useful for testing graceful degradation and resource cleanup.
+<br/>_Constraints: > 0.0, ≤ 100.0_
+
+#### `--request-cancellation-delay` `<float>`
+
+Seconds to wait after the request is fully sent before cancelling. A delay of 0 means 'send the full request, then immediately disconnect'. Requires --request-cancellation-rate to be set.
+<br/>_Constraints: ≥ 0.0_
+<br/>_Default: `0.0`_
+
+### Output
+
+#### `--output-artifact-dir`, `--artifact-dir` `<str>`
+
+Output directory for all benchmark artifacts including metrics (`.csv`, `.json`, `.jsonl`), raw data (`_raw.jsonl`), GPU telemetry (`_gpu_telemetry.jsonl`), and time-sliced metrics (`_timeslices.csv/json`). Directory created if it doesn't exist. All output file paths are constructed relative to this directory.
+<br/>_Default: `artifacts`_
+
+#### `--profile-export-prefix`, `--profile-export-file` `<str>`
+
+Base filename for ALL exported files. With prefix='foo' every output becomes `foo.csv`, `foo.json`, `foo_timeslices.{csv,json}`, `foo.jsonl`, `foo_raw.jsonl`, `foo_gpu_telemetry.jsonl`, and `foo_server_metrics.{jsonl,json,csv,parquet}`. When unset (the default), historical per-file names are used: `profile_export_aiperf.{csv,json}` for the summary, `profile_export.jsonl` and `profile_export_raw.jsonl` for records, `gpu_telemetry_export.jsonl`, and `server_metrics_export.*`. Known suffixes (e.g. `_raw.jsonl`, `_timeslices.csv`, `_server_metrics.parquet`) are stripped from the supplied value.
+
+#### `--export-level`, `--profile-export-level` `<str>`
+
+Controls which output files are generated. `summary`: Only aggregate metrics files (`.csv`, `.json`). `records`: Includes per-request metrics (`.jsonl`). `raw`: Includes raw request/response data (`_raw.jsonl`).
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `summary` |  | Export only aggregated/summarized metrics (most compact) |
+| `records` | _default_ | Export per-record metrics after aggregation with display unit conversion (CLI default) |
+| `raw` |  | Export raw parsed records with full request/response data (most detailed) |
+
+#### `--slice-duration` `<float>`
+
+Duration in seconds for time-sliced metric analysis. When set, AIPerf divides the benchmark timeline into fixed-length windows and computes metrics separately for each window. This enables analysis of performance trends and variations over time (e.g., warmup effects, degradation under sustained load).
+<br/>_Constraints: > 0_
+
+#### `--auto-plot`, `--no-auto-plot`
+
+Auto-invoke `aiperf plot` against the artifact directory after the benchmark completes. None = defer to recipe default (False if no recipe). True/False = explicit override. Failures are logged but do not fail the command unless --plot-required is set.
+
+#### `--plot-required`
+
+Treat auto-plot failures as fatal: re-raise so `aiperf profile` exits non-zero. Only meaningful when auto-plot is on. Default False = warn and continue.
+<br/>_Flag (no value required)_
+
+#### `--export-outputs-json`
+
+Export generated response text to outputs.json after the run. When enabled, the raw generated-text payload for each request is written to an outputs.json file in the artifact directory.
+<br/>_Flag (no value required)_
+
+#### `--otel-url` `<str>`
+
+OTLP/HTTP metrics endpoint URL.
+
+#### `--stream` `<list>`
+
+Select which AIPerf telemetry domains to stream over OTel. Valid values: 'metrics', 'timing', or 'default'. 'default' streams both metrics and timing. Examples: --stream metrics | --stream timing | --stream metrics timing.
+

+
+#### `--mlflow-parent-run-id` `<str>`
+
+Optional MLflow parent run ID.
+
+#### `--mlflow-artifact-glob` `<list>`
+
+Artifact glob overrides for MLflow upload. Can be specified multiple times or as a comma-separated list.
+
+#### `--wandb-project` `<str>`
+
+Weights & Biases project name. Setting this enables wandb export.
+
+#### `--wandb-entity` `<str>`
+
+Weights & Biases entity (team or user). Defaults to the API key's default entity.
+
+#### `--wandb-run-name` `<str>`
+
+Weights & Biases run name.
+
+#### `--wandb-tag` `<list>`
+
+Additional Weights & Biases run tags to attach on upload. Can be specified multiple times or as a comma-separated list.
+
+### HTTP Trace
+
+#### `--export-http-trace`
+
+Include HTTP trace data (timestamps, chunks, headers, socket info) in profile_export.jsonl. Computed metrics (http_req_duration, http_req_waiting, etc.) are always included regardless of this setting. See the HTTP Trace Metrics guide for details on trace data fields.
+<br/>_Flag (no value required)_
+
+#### `--show-trace-timing`
+
+Display HTTP trace timing metrics in the console at the end of the benchmark. Shows detailed timing breakdown: blocked, DNS, connecting, sending, waiting (TTFB), receiving, and total duration following k6 naming conventions.
+<br/>_Flag (no value required)_
+
+### Server Metrics
+
+#### `--server-metrics` `<list>`
+
+Server metrics collection (ENABLED BY DEFAULT). Automatically collects from inference endpoint base_url + `/metrics`. Optionally specify additional custom Prometheus-compatible endpoint URLs (e.g., http://node1:8081/metrics, http://node2:9090/metrics). Use `--no-server-metrics` to disable collection. Example: `--server-metrics node1:8081 node2:9090/metrics` for additional endpoints.
+
+#### `--no-server-metrics`
+
+Disable server metrics collection entirely.
+
+#### `--server-metrics-formats` `<list>`
+
+Specify which output formats to generate for server metrics. Multiple formats can be specified (e.g., `--server-metrics-formats json csv parquet`).
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `json` | _default_ | Export aggregated statistics in JSON hybrid format with metrics keyed by name. Best for: Programmatic access, CI/CD pipelines, automated analysis. |
+| `csv` | _default_ | Export aggregated statistics in CSV tabular format organized by metric type. Best for: Spreadsheet analysis, Excel/Google Sheets, pandas DataFrames. |
+| `jsonl` |  | Export raw time-series records in line-delimited JSON format. Best for: Time-series analysis, debugging, visualizing metric evolution. Warning: Can generate very large files for long-running benchmarks. |
+| `parquet` |  | Export raw time-series data with delta calculations in Parquet columnar format. Best for: Analytics with DuckDB/pandas/Polars, efficient storage, SQL queries. Includes cumulative deltas from reference point for counters and histograms. |
+
+### Network Latency
+
+#### `--network-latency-automatic`
+
+Automatically measure network latency (DISABLED BY DEFAULT). Opens a fresh TCP connection to the endpoint throughout the run, measures the handshake RTT, and subtracts the mean from request-start-anchored latency metrics (request_latency, time_to_first_token, time_to_first_output_token). Raw metrics are preserved; adjusted values are emitted as separate network_adjusted_* metrics plus a network_rtt summary. Mutually exclusive with --network-latency-mean.
+<br/>_Flag (no value required)_
+
+#### `--network-latency-mean` `<float>`
+
+Set a fixed mean network RTT in milliseconds to subtract, bypassing active probing. Implicitly enables network latency adjustment. Mutually exclusive with --network-latency-automatic.
+<br/>_Constraints: ≥ 0.0_
+
+#### `--network-latency-ping-interval` `<float>`
+
+Seconds between TCP-handshake RTT probes during profiling (default: 1.0s). Only applies with --network-latency-automatic.
+<br/>_Constraints: > 0.0_
+
+### GPU Telemetry
+
+#### `--gpu-telemetry` `<list>`
+
+Enable GPU telemetry console display and optionally specify: (1) 'pynvml' or 'amdsmi' to use a local GPU library instead of DCGM HTTP endpoints, (2) 'dashboard' for realtime dashboard mode, (3) custom DCGM exporter URLs (e.g., http://node1:9401/metrics), (4) custom metrics CSV file (e.g., custom_gpu_metrics.csv). Default: DCGM mode with localhost:9400 and localhost:9401 endpoints. Examples: --gpu-telemetry pynvml | --gpu-telemetry amdsmi | --gpu-telemetry dashboard node1:9400.
+
+#### `--no-gpu-telemetry`
+
+Disable GPU telemetry collection entirely.
+
+### UI
+
+#### `--ui-type`, `--ui` `<str>`
+
+Select the user interface type for displaying benchmark progress. `dashboard` shows real-time metrics in a Textual TUI, `simple` uses TQDM progress bars, `none` disables UI completely. Defaults to `dashboard` in interactive terminals, `none` when not a TTY (e.g., piped or redirected output). Automatically set to `simple` when using `--verbose` or `--extra-verbose` in a TTY.
+<br/>_Choices: [`dashboard`, `none`, `simple`]_
+<br/>_Default: `dashboard`_
+
+### Multi-Run
+
+#### `--num-profile-runs` `<int>`
+
+Number of profile runs to execute for confidence reporting. Must be between 1 and 10. When set to 1 (default), runs a single benchmark. When set to >1, runs multiple benchmarks and computes aggregate statistics (mean, std, confidence intervals, coefficient of variation) across runs. Useful for quantifying variance and establishing confidence in results.
+<br/>_Constraints: ≥ 1, ≤ 10_
+<br/>_Default: `1`_
+
+#### `--profile-run-cooldown-seconds` `<float>`
+
+Cooldown duration in seconds between profile runs. Only applies when --num-profile-runs > 1. Allows the system to stabilize between runs (e.g., clear caches, cool down GPUs). Default is 0 (no cooldown).
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0.0`_
+
+#### `--confidence-level` `<float>`
+
+Confidence level for computing confidence intervals (0-1). Only applies when --num-profile-runs > 1. Common values: 0.90 (90%), 0.95 (95%, default), 0.99 (99%). Higher values produce wider confidence intervals.
+<br/>_Constraints: > 0, &lt; 1_
+<br/>_Default: `0.95`_
+
+#### `--profile-run-disable-warmup-after-first`, `--no-profile-run-disable-warmup-after-first`
+
+Disable warmup for profile runs after the first. Only applies when --num-profile-runs > 1. When True (default), only the first run includes warmup, subsequent runs measure steady-state performance for more accurate aggregate statistics. When False, all runs include warmup (useful for long cooldown periods or when testing cold-start performance).
+<br/>_Default: `True`_
+
+#### `--set-consistent-seed`, `--no-set-consistent-seed`
+
+Automatically set random seed for consistent workloads across runs. Only applies when --num-profile-runs > 1. When True (default), automatically sets --random-seed=42 if not specified, ensuring identical workloads across all runs for valid statistical comparison. When False, preserves None seed, resulting in different workloads per run (not recommended for confidence reporting as it produces invalid statistics). If --random-seed is explicitly set, that value is always used regardless of this setting.
+<br/>_Default: `True`_
+
+#### `--vary-seed-per-trial`, `--no-vary-seed-per-trial`
+
+When True, derive a distinct seed for each trial of a variation via SHA-256 over (envelope_seed, variation.label, trial). When False (default), all trials of a variation share the same seed, giving pure-runtime variance for confidence intervals. Enable when you want trials to also sample different inputs (captures end-to-end variance at the cost of conflating input noise with runtime noise in the resulting confidence statistics).
+
+#### `--convergence-metric` `<str>`
+
+Target metric name for adaptive convergence stopping. When set with --num-profile-runs > 1, enables adaptive mode that stops early once the metric stabilizes according to --convergence-mode. Uses --num-profile-runs as the maximum run cap. Example metrics: time_to_first_token, request_latency, inter_token_latency.
+
+#### `--convergence-stat` `<str>`
+
+Statistic to evaluate for convergence when using ci_width or cv mode. Common values: avg, p50, p90, p95, p99. Only applies when --convergence-metric is set.
+<br/>_Choices: [`avg`, `p50`, `p90`, `p95`, `p99`, `min`, `max`]_
+<br/>_Default: `avg`_
+
+#### `--convergence-threshold` `<float>`
+
+Threshold for convergence detection. For ci_width mode: maximum CI width as a fraction of the mean. For cv mode: maximum coefficient of variation. For distribution mode: KS test p-value threshold. When unset, each mode uses its own algorithm-specific default. Only applies when --convergence-metric is set.
+<br/>_Constraints: > 0, &lt; 1_
+
+#### `--convergence-mode` `<str>`
+
+Statistical method for convergence detection. ci_width: Stop when Student's t confidence interval width relative to mean is below threshold. cv: Stop when coefficient of variation (std/mean) is below threshold. distribution: Stop when KS test p-value indicates latest run matches prior runs (requires --export-level records or --export-level raw; rejected with --export-level summary). Only applies when --convergence-metric is set.
+<br/>_Choices: [`ci_width`, `cv`, `distribution`]_
+<br/>_Default: `ci_width`_
+
+#### `--parameter-sweep-cooldown-seconds` `<float>`
+
+Cooldown seconds between sweep variations (e.g. between --concurrency 10 and --concurrency 20). Honored by MultiRunOrchestrator when iterating plan.configs. Default 0.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0.0`_
+
+#### `--parameter-sweep-same-seed`, `--no-parameter-sweep-same-seed`
+
+If true, every sweep variation reuses the same random seed (correlated comparisons). If false (default), each variation derives a unique seed `base_seed + variation.index` so independent draws exercise different inputs. Requires --random-seed when true.
+
+#### `--parameter-sweep-mode` `<str>`
+
+Execution order for sweep + multi-trial composition. 'repeated' (default) iterates trials as the outer loop and variations as the inner loop, so all variations run within trial 1, then within trial 2, etc. 'independent' inverts the loops: all trials at one variation complete before the next variation starts. Both modes produce the same total runs, only the artifact-path layout and submit order differ.
+<br/>_Choices: [`independent`, `repeated`]_
+<br/>_Default: `repeated`_
+
+#### `--sweep-type` `<str>`
+
+Topology used when multiple CLI magic-list flags (--concurrency, --request-rate, --isl, --osl, ...) are passed together. 'grid' (default) takes the Cartesian product of all lists; 'zip' pairs them element-wise (all lists must have equal length, like the YAML `sweep: {type: zip}` block). Ignored when only one magic-list flag is set or when the sweep is declared in YAML.
+<br/>_Default: `grid`_
+
+#### `--no-sweep-table`
+
+Suppress the per-cell streaming sweep table during multi-variation sweeps. Auto-suppressed when stdout is non-interactive, when the dashboard UI is active, or for single-cell sweeps.
+
+#### `--search-space` `<list>`
+
+Adaptive-search space dimensions. Repeatable. Each value is 'path:lo,hi[:kind]', e.g. 'phases.profiling.concurrency:1,1000:int'. Mutually exclusive with magic-list flags (--concurrency 10,20,30) and with explicit sweep blocks. See docs/sweeping/bayesian-optimization.md.
+
+#### `--search-metric` `<str>`
+
+Metric tag to optimize, e.g. 'output_token_throughput'. Required when --search-space is set. Must match a key in RunResult.summary_metrics produced by the run (NOT the flattened '_avg' / '_p99' aggregator-suffixed key).
+
+#### `--search-stat` `<str>`
+
+Statistic on the metric: avg / p50 / p90 / p95 / p99. Defaults to 'avg' when omitted (set by the CLIConfig -> AIPerfConfig converter).
+
+#### `--search-direction` `<str>`
+
+Optimization direction. Required when --search-space is set.
+
+#### `--search-max-iterations` `<int>`
+
+Maximum number of search iterations. Each iteration runs --num-profile-runs benchmarks. Required when --search-space is set.
+<br/>_Constraints: ≥ 2, ≤ 200_
+
+#### `--search-initial-points` `<int>`
+
+Random Sobol points before fitting the GP. Defaults to 5 when omitted. Must be &lt; --search-max-iterations.
+<br/>_Constraints: ≥ 1_
+
+#### `--search-random-seed` `<int>`
+
+Random seed for reproducible search trajectories. When unset, the planner uses non-deterministic randomness.
+<br/>_Constraints: ≥ 0_
+
+#### `--search-planner` `<str>`
+
+Outer-loop search planner plugin. Default `bayesian` is a curated Optuna preset that uses BoTorch qLogNEI/qLogNEHVI when the optional `botorch` extra is installed and otherwise falls back to Optuna TPE with a warning. `optuna` is the expert-mode alternative exposing `--optuna-sampler` (tpe / gp / botorch) and `--optuna-acquisition`. Explicit unavailable optional samplers raise. Third-party planners registered under the `search_planner` plugin category are accepted here. Only applies when --search-space is set.
+<br/>_Choices: [`bayesian`, `monotonic_sla`, `smooth_isotonic`, `optuna`]_
+
+#### `--optuna-sampler` `<str>`
+
+Optuna sampler selection. Only consulted when --search-planner=optuna. ``botorch`` is the preferred implicit default and requires the optional ``botorch`` extra; when the implicit default is unavailable, the planner warns and falls back to ``tpe``. Explicit ``botorch`` requests raise if the optional stack is unavailable. ``tpe`` is dep-light and ships with Optuna core. ``gp`` is Optuna's native GP-EI with inequality constraints (Optuna 4.2+) but requires ``torch``.
+
+#### `--optuna-acquisition` `<str>`
+
+Acquisition function override for the Optuna BoTorch sampler. Only consulted when --search-planner=optuna AND --optuna-sampler=botorch; rejected otherwise. ``None`` (default) lets Optuna pick (single-objective unconstrained -> LogEI per Optuna v4.x). ``logei``/``qlogei`` make that explicit. ``qnei`` selects plain noisy EI (Letham 2017). ``qlognei`` selects qLogNoisyExpectedImprovement (Ament 2023, https://arxiv.org/abs/2310.20708) -- BoTorch's strongly recommended modern noisy-EI default; requires ``botorch>=0.10``. Multi-objective variants (``qehvi``/``qnehvi``/``qlognehvi``) are accepted when ``objectives`` has length > 1; the planner rejects them on single-objective configs.
+
+#### `--optuna-terminator` `<str>`
+
+Optional posterior-regret stopping rule layered on top of the three-signal convergence check. Only consulted when --search-planner=optuna. ``regret`` selects Optuna's ``RegretBoundEvaluator`` (Makarova et al. 2022, https://proceedings.mlr.press/v188/makarova22a.html). ``emmr`` selects ``EMMREvaluator`` (Ishibashi et al. 2023, https://proceedings.mlr.press/v206/ishibashi23a.html). Both are in the same family as Wilson 2024's PRB stopping rule and ship in Optuna core (no extra dep). ``none`` (default) disables; convergence is then driven by --search-max-iterations / --improvement-patience / --plateau-cv only.
+
+#### `--search-percentile-pooling` `<str>`
+
+Percentile aggregation strategy when --search-stat is a percentile (p50/p90/p95/p99). ``mean`` (default) computes the BO objective as the arithmetic mean of per-trial percentiles across --num-profile-runs trials. ``pooled`` walks each trial's per-request profile_export.jsonl, accumulates raw samples, and computes ``np.percentile`` over the pooled bag -- exposing more tail mass than mean-of-percentiles (correct for SLO claims; same argmax for ranking on monotone problems). ``pooled`` requires --export-level records; if the JSONL is missing the planner falls back to mean with a one-time warning. Rejected when --search-stat is ``avg``.
+
+#### `--bo-constraint-mode` `<str>`
+
+Deprecated and ignored. The bayesian preset and the optuna expert mode both use Optuna's native ``constraints_func`` (Letham et al. 2019, arXiv:1706.07094), which subsumes both the soft-penalty and EIC formulations. Accepted for backwards compatibility but has no effect: the value flows through ``_converter_optionals._SWEEP_OPTIONAL_FIELDS`` to ``AdaptiveSearchSweep.constraint_mode`` (see ``aiperf.config.sweep.config``), and that field is not read by any planner.
+
+#### `--variant`, `--sweep-variant` `<list>`
+
+Repeatable: each occurrence describes one sweep variation. Format: '[name:] key=value, key=value, ...'. Keys are CLI flag names with the leading '--' stripped, in either kebab-case or snake_case (isl, osl, concurrency, request-rate / request_rate, request-count / request_count, benchmark-duration / benchmark_duration, ...). Multi-occurrence emits a ScenarioSweep. Mutually exclusive with magic-list flags, --search-recipe, and YAML-declared sweeps. Single-occurrence is rejected -- use the standalone --isl / --osl / --concurrency flags for a one-off.
+
+#### `--search-sla` `<list>`
+
+SLA filter to attach to the adaptive-search or grid path. Format: 'metric_tag:stat:op:threshold'. Stat in {avg, min, max, p1, p5, p10, p25, p50, p75, p90, p95, p99}; op in {lt, le, gt, ge}; threshold is a float in the metric's native unit. For request_error_rate, 1 means 1% (percentage points), unlike --error-rate-sla, which accepts a fraction. Repeatable. Example: --search-sla 'time_to_first_token:p95:lt:200' --search-sla 'request_error_rate:avg:lt:1'. Composes with recipe-named SLA flags (--ttft-sla-ms etc.); the final filter list is recipe filters first, then --search-sla filters in CLI order.
+
+#### `--search-sla-tier` `<list>`
+
+Multi-tier SLO grouping flag. Each invocation defines one tier of SLA filters. Format: 'LABEL:FILTER[,FILTER...]' or 'FILTER[,FILTER...]' (auto-labels tier_1, tier_2, ...). Requires 2-10 invocations. Example: --search-sla-tier 'fast:output_token_throughput:avg:gt:300,time_to_first_token:p95:lt:5000' --search-sla-tier 'standard:output_token_throughput:avg:gt:100,time_to_first_token:p95:lt:10000'. When used, all --search-sla filters are still parsed and compose with tier definitions.
+
+#### `--search-recipe` `<str>`
+
+Named search-recipe preset that expands to an adaptive-search or sweep block. Mutually exclusive with explicit --search-* flags. Recipes are registered under the search_recipe plugin category. Example: --search-recipe max-throughput-ttft-sla --ttft-sla-ms 200.
+
+#### `--ttft-sla-ms` `<float>`
+
+Time-to-first-token SLA threshold in milliseconds. Required by TTFT-SLA recipes (e.g. max-throughput-ttft-sla); ignored otherwise. Must be > 0 — a 0 or negative threshold yields an unsatisfiable filter.
+<br/>_Constraints: > 0_
+
+#### `--isl-osl-pairs` `<str>`
+
+Paired ISL/OSL workload shapes for the pareto-sweep recipe, e.g. '128/128,512/256,2048/512'. Each pair is '&lt;isl>/&lt;osl>' with positive ints; pairs are comma-separated and whitespace-tolerant. Recipe-only flag; ignored unless --search-recipe pareto-sweep is set.
+
+#### `--itl-sla-ms` `<float>`
+
+Inter-token-latency SLA threshold in milliseconds. Required by ITL-SLA recipes (e.g. max-throughput-itl-sla); ignored otherwise. Must be > 0 — a 0 or negative threshold yields an unsatisfiable filter.
+<br/>_Constraints: > 0_
+
+#### `--tpot-sla-ms` `<float>`
+
+Time-per-output-token SLA threshold in milliseconds. Maps to the `inter_token_latency` metric tag (TPOT and ITL are equivalent in this codebase). Consumed by the max-concurrency-under-sla and max-goodput-under-slo recipes; ignored otherwise. Streaming required.
+<br/>_Constraints: > 0_
+
+#### `--e2e-sla-ms` `<float>`
+
+End-to-end request-latency SLA threshold in milliseconds (p99). Maps to the `request_latency` metric tag. Consumed by the max-concurrency-under-sla and max-goodput-under-slo recipes; ignored otherwise. Available without streaming.
+<br/>_Constraints: > 0_
+
+#### `--error-rate-sla` `<float>`
+
+Maximum acceptable request error rate as a fraction in (0, 1) (e.g. 0.05 = 5%). Maps to the `request_error_rate` metric tag (avg), converting the fraction to the metric's percentage-point scale. Consumed by the max-concurrency-under-sla recipe; ignored otherwise. Available without streaming.
+<br/>_Constraints: > 0, &lt; 1_
+
+#### `--slo-attainment-fraction` `<float>`
+
+Minimum fraction of requests that must satisfy ALL configured per-request SLOs (TTFT/TPOT/E2E) for a configuration to be considered feasible by the goodput recipe. Bounded in (0, 1]. Default 0.95 matches DistServe's canonical attainment-fraction convention (https://arxiv.org/pdf/2401.09670). Consumed by the max-goodput-under-slo recipe; ignored otherwise.
+<br/>_Constraints: > 0, ≤ 1_
+
+#### `--search-style` `<str>`
+
+Search strategy for the max-concurrency-under-sla recipe. 'smooth_isotonic' (default) runs PAVA + PCHIP smooth-isotonic regression-based 1D SLA-saturation search. 'monotonic' runs a 1D binary-search via the MonotonicSLASearchPlanner (~10-20 iterations). 'bo' runs penalty Bayesian Optimization (~30 iterations). 'optuna' runs the same penalty-BO formulation via the OptunaSearchPlanner (TPE/GP/BoTorch samplers; BoTorch requires the optional botorch extra). 'grid' runs a log-spaced 8-step sweep + sla_breach_knee post-process. Recipe-only flag; ignored unless --search-recipe max-concurrency-under-sla is set.
+
+#### `--degradation-threshold` `<float>`
+
+Relative latency degradation threshold for the concurrency-ramp recipe (e.g. 0.20 = 20%). The recipe's post-process handler reports the first concurrency where p99 latency exceeds baseline * (1 + threshold). Recipe-only flag; ignored unless --search-recipe concurrency-ramp is set.
+<br/>_Constraints: > 0, &lt; 1_
+
+#### `--degradation-metric-tag` `<str>`
+
+ConcurrencyRamp post-process: metric tag for knee detection (default: request_latency). Use, e.g., 'time_to_first_token' to detect the knee on TTFT instead of end-to-end request latency. Recipe-only flag; ignored unless --search-recipe concurrency-ramp is set.
+
+#### `--degradation-stat` `<str>`
+
+ConcurrencyRamp post-process: statistic for knee detection (default: p99). Recipe-only flag; ignored unless --search-recipe concurrency-ramp is set.

+<br/>_Constraints: ≥ 1_
+
+#### `--isl-steps` `<int>`
+
+Number of log-spaced steps for the prefill-ttft-curve recipe's ISL grid (default 8 when omitted). Must be >= 2 — a single-point ramp degenerates and post-process can't compute a baseline. Recipe-only flag.
+<br/>_Constraints: ≥ 2_
+
+#### `--concurrency-min` `<int>`
+
+Lower bound for the concurrency sweep axis used by concurrency-ramp and decode-itl-curve recipes (defaults: 1 for concurrency-ramp, 1 for decode-itl-curve). Must be &lt; --concurrency-max. Recipe-only flag.
+<br/>_Constraints: ≥ 1_
+
+#### `--concurrency-max` `<int>`
+
+Upper bound for the concurrency sweep axis used by concurrency-ramp and decode-itl-curve recipes (defaults: 1000 for concurrency-ramp, 200 for decode-itl-curve). Must be > --concurrency-min. Recipe-only flag.

+<br/>_Choices: [`mmlu`, `mmlu_pro`, `aime`, `hellaswag`, `bigbench`, `aime24`, `aime25`, `math_500`, `gsm8k`, `gpqa_diamond`, `lcb_codegeneration`]_
+
+#### `--accuracy-tasks` `<list>`

+<br/>_Flag (no value required)_
+
+### Service
+
+#### `--log-level` `<str>`
+
+Set the logging verbosity level. Controls the amount of output displayed during benchmark execution. Use `TRACE` for debugging ZMQ messages, `DEBUG` for detailed operation logs, or `INFO` (default) for standard progress updates.
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `TRACE` |  | Most verbose. Logs all operations including ZMQ messages and internal state changes. |
+| `DEBUG` |  | Detailed debugging information. Logs function calls and important state transitions. |
+| `INFO` | _default_ | General informational messages. Default level showing benchmark progress and results. |
+| `NOTICE` |  | Important informational messages that are more significant than INFO but not warnings. |
+| `WARNING` |  | Warning messages for potentially problematic situations that don't prevent execution. |
+| `SUCCESS` |  | Success messages for completed operations and milestones. |
+| `ERROR` |  | Error messages for failures that prevent specific operations but allow continued execution. |
+| `CRITICAL` |  | Critical errors that may cause the benchmark to fail or produce invalid results. |
+
+#### `-v`, `--verbose`
+
+Equivalent to `--log-level DEBUG`. Enables detailed logging output showing function calls and state transitions. Also automatically switches UI to `simple` mode for better console visibility. Does not include raw ZMQ message logging.

+Number of `RecordProcessor` services to spawn for parallel metric computation. Higher request rates require more processors to keep up with incoming records. If not specified, automatically determined based on worker count (typically 1-2 processors per 8 workers).
+<br/>_Constraints: ≥ 1_
+
+#### `--api-port` `<int>`
+
+AIPerf API port (enables HTTP + WebSocket endpoints).
+<br/>_Constraints: ≥ 1, ≤ 65535_
+
+#### `--api-host` `<str>`

+
+#### `--stats-interval` `<float>`
+
+Interval in seconds between realtime stats publishes (dashboards and the per-tick log block). 0 disables the log block while dashboards continue to poll. Defaults to 5s under --ui dashboard, 30s otherwise. Overrides AIPERF_UI_REALTIME_METRICS_INTERVAL.
+<br/>_Constraints: ≥ 0.0, ≤ 1000.0_
+
+### ZMQ Communication
+
+#### `--zmq-host` `<str>`
+
+Host address for internal ZMQ TCP communication between AIPerf services. Defaults to `127.0.0.1` (localhost) for single-machine deployments. For distributed setups, set to a reachable IP address. All internal service-to-service communication (message bus, dataset manager, workers) uses this host for TCP sockets.
+<br/>_Default: `127.0.0.1`_
+
+#### `--zmq-ipc-path` `<str>`
+
+Directory path for ZMQ IPC (Inter-Process Communication) socket files. When using IPC transport instead of TCP, AIPerf creates Unix domain socket files in this directory for faster local communication. Auto-generated in system temp directory if not specified. Only applicable when using IPC communication backend.
+
+#### `--zmq-dual-bind`
+
+Select the ZMQ dual-bind communication backend (IPC + TCP). All dual-bind knobs are cluster-managed; this flag only selects the discriminator and the converter routes downstream to the default.
+<br/>_Flag (no value required)_

+
+Path to kubeconfig file (defaults to ~/.kube/config or KUBECONFIG env).

+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `Always` |  | Every time the kubelet launches a container, it queries the registry to resolve the name to a digest. Uses cached image if digest matches, otherwise pulls the image. |
+| `Never` |  | The kubelet does not try fetching the image. Startup fails if the image is not already present locally. |
+| `IfNotPresent` |  | The image is pulled only if it is not already present locally. |
+
+#### `--total-workers` `<int>`
+
+Total number of workers, distributed across pods based on runtime.workersPerPod (default 10). E.g., --total-workers 50 = 5 pods × 10 workers. A total at or below runtime.workersPerPod runs on a single pod. Above it, a JobSet cannot express a partial final pod, so a total that is not a multiple of runtime.workersPerPod is rejected: --total-workers 25 is an error, use 20 or 30.
+<br/>_Constraints: > 0_

+```
+
+### Endpoint
+
+#### `-m`, `--model-names`, `--model` `<list>`
+
+Model name(s) to be benchmarked. Can be a comma-separated list or a single model name.
+
+#### `--model-selection-strategy` `<str>`
+
+When multiple models are specified, this is how a specific model should be assigned to a prompt. round_robin: nth prompt in the list gets assigned to n-mod len(models). random: assignment is uniformly random.
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `round_robin` | _default_ | Cycle through models in order. The nth prompt is assigned to model at index (n mod number_of_models). |
+| `random` |  | Randomly select a model for each prompt using uniform distribution. |
+| `weighted` |  | Select a model with probability proportional to a per-model weight. |
+
+#### `--custom-endpoint`, `--endpoint` `<str>`
+
+Set a custom API endpoint path (e.g., `/v1/custom`, `/my-api/chat`). By default, endpoints follow OpenAI-compatible paths like `/v1/chat/completions`. Use this option to override the default path for non-standard API implementations.
+
+#### `--endpoint-type` `<str>`
+
+The API endpoint type to benchmark. Determines request/response format and supported features. Common types: `chat` (multi-modal conversations), `embeddings` (vector generation), `completions` (text completion). See enum documentation for all supported endpoint types.
+<br/>_Choices: [`audio_transcription`, `chat`, `cohere_rankings`, `completions`, `responses`, `messages`, `chat_embeddings`, `embeddings`, `hf_tei_rankings`, `huggingface_generate`, `image_generation`, `image_edit`, `video_generation`, `image_retrieval`, `nim_embeddings`, `nim_rankings`, `solido_rag`, `raw`, `template`]_
+<br/>_Default: `chat`_
+
+#### `--streaming`
+
+Enable streaming responses. When enabled, the server streams tokens incrementally as they are generated. Automatically disabled if the selected endpoint type does not support streaming. Enables measurement of time-to-first-token (TTFT) and inter-token latency (ITL) metrics.
+<br/>_Flag (no value required)_
+
+#### `-u`, `--url` `<list>`
+
+Base URL(s) of the API server(s) to benchmark. Multiple URLs can be specified for load balancing across multiple instances (e.g., `--url http://server1:8000 --url http://server2:8000`). The endpoint path is automatically appended based on `--endpoint-type` (e.g., `/v1/chat/completions` for `chat`). URLs that do not include a scheme (no `://`) have `http://` prepended automatically.
+<br/>_Constraints: min: 1_
+<br/>_Default: `['http://localhost:8000']`_
+
+#### `--url-strategy` `<str>`
+
+Strategy for selecting URLs when multiple `--url` values are provided. 'round_robin' (default): distribute requests evenly across URLs in sequential order.
+<br/>_Choices: [`round_robin`]_
+<br/>_Default: `round_robin`_
+
+#### `--request-timeout-seconds` `<float>`
+
+Maximum time in seconds to wait for each HTTP request to complete, including connection establishment, request transmission, and response receipt. Applies to both streaming and non-streaming requests. Requests exceeding this timeout are cancelled and recorded as failures.
+<br/>_Constraints: > 0_
+<br/>_Default: `21600`_
+
+#### `--wait-for-model-timeout` `<float>`
+
+Seconds to wait for endpoint readiness before benchmarking (0 = skip). Sends a real inference request to verify the model is loaded and can generate output.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0.0`_
+
+#### `--wait-for-model-mode` `<str>`
+
+How readiness probes the endpoint: 'models' checks /v1/models, 'inference' sends a canned one-token inference request, and 'both' runs the models check before inference.
+<br/>_Default: `inference`_
+
+#### `--wait-for-model-interval` `<float>`
+
+Seconds between endpoint readiness probe attempts.
+<br/>_Constraints: > 0.0_
+<br/>_Default: `5.0`_
+
+#### `--reset-kv-cache`
+
+Enable once-per-cell KV-cache reset via POST to the endpoint.
+<br/>_Flag (no value required)_
+
+#### `--reset-kv-cache-timeout-seconds` `<float>`
+
+Timeout seconds for reset_kv_cache control requests.
+<br/>_Constraints: > 0_
+
+#### `--reset-kv-cache-path` `<str>`
+
+Relative path for reset_kv_cache (default /reset_prefix_cache).
+
+#### `--server-profiler`
+
+Enable server profiler start/stop around profiling phases.
+<br/>_Flag (no value required)_
+
+#### `--server-profiler-timeout-seconds` `<float>`
+
+Timeout seconds for server_profiler control requests.
+<br/>_Constraints: > 0_
+
+#### `--server-profiler-start-path` `<str>`
+
+Relative path for profiler start (default /start_profile).
+
+#### `--server-profiler-stop-path` `<str>`
+
+Relative path for profiler stop (default /stop_profile).
+
+#### `--api-key` `<str>`
+
+API authentication key for the endpoint. When provided, automatically included in request headers as `Authorization: Bearer <api_key>`.
+
+#### `--transport`, `--transport-type` `<str>`
+
+Transport protocol to use for API requests. If not specified, auto-detected from the URL scheme (`http`/`https` -> `TransportType.HTTP`). Currently supports `http` transport using aiohttp with connection pooling, TCP optimization, and Server-Sent Events (SSE) for streaming. Explicit override rarely needed.
+<br/>_Choices: [`http`]_
+
+#### `--use-legacy-max-tokens`
+
+Use the legacy 'max_tokens' field instead of 'max_completion_tokens' in request payloads. The OpenAI API now prefers 'max_completion_tokens', but some older APIs or implementations may require 'max_tokens'.
+<br/>_Flag (no value required)_
+
+#### `--use-server-token-count`
+
+Use server-reported token counts from API usage fields instead of client-side tokenization. When enabled, tokenizers are still loaded (needed for dataset generation) but tokenizer.encode() is not called for computing metrics. Token count fields will be None if the server does not provide usage information. For OpenAI-compatible streaming endpoints (chat/completions), stream_options.include_usage is automatically configured when this flag is enabled.
+<br/>_Flag (no value required)_
+
+#### `--per-chunk-usage`
+
+Request per-chunk token usage on streaming responses by setting stream_options.continuous_usage_stats, so the server reports cumulative usage on every chunk instead of only the final one. This lets inter-token latency subtract the first content chunk's real token count (fixing TPS/user inflation when a server bundles multiple tokens into the first streamed chunk). Requires a server that supports continuous_usage_stats (e.g. vLLM, TRT-LLM); strict OpenAI rejects it. Requires --use-server-token-count.
+<br/>_Flag (no value required)_
+
+#### `--connection-reuse-strategy` `<str>`
+
+Transport connection reuse strategy. 'pooled' (default): connections are pooled and reused across all requests. 'never': new connection for each request, closed after response. 'sticky-user-sessions': connection persists across turns of a multi-turn conversation, closed on final turn (enables sticky load balancing).
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `pooled` | _default_ | Connections are pooled and reused across all requests |
+| `never` |  | New connection for each request, closed after response |
+| `sticky-user-sessions` |  | Connection persists across turns of a multi-turn conversation, closed on final turn (enables sticky load balancing) |
+
+#### `--download-video-content`
+
+For video generation endpoints, download the video content after generation completes. When enabled, request latency includes the video download time. When disabled (default), only generation time is measured.
+<br/>_Flag (no value required)_
+
+#### `--request-content-type` `<str>`
+
+Content type for request body serialization. By default, requests are sent as 'application/json'. Set to 'multipart/form-data' for servers that require form-encoded requests (e.g., vLLM video generation endpoints).
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `application/json` |  | Standard JSON encoding. Default for all endpoints. |
+| `multipart/form-data` |  | Multipart form encoding. Required by some video generation servers (e.g., vLLM). |
+
+#### `--session-header` `<str>`
+
+HTTP header name used to carry the per-session affinity identifier. When set, replaces the default `X-Correlation-ID` header with the provided name (e.g., `--session-header X-Session-ID`).
+
+#### `--uuid-and-strip`
+
+Enable AIPerf-managed image stripping for vLLM's multimodal processor cache. Dataset-authored image UUIDs, including UUID-only cache references, always pass through on the chat endpoint; this flag only strips repeated content after AIPerf observes it in the same session. Automatic stripping supports only single_turn datasets with session_id-grouped rows; multi_turn is rejected. The server cache must cover the working set, and requests in a session must reach a replica that retains earlier UUIDs.
+<br/>_Flag (no value required)_
+
+### Tokenizer
+
+#### `--tokenizer` `<str>`
+
+HuggingFace tokenizer identifier, local path, or `builtin` for token counting in prompts and responses. Accepts model names (e.g., `meta-llama/Llama-2-7b-hf`), filesystem paths to tokenizer files, or `builtin` for a zero-network-access tokenizer backed by tiktoken (o200k_base encoding). If not specified, defaults to the value of `--model-names`. If `--tokenizer` is not set and the model name looks like an obvious placeholder (e.g. `mock-model`, `test-model`, `fake-model`), AIPerf substitutes `builtin` automatically and emits a warning. Essential for accurate token-based metrics (input/output token counts, token throughput).
+
+#### `--tokenizer-revision` `<str>`
+
+Specific tokenizer version to load from HuggingFace Hub. Can be a branch name (e.g., `main`), tag name (e.g., `v1.0`), or full commit hash. Ensures reproducible tokenization across runs by pinning to a specific version. Defaults to `main` branch if not specified.
+<br/>_Default: `main`_
+
+#### `--tokenizer-trust-remote-code`
+
+Allow execution of custom Python code from HuggingFace Hub tokenizer repositories. Required for tokenizers with custom implementations not in the standard `transformers` library. **Security Warning**: Only enable for trusted repositories, as this executes arbitrary code. Unnecessary for standard tokenizers.
+<br/>_Flag (no value required)_
+
+#### `--apply-chat-template`
+
+Apply the HuggingFace tokenizer's chat template when counting input tokens. When enabled: synthetic ISL is compensated for chat-template wrapping (BOS, role headers, EOT, generation-prompt suffix) and the record processor reports ISL using `apply_chat_template(tokenize=True, add_generation_prompt=True)` for chat-shape payloads. When disabled (default), both paths use bare-text encoding, so reported ISL matches the prompt content the user asked for and ignores template overhead. Requires an HF tokenizer with a chat template configured; no-ops on tiktoken / un-templated models.
+<br/>_Flag (no value required)_
+
+### Input
+
+#### `--extra-inputs` `<list>`
+
+Additional input parameters to include in every API request payload. Specify as `key:value` pairs (e.g., `--extra-inputs temperature:0.7 top_p:0.9`) or as JSON string (e.g., `'{"temperature": 0.7}'`). These parameters are merged with request-specific inputs and sent directly to the endpoint API.
+
+#### `-H`, `--header` `<list>`
+
+Custom HTTP headers to include with every request. Specify as `Header:Value` pairs (e.g., `--header X-Custom-Header:value`) or as JSON string. Can be specified multiple times. Useful for custom authentication, tracking, or API-specific requirements. Combined with auto-generated headers (e.g., `Authorization` from `--api-key`).
+
+#### `--input-file` `<str>`
+
+Path to file or directory containing benchmark dataset. Required when using `--custom-dataset-type`. Supported formats depend on dataset type: JSONL for `single_turn`/`multi_turn`, JSONL for `mooncake_trace`/`bailian_trace` (timestamped traces), Parquet for `baseten_trace`, directories for `random_pool`. File is parsed according to `--custom-dataset-type` specification.
+
+#### `--public-dataset` `<str>`
+
+Pre-configured public dataset to download and use for benchmarking (e.g., `sharegpt`). AIPerf automatically downloads and parses these datasets. Mutually exclusive with `--custom-dataset-type`. Run `aiperf plugins public_dataset_loader` to list available datasets. Use `--hf-subset` to override the HuggingFace subset/config for HF-backed datasets.
+<br/>_Choices: [`exgentic_v2`, `exgentic`, `sharegpt`, `aimo`, `mmstar`, `mmvu`, `vision_arena`, `llava_onevision`, `aimo_aime`, `aimo_numina_cot`, `aimo_numina_1_5`, `spec_bench`, `spec_al_gsm8k`, `spec_al_math500`, `spec_al_humaneval`, `spec_al_mbpp`, `spec_al_mtbench`, `instruct_coder`, `blazedit_5k`, `blazedit_10k`, `librispeech`, `voxpopuli`, `gigaspeech`, `ami`, `spgispeech`, `semianalysis_cc_traces_weka`, `semianalysis_cc_traces_weka_no_subagents`, `semianalysis_cc_traces_weka_with_subagents`, `semianalysis_cc_traces_weka_with_subagents_256k`, `semianalysis_cc_traces_weka_with_subagents_060226`, `semianalysis_cc_traces_weka_with_subagents_060226_256k`, `semianalysis_cc_traces_weka_with_subagents_060526`, `semianalysis_cc_traces_weka_with_subagents_060526_256k`, `semianalysis_cc_traces_weka_with_subagents_060826`, `semianalysis_cc_traces_weka_with_subagents_060826_256k`, `semianalysis_cc_traces_weka_061326`, `semianalysis_cc_traces_weka_061326_256k`, `semianalysis_cc_traces_weka_061526`, `semianalysis_cc_traces_weka_061526_256k`, `semianalysis_cc_traces_weka_062126`, `semianalysis_cc_traces_weka_062126_256k`, `weka_hf`]_
+
+#### `--hf-subset` `<str>`
+
+HuggingFace dataset subset/config name to override the plugin default (e.g. `sharegpt4o`). Only applies when using `--public-dataset` with a HuggingFace-backed loader. Takes priority over the subset defined in the plugin registry.
+
+#### `--hf-weka-dataset` `<str>`
+
+HuggingFace dataset repo for the generic Weka loader (e.g. `semianalysisai/cc-traces-weka-061526`). Passing this auto-selects `--public-dataset weka_hf`, so the repo flag works on its own; setting it alongside any other `--public-dataset` or `--custom-dataset-type` is an error. Pinned Weka public dataset aliases keep their registry-defined repo names.
+
+#### `--dataset-filter` `<list>`
+
+Dataset-specific filter in key=value form. Repeat for multiple filters. Only supported by public datasets that declare filter support.
+
+#### `--custom-dataset-type` `<str>`
+
+Format specification for custom dataset provided via `--input-file`. Determines parsing logic and expected file structure. Options: `single_turn` (JSONL with single exchanges), `multi_turn` (JSONL with conversation history), `tracelab` (TraceLab agentic-coding corpus, JSONL or gzipped JSONL), `mooncake_trace`/`bailian_trace`/`baseten_trace` (timestamped trace files), `random_pool` (directory of reusable prompts; when using `random_pool`, `--conversation-num` defaults to 100 if not specified; batch sizes > 1 sample each modality independently from a flat pool and do not preserve per-entry associations - use `single_turn` if paired modalities must stay together). Requires `--input-file`. Mutually exclusive with `--public-dataset`.
+<br/>_Choices: [`burst_gpt_trace`, `bailian_trace`, `baseten_trace`, `mooncake_trace`, `raw_payload`, `inputs_json`, `dag_jsonl`, `sagemaker_data_capture`, `multi_turn`, `random_pool`, `single_turn`, `speed_bench_qualitative`, `speed_bench_coding`, `speed_bench_humanities`, `speed_bench_math`, `speed_bench_multilingual`, `speed_bench_qa`, `speed_bench_rag`, `speed_bench_reasoning`, `speed_bench_roleplay`, `speed_bench_stem`, `speed_bench_summarization`, `speed_bench_writing`, `speed_bench_throughput_1k`, `speed_bench_throughput_2k`, `speed_bench_throughput_8k`, `speed_bench_throughput_16k`, `speed_bench_throughput_32k`, `speed_bench_throughput_1k_low_entropy`, `speed_bench_throughput_1k_mixed`, `speed_bench_throughput_1k_high_entropy`, `speed_bench_throughput_2k_low_entropy`, `speed_bench_throughput_2k_mixed`, `speed_bench_throughput_2k_high_entropy`, `speed_bench_throughput_8k_low_entropy`, `speed_bench_throughput_8k_mixed`, `speed_bench_throughput_8k_high_entropy`, `speed_bench_throughput_16k_low_entropy`, `speed_bench_throughput_16k_mixed`, `speed_bench_throughput_16k_high_entropy`, `speed_bench_throughput_32k_low_entropy`, `speed_bench_throughput_32k_mixed`, `speed_bench_throughput_32k_high_entropy`, `tracelab`, `weka_trace`]_
+
+#### `--ignore-trace-delays`
+
+Strip per-turn timestamps and inter-turn delays from trace datasets at load time. With this flag, Turn.timestamp and Turn.delay are emitted as None so concurrency / request-rate timing modes dispatch turns back-to-back instead of reproducing the recorded user think-time gaps. No effect under `--fixed-schedule` (timestamps drive that mode before they could be ignored -- combine with `--no-fixed-schedule` if you want both behaviors).
+<br/>_Flag (no value required)_
+
+#### `--use-think-time-only`
+
+For weka_trace inputs, emit Turn.delay using only the recorded per-request `think_time` (client-side delay before each request) instead of the full `t_curr - t_prev` inter-request delta. Compresses replay wall time against zero-latency mocks because the recorded `api_time` portion of each gap is dropped. Mirrors kv-cache-tester's default `--timing-strategy think-only`. Falls back to the full delta for turns whose recorded `think_time` is null. Mutually exclusive with `--ignore-trace-delays`. No effect on non-weka trace loaders.
+<br/>_Flag (no value required)_
+
+#### `--max-context-length` `<int>`
+
+Maximum peak prompt+output context length (tokens) per Weka root trace. Weka loaders (--custom-dataset-type weka_trace or a weka --public-dataset) drop whole traces whose *recorded* peak exceeds this ceiling at load time (filter-then-cap before --num-dataset-entries). Not a DatasetManager tokenize filter; rejected for non-Weka formats.
+<br/>_Constraints: ≥ 1_
+
+#### `--dataset-sampling-strategy` `<str>`
+
+Strategy for selecting entries from dataset during benchmarking. `sequential`: Iterate through dataset in order, wrapping to start after end. `random`: Randomly sample with replacement (entries may repeat before all are used). `shuffle`: Shuffle dataset and iterate without replacement, re-shuffling after exhaustion. Default behavior depends on dataset type (e.g., `sequential` for traces, `shuffle` for synthetic).
+<br/>_Choices: [`random`, `sequential`, `shuffle`]_
+
+#### `--allow-dataset-wrap`, `--no-allow-dataset-wrap`
+
+Allow weka/agentic replay to wrap (reuse distinct eligible traces across concurrency lanes) when concurrency exceeds the loaded pool. Defaults to False: over-subscription fails unless wrapping is explicitly enabled or an active --cache-bust target already keeps repeated-trace traffic distinct.
+
+#### `--random-seed` `<int>`
+
+Random seed for deterministic data generation. When set, makes synthetic prompts, sampling, delays, and other random operations reproducible across runs. Essential for A/B testing and debugging. Uses system entropy if not specified. Initialized globally at config creation.
+<br/>_Constraints: ≥ 0_
+
+#### `--trace-session-sample-ratio` `<float>`
+
+Fraction of trace sessions to keep for replay, sampled whole-session to preserve multi-turn integrity; deterministic when `--random-seed` is set. Only supported by the baseten_trace loader.
+<br/>_Constraints: > 0.0, ≤ 1.0_
+
+#### `-f`, `--config` `<str>`
+
+Path to a YAML configuration file. CLI flags override values from the config file. A flag that cannot be applied on top of a config file is rejected by name rather than ignored, so a run never silently differs from what was asked for.
+
+### Fixed Schedule
+
+#### `--fixed-schedule`
+
+Run requests according to timestamps specified in the input dataset. When enabled, AIPerf replays the exact timing pattern from the dataset. This mode is automatically enabled for trace datasets.
+<br/>_Flag (no value required)_
+
+#### `--no-fixed-schedule`
+
+Suppress the automatic switch to fixed-schedule mode for trace datasets that carry per-record timestamps. By default a trace input (e.g. mooncake_trace) with timestamps in the first record auto-promotes the profiling phase to fixed_schedule. Pass --no-fixed-schedule to keep the user-selected timing mode (e.g. concurrency, request_rate) and ignore the trace timestamps.
+
+#### `--fixed-schedule-auto-offset`
+
+Automatically normalize timestamps in fixed schedule by shifting all timestamps so the first timestamp becomes 0. When enabled, benchmark starts immediately with the timing pattern preserved. When disabled, timestamps are used as absolute offsets from benchmark start. Mutually exclusive with `--fixed-schedule-start-offset`.
+<br/>_Flag (no value required)_
+
+#### `--fixed-schedule-start-offset` `<int>`
+
+Start offset in milliseconds for fixed schedule replay. Skips all requests before this timestamp, allowing benchmark to start from a specific point in the trace. Requests at exactly the start offset are included. Useful for analyzing specific time windows. Mutually exclusive with `--fixed-schedule-auto-offset`. Must be ≤ `--fixed-schedule-end-offset` if both specified.
+<br/>_Constraints: ≥ 0_
+
+#### `--fixed-schedule-end-offset` `<int>`
+
+End offset in milliseconds for fixed schedule replay. Stops issuing requests after this timestamp, allowing benchmark of specific trace subsets. Requests at exactly the end offset are included. Defaults to last timestamp in dataset. Must be ≥ `--fixed-schedule-start-offset` if both specified.
+<br/>_Constraints: ≥ 0_
+
+### Goodput
+
+#### `--goodput` `<str>`
+
+Specify service level objectives (SLOs) for goodput as space-separated 'KEY:VALUE' pairs, where KEY is a metric tag and VALUE is a number in the metric's display unit (falls back to its base unit if no display unit is defined). Examples: 'request_latency:250' (ms), 'inter_token_latency:10' (ms), `output_token_throughput_per_user:600` (tokens/s). Only metrics applicable to the current endpoint/config are considered. For more context on the definition of goodput, refer to DistServe paper: https://arxiv.org/pdf/2401.09670 and the blog: https://hao-ai-lab.github.io/blogs/distserve.
+
+### Conversation Input
+
+#### `--conversation-num`, `--num-conversations`, `--num-sessions` `<str>`
+
+The total number of unique conversations to generate. Each conversation represents a single request session between client and server. Supported on synthetic mode and the custom random_pool dataset. The number of conversations will be used to determine the number of entries in both the custom random_pool and synthetic datasets and will be reused until benchmarking is complete. Pass a comma-separated list (e.g. `--num-conversations 50,100,200`) to sweep over session-bounded run lengths; the converter promotes the list to a sweep on phases.profiling.sessions before AIPerfConfig validation. The synthetic dataset pool is sized to max(list) so every variation has its full unique-session set.
+
+#### `--num-dataset-entries`, `--num-prompts` `<int>`
+
+Total number of unique entries to generate for the dataset. Each entry represents one user message that can be used as a turn in conversations. Entries are reused across conversations and turns according to `--dataset-sampling-strategy`. Higher values provide more diversity.
+<br/>_Constraints: ≥ 1_
+<br/>_Default: `100`_
+
+#### `--conversation-turn-mean`, `--session-turns-mean` `<int>`
+
+Mean number of request-response turns per conversation. Each turn consists of a user message and model response. Turn counts follow normal distribution around this mean (±`--conversation-turn-stddev`). Set to 1 for single-turn interactions. Multi-turn conversations enable testing of context retention and conversation history handling. Pass a comma-separated list (e.g. `--conversation-turn-mean 1,3,8`) to sweep over multiple turn-mean values; the converter promotes the list to a sweep on datasets.main.turns.mean before AIPerfConfig validation.
+<br/>_Default: `1`_
+
+#### `--conversation-turn-stddev`, `--session-turns-stddev` `<int>`
+
+Standard deviation for number of turns per conversation. Creates variability in conversation lengths, simulating diverse interaction patterns (quick questions vs. extended dialogues). Turn counts follow normal distribution. Set to 0 for uniform conversation lengths.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0`_
+
+#### `--conversation-turn-delay-mean`, `--session-turn-delay-mean` `<float>`
+
+Mean delay in milliseconds between consecutive turns within a multi-turn conversation. Simulates user think time between receiving a response and sending the next message. Delays follow normal distribution around this mean (±`--conversation-turn-delay-stddev`). Only applies to multi-turn conversations (`--conversation-turn-mean` > 1). Set to 0 for back-to-back turns.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0.0`_
+
+#### `--conversation-turn-delay-stddev`, `--session-turn-delay-stddev` `<float>`
+
+Standard deviation for turn delays in milliseconds. Creates variability in user think time between conversation turns. Delays follow normal distribution. Set to 0 for deterministic delays. Models realistic human interaction patterns with variable response times.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0.0`_
+
+#### `--conversation-turn-delay-ratio`, `--session-delay-ratio` `<float>`
+
+Multiplier for scaling all turn delays within conversations. Applied after mean/stddev calculation: `actual_delay = calculated_delay × ratio`. Use to proportionally adjust timing without changing distribution shape. Values &lt; 1 speed up conversations, > 1 slow them down. Set to 0 to eliminate delays entirely.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `1.0`_
+
+#### `--inter-turn-delay-cap-seconds` `<float>`
+
+Clamp per-turn replay delays to at most this many seconds; ``None`` disables the cap. Honored by the DAG JSONL loader and the baseten_trace loader's closed-loop think-times; the clamp count is reported at end of load. Maps to FileDataset ``inter_turn_delay_cap_seconds``.
+<br/>_Constraints: ≥ 0.0_
+
+#### `--max-idle-gap-cap-seconds` `<float>`
+
+Collapse idle gaps between consecutive requests (across all sessions) to at most this many seconds, so a sparse or session-sampled trace does not replay dead air; ``None`` disables the cap. The cap is in replay wall-clock seconds, applied after --replay-speedup compression, so it bounds actual benchmark idle time regardless of speedup. Only supported by the baseten_trace loader. Maps to FileDataset ``max_idle_gap_cap_seconds``.
+<br/>_Constraints: > 0.0_
+
+#### `--replay-speedup` `<float>`
+
+Trace replay wall-clock compression (10 = 10x faster than recorded): divides normalized timestamps and inter-turn delays; ``None`` = real time. Unlike synthesis speedup_ratio, hash_ids stay untouched (KV-cache fidelity). Only supported by the baseten_trace loader. Maps to FileDataset ``replay_speedup``.
+<br/>_Constraints: > 0.0_
+
+#### `--open-loop-replay`, `--no-open-loop-replay`
+
+Open-loop replay (the default): each session starts at its absolute, speedup-scaled recorded timestamp; continuation turns fire at max(recorded timestamp, prior-turn completion). Pass `--no-open-loop-replay` for closed-loop back-pressure: continuation turns fire a think-time (recorded start-to-start gap minus recorded e2e duration) after the prior turn completes, keeping sessions causally ordered when replayed service times differ from recorded (e.g. A/A comparisons). Only honored by the baseten_trace loader. Maps to FileDataset ``open_loop_replay``.
+<br/>_Default: `True`_
+
+#### `--open-loop-strict`
+
+In open-loop replay, fire every trace row at its absolute recorded timestamp as an independent single-turn session, trading away multi-turn grouping and session metrics. Only honored by the baseten_trace loader. Maps to FileDataset ``open_loop_strict``.
+<br/>_Flag (no value required)_
+
+#### `--omit-kv-hints`
+
+Drop recorded KV-cache hints (``hash_ids``, ``block_size``) from replayed request bodies, for strict frontends that reject unknown parameters. Only honored by the baseten_trace loader. Maps to FileDataset ``omit_kv_hints``.
+<br/>_Flag (no value required)_
+
+#### `--force-min-tokens`, `--no-force-min-tokens`
+
+Pin ``min_tokens`` to the recorded output length so replayed generations match recorded lengths; pass `--no-force-min-tokens` to let EOS end generations naturally (some servers reject ``min_tokens``). Only honored by the baseten_trace loader. Maps to FileDataset ``force_min_tokens``.
+<br/>_Default: `True`_
+
+### Prompt
+
+#### `-b`, `--prompt-batch-size`, `--batch-size-text`, `--batch-size` `<int>`
+
+Number of text inputs to include in each request for batch processing endpoints. Supported by `embeddings` and `rankings` endpoint types where models can process multiple inputs simultaneously for efficiency. Set to 1 for single-input requests. Not applicable to `chat` or `completions` endpoints.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `1`_
+
+#### `--prompt-corpus` `<str>`
+
+Source corpus for synthetic prompt text generation. 'sonnet' uses Shakespeare sonnets. 'coding' uses realistic coding content (code, bash output, JSON, error tracebacks, git diffs). Honored only for synthesized content (synthetic datasets and count/hash-id trace loaders); verbatim formats ignore it. When unset, the active dataset loader's default applies (most loaders default to 'sonnet'; agentic-coding loaders such as weka_trace default to 'coding').
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `sonnet` |  | Shakespeare sonnets (default). Classic prose for filler text. |
+| `coding` |  | Realistic coding content: code, bash output, JSON, error tracebacks, git diffs. |
+| `random` |  | Random tokens drawn from the full tokenizer vocabulary minus special tokens. Matches vLLM bench's RandomDataset token-generation strategy. |
+
+### Cache Bust
+
+#### `--cache-bust` `<str>`
+
+Where (and how) to inject a cache-bust marker. Two families: (1) RID targets (system_prefix, system_suffix, first_turn_prefix, first_turn_suffix) — inject a per-trajectory unique SHA-256 digest marker that is identical across warmup and profiling, so warmup KV-cache work transfers to profiling while preventing cross-trajectory cache sharing. Prefix variants prepend at token 0; suffix variants append after existing content. (2) Warmup-isolation targets (warmup_isolation_system, warmup_isolation_first_turn) — inject a constant '[warmup]' marker only during the WARMUP phase; profiling sees no marker (fully cold start or system-pre-warmed). Incompatible with agentic_replay timing mode. 'none' disables the feature (default). See [cache-bust.md](reference/cache-bust.md) for detailed semantics, trade-offs, and examples.
+<br/>_Choices: [`none`, `system_prefix`, `system_suffix`, `first_turn_prefix`, `first_turn_suffix`, `warmup_isolation_system`, `warmup_isolation_first_turn`]_
+<br/>_Default: `none`_
+
+### Prefix Prompt
+
+#### `--system-prompt` `<str>`
+
+Verbatim system prompt text, identical across every conversation. Sent as a system-role message ahead of all turns. Works with both synthetic and file/public datasets; when the dataset already carries its own system message, this text is prepended to it. Tokens are additive: `--isl` continues to size the generated user prompt only. Mutually exclusive with `--system-prompt-file`, `--shared-system-prompt-length`, and `--num-prefix-prompts`/`--prefix-prompt-length`.
+
+#### `--system-prompt-file` `<str>`
+
+Path to a UTF-8 text file holding the verbatim system prompt. Preferred over `--system-prompt` for real production prompts, which are long enough that shell quoting mangles them. Read once at startup, so a missing or unreadable file fails immediately rather than mid-run. Mutually exclusive with `--system-prompt`, `--shared-system-prompt-length`, and `--num-prefix-prompts`/`--prefix-prompt-length`.
+
+#### `--prompt-prefix-pool-size`, `--prefix-prompt-pool-size`, `--num-prefix-prompts` `<int>`
+
+Number of distinct prefix prompts to generate for K-V cache testing. Each prefix is prepended to user prompts, simulating cached context scenarios. Prefixes randomly selected from pool per request. Set to 0 to disable prefix prompts. Mutually exclusive with `--shared-system-prompt-length`/`--user-context-prompt-length`.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0`_
+
+#### `--prompt-prefix-length`, `--prefix-prompt-length` `<int>`
+
+The number of tokens in each prefix prompt. This is only used if `--num-prefix-prompts` is greater than zero. Note that due to the prefix and user prompts being concatenated, the number of tokens in the final prompt may be off by one.Mutually exclusive with `--shared-system-prompt-length`/`--user-context-prompt-length`.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0`_
+
+#### `--shared-system-prompt-length` `<int>`
+
+Length of shared system prompt in tokens. This prompt is identical across all sessions and appears as a system message. Mutually exclusive with `--prefix-prompt-length`/`--prefix-prompt-pool-size`.
+<br/>_Constraints: ≥ 1_
+
+#### `--user-context-prompt-length` `<int>`
+
+Length of per-session user context prompt in tokens. Each dataset entry gets a unique user context prompt. Requires --num-dataset-entries to be specified. Mutually exclusive with --prefix-prompt-length/--prefix-prompt-pool-size.
+<br/>_Constraints: ≥ 1_
+
+### Input Sequence Length (ISL)
+
+#### `--prompt-input-tokens-mean`, `--synthetic-input-tokens-mean`, `--isl` `<int>`
+
+Mean number of tokens for synthetically generated input prompts. AIPerf generates prompts with lengths following a normal distribution around this mean (±`--prompt-input-tokens-stddev`). Applies only to synthetic datasets, not custom or public datasets. Pass a comma-separated list (e.g. `--isl 128,512,2048`) to sweep over multiple input lengths; the converter promotes the list to a sweep on datasets.main.prompts.isl.mean before AIPerfConfig validation.
+<br/>_Default: `550`_
+
+#### `--prompt-input-tokens-stddev`, `--synthetic-input-tokens-stddev`, `--isl-stddev` `<float>`
+
+Standard deviation for synthetic input prompt token lengths. Creates variability in prompt sizes when > 0, simulating realistic workloads with mixed request sizes. Lengths follow normal distribution. Set to 0 for uniform prompt lengths. Applies only to synthetic data generation. Pass a comma-separated list (e.g. `--isl-stddev 10,50,200`) to sweep over multiple stddev values; the converter promotes the list to a sweep on datasets.main.prompts.isl.stddev. Pair with a zip-mode `--isl` sweep to model realistic small/medium/large traffic shapes.
+<br/>_Default: `0.0`_
+
+#### `--prompt-input-tokens-block-size`, `--synthetic-input-tokens-block-size`, `--isl-block-size` `<int>`
+
+Token block size for hash-based prompt synthesis when dataset entries carry `hash_ids`: each `hash_id` maps to a cached block of `block_size` tokens, enabling simulation of KV-cache sharing patterns from production workloads. The total prompt length equals `(num_hash_ids - 1) * block_size + final_block_size`. With `--input-file` this overrides the trace loader's `default_block_size` plugin metadata (16 for `bailian_trace`, 512 for `mooncake_trace`) for loaders that reconstruct prompts from `hash_ids`; it has no effect on `baseten_trace`, which replays literal recorded prompts. Set it when a trace was recorded at a block size different from its loader default (e.g. a Mooncake-format trace recorded at 16).
+<br/>_Constraints: ≥ 1_
+
+#### `--seq-dist`, `--sequence-distribution` `<str>`
+
+Distribution of (ISL, OSL) pairs with probabilities for mixed workload simulation. Format: `ISL,OSL:prob;ISL,OSL:prob` (semicolons separate pairs, probabilities are percentages 0-100 that must sum to 100). Supports optional stddev: `ISL|stddev,OSL|stddev:prob`. Examples: `128,64:25;512,128:50;1024,256:25` or with variance: `256|10,128|5:40;512|20,256|10:60`. Also supports bracket `[(256,128):40,(512,256):60]` and JSON formats.
+
+#### `--random-range-ratio` `<str>`
+
+Sample ISL and OSL uniformly from a ratio-defined integer window around the configured means. The window is computed from `--random-corpus-style` (defaults to `vllm`): vllm style → `[floor(mean*(1-r)), ceil(mean*(1+r))]` (symmetric); sglang style → `[max(1, int(mean*r)), mean]` (lower-bounded). Accepts a single float applied to both ISL and OSL. The JSON object form `{"input": 0.3, "output": 0.5}` for independent values is accepted only under vllm style; sglang style applies one ratio to both and requires a plain float. Requires both `--isl` and `--osl` to be set explicitly — there is no default mean for either. Mutually exclusive with `--seq-dist`. Under vllm style with a tokenizer configured, the ISL mean is automatically reduced by `tokenizer.num_special_tokens_to_add(pair=False)` so `--isl` represents total server-side input tokens, matching `vllm bench serve` semantics; sglang style applies no such adjustment.
+
+#### `--random-corpus-style` `<str>`
+
+Benchmark style for RANDOM corpus generation. Controls range ratio formula, token pool composition, and other per-tool behaviors. `vllm` (default) mirrors `vllm bench serve`: symmetric range window, non-special token pool (special tokens excluded). `sglang` mirrors `sglang.benchmark.serving` run with `--dataset-name random-ids`: lower-bounded range window, full `range(vocab_size)` token pool (no exclusion). Applies in two independent places: token-pool selection whenever `--prompt-corpus random` is set (including with no `--random-range-ratio`, where the pool is the only thing the style selects), and the range-window formula, special-token accounting and RNG algorithm whenever `--random-range-ratio` is set — the latter regardless of corpus.
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `vllm` | _default_ | vllm bench serve semantics: symmetric window ``[floor(mean*(1-r)), ceil(mean*(1+r))]``. r=0 is fixed at mean; larger r widens the window on both sides. r must be in [0, 1). Special tokens excluded from the sampling pool. BOS subtracted from ISL mean. |
+| `sglang` |  | sglang ``benchmark.serving`` semantics under ``--dataset-name random-ids``: lower-bounded window ``[max(1, int(mean*r)), mean]``. r=0 allows full variability [1, mean]; r=1 fixes length at mean. Full vocab_size range used for token sampling (no special-token exclusion). No BOS adjustment. The default ``--dataset-name random`` is a different algorithm upstream (repeat/truncate ShareGPT token ids) and is not what this style mirrors. |
+
+### Output Sequence Length (OSL)
+
+#### `--prompt-output-tokens-mean`, `--output-tokens-mean`, `--osl` `<str>`
+
+Mean number of tokens to request in model outputs via `max_completion_tokens` field. Controls response length for synthetic and some custom datasets. If specified, included in request payload to limit generation length. When not set, model determines output length. Pass a comma-separated list (e.g. `--osl 128,256,512`) to sweep over multiple output lengths; the converter promotes the list to a sweep on datasets.main.prompts.osl.mean before AIPerfConfig validation.
+
+#### `--prompt-output-tokens-stddev`, `--output-tokens-stddev`, `--osl-stddev` `<int>`
+
+Standard deviation for output token length requests. Creates variability in `max_completion_tokens` field across requests, simulating mixed response length requirements. Lengths follow normal distribution. Only applies when `--prompt-output-tokens-mean` is set. Pass a comma-separated list (e.g. `--osl-stddev 5,25,100`) to sweep over multiple stddev values; the converter promotes the list to a sweep on datasets.main.prompts.osl.stddev. Pair with a zip-mode `--osl` sweep to model realistic output-length variance across traffic tiers.
+<br/>_Default: `0`_
+
+### Audio Input
+
+#### `--audio-batch-size`, `--batch-size-audio` `<int>`
+
+The number of audio inputs to include in each request. Supported with the `chat` endpoint type for multimodal models.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `1`_
+
+#### `--audio-length-mean` `<float>`
+
+Mean duration in seconds for synthetically generated audio files. Audio lengths follow a normal distribution around this mean (±`--audio-length-stddev`). Used when `--audio-batch-size` > 0 for multimodal benchmarking. Generated audio is random noise with specified sample rate, bit depth, and format.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0.0`_
+
+#### `--audio-length-stddev` `<float>`
+
+Standard deviation for synthetic audio duration in seconds. Creates variability in audio lengths when > 0, simulating mixed-duration audio inputs. Durations follow normal distribution. Set to 0 for uniform audio lengths.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0.0`_
+
+#### `--audio-format` `<str>`
+
+File format for generated audio files. Supports `wav` (uncompressed PCM, larger files) and `mp3` (compressed, smaller files). Format choice affects file size in multimodal requests but not audio characteristics (sample rate, bit depth, duration).
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `wav` | _default_ | WAV format. Uncompressed audio, larger file sizes, best quality. |
+| `mp3` |  | MP3 format. Compressed audio, smaller file sizes, good quality. |
+
+#### `--audio-depths` `<list>`
+
+List of audio bit depths in bits to randomly select from when generating audio files. Each audio file is assigned a random depth from this list. Common values: `8` (low quality), `16` (CD quality), `24` (professional), `32` (high-end). Specify multiple values (e.g., `--audio-depths 16 24`) for mixed-quality testing.
+<br/>_Constraints: min: 1_
+<br/>_Default: `[16]`_
+
+#### `--audio-sample-rates` `<list>`
+
+A list of audio sample rates to randomly select from in kHz. Common sample rates are 16, 44.1, 48, 96, etc.
+<br/>_Constraints: min: 1_
+<br/>_Default: `[16.0]`_
+
+#### `--audio-num-channels` `<int>`
+
+Number of audio channels for synthetic audio generation. `1` = mono (single channel), `2` = stereo (left/right channels). Stereo doubles file size but simulates realistic audio for models supporting spatial audio processing. Most speech models use mono.
+<br/>_Constraints: ≥ 1, ≤ 2_
+<br/>_Default: `1`_
+
+### Image Input
+
+#### `--image-width-mean` `<float>`
+
+Mean width in pixels for synthetically generated images. Image widths follow a normal distribution around this mean (±`--image-width-stddev`). Combined with `--image-height-mean` to determine image dimensions and file sizes for multimodal benchmarking.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0.0`_
+
+#### `--image-width-stddev` `<float>`
+
+Standard deviation for synthetic image widths in pixels. Creates variability in horizontal resolution when > 0, simulating mixed-resolution image inputs. Widths follow normal distribution. Set to 0 for uniform image widths.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0.0`_
+
+#### `--image-height-mean` `<float>`
+
+Mean height in pixels for synthetically generated images. Image heights follow a normal distribution around this mean (±`--image-height-stddev`). Used when `--image-batch-size` > 0 for multimodal vision benchmarking. Generated images are resized from source images in `assets/source_images` directory.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0.0`_
+
+#### `--image-height-stddev` `<float>`
+
+Standard deviation for synthetic image heights in pixels. Creates variability in vertical resolution when > 0, simulating mixed-resolution image inputs. Heights follow normal distribution. Set to 0 for uniform image heights.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0.0`_
+
+#### `--image-batch-size`, `--batch-size-image` `<int>`
+
+Number of images to include in each multimodal request. Supported with `chat` endpoint type for vision-language models. Each image is generated by randomly sampling and resizing source images from `assets/source_images` directory to specified dimensions. Set to 0 to disable image inputs. Higher batch sizes test multi-image understanding and increase request payload size.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `1`_
+
+#### `--image-format` `<str>`
+
+Image file format for generated images. Choose `png` for lossless compression (larger files, best quality), `jpeg` for lossy compression (smaller files, good quality), or `random` to randomly select between PNG and JPEG for each image. Format affects file size in multimodal requests and encoding overhead.
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `png` | _default_ | PNG format. Lossless compression, larger file sizes, best quality. |
+| `jpeg` |  | JPEG format. Lossy compression, smaller file sizes, good for photos. |
+| `random` |  | Randomly select PNG or JPEG for each image. |
+
+#### `--image-source` `<str>`
+
+Source image generation mode (default `noise`). `noise` generates random noise images on the fly at the requested dimensions — no files on disk required, and the pool is effectively unbounded so servers cannot dedupe on identical inputs. `assets` indexes images from the built-in `assets/source_images` directory (ships with a small set of 4 images) and lazily loads them at the requested dimensions. A path to a directory indexes images from the given directory (e.g. `--image-source ./source_images`). Note: random-noise images are roughly incompressible, so payload bytes are larger than equivalent natural images.
+<br/>_Default: `noise`_
+
+#### `--image-source-sampling` `<str>`
+
+How source images are selected from finite image sources selected by `--image-source assets` or `--image-source <directory>`. `random-with-replacement` draws each source image independently; repeats may occur immediately. `shuffle-cycle` draws every source image once per shuffled cycle, reshuffling after exhaustion. `sequential-cycle` walks source images in sorted load order and wraps after exhaustion. For `noise`, only `random-with-replacement` is valid because there is no finite source pool.
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `random-with-replacement` | _default_ | Draw each source image independently; repeats may occur immediately. |
+| `shuffle-cycle` |  | Draw every source image once per shuffled cycle; reshuffle after exhaustion. |
+| `sequential-cycle` |  | Walk source images in sorted load order; wrap after exhaustion. |
+
+### Video Input
+
+#### `--video-batch-size`, `--batch-size-video` `<int>`
+
+Number of video files to include in each multimodal request. Supported with `chat` endpoint type for video understanding models. Each video is generated synthetically with specified duration, FPS, resolution, and codec. Set to 0 to disable video inputs. Higher batch sizes test multi-video understanding and significantly increase request payload size.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `1`_
+
+#### `--video-duration` `<float>`
+
+Duration in seconds for each synthetically generated video clip. Combined with `--video-fps`, determines total frame count (frames = duration × FPS). Longer durations increase file size and processing time. Typical values: 1-10 seconds for testing. Requires FFmpeg for video generation.
+<br/>_Constraints: ≥ 0.0_
+<br/>_Default: `5.0`_
+
+#### `--video-fps` `<int>`
+
+Frames per second for generated video. Higher FPS creates smoother video but increases frame count and file size. Common values: `4` (minimal motion, recommended for Cosmos models), `24` (cinematic), `30` (standard video), `60` (high frame rate). Total frames = `--video-duration` × FPS.
+<br/>_Constraints: ≥ 1_
+<br/>_Default: `4`_
+
+#### `--video-width` `<int>`
+
+Video frame width in pixels. Must be specified together with `--video-height` (both or neither). Determines video resolution and file size. Common resolutions: `640×480` (SD), `1280×720` (HD), `1920×1080` (Full HD). If not specified, uses codec/format defaults.
+<br/>_Constraints: ≥ 1_
+
+#### `--video-height` `<int>`
+
+Video frame height in pixels. Must be specified together with `--video-width` (both or neither). Combined with width determines aspect ratio and total pixel count per frame. Higher resolution increases processing demands and file size.
+<br/>_Constraints: ≥ 1_
+
+#### `--video-synth-type` `<str>`
+
+Algorithm for generating synthetic video content. Different types produce different visual patterns for testing. Options: `moving_shapes` (animated geometric shapes), `grid_clock` (grid with rotating clock hands), `noise` (random pixel frames). Content doesn't affect semantic meaning but may impact encoding efficiency and file size.
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `moving_shapes` | _default_ | Generate videos with animated geometric shapes moving across the frame |
+| `grid_clock` |  | Generate videos with a grid pattern and frame number overlay for frame-accurate verification |
+| `noise` |  | Generate videos with random noise frames |
+
+#### `--video-format` `<str>`
+
+Container format for generated video files. Supports `webm` (VP9, recommended, BSD-licensed) and `mp4` (widely compatible container, VP9 by default). Format choice affects compatibility, file size, and encoding options. `mp4` is the more portable container, but note that the default VP9 video and Opus audio are less widely supported by players than H.264/AAC would be.
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `mp4` |  | MP4 container. Widely compatible, good for H.264/H.265 codecs. |
+| `webm` | _default_ | WebM container. Open format, optimized for web, good for VP9 codec. |
+
+#### `--video-codec` `<str>`
+
+The video codec to use for encoding. Common options: libvpx-vp9 (CPU, BSD-licensed, default), libvpx (CPU, BSD-licensed, VP8). Any codec the local FFmpeg supports can be used, but the AIPerf container ships a minimal FFmpeg build limited to VP8/VP9 video with Vorbis/Opus audio; codecs such as libx264 or h264_nvenc require an FFmpeg build that includes them.
+<br/>_Default: `libvpx-vp9`_
+
+#### `--video-audio-sample-rate` `<float>`
+
+Audio sample rate in Hz or kHz for the embedded audio track. Common values: 8/8000 (telephony), 16/16000 (speech), 44.1/44100 (CD quality), 48/48000 (professional). Higher sample rates increase audio fidelity and file size.
+<br/>_Constraints: ≥ 8, ≤ 96000_
+<br/>_Default: `44100`_
+
+#### `--video-audio-num-channels` `<int>`
+
+Number of audio channels to embed in generated video files. 0 = disabled (no audio track, default), 1 = mono, 2 = stereo. When set to 1 or 2, a Gaussian noise audio track matching the video duration is muxed into each video via FFmpeg.
+<br/>_Constraints: ≥ 0, ≤ 2_
+<br/>_Default: `0`_
+
+#### `--video-audio-codec` `<str>`
+
+Audio codec for the embedded audio track. If not specified, auto-selects based on video format: libopus for MP4, libvorbis for WebM. Options: libvorbis, libopus, aac. The AIPerf container ships only libvorbis and libopus; aac requires an FFmpeg build that includes an AAC encoder. libopus always encodes at 48 kHz, so any --video-audio-sample-rate is resampled during muxing.
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `aac` |  | AAC codec. Not built into the AIPerf container's FFmpeg; selecting it requires an FFmpeg build that includes an AAC encoder. |
+| `libvorbis` |  | Vorbis codec. Default for WebM containers. |
+| `libopus` |  | Opus codec. Default for MP4 containers. Always encodes at 48 kHz regardless of the requested sample rate. |
+
+#### `--video-audio-depth` `<str>`
+
+Audio bit depth for the embedded audio track. Supported values: 8, 16, 24, or 32 bits. Higher bit depths provide greater dynamic range but increase file size.
+<br/>_Default: `16`_
+
+### Rankings
+
+#### `--rankings-passages-mean` `<int>`
+
+Mean number of passages to include per ranking request. For `rankings` endpoint type, each request contains a query and multiple passages to rank. Passages follow normal distribution around this mean (±`--rankings-passages-stddev`). Higher values test ranking at scale but increase request payload size and processing time.
+<br/>_Constraints: ≥ 1_
+<br/>_Default: `1`_
+
+#### `--rankings-passages-stddev` `<int>`
+
+Standard deviation for number of passages per ranking request. Creates variability in ranking workload complexity. Passage counts follow normal distribution. Set to 0 for uniform passage counts across all requests.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0`_
+
+#### `--rankings-passages-prompt-token-mean` `<int>`
+
+Mean token length for each passage in ranking requests. Passages are synthetically generated text with lengths following normal distribution around this mean (±`--rankings-passages-prompt-token-stddev`). Longer passages increase input processing demands and request size.
+<br/>_Constraints: ≥ 1_
+<br/>_Default: `550`_
+
+#### `--rankings-passages-prompt-token-stddev` `<int>`
+
+Standard deviation for passage token lengths in ranking requests. Creates variability in passage sizes, simulating realistic heterogeneous document collections. Token lengths follow normal distribution. Set to 0 for uniform passage lengths.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0`_
+
+#### `--rankings-query-prompt-token-mean` `<int>`
+
+Mean token length for query text in ranking requests. Each ranking request contains one query and multiple passages. Queries are synthetically generated with lengths following normal distribution around this mean (±`--rankings-query-prompt-token-stddev`).
+<br/>_Constraints: ≥ 1_
+<br/>_Default: `550`_
+
+#### `--rankings-query-prompt-token-stddev` `<int>`
+
+Standard deviation for query token lengths in ranking requests. Creates variability in query complexity, simulating realistic user search patterns. Token lengths follow normal distribution. Set to 0 for uniform query lengths.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0`_
+
+### Synthesis
+
+#### `--synthesis-speedup-ratio` `<float>`
+
+Multiplier for timestamp scaling in synthesized traces.
+<br/>_Constraints: ≥ 0.0_
+<br/>_Default: `1.0`_
+
+#### `--synthesis-prefix-len-multiplier` `<float>`
+
+Multiplier for core prefix branch lengths in radix tree.
+<br/>_Constraints: ≥ 0.0_
+<br/>_Default: `1.0`_
+
+#### `--synthesis-prefix-root-multiplier` `<int>`
+
+Number of independent radix trees to distribute traces across.
+<br/>_Constraints: ≥ 1_
+<br/>_Default: `1`_
+
+#### `--synthesis-prompt-len-multiplier` `<float>`
+
+Multiplier for leaf path (unique prompt) lengths.
+<br/>_Constraints: ≥ 0.0_
+<br/>_Default: `1.0`_
+
+#### `--synthesis-output-len-multiplier` `<float>`
+
+Multiplier for output lengths in synthesized traces.
+<br/>_Constraints: ≥ 0.0_
+<br/>_Default: `1.0`_
+
+#### `--synthesis-max-isl` `<int>`
+
+Maximum input sequence length for filtering. Traces with input_length > max_isl are skipped.
+<br/>_Constraints: ≥ 1_
+
+#### `--synthesis-max-osl` `<int>`
+
+Maximum output sequence length cap for top-level (parent) turns. Turns with output_length > max_osl are capped to max_osl. Subagent child turns are intentionally uncapped so their decode load stays faithful; flat-chain sidecars still honor the cap.
+<br/>_Constraints: ≥ 1_
+
+### Load Generator
+
+#### `--benchmark-duration` `<str>`
+
+Maximum benchmark runtime in seconds. When set, AIPerf stops issuing new requests after this duration, Responses received within `--benchmark-grace-period` after duration ends are included in metrics. Pass a comma-separated list (e.g. `--benchmark-duration 30,60,120`) to sweep over multiple durations; the converter promotes the list to a sweep on phases.profiling.duration before AIPerfConfig validation.
+
+#### `--benchmark-grace-period` `<float>`
+
+The grace period in seconds to wait for responses after benchmark duration ends. Only applies when --benchmark-duration is set. Responses received within this period are included in metrics. Use 'inf' to wait indefinitely for all responses.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `30.0`_
+
+#### `--concurrency` `<str>`
+
+Number of concurrent requests to maintain. AIPerf issues a new request immediately when one completes, maintaining this level of in-flight requests. Can be combined with `--request-rate` to control the request rate. Pass a comma-separated list (e.g. `--concurrency 10,20,30`) to sweep over multiple concurrencies; the converter promotes the list to a sweep before AIPerfConfig validation.
+
+#### `--prefill-concurrency` `<str>`
+
+Max concurrent requests waiting for first token (prefill phase). Limits how many requests can be in the prefill/prompt-processing stage simultaneously. Pass a comma-separated list (e.g. `--prefill-concurrency 1,2,4`) to sweep over multiple values; the converter promotes the list to a sweep before AIPerfConfig validation.
+
+#### `--request-rate` `<str>`
+
+Target request rate in requests per second. AIPerf generates request timing according to `--request-rate-mode` to achieve this average rate. Can be combined with `--concurrency` to control the number of concurrent requests. Supports fractional rates (e.g., `0.5` = 1 request every 2 seconds). Pass a comma-separated list (e.g. `--request-rate 10,20,50`) to sweep over multiple rates; the converter promotes the list to a sweep before AIPerfConfig validation.
+
+#### `--arrival-pattern`, `--request-rate-mode` `<str>`
+
+Sets the arrival pattern for the load generated by AIPerf. Valid values: constant, poisson, gamma. `constant`: Generate requests at a fixed rate. `poisson`: Generate requests using a poisson distribution. `gamma`: Generate requests using a gamma distribution with tunable smoothness.
+<br/>_Choices: [`concurrency_burst`, `constant`, `gamma`, `poisson`]_
+<br/>_Default: `poisson`_
+
+#### `--arrival-smoothness`, `--vllm-burstiness` `<float>`
+
+Smoothness parameter for gamma distribution arrivals (--arrival-pattern gamma). Controls the shape of the arrival pattern: - 1.0: Poisson-like (exponential inter-arrivals, default) - &lt;1.0: Bursty/clustered arrivals (higher variance) - >1.0: Smooth/regular arrivals (lower variance) Compatible with vLLM's --burstiness parameter (same value = same distribution).
+<br/>_Constraints: > 0_
+
+#### `--request-count`, `--num-requests` `<str>`
+
+The maximum number of requests to send. If not set, will be automatically determined based on the timing mode and dataset size. For synthetic datasets, this will be `max(10, concurrency * 2)`. Pass a comma-separated list (e.g. `--request-count 100,500,1000`) to sweep over multiple request counts; the converter promotes the list to a sweep on phases.profiling.requests before AIPerfConfig validation.
+
+#### `--concurrency-ramp-duration` `<float>`
+
+Duration in seconds to ramp session concurrency from 1 to target. Useful for gradual warm-up of the target system.
+<br/>_Constraints: > 0_
+
+#### `--prefill-concurrency-ramp-duration` `<float>`
+
+Duration in seconds to ramp prefill concurrency from 1 to target.
+<br/>_Constraints: > 0_
+
+#### `--request-rate-ramp-duration` `<float>`
+
+Duration in seconds to ramp request rate from a proportional minimum to target. Start rate is calculated as target * (update_interval / duration), ensuring correct behavior for target rates below 1 QPS. Useful for gradual warm-up of the target system.
+<br/>_Constraints: > 0_
+
+#### `--request-rate-series` `<str>`
+
+JSON file containing request-rate points for piecewise-linear request-rate control.
+
+#### `--failed-request-threshold` `<float>`
+
+Abort the run early when (failed_records / total_records) exceeds this ratio. Default None disables the check. Only PROFILING-phase records count toward the ratio. A grace floor of max(concurrency, 10) records must accumulate before the check is armed, so a single early failure cannot kill the run. When the threshold is exceeded a PROFILE_CANCEL is broadcast: in-flight requests drain via the normal cancel path, partial results are still aggregated, and the run exits non-zero. Pairs with the AGENTIC_REPLAY context-overflow drop in record_processor_service so the rate measures real failures only.
+<br/>_Constraints: ≥ 0.0, ≤ 1.0_
+
+#### `--trajectory-start-min-ratio` `<float>`
+
+AGENTIC_REPLAY only: lower bound (inclusive) on the random start position within each trajectory, expressed as a fraction of the trace's total turn count. Sampled per trajectory at trajectory-build time; deterministic given --random-seed.
+<br/>_Constraints: ≥ 0.0, ≤ 1.0_
+<br/>_Default: `0.25`_
+
+#### `--trajectory-start-max-ratio` `<float>`
+
+AGENTIC_REPLAY only: upper bound (inclusive) on the random start position within each trajectory, expressed as a fraction of the trace's total turn count. The effective per-trace ceiling is min(int(max_ratio * n), n - 2) so at least one profile turn remains after warmup.
+<br/>_Constraints: ≥ 0.0, ≤ 1.0_
+<br/>_Default: `0.75`_
+
+#### `--burst-phase-starts`
+
+AGENTIC_REPLAY only: collapse the WARMUP-start and PROFILING-start dispatches into synchronized bursts instead of spreading them by each request's recorded offset from t*. By default (False) the phase starts are SPREAD: WARMUP requests are aligned globally so every trajectory reaches its t* at the same instant (the warmup end), and each lane's first PROFILING request waits out its recorded gap after t* -- reproducing the recorded arrival pattern at both phase boundaries. The rest of the replay (inter-turn delays) is timing-faithful regardless of this flag; it governs ONLY the burst-vs-spread of the two phase starts. Pass --burst-phase-starts to fire each phase's first requests together (faster concurrency ramp, synchronized start), e.g. for a throughput-oriented run rather than a faithful arrival replay.
+<br/>_Flag (no value required)_
+
+#### `--trace-idle-gap-cap-seconds` `<float>`
+
+Hard ceiling (seconds) for idle gaps within each individual trace. For Weka trace replay, AIPerf looks at all parent and subagent request submission timestamps within one root trace, compresses long gaps between consecutive request submissions, and derives turn delays from the compressed per-trace timeline. Original request api_time values are not used to decide these idle gaps. When set for Weka, this takes precedence over `--inter-turn-delay-cap-seconds` so individual parent/subagent-line delays are not separately capped. Defaults to None (no per-trace idle-gap compression).
+<br/>_Constraints: ≥ 0.0_
+
+#### `--system-idle-gap-cap-seconds` `<float>`
+
+AGENTIC_REPLAY only: maximum time in seconds the replay may remain globally idle while future requests are scheduled. When no requests are in flight or ready, all pending request timers shift earlier uniformly so the next request arrives within this limit. Per-trace timing is otherwise preserved. None disables the cap.
+<br/>_Constraints: ≥ 0.0_
+
+### Scenario
+
+#### `--scenario` `<str>`
+
+Lock all benchmark invariants for a named scenario (e.g. 'inferencex-agentx-mvp'). Conflicts with the locked invariants raise ScenarioLockError at startup unless --unsafe-override is also passed. Distinct from the sweep ``scenarios`` strategy (hand-picked named runs).
+
+#### `--unsafe-override`
+
+Convert scenario lock errors to warnings; stamps submission_valid=false in the aggregate output. No-op without --scenario.
+<br/>_Flag (no value required)_
+
+### Warmup
+
+#### `--warmup-request-count`, `--num-warmup-requests` `<int>`
+
+The maximum number of warmup requests to send before benchmarking. If not set and no --warmup-duration is set, then no warmup phase will be used.
+<br/>_Constraints: > 0_
+
+#### `--warmup-duration` `<float>`
+
+The maximum duration in seconds for the warmup phase. If not set, it will use the `--warmup-request-count` value. If neither are set, no warmup phase will be used.
+<br/>_Constraints: > 0_
+
+#### `--agentic-cache-warmup-duration` `<float>`
+
+Additional agentic replay warmup duration in seconds. After the normal snapshot warmup drains, AIPerf continues the live trajectories without recorded idle delays and with one-token outputs, then drains and resumes profiling from the resulting trajectory state using each live stream's residual next-turn delay.
+<br/>_Constraints: > 0_
+
+#### `--agentic-warmup-grace-period` `<float>`
+
+AGENTIC_REPLAY only: grace period in seconds the auto-synthesized warmup barrier waits for in-flight priming requests after the warmup burst sends. The agentic warmup is synthesized from the profiling phase rather than a user-declared warmup phase, so it does NOT honor `--warmup-grace-period` (which requires `--warmup-duration`). If not set, the warmup barrier waits indefinitely until every primed trajectory returns.
+<br/>_Constraints: ≥ 0_
+
+#### `--num-warmup-sessions` `<int>`
+
+The number of sessions to use for the warmup phase. If not set, it will use the `--warmup-request-count` value.
+<br/>_Constraints: ≥ 1_
+
+#### `--warmup-concurrency` `<int>`
+
+The concurrency value to use for the warmup phase. If not set, it will use the `--concurrency` value.
+<br/>_Constraints: ≥ 1_
+
+#### `--warmup-prefill-concurrency` `<int>`
+
+The prefill concurrency value to use for the warmup phase. If not set, it will use the `--prefill-concurrency` value.
+<br/>_Constraints: ≥ 1_
+
+#### `--warmup-request-rate` `<float>`
+
+The request rate to use for the warmup phase. If not set, it will use the `--request-rate` value.
+<br/>_Constraints: > 0_
+
+#### `--warmup-arrival-pattern` `<str>`
+
+The arrival pattern to use for the warmup phase. If not set, it will use the `--arrival-pattern` value. Valid values: constant, poisson, gamma.
+
+#### `--warmup-grace-period` `<float>`
+
+The grace period in seconds to wait for responses after warmup phase ends. Only applies when warmup is enabled. Responses received within this period are included in warmup completion. If not set, waits indefinitely for all warmup responses.
+<br/>_Constraints: ≥ 0_
+
+#### `--warmup-concurrency-ramp-duration` `<float>`
+
+Duration in seconds to ramp warmup session concurrency from 1 to target. If not set, uses `--concurrency-ramp-duration` value.
+<br/>_Constraints: > 0_
+
+#### `--warmup-prefill-concurrency-ramp-duration` `<float>`
+
+Duration in seconds to ramp warmup prefill concurrency from 1 to target. If not set, uses `--prefill-concurrency-ramp-duration` value.
+<br/>_Constraints: > 0_
+
+#### `--warmup-request-rate-ramp-duration` `<float>`
+
+Duration in seconds to ramp warmup request rate from a proportional minimum to target. Start rate is calculated as target * (update_interval / duration). If not set, uses `--request-rate-ramp-duration` value.
+<br/>_Constraints: > 0_
+
+### User-Centric Rate
+
+#### `--user-centric-rate` `<float>`
+
+Enable user-centric rate limiting mode with the specified request rate (QPS). Each user has a gap = num_users / qps between turns. Users block on their previous turn (no interleaving within a user). New users are spawned on a fixed schedule to maintain steady-state throughput. Designed for KV cache benchmarking with realistic multi-user patterns. Requires --num-users to be set.
+<br/>_Constraints: > 0_
+
+#### `--num-users` `<str>`
+
+The number of initial users to use for --user-centric-rate mode. Pass a comma-separated list (e.g. `--num-users 4,8,16`) to sweep over user counts; the converter promotes the list to a sweep on phases.profiling.users before AIPerfConfig validation.
+
+### Request Cancellation
+
+#### `--request-cancellation-rate` `<float>`
+
+Percentage (0-100) of requests to cancel for testing cancellation handling. Cancelled requests are sent normally but aborted after `--request-cancellation-delay` seconds. Useful for testing graceful degradation and resource cleanup.
+<br/>_Constraints: > 0.0, ≤ 100.0_
+
+#### `--request-cancellation-delay` `<float>`
+
+Seconds to wait after the request is fully sent before cancelling. A delay of 0 means 'send the full request, then immediately disconnect'. Requires --request-cancellation-rate to be set.
+<br/>_Constraints: ≥ 0.0_
+<br/>_Default: `0.0`_
+
+### Output
+
+#### `--output-artifact-dir`, `--artifact-dir` `<str>`
+
+Output directory for all benchmark artifacts including metrics (`.csv`, `.json`, `.jsonl`), raw data (`_raw.jsonl`), GPU telemetry (`_gpu_telemetry.jsonl`), and time-sliced metrics (`_timeslices.csv/json`). Directory created if it doesn't exist. All output file paths are constructed relative to this directory.
+<br/>_Default: `artifacts`_
+
+#### `--profile-export-prefix`, `--profile-export-file` `<str>`
+
+Base filename for ALL exported files. With prefix='foo' every output becomes `foo.csv`, `foo.json`, `foo_timeslices.{csv,json}`, `foo.jsonl`, `foo_raw.jsonl`, `foo_gpu_telemetry.jsonl`, and `foo_server_metrics.{jsonl,json,csv,parquet}`. When unset (the default), historical per-file names are used: `profile_export_aiperf.{csv,json}` for the summary, `profile_export.jsonl` and `profile_export_raw.jsonl` for records, `gpu_telemetry_export.jsonl`, and `server_metrics_export.*`. Known suffixes (e.g. `_raw.jsonl`, `_timeslices.csv`, `_server_metrics.parquet`) are stripped from the supplied value.
+
+#### `--export-level`, `--profile-export-level` `<str>`
+
+Controls which output files are generated. `summary`: Only aggregate metrics files (`.csv`, `.json`). `records`: Includes per-request metrics (`.jsonl`). `raw`: Includes raw request/response data (`_raw.jsonl`).

+| | | |
+|-------|:-------:|-------------|
+| `summary` |  | Export only aggregated/summarized metrics (most compact) |
+| `records` | _default_ | Export per-record metrics after aggregation with display unit conversion (CLI default) |
+| `raw` |  | Export raw parsed records with full request/response data (most detailed) |
+
+#### `--slice-duration` `<float>`
+
+Duration in seconds for time-sliced metric analysis. When set, AIPerf divides the benchmark timeline into fixed-length windows and computes metrics separately for each window. This enables analysis of performance trends and variations over time (e.g., warmup effects, degradation under sustained load).
+<br/>_Constraints: > 0_
+
+#### `--auto-plot`, `--no-auto-plot`
+
+Auto-invoke `aiperf plot` against the artifact directory after the benchmark completes. None = defer to recipe default (False if no recipe). True/False = explicit override. Failures are logged but do not fail the command unless --plot-required is set.
+
+#### `--plot-required`
+
+Treat auto-plot failures as fatal: re-raise so `aiperf profile` exits non-zero. Only meaningful when auto-plot is on. Default False = warn and continue.
+<br/>_Flag (no value required)_
+
+#### `--export-outputs-json`
+
+Export generated response text to outputs.json after the run. When enabled, the raw generated-text payload for each request is written to an outputs.json file in the artifact directory.

+
+#### `--mlflow-parent-run-id` `<str>`
+
+Optional MLflow parent run ID.
+
+#### `--mlflow-artifact-glob` `<list>`
+
+Artifact glob overrides for MLflow upload. Can be specified multiple times or as a comma-separated list.
+
+#### `--wandb-project` `<str>`
+
+Weights & Biases project name. Setting this enables wandb export.
+
+#### `--wandb-entity` `<str>`
+
+Weights & Biases entity (team or user). Defaults to the API key's default entity.
+
+#### `--wandb-run-name` `<str>`

+### HTTP Trace
+
+#### `--export-http-trace`
+
+Include HTTP trace data (timestamps, chunks, headers, socket info) in profile_export.jsonl. Computed metrics (http_req_duration, http_req_waiting, etc.) are always included regardless of this setting. See the HTTP Trace Metrics guide for details on trace data fields.
+<br/>_Flag (no value required)_
+
+#### `--show-trace-timing`
+
+Display HTTP trace timing metrics in the console at the end of the benchmark. Shows detailed timing breakdown: blocked, DNS, connecting, sending, waiting (TTFB), receiving, and total duration following k6 naming conventions.
+<br/>_Flag (no value required)_
+
+### Server Metrics
+
+#### `--server-metrics` `<list>`
+
+Server metrics collection (ENABLED BY DEFAULT). Automatically collects from inference endpoint base_url + `/metrics`. Optionally specify additional custom Prometheus-compatible endpoint URLs (e.g., http://node1:8081/metrics, http://node2:9090/metrics). Use `--no-server-metrics` to disable collection. Example: `--server-metrics node1:8081 node2:9090/metrics` for additional endpoints.
+
+#### `--no-server-metrics`
+
+Disable server metrics collection entirely.
+
+#### `--server-metrics-formats` `<list>`
+
+Specify which output formats to generate for server metrics. Multiple formats can be specified (e.g., `--server-metrics-formats json csv parquet`).
+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `json` | _default_ | Export aggregated statistics in JSON hybrid format with metrics keyed by name. Best for: Programmatic access, CI/CD pipelines, automated analysis. |
+| `csv` | _default_ | Export aggregated statistics in CSV tabular format organized by metric type. Best for: Spreadsheet analysis, Excel/Google Sheets, pandas DataFrames. |
+| `jsonl` |  | Export raw time-series records in line-delimited JSON format. Best for: Time-series analysis, debugging, visualizing metric evolution. Warning: Can generate very large files for long-running benchmarks. |
+| `parquet` |  | Export raw time-series data with delta calculations in Parquet columnar format. Best for: Analytics with DuckDB/pandas/Polars, efficient storage, SQL queries. Includes cumulative deltas from reference point for counters and histograms. |
+
+### Network Latency
+
+#### `--network-latency-automatic`
+
+Automatically measure network latency (DISABLED BY DEFAULT). Opens a fresh TCP connection to the endpoint throughout the run, measures the handshake RTT, and subtracts the mean from request-start-anchored latency metrics (request_latency, time_to_first_token, time_to_first_output_token). Raw metrics are preserved; adjusted values are emitted as separate network_adjusted_* metrics plus a network_rtt summary. Mutually exclusive with --network-latency-mean.
+<br/>_Flag (no value required)_
+
+#### `--network-latency-mean` `<float>`
+
+Set a fixed mean network RTT in milliseconds to subtract, bypassing active probing. Implicitly enables network latency adjustment. Mutually exclusive with --network-latency-automatic.
+<br/>_Constraints: ≥ 0.0_
+
+#### `--network-latency-ping-interval` `<float>`
+
+Seconds between TCP-handshake RTT probes during profiling (default: 1.0s). Only applies with --network-latency-automatic.
+<br/>_Constraints: > 0.0_
+
+### GPU Telemetry
+
+#### `--gpu-telemetry` `<list>`
+
+Enable GPU telemetry console display and optionally specify: (1) 'pynvml' or 'amdsmi' to use a local GPU library instead of DCGM HTTP endpoints, (2) 'dashboard' for realtime dashboard mode, (3) custom DCGM exporter URLs (e.g., http://node1:9401/metrics), (4) custom metrics CSV file (e.g., custom_gpu_metrics.csv). Default: DCGM mode with localhost:9400 and localhost:9401 endpoints. Examples: --gpu-telemetry pynvml | --gpu-telemetry amdsmi | --gpu-telemetry dashboard node1:9400.
+
+#### `--no-gpu-telemetry`
+
+Disable GPU telemetry collection entirely.
+
+### UI
+
+#### `--ui-type`, `--ui` `<str>`
+
+Select the user interface type for displaying benchmark progress. `dashboard` shows real-time metrics in a Textual TUI, `simple` uses TQDM progress bars, `none` disables UI completely. Defaults to `dashboard` in interactive terminals, `none` when not a TTY (e.g., piped or redirected output). Automatically set to `simple` when using `--verbose` or `--extra-verbose` in a TTY.
+<br/>_Choices: [`dashboard`, `none`, `simple`]_
+<br/>_Default: `dashboard`_
+
+### Multi-Run
+
+#### `--num-profile-runs` `<int>`
+
+Number of profile runs to execute for confidence reporting. Must be between 1 and 10. When set to 1 (default), runs a single benchmark. When set to >1, runs multiple benchmarks and computes aggregate statistics (mean, std, confidence intervals, coefficient of variation) across runs. Useful for quantifying variance and establishing confidence in results.
+<br/>_Constraints: ≥ 1, ≤ 10_
+<br/>_Default: `1`_
+
+#### `--profile-run-cooldown-seconds` `<float>`
+
+Cooldown duration in seconds between profile runs. Only applies when --num-profile-runs > 1. Allows the system to stabilize between runs (e.g., clear caches, cool down GPUs). Default is 0 (no cooldown).
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0.0`_
+
+#### `--confidence-level` `<float>`
+
+Confidence level for computing confidence intervals (0-1). Only applies when --num-profile-runs > 1. Common values: 0.90 (90%), 0.95 (95%, default), 0.99 (99%). Higher values produce wider confidence intervals.
+<br/>_Constraints: > 0, &lt; 1_
+<br/>_Default: `0.95`_
+
+#### `--profile-run-disable-warmup-after-first`, `--no-profile-run-disable-warmup-after-first`
+
+Disable warmup for profile runs after the first. Only applies when --num-profile-runs > 1. When True (default), only the first run includes warmup, subsequent runs measure steady-state performance for more accurate aggregate statistics. When False, all runs include warmup (useful for long cooldown periods or when testing cold-start performance).
+<br/>_Default: `True`_
+
+#### `--set-consistent-seed`, `--no-set-consistent-seed`
+
+Automatically set random seed for consistent workloads across runs. Only applies when --num-profile-runs > 1. When True (default), automatically sets --random-seed=42 if not specified, ensuring identical workloads across all runs for valid statistical comparison. When False, preserves None seed, resulting in different workloads per run (not recommended for confidence reporting as it produces invalid statistics). If --random-seed is explicitly set, that value is always used regardless of this setting.
+<br/>_Default: `True`_
+
+#### `--vary-seed-per-trial`, `--no-vary-seed-per-trial`
+
+When True, derive a distinct seed for each trial of a variation via SHA-256 over (envelope_seed, variation.label, trial). When False (default), all trials of a variation share the same seed, giving pure-runtime variance for confidence intervals. Enable when you want trials to also sample different inputs (captures end-to-end variance at the cost of conflating input noise with runtime noise in the resulting confidence statistics).
+
+#### `--convergence-metric` `<str>`
+
+Target metric name for adaptive convergence stopping. When set with --num-profile-runs > 1, enables adaptive mode that stops early once the metric stabilizes according to --convergence-mode. Uses --num-profile-runs as the maximum run cap. Example metrics: time_to_first_token, request_latency, inter_token_latency.
+
+#### `--convergence-stat` `<str>`
+
+Statistic to evaluate for convergence when using ci_width or cv mode. Common values: avg, p50, p90, p95, p99. Only applies when --convergence-metric is set.
+<br/>_Choices: [`avg`, `p50`, `p90`, `p95`, `p99`, `min`, `max`]_
+<br/>_Default: `avg`_
+
+#### `--convergence-threshold` `<float>`
+
+Threshold for convergence detection. For ci_width mode: maximum CI width as a fraction of the mean. For cv mode: maximum coefficient of variation. For distribution mode: KS test p-value threshold. When unset, each mode uses its own algorithm-specific default. Only applies when --convergence-metric is set.
+<br/>_Constraints: > 0, &lt; 1_
+
+#### `--convergence-mode` `<str>`
+
+Statistical method for convergence detection. ci_width: Stop when Student's t confidence interval width relative to mean is below threshold. cv: Stop when coefficient of variation (std/mean) is below threshold. distribution: Stop when KS test p-value indicates latest run matches prior runs (requires --export-level records or --export-level raw; rejected with --export-level summary). Only applies when --convergence-metric is set.
+<br/>_Choices: [`ci_width`, `cv`, `distribution`]_
+<br/>_Default: `ci_width`_
+
+#### `--parameter-sweep-cooldown-seconds` `<float>`
+
+Cooldown seconds between sweep variations (e.g. between --concurrency 10 and --concurrency 20). Honored by MultiRunOrchestrator when iterating plan.configs. Default 0.
+<br/>_Constraints: ≥ 0_
+<br/>_Default: `0.0`_
+
+#### `--parameter-sweep-same-seed`, `--no-parameter-sweep-same-seed`
+
+If true, every sweep variation reuses the same random seed (correlated comparisons). If false (default), each variation derives a unique seed `base_seed + variation.index` so independent draws exercise different inputs. Requires --random-seed when true.
+
+#### `--parameter-sweep-mode` `<str>`
+
+Execution order for sweep + multi-trial composition. 'repeated' (default) iterates trials as the outer loop and variations as the inner loop, so all variations run within trial 1, then within trial 2, etc. 'independent' inverts the loops: all trials at one variation complete before the next variation starts. Both modes produce the same total runs, only the artifact-path layout and submit order differ.
+<br/>_Choices: [`independent`, `repeated`]_
+<br/>_Default: `repeated`_
+
+#### `--sweep-type` `<str>`
+
+Topology used when multiple CLI magic-list flags (--concurrency, --request-rate, --isl, --osl, ...) are passed together. 'grid' (default) takes the Cartesian product of all lists; 'zip' pairs them element-wise (all lists must have equal length, like the YAML `sweep: {type: zip}` block). Ignored when only one magic-list flag is set or when the sweep is declared in YAML.
+<br/>_Default: `grid`_
+
+#### `--no-sweep-table`
+
+Suppress the per-cell streaming sweep table during multi-variation sweeps. Auto-suppressed when stdout is non-interactive, when the dashboard UI is active, or for single-cell sweeps.
+
+#### `--search-space` `<list>`
+
+Adaptive-search space dimensions. Repeatable. Each value is 'path:lo,hi[:kind]', e.g. 'phases.profiling.concurrency:1,1000:int'. Mutually exclusive with magic-list flags (--concurrency 10,20,30) and with explicit sweep blocks. See docs/sweeping/bayesian-optimization.md.
+
+#### `--search-metric` `<str>`
+
+Metric tag to optimize, e.g. 'output_token_throughput'. Required when --search-space is set. Must match a key in RunResult.summary_metrics produced by the run (NOT the flattened '_avg' / '_p99' aggregator-suffixed key).
+
+#### `--search-stat` `<str>`
+
+Statistic on the metric: avg / p50 / p90 / p95 / p99. Defaults to 'avg' when omitted (set by the CLIConfig -> AIPerfConfig converter).
+
+#### `--search-direction` `<str>`
+
+Optimization direction. Required when --search-space is set.
+
+#### `--search-max-iterations` `<int>`
+
+Maximum number of search iterations. Each iteration runs --num-profile-runs benchmarks. Required when --search-space is set.
+<br/>_Constraints: ≥ 2, ≤ 200_
+
+#### `--search-initial-points` `<int>`
+
+Random Sobol points before fitting the GP. Defaults to 5 when omitted. Must be &lt; --search-max-iterations.
+<br/>_Constraints: ≥ 1_
+
+#### `--search-random-seed` `<int>`
+
+Random seed for reproducible search trajectories. When unset, the planner uses non-deterministic randomness.
+<br/>_Constraints: ≥ 0_
+
+#### `--search-planner` `<str>`
+
+Outer-loop search planner plugin. Default `bayesian` is a curated Optuna preset that uses BoTorch qLogNEI/qLogNEHVI when the optional `botorch` extra is installed and otherwise falls back to Optuna TPE with a warning. `optuna` is the expert-mode alternative exposing `--optuna-sampler` (tpe / gp / botorch) and `--optuna-acquisition`. Explicit unavailable optional samplers raise. Third-party planners registered under the `search_planner` plugin category are accepted here. Only applies when --search-space is set.
+<br/>_Choices: [`bayesian`, `monotonic_sla`, `smooth_isotonic`, `optuna`]_
+
+#### `--optuna-sampler` `<str>`
+
+Optuna sampler selection. Only consulted when --search-planner=optuna. ``botorch`` is the preferred implicit default and requires the optional ``botorch`` extra; when the implicit default is unavailable, the planner warns and falls back to ``tpe``. Explicit ``botorch`` requests raise if the optional stack is unavailable. ``tpe`` is dep-light and ships with Optuna core. ``gp`` is Optuna's native GP-EI with inequality constraints (Optuna 4.2+) but requires ``torch``.
+
+#### `--optuna-acquisition` `<str>`
+
+Acquisition function override for the Optuna BoTorch sampler. Only consulted when --search-planner=optuna AND --optuna-sampler=botorch; rejected otherwise. ``None`` (default) lets Optuna pick (single-objective unconstrained -> LogEI per Optuna v4.x). ``logei``/``qlogei`` make that explicit. ``qnei`` selects plain noisy EI (Letham 2017). ``qlognei`` selects qLogNoisyExpectedImprovement (Ament 2023, https://arxiv.org/abs/2310.20708) -- BoTorch's strongly recommended modern noisy-EI default; requires ``botorch>=0.10``. Multi-objective variants (``qehvi``/``qnehvi``/``qlognehvi``) are accepted when ``objectives`` has length > 1; the planner rejects them on single-objective configs.
+
+#### `--optuna-terminator` `<str>`
+
+Optional posterior-regret stopping rule layered on top of the three-signal convergence check. Only consulted when --search-planner=optuna. ``regret`` selects Optuna's ``RegretBoundEvaluator`` (Makarova et al. 2022, https://proceedings.mlr.press/v188/makarova22a.html). ``emmr`` selects ``EMMREvaluator`` (Ishibashi et al. 2023, https://proceedings.mlr.press/v206/ishibashi23a.html). Both are in the same family as Wilson 2024's PRB stopping rule and ship in Optuna core (no extra dep). ``none`` (default) disables; convergence is then driven by --search-max-iterations / --improvement-patience / --plateau-cv only.
+
+#### `--search-percentile-pooling` `<str>`
+
+Percentile aggregation strategy when --search-stat is a percentile (p50/p90/p95/p99). ``mean`` (default) computes the BO objective as the arithmetic mean of per-trial percentiles across --num-profile-runs trials. ``pooled`` walks each trial's per-request profile_export.jsonl, accumulates raw samples, and computes ``np.percentile`` over the pooled bag -- exposing more tail mass than mean-of-percentiles (correct for SLO claims; same argmax for ranking on monotone problems). ``pooled`` requires --export-level records; if the JSONL is missing the planner falls back to mean with a one-time warning. Rejected when --search-stat is ``avg``.
+
+#### `--bo-constraint-mode` `<str>`
+
+Deprecated and ignored. The bayesian preset and the optuna expert mode both use Optuna's native ``constraints_func`` (Letham et al. 2019, arXiv:1706.07094), which subsumes both the soft-penalty and EIC formulations. Accepted for backwards compatibility but has no effect: the value flows through ``_converter_optionals._SWEEP_OPTIONAL_FIELDS`` to ``AdaptiveSearchSweep.constraint_mode`` (see ``aiperf.config.sweep.config``), and that field is not read by any planner.
+
+#### `--variant`, `--sweep-variant` `<list>`
+
+Repeatable: each occurrence describes one sweep variation. Format: '[name:] key=value, key=value, ...'. Keys are CLI flag names with the leading '--' stripped, in either kebab-case or snake_case (isl, osl, concurrency, request-rate / request_rate, request-count / request_count, benchmark-duration / benchmark_duration, ...). Multi-occurrence emits a ScenarioSweep. Mutually exclusive with magic-list flags, --search-recipe, and YAML-declared sweeps. Single-occurrence is rejected -- use the standalone --isl / --osl / --concurrency flags for a one-off.
+
+#### `--search-sla` `<list>`
+
+SLA filter to attach to the adaptive-search or grid path. Format: 'metric_tag:stat:op:threshold'. Stat in {avg, min, max, p1, p5, p10, p25, p50, p75, p90, p95, p99}; op in {lt, le, gt, ge}; threshold is a float in the metric's native unit. For request_error_rate, 1 means 1% (percentage points), unlike --error-rate-sla, which accepts a fraction. Repeatable. Example: --search-sla 'time_to_first_token:p95:lt:200' --search-sla 'request_error_rate:avg:lt:1'. Composes with recipe-named SLA flags (--ttft-sla-ms etc.); the final filter list is recipe filters first, then --search-sla filters in CLI order.
+
+#### `--search-sla-tier` `<list>`
+
+Multi-tier SLO grouping flag. Each invocation defines one tier of SLA filters. Format: 'LABEL:FILTER[,FILTER...]' or 'FILTER[,FILTER...]' (auto-labels tier_1, tier_2, ...). Requires 2-10 invocations. Example: --search-sla-tier 'fast:output_token_throughput:avg:gt:300,time_to_first_token:p95:lt:5000' --search-sla-tier 'standard:output_token_throughput:avg:gt:100,time_to_first_token:p95:lt:10000'. When used, all --search-sla filters are still parsed and compose with tier definitions.
+
+#### `--search-recipe` `<str>`
+
+Named search-recipe preset that expands to an adaptive-search or sweep block. Mutually exclusive with explicit --search-* flags. Recipes are registered under the search_recipe plugin category. Example: --search-recipe max-throughput-ttft-sla --ttft-sla-ms 200.
+
+#### `--ttft-sla-ms` `<float>`
+
+Time-to-first-token SLA threshold in milliseconds. Required by TTFT-SLA recipes (e.g. max-throughput-ttft-sla); ignored otherwise. Must be > 0 — a 0 or negative threshold yields an unsatisfiable filter.
+<br/>_Constraints: > 0_
+
+#### `--isl-osl-pairs` `<str>`
+
+Paired ISL/OSL workload shapes for the pareto-sweep recipe, e.g. '128/128,512/256,2048/512'. Each pair is '&lt;isl>/&lt;osl>' with positive ints; pairs are comma-separated and whitespace-tolerant. Recipe-only flag; ignored unless --search-recipe pareto-sweep is set.
+
+#### `--itl-sla-ms` `<float>`
+
+Inter-token-latency SLA threshold in milliseconds. Required by ITL-SLA recipes (e.g. max-throughput-itl-sla); ignored otherwise. Must be > 0 — a 0 or negative threshold yields an unsatisfiable filter.
+<br/>_Constraints: > 0_
+
+#### `--tpot-sla-ms` `<float>`
+
+Time-per-output-token SLA threshold in milliseconds. Maps to the `inter_token_latency` metric tag (TPOT and ITL are equivalent in this codebase). Consumed by the max-concurrency-under-sla and max-goodput-under-slo recipes; ignored otherwise. Streaming required.
+<br/>_Constraints: > 0_
+
+#### `--e2e-sla-ms` `<float>`
+
+End-to-end request-latency SLA threshold in milliseconds (p99). Maps to the `request_latency` metric tag. Consumed by the max-concurrency-under-sla and max-goodput-under-slo recipes; ignored otherwise. Available without streaming.
+<br/>_Constraints: > 0_
+
+#### `--error-rate-sla` `<float>`
+
+Maximum acceptable request error rate as a fraction in (0, 1) (e.g. 0.05 = 5%). Maps to the `request_error_rate` metric tag (avg), converting the fraction to the metric's percentage-point scale. Consumed by the max-concurrency-under-sla recipe; ignored otherwise. Available without streaming.
+<br/>_Constraints: > 0, &lt; 1_
+
+#### `--slo-attainment-fraction` `<float>`
+
+Minimum fraction of requests that must satisfy ALL configured per-request SLOs (TTFT/TPOT/E2E) for a configuration to be considered feasible by the goodput recipe. Bounded in (0, 1]. Default 0.95 matches DistServe's canonical attainment-fraction convention (https://arxiv.org/pdf/2401.09670). Consumed by the max-goodput-under-slo recipe; ignored otherwise.
+<br/>_Constraints: > 0, ≤ 1_
+
+#### `--search-style` `<str>`
+
+Search strategy for the max-concurrency-under-sla recipe. 'smooth_isotonic' (default) runs PAVA + PCHIP smooth-isotonic regression-based 1D SLA-saturation search. 'monotonic' runs a 1D binary-search via the MonotonicSLASearchPlanner (~10-20 iterations). 'bo' runs penalty Bayesian Optimization (~30 iterations). 'optuna' runs the same penalty-BO formulation via the OptunaSearchPlanner (TPE/GP/BoTorch samplers; BoTorch requires the optional botorch extra). 'grid' runs a log-spaced 8-step sweep + sla_breach_knee post-process. Recipe-only flag; ignored unless --search-recipe max-concurrency-under-sla is set.
+
+#### `--degradation-threshold` `<float>`
+
+Relative latency degradation threshold for the concurrency-ramp recipe (e.g. 0.20 = 20%). The recipe's post-process handler reports the first concurrency where p99 latency exceeds baseline * (1 + threshold). Recipe-only flag; ignored unless --search-recipe concurrency-ramp is set.
+<br/>_Constraints: > 0, &lt; 1_
+
+#### `--degradation-metric-tag` `<str>`
+
+ConcurrencyRamp post-process: metric tag for knee detection (default: request_latency). Use, e.g., 'time_to_first_token' to detect the knee on TTFT instead of end-to-end request latency. Recipe-only flag; ignored unless --search-recipe concurrency-ramp is set.
+
+#### `--degradation-stat` `<str>`
+
+ConcurrencyRamp post-process: statistic for knee detection (default: p99). Recipe-only flag; ignored unless --search-recipe concurrency-ramp is set.
+
+#### `--isl-min` `<int>`
+
+Minimum input-sequence-length for the prefill-ttft-curve recipe (default 256 when omitted). The recipe sweeps ISL on a log scale from --isl-min to --isl-max. Recipe-only flag.
+<br/>_Constraints: ≥ 1_
+
+#### `--isl-max` `<int>`
+
+Maximum input-sequence-length for the prefill-ttft-curve recipe (default 32768 when omitted). The recipe sweeps ISL on a log scale from --isl-min to --isl-max. Recipe-only flag.
+<br/>_Constraints: ≥ 1_
+
+#### `--isl-steps` `<int>`
+
+Number of log-spaced steps for the prefill-ttft-curve recipe's ISL grid (default 8 when omitted). Must be >= 2 — a single-point ramp degenerates and post-process can't compute a baseline. Recipe-only flag.
+<br/>_Constraints: ≥ 2_
+
+#### `--concurrency-min` `<int>`
+
+Lower bound for the concurrency sweep axis used by concurrency-ramp and decode-itl-curve recipes (defaults: 1 for concurrency-ramp, 1 for decode-itl-curve). Must be &lt; --concurrency-max. Recipe-only flag.
+<br/>_Constraints: ≥ 1_
+
+#### `--concurrency-max` `<int>`
+
+Upper bound for the concurrency sweep axis used by concurrency-ramp and decode-itl-curve recipes (defaults: 1000 for concurrency-ramp, 200 for decode-itl-curve). Must be > --concurrency-min. Recipe-only flag.
+<br/>_Constraints: ≥ 1_
+
+#### `--concurrency-steps` `<int>`
+
+Number of log-spaced steps for the concurrency sweep axis used by concurrency-ramp (default 8) and decode-itl-curve (default 6). Must be >= 2. Recipe-only flag.
+<br/>_Constraints: ≥ 2_
+
+#### `--osl-min` `<int>`
+
+Minimum output-sequence-length for the decode-itl-curve recipe's OSL grid (default 64 when omitted). The recipe sweeps OSL on a log scale from --osl-min to --osl-max. Recipe-only flag.
+<br/>_Constraints: ≥ 1_
+
+#### `--osl-max` `<int>`
+
+Maximum output-sequence-length for the decode-itl-curve recipe's OSL grid (default 1024 when omitted). The recipe sweeps OSL on a log scale from --osl-min to --osl-max. Recipe-only flag.

+
+#### `--accuracy-enable-cot`, `--accuracy-no-enable-cot`
+
+Enable chain-of-thought prompting for accuracy evaluation. Adds reasoning instructions to the prompt. Defaults to the benchmark's ``default_enable_cot`` metadata when unset (e.g. AIME defaults to True).
+<br/>_Flag (no value required)_
+
+#### `--accuracy-grader` `<str>`
+
+Override the default grader for the selected benchmark (e.g., exact_match, math, multiple_choice, code_execution). If not set, uses the benchmark's default grader.

+
+**Choices:**
+
+| | | |
+|-------|:-------:|-------------|
+| `TRACE` |  | Most verbose. Logs all operations including ZMQ messages and internal state changes. |
+| `DEBUG` |  | Detailed debugging information. Logs function calls and important state transitions. |
+| `INFO` | _default_ | General informational messages. Default level showing benchmark progress and results. |
+| `NOTICE` |  | Important informational messages that are more significant than INFO but not warnings. |
+| `WARNING` |  | Warning messages for potentially problematic situations that don't prevent execution. |
+| `SUCCESS` |  | Success messages for completed operations and milestones. |
+| `ERROR` |  | Error messages for failures that prevent specific operations but allow continued execution. |
+| `CRITICAL` |  | Critical errors that may cause the benchmark to fail or produce invalid results. |

+<br/>_Flag (no value required)_
+
+#### `-vv`, `--extra-verbose`
+
+Equivalent to `--log-level TRACE`. Enables the most verbose logging possible, including all ZMQ messages, internal state changes, and low-level operations. Also switches UI to `simple` mode. Use for deep debugging.
+<br/>_Flag (no value required)_
+
+#### `--record-processor-service-count`, `--record-processors` `<int>`
+
+Number of `RecordProcessor` services to spawn for parallel metric computation. Higher request rates require more processors to keep up with incoming records. If not specified, automatically determined based on worker count (typically 1-2 processors per 8 workers).
+<br/>_Constraints: ≥ 1_
+
+#### `--api-port` `<int>`
+
+AIPerf API port (enables HTTP + WebSocket endpoints).
+<br/>_Constraints: ≥ 1, ≤ 65535_
+
+#### `--api-host` `<str>`
+
+AIPerf API host (requires --api-port or AIPERF_API_SERVER_PORT to be set).
+
+#### `--stats-interval` `<float>`
+
+Interval in seconds between realtime stats publishes (dashboards and the per-tick log block). 0 disables the log block while dashboards continue to poll. Defaults to 5s under --ui dashboard, 30s otherwise. Overrides AIPERF_UI_REALTIME_METRICS_INTERVAL.
+<br/>_Constraints: ≥ 0.0, ≤ 1000.0_
+
+### Workers
+
+#### `--workers-max`, `--max-workers` `<int>`
+
+Maximum number of workers to create. If not specified, the number of workers will be determined by the formula `min(concurrency, (num CPUs * 0.75) - 1)`, with a default max cap of 32. Any value provided will still be capped by the concurrency value (if specified), but not by the max cap.
+<br/>_Constraints: ≥ 1_
+
+### ZMQ Communication
+
+#### `--zmq-host` `<str>`
+
+Host address for internal ZMQ TCP communication between AIPerf services. Defaults to `127.0.0.1` (localhost) for single-machine deployments. For distributed setups, set to a reachable IP address. All internal service-to-service communication (message bus, dataset manager, workers) uses this host for TCP sockets.
+<br/>_Default: `127.0.0.1`_
+
+#### `--zmq-ipc-path` `<str>`
+
+Directory path for ZMQ IPC (Inter-Process Communication) socket files. When using IPC transport instead of TCP, AIPerf creates Unix domain socket files in this directory for faster local communication. Auto-generated in system temp directory if not specified. Only applicable when using IPC communication backend.
+
+#### `--zmq-dual-bind`
+
+Select the ZMQ dual-bind communication backend (IPC + TCP). All dual-bind knobs are cluster-managed; this flag only selects the discriminator and the converter routes downstream to the default.
+<br/>_Flag (no value required)_

+
+## `aiperf plot`
+
+Generate visualizations from AIPerf profiling data.
+
+On first run, automatically creates ~/.aiperf/plot_config.yaml which you can edit to customize plots, including experiment classification (baseline vs treatment runs). Use --config to specify a different config file.
+
+_**Note:** PNG export requires Chrome or Chromium to be installed on your system, as it is used by kaleido to render Plotly figures to static images._
+
+_**Note:** The plot command expects default export filenames (e.g., `profile_export.jsonl`). Runs created with `--profile-export-file` or custom `--profile-export-prefix` use different filenames and will not be detected by the plot command._

+## CLI flag routing under `--config`
+
+`resolve_config` merges a YAML config file with explicitly-set CLI
+flags. Historically it only knew how to route a subset of `CLIConfig`
+into the merged dict, and **every other flag was discarded without a
+word** — `aiperf profile -f base.yaml --random-seed 42` ran with a
+different seed than the user asked for and said nothing. For a
+benchmarking tool that silently corrupts published numbers.
+
+The invariant now in force:
+
+> A CLI flag passed alongside `--config` either changes the resolved
+> config, or raises an error naming the flag. It is never silently
+> ignored.
+
+### `CLIConfig` is the source of truth
+
+The guarantee is scoped to what `resolve_config` can see, and its
+signature is the boundary:
+
+```python
+def resolve_config(cli_config: CLIConfig, config_file: Path | None = None) -> AIPerfConfig
+```
+
+Both entry points — `aiperf profile` and `aiperf service` — call it with
+nothing but their `CLIConfig` and a path. So a CLI option can influence
+the resolved `AIPerfConfig` **only** by being a field on `CLIConfig`,
+and that is a structural property of the call, not a convention someone
+has to remember. It is what lets the classification test enumerate
+`CLIConfig.model_fields` and claim completeness: there is no second
+source of flags for it to miss.
+
+Two consequences worth stating plainly:
+
+- **Command-level parameters are out of scope, by construction.**
+  `aiperf service` declares `--service-id`, `--health-host`,
+  `--health-port` and its `service_type` argument directly on the
+  command function rather than on `CLIConfig`. They are service-instance
+  plumbing, never passed to `resolve_config`, and so cannot be dropped
+  by this mechanism — they never enter it. Anything that *is* benchmark
+  configuration belongs on `CLIConfig`, precisely so this guarantee
+  covers it.
+- **The assumption is falsifiable, and this is how it would break.**
+  Giving `resolve_config` another parameter that carries user intent, or
+  having it read flags from module state or the environment, puts values
+  into the resolved config that no test enumerates. If you need to do
+  that, extend the classification to cover the new source in the same
+  breath — otherwise the suite will keep reporting a completeness it no
+  longer has.
+
+Every field on `CLIConfig` must be classified in
+[`_config_flag_routing.py`](https://github.com/ai-dynamo/aiperf/tree/main/src/aiperf/config/flags/_config_flag_routing.py):
+
+| Set | Meaning |
+| --- | --- |
+| `ROUTED_UNDER_CONFIG` | Reaches `AIPerfConfig`. Derived from the resolver's own routing tables where possible, so it cannot drift from them. |
+| `UNROUTED_UNDER_CONFIG` | Known not to route. Raises `ConfigurationError` naming the flag. |
+| `EXEMPT_FROM_CONFIG_ROUTING` | Not benchmark config at all (`--config` itself). Each entry needs a stated reason. |
+| `COMPANION_ROUTED` | Routes only alongside another flag (`--model-selection-strategy` needs `--model-names`). Rejected when the companion is absent. |
+| `MAGIC_LIST_ONLY_UNDER_CONFIG` | Routes in list form only (`--isl 128 256` becomes a sweep parameter; scalar `--isl 128` goes to the dataset). Decided per value. |
+
+### Why the guarantee holds
+
+Four layers, each covering the previous one's blind spot:
+
+1. **The universe is derived, not maintained.** Every set is
+   subtracted from `frozenset(CLIConfig.model_fields)`. You cannot add
+   a CLI option without adding a field, so nothing is checked against
+   a list someone has to remember to update.
+2. **Runtime is default-deny.** `reject_unrouted_cli_flags` computes
+   `model_fields_set - ROUTED - EXEMPT` and raises on the remainder —
+   "is this known-good?", not "is this known-bad?". It gates on
+   `model_fields_set`, never truthiness, so `--prompt-batch-size 0`
+   counts as set.
+3. **Classification is mandatory.**
+   `test_every_cli_config_field_is_classified` fails when a field
+   belongs to none of the sets, so a new flag fails CI at authoring
+   time.
+4. **The classification is verified, not trusted.** Layer 3 only
+   proves someone applied a label.
+   `test_routed_field_never_silently_no_ops` drives every routed field
+   against both a synthetic and a file dataset and asserts it changes
+   the config or raises. This is what catches whole-section
+   classifications (`OUTPUT`/`TOKENIZER`/`ACCURACY`/`SWEEPING` are
+   marked routed wholesale, so a new member is auto-classified and
+   layer 3 passes vacuously).
+
+Two further invariants guard the merge itself:
+`test_override_emits_no_key_the_user_did_not_set` runs `build_dataset`
+twice with different values for one field — any emitted key identical
+across both runs is a materialized default that would overwrite a YAML
+value the user never mentioned. `test_routed_dataset_field_actually_changes_the_resolved_config`
+covers the dataset block specifically.
+
+### Adding a new CLI flag
+
+1. Add the field to `CLIConfig` as usual. CI now fails with
+   `CLI fields are unclassified for the --config path: [...]`.
+2. Decide what the flag should do under `--config`:
+   - **Route it** (preferred). Dataset-shaping fields flow through
+     `build_dataset` automatically. Otherwise wire it into
+     `build_cli_overrides` — check first whether a builder already
+     exists, as `build_mlflow`/`build_otel`/`build_network_latency`
+     did while going uncalled.
+   - **Or list it in `UNROUTED_UNDER_CONFIG`**, so users get an error
+     naming the flag rather than a wrong benchmark.
+3. If the invariant suite cannot generate a value from the
+   annotation (`typing.Any`, free-form strings), add one to
+   `FIELD_PROBE_VALUES` or list the field in `UNDRIVABLE_FIELDS` with
+   a reason. Do not let it report as skipped — a skip is invisible in
+   CI, which is exactly how a coverage hole hides.
+
+### Known gaps
+
+`--sweep-type` and `--disable-auto-fixed-schedule` are unrouted and
+loud: the first needs a sweep block to attach to, the second is
+consumed during phase construction, which this path does not rebuild.
+
+The flags in `SWEEP_FIELDS_NOT_ROUTED` (`--concurrency-min/max/steps`,
+`--isl-*`/`--osl-*`, the `*-sla-ms` filters, `--parameter-sweep-*`)
+resolve cleanly and change nothing, so they are rejected. Verified
+individually — notably `--ttft-sla-ms` does **not** take effect even
+alongside `--search-recipe` and `--streaming`. Routing them is
+follow-up work; until then the failure is loud.
+

+
+`WorkerGroupManager` is the readiness and capacity authority for each Kubernetes worker pod. Local multiprocessing is managed directly by `MultiProcessServiceManager` and `WorkerManager`.
+
+## 1. CLI Entry Point
+
+```bash
+aiperf kube profile --model Qwen/Qwen3-0.6B --url http://server:8000 --image aiperf:latest --total-workers 10
+```
+
+CLI commands defined in `src/aiperf/cli_commands/kube/`:
+
+| Command | Purpose |
+|---------|---------|
+| `init` | Generate a starter configuration template |
+| `validate` | Validate AIPerfJob and AIPerfSweep YAML files against the CRD schema |
+| `profile` | Run a benchmark in Kubernetes |
+| `sweep` | Run a parameter sweep or multi-run benchmark in Kubernetes |
+| `generate` | Generate Kubernetes YAML manifests |
+| `delete` | Delete a benchmark and its backing Kubernetes resources |
+| `cleanup` | Bulk-remove finished benchmarks from a namespace |
+| `shutdown` | Retire a finished benchmark's controller pod |
+| `cancel` | Cancel a running benchmark (patches `spec.cancel` on the CR) |
+| `attach` | Attach to a running benchmark and stream progress |
+| `list` | List benchmark jobs and their status; pass `--watch` for live updates |
+| `logs` | Retrieve logs from benchmark pods |
+| `results` | Retrieve benchmark results |
+| `show` | Render an AIPerfJob CR with Jinja2/env-vars resolved |
+| `debug` | Run diagnostic analysis on a deployment |
+| `preflight` | Run pre-flight checks against the target cluster |
+| `dashboard` | Open the operator results server UI in your browser |
+
+## 2. Deployment Generation
+
+The deployment logic in `src/aiperf/cli_commands/kube/profile.py` auto-detects whether the AIPerfJob CRD is installed. If the operator is present, `deploy_via_operator()` (in `profile_deploy.py`) submits an `AIPerfJob` custom resource and the operator reconciles it; otherwise `deploy_direct()` (in `profile_deploy_direct.py`) creates the manifests (ConfigMap, Role, RoleBinding, JobSet) directly. `--operator` forces operator mode without the cluster-scoped CRD probe; `--no-operator` forces direct mode. Both paths require the target namespace to exist — neither creates one. Pass `--namespace` explicitly or set a default in your kubeconfig context.
+
+```mermaid
+flowchart TD
+    A["1. Resolve benchmark config<br/>from CLI flags or AIPerfJob CR YAML"] --> B
+    B["2. Configure ServiceConfig<br/>service_run_type = KUBERNETES<br/>dataset API base URL = controller DNS"] --> C
+    C{"3. AIPerfJob CRD present?"}
+    C -->|yes, or --operator| D["Operator mode:<br/>create AIPerfJob CR, operator reconciles"]
+    C -->|no, or --no-operator| E["Direct mode:<br/>create ConfigMap + RBAC + JobSet directly"]
+```
+
+`ServiceRunType.KUBERNETES` is a generated plugin enum member — it comes from
+`src/aiperf/plugin/plugins.yaml` via the generated `src/aiperf/plugin/enums.py`,
+which is never hand-edited.
+
+## 3. Kubernetes Resources
+
+### Resource Creation Order
+
+```mermaid
+flowchart TD
+    ROLE[Role] --> RB[RoleBinding]
+    ROLE --> CM[ConfigMap]
+    RB --> CM
+    CM --> JS[JobSet]
+    JS --> CTRL["controller (1 pod)"]
+    JS --> W["workers (N pods)"]
+```
+
+### Same-name recreation fencing
+
+Operator-managed RBAC, ConfigMaps, and JobSets are adopted after an
+`AlreadyExists` response only when their controller owner reference matches the
+current AIPerfJob or AIPerfSweep name and immutable UID. A resource owned by an
+older incarnation, or a matching resource already being deleted, remains on a
+retry path until Kubernetes garbage collection finishes. A deterministic name
+occupied by an unrelated or ownerless resource fails permanently instead of
+being adopted.
+
+Sweep child rollups and the sweep-controller pod apply the same UID fence to
+parent status writes. Resource-version and JSON Patch test operations prevent a
+delayed child event or stale controller pod from updating a newly recreated,
+same-named AIPerfSweep.
+
+AIPerfJob recovery callbacks also pin the parent resource version and accept
+JobSet state only when its controller owner API version, kind, name, and UID
+match the callback's immutable parent UID. Timeout, startup-failure, and result
+salvage cleanup re-read that ownership and delete with the JobSet UID as a
+precondition. A stable startup-blocker deadline first atomically adds
+`aiperf.nvidia.com/startup-failure-claimed` with JSON Patch tests for the
+parent UID, resource version, spec cancellation state, phase, exact
+`status.startupIssue`, and annotation map. The annotation-map test makes this
+failure-cleanup claim mutually exclusive with the durable completion claim;
+only the winner may enter JobSet deletion. A matching persisted failure claim
+resumes cleanup after an operator restart. Pod watches and stale-heartbeat
+recovery only persist critical startup diagnosis; the cached-state deadline is
+the sole path that may claim, delete, and terminalize that blocker. JobSet
+failure events use the same ownership fence before a direct status patch.
+Event status changes are rebased onto the fenced live status so every condition
+type not demonstrably changed by the event survives concurrent controller
+writes. Pod events resolve the full Pod to batch Job to JobSet to AIPerfJob
+controller-owner chain before restart reporting, startup diagnosis, or
+controller-termination salvage; transient owner-read failures request a
+bounded kopf retry instead of dropping the one-shot event.
+
+For an operator-managed AIPerfJob, the immutable owner UID is injected into
+controller-pod services as `AIPERF_JOB_UID`. Completion and progress writers
+read the live target, verify ownership, and use JSON Patch `test` operations on
+the AIPerfJob or JobSet UID before adding annotations. If the named resource was
+recreated between the read and patch, the API server rejects the whole atomic
+patch and the stale controller cannot mutate the replacement.
+
+Cancellation and completion callbacks use the same UID in their process-local
+cancellation, progress-client, and completion-claim keys. JobSet deletion uses
+the validated JobSet UID as a precondition, and terminal status merge patches
+carry the live parent resource version. Ready/latest and runs-index publication
+recheck the parent UID; the SQLite latest row advances only when `latest.txt`
+accepted the same epoch. A delayed callback therefore cannot close a
+replacement job's client, delete its JobSet, or publish terminal state for it.
+
+AIPerfSweep deletion uses sweep-name, sweep-UID, and, when available, run-epoch
+labels only to discover candidate child jobs. Before setting
+`spec.cancel=true`, the handler requires an `AIPerfSweep` owner reference whose
+name and immutable UID match the deleting parent. A standalone AIPerfJob cannot
+be cancelled merely by carrying user-writable sweep tracking labels.
+
+### Pod Architecture
+
+Each control-plane service runs in its own container in the controller pod
+(sibling containers, not subprocesses). Workers and record processors
+likewise each run in their own container inside a worker pod.
+
+**Controller pod** (container names from the `Containers` class in `src/aiperf/kubernetes/constants.py`):
+
+| Container | Role |
+|---|---|
+| `control-plane` | SystemController (orchestration) |
+| `dataset-manager` | Generates prompts, serves dataset |
+| `timing-manager` | Schedules requests, issues credits |
+| `records-manager` | Aggregates results from workers |
+| `api` | WebSocket + HTTP on port 9090 |
+| `gpu-telemetry-manager` | GPU metrics via DCGM (optional) |
+| `server-metrics-manager` | Prometheus metrics (optional) |
+| `results-sidecar` | Serves exported results after controller exit (port 9091) |
+| `event-bus-proxy` | XPUB/XSUB ZMQ proxy sidecar (`AIPERF_K8S_EVENT_BUS_SIDECAR_ENABLED=true` by default; isolates pub/sub I/O from the SystemController process) |
+
+Per-container health ports run 8080-8088 (`AIPERF_K8S_PORT_*_HEALTH`); the API
+service is on 9090 and the results sidecar on 9091.
+
+**Worker pod (x N):**
+
+| Container | Role |
+|---|---|
+| `worker-group-manager` | Group-local readiness, dataset download, proxy |
+| `worker-0` .. `worker-{N}` | One worker per container; each makes LLM API calls |
+| `record-processor-0` .. `record-processor-{M}` | One record processor per container; each computes metrics per record |
+
+### RBAC Permissions
+
+The Role rules are the `_RULES` class-var on `RBACSpec` in
+`src/aiperf/kubernetes/resources.py`:
+
+| API group | Resources | Verbs |
+|---|---|---|
+| `aiperf.nvidia.com` | `aiperfjobs`, `aiperfjobs/status` | get, list, watch, patch |
+| `""` (core) | `configmaps` | get, list, watch |
+| `""` (core) | `pods`, `pods/log` | get, list, watch |
+| `""` (core) | `services`, `endpoints` | get, list, watch |
+| `""` (core) | `events` | get, list, watch |
+| `batch` | `jobs` | get, list, watch |
+| `jobset.x-k8s.io` | `jobsets` | get, list, watch, patch |
+| `jobset.x-k8s.io` | `jobsets/status` | get, list, watch |
+
+`patch` on `aiperfjobs`/`aiperfjobs/status` and `jobsets` is the only write verb
+in the set, because controller and worker pods share one ServiceAccount and the
+projected token is mounted in every container — so a worker inherits whatever
+the controller holds. Everything a pod actually writes is an annotation or
+`status` JSON-patch on its own AIPerfJob and JobSet. `create` on `jobsets` was
+removed: it let any pod launch a JobSet, and therefore run arbitrary containers,
+under the benchmark ServiceAccount.
+
+Two tests keep this pinned and keep the Python and Helm copies in sync:
+`TestRBACSpecLeastPrivilege` and `test_helm_benchmark_rbac_is_subset_of_rbac_spec`,
+both in `tests/unit/kubernetes/test_resources.py`. The chart's benchmark Role
+(`deploy/helm/aiperf-operator/templates/benchmark-rbac.yaml`) must stay a subset
+of `_RULES`, so widening one without the other fails CI.
+
+## 4. Inter-Pod Communication
+
+### Network Topology
+
+```mermaid
+flowchart TD
+    DNS["Kubernetes DNS<br/>{jobset}-controller-0-0.{jobset}.{ns}.svc.cluster.local"]
+    DNS --> W0["Worker pod 0"]
+    DNS --> W1["Worker pod 1"]
+    DNS --> WN["Worker pod N"]
+```
+
+Each worker pod resolves the controller through that headless-service DNS name,
+injected as `AIPERF_K8S_ZMQ_CONTROLLER_HOST` (the `AIPERF_K8S_ZMQ_` settings in
+`src/aiperf/kubernetes/environment.py`).
+
+### Communication Channels
+
+| Channel | Port | Protocol | Purpose |
+|---------|------|----------|---------|
+| ZMQ Event Bus | IPC + TCP | ZMQ PUB/SUB | Message broadcasting (every message type except commands) |
+| ZMQ Control Channel | IPC + 5667 | ZMQ DEALER/ROUTER | Registration, heartbeats, status, commands |
+| API Service | 9090 | HTTP/WS | WebSocket streaming, Dataset API |
+| Health | 8080 | HTTP | Kubernetes probes |
+
+### Dual-Bind ZMQ Configuration
+
+```mermaid
+flowchart TD
+    CP["Controller pod"]
+    CP --> IPC["IPC socket: event_bus_proxy_frontend.ipc<br/>used by control-plane services in the same pod"]
+    CP --> TCP["TCP sockets: 0.0.0.0:5663 (frontend), :5664 (backend)<br/>used by worker pods (external)"]
+```
+
+Port defaults live on the `AIPERF_K8S_PORT_` settings in
+`src/aiperf/kubernetes/environment.py`.
+
+### Control Channel (`CommAddress.CONTROL`)
+
+`CommAddress.CONTROL` is bound, not just declared. `SystemController` binds a
+ROUTER there with `ROUTER_MANDATORY`; every component service — in the
+controller pod and in every worker pod — connects a DEALER whose ZMQ identity is
+its service ID. Registration, heartbeats, lifecycle status, and all commands
+ride this socket as `msgspec` structs.
+
+It dual-binds the same way the event-bus proxies do, but from the
+`SystemController` rather than from a proxy:
+
+```mermaid
+flowchart TD
+    SC["SystemController<br/>ROUTER (ROUTER_MANDATORY)"]
+    SC --> IPCB["IPC bind: control.ipc<br/>control-plane services in the controller pod"]
+    SC --> TCPB["TCP bind: tcp://0.0.0.0:5667<br/>services in remote worker pods"]
+
+    LOCAL["Timing / Dataset / Records / ...<br/>DEALER over IPC"] --> IPCB
+    REMOTE["WorkerGroupManager, Workers,<br/>Record Processors<br/>DEALER over TCP"] --> TCPB
+```
+
+Which address a *connecting* service resolves is decided by
+`ZMQDualBindConfig.control_address`: `tcp://{controller_host}:{control_tcp_port}`
+when `AIPERF_K8S_CONTROLLER_HOST` is set (worker pods), and the IPC path
+otherwise (controller pod). The controller adds the TCP bind via
+`control_tcp_bind_address` only when it is itself the controller — that is, when
+`controller_host` is unset. Port default: `control_tcp_port = 5667`.
+
+**The ROUTER lives outside the comms lifecycle.** It is created with
+`attach_lifecycle=False`, in `SystemController.__init__` rather than in a
+lifecycle hook, because it must bracket the comms layer on both ends:
+
+- It must be listening *before* comms starts, since services register during
+  their own startup and a missed registration would stall the run.
+- It must outlive `comms.stop()`, because children are told to shut down over
+  this very socket. A lifecycle-attached ROUTER would be torn down as part of
+  the shutdown it is supposed to deliver.
+
+Consequently `SystemController` owns the ROUTER's initialize/start/stop itself.
+Service-side DEALERs are ordinary lifecycle children of `self.comms`, so their
+`@on_init` hook only registers the receiver — driving them a second time raises
+`InvalidStateError`.
+
+`ROUTER_MANDATORY` makes a send to an unknown or departed identity raise
+`EHOSTUNREACH` instead of silently dropping. That is intentional: a broadcast
+during teardown will legitimately hit services that have already exited, so
+`_broadcast_control_command` swallows per-peer send errors, while a targeted
+request surfaces them.
+
+## 5. Dataset Transfer
+
+In Kubernetes mode, the DatasetManager streams conversations directly to zstd-compressed files.
+Workers download the compressed files via HTTP and decompress locally for memory-mapped access.
+
+### Metadata Synchronization
+
+The API Service waits for dataset metadata before serving files:
+
+```mermaid
+sequenceDiagram
+    participant DM as DatasetManager
+    participant API as API Service
+    participant WGM as WorkerGroupManager
+
+    DM->>DM: stream_writer.write() (zstd streaming to .zst)
+    DM->>DM: finalize() + compress index
+    DM->>API: DatasetConfiguredNotification (ZMQ pub/sub)
+    Note over API: sets the dataset-configured event<br/>and caches the client metadata
+    WGM->>API: GET /api/dataset/data (Accept-Encoding: zstd)
+    Note over API: waits on the dataset-configured event,<br/>serves paths from the metadata
+    API-->>WGM: stream .zst as-is (Content-Encoding: zstd)
+    Note over WGM: decompress, then mmap locally
+    WGM->>API: GET /api/dataset/index
+    API-->>WGM: stream .zst as-is
+    Note over WGM: decompress
+```
+
+Net effect: only `.zst` files exist on the control plane, file serving is
+metadata-driven, and each worker pod ends up with local `.dat` files for mmap
+access.
+
+### Key Components
+
+| Component | Responsibility |
+|-----------|----------------|
+| **DatasetManager** | Streams to `.zst`, broadcasts `DatasetConfiguredNotification` with `MemoryMapClientMetadata` |
+| **API Service** | Waits for notification via `asyncio.Event`, serves files using paths from metadata |
+| **WorkerGroupManager** | Downloads via HTTP, decompresses within its Kubernetes worker pod, then exposes dataset readiness and current-state snapshots to sibling workers |
+
+### Benefits
+
+| Approach | Disk on Controller | Transfer | CPU Overhead |
+|----------|-------------------|----------|--------------|
+| **compress_only mode** | Compressed only | Passthrough | Compress once, decompress distributed |
+| On-the-fly compression | Uncompressed + compressed | Re-compress per request | High on controller |
+
+### Files Created
+
+**Controller (DatasetManager):**
+```
+{mmap_base}/aiperf_mmap_{benchmark_id}/
+├── dataset.dat.zst   # zstd-compressed conversations (streaming write)
+└── index.dat.zst     # zstd-compressed byte offset index
+```
+
+**Workers (after download):**
+```
+{mmap_base}/aiperf_mmap_{benchmark_id}/
+├── dataset.dat       # Decompressed conversations (mmap target)
+└── index.dat         # Decompressed index
+```
+
+## 6. Benchmark Execution Flow
+
+```mermaid
+flowchart LR
+    A[Pods start] --> B[Dataset ready]
+    B --> C[Timing credits]
+    C --> D[Workers execute]
+    D --> E[Metrics compute]
+    E --> F[Records aggregate]
+    F --> G[Results export]
+```
+
+### Detailed Steps
+
+1. **Pods Start** - Control-plane services register with `SystemController`, and each worker pod brings up one `WorkerGroupManager` as the controller-facing authority for that group
+2. **DatasetManager** - Generates prompts, serves via HTTP at `/api/dataset`
+3. **WorkerGroupManager** - Downloads dataset files once per Kubernetes worker pod, publishes current state, and makes sibling workers dispatchable only after readiness converges
+4. **TimingManager** - Schedules requests, issues credits to workers
+5. **Workers** - Make LLM API calls once their `WorkerGroupManager` reports group-local readiness, then generate raw records
+6. **RecordProcessor** - Computes metrics (latency, TTFT, throughput)
+7. **RecordsManager** - Aggregates results from all workers
+
+### Service Discovery
+
+`KubernetesServiceManager` in `src/aiperf/kubernetes/controller/kubernetes_service_manager.py`:
+
+| Method | Behavior |
+|--------|----------|
+| `run_service()` | For service types in `EXTERNAL_K8S_SERVICES`, spawns nothing — records the expected instance count with `ServiceRegistry` and waits for the sibling container/worker pod to register. Anything else falls through to `MultiProcessServiceManager.run_service` and spawns a subprocess. |
+| `stop_service()` | No-op for externally managed pods (they get shutdown over the control channel and exit on their own); otherwise delegates to the multiprocess manager. |
+| `shutdown_all_services()` | Marks shutdown complete and stops any locally managed subprocesses; the subprocess half is usually empty because sibling containers come straight from the pod spec. |
+| `check_pods_healthy()` / `_monitor_worker_pods()` | Polls worker-pod status so a crash-looping or evicted pod surfaces as a controller-side failure. |
+
+`wait_for_all_services_registration()` is overridden here (via `ServiceRegistry.wait_for_all`) so the gate counts every expected service *instance*, not just one per service type, and is what actually blocks until they have all registered over ZMQ.
+
+`SystemController` consumes both halves: `_verify_pods_healthy()` gates `PROFILE_START` on `check_pods_healthy()` (catching a pod that registered and then died), and `_watch_pod_failure_abort()` waits on `pod_failure_abort_event` so a mid-run breach of `AIPERF_POD_FAILURE_ABORT_THRESHOLD_PERCENT` cancels the benchmark through the same path as Ctrl+C. `BaseServiceManager` supplies inert defaults, so non-Kubernetes modes need no branch at the call site.
+
+### Dual-Channel Credit Readiness Gate
+
+Credits are dispatched controller -> worker on ROUTER/DEALER (`CommAddress.CREDIT_ROUTER`) and returned worker -> controller on a separate PUSH/PULL fan-in (`CommAddress.CREDIT_RETURN`), with the worker id carried in-message because PUSH/PULL has no envelope identity. The two sockets come up independently — the router binds ROUTER before PULL, and each worker connects each socket on its own schedule — so a DEALER that has handshaked proves nothing about the return half.
+
+`Worker._await_return_channel_ready` closes that gap: before sending `WorkerDispatchable` the worker probes its credit-return PUSH socket via `aiperf.workers.return_channel_probe.probe_return_channel`, which retries a NOBLOCK send of `WorkerConnected` until libzmq accepts it. `IMMEDIATE=1` is what makes this a real liveness test — libzmq refuses the send with `zmq.Again` while no peer pipe exists — and the probe needs no reply, which matters because PUSH/PULL is unidirectional. The probe frame is a real `WorkerConnected` that the router already handles idempotently on the PULL path, so the message finally means what it says: the *return* path is connected.
+
+The gate is bounded by `AIPERF_WORKER_RETURN_PROBE_BUDGET` (attempts spaced by `AIPERF_WORKER_RETURN_PROBE_RETRY_DELAY`, 0 disables) and degrades open on expiry with a warning: `ZMQStreamingPushClient` parks unsendable returns in an unbounded backlog and drains them on reconnect, so a late return channel costs latency, whereas never announcing dispatchability costs the run.
+
+### Cross-Pod Clock Correction
+
+Controller and worker pods have independent clocks. Every credit carries the controller's `issued_at_ns`, so each receipt is a one-way offset sample (`received - issued`) fed to `ClockOffsetTracker`, which min-filters a 20-sample window (NTP RFC 5905 clock filter) to reject transit jitter. That minimum is still `skew + min_transit`, so the transit term is removed separately: at startup a worker sends `TimePing` on its credit DEALER, `StickyCreditRouter._handle_time_ping` echoes `TimePong` verbatim so RTT is measured entirely against the worker's own clock, and half the minimum RTT is subtracted from the sample. Every `RequestRecord` leaving a worker is stamped with that combined value (`ClockOffsetTracker.correction_ns`, which degrades to the raw sample if no RTT baseline was established) as `clock_offset_ns`; the contract is `controller_time = worker_time - clock_offset_ns`. Both sampling and probing are gated on Kubernetes mode (`Worker._tracks_clock_offset`) — in local mode both sides share one clock, so records carry `None`.
+
+## 7. Results Collection
+
+### Data Flow
+
+```mermaid
+flowchart LR
+    W["Workers (raw records)"] --> RP[RecordProcessor]
+    RP --> RM[RecordsManager]
+    RM --> API["API Service (port 9090)"]
+```
+
+In operator mode, results are served by the `results-server` container inside the operator deployment (port 8081), which reads from the operator PVC. In direct mode (no operator) or when the operator PVC is unavailable, results can be copied from the controller pod's `results-sidecar` or via `kubectl cp`.
+
+The same `results-server` container also hosts every `/api/v1/*` router for the operator (jobs, sweeps, results, config, admin, analytics, dashboard_proxy) — there is no separate FastAPI app in the operator container, which only runs kopf (`/healthz` on port 8080 and the Prometheus `/metrics` endpoint on port 9090). The sweep-controller's empty-summary fallback (`K8sChildJobExecutor._fetch_summary_from_operator`) targets this container too via `AIPERF_OPERATOR_BASE_URL` (default `http://aiperf-operator.aiperf-system:8081`); it does not point at the operator container's port 8080.
+
+### Retrieval Methods
+
+```bash
+# Operator mode (default): fetch via operator results-server
+aiperf kube results {job_id}
+
+# Direct mode / fallback: copy from the controller pod
+aiperf kube results {job_id} --from-pods
+kubectl cp <controller-pod>:/results ./results -n <namespace>
+```
+
+## Results layout and history
+
+Each AIPerfJob submission lands in its own artifact directory keyed by the CR's
+**creationTimestamp epoch** (seconds since 1970). Re-creating a CR with the
+same name never overwrites prior results.
+
+On-disk shape under the operator's results PVC (`AIPERF_RESULTS_DIR`, default
+`/data`):
+
+```text
+<base>/<namespace>/<name>/
+  <epoch-A>/   ← run A artifacts
+  <epoch-B>/   ← run B artifacts
+  latest.txt   ← pointer to the epoch of the most recent successful run
+```
+
+The pointer file is written atomically (staged write + `os.replace`) at the
+single success gate in `handlers/completion.py`, alongside `status.resultsPath`
+and `status.runEpoch`. A retention pass (env `AIPERF_RESULTS_RETAIN_RUNS`,
+default 10) trims older run dirs on every successful completion; the just-written
+epoch is always protected from deletion.
+
+### HTTP API
+
+Every route that reaches a concrete result artifact requires an explicit run
+epoch and returns `409 Conflict` if it is omitted. Callers must use the
+`/runs/<epoch>` form; there is no implicit "latest run" fallback
+(`_require_epoch_for_results` raises `HTTPException(409)` in
+`src/aiperf/operator/routers/results_files.py`). Pure discovery routes stay
+epoch-free, because they exist to tell a caller which epochs there are.
+
+| Route | Behavior |
+|---|---|
+| `GET /api/v1/results` | List every namespace/job that has stored results |
+| `GET /api/v1/results/<ns>/<name>/runs` | Run history for one job, newest first |
+| `GET /api/v1/results/<ns>/<name>` | **409** — epoch required |
+| `GET /api/v1/results/<ns>/<name>.zip` | **409** — epoch required |
+| `GET /api/v1/results/<ns>/<name>/<filename>` | **409** — epoch required |
+| `GET /api/v1/results/<ns>/<name>/runs/<epoch>` | List files from the pinned run |
+| `GET /api/v1/results/<ns>/<name>/runs/<epoch>.zip` | Zip bundle of the pinned run |
+| `GET /api/v1/results/<ns>/<name>/runs/<epoch>/<filename>` | Download one file from the pinned run |
+
+`<epoch>` is validated against `EPOCH_RE` (`\A\d{9,10}(\d{6})?\Z`, in `src/aiperf/common/results_markers.py`) before any disk access, and a non-matching value is rejected with `422` — epoch-seconds, optionally carrying the single six-digit microsecond/uid suffix `epoch_key_from_body` appends.
+
+### Edge cases
+
+- **Rapid delete + resubmit within the same wall-clock second** does not collide:
+  `epoch_key_from_body` appends a deterministic six-digit suffix derived from the
+  CR's immutable `metadata.uid` (or the real microseconds, for a fractional
+  `creationTimestamp`), so the two submissions land in distinct directories.
+  A body with no uid falls back to bare epoch-seconds, matching the legacy
+  `EPOCH=$(date +%s)` semantics.
+- **A delayed older completion never rolls the pointer backward.**
+  `write_latest` reads the current pointer first and no-ops when it already
+  names a wall-clock-newer epoch. The comparison is on the leading
+  whole-seconds component (`_epoch_wall_seconds`), not the full suffixed key,
+  because the uid and microsecond suffix spaces overlap.
+- **`latest.txt` points at a missing directory** (corruption, manual delete):
+  default-route requests return 404 until the next successful completion
+  rewrites the pointer. Historical routes still work.
+- **A `creationTimestamp` that cannot produce a storable epoch is rejected at
+  admission.** `epoch_key_from_body` is arithmetic on `creationTimestamp`, so a
+  pre-1970 value yields a negative, `EPOCH_RE`-failing key
+  (`1969-04-25T18:22:03Z` -> `-21620277`). Because the epoch is a directory
+  name, an unstorable key would desync the two halves of the sweep harvest: the
+  sweep-controller pod writes to the epoch it receives verbatim in
+  `AIPERF_SWEEP_EPOCH`, while the operator reads
+  `<base>/<ns>/sweeps/<name>/<status.runEpoch>/`. `handlers/sweep/create.
+  _reject_unstorable_epoch` therefore gates the create handler on the same
+  `EPOCH_RE` every downstream directory scan and API route uses, and raises
+  `kopf.PermanentError` before RBAC or the JobSet is created. It is permanent
+  rather than temporary because `creationTimestamp` is immutable — recreate the
+  CR. The rejection lands on `status` (phase `Failed`, `ConfigValid=True`,
+  `Failed` reason `SweepRejected`) plus a `Warning` event, so it is visible to
+  `kubectl get`/`describe` and not only in operator logs.
+
+### Runs/sweep index writes
+
+The operator maintains a SQLite index at `<RESULTS.DIR>/.aiperf_index.sqlite` that mirrors disk state for fast queries. Writes happen at fixed handler points:
+
+```mermaid
+sequenceDiagram
+    participant K as kopf
+    participant O as operator
+    participant FS as PVC
+    participant DB as runs_index
+
+    K->>O: on_create(AIPerfJob)
+    O->>FS: save_job_spec_file
+    O->>DB: upsert_run_created (Pending)
+
+    Note over O: phase transitions (Running, Aggregating, ...)
+    O->>DB: upsert_run_phase
+
+    K->>O: completion observed
+    O->>FS: download results, write ready marker
+    O->>DB: upsert_run_completed + set_latest
+
+    K->>O: on_delete or retention
+    O->>FS: rm -rf run dir
+    O->>DB: delete_run
+```
+
+Read sites (`results_layout.list_runs_async`, `results_db.ResultsDB`, `routers/results_files.py`) consult the index first and fall back to disk only when a row is missing, firing a lazy backfill in the background.
+
+CR deletion wins every race with completion. The delete handler first records a
+sticky cancellation event. The result harvester waits on that event alongside
+metrics requests, primary and sidecar downloads, and retry backoff, so deletion
+interrupts long I/O instead of waiting for its timeout. Metrics and completed
+downloads from earlier boundaries remain available for recovery, but completion
+does not publish terminal status or a latest pointer after cancellation.
+Completion also rechecks cancellation after retention and every index await. If
+cancellation lands while an upsert is in flight, the completion writer deletes
+that exact epoch after the upsert returns; it cannot recreate an orphan row after
+delete cleanup has already passed. Set cancellation flags are never evicted to
+satisfy the progress-client cache bound, including when a large sweep deletes
+thousands of children concurrently.
+
+## 8. Completion & Cleanup
+
+### Lifecycle
+
+```mermaid
+flowchart LR
+    Deploy --> Running --> Complete --> TTL[TTL expires] --> Deleted
+```
+
+### Pending pod reconciliation
+
+The Pod watch classifies each changed Pod body directly and records the
+highest-priority startup blocker in `status.startupIssue` without listing the
+JobSet's Pods. A healthy update for the same Pod clears the blocker. The
+fingerprint and `firstObservedTime` make the grace period survive operator
+restarts. The same diagnostic is exposed through `WorkersReady=False`, and a
+Kubernetes warning event is emitted after
+`AIPERF_K8S_WATCHDOG_PENDING_THRESHOLD_SECONDS`.
+
+A bounded deadline handler re-evaluates only an already-cached
+`status.startupIssue`; it does not list Pods or run the broad recovery engine.
+This lets an unchanged blocker reach its warning or failure threshold even
+when the controller heartbeat remains healthy and no further Pod event occurs.
+Before deleting the JobSet it re-reads and validates the exact parent UID,
+resource version, non-terminal phase, cancellation state, and blocker
+fingerprint. It revalidates again after deletion and commits through an atomic
+UID/resource-version/phase/full-startup-issue JSON fence, so a concurrent
+recovery or terminal transition remains authoritative.
+
+Image pull, container configuration, repeated crash-loop, and structural
+scheduling failures may transition the AIPerfJob to `Failed` only after the
+blocker remains unchanged for
+`AIPERF_K8S_WATCHDOG_PENDING_CRITICAL_THRESHOLD_SECONDS`. Capacity shortages,
+pending PVC binding, unknown scheduler reasons, and Kueue suspension remain
+retryable: they are visible in status but do not auto-fail when the job timeout
+is disabled. The operator checks both regular and init-container statuses and
+`PodScheduled=False` conditions, using its shared `k8s_client` context.
+
+### Lifecycle surface: `status.subPhase`
+
+The controller pushes `status.subPhase` from its `SystemState`
+(`src/aiperf/common/enums/enums.py`) directly to the AIPerfJob at least every
+10 seconds, including quiet states with unchanged progress. It is distinct
+from `status.phase` (the operator's own view) and `status.currentPhase` (the
+per-benchmark stage), and is cleared on terminal transitions.
+
+Focused watches maintain the operator-owned coarse lifecycle while the broad
+recovery engine is gated. JobSet `replicatedJobsStatus` changes update worker
+counts and `WorkersReady`, promoting Pending or Queued jobs to Initializing
+when workers start. Controller `subPhase` transitions promote the job to
+Running at profiling or later states. Event-authored status commits re-read the
+live parent, reject terminal or cancelled jobs, and JSON-patch-test both the
+resource version and expected live phase so a stale JobSet or Pod callback
+cannot reverse a concurrent completion or cancellation. Resource-version or
+JSON-test conflicts raise a bounded Kopf retry; the retried watch handler
+re-reads the parent and rebuilds its status update, so one-shot readiness and
+healthy-Pod clears are not lost to controller heartbeat writes. The subphase
+watch uses this same direct fence and never writes through an ordinary Kopf
+merge patch.
+
+`status.currentPhase` preserves the user-provided phase name, such as
+`cache_prime` or `steady_state_profile`; it is not restricted to the legacy
+`warmup` and `profiling` names. Each `status.phases.<name>` entry includes
+`phaseName`, the closed semantic `phaseKind` (`warmup` or `profiling`),
+`phaseIndex`, and `profilingIndex`. The operator uses `phaseKind` for lifecycle
+behavior: warmup-kind phases remain in Initializing, while a profiling-kind
+phase promotes the job to Running and gates completion regardless of its name.
+For stable `kubectl get` columns, the operator also projects the latest
+profiling-kind phase's counters to top-level `status.requestsCompleted`,
+`status.requestsTotal`, and `status.requestsPerSecond`; printer columns never
+assume a phase is literally named `profiling`.
+
+The controller-side `ProgressRouter` mirrors progress annotations to both the
+JobSet and AIPerfJob and patches the AIPerfJob status. It also refreshes
+the UID-fenced `aiperf.nvidia.com/controller-heartbeat` annotation on every
+push.
+
+`status.currentPhase` is written by that same push
+(`_push_aiperfjob_status` in `src/aiperf/api/routers/progress.py`): it names the
+most recently started phase, mirroring `JobProgress.current_phase`, and prefers
+phases with an explicit identity over legacy aggregate entries. The written
+value is always a key of the `status.phases` map it is pushed with — a phase
+that has started but not yet sent a request is normally omitted from that map,
+so the push emits a zeroed entry for it rather than naming a missing key.
+Consumers such as `_requests_progress_percent` silently fall back to
+alphabetized iteration (which resolves to warmup's 100%) on a miss, so an
+unresolvable pointer is worse than omitting the key entirely.
+
+The status push is fenced against terminal transitions. kopf clears
+`currentPhase` and `subPhase` when it stamps a terminal phase
+(`StatusBuilder.set_phase`), and a push that passed the UID fence just before
+that could otherwise resurrect both keys. When the CR already carries a
+`status.phase`, the push therefore goes out as `application/json-patch+json`
+with a leading `test` op on `/status/phase`, so the apiserver rather than
+wall-clock ordering settles the race. A rejection whose body identifies the
+failed `test` op is logged at debug and dropped — that is the fence working;
+any other rejection is logged at warning with the response body and re-raised,
+so a CRD schema violation in the payload cannot masquerade as a lost race and
+silently stop status updates. A push observing an already-terminal phase is
+skipped outright, payload and all, rather than being trimmed to the non-racy
+keys, so it can never overwrite the completion handler's final `summary`. Only a
+CR with no `status.phase` at all still uses the plain merge patch — there is no
+terminal value to race against yet, and a `test` op on an absent path would
+fail with 422.
+
+`status.serverMetrics` rides on the same push. It is the dashboard's
+non-WebSocket fallback: `job-detail.js` prefers the live per-job socket's
+`serverSummary` and falls back to the CR value when the socket is down, which is
+a common port-forward failure mode. The status subresource has a 1.5 MB
+apiserver object ceiling that neither the WebSocket frame nor the in-memory REST
+cache has, so the CR carries a **curated subset**, not the full export.
+`project_server_metrics_for_cr`
+(`src/aiperf/kubernetes/server_metrics_projection.py`) emits an explicit
+allow-list of the ~20 metric names that
+`src/aiperf/operator/ui/components/server-metrics/helpers.js` (`backendMetric`)
+actually renders, and per series only its `endpoint_url`, `labels`, and the
+`avg`/`max`/`rate`/`p99_estimate`/`count` stats — never raw samples, buckets, or
+timeslices. It is an allow-list rather than a full copy minus excludes so it
+cannot silently regrow as new server metrics are added; adding a metric to
+`backendMetric` requires adding it to `CURATED_METRIC_NAMES` too.
+
+Three limits bound the write. `AIPERF_SERVER_METRICS_CR_PROJECTION_MAX_SERIES`
+and `AIPERF_SERVER_METRICS_CR_PROJECTION_MAX_LABELS` are cardinality sanity
+bounds; overflow drops the offending metric **whole**, with a debug log. Nothing
+is truncated — labels are the series identity, and a trimmed series list or label
+set would decode as a valid-but-wrong aggregate rather than as missing data.
+`MAX_SERIES` is counted per metric across all endpoints, so it must clear the
+worker or GPU count of the largest deployment: a per-worker metric such as
+`dynamo_component_kvstats_gpu_cache_usage_percent` otherwise vanishes whole and
+takes its dashboard tile with it.
+
+`AIPERF_SERVER_METRICS_CR_PROJECTION_MAX_BYTES` is the authoritative backstop,
+because the cardinality caps bound how *many* labels a series carries but not
+how long each label string is. An over-budget projection carries no metrics.
+This matters more than it looks: exceeding the apiserver's 1.5 MB object ceiling
+rejects the whole status patch, `_write_status_patch` re-raises, and
+`_patch_aiperfjob_status` swallows it at debug — so every other status update
+(`phases`, `liveMetrics`, `resultsExported`, `controllerFailure`) stops silently
+too. The projected value is also `scrub_non_finite`-cleaned, because a single NaN
+gauge is an invalid JSON number that would reject the same patch the same way.
+
+Note how the two limits interact before raising either. `MAX_SERIES` is only the
+per-metric bound; the *total* is what `MAX_BYTES` sees. With all 20 allow-listed
+metrics present, the byte budget binds at roughly 85 series per metric — well
+below the 256 default — so on an all-20-metric or many-endpoint deployment
+`MAX_BYTES` is the limit that actually fires. Raising `MAX_SERIES` past that
+point does not buy more data; it hands control to `MAX_BYTES`, whose overflow
+costs the **whole** panel rather than one metric. Raise `MAX_BYTES` alongside it,
+or accept the per-metric drop.
+
+Overflow does **not** omit the key. Omitting it would leave whatever snapshot
+last fit sitting in the CR indefinitely — stale values indistinguishable from
+live ones, which is the failure the snapshot semantic exists to prevent, and one
+the panel cannot self-diagnose (`SummaryStrip` renders only a duration, never an
+absolute `end_time`, so a frozen scrape window looks live). Instead the overflow
+writes `{summary, metrics: {}, projection_dropped: true, projection_message}`,
+which replaces the stale value, and `ServerMetricsSection` renders that flag as
+an explicit "collected but too large to carry" card rather than the "no server
+metrics collected" empty state — an operator who loses the panel should not go
+debug their exporter. It is logged at warning, not debug. `summary` is kept only
+if the marker itself fits, since endpoint URLs are unbounded too.
+
+`status.serverMetrics` is a **snapshot** of the latest scrape, not an
+accumulation. The push's JSON-patch path normally pre-resolves each key through
+`_merge_patch_value` (RFC 7386) so a fenced write stays equivalent to the merge
+patch it stands in for, but that recursively unions dicts — and this key is a
+map of metric name to dict-valued stats, so a metric that stops being projected
+would linger indefinitely with stale values indistinguishable from live ones.
+The caps are a disappearance generator by design, so `serverMetrics` is listed in
+`_SNAPSHOT_STATUS_KEYS` and emitted unresolved, letting the `add` op replace the
+member outright.
+
+Two consequences worth knowing. The CR fallback's per-endpoint details table
+lists fewer source-metric rows than `server_metrics_export.json` does. And a
+backend chip lights only when at least one of that backend's exposed metrics is
+in the allow-list: `detectBackends` scans metric names on whatever payload it is
+given, so any backend whose metrics do not intersect `CURATED_METRIC_NAMES` loses
+its chip on the CR path. KVBM is the guaranteed case — `detectBackends` keys it
+off a `kvbm_*` prefix and no `kvbm_*` metric appears in `backendMetric` — but it
+is a class of gap, not a single instance. The live WebSocket path and the final
+`server_metrics_export.json` are unaffected and keep the full payload.
+
+### Ownership of `status.workers`
+
+`status.workers` is the **controller's** field, not the operator's. The push
+folds the controller's per-pod state cache through
+`build_aggregate_worker_status`
+(`src/aiperf/controller/system_controller_models.py`) and writes all nine
+camelCase keys — `ready`, `total`, `dispatchable`, `routerConnected`,
+`readyRecordProcessors`, `declaredRecordProcessors`, `readyPods`, `totalPods`,
+`degradedPods`. The CRD object declares exactly those nine and carries no
+`x-kubernetes-preserve-unknown-fields`, so the apiserver prunes any other
+spelling; `_build_workers_payload` translates through the operator's
+`WORKER_AGGREGATE_STATUS_CRD_KEYS` alias map so both writers agree on one.
+
+`workers` is listed in `_SNAPSHOT_STATUS_KEYS` alongside `serverMetrics`: it
+mirrors one controller tick rather than accumulating across ticks, so replace
+semantics keep the block internally self-consistent and stop it ever holding
+this tick's `ready` beside an earlier writer's `total`.
+
+The operator still writes the field in the **bootstrap window**. `create.py`
+seeds `{ready: 0, total: <spec workers>}` at admission, and
+`_update_worker_counts` (`src/aiperf/operator/handlers/monitor.py`) refreshes a
+JobSet-derived estimate — `replicatedJobsStatus[name="workers"].ready` scaled by
+`workersPerPod` — until the controller takes over. Both write only `ready` and
+`total`, so **the presence of `totalPods` in the live `status.workers` is the
+takeover marker**, and the operator's write is gated on its absence
+(`_controller_authored_workers`). That marker lives in the CR, so it survives an
+operator restart and needs no extra status field. The controller withholds the
+key entirely until `totalPods > 0`, which both keeps the bootstrap estimate live
+through startup and stops an empty aggregate from overwriting the spec-derived
+`total` with 0.
+
+The two writers must never both be live in steady state: the operator counts
+ready *pods* scaled by a config constant, the controller counts workers that
+actually registered with the credit router. They disagree during rollout and
+after partial worker failure, and `status.workers.ready` would flap between them
+depending on which patched last. The CRD's own wording settles the tie — the
+field is "Controller-authored aggregate worker status" and `ready` is a
+"Dispatch-ready worker count", which a scaled ready-pod count is only an upper
+bound on.
+
+Because the operator's estimate is only ever the bootstrap value, the accuracy
+of the `workersPerPod` derivation still matters: it is what `aiperf kube list`
+and the `WorkersReady` condition read before the first controller tick lands.
+That derivation must mirror the deployment-side one in
+`src/aiperf/kubernetes/jobset.py` (fall back to
+`Environment.WORKER.DEFAULT_WORKERS_PER_POD`, reproduce the single-pod collapse
+when the total is not divisible) rather than reading the un-normalized CR spec.
+
+The `WorkersReady` condition follows ownership rather than the writer. Once the
+controller owns the field, `_set_workers_ready_condition` asserts the condition
+from the controller-authored `ready`; before that it uses the JobSet estimate.
+Nothing else sets `WorkersReady` true, so it must never be left without a
+setter: the completion backfill would otherwise always fire and assert "Job
+completed before workers (N) were observed ready" with N > 0.
+
+The operator's recurring watchdog inspects only this cached parent body while
+the heartbeat is fresh; broad JobSet, Pod, sidecar, and results recovery
+runs only after heartbeat expiry or when an explicit `timeoutSeconds` deadline
+is due. A controller service error is pushed as `status.controllerFailure`
+before that controller exits; the operator fences and terminalizes the exact
+parent as Failed, and never lets a later sidecar artifact salvage reinterpret
+that explicit failure as a successful completion.
+
+One transition is easy to misread: `SystemState.PROCESSING` is set when the
+SystemController handles `CreditsCompleteMessage` — that is, when request
+*dispatch* finishes and only record aggregation remains. It is **not** set at
+profile completion; the whole aggregation phase happens while `subPhase` reads
+`processing`.
+
+For the same reason, the job-timeout drain guard in `_check_job_timeout` keys off
+`status.resultsExported` — pushed by the controller only once every exporter has
+flushed — and never off `status.currentPhase`. `currentPhase` is a pointer into
+`status.phases` and carries user-supplied phase names, so a benchmark phase named
+`processing` would otherwise bypass the timeout. A timed-out run is deferred to
+the completion handler only when the completion claim is already held or
+`resultsExported` is true; a run whose aggregation or export hangs still fails on
+the deadline.
+
+### Completion Signals
+
+- Controller receives `ALL_RECORDS_RECEIVED` message
+- Results available via API service
+- Services shut down cleanly
+
+For `exportLevel: raw`, result publication has an additional acknowledged
+barrier before shutdown. While ZMQ and the group-local lifecycle channels are
+still live, `SystemController` sends `FINALIZE_ARTIFACTS` to the exact set of
+registered `WorkerGroupManager` service IDs. Each manager requires its exact
+declared record-processor set to flush successfully, stops those processors,
+waits for their exact shutdown notices, and uploads every materialized RAW
+JSONL file. The controller API stages each upload under a temporary name,
+fsyncs it, and atomically renames it before returning the size acknowledgement.
+Only then does the manager acknowledge the controller command.
+
+A rejected RAW row, timeout, flush error, HTTP failure, or size mismatch fails
+the barrier: the controller withholds both the results-ready marker and
+`ResultsExportedMessage`, so an incomplete RAW result set cannot be advertised
+as authoritative. Missing worker-group managers are judged against the same
+pod-loss tolerance the rest of the run uses
+(`_raw_finalize_membership_is_acceptable` vs.
+`AIPERF_POD_FAILURE_ABORT_THRESHOLD_PERCENT`): inside the threshold the barrier
+proceeds against the managers that are still registered and records a
+`DegradedRawArtifactSet` exit error, so the run keeps its results but exits
+non-zero; outside the threshold — or with no manager left to ask — it fails
+closed as above. Empty processors are valid and may produce no file; completion
+is proven by service acknowledgements rather than filename counts or file-size
+stability polling.
+
+The controller performs final export before broadcasting service shutdown or
+stopping its message bus. After the durable marker commits, the still-running
+API service can therefore receive `ResultsExportedMessage`; the marker remains
+the authoritative recovery signal if that live notification is lost.

+### CLI Options
+
+```bash
+aiperf kube profile \
+  --image myregistry.io/aiperf:latest \
+  --namespace benchmarks \
+  --total-workers 10 \
+  --ttl-seconds 300 \
+  --kubeconfig ~/.kube/prod-config \
+  --node-selector '{"nvidia.com/gpu": "A100"}' \
+  --tolerations '[{"key":"nvidia.com/gpu","operator":"Exists"}]' \
+  --image-pull-secrets registry-creds \
+  --env-from-secrets.OPENAI_API_KEY llm-api-key/api-key
+```
+
+`--env-from-secrets` is a mapping flag. All three spellings are equivalent:
+dot-notation (`--env-from-secrets.KEY value`), `KEY=VALUE`
+(`--env-from-secrets KEY=value`), and a JSON object
+(`--env-from-secrets '{"KEY": "value"}'`). The same applies to `--annotations`,
+`--labels`, and `--env-vars`.
+
+Only dot-notation is native to cyclopts. A bare token on a mapping-typed field
+reaches `Argument._json` with an empty `keys` tuple and raises
+`IndexError: tuple index out of range` — an upstream defect present in both
+cyclopts 4.23.2 and 5.0.0b1. `normalize_mapping_flag_tokens`
+(`src/aiperf/cli_commands/kube/_mapping_flags.py`) is registered as the `kube`
+app's cyclopts `config` callable, which runs after token parsing and before
+conversion. It re-keys bare `KEY=VALUE` and JSON-object tokens into the keyed
+tokens cyclopts expects, and raises a usage error naming every accepted
+spelling for anything else. Adding a new mapping-typed CLI field anywhere under
+`aiperf kube` is covered automatically; pair it with `n_tokens=-1` so repeating
+the flag accumulates entries instead of raising `RepeatArgumentError`.
+
+Sensitive endpoint fields never rely on the ConfigMap copy. JSON
+serialization redacts them, and `aiperf service --benchmark-run` restores them
+from the Secret-backed `AIPERF_INJECTED_API_KEY`/`OPENAI_API_KEY`,
+`AIPERF_INJECTED_HEADERS`, and `AIPERF_INJECTED_ENDPOINT_URLS` environment
+variables. Generation and operator reconciliation fail closed when the
+corresponding `valueFrom.secretKeyRef` mapping is absent.
+`aiperf service` requires `--benchmark-run` and never resolves per-container
+benchmark flags.
+
+Anything the pre-bootstrap resolver chain would normally produce must therefore
+either travel inside the serialized run or be rendered from it.
+`artifacts.user_files` works this way: the declared entries ride along in
+`run_config.json`, and `aiperf.kubernetes.user_files.materialize_serialized_run_user_files`
+renders them once, in the `system_controller` container, before the benchmark
+starts. Because the pod's `artifacts.dir` is the fixed `/results` mount and
+carries neither the run epoch nor the AIPerfJob name, `handlers/create.py`
+freezes a `RunMeta` (epoch key, job name, namespace) into the serialized run for
+the template context; locally that field stays `None` and `ArtifactDirResolver`
+derives it from the resolved artifact dir. See
+[`docs/kubernetes/user-files.md`](../kubernetes/user-files.md).

+### AIPerfSweep handlers
+
+The kopf operator registers sweep-lifecycle handlers in `src/aiperf/operator/main.py`. Seven registrations are on the parent `AIPerfSweep` CRD; one more watches child `AIPerfJob`s to roll their status up into the parent:
+
+- `@kopf.on.create AIPerfSweep` (handler in `handlers/sweep/create.py`) — validates the workload through the canonical Config-v2 mapping loader and `AIPerfSweepSpec`, computes `totalVariations`/`maxTotalRuns`, sets `status.runEpoch` to a collision-safe decimal key derived from `metadata.creationTimestamp` and immutable `metadata.uid` (rejecting the CR outright if that key is not `EPOCH_RE`-storable — see "Edge cases" above), provisions a namespace-scoped ServiceAccount/Role/RoleBinding for the sweep-controller pod, and creates a single-replica JobSet that runs `python -m aiperf.sweep_controller.main`. The sweep-controller pod's two containers honour `spec.resourceMode`, including its unset `burstable` default; the resolved value is read off the validated `AIPerfSweepSpec` rather than the handler's `exclude_unset=True` dump, which omits unset fields.
+- `@kopf.on.update AIPerfSweep field=spec.cancel` (handler in `handlers/sweep/lifecycle.py`) — mirrors the cancel signal into `status.conditions[Cancelling]` and advances `status.observedGeneration`, including terminal/no-op updates, so GitOps clients can distinguish an acknowledged spec change. The sweep-controller pod observes `spec.cancel` directly via its own poll and propagates it to the current child.
+- `@kopf.on.update AIPerfSweep field=spec.ttlSecondsAfterFinished` — acknowledges the other mutable parent control immediately. The reaper timer reads the latest TTL; create-time execution fields are immutable after admission.
+- `@kopf.on.field AIPerfSweep field=status.aggregation.phase new=Complete` plus `@kopf.on.resume` — triggers `handlers/sweep/_aggregate_fetch.fetch_sweep_aggregate_to_disk` to pull the cross-variation aggregate off the sweep-controller's `emptyDir` results-sidecar before the JobSet is reaped, and resumes an interrupted harvest after an operator restart. The fetch reports `(downloaded, listed)` counts; a partial harvest (`downloaded < listed`) or a missing/unparsable `aggregate.json` raises `kopf.TemporaryError` so the JobSet — and with it the only other copy of the artifacts — stays alive for re-harvest. During commit, the operator materializes every child `sweep.json` backlink on its PVC from the canonical `children.json` manifest before status publication. Delayed callbacks carry the parent CR's immutable UID, verify the live parent and exact JobSet owner API version/kind/name/UID with `controller: true`, and publish status with a JSON Patch UID test before advancing `latest.txt` or the runs index. Only a full harvest with a parseable `aggregate.json` and durable child lineage on the PVC publishes the operator-backed `aggregateRef`, flips `resultsAvailable` to true, and deletes that exact JobSet with its resource UID as a delete precondition. A same-name replacement makes the old callback a no-op; transient reads and status-validation failures against the current owner retry.
+- `@kopf.on.delete AIPerfSweep` — cooperatively cancels only AIPerfJobs whose exact owner kind/name/UID matches the deleting sweep; sweep labels narrow discovery but never establish ownership. Kubernetes owner-reference GC tears down the sweep-controller JobSet and RBAC.
+- `@kopf.timer` `cleanup_old_sweeps` — TTL reaper for terminal `AIPerfSweep`s, evaluated at the operator monitor cadence rather than the daily result-retention cadence. A completed aggregate is not eligible until the operator-backed result reference is published, so even `ttlSecondsAfterFinished: 0` cannot delete the only `emptyDir` copy during harvest. Parent deletion uses the timer body's immutable UID as a Kubernetes delete precondition, so a stale timer cannot reap a same-name replacement.
+- `@kopf.on.field AIPerfJob field=status.phase` (handler in `handlers/sweep/child_rollup.py`) — this one is on **child AIPerfJobs**, not the AIPerfSweep CRD: for AIPerfJob children whose `ownerReferences` include an `AIPerfSweep`, it recomputes the parent's `runStates`/`currentChildRef`/`lastChildEvent`. The rollup step is a no-op for a standalone AIPerfJob, but the same registration always also mirrors the new phase into the runs index (`handlers/lifecycle.record_phase_transition`).
+
+Sweep **result** retention is process-level rather than a CR timer. After the
+runs-index bootstrap and once per day, the operator scans durable sweep epoch
+directories, reads `aggregate.json.specSnapshot.resultsTtlDays` (falling back
+to `AIPERF_RESULTS_TTL_DAYS` for legacy archives), removes expired archives
+and SQLite rows, and reconciles `latest.txt`. This continues after the parent
+CR's default 300-second lifecycle TTL has elapsed; bootstrap reverse-pruning
+repairs an index delete interrupted by an operator crash.
+
+The AIPerfJob CRD likewise permits only runtime-control edits after creation:
+`spec.cancel` and `spec.timeoutSeconds`. Their dedicated field handlers advance
+`status.observedGeneration` only after the edit is consumed successfully; a
+failed JobSet deletion leaves a cancel edit unacknowledged for kopf to retry.
+
+### Sweep plan convergence
+
+Kubernetes and local sweeps use the same Config-v2 planning path. The kube CLI
+keeps the post-environment, pre-Jinja template leaves in the submitted CR. The
+operator and sweep-controller validate a rendered copy through
+`load_config_from_mapping`, while retaining that raw envelope so each variation
+can render its own values. The sweep-controller then calls
+`build_benchmark_plan` from `build_plan_from_sweep`
+(`src/aiperf/sweep_controller/plan_builder.py`), whose only plan adaptations are
+attaching the Kubernetes-only `failurePolicy` and, for an unseeded stochastic
+sweep (Sobol, Latin hypercube, adaptive search), deriving a seed from the CR's
+immutable `metadata.uid` so variations stay stable across sweep-controller pod
+restarts. Adaptive sweeps instantiate their planner through the shared
+`build_search_planner` factory, and
+`K8sChildJobExecutor` supplies the cluster execution backend behind the same
+`RunExecutor` protocol used by local sweeps.
+
+## CRD Generator
+
+Both CRDs (`aiperfjobs.aiperf.nvidia.com`, `aiperfsweeps.aiperf.nvidia.com`)
+are auto-generated by `tools/generate_crd.py` from the `AIPerfJobSpec` and
+`AIPerfSweepSpec` Pydantic models (`src/aiperf/kubernetes/crd_models.py`).
+Both inherit `AIPerfWorkloadSpec`, which composes the complete `AIPerfConfig`
+envelope (`benchmark`, `sweep`, `multiRun`, `variables`, and related fields)
+with the Kubernetes deployment surface. **Never edit the rendered YAML in
+`deploy/helm/aiperf-operator/templates/crd*.yaml` directly** — the next
+regeneration overwrites it.
+
+### Generator pipeline
+
+1. **JSON Schema walk** (`_convert_schema`) — recursively converts the
+   Pydantic-emitted JSON Schema into K8s-compatible OpenAPI v3, resolving
+   `$ref`, collapsing `anyOf`-with-null into nullables, and falling back to
+   `x-kubernetes-preserve-unknown-fields: true` at narrow shorthand
+   boundaries (`models`, `endpoint.urls`, top-level
+   `model`/`dataset`/`warmup`/`profiling`, `sweep`).
+2. **Type-on-marker pass** (`_ensure_type_on_preserve_unknown`) — defaults
+   `type: object` on every node carrying `x-kubernetes-preserve-unknown-fields:
+   true`. K8s structural-schema validation rejects the marker without a
+   declared type, AND CEL field access compiles only on typed nodes.
+3. **Shape-detector decorators** (`_decorate_*_node`) — each helper detects
+   its target node by a unique fingerprint of property keys (e.g. an
+   endpoint node has `urls` + `apiKey` + `connectionReuse`; a runtime node
+   has `apiPort` + `apiHost` + `workersPerPod`). The walker
+   (`_walk_dict_apply`) calls every decorator on every dict node, so the
+   same set of CEL rules fires on both AIPerfJob's `spec.benchmark` and
+   AIPerfSweep's `spec.benchmark` from a single pass.
+4. **Kind-specific attachment** — after the walker runs, each builder attaches
+   its own rules to the top-level spec node: `has(self.sweep)` makes the sweep
+   block required in `_build_aiperfsweep_crd_from_schema`, and the inverse
+   `!has(self.sweep)` fires on AIPerfJob. `_tighten_sweep_schema` reaches into
+   the `sweep` property directly to pin its `type` enum and `parameters` shape.
+   Both builders then call `_apply_workload_spec_immutability`, which emits a
+   presence-safe `has(oldSelf.X) == has(self.X) && (!has(self.X) || oldSelf.X ==
+   self.X)` transition rule for *every* top-level spec field except that kind's
+   mutable set — `{cancel, timeoutSeconds}` for AIPerfJob and
+   `{cancel, ttlSecondsAfterFinished}` for AIPerfSweep. The old Tier-1D rule that
+   forbade `sweep`/`multi_run` inside the per-child benchmark was removed —
+   `AIPerfJobSpec.benchmark` is typed as `BenchmarkConfig` (no such fields), so
+   the generated structural schema enforces it at the apiserver without CEL.
+
+### Adding a CEL rule
+
+The user-facing catalog of every rule lives in
+[`docs/kubernetes/crd-validation.md`](../kubernetes/crd-validation.md). To
+add a new one:
+
+1. Identify the **shape** the rule applies to (benchmark, endpoint,
+   runtime, multiRun) and pick the matching `_decorate_*_node`
+   helper. If your target is a brand new shape, write a new shape detector
+   modelled on the existing ones.
+2. Append a `{"rule": ..., "message": ...}` entry to that helper's
+   `_add_validation_rules(...)` call. Tag the rule with the tier label
+   (1A/1B/.../4O) in a comment so future-you can grep back to the
+   brainstorm in `docs/kubernetes/crd-validation.md`.
+3. Add a structural assertion in
+   `tests/unit/operator/test_aiperfsweep_crd_generation.py` (the existing
+   tests follow a "rule string is in `rules` set" pattern).
+4. Regenerate with `uv run python tools/generate_crd.py` and confirm
+   idempotency with `tools/generate_crd.py --check`.
+5. Round-trip on a real apiserver (`kind create cluster && kubectl apply
+   --dry-run=server -f crd.yaml`). The K8s apiserver compiles CEL at
+   CRD-install time and rejects rules that reference undeclared fields
+   (`undefined field 'X'`) or opaque preserve-unknown items.
+
+CEL constraints worth remembering:
+
+- `has(self.X)` requires X to be declared in the schema. Anything hidden
+  inside a `x-kubernetes-preserve-unknown-fields: true` blob is invisible.
+- Array items emitted as opaque preserve-unknown blobs cannot be
+  dereferenced. Heterogeneous Pydantic discriminated unions
+  (`phases[]`, `datasets[]`) end up opaque, so item-internal invariants
+  (phase-name uniqueness, phase→dataset compatibility, "seamless not
+  on first") stay enforced by the shared `@model_validator` decorators in
+  `src/aiperf/config/config.py`, which the operator re-runs when it validates
+  the spec, rather than at the apiserver.
+- `oldSelf` is only available in transition rules and triggers on
+  `kubectl edit` / `kubectl patch`. Kubernetes does not evaluate a
+  *field-scoped* transition rule when an optional field is added or removed, so
+  immutability rules go on the parent spec node in the
+  `has(oldSelf.X) == has(self.X) && (!has(self.X) || oldSelf.X == self.X)` form
+  (`_immutable_spec_field_rule`). The `has` parity is what rejects
+  first-set-after-create and removal as well as value changes.
+
+## Fail-Closed Semantics Are Kubernetes-Only
+
+Kubernetes needs strictness that a local `aiperf profile` run does not. A pod
+that dies silently must surface, and a nonzero exit is how the operator marks
+the CR failed. The same semantics applied to a local run turn correct, complete
+benchmarks into failures, so each one is gated on an explicit runtime
+predicate:
+
+| Behavior | Kubernetes | Local (`MULTIPROCESSING`) | Gate |
+|---|---|---|---|
+| Heartbeat-stale service | Reaped and failed — heartbeats are the only liveness signal available | Never reaped while its `multiprocessing.Process` is alive | `BaseServiceManager.get_service_liveness` returns `None` in Kubernetes, the real `Process.is_alive()` locally |
+| Stale **optional** service (GPU telemetry, server metrics) | Unregistered with a warning | Unregistered with a warning | `service_type not in required_services` — same on both paths, matching `_reap_dead_processes_during_registration` |
+| Advisory `PROCESS_RECORDS_RESULT` errors | Appended to `_exit_errors`, so the run exits 1 | Logged at ERROR only | `SystemController._is_kubernetes()` |
+| A record artifact writer that failed to finalize | Raises `ExceptionGroup`, failing the run closed | Logged at ERROR; the healthy writers still finalize | `RecordProcessor._is_group_managed_mode()` |
+
+The local relaxations never weaken the cluster path, and they never degrade
+diagnostics: every condition above is still logged, only the verdict changes.
+A genuinely crashed local child still reports `is_alive() is False` and is
+still reaped, which remains strictly stronger than having no watchdog at all.
+
+## Key Architecture Decisions
+
+| Decision | Rationale |
+|----------|-----------|
+| **JobSet API** | Orchestrates controller + workers as atomic unit |
+| **Dual-bind ZMQ** | IPC for in-pod speed, TCP for cross-pod reach |
+| **API-based results** | Retrievable via API service or kubectl cp |
+| **Dataset HTTP API** | Avoids shared volume complexity |
+| **WebSocket streaming** | Real-time progress to local CLI |
+| **Container-per-service** | One container per service; failure isolation and per-container resources |

+## Control Channel Command Pattern
+
+Commands do **not** ride the pub/sub event bus. They ride a dedicated
+DEALER/ROUTER control channel at `CommAddress.CONTROL`: every component service
+opens a DEALER (identity = its service ID), and `SystemController` binds the
+single ROUTER. The wire format is the `msgspec` tagged-union structs in
+`aiperf.common.control_structs`, not Pydantic `Message` subclasses. The same
+channel also carries registration (`Registration` / `RegistrationAck`),
+`Heartbeat`, and `StatusUpdate`.
+
+Every other message type still goes over the event bus with `publish()` /
+`@on_message`.
+
+### Request/response structs
+
+| Struct | Meaning |
+|---|---|
+| `Command{cid, cmd, payload}` | The request. `cid` correlates the response; `payload` is `orjson`-encoded bytes (`b""` when the command carries no data). |
+| `CommandAck{cid, cmd, sid}` | Handler ran and returned `None`. |
+| `CommandOk{cid, cmd, sid, payload}` | Handler returned a value, serialized into `payload`. |
+| `CommandErr{cid, cmd, sid, error, traceback}` | Handler raised. |
+| `CommandUnhandled{cid, cmd, sid}` | No `@on_command` hook matched. |
+
+`CommandUnhandled` is deliberately not an ack: "no handler" is a *failure* to
+callers that need the work done. `SystemController._finalize_artifact_response_error`
+treats it as one. Do not assume an unhandled command is harmless.
+
+### Adding a new command
+
+1. Add the value to `CommandType` in `common/enums/enums.py`.
+2. Add a handler on the receiving service. It takes a single `Command`:
+
+```python
+from aiperf.common.control_structs import Command
+from aiperf.common.hooks import on_command
+
+@on_command(CommandType.MY_COMMAND)
+async def _on_my_command(self, message: Command) -> None:
+    # Decode the payload only if the command carries data.
+    opts = orjson.loads(message.payload) if message.payload else {}
+    await self._do_the_thing(opts.get("mode"))
+```
+
+Returning `None` makes the dispatcher send `CommandAck`. Returning a value makes
+it send `CommandOk` with the value serialized into `payload` (`bytes` pass
+through, Pydantic models use `model_dump_json()`, everything else goes through
+`orjson.dumps`).
+
+Exactly **one** hook may claim a given `CommandType` per service — the dispatcher
+stops at the first match, because the response it sends back is that hook's
+result and a second hook would have no way to answer.
+
+### Sending a command
+
+From a service to the controller:
+
+```python
+response = await self.send_command_to_controller(
+    CommandType.MY_COMMAND, payload=orjson.dumps({"mode": "fast"})
+)
+```
+
+From the controller to services:
+
+| Method | Behavior |
+|---|---|
+| `_send_control_command(identity, cmd, ...)` | One service, awaits its response. |
+| `_send_control_command_to_all(cmd, service_ids, ...)` | Fan-out, returns responses in **input order** so callers can `zip(service_ids, responses, strict=True)`. Failures become `ErrorDetails` entries rather than raising. |
+| `_send_control_command_to_all_fail_fast(cmd, service_ids, ...)` | Completion-ordered fan-out that stops waiting on the first `CommandErr` or timeout. `CommandUnhandled` is **not** an abort condition here — the two callers fan `PROFILE_CONFIGURE` / `PROFILE_START` at every registered service and several legitimately implement neither. |
+| `_broadcast_control_command(cmd, service_ids, ...)` | Fire-and-forget; per-peer send errors are swallowed so one dead service cannot block the rest. |
+
+### Peer-to-peer commands must be relayed
+
+The ROUTER is the only path between two non-controller services — services have
+no socket to each other. A command aimed at a *peer* therefore needs a
+controller-side handler that re-fans it out. `PROFILE_COMPLETE` and
+`PROFILE_CANCEL` both work this way: the originating service sends to the
+controller, and the controller's handler broadcasts to the other services,
+excluding the originator.

+## Machine-Readable Kube CLI Output Pattern
+
+Any `aiperf kube` command with a JSON or YAML output mode writes the payload
+through `kube_console.emit_raw`, never `kube_console.console.print`. Rich
+hard-wraps lines wider than the resolved console width — 80 whenever stdout is
+not a tty — and the wrap lands inside the token, so a long image reference or
+endpoint URL turns a valid document into an unparseable one under redirection
+or in CI. `soft_wrap=True` also avoids the wrap, but it is per-call discipline
+that is easy to forget; `emit_raw` makes the correct path the only path.
+
+```python
+from aiperf.kubernetes import console as kube_console
+
+kube_console.emit_raw(orjson.dumps(payload, option=orjson.OPT_INDENT_2).decode())
+kube_console.emit_raw(yaml.safe_dump(doc, width=float("inf")), end="")  # already \n-terminated
+```
+
+Wrap the work that produces the payload in `machine_readable_stdout()` when it
+can log. The context manager retargets the `aiperf.kube` handlers to stderr for
+the duration instead of filtering by level, so a record emitted at *any* level
+— including one added by a later change — cannot prepend text to the document
+on stdout. Diagnostics stay visible, just on the other stream.
+
+```python
+with kube_console.machine_readable_stdout():
+    results = await checker.run_all_checks()
+kube_console.emit_raw(orjson.dumps(results.to_dict()).decode())
+```
+
+Human-facing log text (`aiperf kube logs`, controller log streaming) keeps
+going through `console.print`, but with `soft_wrap=True`: those lines may want
+styling later, and letting the terminal fold a long URL beats breaking it
+mid-token.

No orchestrator changes required — `MonotonicSLASearchPlanner`, `SmoothIsotonicSLAPlanner`, and `OptunaSearchPlanner` are existing examples reusing the same ABC. Wiring is already generic: `AdaptiveSearchSweep.planner` is a `SearchPlannerType` (`ExtensibleStrEnum` in `src/aiperf/plugin/enums.pyi`), and `cli_runner._run_multi_benchmark` instantiates the planner via `plugins.get_class(PluginType.SEARCH_PLANNER, sweep.planner)`. To register a new backend, add an entry under `search_planner:` in `src/aiperf/plugin/plugins.yaml` and a matching enum value — no dispatch code changes.

 - **Replacing the BO backend.** The `OptunaSearchPlanner` boundary (and its `BayesianSearchPlanner` curated-preset subclass) is the only Optuna-aware code in the project. BoTorch-specific acquisitions live behind the optional `botorch` extra in `pyproject.toml`. The `qlognei` / `qlognehvi` acquisitions, posterior-regret stopping (`--optuna-terminator regret`/`emmr`), pooled-percentile aggregation (`--search-percentile-pooling pooled`), and the Hvarfner-DSP Matern-5/2 kernel ([arXiv:2402.02229](https://arxiv.org/abs/2402.02229)) are all plumbed through `_optuna_helpers.py`. The remaining principled upgrade path is wiring per-iteration heteroscedastic noise estimates from the pooled-percentile JSONL helper into a `HeteroskedasticSingleTaskGP`-based custom `candidates_func`. Evidence-gated: ship only if observed within-trial variance varies meaningfully across the search space on real workloads.

The annotation lives on CR metadata, which any AIPerfJob editor can write, so trusting it without bound would let a forged or orphaned value disable terminal-phase enforcement forever. Deliberately NOT derived from ``spec.timeoutSeconds``: the window has to cover post-benchmark result draining (fetch + retries + retention), which is unrelated to — and routinely longer than — a short benchmark deadline, and a claim is only ever stamped after completion evidence.

Reads afterwards are served warm, so no request pays a major page fault mid-benchmark -- which would otherwise land in the measured latency. Workers share the kernel page cache, so the disk read happens once regardless of worker count. Costs a one-time startup pass proportional to dataset size; set to False to trade predictable tail latency for faster startup on very large datasets. |

This is a throughput optimization that DROPS input-tokenization metrics (input_sequence_length, image counts) because the structured prompt is discarded. Default False keeps the structured-turns (CONVERSATION) path so those metrics are computed. Datasets that natively ship raw payloads (raw_payload / inputs_json / mooncake-with-payload) always use PAYLOAD_BYTES regardless of this flag; cache-bust runs always use CONVERSATION regardless. |

Enables cross-container `kubectl exec kill -9 <pid>` for chaos-testing workflows. Keep false in production; chaos fixtures flip it on via AIPERF_K8S_SHARE_PROCESS_NAMESPACE=true. |
+| `AIPERF_K8S_CONTROLLER_HTTP_URL_OVERRIDE` | `None` | — | Chaos-test hook: when set, the operator's progress-client uses this base URL (scheme+host+port, e.g. http://toxiproxy.aiperf-chaos-toxiproxy.svc:20002) instead of the per-CR JobSet pod DNS + API_SERVICE port for controller HTTP calls. Production MUST leave unset — it collapses multi-job isolation because every CR funnels through the same URL. Chaos fixtures set it via AIPERF_K8S_CONTROLLER_HTTP_URL_OVERRIDE to steer traffic through toxiproxy for latency/blackhole injection. |
+| `AIPERF_K8S_APISERVER_TLS_SERVER_NAME_OVERRIDE` | `None` | — | Chaos-test hook: when KUBERNETES_SERVICE_HOST points at an L4 proxy rather than kubernetes.default.svc, verify the apiserver certificate against this hostname while still dialing the proxy. Production MUST leave unset; C15 sets it to kubernetes.default.svc. |
+| `AIPERF_K8S_RESULTS_SIDECAR_LOG_LEVEL` | `'info'` | one of: 'critical' / 'error' / 'warning' / 'info' / 'debug' / 'trace' | Uvicorn log level injected into controller results sidecars. |

+## K8SDIAGNOSIS
+
+Thresholds for ``aiperf.kubernetes.benchmark_diagnosis`` heuristics.

+|----------------------|---------|-------------|-------------|

Defaults to 1.0, so only a run in which every single request errored is failed outright; a run that merely errored heavily still completes and is flagged by the high-error-rate diagnosis. Lower it to enforce a stricter success bar. |

+
+## K8SJOBSET
+
+JobSet-level configuration.
+
+| Environment Variable | Default | Constraints | Description |
+|----------------------|---------|-------------|-------------|
+| `AIPERF_K8S_JOBSET_TTL_SECONDS_AFTER_FINISHED` | `300` | ≥ 0 | Seconds to keep JobSet after completion (None to disable) |
+| `AIPERF_K8S_JOBSET_DIRECT_MODE_TTL_SECONDS` | `28800` | ≥ 0 | TTL for operator-less (direct) deployments. Pods stay alive for manual results retrieval. Default 8 hours (28800s). |
+| `AIPERF_K8S_JOBSET_CONTROLLER_BACKOFF_LIMIT` | `0` | ≥ 0, ≤ 10 | Job backoff limit for controller (0 = no retries) |
+| `AIPERF_K8S_JOBSET_WORKER_BACKOFF_LIMIT` | `20` | ≥ 0, ≤ 20 | Job backoff limit for workers (allows retries for transient failures) |
+| `AIPERF_K8S_JOBSET_WORKER_CONNECTION_PROBE_TIMEOUT` | `60.0` | ≥ 30.0, ≤ 600.0 | Seconds worker pods wait for the PUB/SUB connection probe to succeed. Overrides AIPERF_SERVICE_CONNECTION_PROBE_TIMEOUT for k8s worker containers only. Pods that cannot connect exit cleanly so Kubernetes restarts them with a fresh ZMQ context; WORKER_BACKOFF_LIMIT absorbs transient first-deploy flakes. |
+| `AIPERF_K8S_JOBSET_PATCH_INTERVAL` | `10.0` | ≥ 0.1, ≤ 600.0 | Interval in seconds between controller patches of JobSet progress annotations |
+| `AIPERF_K8S_JOBSET_CONFIG_MOUNT_PATH` | `'/etc/aiperf'` | — | Path to mount ConfigMap with configs |

+| `AIPERF_K8S_JOBSET_SWEEP_AGGREGATE_INLINE_MAX_BYTES` | `600000` | ≥ 10000, ≤ 900000 | Max encoded size of the AIPerfSweep aggregate bundle inlined into status.aggregate. K8s rejects CR patches over ~1 MiB with HTTP 413; if the bundle exceeds this cap, the sweep-controller drops `confidence` (the largest contributor on big sweeps) and relies on the disk-backed results sidecar to serve the full document. Default 600 KB leaves headroom for status fields and apiserver framing under the 1 MiB ceiling. |
+| `AIPERF_K8S_JOBSET_KUEUE_DEFAULT_QUEUE_NAME` | `''` | — | Operator-side default for Kueue gang-scheduling. When the AIPerfJob CR's spec.scheduling.queue_name is unset, the JobSet manifest falls back to this value. When non-empty, the JobSet gets the kueue.x-k8s.io/queue-name label, which Kueue's JobSet integration uses to admit the workload as a unit (gang-scheduling: controller + all worker pods admitted atomically, or none). Safe to leave unset on clusters without Kueue — the label is then never added. Set to e.g. 'aiperf-lq' on clusters where Kueue is installed and a LocalQueue of that name exists in the benchmark namespace. |
+| `AIPERF_K8S_JOBSET_KUEUE_DEFAULT_PRIORITY_CLASS` | `''` | — | Operator-side default for Kueue WorkloadPriorityClass. Companion to KUEUE_DEFAULT_QUEUE_NAME. When unset, the JobSet gets no kueue.x-k8s.io/priority-class label and Kueue's default fairness applies. |

+## OPERATOR
+
+Kubernetes operator identity and namespace-ownership configuration. Read by the kopf operator process and by ``aiperf kube`` when it reports which operator owns a namespace. The ``AIPERF_OPERATOR_`` prefix is shared with ``aiperf.operator.environment.OperatorEnvironment``, which holds the settings only the operator process reads. A new ``AIPERF_OPERATOR_*`` variable belongs here only if non-operator code (the CLI, a benchmark pod) also reads it; check both files before adding one, so the two do not collide on a name.
+
+| Environment Variable | Default | Constraints | Description |
+|----------------------|---------|-------------|-------------|
+| `AIPERF_OPERATOR_ID` | `''` | — | Operator identity used to claim namespaces via a coordination.k8s.io Lease named 'aiperf-operator'. Empty (the default) means this is the cluster-wide global operator: it writes no Lease and reconciles every namespace no scoped operator has claimed. Set a unique id to run a scoped operator alongside the global one. |

Deliberately long so a crash-looping scoped operator keeps its namespaces across restarts; only an uninstall lets the claim lapse to the global operator. |
+
+## OPERATOR
+
+Operator-service network identity. The operator Pod has three containers but only ONE FastAPI app: the ``results-server`` sidecar on ``resultsServer.port`` (8081 in the chart) hosts every ``/api/v1/*`` router (jobs, sweeps, results, config, admin, analytics, dashboard_proxy). The ``operator`` container on port 8080 runs kopf only — its sole HTTP surface there is ``/healthz``, with Prometheus ``/metrics`` on a separate server bound to ``METRICS_PORT`` (9090 in the chart). So there is no separate "sweeps API URL" and "results API URL" — one base URL, pointing at the results-server. Used when the operator stamps absolute URLs onto CR status (e.g. ``AIPerfSweep.status.apiUrl``, ``AIPerfSweep.status.runsTruncated.fetchURL``) that external clients dereference to fetch results, and when in-pod consumers (e.g. the sweep-controller's empty-summary fallback) need the operator's API endpoint.

+| Environment Variable | Default | Constraints | Description |
+|----------------------|---------|-------------|-------------|
+| `AIPERF_OPERATOR_BASE_URL` | `f'http://aiperf-operator.{DEFAULT_OPERATOR_NAMESPACE}:8081'` | — | Base URL (no trailing slash) for the operator's HTTP API. All ``/api/v1/*`` routers — jobs, sweeps, results, config, admin, analytics, dashboard_proxy — are served by the ``results-server`` container on this port; the operator container exposes only ``/healthz`` + ``/metrics`` on port 8080. Stamped onto ``AIPerfSweep.status.apiUrl`` and ``AIPerfSweep.status.runsTruncated.fetchURL`` so external clients can fetch per-sweep summaries; also consumed by the sweep-controller's per-child summary fallback. Override via ``AIPERF_OPERATOR_BASE_URL`` when the operator's Service+Namespace differ from the Helm chart defaults (e.g. a non-default ``Release.Name`` or an alternate namespace). |

None (default) auto-detects: bytes are stripped only when no downstream record consumer needs them (client-side input tokenization disabled, no synthetic image/audio/video inputs, and raw payload export off). True forces stripping even when a consumer wants the bytes, disabling client-side input tokenization, media counting from request bodies, and raw request payload export. False always retains them. Auto-detection does not see media embedded in custom dataset payloads under server-token-count mode; set False explicitly for that case. |

Past this budget the operator gives up and marks the AIPerfJob Failed with the ResultsFetchFailed condition. WHY: sub-second benchmarks can race the controller's post-export shutdown — the marker has been written and key files exist on the controller PVC, but the operator's HTTP fetch hits a connection-refused or empty list as the controller container terminates. Set 0 to disable retries. |

Record aggregation trails the last request by a beat, so a single sample can leave status.phases showing isRecordsComplete=false on a run whose exports are complete. Set 0 to take exactly one sample. |
+| `AIPERF_RESULTS_PHASE_SETTLE_DELAY_SEC` | `2.0` | ≥ 0.1, ≤ 30.0 | Delay between the re-samples controlled by ``PHASE_SETTLE_ATTEMPTS``. The total wait is a hard ceiling on how long completion is delayed for a cosmetic status mirror. |

+| `AIPERF_SWEEP_CONTROLLER_STALE_CHILD_DELETION_TIMEOUT_SECONDS` | `60.0` | > 0, ≤ 600 | Max seconds the sweep-controller will wait for a same-named AIPerfJob from a prior sweep run to finish cascade-deletion before raising ChildNameConflictError. Hit when a user deletes and recreates a sweep with the same name while old children are still terminating. |
+| `AIPERF_SWEEP_CONTROLLER_STALE_CHILD_POLL_INTERVAL_SECONDS` | `2.0` | > 0, ≤ 30 | Poll interval (seconds) while waiting for a deleting same-named AIPerfJob to disappear. See STALE_CHILD_DELETION_TIMEOUT_SECONDS. |
+| `AIPERF_SWEEP_CONTROLLER_CANCEL_GRACE_SECONDS` | `120.0` | > 0, ≤ 3600 | Max seconds the sweep-controller will keep polling a child AIPerfJob for a terminal phase after requesting cancel before giving up and advancing the sweep. Bounds the post-cancel wait so a stuck child (stalled operator cancel path, wedged pod, repeatedly-failing JobSet delete) cannot wedge the whole sweep indefinitely. |
+| `AIPERF_SWEEP_CONTROLLER_SUMMARY_RACE_REFRESH_ATTEMPTS` | `15` | ≥ 0, ≤ 200 | How many times the sweep-controller re-reads a terminal child AIPerfJob whose ``status.summary`` AND ``status.runEpoch`` are both still unset before giving up on its metrics. The operator's completion handler stamps both fields from a code path that is not atomic with the phase write, so a fast child (concurrency=1, few requests) routinely reaches Completed first. This window must cover the whole completion handler — results fetch + retries, disk recovery, JobSet delete, retention pass — because the operator-API fallback needs ``status.runEpoch`` and short-circuits without it. Exhausting the window collapses that variation's SLA bracket to ``observed: null``, so err long: the loop exits the instant either field lands, and only a genuinely stuck completion pays the full wait. Set 0 to disable the settle loop entirely. |
+| `AIPERF_SWEEP_CONTROLLER_SUMMARY_RACE_REFRESH_SECONDS` | `2.0` | > 0, ≤ 60 | Delay between the child re-reads controlled by SUMMARY_RACE_REFRESH_ATTEMPTS. Attempts x this delay is the total grace granted to the operator's summary/runEpoch write. |
+| `AIPERF_SWEEP_CONTROLLER_CHILD_MISSING_TIMEOUT_SECONDS` | `300.0` | > 0, ≤ 3600 | Max seconds the sweep-controller will keep polling for a child AIPerfJob that has gone missing (404) before its terminal phase, with no cancel requested, before giving up and advancing the sweep. Hit when a user (or the kube garbage collector) deletes a child AIPerfJob out-of-band mid-run; without this bound the sequential sweep wedges forever on the deleted variation. |

+# Adaptive Search on Kubernetes
+
+Adaptive search lets the cluster choose its own sweep points instead of
+exhausting a grid. The same `BayesianSearchPlanner` (Optuna-backed, with
+the Gaussian-process path supplied by BoTorch via the `[botorch]` extra) used
+in-process by `aiperf profile --search-*` runs cluster-side when an
+`AIPerfSweep` CR sets `spec.sweep.type: adaptive_search`. The planner
+proposes one variation at a time; the sweep-controller pod creates a child
+`AIPerfJob` per trial of that variation (one when `multiRun.numRuns` is
+unset or 1), waits for them to terminate, scores the objective, and asks
+for the next point. Convergence detection (max iterations,
+improvement-patience plateau, or coefficient-of-variation plateau)
+terminates the loop early when further evaluations stop helping.
+
+Reach for adaptive search when the search space is too large to grid
+enumerate (e.g. concurrency 1–1000), when a single scalar objective
+captures what you care about, and when you want the proposed points
+materialized as ordinary `AIPerfJob`s so each iteration is durable,
+cancellable, and visible through normal `kubectl get aiperfjob`
+workflows. For the algorithm details, flag grammar, and
+`search_history.json` schema, defer to
+[Bayesian-Optimization Outer Loop](../sweeping/bayesian-optimization.md);
+for the in-process tutorial, see
+[Adaptive Search](../tutorials/adaptive-search.md).

+
+The kopf operator stays unaware of Bayesian Optimization: it only sees
+ordinary `AIPerfJob` create/delete events. Planner state — the Gaussian
+process model, trial history, and convergence accumulators — lives in the
+controller process. After a restart, the controller constructs a fresh planner
+and deterministically replays terminal child results through the canonical
+`ask()` / `tell()` loop before proposing a new point. `search_history.json`
+remains an output record rather than an input checkpoint; replay rebuilds it
+from the Kubernetes-owned children.
+
+If `sweep.randomSeed` is omitted, the Kubernetes plan builder derives a stable
+planner seed from the immutable `AIPerfSweep` `metadata.uid`. An explicit
+`randomSeed` always wins. Every child also carries
+`aiperf.nvidia.com/run-identity`, a SHA-256 hash of its exact generated
+`AIPerfJob.spec`. A deterministic child name is reused only when both ownership
+and this execution contract match. A missing or mismatched identity fails the
+sweep instead of feeding metrics from a different configuration into planner
+history.
+
+The optimization stack is pulled in through the AIPerf `[botorch]` extra
+(alias `[optuna]`) and is present on the controller-pod image; operator
+pods do not need it.

+the cost of triple the wall clock. Drop to `numRuns: 1` for fastest
+iteration and exactly one `AIPerfJob` per proposed point.
+
+## Multi-dimensional search
+
+Search over concurrency and Poisson rate jointly:
+
+```yaml
+spec:
+  sweep:
+    type: adaptive_search
+    planner: bayesian
+    searchSpace:
+      - path: phases.profiling.concurrency
+        lo: 1
+        hi: 500
+        kind: int
+      - path: phases.profiling.rate
+        lo: 1.0
+        hi: 50.0
+        kind: real
+    objectives:
+      - metric: output_token_throughput
+        stat: avg
+        direction: maximize
+    maxIterations: 40
+    nInitialPoints: 8
+  multiRun:
+    numRuns: 2
+```
+
+`kind: int` declares an integer dimension — Optuna suggests integer
+parameters natively, no rounding step — while `kind: real` keeps
+floats. `nInitialPoints` (default 5) becomes the sampler's
+`n_startup_trials`: that many randomly-drawn startup points are
+evaluated before the surrogate model takes over. Bump it for
+higher-dimensional spaces (rule of thumb: `>= 2 * len(searchSpace)`).
+
+## Status fields you can watch
+
+The CRD declares typed counters in `status`:
+
+| Field | Meaning under adaptive search |
+|---|---|
+| `status.phase` | `Pending` -> `Running` -> `Aggregating` -> `Succeeded` / `Failed` / `PartiallyFailed` / `Cancelled`. |
+| `status.totalVariations` | Upper bound: equal to `maxIterations`. Actual count may be lower on early stop. |
+| `status.maxTotalRuns` | Upper bound: `maxIterations * multiRun.numRuns`. |
+| `status.completedRuns` | Authoritative count of finished child `AIPerfJob`s. |
+| `status.failedRuns` | Authoritative failure count, tallied from child phases. `failurePolicy` decides whether that count aborts the sweep, it does not feed the count. |
+| `status.runEpoch` | Integer sweep-run key (`int64`) used in the on-disk path: epoch-seconds, optionally suffixed with six digits. A fractional creation timestamp contributes real microseconds; a whole-second Kubernetes timestamp contributes a deterministic UID-derived suffix so rapid same-name recreation cannot reuse an archive. A `creationTimestamp` that cannot yield such a key (anything before 1970, which makes epoch-seconds negative) is rejected at admission with a `Failed` phase rather than silently stored, because the key doubles as the results directory name. |
+
+`status` is a preserve-unknown object. `runStates`, `currentChildRef`,
+`currentCell`, and `aggregation` are declared there as open objects —
+the keys exist in the CRD but their inner shape is unvalidated.
+
+Both `totalVariations` and `maxTotalRuns` are upper bounds — early
+plateau or improvement-patience convergence shrinks the actual count
+(the controller rewrites `totalVariations` to the number of distinct
+variation indexes it actually ran). This mirrors how the trial-level
+convergence rule (`multiRun.convergence`) can stop a grid sweep's cell
+short of `multiRun.numRuns`.
+
+```bash
+$ kubectl -n bench get aiperfsweep bo-concurrency-llama8b
+NAME                     PHASE       COMPLETED   TOTAL   FAILED   CURRENT   AGE
+bo-concurrency-llama8b   Succeeded   54          90      0                  12m
+```
+
+The full BO trajectory — every proposed point, the per-iteration
+objective, the running best, and the convergence reason — lives in
+`search_history.json`, not on the CR. See
+[Output layout](#output-layout) below and the
+[search_history.json schema](../api/search-history.md).
+
+A compact projection of that artifact is served on the sweep detail route
+as `search_summary`, so the dashboard and any API client can read the
+planner's own verdict without downloading the trajectory:
+
+```bash
+$ curl -s http://aiperf-operator.aiperf-system:8081/api/v1/sweeps/bench/bo-concurrency-llama8b \
+    | jq '.search_summary | {convergence_reason, stop_kind, iteration_count,
+                             sla_filter_count, best_trials, boundary_summary}'
+```
+
+| Field | Meaning |
+|---|---|
+| `convergence_reason` | Verbatim planner stop reason; `null` mid-loop or after an abnormal exit. |
+| `stop_kind` | `converged` / `budget_exhausted` / `incomplete` — the classification of that reason, so clients need not track a growing string enum. |
+| `iteration_count`, `feasible_iteration_count` | Iterations recorded, and how many met every SLA filter. |
+| `sla_filter_count` | How many SLA filters were configured. **Zero makes every `feasible` flag vacuously true** — check it before rendering any feasibility claim. |
+| `objectives` | The optimized targets, with `direction` normalized to lowercase. |
+| `best_trials` | Planner-selected winner (Pareto front for multi-objective), capped at 20 with `best_trials_truncated`. Each entry's `objective_values` is **positional against `objectives`** and is never compacted: an objective the scorer could not produce keeps its slot as an explicit `null`, so `objective_values[i]` always belongs to `objectives[i]`. A `null` there means "not measured for this trial" and must be rendered as such — substituting a neighbouring value silently relabels it. The whole field is `null` when the trial was not scored at all. |
+| `boundary_summary` | The empirical SLA boundary on the swept axis: `swept_dim_path`, `feasible_max`, and `infeasible_min` — the infeasible edge carries the `first_breach` that defined it. `null` for multi-dimensional searches and for runs with no iterations. |
+
+`search_summary` is `null` for grid-family sweeps, for adaptive sweeps
+whose trajectory has not been harvested to the operator PVC yet, and
+whenever the artifact is unreadable — a missing verdict degrades the
+response, it never fails it. The complete `search_history.json` remains
+downloadable from the per-epoch sweep artifacts routes.
+
+## Mutual exclusion rules
+
+In the flat spec envelope, `adaptive_search` is one of the
+`sweep.type` discriminator values (alongside `grid`, `zip`, `scenarios`,
+`sobol`, and `latin_hypercube`), so "adaptive plus grid" is not even
+expressible — the discriminator picks one. The remaining gates protect
+the cardinality contract:
+
+| Combination | Outcome | Enforced by |
+|---|---|---|
+| `kind: AIPerfJob` + `spec.sweep` (any type) | Rejected at admission — single benchmarks must use `kind: AIPerfJob` with `spec.sweep` unset | CRD `x-kubernetes-validations` rule (`!has(self.sweep)` on AIPerfJob) |
+| `kind: AIPerfSweep` without `spec.sweep` | Rejected at admission — sweeps must declare a `sweep` block | CRD `x-kubernetes-validations` rule (`has(self.sweep)` on AIPerfSweep) |
+| `sweep.type: adaptive_search` + `spec.benchmark.sweep` | Silently pruned at admission — `spec.benchmark` is a structural node with no `x-kubernetes-preserve-unknown-fields`, so the apiserver drops the unknown key and the nested block never reaches the controller. Sweep axes belong on the parent CR, not embedded in the per-iteration body | Structural-schema pruning on `spec.benchmark`; `BenchmarkConfig` additionally has no `sweep` field and forbids extras |
+| Per-iteration `AIPerfJob` containing magic-list flags (`--concurrency 10,20,30`) | Rejected inside each child by `_reject_in_process_sweep_under_operator` | `src/aiperf/cli_runner/_multi_run.py` |
+
+These prevent sweeping on top of sweeping and keep a single source of
+truth for variation generation.
+
+## Operator-managed gate exception
+
+The operator sets `AIPERF_OPERATOR_MANAGED=1` in every controller and
+worker pod, and `cli_runner._reject_in_process_sweep_under_operator`
+hard-fails any in-process magic-list sweep under that flag — so the
+cluster never sweeps on top of a sweep. **Adaptive search is the
+exception**: the controller pod is the BO driver, and each per-iteration
+child `AIPerfJob` sees a single-config plan (no `is_sweep` shape), so the
+gate never fires for adaptive runs. The exemption is documented in the
+`_reject_in_process_sweep_under_operator` docstring
+(`src/aiperf/cli_runner/_multi_run.py`).
+
+## Cancellation behaviour
+
+Patching the parent `AIPerfSweep` with `spec.cancel: true` is cooperative
+end to end:
+
+1. A background poller in the sweep-controller pod
+   (`_poll_cancel_flag` in `sweep_controller/main.py`) re-reads the parent
+   CR and flips an in-process cancel flag when `spec.cancel` is true.
+2. The adaptive loop and the child-wait loop both consult that flag as a
+   `cancel_check` callable at their `await` boundaries.
+3. The currently-running child `AIPerfJob` is patched with
+   `spec.cancel: true` (`K8sChildJobExecutor._patch_child_cancel`), drains
+   to a terminal phase, and contributes its results.
+4. The controller skips remaining iterations, runs aggregation over the
+   children that did complete, and flushes `search_history.json` with
+   `convergence_reason: "cancelled"`.
+
+`search_history.json` is rewritten after every iteration. Cancellation keeps
+the completed prefix immediately; after a controller restart, the same prefix
+is reconstructed by reusing terminal children and replaying their metrics into
+the restart-stable planner before execution advances.
+
+## Output layout
+
+Artifacts land under the operator's `AIPERF_RESULTS_DIR` PVC (default
+`/data`), scoped by namespace, sweep name, and the sweep run-epoch:
+
+```
+<AIPERF_RESULTS_DIR>/
+  <namespace>/
+    sweeps/
+      <sweep-name>/
+        <sweep-run-epoch>/
+          search_history.json          # BO trajectory + convergence_reason
+          aggregate.json               # durable parent aggregate
+          children.json                # child manifest
+          sweep_aggregate/             # mode-agnostic per-combination aggregate
+            profile_export_aiperf_sweep.json
+            profile_export_aiperf_sweep.csv
+            manifest.json              # epoch lineage of every child run
+    <sweep-name>-v00-t0/               # per-iteration child AIPerfJob
+      <child-run-epoch>/
+        profile_export_aiperf.json     # full per-trial artifacts
+        ...
+    <sweep-name>-v00-t1/
+    <sweep-name>-v01-t0/
+    ...
+```
+
+The operator harvests the whole tree from the sweep-controller's results
+sidecar before the JobSet is deleted (the controller pod's `/results` is
+an `emptyDir`), re-rooting it onto the operator PVC.
+
+Per-iteration child names follow the same `<sweep>-v<NN>[-t<N>]` budget
+as grid sweeps (`build_child_name` in `sweep_controller/_naming.py`):
+the variation index is the BO iteration index (`-v00` is the first
+proposed point), and the trial suffix is present whenever
+`multiRun.numRuns > 1` or `multiRun.convergence` is set. Each child sits
+at the same path layer as a standalone `AIPerfJob` and is reachable
+through the standard `/api/v1/results/<ns>/<sweep>-v00-t1/` endpoints.
+
+`sweep_aggregate/` carries the same per-combination CSV/JSON schema
+produced by grid sweeps — `aggregate_sweep_and_export` groups by stamped
+`variation_values` and is mode-agnostic, so downstream readers do not
+need to know the sweep was adaptive.

+# AI Agent Debugging Guide for AIPerf on Kubernetes
+
+This guide is written for AI coding agents (Claude, Copilot, Cursor, etc.) that need to diagnose and fix AIPerf Kubernetes benchmark issues. Every command produces machine-parseable output. Every decision point has explicit criteria. No ambiguity.
+
+---
+
+## How to Use This Guide
+
+1. Start at [Triage](#triage) to classify the problem
+2. Follow the decision tree for your problem class
+3. Each section gives you the exact command, the JSON schema of the output, and the decision logic
+4. Prefer structured output where it exists — `aiperf kube preflight` and `aiperf kube validate` take `--output json`. Others do not: `aiperf kube debug` emits human-readable text only, and `--output` on `aiperf kube results` is a destination directory, not a format.
+
+---
+
+## Triage
+
+Run this command first. It gives you everything you need to classify the problem:
+
+```bash
+kubectl get aiperfjob <NAME> -n <NS> -o json | python3 -c "
+import sys, json
+st = json.load(sys.stdin).get('status', {})
+w = st.get('workers', {})
+print(json.dumps({
+    'phase': st.get('phase'),
+    'subPhase': st.get('subPhase'),
+    'currentPhase': st.get('currentPhase'),
+    'workers_ready': w.get('ready', 0),
+    'workers_total': w.get('total', 0),
+    'conditions': st.get('conditions', []),
+    'error': st.get('error'),
+}, indent=2))
+"
+
+# Pod-level triage (container states, recent events, node pressure)
+aiperf kube debug --job-id <NAME> --namespace <NS>
+```
+
+### Decision Tree
+
+Branch on `status.phase` from the CR, then on what `aiperf kube debug` reports.
+(The `health` / `error_rate` rollups came from the removed live-watch command;
+derive the equivalent from pod state and metrics as shown below.)
+
+```
+phase == "Completed"
+  -> Benchmark finished. Go to [Collect Results](#collect-results).
+
+phase == "Failed"
+  -> Go to [Failed Job](#failed-job).
+
+phase == "Cancelled"
+  -> Job was cancelled. Check if intentional. No action needed.
+
+phase == "Pending" for more than ~60s
+  -> Go to [Stuck in Pending](#stuck-in-pending).
+
+phase == "Queued"
+  -> Job is waiting for Kueue admission. Go to [Kueue Issues](#kueue-issues).
+
+phase == "Initializing" for more than ~120s
+  -> Go to [Stuck Initializing](#stuck-initializing).
+
+phase == "Running", and `aiperf kube debug` shows a pod with restarts > 3
+  -> Go to [Crash Loop](#crash-loop).
+
+phase == "Running", and `aiperf kube debug` reports an OOM-killed pod
+  -> Go to [OOM Kills](#problem-oom-kills).
+
+phase == "Running", but status.phases.*.requestsCompleted is not advancing
+  -> Go to [Stalled Benchmark](#stalled-benchmark).
+
+phase == "Running", and request_error_rate.avg > 5 (percent) in
+status.liveMetrics.metrics -- this is the only error signal published while a
+job runs, because error_request_count is ERROR_ONLY and is filtered out
+  -> Go to [High Error Rate](#high-error-rate).
+
+phase == "Running" and none of the above
+  -> Benchmark is running normally. Monitor with:
+     aiperf kube attach
+```
+
+---
+
+## Problem: Failed Job
+
+### Gather Information
+
+```bash
+# Get the error message from the CR status
+kubectl get aiperfjob <JOB_NAME> -n <NAMESPACE> -o json | \
+  python3 -c "import sys,json; s=json.load(sys.stdin)['status']; print(json.dumps({'phase':s.get('phase'),'error':s.get('error'),'conditions':s.get('conditions',[])}, indent=2))"
+```
+
+```bash
+# Get controller pod logs (last 50 lines)
+aiperf kube logs <JOB_ID> --container control-plane --tail 50
+```
+
+```bash
+# Run full diagnostics
+aiperf kube debug --job-id <JOB_ID> --verbose
+```
+
+### Common Failure Patterns
+
+| Error contains | Root cause | Fix |
+|---|---|---|
+| `preflight` | Cluster validation failed | Run `aiperf kube preflight -o json` and fix failing checks |
+| `endpoint` or `health check` | Inference server unreachable | Verify endpoint URL resolves from inside the cluster |
+| `timeout` | Benchmark exceeded `timeoutSeconds` | Increase `spec.timeoutSeconds` or set to `0` |
+| `ConfigMap` or `size` | Config too large for K8s 1MiB limit | Reduce config size |
+| `image` or `pull` | Container image not accessible | Check image name and pull secrets |
+| `RBAC` or `forbidden` | Missing permissions | Check service account and role bindings |
+
+---
+
+## Problem: Stuck in Pending
+
+Pods cannot be scheduled. Get the reason:
+
+```bash
+# Check pod events for scheduling failures
+kubectl get pods -n <NAMESPACE> -l aiperf.nvidia.com/job-id=<JOB_ID> -o json | \
+  python3 -c "
+import sys, json
+pods = json.load(sys.stdin)['items']
+for pod in pods:
+    name = pod['metadata']['name']
+    conditions = pod['status'].get('conditions', [])
+    for c in conditions:
+        if c.get('type') == 'PodScheduled' and c.get('status') == 'False':
+            print(json.dumps({'pod': name, 'reason': c.get('reason'), 'message': c.get('message')}))
+"
+```
+
+```bash
+# Check node resources
+kubectl get nodes -o json | python3 -c "
+import sys, json
+nodes = json.load(sys.stdin)['items']
+for n in nodes:
+    alloc = n['status']['allocatable']
+    print(json.dumps({
+        'node': n['metadata']['name'],
+        'cpu': alloc.get('cpu'),
+        'memory': alloc.get('memory'),
+        'gpu': alloc.get('nvidia.com/gpu', '0'),
+    }))
+"
+```
+
+### Decision Logic
+
+| Scheduling message contains | Fix |
+|---|---|
+| `Insufficient cpu` or `Insufficient memory` | Reduce worker count: `--total-workers <lower_number>` |
+| `nvidia.com/gpu` | No available GPU nodes. Wait or add capacity. |
+| `didn't match Pod's node affinity/selector` | Fix `spec.podTemplate.nodeSelector` to match existing nodes |
+| `had untolerated taint` | Add tolerations to `spec.podTemplate.tolerations` |
+| `quota` | Namespace ResourceQuota exhausted. Request more or use different namespace. |
+

+
+## Problem: Kueue Issues
+
+```bash
+# Check if the workload is admitted
+kubectl get workloads -n <NAMESPACE> -o json | python3 -c "
+import sys, json
+items = json.load(sys.stdin)['items']
+for w in items:
+    name = w['metadata']['name']
+    conditions = w.get('status', {}).get('conditions', [])
+    admitted = any(c['type'] == 'Admitted' and c['status'] == 'True' for c in conditions)
+    print(json.dumps({'workload': name, 'admitted': admitted, 'conditions': [{'type': c['type'], 'status': c['status'], 'message': c.get('message','')} for c in conditions]}))
+"
+```
+
+```bash
+# Check ClusterQueue capacity
+kubectl get clusterqueues -o json | python3 -c "
+import sys, json
+items = json.load(sys.stdin)['items']
+for q in items:
+    print(json.dumps({
+        'name': q['metadata']['name'],
+        'flavors': q.get('status', {}).get('flavorsReservation', []),
+        'pending': q.get('status', {}).get('pendingWorkloads', 0),
+    }))
+"
+```
+
+If the workload is not admitted, the queue is full. Wait for other workloads to complete, or adjust priority with `spec.scheduling.priorityClass`.
+
+---
+
+## Problem: Stuck Initializing
+
+Workers are starting but not all are ready yet.
+
+```bash
+# Check which pods are not ready
+kubectl get pods -n <NAMESPACE> -l aiperf.nvidia.com/job-id=<JOB_ID> -o json | \
+  python3 -c "
+import sys, json
+pods = json.load(sys.stdin)['items']
+for pod in pods:
+    containers = pod['status'].get('containerStatuses', [])
+    for c in containers:
+        if not c.get('ready', False):
+            waiting = c.get('state', {}).get('waiting', {})
+            print(json.dumps({
+                'pod': pod['metadata']['name'],
+                'container': c['name'],
+                'ready': False,
+                'waiting_reason': waiting.get('reason', 'unknown'),
+                'waiting_message': waiting.get('message', ''),
+                'restarts': c.get('restartCount', 0),
+            }))
+"
+```
+
+| Waiting reason | Fix |
+|---|---|
+| `ContainerCreating` | Normal -- image is pulling. Wait. |
+| `ImagePullBackOff` | Image does not exist or no pull secret. Fix image or add `--image-pull-secrets`. |
+| `CrashLoopBackOff` | Container crashes on startup. Check logs with `aiperf kube logs --container <name>`. |
+| `CreateContainerConfigError` | Missing ConfigMap, Secret, or volume. Check the pod events. |
+
+---
+
+## Problem: Crash Loop
+
+A pod is restarting repeatedly (>3 restarts).
+
+```bash
+# Get logs from the previous (crashed) container
+kubectl logs -n <NAMESPACE> <POD_NAME> --previous -c <CONTAINER_NAME> --tail=50
+```
+
+```bash
+# Get the exit code
+kubectl get pod -n <NAMESPACE> <POD_NAME> -o json | python3 -c "
+import sys, json
+pod = json.load(sys.stdin)
+for c in pod['status'].get('containerStatuses', []):
+    term = c.get('lastState', {}).get('terminated', {})
+    if term:
+        print(json.dumps({
+            'container': c['name'],
+            'exit_code': term.get('exitCode'),
+            'reason': term.get('reason'),
+            'message': term.get('message', ''),
+        }))
+"
+```
+
+| Exit code | Meaning | Fix |
+|---|---|---|
+| 137 | SIGKILL (OOM or external kill) | Increase memory limits. See [OOM Kills](#problem-oom-kills). |
+| 1 | Application error | Read the logs. Common: bad config, missing model, endpoint unreachable. |
+| 2 | Python syntax/import error | Image may be wrong version. Verify `--image`. |
+
+---
+
+## Problem: OOM Kills
+
+A pod was killed because it exceeded its memory limit.
+
+```bash
+# Confirm OOM and get memory limits
+kubectl get pod -n <NAMESPACE> <POD_NAME> -o json | python3 -c "
+import sys, json
+pod = json.load(sys.stdin)
+for c in pod['spec']['containers']:
+    limits = c.get('resources', {}).get('limits', {})
+    print(json.dumps({'container': c['name'], 'memory_limit': limits.get('memory', 'none')}))
+for c in pod['status'].get('containerStatuses', []):
+    term = c.get('lastState', {}).get('terminated', {})
+    if term.get('reason') == 'OOMKilled':
+        print(json.dumps({'container': c['name'], 'oom_killed': True}))
+"
+```
+
+### Fixes (in priority order)
+
+1. **Reduce connections per worker** -- Lower `spec.connectionsPerWorker` (default: 100). Each connection holds request/response buffers in memory. The field is immutable after creation, so this means recreating the AIPerfJob.
+
+2. **Increase workers, reduce per-pod** -- Use more pods with fewer workers each. Lower `spec.benchmark.runtime.workersPerPod` in the CR (the cluster-wide worker total stays `--total-workers`; this knob only controls how that total is fanned across pods).
+
+3. **Raise the worker-pod memory budget** -- `AIPERF_K8S_WORKER_POD_MEMORY` (default `6Gi`) is read by the process that renders the JobSet, so it must be set on the operator container. Putting it in `spec.podTemplate.env` has no effect on container resources:
+   ```bash
+   kubectl set env -n aiperf-system deploy/aiperf-operator \
+     AIPERF_K8S_WORKER_POD_MEMORY=8Gi
+   ```
+
+4. **Drop the cgroup ceiling** -- `spec.resourceMode: burstable` (the default) sets requests without limits, so a container is not cgroup-OOM-killed for exceeding its request. Only `guaranteed` mode applies `requests == limits`. This field is also immutable after creation.
+

+## Problem: Stalled Benchmark
+
+Running phase but no progress (0 throughput, 0 requests completed).
+
+```bash
+# Check Dynamo endpoint reachability from inside the cluster
+# URL pattern: http://{deploy-name}-frontend.{namespace}.svc:8000/v1/models

+
+```bash
+# Check controller logs for endpoint errors
+aiperf kube logs <JOB_ID> --container control-plane --tail 30 2>&1 | grep -i "error\|timeout\|refused\|unreachable"
+```
+
+| Symptom | Fix |
+|---|---|
+| `curl` returns `http_code: 0` or `Connection refused` | Endpoint URL wrong or Dynamo frontend not running. Verify URL pattern: `http://{deploy-name}-frontend.{namespace}.svc:8000/v1`. Check Dynamo pods: `kubectl get pods -n dynamo-server`. |
+| `curl` returns `http_code: 200` but benchmark stalled | Workers may not be connecting. Check ZMQ connectivity in controller logs. |
+| `curl` times out | Network policy blocking traffic, or Dynamo workers are still loading the model. Check pod logs: `kubectl logs -n dynamo-server -l app.kubernetes.io/managed-by=dynamo-operator`. |

+
+## Problem: High Error Rate
+
+More than 5% of requests are failing.
+
+```bash
+# Get live metrics with error breakdown
+kubectl get aiperfjob <NAME> -n <NS> \
+  -o jsonpath='{.status.liveMetrics.metrics}' | python3 -m json.tool
+```
+
+| Error rate range | Likely cause | Fix |
+|---|---|---|
+| 5-20% | Endpoint overloaded | Reduce `concurrency` in the phase config |
+| 20-50% | Model or endpoint errors | Check endpoint logs for 500/503 errors |
+| >50% | Endpoint down or misconfigured | Verify model name matches what the server is serving |
+| 100% | Wrong endpoint URL or auth required | Fix URL or add API key via `--env-from-secrets` |
+

+
+## Collect Results
+
+```bash
+# Download all artifacts (default: fetched from operator storage,
+# which works even after pods are deleted)
+aiperf kube results <JOB_ID> --output ./artifacts
+
+# Retrieve directly from benchmark pods instead of operator storage
+aiperf kube results <JOB_ID> --from-pods --output ./artifacts
+
+# Read the summary metrics. Top-level keys are AIPerf metric tags; each maps
+# to an object of stats (unit, avg, p50, p90, p99, min, max, std, count, sum).
+cat ./artifacts/profile_export_aiperf.json | python3 -c "
+import sys, json
+data = json.load(sys.stdin)
+def stat(tag, key='avg'):
+    m = data.get(tag)
+    return m.get(key) if isinstance(m, dict) else None
+print(json.dumps({
+    'request_throughput': stat('request_throughput'),
+    'request_latency_avg': stat('request_latency'),
+    'request_latency_p99': stat('request_latency', 'p99'),
+    'ttft_avg': stat('time_to_first_token'),
+    'ttft_p99': stat('time_to_first_token', 'p99'),
+    'itl_avg': stat('inter_token_latency'),
+    'output_token_throughput': stat('output_token_throughput'),
+    'request_count': stat('request_count'),
+    'error_request_count': stat('error_request_count'),
+    'request_error_rate_pct': stat('request_error_rate'),
+}, indent=2))
+"
+```
+
+`request_count` counts successful requests only and `error_request_count`
+counts failures, so the grand total is their sum. `error_request_count` is
+omitted entirely on a clean run.

+
+# Attach to a Running Benchmark
+
+`aiperf kube attach` re-connects to an `AIPerfJob` that is already running in the cluster and streams its progress to your terminal until the benchmark finishes. It is the command you reach for when an earlier `aiperf kube profile` invocation was detached (Ctrl-C, closed laptop, disconnected VPN, separate deploy host) and you want to pick the session back up from another shell.
+
+Attach is intentionally narrow:
+
+- It does **not** deploy, modify, or cancel the `AIPerfJob`.
+- It does **not** download results after completion. Use `aiperf kube results` for that.
+- It does **not** poll the Kubernetes API for snapshots. Use `aiperf kube list` or `aiperf kube debug` for that.
+
+Contrast with the neighbouring commands:
+
+| Command | Shape | When to use |
+|---|---|---|
+| `aiperf kube attach` | Live WebSocket stream, exits on completion | Re-join a detached run in progress |
+| `aiperf kube list` | Polled CR summary | See phase / pod status at a glance |
+| `aiperf kube logs` | Raw container log stream | Debug a misbehaving container |
+| `aiperf kube results` | Artifact download | After the run has completed |
+
+---
+
+## Quick Reference
+
+```bash
+# Attach to the most recently deployed benchmark
+aiperf kube attach
+
+# Attach to a specific job by ID
+aiperf kube attach aiperf-bench-7f2a
+
+# Attach in a specific namespace
+aiperf kube attach aiperf-bench-7f2a --namespace aiperf-bench
+
+# Use a fixed local port instead of an ephemeral one
+aiperf kube attach aiperf-bench-7f2a --port 9091
+
+# Attach to one variation (and trial) of an AIPerfSweep
+aiperf kube attach my-sweep -v 7
+aiperf kube attach my-sweep -v 5 -t 0
+```
+

+
+## CLI Reference
+
+```text
+aiperf kube attach [JOB_ID] [OPTIONS]
+```
+
+| Argument / Flag | Default | Description |
+|---|---|---|
+| `JOB_ID` (positional) | last deployed job | The `AIPerfJob` CR name — or an `AIPerfSweep` name, when combined with `-v` — to attach to. If omitted, the CLI reads `~/.aiperf/last_kube_benchmark.json`. |
+| `-p`, `--port` | `0` | Local port for the `kubectl port-forward` tunnel. `0` asks the kernel for an ephemeral port, which avoids conflicts with other `aiperf kube` sessions on the same machine. |
+| `-v`, `--variation` | unset | When `JOB_ID` names an `AIPerfSweep`, the child variation index (`0`..`199`). Resolves to the child `AIPerfJob` named `<sweep>-v<idx:02d>`. |
+| `-t`, `--trial` | unset | Trial index (`0`..`9`) within a sweep variation, resolving to `<sweep>-v<idx:02d>-t<trial>`. Requires `-v`. |
+| `--ignore-not-found` | `false` | Exit `0` instead of `1` when the target benchmark does not exist. Mirrors `kubectl`'s flag of the same name; the error is still printed. |
+| `-n`, `--namespace` | last-benchmark namespace, else the kubeconfig context namespace | Kubernetes namespace containing the `AIPerfJob`. |
+| `--kubeconfig` | unset | Path to a kubeconfig file. When unset, the CLI first tries in-cluster config, then the default kubeconfig resolution. |
+| `--kube-context` | unset | Context name to select inside the kubeconfig. |
+
+`--namespace`, `--kubeconfig`, and `--kube-context` are the composite options declared on `KubeManageOptions` and are shared with every other `aiperf kube` subcommand.
+
+---
+
+## Default Job-ID Resolution
+
+If you do not pass a positional `job_id`, the CLI resolves it from the file written by the most recent `aiperf kube profile` (or `aiperf kube sweep`):
+
+```text
+~/.aiperf/last_kube_benchmark.json
+```
+
+The file stores a `{"job_id", "namespace", "name", "kind"}` record — `job_id` and `namespace` are always present, `name` and `kind` are written only when known (see `save_last_benchmark` / `get_last_benchmark` in `aiperf.kubernetes.console`). `resolve_job_id_and_namespace` reads it and prints a one-line info banner so you can confirm which job you are attaching to.
+
+**Multi-cluster pitfall.** The last-benchmark file is keyed by nothing except "the last `aiperf kube` deploy that ran on this workstation". If you routinely switch between clusters or kubeconfig contexts, the stored `job_id` / `namespace` may belong to a *different* cluster than the one your current `--kube-context` targets. The symptom is "No AIPerf job found with ID: ..." even though you just deployed successfully — the job exists, but not on the cluster you are now pointing at. Pass the `job_id` explicitly, or re-confirm your context with `kubectl config current-context` before attaching.

+        WS-->>CLI: progress / metrics / worker status
+    end
+    CLI->>PF: terminate
+    CLI-->>User: exit 0
+```
+
+The concrete steps performed by `attach_to_benchmark` (in `aiperf/kubernetes/attach.py`) are:
+
+1. **Resolve the job.** `resolve_job` queries `AIPerfJob` CRs first. If the CR is missing, it falls back to `find_jobset` so that jobs deployed in direct-mode (JobSet-only, no operator) are still reachable. See [Direct-mode vs operator-mode](#direct-mode-vs-operator-mode).
+2. **Short-circuit on terminal phase.** If the CR's `status.phase` is already `Completed` or `Failed`, `attach` exits early with a pointer at `aiperf kube results` or `aiperf kube logs` respectively. On failure, it best-effort prints the controller pod's last 30 log lines.
+3. **Locate the controller pod.** `find_controller_pod` returns the `(pod_name, phase)` pair for the control-plane pod. If no pod exists, or the pod is not `Running`, attach prints a warning and exits cleanly (exit code 0) — this is the normal outcome when the CR is still `Pending` and pods have not been scheduled yet.
+4. **Port-forward to the controller API.** `port_forward_with_status` spawns `kubectl port-forward -n NS pod/POD LOCAL:9090` (where `9090` is `K8sEnvironment.PORTS.API_SERVICE`). When `--port 0` is passed, `LOCAL` is `0`, and the actual port is parsed from kubectl's `"Forwarding from 127.0.0.1:NNNN"` stdout line.
+5. **Open the progress WebSocket.** `stream_progress` builds `ws://localhost:PORT/ws`, subscribes to the progress message types enumerated in `WS_MESSAGE_TYPES` (phase start/progress/complete, realtime metrics, worker status summary, all-records-received), and logs each frame to the `aiperf.kube` rich logger.
+6. **Exit on terminal message.** The subscription stops as soon as an `ALL_RECORDS_RECEIVED` frame is observed. The port-forward is then terminated by the `async with` exit handler.
+
+---
+
+## Port-Forward Behavior
+
+The port-forward is managed by `aiperf.kubernetes.port_forward` and is shared by all `aiperf kube` commands that need to talk to the controller API. Key tunables (all seconds):
+
+| Parameter | Value | Purpose |
+|---|---|---|
+| `_PORT_FORWARD_TIMEOUT` | `60.0` | Single wall-clock budget covering both `kubectl port-forward` printing its `"Forwarding from ..."` ready line and the `/health` probe answering. Exceeding it during verification raises `"Port-forward API verification exceeded budget (60.0s)"`. |
+| `_API_INITIAL_DELAY` | `0.5` | Grace delay before the first `GET /health` probe, giving kubectl time to wire the tunnel. |
+| `_API_RETRY_DELAY` | `2.0` | Sleep between port-forward restart attempts when `/health` fails. |
+| `_API_MAX_RETRIES` | `10` | Maximum number of port-forward restarts while waiting for the API to answer. |
+| `_PROCESS_CLEANUP_TIMEOUT` | `5.0` | Graceful-shutdown grace period for the `kubectl port-forward` child process. |
+| pod-liveness probe interval | `10.0` | Background task runs `kubectl get pod ... -o name` every 10 s; if it returns non-zero, the port-forward is terminated. |
+
+On top of the port-forward, `stream_progress_from_api` applies **WebSocket reconnection** with exponential backoff:
+
+- `_WS_INITIAL_BACKOFF` = `1.0` s
+- `_WS_MAX_BACKOFF` = `30.0` s (doubling per failure)
+- `_WS_HEARTBEAT` = `30` s (aiohttp heartbeat ping)
+- `max_retries` = `10` (`WS_MAX_RETRIES` in `ui_dispatch.py`)
+
+After 10 consecutive failed reconnects, `ConnectionError` is raised with the underlying `aiohttp.ClientError` / `asyncio.TimeoutError` preserved as `__cause__`, and `cli_utils.exit_on_error` converts that into a non-zero exit.
+
+---
+
+## Signals and Exit Codes
+
+| Scenario | Exit code | Notes |
+|---|---|---|
+| Benchmark completes (`ALL_RECORDS_RECEIVED`) | `0` | Port-forward is torn down cleanly; the `AIPerfJob` continues running to completion on the cluster. |
+| Short-circuit on `phase=Completed` / `phase=Failed` | `0` | No port-forward is opened; the CLI prints a pointer to `results` / `logs`. |
+| `Ctrl-C` during streaming (`KeyboardInterrupt`) | non-zero | `exit_on_error` deliberately re-raises `KeyboardInterrupt` rather than swallowing it. **The remote benchmark is not affected** — attach only tears down its own port-forward and WebSocket. |
+| `resolve_job` could not find the CR or JobSet | `1` | The error is printed via `print_error` and the command exits non-zero, so `aiperf kube attach` is usable as a CI existence check. Re-run `aiperf kube list` to enumerate available jobs. Pass `--ignore-not-found` to force exit `0` in a cleanup script that must tolerate an already-deleted benchmark. |
+| No `job_id` given and no last-benchmark record | `1` | Same path: the target could not be addressed at all. `--ignore-not-found` also covers this case. |
+| WebSocket reconnection budget exhausted | `1` | Wrapped by `cli_utils.exit_on_error(title="Error Attaching to Benchmark")`. |
+| `kubectl port-forward` budget exhausted | `1` | Same error wrapper; stderr from `kubectl` is surfaced in the message. |
+
+Attach is safe to interrupt at any time. The CR, JobSet, and pods are owned by the cluster — the CLI only holds a read-only WebSocket subscription.
+
+---
+
+## Direct-Mode vs Operator-Mode
+
+`resolve_job` is dual-mode by design:
+
+- **Operator-mode** (the default): `aiperf kube profile` creates an `AIPerfJob` CR, and the in-cluster operator reconciles it into a JobSet. `find_aiperf_job` matches the CR directly.
+- **Direct-mode**: `aiperf kube profile --no-operator` skips the CR and creates a JobSet. When no `AIPerfJob` exists, `resolve_job` falls back to `find_jobset` and wraps the returned `JobSetInfo` as a minimal `AIPerfJobInfo` so the rest of the attach flow is identical.
+
+You do not need to tell `attach` which mode the job was deployed in — the fallback is automatic. In direct mode the `phase` that drives the terminal short-circuit comes from `JobSetInfo._parse_status`, which maps the JobSet's `Completed` condition to `"Completed"` and a `Failed` condition with a failed `controller` replicated job to `"Failed"`. Everything else — including a JobSet that has failed only on the worker side — reports `"Running"`, so `attach` will proceed to look for the controller pod. A run that is still in flight is detected as complete the same way in both modes: via the `ALL_RECORDS_RECEIVED` WebSocket message.
+
+---
+
+## Troubleshooting
+
+**"No AIPerf job found with ID: ..."**
+The `job_id` you passed (or the one stored in `~/.aiperf/last_kube_benchmark.json`) does not exist in the resolved namespace. Note that omitting `--namespace` does **not** search cluster-wide: `resolve_job_id_and_namespace` substitutes the namespace from the last-benchmark file, or, when you passed an explicit `job_id`, the one your kubeconfig context sets. Run `aiperf kube list -A` to see what is actually deployed, and confirm your current kubeconfig context matches the cluster you deployed to.
+
+**"Port-forward did not become ready within 60.0s"**
+`kubectl port-forward` never printed its ready line. Common causes: the controller pod is `CrashLoopBackOff`, the pod was evicted, or a network policy is blocking pod-to-apiserver traffic. Check `aiperf kube debug` for pod phases and `aiperf kube logs --container control-plane` for the controller's startup errors.
+
+**"Port-forward failed after 10 retries"**
+The tunnel connected but `GET /health` on the API port never returned. Most commonly this means the controller is alive but has not yet bound the API server (still executing the `INITIALIZING` phase) — retry after 30 s. If the problem persists, inspect the controller pod logs for API-service binding errors.
+
+**"Connection lost, retrying in Ns..."**
+The progress WebSocket dropped and is being re-opened. A handful of these during a long run are expected (e.g. when the apiserver throttles the port-forward). Only after 10 consecutive failures will attach give up; at that point the underlying `aiohttp.ClientError` is surfaced in the exception chain.
+
+**Local port conflict (`bind: address already in use`)**
+You passed `--port N` and something else on your machine is already listening on `N`. Either free the port, pick a different one, or drop the flag to get an ephemeral port.
+
+**Auth errors (`Unauthorized` / `forbidden`)**
+In an interactive terminal, `Unauthorized` (HTTP 401) causes AIPerf to wait while
+you complete your normal Kubernetes login in another terminal, then reload the
+selected kubeconfig and retry. Press **Ctrl+C** to stop waiting. `Forbidden`
+(HTTP 403) means the current identity is authenticated but lacks permissions and
+is not retried. At minimum attach needs `get`/`list` on `aiperfjobs` (or
+`jobsets`), `list` on `pods`, `create` on `pods/portforward`, and — for the
+last-30-lines tail printed when a job is already `Failed` — `get` on `pods/log`.
+See [RBAC and Security](rbac-security.md) for the full CLI-user role.

+## Spec Fields Reference
+
+### Benchmark Configuration (`spec.benchmark`)
+
+The `benchmark` section mirrors the standard AIPerf YAML config. Any field you use in a local `aiperf profile` run works here.
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `models` | list[string] | Model name(s) served by the endpoint |
+| `endpoint.urls` | list[string] | Inference server URLs |
+| `endpoint.streaming` | bool | Enable streaming responses |
+| `endpoint.type` | string | Endpoint type. The CRD deliberately carries **no** `default:` here so an omitted `type` stays absent and `endpoint.template` can infer `type: template`; Pydantic resolves an otherwise-omitted `type` to `chat` |
+| `datasets` | list | Named dataset configurations (each entry has a `name`) |
+| `phases` | list | Ordered load phases (warmup, profiling, etc.), each with a `name` |
+
+See the [YAML Config Reference](../tutorials/yaml-config.md) for the complete set of benchmark fields.
+
+> **Shorthand siblings.** The apiserver also accepts the singular shortcuts
+> from AIPerf CLI YAML — `model:` (string/list/object), `dataset:` (single
+> dict), and top-level `warmup:` / `profiling:` (phase dicts) — and the
+> operator hoists them into the canonical `models`/`datasets`/`phases`
+> shapes before validation. Mixing the canonical and shorthand form for the
+> same slot (e.g. both `datasets:` and `dataset:`) is rejected at admission.
+> Full rule catalog: [CRD Validation Rules](crd-validation.md).
+
+`datasets` and `phases` are lists, not maps. Kubernetes alphabetizes the keys
+of object-typed CRD fields at storage time, so phase ordering is only
+preserved because it is expressed as a list.
+
+### Plot envelope (`spec.plot`)
+
+Kubernetes preserves the Config-v2 `plot:` envelope field and runs it after
+the benchmark's exporters have finished, before the results-sidecar ready
+marker is written. The resolved envelope is saved as
+`.aiperf-plot-config.yaml` beside the run artifacts, so a later
+`aiperf plot <run-directory>` uses the same visualization configuration.
+
+Setting `plot:` implies `spec.benchmark.artifacts.autoPlot: true` unless
+`autoPlot: false` was explicitly authored. With the default
+`plotRequired: false`, rendering failures produce a warning and the exported
+benchmark artifacts still become ready. With `plotRequired: true`, rendering
+is part of the completion transaction: a failure leaves results unready and
+the controller exits non-zero. Inline plot mappings are the portable form for
+hand-authored CRs; `aiperf kube generate -f config.yaml` resolves a file-backed
+`plot: ./plots/config.yaml` into the inline form when it emits the CR.
+
+### Load Phases (`spec.benchmark.phases`)
+
+Each phase defines a load pattern:
+
+```yaml
+phases:
+  - name: warmup
+    kind: warmup
+    type: concurrency
+    concurrency: 10
+    requests: 10
+  - name: profiling
+    kind: profiling
+    type: concurrency
+    concurrency: 50
+    requests: 500
+```
+
+| Field | Type | Default | Description |
+|-------|------|---------|-------------|
+| `name` | string | required | Unique phase identity used in status and artifact paths. Must match `^[A-Za-z_][A-Za-z0-9_-]*$` and be unique case-insensitively |
+| `kind` | string | inferred for canonical names | Semantic role: `warmup` or `profiling`; warmup metrics are kept phase-scoped and excluded from profiling aggregates |
+| `type` | string | required | Load type: `concurrency`, `constant`, `poisson`, `gamma`, `user_centric`, or `fixed_schedule` |
+| `concurrency` | int | - | Number of concurrent requests (>= 1) |
+| `requests` | int | - | Total requests to send (>= 1) |
+| `duration` | float \| string | - | Phase duration, alternative to `requests`. Seconds, or a suffixed string (`300`, `'5m'`, `'2h'`) |
+| `sessions` | int | - | Stop after this many sessions complete (>= 1) |
+
+### Deployment Options (spec top level)
+
+| Field | Type | Default | Description |
+|-------|------|---------|-------------|
+| `image` | string | Installed chart image (operator) or `nvcr.io/nvidia/aiperf:latest` (direct mode) | AIPerf container image |
+| `imagePullPolicy` | string | - | `Always`, `IfNotPresent`, or `Never` (Helm default: `IfNotPresent`) |
+| `resourceMode` | string | `burstable` | Pod CPU/memory mode. `burstable` (default) sets requests only, no limits (Burstable QoS) so the controller can grow during aggregation without being OOM-killed by cgroup; `guaranteed` keeps requests==limits (Guaranteed QoS); `none` omits CPU/memory requests and limits for both controller and worker pods. |
+| `connectionsPerWorker` | int | 100 | Max concurrent connections per worker process |
+| `ttlSecondsAfterFinished` | int | 300 | Seconds to keep pods after completion |
+| `timeoutSeconds` | int | 0 | Benchmark timeout in seconds (0 = no timeout) |
+| `cancel` | bool | `false` | Set to `true` to cancel a running benchmark |
+| `keepFailedPods` | bool | `false` | Preserve pods on failure for debugging (overrides `ttlSecondsAfterFinished`) |
+| `resultsTtlDays` | int | - | Override operator-level `AIPERF_RESULTS_TTL_DAYS` for this job or sweep archive (1-365) |
+| `skipEndpointCheck` | bool | `false` | Skip the operator-side endpoint reachability probe before deploying |
+| `failurePolicy.onChildFailure` | string | `continue` | `continue` or `abort`. On AIPerfJob governs the single benchmark; on AIPerfSweep whether a failed child aborts the sweep |
+| `failurePolicy.maxFailures` | int | 0 | Hard failure budget for the whole sweep; `0` = unbounded. When >0 the sweep stops scheduling children once `failedRuns >= maxFailures` and ends `Failed` |
+| `schemaVersion` | string | `2.0` | Config-v2 schema version; `2.0` is the only accepted value |
+
+`spec` also carries the remaining Config-v2 envelope fields as siblings of
+`benchmark`: `plot` (below), plus `sweep`, `multiRun`, `variables`,
+`randomSeed`, and `noSweepTable`. `sweep` and multi-run orchestration
+(`multiRun.numRuns > 1` or `multiRun.convergence`) are rejected on `AIPerfJob`
+and required/allowed on `AIPerfSweep` — see
+[CRD Validation Rules](crd-validation.md). `AIPerfSweep` additionally accepts
+`childMetadata` (labels/annotations stamped onto every child `AIPerfJob`).
+
+### Pod Template (`spec.podTemplate`)
+
+Customize the pods that run your benchmark. Every field is optional; typed
+fields are preferred over `extraPodSpec` because preflight checks, env merging,
+and securityContext merging only apply to typed fields.
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `nodeSelector` | map | Node labels to constrain scheduling |
+| `tolerations` | list | Tolerations for tainted nodes |
+| `affinity` | map | K8s `Affinity` (nodeAffinity, podAffinity, podAntiAffinity) |
+| `topologySpreadConstraints` | list | K8s `TopologySpreadConstraint` entries |
+| `imagePullSecrets` | list[object] | Secret references for private registries, K8s `LocalObjectReference` shape: `[{name: my-secret}]` |
+| `env` | list | Extra environment variables (K8s `EnvVar` format) |
+| `volumes` | list | Additional volume definitions |
+| `volumeMounts` | list | Additional volume mounts |
+| `annotations` | map | Extra pod annotations |
+| `labels` | map | Extra pod labels |
+| `serviceAccountName` | string | Custom service account |
+| `containerSecurityContext` | map | SecurityContext applied to every container in the controller and worker pods |
+| `podSecurityContext` | map | Pod-level `PodSecurityContext` (fsGroup, runAsUser, sysctls, ...) |
+| `priorityClassName` | string | Native K8s PriorityClass. Distinct from `scheduling.priorityClass` (Kueue) |
+| `runtimeClassName` | string | K8s RuntimeClass (e.g. `nvidia`, `kata`) |
+| `schedulerName` | string | Alternate scheduler to dispatch the pod to |
+| `hostAliases` | list | Extra `/etc/hosts` entries (`{ip, hostnames}`) |
+| `dnsPolicy` | string | `ClusterFirst`, `ClusterFirstWithHostNet`, `Default`, or `None` |
+| `dnsConfig` | map | K8s `PodDNSConfig`; typically paired with `dnsPolicy: None` |
+| `terminationGracePeriodSeconds` | int | Grace period before SIGKILL (>= 0) |
+| `initContainers` | list | InitContainers run to completion before the main containers |
+| `shareProcessNamespace` | bool | Share a PID namespace across containers (chaos testing; keep `false` in production) |
+| `extraPodSpec` | map | Escape hatch: raw PodSpec keys merged last, overriding the typed fields above |
+
+### Scheduling (`spec.scheduling`)
+
+For clusters using [Kueue](https://kueue.sigs.k8s.io/) for resource management:
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `queueName` | string | Kueue LocalQueue name for gang-scheduling |
+| `priorityClass` | string | Kueue WorkloadPriorityClass for scheduling priority |
+
+---
+
+## CLI Flags
+
+When using `aiperf kube profile`, you can set deployment options via CLI flags. These override values in a config file:
+
+| Flag | Maps To | Default | Description |
+|------|---------|---------|-------------|
+| `--image` | `spec.image` | YAML, installed chart, or direct-mode default | Explicit container-image override; an image authored in workload YAML remains authoritative when this flag is omitted |
+| `--image-pull-policy` | `spec.imagePullPolicy` | - | Image pull policy (Helm default: `IfNotPresent`) |
+| `--total-workers` | `spec.benchmark.runtime.workers` | 10 | Exact worker target (distributed across pods); when omitted, a YAML-authored `runtime.workers` wins before automatic sizing |
+| `--name` | `metadata.name` | auto-generated | Job name (DNS label, max 40 chars) |
+| `--namespace`, `-n` | `metadata.namespace` | kubeconfig context namespace | Target namespace; required when your context does not set one |
+| `--ttl-seconds` | `spec.ttlSecondsAfterFinished` | 300 | TTL after completion |
+| `--node-selector` | `spec.podTemplate.nodeSelector` | `{}` | Node selector labels |
+| `--tolerations` | `spec.podTemplate.tolerations` | `[]` | Pod tolerations |
+| `--queue-name` | `spec.scheduling.queueName` | - | Kueue queue name |
+| `--priority-class` | `spec.scheduling.priorityClass` | - | Kueue priority class |
+| `--image-pull-secrets` | `spec.podTemplate.imagePullSecrets` | `[]` | Pull secret names |
+| `--env-vars` | `spec.podTemplate.env` | `{}` | Non-sensitive extra env vars |
+| `--env-from-secrets` | `spec.podTemplate.env` | `{}` | Env vars from Kubernetes Secrets as `ENV_NAME=secret_name/key`; required for endpoint API keys, sensitive headers, and credentialed URLs |
+| `--secret-mounts` | `spec.podTemplate.volumes` + `volumeMounts` | `[]` | Secret volume mounts (`{name, mount_path, sub_path}`) as a JSON object, a JSON array, or the flag repeated |
+| `--annotations` | `spec.podTemplate.annotations` | `{}` | Extra pod annotations |
+| `--labels` | `spec.podTemplate.labels` | `{}` | Extra pod labels |
+| `--service-account` | `spec.podTemplate.serviceAccountName` | - | Pod service account |
+| `--kubeconfig` | - | `~/.kube/config` or `KUBECONFIG` | Path to kubeconfig file |
+| `--kube-context` | - | current context | Kubernetes context to use |
+| `--detach`, `-d` | - | `false` | Exit after deploying. Auto-enabled in non-interactive environments |
+| `--dry-run` | - | `false` | Print CR without submitting |
+| `--operator` | - | `false` | Deploy through the operator without probing the cluster-scoped AIPerfJob CRD |
+| `--no-operator` | - | `false` | Deploy without operator |
+| `--skip-endpoint-check` | - | `false` | Skip endpoint health check |
+| `--no-wait` | - | `false` | Don't wait for pods ready |
+| `--attach-port` | - | 0 (ephemeral) | Local port for port-forward |
+
+The four map-valued flags — `--annotations`, `--labels`, `--env-vars`, and
+`--env-from-secrets` — each accept three equivalent spellings: `--labels
+tier=gold`, `--labels.tier gold`, and `--labels '{"tier": "gold"}'`. Repeat the
+flag for additional entries.
+
+Benchmark CLI flags use the same precedence for plain AIPerf config files and
+`AIPerfJob` CR input: explicitly passed flags override YAML, while omitted CLI
+defaults do not rewrite authored values. This applies to `profile` and
+`generate`; `kube sweep` applies the same benchmark overrides before it builds
+the `AIPerfSweep` template. Kubernetes deployment flags merge into the CR
+deployment subtree, so, for example, `--node-selector gpu=true` does not erase
+an unrelated YAML `podTemplate.affinity` or `podTemplate.volumes` block. An
+explicit list-valued flag still replaces the corresponding YAML list.
+
+Operator mode is auto-detected when neither mode flag is passed. On a
+multi-tenant cluster where users can create namespaced `AIPerfJob` resources
+but cannot read cluster-scoped CRDs, pass `--operator` explicitly. When an
+explicit `--namespace` is also supplied, `profile` assumes the namespace was
+pre-provisioned and does not attempt to create it. `--operator` and
+`--no-operator` are mutually exclusive.
+
+When an `AIPerfJob` CR is passed to `profile --no-operator` or
+`generate --no-operator`, direct mode preserves the fields that JobSet can
+represent, including `imagePullPolicy`, `resourceMode`, `keepFailedPods`,
+`ttlSecondsAfterFinished`, `podTemplate`, and `scheduling`. The operator still
+owns CR lifecycle fields such as `timeoutSeconds`, `resultsTtlDays`, `cancel`,
+and `failurePolicy`; they have no direct-mode reconciler.
+
+Some benchmark runtime fields are intentionally Kubernetes-managed:
+`artifacts.dir` is fixed to the mounted `/results` volume, and the operator
+sets the service run type, API bind, dataset-service URL, UI, and ZMQ transport
+needed for cross-pod operation. Other runtime fields, including
+`workers`, `workersPerPod`, `recordProcessors`,
+`recordProcessorsPerPod`, and `statsInterval`, remain user-configurable. A
+total `recordProcessors` value must divide evenly across identical worker pods;
+otherwise set `recordProcessorsPerPod` explicitly. These fields also drive the
+preflight memory estimate, so a pod layout you set here is the layout the
+estimate is sized against — see
+[Memory estimator](memory-estimator.md#topology).
+
+---
+
+## Helm Chart Configuration
+
+The operator Helm chart is configured via `values.yaml`. Key settings:
+
+### Operator
+
+```yaml
+operator:
+  replicas: 1
+  id: ""                            # "" = cluster-wide operator; a unique id
+                                    # claims operator.watchNamespaces so the
+                                    # cluster-wide operator steps aside
+  resources:
+    requests: { cpu: 250m, memory: 256Mi }
+    # No limits set by default (burstable QoS) so the operator can scale
+    # memory/CPU with high-concurrency runs.
+  env:
+    monitorInterval: "10.0"         # seconds between status checks
+    monitorInitialDelay: "5.0"      # delay before first status check
+    jobTimeoutSeconds: "0"          # 0 = no timeout
+    podRestartThreshold: "3"        # restarts before warning events
+    resultsTtlDays: "30"            # days to keep results on PVC
+    resultsMaxRetries: "5"          # retries for fetching results
+    resultsRetryDelay: "2.0"        # delay between result fetch retries
+    endpointCheckTimeout: "10.0"    # endpoint health check timeout
+    resultsCompressOnDisk: "true"   # store results as zstd on PVC
+```
+
+`operator.replicas` is fixed at `1`. The kopf process and runs index have one
+authoritative writer and do not use leader election, so the chart rejects
+multi-replica values instead of presenting unsafe pseudo-HA.
+
+`operator.id` decides namespace ownership between installs. Leave it empty for
+the cluster-wide operator. Set it, together with `operator.watchNamespaces`, to
+run a scoped operator that leases those namespaces away from the cluster-wide
+one — see
+[Operator Scope and Namespace Ownership](production.md#operator-scope-and-namespace-ownership).
+
+### Storage
+
+Results are stored on a PVC so they survive pod deletion:
+
+```yaml
+storage:
+  enabled: true           # default — PVC-backed; set false for ephemeral emptyDir
+  size: 1Ti
+  storageClassName: ""    # empty = cluster default
+  mountPath: "/data"      # mount path inside the operator pod
+  accessMode: "ReadWriteOnce"
+  emptyDirSizeLimit: ""   # bounds the fallback emptyDir when enabled=false; empty = unbounded
+```
+
+### Results Server
+
+A sidecar that serves stored results via HTTP (used by `aiperf kube results` by default):
+
+```yaml
+resultsServer:
+  port: 8081
+  resources:
+    requests: { cpu: 100m, memory: 512Mi }
+    limits: { cpu: 500m, memory: 1Gi }
+```
+
+The `resultsServer` chart block only exposes `port` and `resources` today.
+
+The results-server also hosts optional POST routes that create or cancel
+`AIPerfJob` resources. These are governed by two environment variables read on
+the results-server container: `AIPERF_OPERATOR_MUTATING_ROUTES_ENABLED`
+(default `false`) and `AIPERF_OPERATOR_MUTATING_ROUTES_TOKEN` (default empty —
+fails closed). When disabled, the read-only APIs stay exposed while those
+mutating POSTs return 403, so serving the results-server does not grant write
+access through the operator ServiceAccount. The index-rebuild route is mounted
+read-only on the results-server, so even with the routes enabled and a valid
+token it returns 503; restart the operator pod to run the single-writer startup
+rebuild.
+
+The bundled chart does **not** template these two variables (there is no `resultsServer.mutatingRoutes` value and no token-secret projection). To turn the routes on, set both env vars directly on the `results-server` container — e.g. via a deployment patch or a customized chart template — then have clients send `Authorization: Bearer <token>` on protected POST requests. The browser dashboard never receives this token and keeps create/cancel controls disabled; use `aiperf kube` or `kubectl` from an authenticated terminal for those mutations.
+
+### `dashboard`
+
+Optional Plotly Dash sidecar for the operator Pod. Default off.
+
+| Key                              | Default      | Description                                                                   |
+|----------------------------------|--------------|-------------------------------------------------------------------------------|
+| `dashboard.enabled`              | `false`      | Whether to add the dashboard container and surface the "Plots ↗" SPA link.   |
+| `dashboard.port`                 | `8082`       | Pod-local HTTP port. `results-server` reverse-proxies `/dashboard/*` here.    |
+| `dashboard.resources.requests`   | `cpu: 100m, memory: 1Gi` | Resource requests. Leave generous so the build has memory.        |
+| `dashboard.resources.limits`     | `{}`         | Empty by default = no limit. Set `memory:` to enforce a ceiling.             |
+
+See [`dashboard-ui.md`](dashboard-ui.md#isolated-plotly-dashboard-sidecar-opt-in) for the full architecture.
+
+### Benchmark RBAC Namespaces
+
+```yaml
+benchmarkRbacNamespaces: []
+```
+
+The benchmark `Role` and `RoleBinding` are installed in the chart's release
+namespace whenever `rbac.create` is `true` (the default). List additional
+namespaces in `benchmarkRbacNamespaces` to install the same pair there — for
+example when each team runs benchmarks in its own namespace. The chart does
+not create any of these namespaces; they must already exist.
+
+### Operator ServiceAccount
+
+```yaml
+serviceAccount:
+  create: true
+  name: "" # auto-generated from the release name when create=true
+  annotations: {}
+```
+
+With `create: false` the chart provisions no ServiceAccount and no RBAC of its
+own, so `serviceAccount.name` is **required** and must name a pre-provisioned
+account already bound to the operator's `ClusterRole`. Omitting it fails the
+render; it does not fall back to the namespace `default` account, which carries
+none of the operator's permissions. See
+[`rbac-security.md`](rbac-security.md#rbaccreatefalse-workflow) for the
+out-of-band RBAC tree.
+
+### Default Image
+
+The default image used for benchmark jobs if not specified in the CR:
+
+```yaml
+defaults:
+  image: "" # empty = "<image.repository>:<image.tag|Chart.AppVersion>"
+  imagePullPolicy: "IfNotPresent"
+```
+
+When `defaults.image` is empty (the chart default), the chart computes the
+benchmark image as `<image.repository>:<image.tag | Chart.AppVersion>`, so
+overriding `image.tag` automatically propagates to benchmark pods. Set
+`defaults.image` explicitly to decouple the benchmark image from the operator
+image.
+
+### Ingress
+
+Expose the results-server HTTP API outside the cluster via a Kubernetes `Ingress`. Disabled by default -- results are reachable via `ClusterIP` + `kubectl port-forward`.
+
+```yaml
+ingress:
+  enabled: false
+  className: ""                    # IngressClass name (e.g. "nginx"); empty uses cluster default
+  annotations: {}                  # annotations applied to the Ingress
+  hosts:
+    - host: aiperf.example.com
+      paths:
+        - path: /
+          pathType: Prefix         # backend port defaults to resultsServer.port; override with portNumber
+  tls: []                          # optional list of {hosts, secretName}
+```
+
+### NetworkPolicy
+
+Restrict pod traffic to/from the operator. Disabled by default -- no restrictions applied. When enabled, ingress is allowed from the release namespace, the benchmark namespace, `benchmarkRbacNamespaces`, and `allowedNamespaces` on the health (8080), results (`resultsServer.port`), and metrics (`operator.metrics.port`, when non-zero) ports. Egress allows DNS, the K8s API server (443/6443), the benchmark namespace, `benchmarkRbacNamespaces`, and `allowedNamespaces`.
+
+```yaml
+networkPolicy:
+  enabled: false
+  allowedNamespaces: []            # extra namespaces allowed to reach the operator and reachable on egress
+  allowedIngressCIDRs: []          # CIDR allow-list for external scrapers (Prometheus, ingress controllers)
+```
+
+### Kueue
+
+```yaml
+kueue:
+  # When set, the benchmark namespace is annotated with
+  # kueue.x-k8s.io/default-queue-name so all AIPerf jobs are admitted through
+  # Kueue even without an explicit --queue-name flag. Left empty, it falls
+  # back to kueue.localQueueName when createQueues is true.
+  defaultQueueName: ""
+
+  # Optionally let the chart provision the Kueue objects themselves
+  # (ResourceFlavor + ClusterQueue + LocalQueue). Off by default so the
+  # chart renders on clusters without Kueue CRDs.
+  createQueues: false
+  flavorName: "default-flavor"
+  clusterQueueName: "aiperf-cluster-queue"
+  localQueueName: "aiperf-local-queue"
+  resources:
+    cpu: "1000"
+    memory: "4Ti"
+    gpu: ""            # empty = omit nvidia.com/gpu from the quota entirely
+```
+
+See [Kueue Integration](kueue.md) for the full gang-scheduling walkthrough.
+
+### `helm test` hooks
+
+```yaml
+tests:
+  # Renders the two `helm test` hook Pods (CRD check, operator health check)
+  # and the dedicated ServiceAccount / Role / RoleBinding / ClusterRole /
+  # ClusterRoleBinding they run under. All five RBAC objects and both Pods are
+  # gated together, so disabling this never leaves a Pod pointing at a
+  # ServiceAccount that was not created.
+  enabled: true
+```
+
+Set `tests.enabled=false` when cluster policy forbids chart-managed
+cluster-scoped RBAC. `test-crd-installed` reads cluster-scoped
+CustomResourceDefinitions, so its `ClusterRole` cannot be narrowed to a
+namespace — this is the only way to make the chart emit zero `ClusterRole` and
+`ClusterRoleBinding` objects. `helm test` then prints `TEST SUITE: None` and
+exits 0. It is a separate flag from `rbac.create` on purpose; see
+[Eliminating all cluster-scoped RBAC](rbac-security.md#eliminating-all-cluster-scoped-rbac).
+
+---
+
+## Configuration Patterns
+
+### Combining CLI Flags with Config Files
+
+CLI flags override config file values. This is useful for changing deployment settings without editing the YAML:
+
+```bash
+# Use config file for benchmark settings, override image and workers
+aiperf kube profile \
+  --config benchmark.yaml \
+  --image my-registry/aiperf:v2.0 \
+  --total-workers 20 \
+  --namespace production
+```
+
+### Validating Before Deploying
+
+`aiperf kube validate` checks `AIPerfJob` and `AIPerfSweep` CR YAML — files
+with `apiVersion: aiperf.nvidia.com/v1alpha1`, a `kind:`, `metadata.name`, and
+`spec.benchmark`. A plain benchmark config file is not a CR and will fail these
+structural checks; generate a CR first with
+`aiperf kube generate --operator --config benchmark.yaml`.
+
+```bash
+# Validate CR structure and fields
+aiperf kube validate aiperfjob.yaml
+
+# Strict mode fails on unknown spec fields
+aiperf kube validate --strict aiperfjob.yaml
+
+# JSON output for CI
+aiperf kube validate -o json aiperfjob.yaml
+```
+
+Preview what will be submitted without deploying:
+
+```bash
+aiperf kube profile --config benchmark.yaml --image aiperf:latest --dry-run
+```
+
+### Memory Estimation
+
+AIPerf prints a memory estimate before deploying. This helps you right-size your pods:
+
+```bash
+aiperf kube generate --operator --config benchmark.yaml --image aiperf:latest
+```
+
+The memory estimate is printed to stderr. It accounts for dataset size, number of workers, connection pools, and record buffers.
+
+### Multiple Phases
+
+Use multiple phases to warm up before measuring:
+
+```yaml
+phases:
+  - name: warmup
+    kind: warmup
+    type: concurrency
+    concurrency: 10
+    requests: 20
+  - name: low_load
+    kind: profiling
+    type: concurrency
+    concurrency: 25
+    requests: 250
+  - name: high_load
+    kind: profiling
+    type: concurrency
+    concurrency: 100
+    requests: 500
+```
+
+Phases run in order. Every phase keeps phase-scoped results; only phases with
+`kind: profiling` contribute to profiling aggregates. Canonical names
+`warmup` and `profiling` infer their matching kinds, while custom names require
+an explicit `kind`.
+
+---
+
+## Resource Mode
+
+`spec.resourceMode` controls the QoS class Kubernetes assigns to benchmark pods. The three modes differ only in how `requests` and `limits` are emitted onto the manifest — the underlying resource budget is the same in every case.
+
+| Mode | Behavior | K8s QoS class | When to use |
+|---|---|---|---|
+| `burstable` (default) | `requests` only; no `limits`. | Burstable | Default. Cost-sensitive clusters, development, and any benchmark where the controller's aggregation phase may temporarily allocate beyond the request — limits-free pods are not OOM-killed by cgroup. Controller pods stay Burstable by default in the operator's own `values.yaml` for the same reason. |
+| `guaranteed` | `requests == limits` for CPU and memory. | Guaranteed | Production benchmarks where pods must not be evicted under pressure and noisy-neighbor behavior is unacceptable. Use this mode when you have measured the controller's peak memory and want a hard ceiling. |
+| `none` | Neither `requests` nor `limits`. | BestEffort | Environments where CPU/memory admission control is disabled (e.g. CI `kind` clusters with tight node budgets, or when an external scheduler handles admission). The resource-dependent preflight checks ("Node Resources", "Per-Node Schedulability", "Resource Quotas", "Memory Estimation") are auto-skipped. |
+
+The mode applies to both controller-pod and worker-pod containers; there is no per-container override. On an `AIPerfSweep` it also covers the sweep-controller pod (both its `sweep-controller` and `results-sidecar` containers), which is why `burstable` matters there: under `sweep.type: adaptive_search` that pod imports torch/BoTorch and grows to roughly 350 MiB after the first GP fit, well past its 512Mi request. OOMKill semantics follow the QoS class — `guaranteed` pods will not be evicted for resource pressure, `burstable` pods may be throttled, and `none`/BestEffort pods can be evicted first.
+
+---
+
+## Tunable Environment Variables (`AIPERF_K8S_*`)
+
+These variables tune the operator and individual benchmark pods. `operator.env` is a fixed key map, not an arbitrary passthrough: only the keys it declares reach the container. For any other variable, set it on the live Deployment (`kubectl -n aiperf-system set env deployment/aiperf-operator -c operator KEY=VALUE` — `-c operator` matters, the Deployment also runs the `results-server` and `dashboard` containers) to affect every subsequent job, or use `spec.podTemplate.env` to affect one CR only.
+
+Resource-sizing and JobSet variables are read by the process that *renders* the JobSet, so `spec.podTemplate.env` has no effect on them; they must be set on the operator.
+
+### Resource sizing (per-container CPU / memory)
+
+Every control-plane container, the event-bus proxy sidecar, the results sidecar, and the worker pod have a paired `_CPU` / `_MEMORY` variable. Defaults are low burstable requests so many tiny jobs can start concurrently; raise them for very large concurrency or high-token workloads.
+
+| Variable | Default | Applies to |
+|---|---|---|
+| `AIPERF_K8S_SYSTEM_CONTROLLER_CPU` / `_MEMORY` | `75m` / `192Mi` | SystemController container |
+| `AIPERF_K8S_SWEEP_CONTROLLER_CPU` / `_MEMORY` | `75m` / `512Mi` | Sweep-controller container (higher memory: adaptive search imports torch/BoTorch here) |
+| `AIPERF_K8S_TIMING_MANAGER_CPU` / `_MEMORY` | `50m` / `192Mi` | TimingManager container |
+| `AIPERF_K8S_DATASET_MANAGER_CPU` / `_MEMORY` | `50m` / `256Mi` | DatasetManager container |
+| `AIPERF_K8S_RECORDS_MANAGER_CPU` / `_MEMORY` | `75m` / `256Mi` | RecordsManager container (raise to 4000m+ for >500k concurrency) |
+| `AIPERF_K8S_API_CPU` / `_MEMORY` | `75m` / `256Mi` | API container (WebSocket + HTTP) |
+| `AIPERF_K8S_GPU_TELEMETRY_MANAGER_CPU` / `_MEMORY` | `25m` / `192Mi` | GPU telemetry container |
+| `AIPERF_K8S_SERVER_METRICS_MANAGER_CPU` / `_MEMORY` | `25m` / `192Mi` | Server-metrics container |
+| `AIPERF_K8S_RESULTS_SIDECAR_CPU` / `_MEMORY` | `25m` / `192Mi` | Results sidecar (fallback retrieval path) |
+| `AIPERF_K8S_EVENT_BUS_PROXY_CPU` / `_MEMORY` | `50m` / `64Mi` | Event-bus XPUB/XSUB proxy sidecar |
+| `AIPERF_K8S_WORKER_POD_CPU` / `_MEMORY` | `3350m` / `6Gi` | Worker pod (workers + record processors + WPM) |
+
+### Architecture toggles
+
+| Variable | Default | Purpose |
+|---|---|---|
+| `AIPERF_K8S_EVENT_BUS_SIDECAR_ENABLED` | `true` | Run the XPUB/XSUB event-bus proxy as a dedicated sidecar container. Set to `false` to revert to the pre-sidecar behavior where `SystemController` hosts the proxy in-process. Only disable if you are explicitly testing the legacy path. |
+| `AIPERF_K8S_RECORD_PROCESSOR_SCALE_FACTOR` | `1` | Workers per record processor inside each worker pod. `1` means one RP per worker (maximum fairness); higher values amortize RP overhead across more workers. |
+| `AIPERF_K8S_RECORD_PROCESSOR_CPU_REQUEST` | (unset) | Optional per-RP CPU request override. When unset, RP CPU is derived from the worker-pod budget. |
+
+### JobSet and lifecycle
+
+| Variable | Default | Purpose |
+|---|---|---|
+| `AIPERF_K8S_JOBSET_TTL_SECONDS_AFTER_FINISHED` | `300` | Seconds to keep pods after JobSet completion. Override per-CR via `spec.ttlSecondsAfterFinished`. |
+| `AIPERF_K8S_JOBSET_DIRECT_MODE_TTL_SECONDS` | `28800` (8h) | TTL applied when `--no-operator` is used, giving you time to pull results from pod-local storage. |
+| `AIPERF_K8S_JOBSET_CONTROLLER_BACKOFF_LIMIT` | `0` | Controller-job retry count. Default `0` — fail fast when the controller crashes. |
+| `AIPERF_K8S_JOBSET_WORKER_BACKOFF_LIMIT` | `20` | Worker-job retry count. Higher than controller to absorb transient pod-startup flakes. |
+| `AIPERF_K8S_JOBSET_WORKER_CONNECTION_PROBE_TIMEOUT` | `60.0` | Seconds a worker waits for the PUB/SUB connection probe before exiting so K8s restarts it. |
+
+### Health probes
+
+| Variable | Default | Purpose |
+|---|---|---|
+| `AIPERF_K8S_HEALTH_STARTUP_PERIOD_SECONDS` | `5` | Startup probe interval. |
+| `AIPERF_K8S_HEALTH_STARTUP_FAILURE_THRESHOLD` | `30` | Consecutive failures before the container is killed during startup. Raise for slow-starting workloads (large tokenizers, cold container images). |
+| Other `AIPERF_K8S_HEALTH_*` | see code | Liveness/readiness intervals, timeouts, thresholds. |
+
+### Ports
+
+All health and service ports are overridable via `AIPERF_K8S_PORT_*` (e.g. `AIPERF_K8S_PORT_API_SERVICE=9090`, `AIPERF_K8S_PORT_RESULTS_SIDECAR=9091`, `AIPERF_K8S_PORT_SYSTEM_CONTROLLER_HEALTH=8080`). Consult `src/aiperf/kubernetes/environment.py::_PortSettings` for the full list — changing these is rarely necessary.
+
+The complete, generated reference for every `AIPERF_*` variable (including non-k8s ones) lives in [`../environment-variables.md`](../environment-variables.md).

+
+# CRD Validation Rules
+
+When you `kubectl apply` an `AIPerfJob` or `AIPerfSweep` CR, the Kubernetes
+apiserver runs two layers of validation **before** the operator ever sees the
+resource:
+
+1. **Structural schema** — types, enums, `minimum`/`maximum`, `required`. If
+   this layer rejects, the resource is never persisted.
+2. **CEL `x-kubernetes-validations`** — cross-field invariants compiled into
+   the CRD. These mirror the Pydantic `@model_validator` rules on the
+   underlying config models (`EndpointConfig`, `RuntimeConfig`,
+   `MultiRunConfig`) and on `AIPerfJobSpec` / `AIPerfSweepSpec`, but fire at
+   admission time so a bad CR is rejected with a clear message before any pod
+   is scheduled.
+
+The CRD that defines both layers is auto-generated from the `AIPerfJobSpec` and
+`AIPerfSweepSpec` Pydantic models in `src/aiperf/kubernetes/crd_models.py` —
+see [the dev flow doc](../dev/kubernetes-flow.md#crd-generator)
+for how to add new rules.
+
+The lifecycle fields `spec.cancel` and `spec.skipEndpointCheck` are native
+booleans, and `spec.ttlSecondsAfterFinished` is a nonnegative integer. Quoted
+forms such as `cancel: "false"` or `ttlSecondsAfterFinished: "300"` are rejected
+at admission. Cancellation and retention handlers consume raw Kubernetes spec
+values, so native schema typing is part of the lifecycle safety boundary.
+
+## Shorthand acceptance
+
+The whole structural `required` chain is `spec: [benchmark]`,
+`spec.benchmark: [endpoint]`, `endpoint: [urls]`, and `spec.benchmark` carries
+an **empty** `x-kubernetes-validations: []` block. `models` and every
+shorthand sibling (`model`, `dataset`, `warmup`, `profiling`) are typeless
+`x-kubernetes-preserve-unknown-fields` properties; `datasets` and `phases` are
+`type: array` with opaque preserve-unknown items (`datasets` additionally
+carries `minItems: 1` / `maxItems: 1` because the runtime loads exactly one
+dataset, `phases` carries `minItems: 1`). No CEL rule requires or excludes any
+of them: a typeless field cannot be `has()`-ed and opaque array items cannot be
+dereferenced. So the apiserver accepts either idiom, and the operator's
+before-validator does the actual shorthand↔canonical normalization on
+reconcile. This means **kubectl apply accepts the CLI-YAML idiom** without
+rewriting:
+
+```yaml
+# Shorthand form — accepted by the apiserver, normalized by the operator's
+# before-validator on reconcile.
+spec:
+  benchmark:
+    endpoint:
+      urls: ["http://server:8000/v1/chat/completions"]
+      type: chat
+    model: meta-llama/Llama-3.1-8B-Instruct  # singular, scalar
+    dataset:                                 # singular, dict
+      type: synthetic
+    profiling:                               # phase shorthand
+      type: concurrency
+```
+
+```yaml
+# Canonical form — also accepted; same post-normalization shape, except that
+# the `dataset:` shorthand above injects `name: default` rather than `main`.
+spec:
+  benchmark:
+    endpoint:
+      urls: ["http://server:8000/v1/chat/completions"]
+      type: chat
+    models: [meta-llama/Llama-3.1-8B-Instruct]
+    datasets:
+    - name: main
+      type: synthetic
+    phases:
+    - name: profiling
+      type: concurrency
+```
+
+One more node is deliberately typeless for the same reason:
+`spec.benchmark.artifacts.userFiles[].content`. A user file's body is a bare
+string for `format: text` and a dict/list/scalar otherwise, so no single
+`type:` matches every legal value. The node carries
+`x-kubernetes-preserve-unknown-fields: true` with no `type`, and the
+format↔content pairing is enforced by the `UserFile` Pydantic validators on
+reconcile. `path` and `content` stay structurally `required`.
+
+You **cannot** mix the two forms for the same slot — the operator's
+`normalize_before_validation` raises a Pydantic ``ValueError`` on reconcile
+(`status.phase=Failed` with `'dataset' cannot be used with 'datasets'. Use
+'dataset' for a single dataset or 'datasets' for multiple named datasets.`).
+The check can't move to CEL because the shorthand fields are typeless
+preserve-unknown siblings — see
+[Operator-side (Pydantic) invariants](#operator-side-pydantic-invariants) below.
+
+## Rule catalog
+
+The tables below list **only the CEL rules `tools/generate_crd.py` actually
+emits** (verified against the generated `crd-aiperfjob.yaml` /
+`crd-aiperfsweep.yaml`). Each entry gives the verbatim CEL expression and the
+message users see on rejection. Cross-field invariants that CEL cannot express
+are enforced by Pydantic on the operator side instead — see
+[Operator-side (Pydantic) invariants](#operator-side-pydantic-invariants) below.
+
+### Endpoint rules — `spec.benchmark.endpoint` (both kinds)
+
+| CEL rule | Message |
+|---|---|
+| `!has(self.type) \|\| self.type != 'template' \|\| has(self.template)` | `endpoint.template is required when endpoint.type='template'` |
+| `!has(self.template) \|\| !has(self.type) \|\| self.type == 'template'` | `endpoint.template is only used when endpoint.type='template' (omit type to have it inferred)` |
+| `!has(self.requestContentType) \|\| self.requestContentType != 'multipart/form-data' \|\| !has(self.type) \|\| self.type in ['audio_transcription', 'image_edit', 'video_generation']` | `requestContentType='multipart/form-data' is only supported on endpoint types that accept form data: audio_transcription, image_edit, video_generation` |
+| `!has(self.path) \|\| self.path.startsWith('/')` | `endpoint.path must start with '/' (e.g. '/v1/chat/completions', not 'v1/chat/completions')` |
+
+The form-data endpoint list in the third rule is derived at generation time
+from the `requires_form_data` plugin metadata in
+`src/aiperf/plugin/plugins.yaml`, so it cannot drift from the Pydantic gate.
+
+### Runtime rules — `spec.benchmark.runtime` (both kinds)
+
+| CEL rule | Message |
+|---|---|
+| `!has(self.apiHost) \|\| has(self.apiPort)` | `runtime.apiHost requires runtime.apiPort to be set` |
+| `!has(self.workersMin) \|\| !has(self.workers) \|\| int(self.workersMin) <= int(self.workers)` | `runtime.workersMin must be <= runtime.workers` |
+
+### MultiRun rules — `spec.multiRun` (both kinds)
+
+| CEL rule | Message |
+|---|---|
+| `!has(self.convergence) \|\| !has(self.convergence.minRuns) \|\| !has(self.numRuns) \|\| self.convergence.minRuns <= self.numRuns` | `multiRun.convergence.minRuns must be <= multiRun.numRuns; either lower minRuns or raise numRuns` |
+
+> No CEL rule is attached to `spec.benchmark.artifacts` on either kind.
+
+### AIPerfJob spec-level rules
+
+| CEL rule | Path | Message |
+|---|---|---|
+| `!has(self.sweep)` | `spec` | `AIPerfJob.spec.sweep must be null/omitted. Use kind: AIPerfSweep for parameter sweeps.` |
+| `!has(self.multiRun) \|\| ((!has(self.multiRun.numRuns) \|\| self.multiRun.numRuns <= 1) && !has(self.multiRun.convergence))` | `spec` | `AIPerfJob.spec.multiRun must describe one run without convergence. Use kind: AIPerfSweep for multi-run orchestration.` |
+
+### AIPerfSweep spec-level rules
+
+| CEL rule | Path | Message |
+|---|---|---|
+| `has(self.sweep)` | `spec` | `AIPerfSweep.spec.sweep is required. Use kind: AIPerfJob for single benchmarks.` |
+
+### Workload update rules
+
+Create-time workload fields use this presence-safe transition rule on the
+parent `spec` node:
+
+| CEL rule template | Path | Message template |
+|---|---|---|
+| `has(oldSelf.<field>) == has(self.<field>) && (!has(self.<field>) \|\| oldSelf.<field> == self.<field>)` | `spec` | `spec.<field> is immutable after creation; create a new <kind> to change it` |
+
+Keeping the rule on `spec`, which exists on every update, is intentional.
+A transition rule attached to an optional field is not evaluated when that
+field is added or removed. The explicit `has` parity rejects a value change,
+first-set-after-create, and removal. Kubernetes evaluates rules using
+`oldSelf` only on updates, so initial creation remains unrestricted.
+
+The exact update contract is:
+
+| Kind | Mutable after creation | Immutable after creation |
+|---|---|---|
+| `AIPerfJob` | `cancel`, `timeoutSeconds` | `image`, `imagePullPolicy`, `resourceMode`, `connectionsPerWorker`, `ttlSecondsAfterFinished`, `resultsTtlDays`, `keepFailedPods`, `podTemplate`, `scheduling`, `schemaVersion`, `benchmark`, `sweep`, `multiRun`, `plot`, `variables`, `randomSeed`, `noSweepTable`, `skipEndpointCheck`, `failurePolicy` |
+| `AIPerfSweep` | `cancel`, `ttlSecondsAfterFinished` | `image`, `imagePullPolicy`, `resourceMode`, `connectionsPerWorker`, `timeoutSeconds`, `resultsTtlDays`, `keepFailedPods`, `podTemplate`, `scheduling`, `schemaVersion`, `benchmark`, `sweep`, `multiRun`, `plot`, `variables`, `randomSeed`, `noSweepTable`, `skipEndpointCheck`, `failurePolicy`, `childMetadata` |
+
+The mutable whitelist follows the live reconciliation paths. The AIPerfJob
+monitor rereads `timeoutSeconds`; both kinds watch or poll `cancel`; and the
+operator's parent-sweep reaper rereads `ttlSecondsAfterFinished`. Every other
+field is rendered into the ConfigMap, JobSet, serialized sweep plan, or child
+template during creation. Accepting updates to those fields would change the
+CR without changing the running workload and could make
+`status.observedGeneration` falsely acknowledge a configuration the pods never
+received.
+
+> The `spec.sweep` absence rule is **AIPerfJob-only**; the AIPerfSweep CRD
+> instead asserts `spec.sweep` is present. `spec.benchmark` carries an empty
+> `x-kubernetes-validations: []` on both kinds.
+
+## Operator-side (Pydantic) invariants
+
+Several cross-field invariants **cannot** be expressed in CEL — either the
+fields they reference are typeless preserve-unknown siblings (`model`,
+`dataset`, `warmup`, `profiling`), or the `phases[]` / `datasets[]` array items
+are emitted as opaque `x-kubernetes-preserve-unknown-fields` blobs (they are
+heterogeneous Pydantic discriminated unions). CEL `has(self.X)` won't compile
+against a typeless field, and opaque array items cannot be dereferenced. These
+checks stay in the operator's `@model_validator` decorators and surface only on
+reconcile (they are also run client-side by `aiperf kube validate`):
+
+| Python validator (`src/aiperf/config/config.py` unless noted) | What it enforces |
+|---|---|
+| `normalize_before_validation` (via `normalizers._check_mutual_exclusivity`) | shorthand↔canonical mutual exclusion (`model`/`models`, `dataset`/`datasets`, `warmup`+`profiling`/`phases`), plus `warmup` without `profiling` |
+| `parse_phases` | `phases` must already be a list by validation time (the dict shape is rejected with a migration pointer) |
+| `parse_datasets` → `parse_datasets_input` (`loader/normalizers.py`) | each `datasets[]` entry is a mapping with a required `name` |
+| `validate_phase_names_unique` | duplicate phase names within `phases` |
+| `validate_profiling_phase_required` | at least one non-warmup profiling phase |
+| `validate_seamless_not_on_first_phase` | first phase may not set `seamless=true` |
+| `validate_phase_dataset_compatibility` | each phase is compatible with its resolved dataset |
+| `validate_prefill_requires_streaming` | a phase with `prefill_concurrency` requires `endpoint.streaming=true` |
+| `validate_sweep_no_dashboard_ui` | `sweep` set ⇒ `runtime.ui` is not `dashboard` |
+| `_apply_consistent_seed_default` | auto-fills a consistent random seed for cross-trial sweeps when none is given |
+| `_validate_image_non_empty` (`kubernetes/crd_models.py`) | `spec.image` is non-blank (the CRD also enforces `minLength: 1`, but that accepts `" "`) |
+| `_reject_orchestration_on_aiperfjob` (`kubernetes/crd_models.py`) | AIPerfJob rejects sweep and multi-run orchestration (mirrors its two kind-specific CEL rules) |
+| `_require_sweep_on_aiperfsweep` (`kubernetes/crd_models.py`) | AIPerfSweep requires a `sweep` block (mirrors the `has(self.sweep)` CEL rule) |
+| `_reject_non_finite_sweep_knobs` (`kubernetes/crd_models.py`) | rejects NaN/inf on `sweep.cooldownSeconds`, `sweep.plateauThreshold`, `sweep.slaWarmupSeconds` |
+| `_reject_repeated_iteration_with_convergence` (`kubernetes/crd_models.py`) | AIPerfSweep rejects `sweep.iterationOrder='repeated'` together with `multiRun.convergence` |
+| `_resolve_format` / `_validate_path` (`config/user_files.py`) | `artifacts.userFiles[]` format↔content pairing (`text` needs a string, `json`/`yaml` need structured content) and path safety (relative, no `..`, no control chars) — `content` is typeless in the CRD so CEL cannot type-check it |
+
+> There is no `validate_datasets_unique_names` or `validate_dataset_references`
+> validator — dataset-name presence is checked by `parse_datasets_input` and
+> phase↔dataset coupling by `validate_phase_dataset_compatibility`.
+
+If you submit a CR that the apiserver accepts but the operator later rejects,
+the failure shows up as `status.phase=Failed` with the validation error in
+`status.error` (or in operator pod logs).
+
+## Example error messages
+
+Each CEL rejection names the rule that fired, so the failure points directly
+at what to fix.
+
+```text
+$ kubectl apply -f bad-template.yaml
+The AIPerfJob "x" is invalid: spec.benchmark.endpoint: Invalid value: "object":
+  endpoint.template is required when endpoint.type='template'
+
+$ kubectl apply -f sweep-as-job.yaml
+The AIPerfJob "x" is invalid: spec: Invalid value: "object":
+  AIPerfJob.spec.sweep must be null/omitted. Use kind: AIPerfSweep for
+  parameter sweeps.
+
+$ kubectl apply -f job-as-sweep.yaml
+The AIPerfSweep "x" is invalid: spec: Invalid value: "object":
+  AIPerfSweep.spec.sweep is required. Use kind: AIPerfJob for single
+  benchmarks.
+```
+
+The shorthand↔canonical mutual-exclusion error is **not** a CEL rejection at
+`kubectl apply`; it surfaces on reconcile as `status.phase=Failed` with the
+Pydantic message `'dataset' cannot be used with 'datasets'. Use 'dataset' for
+a single dataset or 'datasets' for multiple named datasets.`
+
+## Extending the rule set
+
+Adding a new CEL rule is a small change in `tools/generate_crd.py`:
+
+1. Decide which **shape** the rule applies to (benchmark, endpoint, runtime,
+   multiRun) and pick the matching `_decorate_*_node` helper, or add a new
+   shape detector if your target node has a unique property fingerprint.
+2. Append a `{"rule": ..., "message": ...}` entry to that helper's
+   `_add_validation_rules(...)` call.
+3. Add a structural assertion to
+   `tests/unit/operator/test_aiperfsweep_crd_generation.py`.
+
+   A shape detector keys off property names, so **renaming a field silently
+   retires every rule attached to its node** — the detector stops matching and
+   the generator reports nothing. Two decorators had been inert this way. When
+   you rename or nest a spec field, re-read the detector that fingerprints it,
+   and prefer a structural test that asserts the rule is present on both kinds
+   over one that only asserts a rule's text.
+4. Regenerate (`uv run python tools/generate_crd.py`) and verify the regen
+   is idempotent (`tools/generate_crd.py --check`).
+5. Round-trip against a real apiserver (kind cluster + `kubectl apply
+   --dry-run=server`) — the CEL compiler runs at CRD-install time and will
+   reject rules that reference undeclared fields or opaque items.
+
+CEL constraints that aren't obvious from the Pydantic side:
+
+- `has(self.X)` only works on properties that are **declared** in the
+  schema. Properties under `x-kubernetes-preserve-unknown-fields` are
+  invisible to CEL.
+- Array items emitted as opaque preserve-unknown blobs cannot be
+  dereferenced (no `phases[].name`, no `phases[0].seamless`).
+- `oldSelf` is only available in transition rules and triggers on update.
+  Use `!has(oldSelf.X) || oldSelf.X == self.X` for "first-set freezes"
+  semantics.
+- The K8s apiserver compiles CEL at CRD install time; rule errors fail
+  the install with a clear `compilation failed: undefined field 'X'`
+  message.

+share port **8081** inside the cluster. `results_server.py` mounts
+`StaticFiles(directory=<operator>/ui, html=True)` at `/` after every API router,
+so `/` serves `index.html` and every sibling asset resolves by filename. Client
+routes are hash-based (`#/jobs/...`), so the browser only ever requests `/` —
+there is no server-side SPA fallback, and an unknown *file* path returns `404`
+rather than `index.html`.
+
+### Recommended: `aiperf kube dashboard`
+
+```bash
+aiperf kube dashboard
+```
+
+This command locates the operator pod, opens a `kubectl port-forward` directly
+to that pod on the results server port (`RESULTS_SERVER_PORT`, default `8081`,
+overridable with `AIPERF_RESULTS_SERVER_PORT`), and launches your default
+browser at the forwarded URL. The port-forward stays open until you press
+`Ctrl+C`, auto-reconnecting with backoff in between.
+
+Useful flags:
+
+| Flag | Purpose |
+|---|---|
+| `--port 8081` | Bind to a specific local port (default: ephemeral). |
+| `--no-browser` | Print the URL instead of opening a browser — useful in SSH sessions. |
+| `--operator-namespace aiperf-system` | Override the namespace to look in. |
+
+### Manual port-forward (enterprise clusters)
+
+If your cluster policy forbids the `aiperf` CLI from spawning `kubectl`, or you
+want a long-lived forward managed by your own tooling, forward the Service
+directly:
+
+```bash
+kubectl port-forward -n aiperf-system svc/aiperf-operator 8081:results
+# open http://localhost:8081
+```
+
+The Service name is whatever Helm's `aiperf-operator.fullname` template
+renders — by default `aiperf-operator`, or `<release>-aiperf-operator` if your
+release name differs from the chart name. The port is exposed under the
+`results` named port (default 8081, see `resultsServer.port` in `values.yaml`).
+
+### Local no-build UI development
+
+For fast iteration on the static operator UI without adding a frontend build
+step, run the local proxy against a forwarded or otherwise reachable operator
+Results API:
+
+```bash
+uv run python tools/operator_ui_proxy.py --dev-reload --port 8123 --upstream http://127.0.0.1:8081
+```
+
+Open `http://127.0.0.1:8123/live/`. The proxy serves
+`src/aiperf/operator/ui/`, forwards `/api/v1/*` to the configured upstream, and
+reloads the browser when `.html`, `.js`, or `.css` files change.
+
+### Authentication
+
+The dashboard inherits the Results API's access model: **no per-user
+authentication** is performed for reads. Access control is the port-forward
+itself — whoever can reach port 8081 inside the cluster (or through a forward)
+can view every job and every result. Do not expose this port via an
+unauthenticated Ingress.
+
+Mutating actions (cancel a run) *are* reachable from the browser, but only
+through the operator's bearer token. `lib/api.js` routes them
+through `mutatingFetch`, which requires a token in `sessionStorage`; the first
+attempt without one raises a `TOKEN_REQUIRED` error, the page opens
+`components/token-modal.js` to collect it, and the action retries. A `401`
+clears the stored token and re-prompts. The token lives only in
+`sessionStorage`, so it is gone when the tab closes and is never persisted to
+disk. If the operator has not set `AIPERF_OPERATOR_MUTATING_ROUTES_ENABLED`, the
+server answers `403` no matter what the browser sends — use `aiperf kube` or
+`kubectl` in that case.
+
+---
+
+## Navigation
+
+The UI is a **flat single-page app** with a text-led horizontal top bar — there
+is no namespace-picker landing page and no per-namespace URL tier. Namespace is
+only ever a path parameter (`:ns`) on a job/sweep detail route or a `?ns=` query
+filter on the list pages; it is never a routing gate, and nothing about the last
+namespace is persisted.
+
+Routes are hash-based, so reloading any page works without server-side route
+configuration. The full route table (`src/aiperf/operator/ui/app.js:52-86`):
+
+| Route | Page | Purpose |
+|---|---|---|
+| `/` | `Dashboard` | Cluster-wide overview: cluster-stats banner, active-jobs cards, throughput-vs-latency scatter, KPI tiles, recent-jobs table. |
+| `/jobs` | `Jobs` | Filterable/sortable table of every AIPerfJob (phase tabs, search, model/endpoint/namespace filters — all synced to the URL query). |
+| `/jobs/:ns/:name` | `JobDetail` | Single-run workbench (see below). |
+| `/jobs/:ns/:name/runs/:epoch` | `JobDetail` | Same workbench pinned to one epoch of a multi-epoch run. |
+| `/sweeps` | `Sweeps` | Filterable/sortable table of every AIPerfSweep. |
+| `/sweeps/:ns/:name` | `SweepDetail` | Sweep workbench (variation curves, Pareto, children). |
+| `/sweeps/:ns/:name/runs/:epoch` | `SweepDetail` | Sweep workbench pinned to one sweep epoch. |
+| `/leaderboard` | `Leaderboard` | Cross-run ranking for a chosen metric. |
+| `/compare` | `Compare` | Multi-run comparison (metric table, bar/Pareto charts). |
+| `/compare/:ns/:name/:epochA/:epochB` | `CompareEpochs` | Two-epoch diff of one run. |
+| `/history` | `History` | A metric's value over time across runs. |
+
+Any other path renders a "Not Found" stub.

+
+### Operator top bar
+
+`TopNav` (`components/top-nav.js`) renders a sticky horizontal bar: the
+`AIPerf Operator` logo and two labelled tab groups on the left, the search
+trigger on the right.
+
+- **OPERATE:** Dashboard, Jobs, Sweeps.
+- **ANALYZE:** Leaderboard, Compare, History.
+
+When `/api/v1/config/features` reports `dashboard_enabled: true`, a third
+(unlabelled) group adds an external **"Plots ↗"** link (see below). NVIDIA green
+is reserved for deliberate actions and live or successful status. The search
+button sits at the right end of the bar and shows its `Ctrl+K` shortcut as a
+`kbd` hint.
+
+### Breadcrumb
+
+Below the top bar, in the workspace chrome, `Breadcrumb`
+(`components/breadcrumb.js`) renders a
+**route-path** breadcrumb derived from the current hash — e.g. `Jobs / <ns> /
+<name> / runs / <epoch>` on a job-epoch route. It is a plain path trail with
+clickable ancestors; there is **no** namespace dropdown or namespace switcher.
+
+### External Plots link
+
+The "Plots ↗" link points at `/dashboard/` — the optional Plotly Dash sidecar.
+The results server mounts an **aiohttp reverse-proxy router**
+(`operator/routers/dashboard_proxy.py`, wired in `results_server.py` right
+before the static-UI mount) that forwards `/dashboard/{path:path}` to the
+dashboard sidecar for GET, POST, PUT, DELETE, PATCH, and OPTIONS. Paths
+containing `.` or `..` segments are rejected with `400` so a decoded traversal
+cannot escape the `/dashboard/` prefix and reach the sidecar's unauthenticated
+`POST /admin/refresh`. The link is gated by
+`/api/v1/config/features`'s `dashboard_enabled` flag, and the proxy returns
+`503` when the sidecar is disabled or unreachable. (The Dash app itself uses
+`WSGIMiddleware` inside the sidecar's own `dashboard_server.py`, not on the
+results server.)
+
+---
+
+## Pages
+
+### Dashboard (`/`)
+
+The cluster-wide landing view (`pages/dashboard.js`).
+
+**What it shows:**
+
+- **Cluster-stats banner** — GPUs used/total + free, utilization %, GPU-node
+  breakdown, and a Kubernetes/cluster tile.
+- **Active-jobs cards** — one card per running/initializing/pending job with a
+  live metric strip (TTFT, output tok/s, P99, ITL, requests, error %) and a
+  progress bar. Click a card to open the workbench.
+- **Throughput-vs-latency scatter** — completed jobs, with TPS/P99, TPS/TTFT,
+  tok-s/P99 axis toggles and a log-scale toggle.
+- **KPI tiles** — Running, Completed, Peak Throughput, Best TTFT, Token
+  Throughput.
+- **Recent-jobs table** — newest completed/failed runs with headline metrics.
+
+**Endpoints consumed:** `GET /api/v1/jobs` (5s), `GET /api/v1/cluster` (10s),
+`GET /api/v1/analytics/scatter` (30s). The scatter poll is a single query that
+replaced the old leaderboard-plus-per-entry-summary fan-out, and it feeds both
+the scatter chart and the KPI tiles.
+
+### Jobs (`/jobs`)
+
+Filterable, sortable table of every AIPerfJob (`pages/jobs.js`). Phase tabs
+(All / Running / Completed / Failed), free-text search, and model / endpoint /
+namespace filters — all persisted to the URL query string. `GET /api/v1/jobs`
+polled every 5s. Clicking a row opens the workbench.
+
+### Job workbench (`/jobs/:ns/:name`)
+
+The deepest page, scoped to one AIPerfJob (`pages/job-detail.js`). Sections
+depend on whether the run is live or finished.
+
+**Always visible:** header (name, phase badge, namespace/model pills, epoch
+selector), conditions, a `PhaseBar` (Phases), record-processing, and a
+`PodsBar` (per-pod JobSet status).
+
+**While running:** a live-throughput line chart, a latency-distribution
+histogram, a realtime KPI grid, and a diagnostics panel (Events / Logs /
+Conditions / Pods tabs). A per-job WebSocket feeds live data. A **Cancel run**
+button is live: clicking it swaps in an inline confirm/keep-running pair, and
+confirming calls `POST /api/v1/jobs/{ns}/{name}/cancel` (prompting for the
+bearer token if none is stored). The button shows a spinner while the patch is
+in flight and stays pending until the next poll moves the phase out of running;
+a failure is reported inline as "Cancel failed: …".
+
+**After completion:** SLA compliance, server metrics, job configuration (with a
+View-YAML modal), run metadata, per-record analysis (from
+`profile_export.jsonl`), concurrency-vs-throughput, latency-percentile and
+latency-timeline charts, ISL distribution, a full metrics-breakdown table, and
+a result-files card.
+
+**Endpoints consumed:** `GET /api/v1/jobs/{ns}/{name}[?epoch=]` (every 3s, or
+8s while the WebSocket is connected, since the socket already carries the live
+numbers), `.../epochs`, `GET /api/v1/config/{ns}/{name}`, and the run-scoped
+file endpoints `GET /api/v1/results/{ns}/{name}/runs/{epoch}` plus the
+per-record and server-metrics artifacts *named by that listing*
+(`per_record_filename` / `server_metrics_filename` — not hardcoded filenames),
+and a per-job WebSocket. The non-epoch results endpoint is deliberately never
+called: until the route is pinned to `/runs/<epoch>`, the artifact cards render
+as unavailable.
+
+### Job epoch view (`/jobs/:ns/:name/runs/:epoch`)
+
+The same workbench pinned to a specific epoch of a multi-epoch run
+(concurrency/request-rate sweeps). Header widgets walk epochs and update the
+URL; a no-epoch URL auto-redirects to the resolved current epoch.
+
+### Sweeps (`/sweeps`)
+
+Filterable, sortable table of every AIPerfSweep (`pages/sweeps.js`) — phase
+tabs, progress, failed count, variation count, model, source, and age.
+`GET /api/v1/sweeps` polled every 5s. Row click → sweep detail.
+
+### Sweep detail (`/sweeps/:ns/:name`)
+
+One AIPerfSweep workbench (`pages/sweep-detail.js`): header (phase, model,
+epoch selector, and the currently executing variation), conditions, a KPI row
+(variations / completed / failed plus headline peak metrics), an
+aggregate-artifacts card, a live trial board while running, a variation curve
+(metric selector + chart + table), a children table, and a diagnostics panel
+while live.
+
+Adaptive search has a deliberately state-aware surface:
+
+| State | Surface | Claim the UI may make |
+|---|---|---|
+| Live adaptive search | **Optimization study** with a **Current leader** | The best observation seen so far is provisional; the planner is still sampling and no final recommendation is shown. |
+| Successful terminal adaptive search with `search_summary.best_trials` | **Planner verdict** | The planner's final operating point, stopping evidence, and any SLA boundary. |
+| Failed, cancelled, unknown, or terminal adaptive search without a verdict | **No final recommendation** | The UI directs the reader to the trial history and search artifact; it never promotes a partial result to a winner. |
+| Grid/generator sweep | **Variation curve** | The curve and table are the result; no browser-derived winner summary is shown. |
+
+Pareto analysis appears only for a sweep that declared more than one objective.
+It is not used as a decorative throughput-versus-latency chart for a
+single-objective or grid sweep.
+
+The headline peak tiles (`Peak output tok/s`, `Peak req/s`, `Best TTFT p50`,
+`Best req lat p99`) report the extremum across **every** variation, feasible or
+not — "how much can this serve if I ignore latency" is a real question, and the
+variation table below the tiles is unfiltered too. So that a peak the
+constrained search *rejected* cannot be mistaken for the sweep's answer, each
+tile states which SLA regime its number is from:
+
+| Tile shows | When |
+|---|---|
+| `breaches SLA`, amber, no gold "award" tone | The variation that produced this extremum fails at least one `spec_summary.sla_filters` entry. Hover names the constraint, the observed value, and the best SLA-feasible alternative among the charted variations. |
+| `meets SLA`, green | The variation satisfies every declared filter. |
+| no feasibility line at all | Either the sweep declared no constraints (`search_summary.sla_filter_count == 0`, which makes every `feasible` flag in the API vacuously true), or it declared some that this page cannot check — `spec_summary.sla_filters` absent on an older archive, or a constraint on a metric the page does not collect. In the second case the tooltip says the tile is **not** filtered for feasibility, rather than leaving its silence to be read as a pass. |
+
+The final verdict comes from `search_summary.best_trials[0]`, the search
+planner's own result recorded from trial-level data. Its headline metric label,
+unit, and direction all come from the objective itself, never from the chart
+selector. An objective the planner could not score on the chosen trial renders
+as `not measured` rather than borrowing a neighbouring objective's number.
+
+**Endpoints consumed:** `GET /api/v1/sweeps/{ns}/{name}[?epoch=]` (5s),
+`.../cells`, `.../epochs`, `.../children`,
+`.../epochs/{epoch}/artifacts`, and per-child `GET /api/v1/jobs/{ns}/{name}`.
+
+### Leaderboard (`/leaderboard`)
+
+Cross-run ranking for a chosen metric + stat (`pages/leaderboard.js`): a
+top-10 horizontal bar chart plus a ranked table, with namespace / model /
+endpoint cross-filters. `GET /api/v1/analytics/leaderboard?metric=&stat=&limit=1000`
+(fetched per selection, not polled). Rows link to the run workbench.
+
+### Compare (`/compare`)
+
+Multi-run comparison (`pages/compare.js`). Left: a job selector with search,
+namespace/model/endpoint facet chips, and quick-pick buttons. Right: a
+metric-comparison table (direction-aware best-value highlight), a grouped bar
+chart, and throughput/latency Pareto scatters. Loads the run list from
+`GET /api/v1/results`, then `GET /api/v1/analytics/compare?jobs=...` on compare.
+Deep-linkable via a `?cluster=` query param. Requires ≥2 selections.
+
+### Compare epochs (`/compare/:ns/:name/:epochA/:epochB`)
+
+A fixed nine-metric diff of two epoch-pinned run summaries of a single run
+(`pages/compare-epochs.js`) — columns Metric / Run A / Run B / Δ. Each side is
+fetched through the quick-export alias
+`GET /api/v1/results/{ns}/{name}/runs/{epoch}/profile_export`, so a run whose
+`artifacts.prefix` renamed the summary file still diffs. When one side has no
+summary, that column reads `n/a` instead of failing the page.
+
+### History (`/history`)
+
+One metric's value over time across runs (`pages/history.js`): a line chart
+plus a data-points table, with namespace / model / endpoint filters synced to
+the URL. `GET /api/v1/analytics/history?metric=&stat=&namespace=&model=&endpoint=&limit=10000`
+— the filters are pushed to the server *and* re-applied client-side, and the
+table warns "may be truncated" once the response hits the 10000-row request cap.
+
+### Log strip (bottom bar)
+
+`LogStrip` (`components/log-strip.js`) is an always-on strip pinned to the
+bottom of every page. It derives lifecycle events **client-side** by diffing
+successive `/api/v1/jobs` snapshots (new run detected, phase transition,
+worker-ready change) — it consumes **no** endpoint of its own and keeps only an
+in-memory ring buffer of the last 120 events, so its history is lost on reload.
+Filter tabs: All / Warn / Error. Each entry links to the run workbench. It is
+**not** a durable cross-namespace audit log.
+
+---
+
+## Command Palette
+
+Press **`Ctrl+K`** (or `Cmd+K` on macOS) to toggle the command palette — the
+same shortcut closes it. The search button at the right end of the top bar opens
+the same modal.
+
+The palette (`components/command-palette.js:9-17`) indexes:
+
+- The six nav pages — Dashboard, Jobs, Sweeps, Leaderboard, Compare,
+  History — each with the sub-label "Page".
+- Every AIPerfJob from the current `jobs` signal — sub-label `ns: <namespace>`,
+  selecting navigates to that job's workbench (`/jobs/<ns>/<name>`, pinned to
+  its epoch when known).
+
+There are no namespace entries. Type to fuzzy-match either the label or the
+sub-label; matching is in-order-character, not substring. Navigation:
+
+| Key | Action |
+|---|---|
+| `↑` / `↓` | Move highlight |
+| `Home` / `End` | Jump to first / last |
+| `Enter` | Select the highlighted item |
+| `Tab` | Suppressed — focus is trapped on the search input so it cannot escape to the page behind the modal |
+| `Escape` or backdrop click | Close |
+| Mouse hover | Move highlight |
+
+---
+
+## Theme and Layout
+
+The dashboard is **dark-only**, and the theme is not configurable — not by an
+in-app control, not by the OS `prefers-color-scheme` setting, and not from the
+browser console. `index.html` sets `data-theme="dark"` in a synchronous inline
+script before the stylesheet loads (so a reload cannot flash unstyled content),
+and `initTheme()` in `lib/theme-switch.js` pins the same constant after hydration.
+The color tokens live in `src/aiperf/operator/ui/lib/theme.js` (the JS palette
+that every Chart.js consumer imports) and in `style.css`.
+
+Earlier builds did resolve an auto / light / dark preference from
+`localStorage['aiperfTheme']` and from `prefers-color-scheme`. That was removed
+because it could not work: `lib/theme.js` is a hardcoded dark palette that reads
+no CSS custom properties, so a light chrome would have rendered around dark
+charts. Worse, it was not inert — every visitor whose OS preferred light got
+`data-theme="light"` on `<html>` with no control involved, and `style.css`
+neutralized only part of the light palette, so 13 of its 73 custom properties
+leaked into the dark UI (including a low-contrast muted accent and an inverted
+table-row hover). `style.css` now contains no `[data-theme]` selector at all,
+which `tests/ui/test_operator_css_static_edges.py` enforces.
+
+Reviving light mode would mean making `lib/theme.js` read CSS custom properties
+and re-theming every chart, not re-adding a toggle.
+
+Model colors in charts are assigned deterministically from a hash of the model
+name, so the same model keeps the same color across pages and reloads.
+
+The layout is a single column: the sticky top bar, then a workspace chrome strip
+holding the breadcrumb, an `EXPERIMENTAL / Operator UI preview` banner, the
+data-freshness strip, and an optional global error banner; then the current
+page; then a persistent log strip at the bottom. The SPA is responsive down to
+tablet widths; very narrow viewports are not a supported target.
+
+---
+
+## Troubleshooting
+
+### Blank page with console 404s for `/app.js`
+
+The UI assets were not baked into the operator image, or `ui_dir.is_dir()`
+returned false at startup, in which case `create_app()` silently skips the
+`StaticFiles` mount — there is no log line for it either way. Verify the image
+tag includes `src/aiperf/operator/ui/`; `curl -sI http://localhost:8081/app.js`
+returning `404` while `/healthz` returns `200` confirms the mount is missing.
+
+### "Error: API 503 …" banners
+
+The Results API returned 503 — typically because `ResultsDB` hasn't finished
+initializing, or the kubernetes_asyncio client failed to load config. Check
+the operator pod logs:
+
+```bash
+kubectl logs -n aiperf-system deploy/aiperf-operator -c results-server --tail=200
+```
+
+If the line `kubernetes_asyncio client initialized for UI endpoints` is
+missing, the live job and cluster endpoints will stay unavailable even after
+the analytics engine comes up (the startup path logs
+"Kubernetes client unavailable, live job endpoints disabled" instead). The
+Dashboard page surfaces this as a "Cluster endpoint unavailable — GPU/node
+counts may be stale" banner.
+
+### Dashboard KPI tiles show `---` for throughput
+
+The Dashboard's KPI tiles (Peak Throughput, Best TTFT, Token Throughput) and
+the throughput-vs-latency scatter only populate from **completed** jobs whose
+summary carries the relevant fields (e.g. `request_throughput.avg`). If your
+runs never finished, the tiles fall back to `---`. Open the run workbench from
+the recent-jobs table to inspect individual runs instead.
+
+### Port-forward drops during operator rollout
+
+`aiperf kube dashboard` **auto-reconnects with backoff** and pins the local
+port across reconnects, so an open browser tab keeps working after a rollout
+that terminates the operator pod — no need to re-run the command. Press
+`Ctrl+C` to stop the forward.
+
+### Cancel fails from the dashboard
+
+Cancel is never unauthenticated: the browser must supply the
+operator's bearer token. A `401` means the token you entered is wrong (the SPA
+discards it and re-prompts); a `403` means the server has mutating routes turned
+off entirely, or has them on with no token configured, and no browser input can
+get past that. Verify the operator has
+`AIPERF_OPERATOR_MUTATING_ROUTES_ENABLED=true` and a non-empty
+`AIPERF_OPERATOR_MUTATING_ROUTES_TOKEN`. Read-only dashboard/API calls continue
+to work without this token.
+
+When mutating routes are off, use an authenticated terminal instead:
+
+```bash
+# Cancel a running AIPerfJob.
+kubectl patch aiperfjob <name> -n <namespace> --type=merge -p '{"spec":{"cancel":true}}'
+```
+
+Two related notes: cancelling an *archived* run (PVC results present, CR
+deleted) returns `400` — there is nothing left to patch. And
+`POST /admin/index/rebuild` is mounted disabled and returns `503` regardless of
+credentials; restart the operator pod to rebuild the index.
+
+---
+
+## Isolated Plotly Dashboard Sidecar (opt-in)
+
+The Plotly Dash plot-building runs in its own container in the operator
+Pod, behind the `dashboard.enabled` Helm value (default `false`). When
+enabled:
+
+- The operator Pod runs three containers: `operator`,
+  `results-server`, and `dashboard`.
+- `results-server` reverse-proxies `/dashboard/*` to
+  `localhost:<dashboard.port>` so external callers still hit one URL
+  (the existing `results-server.port`, default 8081).
+- The SPA's "Plots ↗" top-nav link appears, opening `/dashboard/` in
+  a new tab. The link is gated by `/api/v1/config/features`'s
+  `dashboard_enabled` field so a misconfigured chart fails closed.
+- After every benchmark completion, the operator fires a
+  fire-and-forget `POST /admin/refresh` against the dashboard sidecar
+  so the next `/dashboard/` view sees the new run.
+
+### Memory budgeting
+
+By default the dashboard container has `requests: 1Gi` and **no
+memory limit** — it can burst to whatever the node has free. This
+matches the original in-process behaviour but isolates blast radius
+to a single container. To enforce a ceiling on shared clusters:
+
+```yaml
+dashboard:
+  enabled: true
+  resources:
+    limits:
+      memory: 4Gi
+```
+
+When the limit is exceeded, only the dashboard container is
+OOMKilled — `results-server` (API, jobs router, WS) and the operator
+keep running.
+
+### Disabling
+
+```bash
+helm upgrade ... --set dashboard.enabled=false
+```
+
+When off, the `/dashboard/*` route returns 503 with a friendly body
+and the SPA hides the "Plots ↗" link.
+
+### Smoke test
+
+1. `helm upgrade ... --set dashboard.enabled=true` — three containers
+   in the operator Pod; "Plots ↗" link visible in the SPA top-nav.
+2. Run a benchmark to completion. The operator POSTs `/admin/refresh`
+   to the dashboard sidecar after a successful completion claim and the
+   dashboard log shows the rebuild. (A `dashboard refresh skipped`
+   DEBUG line in the operator log means the POST *failed* and was
+   swallowed — refresh is best-effort.) Click "Plots ↗" — the new run
+   is in the Dash app's run picker.
+3. `--set dashboard.enabled=false` — link gone; `/dashboard/` returns
+   503; dashboard container absent from the Pod.
+4. `--set dashboard.resources.limits.memory=512Mi` — cap enforced;
+   OOMKill of dashboard alone does not restart results-server or operator.

+# Debug Command
+
+`aiperf kube debug` produces a one-shot diagnostic snapshot of a benchmark namespace: which pods are in trouble, what Kubernetes events fired recently, what the cluster nodes look like, and — in verbose mode — the tail of every problem pod's logs. It is designed for triage *after* a benchmark has misbehaved, not for live observation.
+
+If you need continuous updates while a benchmark is running, use [`aiperf kube attach`](./attach.md) instead.
+
+---
+
+## When to Use Which Command
+
+AIPerf ships three cluster-inspection commands that overlap in theme but serve different moments in the lifecycle:
+
+| Command | Timing | Duration | What it answers |
+|---|---|---|---|
+| `aiperf kube preflight` | Before deploy | One-shot | "Will my cluster even accept this job?" (JobSet CRD and controller present, RBAC permissions granted, nodes have capacity) |
+| `aiperf kube attach` | During a run | Streaming | "What is the job doing right now?" (live progress from the controller) |
+| `aiperf kube debug` | After something went wrong | One-shot | "Why did this job fail or stall?" (container-status problem map, recent events, node pressure, failed-pod logs) |
+
+Use `debug` when:
+
+- A benchmark is stuck in Pending and you want a single report to attach to an issue.
+- Pods are CrashLoopBackOff-ing and you want all their log tails in one place.
+- The operator's `status.phase` is `Failed` and you want a post-mortem summary without scripting `kubectl` calls.
+- An AI agent is triaging a failure and needs a structured, grep-friendly snapshot.
+
+Use `aiperf kube list --watch` instead when the job is still running and you
+want to catch the state transition as it happens. Use `aiperf kube attach` for
+the live progress and log stream of one job.

+## CLI Reference
+
+```
+aiperf kube debug [OPTIONS]
+```
+
+All flags are optional. With no flags, `debug` falls back to the namespace of the last benchmark deployed from this machine (the same record `aiperf kube results` uses) and inspects every AIPerf pod it finds there.
+
+| Flag | Short | Default | Description |
+|---|---|---|---|
+| `--namespace` | `-n` | last-deployed benchmark's namespace | Kubernetes namespace to inspect. |
+| `--job-id` | `-j` | (auto-resolve) | AIPerf job ID **or AIPerfSweep name** to diagnose. A sweep name selects `status.currentChildRef.name`, or its latest completed `status.runs[].childName` when no child is running, and restricts the report to that child's pods. |
+| `--all-namespaces` | `-A` | `false` | Inspect every namespace that contains at least one AIPerf JobSet. |
+| `--verbose` | `-v` | `false` | Fetch logs from problem pods and show all recent events (not just `Warning`s). |
+| `--variation` | | (unset) | When `--job-id` is an AIPerfSweep name, target child variation index (0..199); resolves to `<sweep>-v<idx:02d>[-t<trial>]`. `-v` is reserved for `--verbose`, so use the long form. |
+| `--trial` | `-t` | (unset) | Trial index (0..9) within a sweep variation. Requires `--variation`. |
+| `--kubeconfig` | | `$KUBECONFIG` or `~/.kube/config` | Path to kubeconfig file. |
+| `--kube-context` | | current context | Kubernetes context to use. |
+
+### Namespace resolution order
+
+`debug` picks its target(s) using the first rule that matches:
+
+1. `-A` / `--all-namespaces` — list every namespace with an AIPerf JobSet.
+2. `-j <job-id>` — resolve the AIPerfJob / AIPerfSweep / JobSet with that name and use its namespace. For an AIPerfSweep, select the current child or latest completed child; use `--variation` and optionally `--trial` to choose a different child explicitly. Prints a warning and returns without a report when the sweep has not exposed any child yet.
+3. `-n <namespace>` — use the given namespace verbatim.
+4. Fall back to the namespace recorded for the last benchmark deployed from this machine (`default` when that record carries no namespace). When no last-benchmark record exists at all, `debug` prints `No job_id specified and no previous benchmark found` and returns without a report.
+
+---
+
+## What It Collects
+
+For each target namespace, `debug` gathers five independent slices of cluster state and renders them as sections in the report. The collection is best-effort: a failing API call in one section does not prevent the others from being displayed.
+
+### 1. Pod problem map
+
+Every AIPerf pod in the namespace (selected by the `app=aiperf` label — `AIPerfLabels.SELECTOR` in `src/aiperf/kubernetes/constants.py` — or a narrower per-job selector when `-j` is set, which appends `aiperf.nvidia.com/job-id=<job-id>`) is walked for container-status problems. See `_extract_pod_info` in `src/aiperf/cli_commands/kube/_debug_extract.py` — every init and app container status is classified into one of:
+
+| State | Severity | Suggested action |
+|---|---|---|
+| `CrashLoopBackOff` | CRITICAL | Check logs for the root cause. |
+| `ImagePullBackOff` | CRITICAL | Verify the image name and registry access. |
+| `ErrImagePull` | CRITICAL | Check image name, tag, and pull secrets. |
+| `OOMKilled` (current or previous) | CRITICAL | Increase memory limits. |
+| `CreateContainerConfigError` | ERROR | Check ConfigMaps, Secrets, and volume mounts. |
+| `RunContainerError` | ERROR | Check security context and resource limits. |
+| Pending with a waiting `reason` (e.g. `ContainerCreating`, `PodInitializing`) | WARNING | Container is waiting for the given reason. |
+| `Unschedulable` (pod-level condition) | CRITICAL | Check node resources, taints/tolerations, and node selectors. |
+
+The report also shows each pod's `phase`, total restart count across init and app containers, and the node it landed on.
+
+### 2. Benchmark diagnostics
+
+When `-j` / `--job-id` targets a specific AIPerfJob, directly or by resolving
+an AIPerfSweep child, the operator-published
+`status.liveMetrics` is run through the detectors in
+`src/aiperf/kubernetes/benchmark_diagnosis.py` (`diagnose_benchmark`).
+These complement the pod problem map above: that section reports *container*
+faults, this one reports what the *benchmark* is doing. When the CR's `.status`
+cannot be re-fetched, a minimal status is reconstructed from the cached job
+projection so the detectors still run.
+
+| Finding | Trips when | Threshold env var |
+|---|---|---|
+| `high_error_rate` | the `request_error_rate` metric, converted from percentage points to a fraction, exceeds the threshold | `AIPERF_K8S_DIAGNOSIS_HIGH_ERROR_RATE_THRESHOLD` (default `0.05`) |
+| `high_latency` | request-latency p99 exceeds N x the average | `AIPERF_K8S_DIAGNOSIS_HIGH_LATENCY_P99_MULTIPLIER` (default `10.0`) |
+| `stalled_pending` | phase is `Pending` for longer than the threshold | `AIPERF_K8S_DIAGNOSIS_STALLED_PENDING_THRESHOLD_SECONDS` (default `60.0`) |
+| `stalled_running` | phase is `Running` past the threshold with **zero** throughput **and** zero completed requests | `AIPERF_K8S_DIAGNOSIS_STALLED_RUNNING_THRESHOLD_SECONDS` (default `30.0`) |
+
+`stalled_running` deliberately requires both signals to be absent: throughput
+legitimately reads `0.0` between liveMetrics windows on a healthy run, so
+throughput alone would produce false alarms.
+
+`high_error_rate` reads `request_error_rate` rather than the raw counters
+because it is the only error signal that reaches `status.liveMetrics` at all:
+`error_request_count` carries `MetricFlags.ERROR_ONLY` and is filtered out
+before publication. Note the unit mismatch this creates — `request_error_rate`
+is in **percentage points** (`100 x errors / completed`) while
+`AIPERF_K8S_DIAGNOSIS_HIGH_ERROR_RATE_THRESHOLD` is a **fraction**, so the
+detector divides by 100 before comparing. The denominator is completed requests
+(successes + errors), taken from `completed_request_count`; `request_count`
+counts valid requests only and is never the denominator. The finding's detail
+line omits the `(errors/total)` counts on an all-error run, where no counter is
+published and only the rate survives.
+
+The section is omitted entirely when nothing trips, and when no specific job is
+targeted (`-A` or a bare namespace), since the detectors need one CR's status.
+
+#### Worker-state source
+
+`AIPerfJob.status.workers.total` is set at job creation from
+`RuntimeConfig.workers`, and `ready` comes from the JobSet's
+`replicatedJobsStatus[name="workers"].ready` pod count multiplied by
+`workersPerPod` (`_update_worker_counts` in
+`src/aiperf/operator/handlers/monitor.py`) —
+not from the controller pod. The controller's own worker view is served by its
+API sidecar, which queries the SystemController's authoritative worker tracker
+for each response, so a sidecar
+that starts late or misses a pub/sub update still reports current data. The
+internal `/api/debug/pod-states` and `/api/debug/worker-startup-states`
+endpoints use the same snapshot and identify it with `source: controller`.
+During controller startup, shutdown, or an RPC timeout, both API paths fall
+back to their local bus-fed cache; the debug response then reports
+`source: cache`. The query timeout is controlled by
+`AIPERF_API_SERVER_GET_POD_STATES_TIMEOUT` (default `2.0` seconds).
+
+### 3. Namespace events
+
+Recent `Event` objects are fetched from the target namespace (CoreV1 `list_namespaced_event`) and sorted newest-first. By default `debug` shows up to 15 `Warning` events; with `-v` it widens to the 30 most-recent events of any type. See `_get_namespace_events` in `src/aiperf/cli_commands/kube/debug.py`.
+
+### 4. Node resources
+
+Cluster-wide node information is collected once per invocation (shared across all namespaces when `-A` is set). For each node the report shows:
+
+- Ready condition
+- CPU capacity and allocatable
+- Memory capacity and allocatable
+- `nvidia.com/gpu` capacity and allocatable (rendered as `-` when the node reports no GPUs)
+- Any active pressure conditions: `MemoryPressure`, `DiskPressure`, `PIDPressure`
+
+See `_get_node_resources` in `src/aiperf/cli_commands/kube/debug.py`.
+
+### 5. Problem pod logs (verbose only)
+
+When `-v` is passed, `debug` calls `read_namespaced_pod_log` on every container of every pod flagged with at least one problem, tailing the last 20 lines. If the API call fails (pod deleted, container not yet started, RBAC denied), the report substitutes `<logs unavailable>` or `<error fetching logs>` and continues. See `_get_problem_pod_logs` in `src/aiperf/cli_commands/kube/debug.py`.
+
+---
+
+## Output Format
+
+`debug` renders a human-oriented Rich report to the terminal. Each namespace produces the same section sequence:
+
+1. `Diagnostic Report: <namespace>` header
+2. Pod overview table (`POD`, `STATUS`, `RESTARTS`, `NODE`, `ISSUES`), or a `No pods found` warning
+3. `Problems Found` list (or a `Problems` header with `No problems detected` on a clean namespace)
+4. `Benchmark Diagnostics` list (only when a specific job was targeted and at least one detector tripped)
+5. `Warning Events` table (or `Recent Events` table under `-v`). Without `-v` and with no warning events, `No warning events found` is printed instead; under `-v` with no events at all the section is omitted
+6. `Node Resources` table (omitted when no nodes could be listed)
+7. `Problem Pod Logs` sections (only under `-v`, only for pods with problems)
+8. `Summary` footer (pod counts, warning-event count, nodes under pressure)
+
+The report is rendered by `_print_report` in `src/aiperf/cli_commands/kube/_debug_report.py`.
+
+`debug` does not currently emit machine-readable JSON. If you need structured output for automation, script against `kubectl get events`, `kubectl get pods -o json`, and `kubectl get aiperfjob -o json` directly.
+
+---
+
+## Triage Recipes
+
+The scenarios below are grouped by the symptom you'd see in `aiperf kube list`. Each one shows the exact command to run and what to look for in the output.
+
+### Pod OOMKilled mid-run
+
+Symptom: a worker pod restarts repeatedly; `list --watch` shows request-rate gaps.
+
+```bash
+aiperf kube debug -j aiperf-bench-7f2a -v
+```
+
+In the report:
+
+- **Problems Found** section — look for `OOMKilled` or `OOMKilled (previous)` rows. The pod name is in brackets.
+- **Summary** — `Nodes under pressure:` will list any node reporting `MemoryPressure`; if the OOM pod is pinned there, the node is the root cause rather than your memory request.
+- **Problem Pod Logs** — the last 20 lines usually show the allocation site (e.g. a large dataset load).
+
+Fix by raising the container's memory limit.
+
+### ImagePullBackOff on a fresh deployment
+
+Symptom: `aiperf kube list` shows the job in `Pending` for minutes; no worker pods have transitioned to `Running`.
+
+```bash
+aiperf kube debug -j aiperf-bench-7f2a
+```
+
+In the report:
+
+- **Problems Found** — `ImagePullBackOff` or `ErrImagePull` with container name.
+- **Warning Events** — the `Failed` event's `MESSAGE` column contains the actual registry error (unauthorized, manifest not found, network unreachable).
+
+Fix by correcting the image tag in the spec, adding an `imagePullSecrets` reference, or verifying that cluster nodes can reach the registry.
+
+### PVC binding failure
+
+Symptom: pods stuck in `Pending`, but there is no image error.
+
+```bash
+aiperf kube debug -n my-benchmark -v
+```
+
+In the report:
+
+- **Problems Found** — an `Unschedulable` entry on a pod, severity `CRITICAL`, with a message like `persistentvolumeclaim "aiperf-results" not found` or `0/4 nodes are available: pod has unbound immediate PersistentVolumeClaims`.
+- **Recent Events** (verbose) — the `FailedScheduling` events from the scheduler, repeated every few seconds.
+
+Fix by ensuring the StorageClass exists and a provisioner is running; see [configuration.md](./configuration.md#storage).
+
+### CrashLoopBackOff in the controller
+
+Symptom: `aiperf kube list` shows the job `Failed` within seconds of deploy.
+
+```bash
+aiperf kube debug -j aiperf-bench-7f2a -v
+```
+
+In the report:
+
+- **Problems Found** — the controller pod's container is in `CrashLoopBackOff`.
+- **Problem Pod Logs** — the tail almost always contains the Python traceback. Common causes: bad dataset URL, missing tokenizer HF token, invalid endpoint URL.
+
+Fix the config and redeploy. If the traceback mentions an AIPerf subsystem, cross-reference it against [ai-debugging-guide.md](./ai-debugging-guide.md).
+
+### Zero pods scheduled
+
+Symptom: `aiperf kube list` shows the job, but `kubectl get pods` in the namespace is empty.
+
+```bash
+aiperf kube debug -n my-benchmark -v
+```
+
+In the report:
+
+- **Pods table** — `No pods found` warning at the top.
+- **Recent Events** (verbose) — look for `JobSet` or `AIPerfJob` `Warning` events. Common causes: the operator failed to admit the CR (check the operator pod itself with `kubectl logs -n aiperf-system deploy/aiperf-operator`), or the JobSet hit a quota.
+- **Node Resources** — if every node reports `Ready: No` or pressure, the scheduler is refusing to place anything.
+
+Fix by correcting the CR, clearing quota, or resolving the node-level issue before redeploying.
+
+---
+
+## Exit Codes
+
+| Code | Meaning |
+|---|---|
+| `0` | Report printed successfully. Note: `debug` exits `0` even when problems are found — the report is the payload. |
+| `0` | `-j <job-id>` was given, no job exists with that ID. A user-facing `No AIPerf job found with ID` error is printed and `debug` returns cleanly. |
+| `0` | `-A` was given and no namespace contained an AIPerf JobSet. A warning is printed. |
+| `1` | Unrecoverable failure (kubeconfig missing, cluster unreachable, unexpected exception). The error is surfaced via the shared `cli_utils.exit_on_error(title="Error Running Diagnostics")` wrapper, which prints a traceback and a red panel, then exits `1`. |
+
+If you are wrapping `debug` from a script and need to distinguish "ran clean, found problems" from "ran clean, no problems", parse the **Summary** section — specifically the `Pods: N total, M running, K with issues` line.

+---
+
+# Direct Mode (no operator)
+
+Direct mode runs an AIPerf benchmark on Kubernetes without requiring the AIPerf
+operator (and the `AIPerfJob` CRD it owns) to be installed. The `aiperf kube`
+CLI instead creates the underlying Kubernetes resources — `Role`,
+`RoleBinding`, `ConfigMap`, and `JobSet` — directly against the API server via
+`kubernetes_asyncio`. The namespace is never created for you: it must already
+exist, and `--namespace` (or a namespace pinned on your kubeconfig context) is
+required.
+
+It is triggered explicitly with `--no-operator`:
+
+```bash
+aiperf kube profile --model Qwen/Qwen3-0.6B \
+    --url http://server:8000 --image aiperf:latest --no-operator
+```
+
+or automatically when `aiperf kube profile` detects that the `AIPerfJob` CRD
+is not installed on the cluster. The CLI prints which mode it chose:
+
+```
+AIPerfJob CRD detected, using operator mode
+# or
+AIPerfJob CRD not found, deploying directly (no operator)
+```
+
+## What direct mode is not
+
+Direct mode still uses:
+
+- The same container image (`--image`) and the same JobSet topology (one
+  controller pod plus N worker pods).
+- The same `ConfigMap` containing the run config.
+- The same per-namespace `Role` / `RoleBinding` (`RBACSpec`), which grants the
+  benchmark's ServiceAccount read/watch on pods, pod logs, jobs, ConfigMaps,
+  Services, Endpoints, and Events, plus `patch` on JobSets — all scoped to the
+  benchmark namespace, and with no create, update, or delete verb anywhere. The
+  `aiperfjobs` rule is included too and is simply inert without the CRD.
+- The same live attach workflow (`aiperf kube attach`), which streams
+  WebSocket progress through a port-forward to the controller pod.
+
+What it does not use is the cluster-scoped operator Deployment, the
+`AIPerfJob` custom resource, and anything that lives on the operator side —
+dashboard UI, cross-job analytics, and the operator PVC that aggregates
+results across runs.
+
+You can still use an `AIPerfJob` YAML as the input to direct mode. The CLI
+projects its JobSet-compatible deployment fields into the raw manifests, so
+pod templates, scheduling, resource mode, failed-pod retention, image policy,
+and an authored TTL are preserved. Explicit benchmark and Kubernetes CLI flags
+overlay that YAML with the same precedence used in operator mode.

+| Analytics: leaderboard / compare / history | Served by operator (cross-job view over PVC)       | Not available (no cross-job storage)                                                |
+| Results persistence                       | Controller publishes to operator PVC (durable)      | Results live only on the controller pod's ephemeral `emptyDir` volume              |
+| Automated TTL / cleanup                   | Operator reconciles terminal CRs and prunes them    | Relies on `JobSet.spec.ttlSecondsAfterFinished` (direct-mode default: 8 hours)      |
+| Preflight checks                          | Operator-side preflight before admitting the CR     | None automatically — run `aiperf kube preflight` yourself first                      |
+| Parameter sweeps and multi-run orchestration | `AIPerfSweep` + sweep-controller pod              | Not supported; `generate --no-operator` rejects these configs                        |
+| RBAC footprint                            | Cluster-scoped ServiceAccount for the operator      | Benchmark namespace only: one `Role` + `RoleBinding` per run                        |
+| Multi-user fairness (Kueue)               | Operator submits with Kueue labels end-to-end       | Supported — Kueue labels still flow through the `JobSet` spec                       |
+| `aiperf kube results` default path        | Pulls from the operator PVC (works post-pod-GC)     | Requires `--from-pods`; pulls from the controller pod while it's still alive        |
+| Concurrent benchmark isolation            | Operator reconciles; CR conflicts rejected          | CLI fails closed on any same-named resource, whatever its phase; you clean up |
+
+## When direct mode is appropriate
+
+Direct mode is the right choice when at least one of these holds:
+
+- You do not have cluster-admin rights and cannot install the AIPerf CRD or
+  the operator Deployment.
+- You are restricted to a single namespace (e.g. a tenant namespace in a
+  shared cluster) and your `RoleBinding` cannot grant cluster-wide access.
+- You are running a one-off ad-hoc benchmark and don't need cross-run
+  history, leaderboard, or compare views.
+- You're running a CI smoke test (`--detach`) against an ephemeral cluster
+  (kind, minikube, GitHub Actions kubernetes-in-docker) where installing the
+  operator per job is more overhead than the benchmark itself.
+
+Use operator mode when you need durable results across benchmark deletions,
+the dashboard or analytics UIs, or centralized multi-user job management.
+
+## End-to-end workflow
+
+The typical direct-mode run is three commands:
+
+```bash
+# 1. Deploy the benchmark. --no-operator forces direct mode; it is also
+#    picked automatically when the CRD is missing.
+aiperf kube profile \
+    --model Qwen/Qwen3-0.6B \
+    --url http://inference.example.com:8000 \
+    --image ghcr.io/nvidia/aiperf:v1.2.3 \
+    --total-workers 10 \
+    --concurrency 100 \
+    --namespace aiperf-bench \
+    --no-operator
+
+# 2. (Optional) If you detached, reattach any time before the JobSet TTL
+#    expires to stream progress.
+aiperf kube attach --namespace aiperf-bench
+
+# 3. Pull results off the controller pod BEFORE the JobSet TTL expires and
+#    the pod is garbage-collected. --from-pods is required in direct mode.
+#    --shutdown tells the controller API service to exit cleanly so the pod
+#    can terminate afterwards.
+aiperf kube results --from-pods --shutdown --namespace aiperf-bench
+```
+
+On a successful deploy the CLI prints one `Created <Kind>/<name>` line per
+resource. All names derive from the benchmark name as `aiperf-<name>` (the
+ConfigMap adds a `-config` suffix), where `<name>` is either your `--name` or
+the auto-generated `<model>-<endpoint-type>-<phase-type>` slug
+(`generate_benchmark_name`). For the run above:
+
+```
+Created Role/aiperf-<name>
+Created RoleBinding/aiperf-<name>
+Created ConfigMap/aiperf-<name>-config
+Created JobSet/aiperf-<name>
+```
+
+The target namespace must already exist -- direct mode never creates one,
+because doing so would require cluster-scoped namespace-create rights that
+most benchmark runners do not have. Every other resource is created fresh: a
+name collision fails the deploy rather than adopting the existing object.
+
+## Dry-run inspection
+
+Preview the manifests without submitting them:
+
+```bash
+aiperf kube profile --model Qwen/Qwen3-0.6B \
+    --url http://server:8000 --image aiperf:latest \
+    --no-operator --dry-run > bench.yaml
+
+kubectl apply -f bench.yaml   # equivalent to what the CLI would have done
+```
+
+The memory estimate is written to stderr, so `bench.yaml` contains only the
+multi-document Kubernetes YAML and can be passed directly to `kubectl apply`.
+
+`--no-operator` is required here and not merely a preference: `--dry-run`
+never contacts the cluster, so it cannot detect that the `AIPerfJob` CRD is
+absent and would otherwise print the operator CR as JSON instead of the
+manifests. The upside of that same design is that this command works with no
+cluster reachable at all — no kubeconfig, no network. See
+[workflow.md](./workflow.md#--dry-run-fidelity) for the full decision table
+and the pre-validation caveat.
+
+This is useful when your cluster requires a GitOps commit or a manual review
+before resources can be created.
+
+## Results retrieval
+
+In operator mode, `aiperf kube results` retrieves results from the operator's
+PVC — this works even after the benchmark pods have been garbage-collected.
+
+In direct mode there is no operator PVC. Results must be pulled via
+`--from-pods`, which port-forwards to the controller pod's API service
+(port 9090) and downloads the exported artifacts (`metrics.json`,
+`profile_export_aiperf.json`, console exports, parquet files, and checkpoint
+data). `--all` is the default; pass `--summary-only` to fetch just the
+summary results.
+
+There is one fallback, and only on the `--summary-only` path: if the API
+call fails, the CLI retries with `kubectl cp` against the `control-plane`
+container's `/results` directory. The default `--all` path has no such
+fallback — if the controller API is unreachable, retrieval fails outright.
+
+The controller pod also runs a small results sidecar on port 9091 that serves
+the same `/results` volume (see `src/aiperf/kubernetes/results_sidecar.py`)
+and outlives the main controller container, but `aiperf kube results
+--from-pods` never targets it — only the operator's completion fetch does, so
+that fallback is unavailable in direct mode.
+
+**The pod must still exist when you run `aiperf kube results --from-pods`.**
+The direct-mode JobSet sets `ttlSecondsAfterFinished` to 8 hours by default
+(`K8sEnvironment.JOBSET.DIRECT_MODE_TTL_SECONDS`, tunable via
+`AIPERF_K8S_JOBSET_DIRECT_MODE_TTL_SECONDS`), giving you a generous window
+before the pod is deleted. Pass `--ttl-seconds` on `profile` to override.
+
+## Cleanup
+
+Operator mode cleans up by deleting the `AIPerfJob` CR; the operator
+reconciles the deletion and removes all child resources.
+
+Direct mode has no CR, so cleanup is manual — `aiperf kube delete` and
+`aiperf kube cleanup` both operate on `AIPerfJob` / `AIPerfSweep` CRs and
+will not find a direct-mode run. Every resource is named
+`aiperf-<name>` (the ConfigMap adds `-config`), so once results are safely
+pulled:
+
+```bash
+kubectl delete jobset     aiperf-<name>        -n <namespace>
+kubectl delete configmap  aiperf-<name>-config -n <namespace>
+kubectl delete role       aiperf-<name>        -n <namespace>
+kubectl delete rolebinding aiperf-<name>       -n <namespace>
+```
+
+Or, if you created a dedicated namespace for the run and don't need it
+anymore:
+
+```bash
+kubectl delete namespace <namespace>
+```
+
+The default `ttlSecondsAfterFinished` on the `JobSet` means completed pods
+will eventually be reaped automatically, but the `ConfigMap`, `Role`, and
+`RoleBinding` will stay until you delete them (they are cheap, but
+accumulate).
+
+## Limitations
+
+- **No cross-job analytics.** Leaderboards, compare views, and the run
+  history UI are all served by the operator over its PVC; none of them work
+  in direct mode.
+- **Results are lost if the pod is deleted before you run `results`.**
+  Set a longer `--ttl-seconds` on `profile` if you plan to pull results
+  well after the run finishes, and prefer running `results --from-pods
+  --shutdown` at the end of the workflow.
+- **No operator-side admission / validation.** The operator normally
+  validates specs, checks quota, and can reject malformed CRs before any
+  pod starts. Direct mode skips all of it — including the endpoint check
+  (`--skip-endpoint-check` is accepted for CLI parity but is a no-op here).
+  Run `aiperf kube preflight` and `aiperf kube validate` yourself before
+  submitting.
+- **No CR lifecycle reconciler.** `timeoutSeconds`, `resultsTtlDays`, `cancel`,
+  and `failurePolicy` require the operator and therefore do not take effect in
+  direct mode. JobSet-native `ttlSecondsAfterFinished` and `keepFailedPods`
+  still apply.
+- **No CR-level status.** `kubectl get aiperfjob` does not work. Use
+  `kubectl get jobset` and `kubectl get pods -l app=aiperf` (plus
+  `aiperf kube logs` and `aiperf kube list`, which falls back to listing
+  JobSets when no `AIPerfJob` CRs are found) to observe the run.
+- **Existing resources with the same name.** Direct mode refuses to adopt an
+  existing Role, RoleBinding, ConfigMap,
+  or JobSet because there is no owner CR or immutable run UID that can prove
+  the resource belongs to the new invocation. Pass a unique `--name` or delete
+  all resources from the prior direct-mode run first.

+
+This guide walks you through benchmarking an NVIDIA Dynamo inference server on Kubernetes using AIPerf. By the end, you will have a cluster running, both operators installed, a benchmark executed against a Dynamo deployment, and your results downloaded.
+
+The same workflow applies to any OpenAI-compatible endpoint (vLLM, TRT-LLM, SGLang) -- just change the endpoint URL and model name.
+
+---
+
+
+## Cluster Setup
+
+If you already have a Kubernetes cluster with GPU nodes and `kubectl` configured, skip to [Prerequisites](#prerequisites).
+
+### Option A: Use an Existing Cluster
+
+Any Kubernetes v1.24+ cluster with NVIDIA GPUs works. You need:
+
+- `kubectl` configured to talk to the cluster
+- GPU nodes with the NVIDIA device plugin installed
+- Permissions to install CRDs and create namespaces
+
+Verify your connection:
+
+```bash
+kubectl cluster-info
+kubectl get nodes -o custom-columns=NAME:.metadata.name,GPU:.status.allocatable.nvidia\\.com/gpu
+```
+
+If GPUs show up, skip to [Prerequisites](#prerequisites).
+
+### Option B: Create a Local Kind Cluster with GPU Passthrough
+
+[Kind](https://kind.sigs.k8s.io/) runs Kubernetes inside Docker containers on your local machine. With the NVIDIA container runtime configured as Docker's default, a Kind node can see the host's GPUs.
+
+**Host requirements:**
+- Docker with the NVIDIA container runtime as the default runtime
+- NVIDIA drivers installed on the host
+- `kind` CLI installed (`go install sigs.k8s.io/kind@latest` or [releases](https://kind.sigs.k8s.io/docs/user/quick-start/#installation))
+
+#### One-time Docker setup
+
+If you haven't already configured Docker for GPU passthrough:
+
+```bash
+# Enable volume-mount-based GPU injection
+sudo nvidia-ctk config --in-place \
+  --set accept-nvidia-visible-devices-as-volume-mounts=true
+
+# Set nvidia as the default Docker runtime
+sudo nvidia-ctk runtime configure --runtime=docker --set-as-default
+
+# Restart Docker to pick up changes
+sudo systemctl restart docker
+```
+
+Verify:
+
+```bash
+docker info 2>/dev/null | grep "Default Runtime"
+# Should show: Default Runtime: nvidia
+```
+
+#### Cluster setup
+
+Create the cluster:
+
+```bash
+kind create cluster --name aiperf
+```
+
+Install the NVIDIA device plugin so GPUs become an allocatable resource, and JobSet, which the AIPerf operator uses to run benchmark pods:
+
+```bash
+kubectl --context kind-aiperf apply -f \
+  https://raw.githubusercontent.com/NVIDIA/k8s-device-plugin/master/deployments/static/nvidia-device-plugin.yml
+
+kubectl --context kind-aiperf apply --server-side -f \
+  https://github.com/kubernetes-sigs/jobset/releases/latest/download/manifests.yaml
+```
+
+Build the AIPerf image locally and load it into the Kind node so pods can pull it without a registry:
+
+```bash
+docker build -t aiperf:local .
+kind load docker-image aiperf:local --name aiperf
+```
+
+Verify GPUs are allocatable:
+
+```bash
+kubectl --context kind-aiperf get nodes \
+  -o jsonpath='{.items[0].status.allocatable.nvidia\.com/gpu}'
+# Should show: 1 (or more)
+```
+
+#### Teardown
+
+To delete the cluster when you are done:
+
+```bash
+kind delete cluster --name aiperf
+```
+
+---
+
+## Prerequisites
+
+At this point you should have:
+
+- A Kubernetes cluster with `kubectl` configured
+- GPU nodes with the NVIDIA device plugin
+- [JobSet](https://github.com/kubernetes-sigs/jobset) installed
+- [Helm](https://helm.sh/) v3 installed locally
+- AIPerf installed locally (`uv tool install aiperf`, or `uv sync` from a source checkout)
+- Access to NGC container registry (`nvcr.io/nvidia/ai-dynamo`)
+
+Run the preflight checker to verify:
+
+```bash
+aiperf kube preflight
+```
+
+---
+
+## Step 1: Install the Operators
+
+You need two operators: the **Dynamo operator** (manages inference servers) and the **AIPerf operator** (manages benchmarks).
+
+### Install the Dynamo Operator
+
+```bash
+# Install Dynamo platform (CRDs are bundled into the platform chart in v1.x)
+helm install dynamo-platform \
+  oci://nvcr.io/nvidia/ai-dynamo/dynamo-platform \
+  --version 1.1.0 \
+  --namespace dynamo-system \
+  --create-namespace \
+  --set dynamo-operator.webhook.enabled=false \
+  --set grove.enabled=false \
+  --set kai-scheduler.enabled=false
+```
+
+Verify the Dynamo operator is running:
+
+```bash
+kubectl get pods -n dynamo-system
+```
+
+### Install the AIPerf Operator
+
+```bash
+helm install aiperf-operator deploy/helm/aiperf-operator \
+  --namespace aiperf-system \
+  --create-namespace
+```
+
+For Kind clusters using a locally built image, override the image:
+
+```bash
+helm install aiperf-operator deploy/helm/aiperf-operator \
+  --namespace aiperf-system \
+  --create-namespace \
+  --set image.repository=aiperf \
+  --set image.tag=local \
+  --set image.pullPolicy=Never
+```
+
+Verify it is running:
+
+```bash
+kubectl get pods -n aiperf-system
+```
+
+You should see `2/2` containers ready by default (operator + results-server). With the optional Plotly dashboard enabled (`dashboard.enabled=true`), the count becomes `3/3` (operator + results-server + dashboard).
+
+---
+
+## Step 2: Deploy a Dynamo Inference Server
+
+Create a `DynamoGraphDeployment`. This example deploys Qwen3-0.6B in aggregated mode using the vLLM backend:
+
+```yaml
+# dynamo-server.yaml
+apiVersion: nvidia.com/v1alpha1
+kind: DynamoGraphDeployment
+metadata:
+  name: dynamo-agg
+  namespace: dynamo-server
+spec:
+  services:
+    Frontend:
+      dynamoNamespace: dynamo-agg
+      componentType: frontend
+      replicas: 1
+      extraPodSpec:
+        mainContainer:
+          image: nvcr.io/nvidia/ai-dynamo/vllm-runtime:1.1.0
+          env:
+            - name: POD_UID
+              valueFrom:
+                fieldRef:
+                  fieldPath: metadata.uid
+    VllmWorker:
+      dynamoNamespace: dynamo-agg
+      componentType: worker
+      replicas: 1
+      resources:
+        limits:
+          gpu: "1"
+      extraPodSpec:
+        runtimeClassName: nvidia
+        mainContainer:
+          image: nvcr.io/nvidia/ai-dynamo/vllm-runtime:1.1.0
+          workingDir: /workspace/examples/backends/vllm
+          command: ["python3", "-m", "dynamo.vllm"]
+          args:
+            - "--model"
+            - "Qwen/Qwen3-0.6B"
+          env:
+            - name: POD_UID
+              valueFrom:
+                fieldRef:
+                  fieldPath: metadata.uid
+            - name: DYN_SYSTEM_PORT
+              value: "9090"
+```
+
+Apply it:
+
+```bash
+kubectl create namespace dynamo-server
+kubectl apply -f dynamo-server.yaml
+```
+
+Wait for the server to be ready (model loading can take a few minutes):
+
+```bash
+# Watch pods until all are Running
+kubectl get pods -n dynamo-server -w
+```
+
+Verify the endpoint is healthy:
+
+```bash
+kubectl run curl-test --rm -it --restart=Never --image=curlimages/curl -- \
+  curl -s http://dynamo-agg-frontend.dynamo-server.svc:8000/v1/models
+```
+
+---
+
+## Step 3: Run Your First Benchmark
+
+Now benchmark the Dynamo server. The Dynamo endpoint URL follows the pattern `http://{deployment-name}-frontend.{namespace}.svc:8000/v1`:
+
+```bash
+aiperf kube profile \
+  --model Qwen/Qwen3-0.6B \
+  --url http://dynamo-agg-frontend.dynamo-server.svc:8000/v1 \
+  --image nvcr.io/nvidia/aiperf:latest \
+  --total-workers 10 \
+  --request-count 500 \
+  --concurrency 50 \
+  --streaming
+```
+
+On a Kind cluster with a locally built image, point `--image` at the loaded tag and disable pulling. Substitute the Service URL of whatever OpenAI-compatible endpoint you are testing against:
+
+```bash
+aiperf kube profile \
+  --model Qwen/Qwen3-0.6B \
+  --url http://my-endpoint.default.svc:8000 \
+  --image aiperf:local \
+  --image-pull-policy Never \
+  --total-workers 10 \
+  --request-count 200 \
+  --concurrency 5 \
+  --streaming
+```
+
+What happens:
+
+1. AIPerf builds an `AIPerfJob` custom resource from your flags
+2. Submits it to the cluster, where the AIPerf operator picks it up
+3. The operator creates RBAC, a ConfigMap, and a JobSet with a controller pod and worker pods
+4. Workers send requests to the Dynamo frontend
+5. AIPerf polls the `AIPerfJob` status and streams progress to your terminal
+
+You will see the job phase, worker readiness (`ready/total`), and each status condition as the operator reports it. In `--no-operator` mode AIPerf attaches to the controller pod and tails its output instead.
+
+Press **Ctrl+C** to detach. The benchmark continues running in the cluster. To cancel it, run `aiperf kube cancel` or patch the CR directly:
+
+```bash
+kubectl patch aiperfjob <name> -n my-benchmarks --type=merge -p '{"spec":{"cancel":true}}'
+```
+
+---
+
+## Step 4: Using a Config File
+
+For repeatable benchmarks, use an AIPerfJob YAML file. Generate a starter template:
+
+```bash
+aiperf kube init --output benchmark.yaml
+```
+
+Edit it for your Dynamo deployment:
+
+```yaml
+apiVersion: aiperf.nvidia.com/v1alpha1
+kind: AIPerfJob
+metadata:
+  name: dynamo-benchmark
+spec:
+  benchmark:
+    models:
+      - "Qwen/Qwen3-0.6B"
+    endpoint:
+      urls:
+        - "http://dynamo-agg-frontend.dynamo-server.svc:8000/v1"
+      streaming: true
+    datasets:
+      - name: main
+        type: synthetic
+        entries: 1000
+        prompts:
+          isl:
+            mean: 512
+            stddev: 0
+          osl:
+            mean: 128
+            stddev: 0
+    phases:
+      - name: warmup
+        kind: warmup
+        type: concurrency
+        concurrency: 10
+        requests: 20
+      - name: profiling
+        kind: profiling
+        type: concurrency
+        concurrency: 50
+        requests: 500
+```
+
+Validate the config before deploying:
+
+```bash
+aiperf kube validate benchmark.yaml
+```
+
+Run it:
+
+```bash
+aiperf kube profile --config benchmark.yaml --image nvcr.io/nvidia/aiperf:latest
+```
+
+Or apply it directly with kubectl (the operator picks it up automatically):
+
+```bash
+kubectl apply -f benchmark.yaml
+```
+
+---
+
+## Step 5: Disaggregated Inference
+
+Dynamo's disaggregated mode separates prefill and decode into different pods for better GPU utilization. To benchmark a disaggregated deployment:
+
+1. Deploy Dynamo in disaggregated mode (separate prefill and decode workers with KV cache transfer):
+
+```yaml
+# dynamo-disagg.yaml
+apiVersion: nvidia.com/v1alpha1
+kind: DynamoGraphDeployment
+metadata:
+  name: dynamo-disagg
+  namespace: dynamo-server
+spec:
+  services:
+    Frontend:
+      dynamoNamespace: dynamo-disagg
+      componentType: frontend
+      replicas: 1
+      extraPodSpec:
+        mainContainer:
+          image: nvcr.io/nvidia/ai-dynamo/vllm-runtime:1.1.0
+          env:
+            - name: POD_UID
+              valueFrom:
+                fieldRef:
+                  fieldPath: metadata.uid
+            - name: DYN_ROUTER_MODE
+              value: "kv"
+    VllmPrefillWorker:
+      dynamoNamespace: dynamo-disagg
+      componentType: worker
+      subComponentType: prefill
+      replicas: 1
+      resources:
+        limits:
+          gpu: "1"
+      extraPodSpec:
+        runtimeClassName: nvidia
+        mainContainer:
+          image: nvcr.io/nvidia/ai-dynamo/vllm-runtime:1.1.0
+          workingDir: /workspace/examples/backends/vllm
+          command: ["python3", "-m", "dynamo.vllm"]
+          args:
+            - "--model"
+            - "Qwen/Qwen3-0.6B"
+            - "--is-prefill-worker"
+            - "--connector"
+            - "kvbm"
+          env:
+            - name: POD_UID
+              valueFrom:
+                fieldRef:
+                  fieldPath: metadata.uid
+            - name: DYN_KVBM_CPU_CACHE_GB
+              value: "1"
+    VllmDecodeWorker:
+      dynamoNamespace: dynamo-disagg
+      componentType: worker
+      subComponentType: decode
+      replicas: 1
+      resources:
+        limits:
+          gpu: "1"
+      extraPodSpec:
+        runtimeClassName: nvidia
+        mainContainer:
+          image: nvcr.io/nvidia/ai-dynamo/vllm-runtime:1.1.0
+          workingDir: /workspace/examples/backends/vllm
+          command: ["python3", "-m", "dynamo.vllm"]
+          args:
+            - "--model"
+            - "Qwen/Qwen3-0.6B"
+            - "--is-decode-worker"
+          env:
+            - name: POD_UID
+              valueFrom:
+                fieldRef:
+                  fieldPath: metadata.uid
+            - name: DYN_SYSTEM_PORT
+              value: "9090"
+```
+
+2. Benchmark it -- the endpoint URL changes to match the deployment name:
+
+```bash
+aiperf kube profile \
+  --model Qwen/Qwen3-0.6B \
+  --url http://dynamo-disagg-frontend.dynamo-server.svc:8000/v1 \
+  --image nvcr.io/nvidia/aiperf:latest \
+  --total-workers 20 \
+  --request-count 1000 \
+  --concurrency 100 \
+  --streaming
+```
+
+---
+
+## Step 6: View Results
+
+After the benchmark completes, retrieve your results:
+
+```bash
+aiperf kube results
+```
+
+This downloads the full results package including:
+
+- `profile_export_aiperf.json` -- Summary metrics (throughput, latency percentiles, TTFT, ITL)
+- `inputs.json` -- Dataset that was used
+- `server_metrics_export.json` -- Dynamo server metrics (frontend throughput, KV cache stats, component latencies); empty when discovery found no scrapable endpoints
+
+To retrieve results from a specific job:
+
+```bash
+aiperf kube results dynamo-benchmark
+```
+
+Results are stored on the operator's persistent volume by default, so `aiperf kube results` works even after benchmark pods are deleted. To retrieve directly from the benchmark pods instead (downloads every artifact through the controller's results API, so the controller pod must still be running):
+
+```bash
+aiperf kube results dynamo-benchmark --from-pods
+```
+
+Adding `--summary-only` narrows the download to the summary files and falls back to `kubectl cp` when the controller API is unreachable.
+
+### Dynamo Server Metrics
+
+When benchmarking Dynamo, AIPerf discovers and collects Prometheus metrics from pods with the `nvidia.com/metrics-enabled=true` label (or a recognizable inference-server image). By default discovery only searches the **benchmark job's own namespace** — the namespace the chart-provisioned benchmark RBAC can list pods in. If Dynamo runs in a different namespace (e.g. `dynamo-server`), set `server_metrics.discovery.namespace: dynamo-server` in the benchmark config **and** grant pod-read access there by adding that namespace to the chart's `serverMetricsDiscoveryNamespaces` value — a plain string entry binds the benchmark namespaces' `default` ServiceAccount, so benchmark pods running under a custom `podTemplate.serviceAccountName` need the `{namespace, serviceAccounts}` entry form (or a manual RoleBinding); see the [server-metrics guide](../server-metrics/server-metrics.md#kubernetes-auto-discovery) for the full RBAC prerequisite table and how to tune or disable discovery. Discovered metrics include:
+
+- **Frontend metrics** -- `dynamo_frontend_requests`, `dynamo_frontend_time_to_first_token_seconds`, `dynamo_frontend_inter_token_latency_seconds`, `dynamo_frontend_output_tokens`
+- **Component metrics** -- Per-worker `dynamo_component_requests`, `dynamo_component_kvstats_gpu_cache_usage_percent`, `dynamo_component_kvstats_gpu_prefix_cache_hit_rate`
+
+These are exported alongside the standard AIPerf metrics in the results package.
+
+---
+
+## Step 7: List and Manage Jobs
+
+See all benchmark jobs across namespaces:
+
+```bash
+aiperf kube list
+```
+
+```
+NAME                 NAMESPACE           OWNER  PHASE      WORKERS  PROGRESS  THROUGHPUT  LATENCY   AGE
+dynamo-benchmark     my-benchmarks       -      Completed  10/10    100%      142.3 rps   187.0 ms  5m
+disagg-test          my-benchmarks       -      Running    10/10    42%       98.1 rps    201.4 ms  2m
+```
+
+`WORKERS` is `ready/total` and `LATENCY` is the p99 request latency. `OWNER` is
+the scoped operator holding that namespace's claim, `-` when the cluster-wide
+operator reconciles it, or `?` when the claim could not be read. Use `--wide` to add model, endpoint, and error columns.
+
+Filter by status:
+
+```bash
+aiperf kube list --running
+aiperf kube list --completed
+aiperf kube list --failed
+```
+
+Watch jobs with live refresh:
+
+```bash
+aiperf kube list --watch
+```
+
+---
+
+## Web Dashboard
+
+The AIPerf operator includes a built-in web dashboard for monitoring benchmarks and analyzing results.
+
+Access it by port-forwarding to the operator:
+
+```bash
+kubectl port-forward -n aiperf-system deploy/aiperf-operator 8081:8081
+```
+
+Then open [http://localhost:8081](http://localhost:8081) in your browser.
+
+The dashboard provides:
+
+- **Dashboard** -- Overview with KPI cards, active jobs, and throughput trends
+- **Jobs** -- Sortable table of all benchmark jobs with phase filters
+- **Job Detail** -- Live metrics, charts, phase progress, and pod status for a single job
+- **Leaderboard** -- Rank benchmark runs by any metric

+## Dynamo Deployment Modes
+
+| Mode | Description | Endpoint URL Pattern |
+|------|-------------|---------------------|
+| `agg` | Aggregated -- single workers handle prefill + decode | `http://dynamo-agg-frontend.dynamo-server.svc:8000/v1` |
+| `agg-router` | Aggregated with KV-aware routing | `http://dynamo-agg-router-frontend.dynamo-server.svc:8000/v1` |
+| `disagg` | Disaggregated -- separate prefill and decode workers | `http://dynamo-disagg-frontend.dynamo-server.svc:8000/v1` |
+
+### Backends
+
+Dynamo supports three inference backends. Change the worker image and command:
+
+| Backend | Image | Worker Command |
+|---------|-------|---------------|
+| vLLM | `nvcr.io/nvidia/ai-dynamo/vllm-runtime:1.1.0` | `python3 -m dynamo.vllm` |
+| TRT-LLM | `nvcr.io/nvidia/ai-dynamo/trtllm-runtime:1.1.0` | `python3 -m dynamo.trtllm` |
+| SGLang | `nvcr.io/nvidia/ai-dynamo/sglang-runtime:1.1.0` | `python3 -m dynamo.sglang` |
+
+---
+
+## Without the Operator
+
+If you cannot install the AIPerf operator (e.g., limited cluster permissions), AIPerf can deploy benchmarks directly using raw Kubernetes manifests. Use `--no-operator`:
+
+```bash
+aiperf kube profile \
+  --model Qwen/Qwen3-0.6B \
+  --url http://dynamo-agg-frontend.dynamo-server.svc:8000/v1 \
+  --image nvcr.io/nvidia/aiperf:latest \
+  --no-operator
+```
+
+This creates RBAC, ConfigMap, and JobSet directly in an existing namespace. You lose operator features (automated monitoring, results storage, conditions) but the benchmark itself works the same way.
+
+To generate the manifests without applying them (useful for GitOps):
+
+```bash
+aiperf kube generate --no-operator \
+  --model Qwen/Qwen3-0.6B \
+  --url http://dynamo-agg-frontend.dynamo-server.svc:8000/v1 \
+  --image nvcr.io/nvidia/aiperf:latest \
+  > manifests.yaml
+```
+
+---
+
+## Quick Reference
+
+| Task | Command |
+|------|---------|
+| Check cluster readiness | `aiperf kube preflight` |
+| Generate config template | `aiperf kube init` |
+| Validate a config file | `aiperf kube validate benchmark.yaml` |
+| Run a benchmark | `aiperf kube profile --config benchmark.yaml --image <img>` |
+| Run without waiting | `aiperf kube profile ... --detach` |
+| Preview the operator CR without deploying | `aiperf kube profile ... --dry-run` |
+| Preview direct-mode manifests without deploying | `aiperf kube profile ... --no-operator --dry-run` |
+| Attach to a running job | `aiperf kube attach` |
+| Diagnose a stuck or failed job | `aiperf kube debug` |

+
+# GPU Telemetry on Kubernetes
+
+This page documents how AIPerf collects GPU telemetry when running on Kubernetes: the dedicated
+`gpu-telemetry-manager` sidecar container, how DCGM endpoints are resolved, and the
+ingest path into the final benchmark report.
+
+For the general (non-Kubernetes) tutorial — Dynamo setup, DCGM Exporter container
+flags, pynvml mode, custom metrics CSVs, and console/dashboard output — see
+[`docs/tutorials/gpu-telemetry.md`](../tutorials/gpu-telemetry.md). This page
+focuses only on what is Kubernetes-specific.
+
+## Opt-out by default
+
+GPU telemetry is **on by default** for every `aiperf kube profile` run. The
+`GpuTelemetryConfig` in [`src/aiperf/config/gpu_telemetry.py`](https://github.com/ai-dynamo/aiperf/blob/main/src/aiperf/config/gpu_telemetry.py)
+defaults `enabled=True`, and the JobSet spec propagates that through
+`AIPerfJobSetSpec.gpu_telemetry_enabled` in
+[`src/aiperf/kubernetes/jobset.py`](https://github.com/ai-dynamo/aiperf/blob/main/src/aiperf/kubernetes/jobset.py).
+
+To skip the sidecar entirely — useful for non-GPU inference targets, CPU-only
+clusters, or clusters without a DCGM Exporter reachable at the pod level —
+pass `--no-gpu-telemetry`:
+
+```bash
+aiperf kube profile --model Qwen/Qwen3-0.6B ... --no-gpu-telemetry
+```
+
+When disabled, the controller pod omits the `gpu-telemetry-manager` container
+and the memory estimator drops its allocation (see `_estimate_gpu_telemetry`
+in [`src/aiperf/kubernetes/_memory_estimator/components.py`](https://github.com/ai-dynamo/aiperf/blob/main/src/aiperf/kubernetes/_memory_estimator/components.py)).
+
+## No auto-discovery — user supplies the DCGM URLs
+
+AIPerf does **not** discover the in-cluster DCGM Exporter service via the
+Kubernetes API. The candidate endpoint list is built entirely from two
+sources:
+
+1. **`Environment.GPU.DEFAULT_DCGM_ENDPOINTS`** — built-in defaults
+   (overridable with `AIPERF_GPU_DEFAULT_DCGM_ENDPOINTS`):
+   - `http://localhost:9400/metrics`
+   - `http://localhost:9401/metrics`
+
+   Inside the controller pod, `localhost` addresses point at the pod itself,
+   which never runs DCGM — so the defaults are effectively unreachable on
+   Kubernetes and exist only for parity with local Docker runs.
+
+2. **`--gpu-telemetry <urls...>`** — user-supplied URLs, appended to the
+   defaults in order (deduplicated) by `GPUTelemetryManager` in
+   [`src/aiperf/gpu_telemetry/manager.py`](https://github.com/ai-dynamo/aiperf/blob/main/src/aiperf/gpu_telemetry/manager.py).
+
+For a Kubernetes run you almost always need to pass at least one explicit URL
+pointing at a cluster-reachable DCGM Exporter Service:
+
+```bash
+aiperf kube profile \
+    --model Qwen/Qwen3-0.6B \
+    --url dynamo-frontend.inference.svc.cluster.local:8000 \
+    --gpu-telemetry \
+        http://dcgm-exporter.gpu-operator.svc.cluster.local:9400/metrics
+```
+
+The URL scheme prefix (`http://`) is optional: bare `host:port` forms get an
+`http://` prefix while the CLI flag is converted into the config section
+(`_url` in [`src/aiperf/config/flags/_converter_telemetry.py`](https://github.com/ai-dynamo/aiperf/blob/main/src/aiperf/config/flags/_converter_telemetry.py)),
+and a missing `/metrics` path suffix is appended later by
+`GPUTelemetryManager._normalize_dcgm_url`. An item with neither `http` nor a
+`:` in it is rejected as an invalid `--gpu-telemetry` value rather than
+treated as a bare hostname.
+
+There is **no `gpuTelemetry.*` section in the Helm chart**. Endpoint
+configuration is a per-run CLI flag, not a cluster-wide operator setting.
+
+## Sidecar container
+
+When `gpu_telemetry_enabled=True`, the JobSet builder injects a dedicated
+`gpu-telemetry-manager` container into the controller pod via
+`_create_optional_manager_containers` in
+[`src/aiperf/kubernetes/jobset.py`](https://github.com/ai-dynamo/aiperf/blob/main/src/aiperf/kubernetes/jobset.py).
+It runs the `GPUTelemetryManager` service from
+[`src/aiperf/gpu_telemetry/manager.py`](https://github.com/ai-dynamo/aiperf/blob/main/src/aiperf/gpu_telemetry/manager.py).
+
+| Property | Value | Source |
+|---|---|---|
+| Container name | `gpu-telemetry-manager` | `Containers.GPU_TELEMETRY_MANAGER` |
+| Service type | `gpu_telemetry_manager` | plugin registry (`plugins.yaml`) |
+| Health port | `8086` (`GPU_TELEMETRY_MANAGER_HEALTH`) | `_PortSettings` |
+| Default CPU request/limit | `25m` | `_K8sEnvironment.GPU_TELEMETRY_MANAGER` |
+| Default memory request/limit | `192Mi` | `_K8sEnvironment.GPU_TELEMETRY_MANAGER` |
+| Collection interval | `333ms` (~3Hz) | `Environment.GPU.COLLECTION_INTERVAL` |
+
+Override resource limits with environment variables on the operator (or on
+a direct-mode controller pod):
+
+- `AIPERF_K8S_GPU_TELEMETRY_MANAGER_CPU=500m`
+- `AIPERF_K8S_GPU_TELEMETRY_MANAGER_MEMORY=1Gi`
+
+The scrape interval applies to every DCGM endpoint and is overridable via
+`AIPERF_GPU_COLLECTION_INTERVAL`.
+
+## Ingest path into the benchmark report
+
+The sidecar does not accumulate anything itself: every scrape is pushed to
+`RecordsManager` as a `TelemetryRecordsMessage` on the records PUSH socket,
+and `RecordsManager` owns the GPU telemetry accumulator. Lifecycle commands
+from `SystemController` drive the boundaries:
+
+1. **`PROFILE_CONFIGURE`** — `GPUTelemetryManager` resolves endpoints, probes
+   reachability, initializes each reachable collector, takes one pre-warmup
+   baseline scrape, and publishes a `TelemetryStatusMessage` (including
+   `endpoints_configured` / `endpoints_reachable`) back to the controller.
+2. **`PROFILE_START`** — collectors start and begin periodic scrapes at
+   `COLLECTION_INTERVAL`; each scrape is pushed to `RecordsManager` as it
+   happens.
+3. **`PhaseBaselineRequestMessage` (profiling phase boundary)** — the timing
+   service's phase publisher broadcasts this message; `GPUTelemetryManager`
+   handles it through `BaselineCollectorMixin`, which calls the manager's
+   `collect_baseline` and forces a boundary scrape so counter deltas have a
+   sample sitting right at the post-warmup boundary rather than relying on
+   whichever periodic scrape happened to land last. Capture is best-effort —
+   a failure is logged as a warning, never fatal.
+4. **`PROFILE_COMPLETE`** — forces a final scrape, stops collectors, then
+   pushes one terminal `TelemetryRecordsMessage` with
+   `collection_complete=True` so `RecordsManager` knows no further telemetry
+   records can follow.
+5. **`RecordsManager`** — exports the accumulated telemetry over the
+   profiling-phase window (plus `Environment.GPU.FINAL_SCRAPE_GRACE_NS` of
+   trailing grace so the final scrape is included) and publishes exactly one
+   `ProcessTelemetryResultMessage` carrying a `ProcessTelemetryResult`.
+6. **`SystemController._on_process_telemetry_result_message`** — receives the
+   published message (see
+   [`src/aiperf/controller/system_controller.py`](https://github.com/ai-dynamo/aiperf/blob/main/src/aiperf/controller/system_controller.py)),
+   overwrites `endpoints_configured` / `endpoints_successful` on the summary
+   with the values it recorded from the earlier `TelemetryStatusMessage`, and
+   stores the results for the unified export. `_check_and_trigger_shutdown`
+   waits for every registered result domain (profile records, telemetry,
+   server metrics, accuracy) before triggering the final export.
+7. **Export** — the accumulator's results are written into the top-level
+   `telemetry_data` block of `profile_export_aiperf.json` (shape shown in the
+   [general tutorial](../tutorials/gpu-telemetry.md#example-json-export))
+   and, separately, streamed per-record to `gpu_telemetry_export.jsonl`
+   via the `gpu_telemetry_jsonl_writer` plugin
+   (`src/aiperf/gpu_telemetry/jsonl_writer.py`).

+
+## Recipes
+
+### Minimal Kubernetes run with one in-cluster DCGM endpoint
+
+```bash
+aiperf kube profile \
+    --model Qwen/Qwen3-0.6B \
+    --endpoint-type chat \
+    --endpoint /v1/chat/completions \
+    --streaming \
+    --url dynamo-frontend.inference.svc.cluster.local:8000 \
+    --concurrency 32 \
+    --request-count 1024 \
+    --gpu-telemetry \
+        http://dcgm-exporter.gpu-operator.svc.cluster.local:9400/metrics
+```
+
+### Multi-node DCGM
+
+Each node's dcgm-exporter DaemonSet typically exposes a per-node endpoint
+through a headless Service (one URL per node) or via a single Service that
+load-balances across nodes (one logical URL, aggregated). AIPerf treats
+each URL as an independent scrape target — supply them all:
+
+```bash
+--gpu-telemetry \
+    http://dcgm-node01.gpu-operator.svc.cluster.local:9400/metrics \
+    http://dcgm-node02.gpu-operator.svc.cluster.local:9400/metrics \
+    http://dcgm-node03.gpu-operator.svc.cluster.local:9400/metrics
+```
+
+GPU indices and hostnames in the exported report disambiguate metrics
+from different endpoints.
+
+### Disable on a CPU-only cluster
+
+```bash
+aiperf kube profile --model ... --no-gpu-telemetry
+```
+
+### Verify the sidecar is present
+
+After submitting the job, inspect the controller pod:
+
+```bash
+kubectl -n my-benchmarks get pod -l aiperf.nvidia.com/job-id=<job-id> \
+    -o jsonpath='{.items[*].spec.containers[*].name}'
+```
+
+Look for `gpu-telemetry-manager` in the listed container names. If it is
+missing, the JobSet was built with `gpu_telemetry_enabled=False` — either
+`--no-gpu-telemetry` was passed or the CR spec was overridden.
+
+### Verify reachability from inside the controller pod
+
+```bash
+kubectl -n my-benchmarks exec -c control-plane <controller-pod> -- \
+    curl -s -o /dev/null -w '%{http_code}\n' \
+    http://dcgm-exporter.gpu-operator.svc.cluster.local:9400/metrics
+```
+
+A `200` confirms the URL is reachable from the pod network. The
+`gpu-telemetry-manager` container will do the same probe during
+`PROFILE_CONFIGURE` and report the result via `TelemetryStatus`.
+
+## Troubleshooting
+
+### No `telemetry_data` in the exported report
+
+Either no endpoints were reachable, no records were produced before
+`PROFILE_COMPLETE`, or the sidecar was disabled. Check in order:
+
+1. Did the run include the `gpu-telemetry-manager` container?
+   (`kubectl get pod ... -o jsonpath='{.spec.containers[*].name}'`)
+2. Are the URLs resolvable from inside the controller pod network?
+   DNS must resolve the DCGM Service, and the pod's NetworkPolicy must
+   permit egress to the `:9400` target.
+3. The defaults `localhost:9400` / `localhost:9401` are always tried;
+   in-cluster they will fail probes silently — that is expected. Look
+   for the URL you passed via `--gpu-telemetry` in the status line.
+
+### Endpoints listed as configured but not as successful
+
+`ProcessTelemetryResult.summary.endpoints_configured` is a display-filtered
+list, not every URL attempted: it is every URL you passed via
+`--gpu-telemetry` plus only those built-in defaults that turned out to be
+reachable (`GPUTelemetryManager._compute_endpoints_for_display`). Unreachable
+defaults are deliberately omitted so in-cluster runs don't show two dead
+`localhost` rows. `endpoints_successful` includes only the endpoints that
+responded during the configuration probe. A URL in the first but not the
+second means the probe failed — typically DNS, NetworkPolicy, or the exporter
+not listening on the expected path. DCGM Exporter serves `/metrics` by
+default; verify the path suffix matches.
+
+### Counter metrics look wrong (energy, XID, violations)
+
+Counter-style DCGM metrics are reported as a single delta: the last valid
+in-window sample minus the last valid sample strictly *before* the profiling
+window (`to_metric_result_filtered` in
+[`src/aiperf/common/models/telemetry_models.py`](https://github.com/ai-dynamo/aiperf/blob/main/src/aiperf/common/models/telemetry_models.py)).
+Negative deltas are clamped to `0.0` so a DCGM restart mid-run reads as no
+movement rather than as a large negative number. If the phase-boundary
+baseline scrape fails for an endpoint, the reference falls back to whichever
+periodic scrape landed most recently before the boundary, so at most one
+collection interval of warmup tail leaks into the value.
+`BaselineCollectorMixin` logs
+`Baseline capture failed for phase '<name>' <kind>: ...` at WARN level
+when that happens — grep the `gpu-telemetry-manager` container logs for
+`Baseline capture failed`.
+
+### Memory estimator shows `disabled (no DCGM URLs)`
+
+The memory estimator reports zero GPU-telemetry memory usage when
+`gpu_telemetry.enabled=False` OR `gpu_telemetry.urls` is empty (defaults
+never count as URLs for estimation purposes — see
+`_derive_gpu_telemetry` in
+[`src/aiperf/kubernetes/_memory_estimator/params.py`](https://github.com/ai-dynamo/aiperf/blob/main/src/aiperf/kubernetes/_memory_estimator/params.py)).
+That is a display heuristic, not a runtime gate: the sidecar still runs
+and still tries the built-in defaults. To prevent it from running at
+all, use `--no-gpu-telemetry`.

+
+# Config Init and Manifest Generation
+
+AIPerf ships two offline commands that let you author benchmarks as files
+before touching a cluster:
+
+- `aiperf kube init` — scaffold a starter YAML config (an `AIPerfJob` CR
+  template) that you can edit by hand.
+- `aiperf kube generate` — render the finished Kubernetes manifests
+  (either an `AIPerfJob` CR or a raw `Namespace + RBAC + ConfigMap +
+  JobSet` bundle) to stdout or a file, with no cluster calls.
+
+Both commands are the foundation of a GitOps workflow: you commit the
+rendered YAML to a repo, open a PR for review, and then `kubectl apply`
+the reviewed file. No cluster access is required to run either command.
+
+## `aiperf kube init`
+
+### Purpose
+
+`init` renders one of the bundled AIPerf config templates
+(`src/aiperf/config/templates/`, the same library `aiperf config init`
+uses), wraps it in an `AIPerfJob` CR shell, and writes the result to
+stdout (or to a file with `--output`). The default template
+(`minimal`) covers only the required fields; commented-out blocks for
+deployment options, pod customization, and Kueue scheduling are
+appended to every template so you can uncomment what you need.
+
+### CLI reference
+
+| Flag | Type | Default | Description |
+| --- | --- | --- | --- |
+| `-t`, `--template` | `str` | `minimal` | Template name to render (e.g. `minimal`, `goodput_slo`). Run with `--list` to see all bundled templates. |
+| `-l`, `--list` | flag | `false` | List all available templates grouped by category. |
+| `-s`, `--search` | `str` | `None` | Search templates by keyword (matches name, description, tags, features). |
+| `-c`, `--category` | `str` | `None` | Filter template listings by category (substring match). |
+| `-v`, `--verbose` | flag | `false` | Show tags, features, and difficulty in template listings. |
+| `--model` | `str` | `None` | Override the model name in the generated config. |
+| `--url` | `str` | `None` | Override the endpoint URL in the generated config. |
+| `-o`, `--output` | path | `None` (stdout) | Output file path. When set, writes to disk; prompts before overwriting an existing file. |
+| `--job-name` | `str` | `my-benchmark` | Value for `metadata.name` on the generated `AIPerfJob`. |
+
+With no arguments, `init` renders the `minimal` template (bundled in
+`src/aiperf/config/templates/`) wrapped in an `AIPerfJob` CR shell. Use
+`--list` / `--search` / `--category` to browse the other bundled templates
+and `--template` to pick one.
+
+### Examples
+
+```bash
+# Print template to stdout, byte-for-byte (safe to pipe into kubectl or a file)
+aiperf kube init
+
+# Write to a file
+aiperf kube init --output benchmark.yaml
+
+# Write and confirm overwrite if benchmark.yaml already exists
+aiperf kube init -o benchmark.yaml
+```
+
+### Template walkthrough
+
+The scaffold is an `AIPerfJob` CR. Below is the template as emitted by
+`init`; usage comments at the top are substituted with the filename
+you wrote to (defaulting to `benchmark.yaml`).
+
+```yaml
+# AIPerf Kubernetes Benchmark - AIPerfJob Custom Resource
+#
+# Usage (CLI):
+#   aiperf kube profile --config benchmark.yaml --image <your-image>
+#
+# Usage (GitOps / operator):
+#   kubectl apply -f benchmark.yaml
+#
+# This file defines an AIPerfJob CR. When using the CLI, --image and other
+# Kubernetes flags are still required; benchmark config comes from this file.

+  #       mountPath: /root/.cache/huggingface
+
+  # === Kueue Scheduling ===
+  # scheduling:

+  #   priorityClass: high-priority
+```
+
+The `minimal` template uses AIPerf's shorthand forms — `model:` (scalar),
+`endpoint.url:`, `dataset:` (singular), and a flat `phases:` block — which
+AIPerf auto-expands to their canonical list forms at load time. Point
+`model:` and `endpoint.url:` at your real model and server before running
+anything else. A realistic edit looks like:
+
+```yaml
+benchmark:
+  model: meta-llama/Llama-3.1-8B-Instruct
+  endpoint:
+    url: http://llm-service.default.svc:8000/v1
+```
+
+To scaffold a different starting point (goodput SLOs, multi-phase load,
+etc.), pick another bundled template with `aiperf kube init --list` and
+`--template <name>`.
+
+### Relationship with other commands
+
+The file `init` writes is the same format accepted by every other
+config-consuming command:
+
+| Command | What it does with the file |
+| --- | --- |
+| `aiperf kube validate` | Parses and schema-checks the config without any cluster call. |
+| `aiperf kube generate` | Renders the final manifests from the config. |
+| `aiperf kube profile` | Applies and runs the benchmark on the cluster. |
+
+`aiperf kube preflight` is deliberately absent from that table: it does
+not read a config file at all. It takes `--image`, `--image-pull-secrets`,
+`--secrets`, `--endpoint-url`, `--workers`, and `--output` (plus the shared
+namespace/kubeconfig flags) and probes the cluster with them.
+
+When invoking `profile` or `generate`, CLI flags for Kubernetes
+settings (`--image`, `--namespace`, `--total-workers`, etc.) still
+overlay the CR — the file owns the benchmark config, the flags own the
+deployment shape.
+
+## `aiperf kube generate`
+
+### Purpose
+
+`generate` renders the YAML that would otherwise be submitted by
+`profile`, and writes it to stdout. It does not connect to a cluster
+and does not require the AIPerf operator to be installed.
+
+It has two mutually exclusive modes:
+
+- `--operator` — emits one `AIPerfJob` CR document for a single run, or one
+  `AIPerfSweep` CR document when the config has `sweep:` or requests multiple
+  trials through `multiRun.numRuns > 1` / `multiRun.convergence`. Requires the
+  AIPerf operator to be installed on the target cluster for `kubectl apply` to
+  do anything useful.
+- `--no-operator` — emits multiple documents separated by `---`:
+  `Namespace`, `Role`, `RoleBinding`, `ConfigMap`, and `JobSet`. Works
+  on any cluster with the JobSet controller (no operator required). This mode
+  executes exactly one benchmark run; configs with `sweep:` or multi-run
+  orchestration must use `--operator` or `aiperf kube sweep`.
+
+One of the two flags must be specified; the command exits with an
+error if neither (or both) is given.
+
+### CLI reference
+
+`generate` accepts the full set of `aiperf` benchmark flags plus the
+`Kubernetes` / `KubeOptions` group. The mode flags are:
+
+| Flag | Description |
+| --- | --- |
+| `--operator` | Emit one `AIPerfJob` or `AIPerfSweep` CR, selected from the resolved config. |
+| `--no-operator` | Emit raw manifests (Namespace + Role + RoleBinding + ConfigMap + JobSet). |
+
+Relevant `KubeOptions` flags that shape the rendered manifests:
+
+| Flag | Default | Description |
+| --- | --- | --- |
+| `--image` | config value, installed chart default (`--operator`), or `nvcr.io/nvidia/aiperf:latest` (`--no-operator`) | Explicit container-image override. An image authored in workload YAML remains authoritative when omitted. |
+| `--image-pull-policy` | `None` | `Always` / `IfNotPresent` / `Never`. |
+| `--name` | auto-generated | Human-readable DNS label, max 40 chars. |
+| `--namespace` | kubeconfig context namespace | Target namespace; required when your context does not set one. |
+| `--total-workers` | `10` | Total workers; divided across pods by `workers_per_pod`. |
+| `--ttl-seconds` | `300`. In `--no-operator` mode, when the flag is not set explicitly, `generate` overrides the default to `AIPERF_K8S_JOBSET_DIRECT_MODE_TTL_SECONDS` (8h / 28800s) so pods stay alive for `aiperf kube results`. | Seconds to keep pods after completion. |
+| `--node-selector`, `--tolerations` | `{}`, `[]` | Pod placement. |
+| `--queue-name`, `--priority-class` | `None` | Kueue scheduling. |
+| `--annotations`, `--labels` | `{}` | Extra pod metadata. |
+| `--image-pull-secrets`, `--env-vars`, `--env-from-secrets`, `--secret-mounts`, `--service-account` | `[]` / `{}` / `None` | Secrets and credentials. |
+
+Output always goes to **stdout**. Redirect it to capture to a file; a
+memory-usage estimate is printed to **stderr** so it does not
+contaminate the YAML stream.
+
+### Examples
+
+```bash
+# Render an AIPerfJob CR (or AIPerfSweep for sweep/multi-run config)
+aiperf kube generate --operator \
+  --model Qwen/Qwen3-0.6B \
+  --url http://server:8000 \
+  --image aiperf:latest
+
+# Render raw manifests
+aiperf kube generate --no-operator \
+  --model Qwen/Qwen3-0.6B \
+  --url http://server:8000 \
+  --image aiperf:latest
+
+# Pipe straight to kubectl
+aiperf kube generate --no-operator \
+  --config benchmark.yaml --image aiperf:latest \
+  | kubectl apply -f -
+
+# Capture to disk for review
+aiperf kube generate --operator \
+  --config benchmark.yaml --image aiperf:latest \
+  > benchmarks/nightly-llama3.yaml
+```
+
+### What's in the rendered manifest
+
+Operator mode (`--operator`) emits one document:
+
+- `aiperf.nvidia.com/v1alpha1` `AIPerfJob` — for a single-run config, with
+  `spec.benchmark` holding the benchmark body and deployment fields (`image`,
+  `podTemplate`, `scheduling`, `connectionsPerWorker`, etc.) at the top of
+  `spec`.
+- `aiperf.nvidia.com/v1alpha1` `AIPerfSweep` — when the resolved config has a
+  parameter `sweep:` or needs multiple trials. A multi-run-only config receives
+  a one-cell `base` scenario so the sweep controller executes the canonical
+  trial plan without inventing a parameter dimension.
+
+Direct mode (`--no-operator`) emits, in order:
+
+Direct mode accepts only a single-run config. It fails before writing manifests
+when the resolved config requires parameter-sweep or multi-run orchestration,
+because a raw JobSet has no sweep-controller owner and would otherwise execute
+only the base cell.
+
+The target namespace is not emitted -- it must already exist. Creating it
+would demand cluster-scoped namespace-create rights that most benchmark
+runners do not have.
+
+1. `rbac.authorization.k8s.io/v1` `Role` — grants the benchmark pods
+   get/list/watch on `configmaps`, `services`, `endpoints`, `events`,
+   `pods`, `pods/log`, `jobs`, and `jobsets/status`, plus
+   get/list/watch/**patch** on `jobsets` and on `aiperfjobs` /
+   `aiperfjobs/status`. `patch` is the only write verb; the pods share one
+   ServiceAccount, so nothing here can create, replace, or delete an object.
+2. `rbac.authorization.k8s.io/v1` `RoleBinding` — binds the Role to
+   the pods' ServiceAccount (default: `default`).
+3. `v1` `ConfigMap` named `aiperf-<job_id>-config`, containing a single
+   key `run_config.json` with the fully materialized `BenchmarkRun`
+   (1 MiB hard cap — `generate` validates this before emitting).
+4. `jobset.x-k8s.io/v1alpha2` `JobSet` named `aiperf-<job_id>` — two
+   replicated jobs, one `controller` pod and N `workers` pods. GPU
+   telemetry and server metrics are optional extra containers inside the
+   controller pod, not separate pods.
+
+Worker count is derived from the max phase concurrency and
+`connections_per_worker`; `generate` runs the same
+`apply_k8s_runtime_config` + `apply_worker_config` passes that
+`profile` uses, so the rendered JobSet has the correct number of
+replicas baked in.
+
+### GitOps recipe
+
+```bash
+# 1. scaffold (once)
+aiperf kube init -o benchmarks/nightly-llama3.yaml
+$EDITOR benchmarks/nightly-llama3.yaml
+
+# 2. render to a reviewable artifact
+aiperf kube generate --operator \
+  --config benchmarks/nightly-llama3.yaml \
+  --image aiperf:latest \
+  --total-workers 20 \
+  --namespace bench-prod \
+  > manifests/nightly-llama3.yaml
+
+# 3. commit + PR
+git add benchmarks/nightly-llama3.yaml manifests/nightly-llama3.yaml
+git commit -s -m "Add nightly Llama3 benchmark"
+# open PR, get reviews
+
+# 4. merge + apply
+kubectl apply -f manifests/nightly-llama3.yaml
+```
+
+The source config and the rendered manifest are both tracked; the
+rendered file is the one the cluster sees, so reviewers can inspect
+the exact JobSet spec, RBAC rules, and ConfigMap payload that will be
+applied.
+
+### Preview vs. `profile --dry-run`
+
+Both `generate` and `profile --dry-run` run entirely offline and
+neither submits anything to the cluster. The difference is output:
+
+| Behaviour | `aiperf kube generate` | `aiperf kube profile --dry-run` |
+| --- | --- | --- |
+| Cluster calls | None | None |
+| AIPerfJob CR output | Yes (`--operator`) | Yes (printed as JSON, operator path) |
+| Raw manifests output | Yes (`--no-operator`, YAML) | Yes (YAML, direct path / `--no-operator`) |
+| Memory estimate | Yes (stderr) | Yes (stderr) |
+| Intended use | Stable GitOps authoring and review | Exact preview of the corresponding `profile` path |
+
+Both commands keep stdout machine-readable and safe to pipe: the payload is
+written verbatim, so a long image reference or endpoint URL is never wrapped
+into an invalid document when stdout is a pipe or file. Use `generate` when the
+YAML itself is the stable artifact you want to commit or diff. Use
+`profile --dry-run` to preview the exact operator or direct deployment path
+without actually running it.
+
+## Validation chain
+
+The typical end-to-end flow is:
+
+```mermaid
+flowchart LR
+    init[aiperf kube init] --> edit[Edit YAML]
+    edit --> validate[aiperf kube validate]
+    validate --> preflight[aiperf kube preflight]
+    preflight --> choice{GitOps?}
+    choice -- "Yes" --> generate[aiperf kube generate]
+    generate --> kubectl[kubectl apply -f ...]
+    choice -- "No" --> profile[aiperf kube profile]
+```
+
+Each step is independent and idempotent:
+
+1. **`init`** writes the starter file.
+2. **Edit** — adjust models, endpoint, phases, pod template.
+3. **`validate`** — schema-check the file; purely offline.
+4. **`preflight`** — verify cluster reachability and endpoint health.
+5a. **GitOps path**: **`generate`** → commit → `kubectl apply`.
+5b. **CLI path**: **`profile`** — deploy and stream progress directly.
+
+For long-lived recurring benchmarks that are reviewed and versioned,
+prefer the GitOps path. For ad-hoc experiments, run `profile`
+directly — it performs the same manifest generation under the hood.

+# Kueue Integration
+
+AIPerf integrates with [Kueue](https://kueue.sigs.k8s.io/) to provide
+gang-scheduling, quota management, and prioritization for benchmark JobSets.
+This page explains what Kueue buys you, how to install and configure it, and
+how AIPerfJobs bind to Kueue resources.
+
+---
+
+## What Kueue Is
+
+Kueue is a Kubernetes-native job queueing system maintained by the upstream
+`kubernetes-sigs` project. It sits between job controllers (JobSet, Job,
+`RayJob`, etc.) and the cluster scheduler, admitting workloads only when the
+cluster has enough free capacity in a named *ClusterQueue* (cluster-scoped
+quota pool) addressed through a *LocalQueue* (namespace-scoped handle). A
+workload either runs in full or stays suspended; Kueue never schedules a
+partial JobSet.
+
+Useful upstream entry points:
+
+- [Overview](https://kueue.sigs.k8s.io/docs/overview/)
+- [Concepts: ClusterQueue, LocalQueue, ResourceFlavor](https://kueue.sigs.k8s.io/docs/concepts/)
+- [JobSet integration](https://kueue.sigs.k8s.io/docs/tasks/run/jobsets/)
+- [Workload Priority Classes](https://kueue.sigs.k8s.io/docs/concepts/workload_priority_class/)
+
+---
+
+## Why Use Kueue With AIPerf
+
+An AIPerf benchmark runs as a JobSet with two replicated jobs: one
+`controller` pod (control plane, records manager, results sidecar, and the
+optional telemetry containers) and N `workers` pods. All pods must start
+together, or the controller sits idle while workers slowly trickle in and
+the benchmark either fails or produces misleading numbers.
+
+Kueue solves three problems that matter for benchmark campaigns:
+
+- **Gang scheduling.** Kueue suspends the JobSet until the cluster can admit
+  *every* pod at once. On a mixed cluster, this prevents a half-scheduled
+  run that would skew latency metrics.
+- **Priority and preemption across campaigns.** A
+  `WorkloadPriorityClass` lets a smoke-test job jump the queue ahead of a
+  long soak-test, or lets a tenant's urgent run preempt an idle reservation.
+- **Fair sharing across teams.** A single ClusterQueue with `borrowingLimit`
+  rules lets multiple namespaces share GPU capacity without one team
+  starving another — useful when several groups run benchmarks on the same
+  cluster.
+
+Without Kueue, AIPerfJobs are submitted directly to the JobSet controller
+and compete for nodes using default Kubernetes scheduling.
+
+---
+
+## Install
+
+AIPerf does not vendor or pin a Kueue release; install any version whose
+`kueue.x-k8s.io/v1beta1` API AIPerf targets (`LocalQueue`, `ClusterQueue`,
+`ResourceFlavor`, `WorkloadPriorityClass`). Follow the upstream
+[installation guide](https://kueue.sigs.k8s.io/docs/installation/). A typical
+install applies the released manifest bundle:
+
+```bash
+kubectl apply --server-side -f \
+  https://github.com/kubernetes-sigs/kueue/releases/latest/download/manifests.yaml
+```
+
+The operator runs a `Kueue Queue` preflight check during reconcile that
+verifies the Kueue CRDs are present and that any referenced LocalQueue
+actually exists (see `src/aiperf/operator/preflight/_infra.py`). If Kueue is
+not installed and no queue was requested, the check is marked `SKIP` and
+AIPerfJobs run without gang-scheduling. If an explicit queue was requested,
+the check fails because the resulting suspended JobSet would otherwise never
+be admitted. This check is operator-side only — the client-side
+`aiperf kube preflight` command does not include it.
+
+---
+
+## Configuring a ClusterQueue and LocalQueue
+
+A minimal setup for a benchmark cluster looks like this. Adjust the
+`nominalQuota` values to match your real GPU inventory.
+
+```yaml
+apiVersion: kueue.x-k8s.io/v1beta1
+kind: ResourceFlavor
+metadata:
+  name: default-flavor
+---
+apiVersion: kueue.x-k8s.io/v1beta1
+kind: ClusterQueue
+metadata:
+  name: aiperf-cluster-queue
+spec:
+  namespaceSelector: {}
+  resourceGroups:
+    - coveredResources: ["cpu", "memory", "nvidia.com/gpu"]
+      flavors:
+        - name: default-flavor
+          resources:
+            - name: "cpu"
+              nominalQuota: 256
+            - name: "memory"
+              nominalQuota: 1024Gi
+            - name: "nvidia.com/gpu"
+              nominalQuota: 16
+---
+apiVersion: kueue.x-k8s.io/v1beta1
+kind: LocalQueue
+metadata:
+  name: aiperf-queue
+  namespace: my-benchmarks
+spec:
+  clusterQueue: aiperf-cluster-queue
+```
+
+Optional: add a `WorkloadPriorityClass` for high-priority runs.
+
+```yaml
+apiVersion: kueue.x-k8s.io/v1beta1
+kind: WorkloadPriorityClass
+metadata:
+  name: aiperf-high
+value: 1000
+description: "High-priority AIPerf benchmark runs"
+```
+
+---
+
+## Binding an AIPerfJob to a Queue
+
+AIPerf stamps the `kueue.x-k8s.io/queue-name` label onto the JobSet (and
+starts it suspended) whenever it can resolve a queue name from either
+`spec.scheduling.queueName` or the operator-side
+`AIPERF_K8S_JOBSET_KUEUE_DEFAULT_QUEUE_NAME` env var. Kueue's own
+namespace-annotation default works differently.
+
+### 1. CLI flags
+
+The `aiperf kube profile` command (and every other submit subcommand)
+accepts `--queue-name` and `--priority-class`:
+
+```bash
+aiperf kube profile \
+  --url http://my-server:8000/v1 \
+  --model Qwen/Qwen3-0.6B \
+  --queue-name aiperf-queue \
+  --priority-class aiperf-high
+```
+
+These flags live in the `Kubernetes Scheduling` group and are defined on
+`KubeOptions` in `src/aiperf/config/kube.py`.
+
+### 2. CR YAML
+
+Set the same fields directly in the AIPerfJob spec under `scheduling`:
+
+```yaml
+apiVersion: aiperf.nvidia.com/v1alpha1
+kind: AIPerfJob
+metadata:
+  name: latency-sweep-7f2a
+  namespace: my-benchmarks
+spec:
+  scheduling:
+    queueName: aiperf-queue
+    priorityClass: aiperf-high
+  benchmark:
+    models: ["Qwen/Qwen3-0.6B"]
+    endpoint:
+      urls: ["http://dynamo-agg-frontend.dynamo-server.svc:8000/v1"]
+      streaming: true
+    datasets:
+      - name: main
+        type: synthetic
+        entries: 1000
+    phases:
+      - name: profiling
+        type: concurrency
+        concurrency: 50
+        requests: 500
+```
+
+### 3. Cluster-wide default via Helm
+
+The `aiperf-operator` Helm chart exposes a `kueue.defaultQueueName` value
+(see `deploy/helm/aiperf-operator/values.yaml`). When set, the chart sets
+`AIPERF_K8S_JOBSET_KUEUE_DEFAULT_QUEUE_NAME` on the operator container so
+AIPerf's own manifest builder applies the queue label and starts the JobSet
+suspended.
+
+```yaml
+# values.yaml
+kueue:
+  defaultQueueName: aiperf-queue
+```
+
+Kueue also honours a `kueue.x-k8s.io/default-queue-name` annotation on the
+namespace, which you apply yourself with `kubectl annotate` (see
+Troubleshooting below). AIPerf's own manifest builder does **not** read that
+annotation: `AIPerfJobSetSpec._resolved_queue_name` in
+`src/aiperf/kubernetes/jobset.py` consults only
+`spec.scheduling.queueName` and the `AIPERF_K8S_JOBSET_KUEUE_DEFAULT_QUEUE_NAME`
+env var, so the annotation alone does not make AIPerf add the queue label or
+start the JobSet suspended. Operator preflight does read it, and treats an
+annotated namespace as a satisfied queue configuration. To make Kueue
+gang-scheduling default-on from AIPerf's side, set
+`AIPERF_K8S_JOBSET_KUEUE_DEFAULT_QUEUE_NAME` (and optionally
+`AIPERF_K8S_JOBSET_KUEUE_DEFAULT_PRIORITY_CLASS`) on the operator
+deployment.
+
+The chart can also provision the queue objects themselves instead of you
+applying the YAML above by hand. Set `kueue.createQueues=true` and the chart
+renders a `ResourceFlavor`, `ClusterQueue`, and `LocalQueue` from
+`deploy/helm/aiperf-operator/templates/kueue-queues.yaml`, using
+`kueue.flavorName`, `kueue.clusterQueueName`, `kueue.localQueueName`, and the
+`kueue.resources` quota map (`cpu`, `memory`, and an optional `gpu` entry that
+is skipped when empty). It is off by default so the chart renders on clusters
+without Kueue CRDs, and even when enabled the template is additionally gated
+on the `kueue.x-k8s.io/v1beta1` API being present. When `defaultQueueName` is
+left empty and `createQueues=true`, the operator's default queue falls back to
+`kueue.localQueueName`.
+
+> **WARNING:** `kueue.createQueues=true` creates the `LocalQueue` in the
+> chart's release namespace (`aiperf-system` by default), *not* in the
+> namespaces your benchmarks run in. A `LocalQueue` is namespace-scoped and
+> Kueue only admits a workload whose `kueue.x-k8s.io/queue-name` label
+> resolves to a `LocalQueue` **in the workload's own namespace**. A benchmark
+> submitted into `my-benchmarks` with the chart's queue name therefore sits in
+> `Queued` forever with no error: the JobSet stays suspended and no pod is
+> ever created.
+>
+> Create one `LocalQueue` per benchmark namespace, pointing at the shared
+> `ClusterQueue` the chart made:
+>
+> ```bash
+> kubectl create -n my-benchmarks -f - <<'EOF'
+> apiVersion: kueue.x-k8s.io/v1beta1
+> kind: LocalQueue
+> metadata:
+>   name: aiperf-queue
+>   namespace: my-benchmarks
+> spec:
+>   clusterQueue: aiperf-cluster-queue
+> EOF
+> ```
+>
+> The `ClusterQueue` and `ResourceFlavor` are cluster-scoped, so those the
+> chart really can own for you; only the `LocalQueue` handle has to be
+> repeated per namespace. A missing `LocalQueue` does not surface as a CLI
+> error — the JobSet simply stays suspended indefinitely — so create the
+> per-namespace `LocalQueue` before submitting your first benchmark.
+

+## What the Operator Does
+
+```mermaid
+flowchart LR
+  CLI["aiperf kube profile<br/>--queue-name aiperf-queue"] --> CR["AIPerfJob CR<br/>spec.scheduling.queueName"]
+  CR --> OP["Operator<br/>handlers/create.py"]

+  JS --> MON["Operator monitor<br/>Phase: QUEUED"]
+  RUN --> MON2["Operator monitor<br/>Phase: INITIALIZING"]
+```
+
+Concretely:
+
+1. `src/aiperf/kubernetes/jobset.py` translates
+   `spec.scheduling.queueName` and `priorityClass` into JobSet labels
+   (`kueue.x-k8s.io/queue-name`, `kueue.x-k8s.io/priority-class`) via
+   `KueueLabels` in `src/aiperf/kubernetes/constants.py`.
+2. When a `queueName` is set, the JobSet is created with
+   `spec.suspend: true`. Kueue unsuspends it once the `Workload` it
+   generates has been admitted.
+3. `src/aiperf/operator/handlers/monitor.py::_handle_kueue_suspension`
+   watches the JobSet's `spec.suspend` field. While the JobSet is suspended
+   and carries a Kueue queue label, the operator surfaces the
+   `QUEUED` phase on the AIPerfJob status (see `Phase.QUEUED` in
+   `src/aiperf/kubernetes/phase.py`).
+4. Once Kueue admits the workload, the JobSet unsuspends, pods start, and
+   the monitor transitions the phase to `INITIALIZING` -> `RUNNING`.
+
+You can observe admission directly with `kubectl`:
+
+```bash
+kubectl get workloads -n my-benchmarks
+kubectl get aiperfjob latency-sweep-7f2a -n my-benchmarks \
+  -o jsonpath='{.status.phase}'
+```
+
+---
+
+## Troubleshooting
+
+**Job stuck in `QUEUED` phase.** Kueue has accepted the Workload but has
+not admitted it. Check in order:
+
+1. `kubectl describe workload -n my-benchmarks` — look at the
+   `QuotaReserved` and `Admitted` conditions. The message usually names
+   the resource that is over quota.
+2. `kubectl get clusterqueue aiperf-cluster-queue -o yaml` — compare
+   `spec.resourceGroups.*.nominalQuota` to what the JobSet requests. Each
+   worker pod requests the `AIPERF_K8S_WORKER_POD_CPU` /
+   `AIPERF_K8S_WORKER_POD_MEMORY` budget (default `3350m` / `6Gi`), split
+   across its containers, and `spec.resourceMode` decides whether limits are
+   emitted alongside requests; see
+   [`configuration.md`](configuration.md) for defaults.
+3. Another admitted Workload may be holding the quota. List active
+   workloads with
+   `kubectl get workloads -A -o wide` and cancel stale ones.
+
+**Operator preflight fails: `Kueue LocalQueue '<name>' not found`.** The
+resolved `scheduling.queueName` references a LocalQueue that does not exist
+in the target namespace. Either create it (see the YAML above) or drop the
+field. `_verify_kueue_local_queue` reports `FAIL` for both causes but names
+them separately: "Kueue is not installed, but LocalQueue '<name>' was
+explicitly requested" versus "Kueue LocalQueue '<name>' not found". The
+`SKIP` outcome comes from `_check_kueue_queue`, and only when no queue was
+requested at all.
+
+**Operator preflight warns: `Kueue is installed but no queue configured`.**
+Kueue is present on the cluster but the job bypasses it. Fix by either passing
+`--queue-name`, setting `spec.scheduling.queueName` in the CR, or adding
+the namespace default:
+
+```bash
+kubectl annotate namespace my-benchmarks \
+  kueue.x-k8s.io/default-queue-name=aiperf-queue

+
+`aiperf kube logs` fetches or streams container logs from a specific
+AIPerfJob. It targets the controller pod's service containers, the
+per-pod worker / record-processor containers, and the sidecars that
+surround them. Use it for post-mortem triage of a finished run, for live
+streaming during an active benchmark, or for bulk-dumping every pod's
+log to disk.
+
+Unlike `aiperf kube debug`, which is a one-shot diagnostic snapshot
+across an entire namespace, `logs` targets a single AIPerfJob and
+operates at container granularity.
+
+---
+
+## CLI reference
+
+```bash
+aiperf kube logs [JOB_ID] [OPTIONS]
+```
+
+| Flag / argument | Type | Default | Description |
+|---|---|---|---|
+| `JOB_ID` (positional) | `str` | last-deployed job | AIPerfJob ID — or an `AIPerfSweep` name, when combined with `-v` — to pull logs from. If omitted, falls back to the job ID stored on disk by the most recent `aiperf kube profile` / `aiperf kube sweep` invocation. |
+| `--container` | `str` | *(all containers on every pod)* | Restrict to a single container name. See the [container catalog](#container-catalog) below. |
+| `-f`, `--follow` | flag | `false` | Stream logs in real time. Only one target can be followed at a time; see [follow semantics](#follow-semantics). |
+| `--tail` | `int` | *(full log)* | Return only the last N lines. Combine with `-f` to start a stream at the tail. |
+| `-o`, `--output` | `Path` | *(stdout)* | Write logs to a directory instead of printing. See [bulk dump](#bulk-dump-to-disk). |
+| `-v`, `--variation` | `int` | unset | When `JOB_ID` names an `AIPerfSweep`, the child variation index (`0`..`199`). Resolves to `<sweep>-v<idx:02d>`. |
+| `-t`, `--trial` | `int` | unset | Trial index (`0`..`9`) within a sweep variation, resolving to `<sweep>-v<idx:02d>-t<trial>`. Requires `-v`. |
+| `--ignore-not-found` | flag | `false` | Exit `0` instead of `1` when the target benchmark does not exist. Mirrors `kubectl`'s flag of the same name. See [exit codes](#exit-codes). |
+| `-n`, `--namespace` | `str` | cached last-benchmark namespace, else the kubeconfig context namespace | Namespace that holds the AIPerfJob. Composite flag from `KubeManageOptions`. |
+| `--kubeconfig` | `str` | `$KUBECONFIG` / `~/.kube/config` | kubeconfig file to use. Composite flag from `KubeManageOptions`. |
+| `--kube-context` | `str` | current context | kubeconfig context to use. Composite flag from `KubeManageOptions`. |
+
+Job resolution works exactly like every other `aiperf kube` subcommand:
+if you omit `JOB_ID`, the CLI reads the last-benchmark cache
+(`~/.aiperf/last_kube_benchmark.json`) written by `aiperf kube profile`
+/ `aiperf kube sweep` and reuses that ID and namespace. `aiperf kube
+generate` does **not** write this cache — it never contacts the
+cluster. Supplying `--namespace` on the command line always overrides
+the cached namespace.
+
+---
+
+## Container catalog
+
+AIPerf pods run one process per container. Most names below are among the
+11 canonical container-name constants declared on
+`aiperf.kubernetes.constants.Containers` (see
+`src/aiperf/kubernetes/constants.py`); the `worker-<N>` and
+`record-processor-<N>` names are formed at runtime by indexing and are **not**
+declared constants. Feed any of them to `--container` verbatim.
+
+### Controller pod
+
+The controller pod runs between six and nine containers — seven with stock
+settings. `create_controller_containers` always emits the five control-plane
+services plus `results-sidecar`, prepends `event-bus-proxy` when
+`AIPERF_K8S_EVENT_BUS_SIDECAR_ENABLED` is true (the default), and appends the
+two optional managers only when their features are enabled:
+
+| Container | Purpose |
+|---|---|
+| `control-plane` | SystemController and orchestration logic. |
+| `event-bus-proxy` | XPUB/XSUB event-bus proxy sidecar. Isolates pub/sub forwarding from the SystemController event loop so large fan-ins of workers and record processors at startup do not starve the control plane. |
+| `dataset-manager` | Dataset generation and memory-map serving. |
+| `timing-manager` | Request scheduling and credit timing. |
+| `records-manager` | Metric record aggregation, export, and storage. |
+| `api` | HTTP + WebSocket API surface for monitoring, progress, and result artifacts. |
+| `results-sidecar` | Lightweight sidecar serving exported artifacts from `/results`; outlives the main controller on export so the operator can still download results. |
+| `gpu-telemetry-manager` | DCGM GPU metrics collection. Present only when GPU telemetry is enabled. |
+| `server-metrics-manager` | Prometheus server-side metrics scraping. Present only when server metrics are enabled. |
+
+### Worker pod
+
+Each worker pod runs three kinds of containers. The `<N>` indices are
+pod-local and start at `0`:
+
+| Container | Purpose |
+|---|---|
+| `worker-group-manager` | Per-pod worker-group lifecycle, dataset download, local inference proxy, raw-record upload coordination. One per pod. |
+| `worker-<N>` | One request-issuing worker. Count controlled by `workers_per_pod`. |
+| `record-processor-<N>` | One record processor. Count defaults to `workers_per_pod / RECORD_PROCESSOR_SCALE_FACTOR`. |
+
+### Deprecated name
+
+`worker-manager` is listed on `Containers` for backwards compatibility
+with older manifests; it is **not** placed on any pod rendered by the
+current `_JobSetManifestBuilder`. Passing `--container worker-manager`
+matches nothing and emits `No matching containers found`.
+
+---
+
+## Default behaviour (no `--container`)
+
+When `--container` is omitted, `aiperf kube logs` enumerates every pod
+matching `app=aiperf,aiperf.nvidia.com/job-id=<JOB_ID>`
+and prints the logs of **every container on every pod**, in the order
+the API returns them. For a default JobSet with `worker_replicas=N` and
+`workers_per_pod=W`, this fans out to:
+
+- the 6–9 controller-pod containers (depending on which optional
+  managers are enabled and whether the event-bus proxy sidecar is
+  configured), plus
+- `N * (1 + W + record_processors_per_pod)` worker-pod containers.
+
+For large benchmarks that total quickly runs to hundreds of containers,
+so you almost always want `--container` for interactive triage and
+`-o <dir>` for a full capture.
+
+---
+
+## Follow semantics
+
+```bash
+aiperf kube logs -f --container control-plane
+```
+
+The `-f/--follow` flag streams logs over a long-lived
+`read_namespaced_pod_log(follow=True)` connection and prints lines to
+stdout as they arrive. Key properties:
+
+- **Single-target streaming.** The implementation breaks out of the
+  target loop after the first streamed container (`if follow: break`).
+  If you pass `-f` and the resolved target list has more than one
+  entry, the CLI prints a single-line warning of the form:
+
+  ```text
+  Follow mode streams one container at a time. Showing controller-0/control-plane (9 targets total). Use --container to select a specific container.
+  ```
+
+  and only the first target is followed.
+
+- **No auto-reattach.** When the underlying pod is deleted, restarted,
+  or evicted, the stream ends and the command returns. AIPerf does
+  not transparently reconnect; re-run the command.
+
+- **Lines are soft-wrapped, never broken mid-token.** A log line wider than
+  the terminal is folded by the terminal itself, so a long URL or stack frame
+  stays copy-pasteable. Piping the output preserves one line per log line.
+
+- **Tail-at-start is supported.** `-f --tail 200` begins the stream at
+  the last 200 buffered lines, then follows live.
+
+- **Ctrl+C** terminates the stream cleanly; the `finally` block
+  releases the underlying HTTP response so the connection does not
+  leak.
+
+---
+
+## Output format
+
+Output is plain UTF-8 text, one line per log record. Each target is
+introduced by `print_header("<pod>/<container>")`, which emits a blank
+line, the `<pod>/<container>` title, and a box-drawing rule as wide as
+the title. Because the header goes through the `aiperf.kube` Rich
+logger, those three lines also carry the logger's timestamp and level
+columns; the log lines themselves are written straight to the Rich
+console and carry no prefix:
+
+```text
+20:14:07 INFO
+20:14:07 INFO     controller-0/control-plane
+20:14:07 INFO     ──────────────────────────
+<log line 1>
+<log line 2>
+...
+```
+
+Log lines are printed with highlighting and markup disabled, so nothing
+in a log line is reinterpreted as Rich markup. Bytes that cannot be
+decoded as UTF-8 are replaced (`errors="replace"`) so a single corrupt
+line never aborts the stream.
+
+---
+
+## Bulk dump to disk
+
+```bash
+aiperf kube logs <JOB_ID> -o ./triage-2026-04-22
+```
+
+With `-o <DIR>`:
+
+- The CLI creates `<DIR>/logs/` only once the label selector has matched
+  at least one pod. Nothing is created when it matches none.
+- For every pod matching the job label, it shells out to
+  `kubectl logs -n <NAMESPACE> <POD_NAME> --all-containers=true --prefix`
+  (forwarding `--kubeconfig` / `--context` when set) and writes the
+  stdout to `<DIR>/logs/<POD_NAME>.log`.
+- The closing line reports what actually reached disk:
+
+  ```text
+  Saved logs for 7 of 8 pod(s) to ./triage-2026-04-22/logs/
+  ```
+
+  A pod that produced no file emits its own warning first, carrying the
+  `kubectl logs` exit code and stderr — for example
+  `Could not save logs -- worker-0-0: kubectl logs exited 1: container has not
+  started`. When no pod produced a file at all, the closing line is a warning
+  (`No logs written to ...`), never a success.
+
+Notes on the bulk dump path specifically:
+
+- It writes **one file per pod**, not per container. Because
+  `--all-containers --prefix` is always passed, every container on the
+  pod is captured into that single file, with each line prefixed
+  `[pod/<pod>/<container>]` so you can split them apart afterwards.
+- It calls the local `kubectl` binary via `run_command`, so `kubectl`
+  must be on `PATH` and able to reach the cluster with the same
+  credentials the rest of the `aiperf kube` CLI uses.
+- `--follow`, `--container`, and `--tail` are **ignored** in
+  `--output` mode; the dump always captures the full buffered log of
+  each pod.
+
+---
+
+## Exit codes
+
+`logs` follows the [target-addressing exit-code
+convention](./workflow.md#exit-code-convention-for-target-addressing-commands):
+it narrates what it found rather than gating on it, with one exception — a
+target that cannot be addressed at all is an error.
+
+| Scenario | Exit code |
+|---|---|
+| Logs printed or written | `0` |
+| Pods matched but a container produced no output | `0` |
+| Job exists, but its pods have been garbage-collected | `0` |
+| `--container` matched no container on any pod | `0` |
+| No AIPerfJob, AIPerfSweep or JobSet with that name exists | `1` |
+| No `JOB_ID` given and no last-benchmark record on disk | `1` |
+| Any of the above two, with `--ignore-not-found` | `0` |
+
+This makes `aiperf kube logs <ID> >/dev/null` usable as a CI existence check,
+while a completed job whose pods have aged out still succeeds.
+
+---
+
+## Troubleshooting
+
+### `No pods found for <JOB_ID> in namespace <NS>`
+
+The job label selector built by `job_selector` in
+`src/aiperf/kubernetes/client_selectors.py`
+(`app=aiperf,aiperf.nvidia.com/job-id=<JOB_ID>`) matched nothing, but the
+benchmark itself still exists, so the command exits `0`. Almost always the
+JobSet has been garbage-collected by TTL: once the pods are gone, their logs
+are gone from the API server too. Check the CR phase with
+`aiperf kube list --watch`, and pull the run's captured output with
+`aiperf kube results` instead.
+
+### `No AIPerf job found with ID: <JOB_ID>`
+
+Nothing named `<JOB_ID>` exists in the resolved namespace — no AIPerfJob, no
+AIPerfSweep, and no bare JobSet — so the command exits `1`. Usually one of:
+
+- The job ID is wrong (typo, stale cache). Run `aiperf kube list` to
+  see live jobs.
+- The CR was deleted (`aiperf kube delete`, or namespace teardown).
+- `--namespace` points at the wrong namespace. Without it, the namespace
+  comes from the cached last benchmark or your kubeconfig context.
+
+### `No matching containers found`
+
+Pods exist for the job but none of them have a container named
+`--container <NAME>`. Re-check the spelling against the
+[container catalog](#container-catalog). Common mistakes:
+
+- `worker` (not a real container name — workers are indexed:
+  `worker-0`, `worker-1`, ...).
+- `worker-manager` (deprecated compat name, not present on any pod).
+- `record-processor` without an index.
+
+### `Error getting logs: (400)` or `(404)`
+
+Raised by `kubernetes_asyncio` when the API server rejects the pod-log
+request. Typical causes:
+
+- The container has not started yet (status `ContainerCreating`,
+  `PodInitializing`, or stuck on image pull). Use
+  `aiperf kube debug <JOB_ID>` to see pod phases and events.
+- The pod was deleted between the list and the read call (race
+  between `follow` reconnects and TTL cleanup).
+- The container terminated and its log buffer was rotated out of the
+  kubelet cache — try `--previous`-style recovery via `kubectl logs
+  --previous` against the pod name directly.
+
+### RBAC denials
+
+Log reads require `pods/log` access in the target namespace. If the
+CLI prints `Error getting logs: (403)`, confirm your kubeconfig user
+or ServiceAccount has the verb; see
+[rbac-security.md](./rbac-security.md) for the roles the operator
+itself uses and a minimal user-side role for log access.
+
+### Empty output
+
+A container can legitimately produce zero log lines — for example, a
+short-lived worker that failed its startup probe before any handler
+ran. In follow mode the stream simply stays silent until the container
+writes or exits; in buffered mode the CLI prints a single empty line.
+Cross-check with `aiperf kube debug` and with container status
+(`Waiting` reason / exit code) to rule out a crashed pod versus a
+quiet one.

+# Memory Estimator
+
+AIPerf ships a static memory estimator that predicts the peak and steady-state
+RSS of every pod in a Kubernetes deployment from the benchmark configuration.
+It is an **advisory** report: `aiperf kube generate`, `aiperf kube profile`, and
+the operator preflight all run it and surface its output, but none of them
+rewrite the pod's `resources` block from it. Actual requests/limits come from
+the `AIPERF_K8S_*` resource settings in `src/aiperf/kubernetes/environment.py`.
+
+If your `records-manager` OOMs at 500k concurrency, if workers get killed during
+ramp, or if you need to justify a resource bump — read this page first.
+
+---
+
+## Purpose
+
+The estimator answers three related questions:
+
+1. **Will this workload fit in the current memory limits?** Each `PodEstimate`
+   carries both the projected peak RSS and the configured K8s limit; the
+   `headroom_pct` / `at_risk` properties flag OOM risk before a job is
+   submitted.
+2. **What limits should I set?** `recommended_request_mib` (steady-state × 1.2)
+   and `recommended_limit_mib` (peak × 1.3) come straight off the estimate.
+3. **Where is the memory actually going?** Per-component breakdowns identify
+   whether `RecordsManager` growable arrays, `RecordProcessor` tokenizer caches,
+   or in-flight `Worker` records dominate — so tuning targets the right knob.
+
+The model is static: formulas are derived from code inspection, and the
+constants come from two different kinds of calibration (see the provenance
+notes on each constant in
+`src/aiperf/kubernetes/_memory_estimator/constants.py`). No runtime profiling is
+required at estimate time.
+
+- **Aggregate MiB baselines** — `_PYTHON_SUBPROCESS_BASE_MIB`,
+  `_SERVICE_BASE_MIB`, `_TOKENIZER_CACHE_MIB`, and the margin multipliers were
+  measured against real-cluster `container_memory_working_set_bytes` during the
+  2026-04-30 ISL/OSL sweep. Re-derive them only from a new cluster sweep.
+- **Per-object byte constants** — `_REQUEST_RECORD_BASE_BYTES`,
+  `_TURN_BASE_BYTES`, and the SSE / `TextResponse` terms are measured
+  in-process against the real model classes, as *amortized marginal* heap bytes
+  per instance via `tracemalloc` snapshot diffs over 1000–3000 live instances
+  after a warmup pass. Amortizing is required: the one-off cost of shared
+  field-name strings and Pydantic validator objects is paid by the first
+  instance and must not be charged to the marginal one. `sys.getsizeof` is not
+  usable — it sees only the top-level object and misses `__dict__` /
+  `__pydantic_extra__` and every referenced string.
+
+`TestPerRequestBytesAgainstMeasuredHeap` in
+`tests/unit/kubernetes/test_memory_estimator.py` re-runs that measurement on
+every test run and fails if `_per_request_bytes` drifts off the conservative
+side of it, so the per-object constants are reproducible without any external
+script.
+
+**Consumers of estimator output:**
+
+- `aiperf kube generate` — prints the full estimate to **stderr** (so stdout
+  stays a clean `kubectl apply -f -` stream) after emitting the manifests.
+- `aiperf kube profile` — prints the full estimate and warnings to **stderr**
+  before submitting the job.
+- Operator preflight (`src/aiperf/operator/preflight/_resources.py`) — runs the
+  estimator as the `Memory Estimation` check. If `estimate.warnings` is
+  non-empty the check returns `WARN` with `estimate.recommendations` as hints;
+  it does **not** fail or reject the job.
+
+---
+
+## Inputs
+
+All inputs are captured in `MemoryEstimationParams`
+(`src/aiperf/kubernetes/_memory_estimator/params.py`). They fall into four
+groups:
+
+### Topology
+
+| Field | Meaning |
+|---|---|
+| `total_workers` | Total worker processes across all pods. |
+| `workers_per_pod` | Worker processes per worker pod. |
+| `num_worker_pods` | Worker pod replica count (`ceil(total_workers / workers_per_pod)`). |
+| `record_processors_per_pod` | Record processors per worker pod. `benchmark.runtime.record_processors_per_pod` when set, otherwise `max(1, workers_per_pod // RECORD_PROCESSOR_SCALE_FACTOR)`. |
+
+`_derive_topology` reads the same config fields, in the same precedence order,
+that `spec_converter.apply_worker_config` uses to lay out the JobSet, so the
+estimate always describes the pods that are actually created. The operator calls
+`apply_worker_config` before preflight, which normalizes `workers_per_pod` and
+`record_processors_per_pod` onto the config first — so the estimate also picks up
+the cluster-wide `runtime.record_processors` total (divided across pods) and the
+single-pod collapse that a worker count not divisible by `workers_per_pod`
+triggers.
+
+The `aiperf kube generate` and `aiperf kube profile --dry-run` banners print
+their estimate from the *pre-normalization* config. An explicit
+`recordProcessorsPerPod` or `workersPerPod` is honored there, but a bare
+`runtime.record_processors` total, and the non-divisible single-pod collapse, are
+not yet resolved at that point and so are not reflected in the printed numbers.
+
+### Load profile
+
+| Field | Meaning |
+|---|---|
+| `max_concurrency` | Peak in-flight request concurrency across all workers. |
+| `total_requests` | Total requests for the entire benchmark (sum across phases). |
+| `total_benchmark_duration_s` | Total benchmark wall-clock seconds. |
+
+### Dataset shape
+
+| Field | Meaning |
+|---|---|
+| `dataset_count` | Number of conversations pre-synthesized. |
+| `avg_isl_tokens` | Weighted-mean input sequence length in tokens. |
+| `avg_osl_tokens` | Weighted-mean output sequence length in tokens. |
+| `max_turns` | Maximum conversation turns (1 for single-turn). |
+| `streaming` | SSE vs. buffered-text responses (changes per-chunk accounting). |
+| `list_metric_backend` | `ragged` keeps every inter-chunk-latency value; `tdigest` uses one bounded sketch. Derived from `AIPERF_METRICS_LIST_BACKEND`. |
+
+### Observability
+
+| Field | Meaning |
+|---|---|
+| `num_gpus`, `gpu_sample_interval_s`, `num_gpu_metrics` | DCGM sampling shape. |
+| `num_server_metrics_endpoints`, `server_metrics_scrape_interval_s` | Prometheus scrape shape. |
+| `est_unique_metric_series`, `est_histogram_metrics`, `est_histogram_buckets` | Per-endpoint series cardinality. |
+| `num_models`, `num_standard_metrics`, `export_http_trace` | Per-RP tokenizer count, per-record metrics, trace export flag. |
+
+`MemoryEstimationParams.from_config(config, total_workers, workers_per_pod,
+connections_per_worker)` is the normal entry point: it derives all of the above
+from an `AIPerfConfig` plus three deployment parameters.
+
+---
+
+## Per-component model
+
+Every per-process estimate returns a `ComponentEstimate` (see
+`src/aiperf/kubernetes/_memory_estimator/estimates.py`) with four numeric
+fields — `base_mib`, `variable_mib`, `peak_mib`, and a derived
+`steady_state_mib = base_mib + variable_mib`.
+
+Two universal baselines ride along on every process:
+
+- `_PYTHON_SUBPROCESS_BASE_MIB = 150` — interpreter + core libs + GC + every
+  module an AIPerf service loads (numpy, pandas, msgspec, pydantic, orjson,
+  aiohttp, ZMQ, asyncio). Calibrated from a real-cluster ISL/OSL sweep
+  (2026-04-30) to a ~150 MiB common baseline per container.
+- `_PYTHON_CHILD_SUBPROCESS_BASE_MIB = 150` — Worker/RP subprocesses are modeled
+  the same as the parent. Copy-on-write does not materially shrink the measured
+  working set (`container_memory_working_set_bytes` is per-container, and each
+  process's heap diverges quickly once it allocates per-task state).
+
+Each service adds a per-service overhead from `_SERVICE_BASE_MIB` (e.g.
+`records_manager: 40`, `dataset_manager: 30`, `worker: 12`,
+`record_processor: 10`).
+
+### RecordsManager
+
+Accumulates one metric record per request for the lifetime of the benchmark.
+The backing `ColumnStore` includes scalar metric columns, timestamp and
+metadata columns, categorical intern tables, and (for streaming runs) the
+list-valued `inter_chunk_latency` (ICL) metric. ICL is usually the dominant
+term when the default `ragged` backend retains every chunk gap.
+
+Source: `_estimate_records_manager`, `components.py`.
+
+For $N$ requests, $M$ standard metrics, dataset cardinality $D$, and average
+output length $O$:
+
+$$C = \max(1024, \text{ceil\_pow2}(N))$$
+$$\text{columns} = C \times \left((M - 1 + 3 + 4) \times 8\text{B} + 6 \times 4\text{B} + 2\text{B}\right) \times 1.05$$
+$$\text{intern} = (N + \min(N, D)) \times 136\text{B}$$
+
+The column counts model the `MetricsAccumulator.process_record` layout: $M-1$
+scalar metrics (the 25th standard metric is list-valued ICL), three request
+timestamps, four numeric metadata columns, six categorical `int32` code
+columns, and two boolean `uint8` columns. The categorical, boolean, and
+timestamp counts match `process_record` exactly. `process_record` passes five
+numeric metadata keys (`session_num`, `credit_issued_ns`, `request_ack_ns`,
+`cancellation_time_ns`, `turn_index`), but `ColumnStore.ingest_metadata`
+allocates a column only for non-`None` values, so the deployed column count is
+four for the default streaming workload — three without streaming (no
+`request_ack_ns`), five once any request is cancelled.
+`_COLUMN_STORE_METADATA_NUMERIC_COLUMNS = 4` therefore models the default, and
+`TestColumnStoreMetadataColumnDrift` guards it by driving records through the
+real `MetricsAccumulator.process_record` and counting the columns
+`ColumnStore` actually allocated. The intern term models a
+conservative request-unique `x_correlation_id` plus `conversation_id` values
+bounded by dataset cardinality.
+
+When streaming is enabled and `AIPERF_METRICS_LIST_BACKEND=ragged`:
+
+$$S = N \times \max(O - 1, 0)$$
+$$\text{ragged} = \max(1024, \text{ceil\_pow2}(S)) \times (8 + 4)\text{B} \times 1.05 + \max(256, \text{ceil\_pow2}(N)) \times 8\text{B}$$
+
+For $S > 0$, the first ragged term holds every ICL value as `float64` and its
+request index as `int32`; the second is the per-request `int64` offsets array.
+When $S = 0$, no ICL backend is created and the term is zero. Buffered
+responses also contribute no ICL storage. With
+`AIPERF_METRICS_LIST_BACKEND=tdigest`, the entire ICL term collapses to a
+bounded 4 KiB sketch (`_TDIGEST_LIST_BACKEND_BYTES`) regardless of request
+count, and to zero when $O \le 1$.
+
+The final variable estimate is `columns + intern + ICL + 1 MiB tracker`.
+
+Key constants:
+
+- `_FLOAT64_BYTES = 8` — numpy element width.
+- `_GROWABLE_ARRAY_OVERHEAD = 1.05` — wrapper-class overhead atop the
+  numpy-backed array (also reused by GPU-telemetry and server-metrics
+  arrays). The doubling-allocator waste is now captured separately
+  by `ceil_pow2(N)` in the capacity term, so this multiplier only covers the
+  ~0–2% wrapper overhead (dict of metric names, bucket tuple, sum tracker).
+- `_DEFAULT_NUM_STANDARD_METRICS = 25` — scalar metrics plus the one
+  list-valued ICL metric.
+- `_CATEGORICAL_INTERN_BYTES_PER_REQUEST = 136` — calibrated
+  high-cardinality string, dictionary slot, and integer-code footprint.
+- `ceil_pow2` rounds capacity up to the next power of two (the doubling
+  allocator's actual footprint, not the logical request count).
+
+**Peak** applies a 10% finalization overhead on top of variable. Tracker
+overhead (`WorkerProcessingStats` per worker) is a flat ~1 MiB.
+
+**Warning:** if `variable_mib > 500` the estimator flags the result. For a
+streaming ragged run, the warning also identifies
+`AIPERF_METRICS_LIST_BACKEND=tdigest` as the bounded-memory alternative and
+notes that its ICL percentiles are approximate.
+
+**Scales with:** `total_requests` (linearly rounded up to a power of two) and
+`num_standard_metrics`; with ragged streaming, it also scales with
+`total_requests × (avg_osl_tokens - 1)`.
+
+### DatasetManager
+
+Two memory regimes. During generation the full dataset is materialized as
+Pydantic `Conversation` objects; at steady state only the mmap index survives.
+
+Source: `_estimate_dataset_manager`, `components.py`.
+
+$$\text{bytes\_per\_turn} = 1500 + (\text{ISL} + \text{OSL}) \times 16$$
+$$\text{peak} = \text{base} + \text{dataset\_count} \times \text{max\_turns} \times \text{bytes\_per\_turn}$$
+$$\text{steady} = \text{base} + \text{dataset\_count} \times 16\text{B}$$
+
+Key constants:
+
+- `16 bytes/token` — effective token cost after Pydantic model wrappers
+  (~1 KiB per `Turn`), Python string headers, and the ~3x multiplier measured
+  against ISL=100K OSL=73K with 100 entries (~297 MiB PSS).
+- `_MMAP_INDEX_ENTRY_BYTES = 16` — per-conversation index entry at steady
+  state.
+
+**Scales with:** `dataset_count`, `max_turns`, `avg_isl + avg_osl`. Generation
+peak dominates; steady state is negligible.
+
+### Worker
+
+One process per worker. Memory = connection pool + in-flight request records
++ session cache (multi-turn only).
+
+Source: `_estimate_worker`, `components.py`. Shares the
+`_per_request_bytes(avg_isl, avg_osl, *, streaming)` helper with
+RecordProcessor so the two stay consistent.
+
+Per in-flight request:
+
+$$\text{per\_request} = \underbrace{3600}_{\text{record base}} + \underbrace{(2240 + \text{ISL} \times 4)}_{\text{turn}} + \text{response}$$
+
+Response depends on streaming mode:
+
+$$\text{response}_{\text{SSE}} = 136 + \text{OSL} \times 420 \qquad \text{response}_{\text{text}} = 152 + \text{OSL} \times 4$$
+
+Pod-level:
+
+$$\text{variable} = \text{pool} + \text{concurrency\_per\_worker} \times \text{per\_request} + \text{session\_cache}$$
+
+Key constants (`constants.py`):
+
+- `_REQUEST_RECORD_BASE_BYTES = 3600` — the Pydantic `RequestRecord` shell plus
+  the `RecordContext` it carries, with empty turns/responses lists. Both are
+  counted here because `_per_request_bytes` has no separate context term.
+  Measured 1125 B bare record + 1896 B `RecordContext`, 3596 B for the
+  populated pair.
+- `_TURN_BASE_BYTES = 2240`, `_TURN_BYTES_PER_TOKEN = 4` — `Turn` + `Text` with
+  an empty content string measured 2235 B (`Turn` alone 1576 B, `Text` alone
+  592 B); the prompt text adds a measured 4.01 B/token.
+- `_SSE_MESSAGE_BASE_BYTES = 136`, `_SSE_BYTES_PER_CHUNK = 420` — SSE per-token
+  cost is ~105x buffered text (420 B/chunk vs 4 B/token). The transport appends
+  one whole `SSEMessage` per wire chunk to `RequestRecord.responses`, so the
+  marginal cost is a message plus its packets list, its `SSEField`, and the JSON
+  string — not a bare `SSEField`. Measured 418.7 B/chunk against the
+  OpenAI-compatible chunk envelope this repo's mock server emits; a minimal
+  `{"c":"<n>"}` envelope measures 286 B/chunk, so the per-chunk cost is
+  dominated by the provider's envelope rather than by the token.
+- `_TEXT_RESPONSE_BASE_BYTES = 152`, `_TEXT_RESPONSE_BYTES_PER_TOKEN = 4` — the
+  `TextResponse` `@dataclass(slots=True)` shell measured 86 B, so the base errs
+  high by a small and deliberate margin; the body adds a measured 4.00 B/token.
+- `_BYTES_PER_CONNECTION = 1024` — aiohttp per-connection kernel + userspace
+  buffers.
+
+`RequestRecord` and `Turn` are Pydantic `AIPerfBaseModel` subclasses
+(`extra="allow"`, so each instance carries `__dict__` + `__pydantic_extra__` +
+`__pydantic_fields_set__`); `TextResponse`, `SSEMessage`, and `SSEField` are
+`@dataclass(slots=True)` and much cheaper. The record and turn constants were
+originally derived assuming `msgspec.Struct` layout, which left them 2.2–5.4x
+low, and `_SSE_BYTES_PER_CHUNK` was fitted against a one-message-many-packets
+shape the transport never builds. Both were corrected on 2026-08-24; the
+prediction now lands at 1.01–1.07x of measured across streaming and buffered
+shapes at ISL=512/OSL=128 and ISL=1024/OSL=1024.
+
+Session cache activates when `max_turns > 1`: prior-turn prompts stay resident
+for the session duration.
+
+**Scales with:** `max_concurrency / total_workers`, `avg_osl`, streaming mode,
+`max_turns`, `connections_per_worker`.
+
+### RecordProcessor
+
+One process per RP; `record_processors_per_pod` copies live in each worker
+pod. Memory = tokenizer cache + in-flight records + raw-batch and
+export-batch buffers.
+
+Source: `_estimate_record_processor`, `components.py`.
+
+$$\text{variable} = \underbrace{\text{num\_models} \times 150}_{\text{tokenizer}} + \underbrace{\text{rp\_queue\_depth} \times \text{per\_record}}_{\text{inflight}} + \text{raw\_buf} + \text{export\_buf}$$
+
+Key constants:
+
+- `_TOKENIZER_CACHE_MIB = 150` — per distinct model (GPT-2 ~73 MiB, Llama-3
+  ~50–100 MiB, large SentencePiece models ~150 MiB).
+- `_RAW_BATCH_SIZE = 10`, `_EXPORT_BATCH_SIZE = 100`,
+  `_EXPORT_BYTES_PER_RECORD = 1100` (module-local in `components.py`).
+
+**Queue-depth amplification at high token counts** — the
+`_rp_queue_depth(conc_per_rp, isl, osl)` helper in `estimator.py` models the
+fact that tokenization becomes the bottleneck for ISL+OSL > 10K. Records pile
+up in the RP's unbounded ZMQ pull queue as fully deserialized Python objects:
+
+$$\text{rp\_queue\_depth} = \begin{cases} \text{conc\_per\_rp} \times \min\!\left(\tfrac{\text{ISL}+\text{OSL}}{10000}, 10\right) & \text{if ISL}+\text{OSL} > 10{,}000 \\ \text{conc\_per\_rp} & \text{otherwise} \end{cases}$$
+
+Calibrated against PSS: at ISL+OSL=173K the queue reaches ~150 records per RP
+(10x base). This is the mechanism by which large-token benchmarks OOM worker
+pods even at moderate concurrency.
+
+**Warnings:** triggers on `inflight_mib > 50` (high token pressure) or
+`tokenizer_mib > 450` (too many models loaded per RP).
+
+**Scales with:** `num_models`, `concurrency_per_rp` (amplified by token
+count), streaming mode, `avg_isl + avg_osl`.
+
+### ServerMetrics
+
+Prometheus scrape history, one time series per metric per endpoint, held in
+growable arrays identical in shape to RecordsManager.
+
+Source: `_estimate_server_metrics`, `components.py`.
+
+$$\text{scalar\_bytes} = \text{scalar\_count} \times \text{ceil\_pow2}(\text{n\_scrapes}) \times 16\text{B}$$
+$$\text{hist\_bytes} = \text{hist\_count} \times \text{ceil\_pow2}(\text{n\_scrapes}) \times (24 + \text{buckets} \times 8)\text{B}$$
+$$\text{variable} = \text{num\_endpoints} \times (\text{scalar} + \text{hist} + \text{fetch}) \times 1.05$$
+
+Key constants (`constants.py`):
+
+- `_DEFAULT_SCRAPE_INTERVAL_S = 5.0`
+- `_DEFAULT_UNIQUE_METRIC_SERIES = 200`,
+  `_DEFAULT_HISTOGRAM_METRICS = 20`,
+  `_DEFAULT_HISTOGRAM_BUCKETS = 10`.
+
+Returns zero if `num_endpoints == 0` (server metrics disabled).
+
+**Scales with:** `num_endpoints`, `duration_s / scrape_interval_s`,
+`unique_series`, `histogram_buckets`.
+
+### GPUTelemetry
+
+DCGM samples held as columnar numpy arrays, one per metric per GPU.
+
+Source: `_estimate_gpu_telemetry`, `components.py`.
+
+$$\text{per\_gpu\_bytes} = \text{ceil\_pow2}(\text{n\_samples}) \times 8 + \text{num\_metrics} \times \text{ceil\_pow2}(\text{n\_samples}) \times 8$$
+$$\text{variable} = \text{num\_gpus} \times \text{per\_gpu\_bytes} \times 1.05$$
+
+Key constants:
+
+- `_DEFAULT_GPU_METRICS = 12` (DCGM default set).
+- `gpu_sample_interval_s = 1.0` (default in `params.py`).
+- `_GROWABLE_ARRAY_OVERHEAD = 1.05` — applied as a single multiplier to the
+  total GPU telemetry footprint (same constant as RecordsManager). The
+  `formula` string this component reports interpolates the constant, so the
+  display and the arithmetic cannot diverge.
+
+Returns zero when `num_gpus == 0` — no DCGM URLs, or GPU telemetry disabled.
+The operator omits the container entirely in that case.
+
+**Scales with:** `num_gpus`, `duration_s / sample_interval_s`,
+`num_gpu_metrics`.
+
+### Fixed-overhead services
+
+`SystemController`, `TimingManager`, `APIService`, `ResultsSidecar` (on the
+controller pod) and `WorkerGroupManager` (on each worker pod) all use
+`_estimate_fixed_service`: a flat `_SERVICE_BASE_MIB[name] +
+_PYTHON_SUBPROCESS_BASE_MIB` with `variable_mib = 0`. These do not scale with
+workload.
+
+Plus 3 ZMQ proxies at 5 MiB each (`_ZMQ_PROXY_MIB = 5`,
+`_NUM_ZMQ_PROXIES = 3`) on the controller pod.
+
+---
+
+## Output schema
+
+`estimate_memory(config, ...)` returns a `ClusterMemoryEstimate`:
+
+```
+ClusterMemoryEstimate
+├── params: MemoryEstimationParams        # echoed inputs
+├── controller: PodEstimate
+│   ├── components: list[ComponentEstimate]   # per-service breakdown
+│   ├── current_limit_mib: float              # configured K8s limit
+│   ├── replicas: int

+└── recommendations: list[str]                # actionable tuning suggestions
+```
+
+The `replicas` field on `worker_pod` is the number of worker pods; use
+`worker_pod.total_steady_state_mib * worker_pod.replicas` for the cluster-wide
+worker footprint.
+
+Every `ComponentEstimate` also carries a `formula` string and a
+`dominant_factor` string that spell out how its number was derived. Neither is
+rendered by `format_estimate()` in `formatting.py` — the report that
+`aiperf kube profile` prints shows the topology header, per-pod steady/peak
+tables with a `[!]` marker on warned components, the cluster total, and then
+the `warnings` and `recommendations` lists. Read `formula` programmatically if
+you need the breakdown.
+
+---
+
+## OOM risk warnings
+
+The estimator attaches warnings at two layers.
+
+### Per-component (attached to `ComponentEstimate.warning`)
+
+| Component | Trigger | Message pattern |
+|---|---|---|
+| RecordsManager | `variable_mib > 500` | `"variable memory is X MiB ... consider reducing request count"` |
+| RecordProcessor | `inflight_mib > 50` | `"in-flight records use X MiB ... driven by <mode> ISL=... OSL=... at concurrency N"` |
+| RecordProcessor | `tokenizer_mib > 450` | `"tokenizer cache is X MiB ... consider reducing model count"` |
+
+`ComponentEstimate.warning` holds at most one string, so the two RecordProcessor
+triggers are mutually exclusive: when both conditions hold, the in-flight
+message wins and the tokenizer message is suppressed.
+
+### Per-cluster (appended to `ClusterMemoryEstimate.warnings`)
+
+| Warning | Trigger (constant) | Meaning |
+|---|---|---|
+| Controller pod at risk | `headroom_pct < 15%` (`_HEADROOM_WARNING_PCT`) | Peak is within 15% of limit; OOM likely. |
+| RecordsManager dominates controller | RM > 50% of controller limit (`_RECORDS_MANAGER_WARN_PCT`) | Request count is the single largest driver. |
+| Worker pod at risk | `headroom_pct < 15%` | Per-pod peak too close to limit. |
+| High request volume | `total_requests > 500_000` | Expect significant metric array storage. |
+| Many models per RP | `num_models * 150 > 450 MiB` | Tokenizer cache will dominate each RP. |
+| HTTP trace at scale | `export_http_trace and total_requests > 10_000` | Per-chunk trace data accumulates unboundedly. |
+| Multi-turn with heavy concurrency | `max_turns > 1 and sessions_per_worker > 100` | Session cache may grow significantly. |
+
+`recommendations` are built by `_build_recommendations(est)` — it prints the
+specific `recommended_limit_mib` values to bump to, or confirms that current
+limits have adequate headroom.
+
+---
+
+## How to run it
+
+### Programmatic
+
+```python
+import yaml
+
+from aiperf.config.config import AIPerfConfig
+from aiperf.kubernetes.memory_estimator import estimate_memory, format_estimate
+
+with open("bench.yaml") as fh:
+    config = AIPerfConfig.model_validate(yaml.safe_load(fh))
+
+est = estimate_memory(
+    config,
+    total_workers=10,
+    workers_per_pod=None,      # None = config.benchmark.runtime.workers_per_pod,
+                               # else AIPERF_WORKER_DEFAULT_WORKERS_PER_POD
+    connections_per_worker=200,
+)
+print(format_estimate(est))
+
+if est.controller.at_risk:
+    raise SystemExit(
+        f"Controller would OOM: need {est.controller.recommended_limit_mib} MiB, "
+        f"have {est.controller.current_limit_mib:.0f} MiB"
+    )
+```
+
+### Via CLI
+
+`aiperf kube profile` derives `MemoryEstimationParams.from_config(...)` from
+the rendered config and prints the full report to **stderr** — including
+per-pod tables, warnings, and recommendations — before any cluster resources
+are created.
+
+`aiperf kube generate` runs the same estimate and prints it to **stderr**
+after writing the manifests to stdout. The rendered manifests take their
+`resources.requests` / `resources.limits` from the `AIPERF_K8S_*` resource
+settings, not from `recommended_request_mib` / `recommended_limit_mib` — read
+the report, then set the env vars yourself if it says you need to.
+
+The operator preflight step (`src/aiperf/operator/preflight/_resources.py`)
+runs the estimator once more as the `Memory Estimation` check. Any estimator
+warning downgrades that check to `WARN` and attaches `recommendations` as
+hints; it never blocks admission.
+
+---
+
+## Tuning recipes
+
+### "My records-manager OOMs at 500k concurrency"
+
+1. Run `aiperf kube profile` and look at the `RecordsManager` row in the
+   Controller Pod table.
+2. If `RecordsManager uses N% of controller limit` appears in warnings, read
+   that component's `formula` string (not printed by the report — see
+   [Output schema](#output-schema)): it separates fixed `ColumnStore` columns,
+   categorical intern entries, and ICL storage. For streaming runs, ragged ICL
+   scales as `requests × (OSL - 1)` and can dominate by gigabytes.
+3. If exact ICL percentiles and ICL-aware sweep curves are not required, set
+   `AIPERF_METRICS_LIST_BACKEND=tdigest`. This bounds ICL aggregation to about
+   4 KiB while retaining exact count/sum/min/max/average/std and approximate
+   percentiles. Otherwise, provision for the ragged estimate.
+4. Bump `AIPERF_K8S_RECORDS_MANAGER_MEMORY` (and `AIPERF_K8S_RECORDS_MANAGER_CPU`)
+   on the operator. `current_limit_mib` for the controller pod is the **sum** of
+   the memory limits across `CONTROLLER_RESOURCE_KEYS` (see
+   `aiperf.kubernetes.environment`), so raise that sum until it clears the
+   pod-level `recommended_limit_mib`.
+
+### "Workers OOM mid-ramp on a large-token workload"
+
+Check the RecordProcessor warning first. If `in-flight records use X MiB` fires
+with `ISL+OSL > 10_000`, you have hit the tokenization-queue-depth
+amplification — at ISL+OSL=173K the queue reaches 10x `conc_per_rp`. Options:
+
+- Raise `--total-workers`. In the estimator's model `conc_per_rp` reduces to
+  `max_concurrency / total_workers` at the default
+  `AIPERF_K8S_RECORD_PROCESSOR_SCALE_FACTOR=1` (one RP per worker), because
+  `workers_per_pod` scales the pod's concurrency and its RP count by the same
+  factor — increasing `workers_per_pod` alone does not move the number.
+- Bump the worker pod's memory limit (`AIPERF_K8S_WORKER_POD_MEMORY`) to the
+  estimator's `recommended_limit_mib`.
+- Lower `benchmark.runtime.record_processors_per_pod`. This packs fewer RPs into
+  each pod, and the estimate follows it: at the default scale factor, dropping
+  from one RP per worker to a single RP on a 4-worker pod removes roughly 975 MiB
+  of peak per-pod RP memory. It raises `conc_per_rp` in exchange, so re-read the
+  RecordProcessor warning afterwards.
+
+### "Tokenizer cache dominates each RP"
+
+Triggered by `num_models * 150 MiB > 450 MiB`. Either split models across
+separate AIPerfJob CRs (one model per benchmark) or accept the higher
+worker-pod memory limit — there is no per-process cache deduplication.
+
+### "The estimator disagrees with measured RSS"
+
+Constants are calibrated but static. Which class of constant is wrong decides
+how to fix it:
+
+- **A per-object byte constant.** Re-measure it. Extend
+  `TestPerRequestBytesAgainstMeasuredHeap` in
+  `tests/unit/kubernetes/test_memory_estimator.py` with your shape, read the
+  measured value out of the assertion message, and update the constant. The
+  test enforces `1.0 <= predicted / measured <= 1.6`, so a prediction that
+  lands *below* measured is a bug and a prediction slightly above it is
+  correct — the output is a limit recommendation. The per-chunk SSE cost is
+  dominated by the provider's chunk envelope, so a server with unusually large
+  chunks (per-chunk `usage`, `logprobs`) will legitimately exceed the model.
+- **An aggregate MiB baseline.** These come from a real-cluster
+  `container_memory_working_set_bytes` sweep and cannot be re-derived
+  in-process. Update them only from a new cluster measurement.
+
+Record the provenance in the constant's comment the way the existing ones do —
+state the method, the date, and the shape measured. Do not edit the formulas
+ad-hoc.

+# Monitoring and Troubleshooting
+
+AIPerf provides several tools for monitoring running benchmarks, diagnosing problems, and retrieving logs. This guide covers how to use each one.
+
+---
+
+## Attaching to a Benchmark
+
+The `attach` command connects to a running benchmark via port-forward and streams live progress updates via WebSocket:
+
+```bash
+aiperf kube attach
+```
+
+`aiperf kube profile` follows the run automatically after deploying unless you
+pass `--detach`, but in operator mode (the default) it polls the AIPerfJob CR
+rather than port-forwarding. Use `attach` to get the WebSocket progress stream,
+to reconnect after detaching, or to watch from a different terminal.
+
+Attach to a specific job:
+
+```bash
+aiperf kube attach my-benchmark
+```
+
+Press **Ctrl+C** to detach. This only closes your local stream; the benchmark
+keeps running in the cluster. To stop the benchmark, run `aiperf kube cancel
+<job>`, which patches `spec.cancel: true` so the operator tears down the JobSet
+and stamps `status.phase=Cancelled`.
+
+---
+
+## Listing Jobs
+
+See all benchmark jobs and their status:
+
+```bash
+aiperf kube list
+```
+
+```
+NAME               NAMESPACE          OWNER  PHASE      WORKERS  PROGRESS  THROUGHPUT  LATENCY   AGE

+
+`WORKERS` is `ready/total`, `THROUGHPUT` is requests per second, and `LATENCY`
+is the p99 request latency. A dash means the CR has not published that value.
+`OWNER` names the scoped operator holding that namespace's claim; `-` means the
+cluster-wide operator reconciles it and `?` means the claim was unreadable.
+
+### Filter by Status

+aiperf kube list --wide
+```
+
+### Live Refresh
+
+Watch the list with automatic updates:
+
+```bash
+aiperf kube list --watch

+
+## Reading Logs
+
+Get logs from all pods associated with a benchmark:
+
+```bash
+aiperf kube logs
+```
+
+### Specific Job
+
+```bash
+aiperf kube logs my-benchmark
+```
+
+### Specific Container
+
+The controller pod runs `control-plane` (the SystemController) alongside per-service containers (`dataset-manager`, `timing-manager`, `records-manager`, `api`, `event-bus-proxy`, `results-sidecar`, and optionally `gpu-telemetry-manager` / `server-metrics-manager`). Worker pods run `worker-group-manager`. To see logs from a specific container:
+
+```bash
+aiperf kube logs --container control-plane
+```
+
+### Follow Logs in Real-Time
+
+```bash
+aiperf kube logs -f
+```
+
+### Last N Lines
+
+```bash
+aiperf kube logs --tail 100
+```
+
+### Save Logs to Files
+
+Save all pod logs to a directory (one file per pod):
+
+```bash
+aiperf kube logs --output ./my-logs
+```
+
+The closing line counts what actually reached disk (`Saved logs for 7 of 8
+pod(s) to ./my-logs/logs/`), and any pod whose `kubectl logs` call failed gets
+its own warning with the exit code and stderr. When nothing was written the
+closing line is a warning, not a success.
+
+### Exit Codes in Scripts
+
+`attach` and `logs` exit `1` when the benchmark you named does not exist, so
+they work as CI existence checks. A benchmark that exists but has no pods left
+(TTL-collected) still exits `0`. Pass `--ignore-not-found` — same spelling and
+meaning as `kubectl`'s — to force exit `0` for a missing benchmark in teardown
+scripts. The other addressing commands (`cancel`, `delete`, `shutdown`, `debug`,
+`list`) always exit `0`; see the [exit-code
+convention](./workflow.md#exit-code-convention-for-target-addressing-commands).
+
+---
+
+## Debugging Failed Benchmarks
+
+The `debug` command runs a one-shot diagnostic analysis of your deployment:
+
+```bash
+aiperf kube debug -n my-benchmarks
+```
+
+It inspects:
+
+- **Pod states** -- Identifies CrashLoopBackOff, ImagePullBackOff, ErrImagePull, OOMKilled, CreateContainerConfigError, RunContainerError, and Unschedulable, each with a suggested fix
+- **Kubernetes events** -- Shows the most recent warning events (or all recent events with `--verbose`)
+- **Node resources** -- Reports CPU, memory, and GPU allocatable vs. capacity for each node
+- **Benchmark diagnostics** -- When `--job-id` targets a specific job, runs the metric detectors in `aiperf.kubernetes.benchmark_diagnosis` over `status.liveMetrics`: high error rate, high tail latency (p99 above a multiple of the average), and a stalled job (Pending too long, or Running with neither throughput nor completed requests). Thresholds are the `AIPERF_K8S_DIAGNOSIS_*` environment variables. The section is omitted when nothing tripped.
+- **Container logs** -- With `--verbose`, fetches recent logs from problem pods
+
+### Debug a Specific Job
+
+```bash
+aiperf kube debug --job-id my-benchmark
+```
+
+### Verbose Mode
+
+Includes container logs from pods with problems:
+
+```bash
+aiperf kube debug --job-id my-benchmark --verbose
+```
+
+### All Namespaces
+
+Scan every namespace that has AIPerf deployments:
+
+```bash
+aiperf kube debug --all-namespaces
+```
+
+### Sample Output
+
+```

+
+## Pre-Flight Checks
+
+Before deploying, validate that the cluster is ready:
+
+```bash
+aiperf kube preflight
+```
+
+It runs these checks in order, and stops early only if cluster connectivity
+fails:
+
+- Cluster connectivity and Kubernetes version
+- Namespace exists (AIPerf never creates it)
+- RBAC permissions in the target namespace
+- JobSet CRD installed and JobSet controller running
+- Resource quotas and node resources
+- Referenced secrets and image-pull access
+- Network policies and DNS resolution
+- Endpoint connectivity (when `--endpoint-url` is given)
+
+### With Specific Parameters
+
+```bash
+aiperf kube preflight \
+  --image nvcr.io/nvidia/aiperf:latest \
+  --endpoint-url http://my-server:8000 \
+  --workers 20 \
+  --namespace my-benchmarks
+```
+
+### JSON Output
+
+For CI/CD pipelines:
+
+```bash
+aiperf kube preflight -o json
+```
+
+Returns a structured JSON object with pass/fail/warn status for each check, suitable for automated gating.
+
+---
+
+## Retrieving Results
+
+After a benchmark completes, get the results:
+
+```bash
+aiperf kube results
+```
+
+By default this downloads the full results package from the operator's PVC storage (use `--from-pods` to pull from the benchmark pods instead). The results include:
+
+- `profile_export_aiperf.json` -- Summary metrics
+- `profile_export.jsonl` -- Per-request timing data
+- Server metrics and other exported files
+
+### From the Operator Storage
+
+Even after pods are deleted, results are stored on the operator's PVC. This is the default:
+
+```bash
+aiperf kube results my-benchmark
+```
+
+### Summary Only
+
+Download only the summary results (faster):
+
+```bash
+aiperf kube results --summary-only
+```
+
+### Direct From Pods
+
+If you want to fetch results directly from the running benchmark pods (via the controller API):
+
+```bash
+aiperf kube results --from-pods
+```
+
+The default `--all` path uses the controller API and nothing else — if that
+call fails, the download fails. The `kubectl cp` fallback applies only to
+`--summary-only`, which tries the API first and then copies from the
+`control-plane` container.
+
+### Shut Down After Download
+
+Free up cluster resources by shutting down the API service after downloading (only takes effect with `--from-pods`):
+
+```bash
+aiperf kube results --from-pods --shutdown
+```
+
+### Save to Custom Directory
+
+```bash
+aiperf kube results --output ./my-results
+```
+
+---
+
+## Common Issues and Solutions
+
+### Expired Local Kubernetes Login
+
+When an interactive `aiperf kube` command receives HTTP 401 or a recognized
+`kubectl` logged-out response, it pauses and reloads the selected kubeconfig
+until your normal credential provider works again. Complete the usual login
+(for example, your OIDC, cloud, or access-proxy login) in another terminal.
+AIPerf does not launch the provider or request credentials itself. Press
+**Ctrl+C** to stop waiting.
+
+This behavior is limited to terminals with interactive input and output.
+Operator pods, in-cluster service accounts, redirected output, and CI fail
+immediately so unattended work cannot hang. HTTP 403 is also returned
+immediately because it means the authenticated identity lacks RBAC permission,
+not that the login expired. Missing credential-provider executables, malformed
+plugins, TLS failures, and unreachable API servers remain ordinary errors.
+
+### Pods Stuck in Pending
+
+**Symptom:** `aiperf kube list` shows `Pending` and pods never start.
+
+**Diagnosis:**
+```bash
+aiperf kube debug --job-id my-benchmark
+```
+
+**Common causes:**
+- Insufficient resources (CPU, memory, GPU) -- check node capacity in the debug output
+- Missing node selectors or tolerations -- pods may be targeting nodes that don't exist
+- Kueue quota exhausted -- check your ClusterQueue capacity
+
+In operator mode, inspect the durable startup diagnosis directly:
+
+```bash
+kubectl get aiperfjob my-benchmark \
+  -o jsonpath='{.status.startupIssue}{"\n"}{.status.conditions[?(@.type=="WorkersReady")]}{"\n"}'
+```
+
+Temporary capacity shortages, pending PVC binding, Kueue admission, and unknown
+scheduler reasons remain retryable even when `timeoutSeconds: 0`. Stable image,
+container-configuration, crash-loop, node-selector, untolerated-taint, and
+volume-affinity blockers fail only after the critical startup grace period.
+Tune warning and critical thresholds with
+`AIPERF_K8S_WATCHDOG_PENDING_THRESHOLD_SECONDS` and
+`AIPERF_K8S_WATCHDOG_PENDING_CRITICAL_THRESHOLD_SECONDS` on the operator
+container.
+
+### ImagePullBackOff
+
+**Symptom:** Pods fail with `ImagePullBackOff`.
+
+**Fix:** Verify the image exists and pull secrets are configured:
+```bash
+# Check preflight
+aiperf kube preflight --image your-image:tag
+
+# Add pull secrets
+aiperf kube profile ... --image-pull-secrets my-registry-secret
+```
+
+### OOMKilled
+
+**Symptom:** Worker pods restart with `OOMKilled` status.
+
+**Fix:** Reduce concurrency per worker pod so each pod uses less memory:
+```yaml
+spec:
+  connectionsPerWorker: 50    # reduce from default 100
+```
+
+`spec.connectionsPerWorker` is immutable after creation, so changing it means
+creating a new AIPerfJob.
+
+The per-pod memory budget is resolved by the process that renders the JobSet, so
+it is set on the operator container rather than in the CR. The chart has no
+values key for it; patch the Deployment directly:
+
+```bash
+kubectl set env -n aiperf-system deploy/aiperf-operator \
+  AIPERF_K8S_WORKER_POD_MEMORY=8Gi
+```
+
+Per job, `spec.resourceMode` selects the QoS shape: `burstable` (the default)
+sets requests without limits so containers are not cgroup-OOM-killed for
+exceeding their request, `guaranteed` sets `requests == limits`, and `none`
+omits both. It is also immutable after creation.
+
+### Benchmark Timeout
+
+**Symptom:** Job transitions to `Failed` with timeout error.
+
+**Fix:** Increase or disable the timeout:
+```yaml
+spec:
+  timeoutSeconds: 3600    # 1 hour
+  # or
+  timeoutSeconds: 0       # no timeout
+```
+
+### Endpoint Unreachable
+
+**Symptom:** Operator reports endpoint health check failure.
+
+**Diagnosis:** Verify the Dynamo frontend is reachable from inside the cluster:
+```bash
+kubectl run curl-test --rm -it --image=curlimages/curl -- \
+  curl -s http://dynamo-agg-frontend.dynamo-server.svc:8000/v1/models
+```
+
+**Fix:** Ensure the Dynamo deployment is healthy (`kubectl get pods -n dynamo-server`), and the URL in your config uses the correct frontend service DNS name: `http://{deploy-name}-frontend.{namespace}.svc:8000/v1`.
+
+### Stale Namespaces
+
+The CLI-side watchdog that runs while `aiperf kube profile` follows a benchmark
+warns when it finds more than two leftover `aiperf-*` namespaces. Remove the
+finished benchmarks inside one with `aiperf kube cleanup`, or delete the
+namespace outright:
+
+```bash
+aiperf kube cleanup --namespace aiperf-bench-old --force
+kubectl delete namespace aiperf-bench-old
+```
+
+---
+
+## Web Dashboard
+
+The AIPerf operator includes a built-in web dashboard for comprehensive monitoring and analysis of your benchmarks.
+
+Access it by port-forwarding to the operator:
+
+```bash
+kubectl port-forward -n aiperf-system deploy/aiperf-operator 8081:8081
+```
+
+Then open [http://localhost:8081](http://localhost:8081) in your browser.
+
+### Dashboard Features
+
+- **Dashboard Tab** -- Overview with KPI cards, active jobs count, and throughput trends across all jobs
+- **Jobs Tab** -- Sortable table of all benchmark jobs with phase filters (Running, Completed, Failed)
+- **Job Detail Page** -- Live metrics, charts, phase progress bar, and pod status for a single job
+- **Sweeps Tab** -- Table of AIPerfSweeps with per-sweep drill-down (variation curves, Pareto, children)
+- **Leaderboard Tab** -- Rank benchmark runs by any metric (throughput, latency percentiles, etc.)
+- **Compare Tab** -- Side-by-side comparison of multiple jobs to identify performance differences
+- **History Tab** -- Time-series charts showing how metrics evolve across all your benchmark runs
+
+See [Web Dashboard](dashboard-ui.md) for the full page-by-page reference.
+
+### Quick Navigation
+
+Use **Ctrl+K** to open the command palette and quickly jump to any job or page. Search by job name or view recent benchmarks.

+
+## Operator Prometheus Metrics
+
+The kopf operator container exposes a Prometheus `/metrics` endpoint from an
+in-process daemon thread (`src/aiperf/operator/metrics.py`). The port is
+`AIPERF_METRICS_PORT` (`OperatorEnvironment.METRICS_PORT`, default **9090**; set
+to `0` to disable). This is separate from the results-server on 8081.
+
+```bash
+kubectl port-forward -n aiperf-system deploy/aiperf-operator 9090:9090
+curl http://localhost:9090/metrics
+```
+
+Exposed series:
+
+| Metric | Type | Labels | Meaning |
+|---|---|---|---|
+| `aiperf_operator_handler_duration_seconds` | Histogram | `handler` | Wall-clock duration of each instrumented kopf reconcile handler. |
+| `aiperf_operator_handler_total` | Counter | `handler`, `outcome` | Reconcile-handler invocations by outcome. |
+| `aiperf_operator_completion_claim_races_total` | Counter | — | Lost `try_claim_completion` races (concurrent ticks contending for the completion claim). |
+
+`outcome` is one of four values: `success` (returned normally), `retry` (raised
+`kopf.TemporaryError`, so kopf will re-dispatch), `fatal` (raised
+`kopf.PermanentError`, so kopf stops retrying and the CR is stuck), and `error`
+(anything else, including `CancelledError`, `KeyboardInterrupt`, and
+`SystemExit`). `retry` and `fatal` are separated so you can alert on stuck CRs
+without false positives from transient apiserver hiccups.
+
+Only kopf reconcile handlers are instrumented (via the `@track_handler("name")`
+decorator); helper functions are not.
+
+### Benchmark Metrics from the Controller Pod
+
+Separately from the operator's own reconcile metrics, each benchmark's
+controller pod serves its live benchmark metrics in Prometheus exposition
+format from the `api` container at `/metrics` on the API port (default 9090).
+The controller pod is annotated with `prometheus.io/scrape: "true"`,
+`prometheus.io/port`, and `prometheus.io/path: /metrics`, so an
+annotation-based Prometheus scrape config picks it up without extra
+configuration.
+
+Set `serviceMonitor.enabled=true` in the chart to have a Prometheus Operator
+`ServiceMonitor` scrape the Service's `metrics` port at `/metrics`. It is off by
+default, and is skipped when `operator.metrics.port` is `0` or when the
+`monitoring.coreos.com/v1` CRDs are absent. The repository ships no Grafana
+dashboards or `PrometheusRule` alerts.

+
+# Preflight Checks
+
+Preflight checks validate that a Kubernetes cluster is ready to run an AIPerf benchmark
+before any resources are created. They surface common failure modes (missing CRDs,
+insufficient RBAC, exhausted quotas, malformed manifests) as explicit, actionable
+failures instead of cryptic pod errors an hour into a run.
+
+There are two entry points:
+
+- **`aiperf kube preflight`** — ad-hoc CLI check against the target cluster. Does not
+  require an AIPerfJob CR.
+- **Operator preflight** — runs on every `AIPerfJob` creation, before the operator
+  creates the ConfigMap, JobSet, Role, or RoleBinding. On any `FAIL`, the operator
+  sets the CR to `Failed` with a `PreflightPassed=False` condition and does not create
+  resources.
+
+Both share the same `CheckResult` / `CheckStatus` / `PreflightResults` shapes
+(`src/aiperf/kubernetes/preflight.py`). The check sets differ because each has
+different inputs: the CLI knows only what the user passed on the command line; the
+operator has the full resolved deployment spec.
+
+## Tiered execution
+
+The operator runs checks in tiers. Later tiers only run if earlier tiers pass —
+no point probing node capacity if the cluster is the wrong Kubernetes version.
+See `src/aiperf/operator/preflight/_checker.py:89` (`OperatorPreflightChecker.run_all`).
+
+```mermaid
+flowchart TD
+    T1[Tier 1: Cluster compatibility<br/>K8s version, JobSet CRD]
+    T2[Tier 2: RBAC permissions]
+    T3[Tier 3+: Concurrent checks<br/>infra, resources, workload]
+    Admit[Admit: create ConfigMap and JobSet]
+    Reject[Reject: CR set to Failed<br/>PreflightPassed=False]
+
+    T1 -->|all pass| T2
+    T2 -->|pass| T3
+    T3 -->|no FAIL| Admit
+    T1 -->|any FAIL| Reject
+    T2 -->|FAIL| Reject
+    T3 -->|any FAIL| Reject
+```
+
+Tier 1 and Tier 2 are sequential and short-circuit: the first failing check aborts the
+whole run. Tier 3+ checks are fanned out with `asyncio.gather` and all results are
+collected regardless of individual failures — users see every problem in one pass
+rather than fix-and-retry whack-a-mole.
+
+The whole sequence is bounded by `AIPERF_PREFLIGHT_TIMEOUT` (default 30 s,
+`src/aiperf/operator/environment.py:367`). If the deadline fires while a
+sequential blocking check is still running, the synthetic `Preflight Timeout`
+check is `FAIL` and the operator rejects the CR. A timeout among concurrent
+advisory checks is reported as `WARN`; completed results are retained.
+
+## Operator vs. CLI invocation
+
+| Aspect | Operator (`OperatorPreflightChecker`) | CLI (`CLIPreflightChecker`) |
+|---|---|---|
+| Trigger | `kopf.on.create` for `AIPerfJob` | `aiperf kube preflight` |
+| Inputs | Fully resolved `DeploymentConfig`, `KubernetesDeployment`, `AIPerfConfig` | CLI flags only |
+| Check count | 19 | 14 |
+| On FAIL | CR → `Failed`, `kopf.PermanentError` raised | CLI exits 1, JSON output on stdout if `-o json` |
+| Source | `src/aiperf/operator/preflight/_checker.py` | `src/aiperf/kubernetes/preflight.py:CLIPreflightChecker` |
+
+## Status values
+
+Every check produces one of five statuses (`CheckStatus`,
+`src/aiperf/kubernetes/preflight.py`):
+
+| Status | When |
+|---|---|
+| `pass` | Check confirmed the cluster meets the requirement. |
+| `fail` | Check confirmed a blocking problem. Operator rejects the CR; CLI exits 1. |
+| `warn` | Potential problem or non-blocking concern (e.g. quota close to limit, tainted-node mismatch). Does not block. |
+| `skip` | Check not applicable (e.g. no nodeSelector set, no secrets referenced, Kueue not installed). |
+| `info` | Informational only — value reported, no pass/fail judgment (e.g. external endpoint URL was parsed but cannot be dialled from the CLI). |
+
+## CLI command
+
+```
+aiperf kube preflight [OPTIONS]
+```
+
+| Flag | Type | Default | Purpose |
+|---|---|---|---|
+| `-i`, `--image` | string | unset | Container image to inspect. Enables image-registry and pull-secret checks. |
+| `--image-pull-secret`, `--image-pull-secrets` | string (repeatable) | unset | Image pull secret name to verify and associate with the image check. Repeat for multiple names. |
+| `--secret`, `--secrets` | string (repeatable) | unset | Referenced Kubernetes secret name to verify. Repeat for multiple names. |
+| `-e`, `--endpoint-url` | string | unset | LLM endpoint URL to probe. Enables the endpoint-connectivity check (cluster-service lookup for `*.svc` URLs; informational for external URLs). |
+| `-w`, `--workers` | int | 1 | Planned worker pod count. Used to project CPU and memory requirements against node capacity and namespace quotas. |
+| `--node-selector` | string (JSON or repeatable `key=value`) | unset | Restricts capacity admission to nodes matching the planned pod selector. |
+| `--tolerations` | JSON object or array | unset | Tolerations the planned pods carry; allows capacity admission to include matching NoSchedule or NoExecute taints. |
+| `-o`, `--output` | `text`\|`json` | `text` | Output format. `text` prints rich-formatted progress; `json` prints only the machine-parseable `PreflightResults` dict on stdout. Log records are retargeted to stderr for the duration and quietened to `WARNING`, so stdout is safe to pipe into `jq` even when checks fail. |
+
+Composite flags inherited from `KubeManageOptions` — `-n`/`--namespace`,
+`--kubeconfig`, `--kube-context` — resolve connection and namespace identically to
+every other `aiperf kube` subcommand. When `--namespace` is omitted, preflight
+targets the namespace your kubeconfig context sets, and fails if it sets none.

+
+## Check catalog — Tier 1 (blocking, cluster compatibility)
+
+### Cluster Connectivity (CLI only)
+
+- **Validates**: `client.VersionApi.get_code()` succeeds against the cluster.
+- **Source**: `src/aiperf/kubernetes/preflight_checks.py:check_cluster_connectivity`
+- **Fails if**: kubeconfig missing, cluster unreachable, TLS error, or auth rejected
+  in a noninteractive session. In an interactive terminal (both stdin and stdout are
+  TTYs), an apiserver `401` — or a kubeconfig load failure whose text matches a
+  refreshable OIDC/exec-provider auth failure — pauses while AIPerf reloads
+  kubeconfig on a capped exponential backoff until the normal external login is
+  completed; press **Ctrl-C** to stop waiting. HTTP 403 still fails immediately.
+- **Fix**: set `KUBECONFIG`, check `~/.kube/config`, complete the usual credential-
+  provider login, and verify VPN/tunnel and RBAC.
+
+This check is implicit for the operator (the operator is already in-cluster by the
+time handlers run). On CLI failure, the remaining checks are skipped.
+
+### Kubernetes Version
+
+- **Validates**: `major.minor >= 1.24` per `MIN_K8S_MAJOR`/`MIN_K8S_MINOR`
+  (`src/aiperf/operator/preflight/_common.py`).
+- **Source**: `src/aiperf/operator/preflight/_tier1.py:_check_kubernetes_version`,
+  `src/aiperf/kubernetes/preflight_checks.py:check_kubernetes_version`
+- **Fails if**: cluster runs Kubernetes < 1.24.
+- **Fix**: upgrade the control plane. Older versions lack JobSet support and
+  sub-resource patch semantics the operator depends on.
+
+### JobSet CRD
+
+- **Validates**: `jobset.x-k8s.io/v1alpha2` CRD is registered and responds to
+  `list_cluster_custom_object` (operator) or `read_custom_resource_definition` (CLI).
+- **Source**: `src/aiperf/operator/preflight/_tier1.py:_check_jobset_crd`,
+  `src/aiperf/kubernetes/preflight_checks.py:check_jobset_crd`
+- **Fails if**: the CRD is not installed (HTTP 404). Any other HTTP error also
+  fails — JobSet is a hard prerequisite, so neither side downgrades to a warning.
+- **Fix**: install JobSet per the install-hint emitted in the failure message.
+  See [Getting Started](getting-started.md) for full install steps.
+  Example: `kubectl apply --server-side -f https://github.com/kubernetes-sigs/jobset/releases/latest/download/manifests.yaml`.
+
+## Check catalog — Tier 2 (blocking, RBAC)
+
+### RBAC Permissions
+
+- **Validates**: every `(verb, resource, group)` in `OPERATOR_RBAC_PERMISSIONS`
+  (operator) or `REQUIRED_RBAC_PERMISSIONS` (CLI) resolves `allowed=true` via
+  `SelfSubjectAccessReview`.
+- **Source**: `src/aiperf/operator/preflight/_tier1.py:_check_rbac_permissions`,
+  `src/aiperf/kubernetes/preflight_checks.py:check_rbac_permissions`,
+  `src/aiperf/operator/preflight/_common.py:OPERATOR_RBAC_PERMISSIONS`
+- **Fails if**: any permission probe returns `allowed=false`. Missing permissions are
+  listed as `<verb> <group>/<resource>` (core-group resources have no `<group>/`
+  prefix). A probe that raises instead — apiserver timeout, 5xx, or a
+  `SelfSubjectAccessReview` response with no `status` block — is classified as
+  transient and downgrades the check to `warn`, never `fail`.
+- **Fix**: bind a Role or ClusterRole granting the listed verbs on the namespace.
+  The operator Helm chart installs these by default
+  (`deploy/helm/aiperf-operator/templates/clusterrole.yaml` and
+  `benchmark-rbac.yaml`); the benchmark-pod Role is also built in code by
+  `RBACSpec._RULES` in `src/aiperf/kubernetes/resources.py`.
+
+Operator permission set (15 verbs over 8 resources): configmaps, roles,
+rolebindings, pods, pods/log, events (all core / rbac), jobsets, jobsets/status
+(jobset group). CLI requires a subset of 8.
+
+`SelfSubjectAccessReview` reviews *the caller's* identity, so this check covers
+the operator ServiceAccount (operator path) or your kubeconfig user (CLI path).
+It does not probe the benchmark pods' ServiceAccount, whose narrower Role is
+built separately in code by `RBACSpec._RULES` in
+`src/aiperf/kubernetes/resources.py` — see
+[RBAC and Security](rbac-security.md#operator-created-per-job-role). In
+particular, `create jobsets` appearing in the list above is a requirement on the
+caller, never on a benchmark pod.
+
+## Check catalog — Tier 3 (concurrent, infra)
+
+### Namespace (CLI only)
+
+- **Validates**: the target namespace already exists. AIPerf never creates
+  namespaces, so "you could create it" is not a pass.
+- **Source**: `src/aiperf/kubernetes/preflight_checks.py:check_namespace`
+- **Status**:
+  - `pass` — namespace exists.
+  - `fail` — namespace missing, or a non-404/403 HTTP error.
+  - `skip` — 403 on `read_namespace` (cannot verify; the namespace may still work).
+- **Fix**: `kubectl create namespace <ns>`, or have an admin do so, then re-run.
+
+### JobSet Controller
+
+- **Validates**: a deployment containing `"jobset"` in its name exists in
+  `jobset-system` and has `ready_replicas > 0`.
+- **Source**: `src/aiperf/operator/preflight/_infra.py:_check_jobset_controller`,
+  `src/aiperf/kubernetes/preflight_checks.py:check_jobset_controller`
+- **Status**:
+  - `pass` — deployment found and ready.
+  - `warn` — deployment found but not ready.
+  - `warn` — deployment not found (CLI: `fail`).
+  - `skip` — cannot list `jobset-system` (403).
+- **Fix**: `kubectl get pods -n jobset-system` to diagnose; reinstall the JobSet
+  controller if missing.
+
+### AIPerf Operator (CLI only)
+
+- **Validates**: the `AIPerfJob` CRD is registered and an AIPerf operator pod can
+  be found cluster-wide.
+- **Source**: `src/aiperf/kubernetes/preflight_checks.py:check_aiperf_operator`
+- **Status**: `pass` when a running operator pod is found; `warn` when the CRD or
+  pod cannot be verified, including a forbidden cluster-wide pod list. Direct-mode
+  submission does not require the operator.
+- **Fix**: install or diagnose the operator, grant cluster-wide pod-list access to
+  verify it, or submit with `--direct`.
+
+### Service Account (operator only)
+
+- **Validates**: if `spec.podTemplate.serviceAccountName` is set, the named service
+  account exists in the target namespace.
+- **Source**: `src/aiperf/operator/preflight/_infra.py:_check_service_account`
+- **Status**:
+  - `skip` — no custom service account configured (operator uses default).
+  - `pass` — service account exists.
+  - `fail` — 404 on `read_namespaced_service_account`.
+  - `warn` — any other API error (cannot verify).
+- **Fix**: `kubectl create serviceaccount <name> -n <namespace>`.
+
+### DNS Resolution
+
+- **Validates**: a `kube-system` deployment carrying the canonical
+  `k8s-app=kube-dns` label exists and is ready. The label is matched rather than a
+  `"coredns"` name substring so sibling deployments like `coredns-monitoring` do
+  not satisfy the check. Workers resolve the controller's DNS name for ZMQ
+  connections, so a broken DNS plane is a silent killer.
+- **Source**: `src/aiperf/operator/preflight/_infra.py:_check_dns`,
+  `src/aiperf/kubernetes/preflight_checks.py:check_dns`
+- **Status**: `pass` if ready, `warn` if found-but-not-ready or not found. The
+  operator returns `skip` on a 403 listing `kube-system`; the CLI reports any
+  API error — 403 included — as `warn`.
+- **Fix**: `kubectl get pods -n kube-system -l k8s-app=kube-dns`.
+
+### Network Policies
+
+- **Validates**: enumerates `NetworkPolicy` objects in the target namespace.
+- **Source**: `src/aiperf/operator/preflight/_infra.py:_check_network_policies`,
+  `src/aiperf/kubernetes/preflight_checks.py:check_network_policies`
+- **Status**:
+  - `pass` — no policies (pod-to-pod traffic unrestricted).
+  - `warn` — at least one policy exists; lists all by name. AIPerf pods need
+    multi-port TCP intra-namespace traffic, so restrictive policies can silently
+    break the ZMQ mesh.
+  - `skip` — 403.
+- **Fix**: ensure policies allow ingress/egress within the namespace on ZMQ ports.
+
+### Kueue Queue (operator only)
+
+- **Validates**:
+  - If `spec.scheduling.queueName` is set: the named `LocalQueue` exists in the
+    namespace.
+  - If not set and Kueue is installed: the namespace has the
+    `kueue.x-k8s.io/default-queue-name` annotation.
+- **Source**: `src/aiperf/operator/preflight/_infra.py:_check_kueue_queue`
+- **Status**:
+  - `pass` — queue exists, or namespace has default-queue annotation.
+  - `fail` — explicit `queueName` set but Kueue is not installed or the
+    `LocalQueue` is not found.
+  - `skip` — Kueue CRD not installed and no queue was requested.
+  - `warn` — Kueue installed, no queue configured; job will bypass gang-scheduling.
+- **Fix**: create the `LocalQueue`, set `scheduling.queueName`, or annotate the
+  namespace with `kueue.x-k8s.io/default-queue-name`.
+
+### Pod Security Admission (operator only)
+
+- **Validates**: reads the `pod-security.kubernetes.io/enforce` label on the
+  namespace. AIPerf pods run as non-root (UID 1000) with
+  `seccomp=RuntimeDefault` and drop all capabilities, so they are compatible with
+  `privileged` and `baseline`. The `restricted` level adds further constraints
+  (runAsNonRoot, allowPrivilegeEscalation=false, locked seccomp/capabilities, no
+  host paths) that the AIPerf pod template has not been fully audited against.
+- **Source**: `src/aiperf/operator/preflight/_infra.py:_check_pod_security_admission`
+- **Status**:
+  - `pass` — no PSA label, or label is `privileged` or `baseline`.
+  - `warn` — label is `restricted` (not yet verified compatible) or unknown PSA
+    level, or namespace lookup failed.
+- **Fix**: usually informational; relabel the namespace if the enforced level
+  blocks pod creation.
+
+## Check catalog — Tier 3 (concurrent, resources)
+
+Four checks — `Node Resources`, `Per-Node Schedulability`, `Resource Quotas`, and
+`Memory Estimation` — are short-circuited to `skip` when `spec.resourceMode=none`
+(controller and worker CPU/mem requests and limits are intentionally omitted).
+`Node Selector Match` and `Tolerations` inspect placement rather than capacity and
+still run. See `OperatorPreflightChecker._resource_mode_skip`.
+
+### Node Resources
+
+- **Validates**: free CPU and memory across Ready, uncordoned nodes is at least
+  the deployment's estimated requirement (controller pods + `workers * worker-pod`).
+  The CLI check subtracts the resource *requests* of all Running pods
+  (`list_pod_for_all_namespaces`) from each node's allocatable, so a
+  95%-booked cluster no longer reports full capacity; nodes with
+  `spec.unschedulable` (cordoned) are excluded entirely. When the pod list is
+  unavailable — typically a user without cluster-wide pod read — the check falls
+  back to raw allocatable and says so in its details rather than silently
+  overstating free space. The operator additionally excludes Ready nodes whose
+  `NoSchedule` / `NoExecute` taints are not tolerated by
+  `spec.podTemplate.tolerations`, so a cluster of all-tainted GPU nodes does not
+  report false capacity for a CPU-only workload.
+- **Source**: `src/aiperf/operator/preflight/_resources.py:_check_node_resources`,
+  `src/aiperf/kubernetes/preflight_capacity_checks.py:check_node_resources`
+- **Status**:
+  - `pass` — cluster has sufficient aggregate free capacity and at least one node
+    can fit the single largest pod (CLI combined check).
+  - `warn` — aggregate shortfall. Message includes required vs. available CPU/mem.
+    The CLI also warns when every node is individually too booked right now to
+    fit the largest pod, since those pods stay Pending until capacity frees up.
+    The operator also warns when no nodes exist at all, or when no node is both
+    Ready and schedulable.
+  - `fail` (CLI only) — no nodes in the cluster, or no single node can fit any
+    one pod even when empty (a structural sizing problem rather than a transient
+    booking). (The operator covers the per-node case with `Per-Node
+    Schedulability` instead.)
+- **Fix**: reduce worker count, add nodes, or right-size the pods via
+  `AIPERF_K8S_WORKER_POD_*` and the per-container control-plane resource vars
+  (`AIPERF_K8S_SYSTEM_CONTROLLER_*`, `AIPERF_K8S_RECORDS_MANAGER_*`, etc.).
+  There is no `AIPERF_K8S_CONTROLLER_POD_*` variable — `AIPERF_CONTROLLER_POD`
+  is only a boolean marker that tells a pod it is running the controller role.
+
+### Node Selector Match (operator only)
+
+- **Validates**: at least one Ready node has labels matching every
+  key/value pair in `spec.podTemplate.nodeSelector`.
+- **Source**: `src/aiperf/operator/preflight/_resources.py:_check_node_selector_match`
+- **Status**:
+  - `skip` — no `nodeSelector` specified.
+  - `pass` — one or more nodes match.
+  - `fail` — no Ready nodes match the selector.
+- **Fix**: label an existing node (`kubectl label node <name> key=value`) or drop
+  the selector from the CR.
+
+### Per-Node Schedulability (operator only)
+
+- **Validates**: at least one Ready node (matching any `nodeSelector`) has
+  allocatable capacity to fit the single largest pod in the deployment (max of
+  controller-pod and worker-pod CPU/mem).
+- **Source**: `src/aiperf/operator/preflight/_resources.py:_check_per_node_schedulability`
+- **Status**:
+  - `pass` — at least one node can fit the largest pod.
+  - `fail` — no node can; reports the largest pod size in the message.
+- **Fix**: add larger nodes or reduce per-pod requests/limits.
+
+### Resource Quotas
+
+- **Validates**: for each `ResourceQuota` in the namespace, projected CPU and memory
+  usage after the benchmark deploys stays under the hard limit.
+- **Source**: `src/aiperf/operator/preflight/_resources.py:_check_resource_quotas`,
+  `src/aiperf/kubernetes/preflight_capacity_checks.py:check_resource_quotas`
+- **Status**:
+  - `pass` — no quotas, or (operator) all quotas have headroom.
+  - `info` (CLI) — quotas exist, headroom available; details list each quota.
+  - `fail` (operator) — at least one quota would be exceeded. Message calls out
+    which resource and the overage.
+  - `warn` (CLI) — the same overage, reported non-blocking so a quota that does
+    not actually apply cannot stop a local run; details list each quota plus the
+    projected requirement.
+  - `warn` — the quota list could not be read, or a quota quantity could not be
+    parsed.
+- **Fix**: request a quota increase, reduce worker count, or deploy to a
+  different namespace.
+
+### Memory Estimation (operator only)
+
+- **Validates**: runs `aiperf.kubernetes.memory_estimator.estimate_memory` with the
+  resolved config, total workers, and connections-per-worker. Flags configurations
+  that are predicted to OOM.
+- **Source**: `src/aiperf/operator/preflight/_resources.py:_check_memory_estimation`
+- **Status**:
+  - `pass` — estimator returned no warnings.
+  - `warn` — estimator produced warnings; hints are the estimator's own
+    recommendations.
+- **Fix**: follow the estimator hints — usually reduce concurrency, reduce
+  dataset size, or raise the pod memory ceiling via `AIPERF_K8S_*_MEMORY`.
+
+### Tolerations (operator only)
+
+- **Validates**: if `spec.podTemplate.tolerations` is set, at least one node has
+  a taint whose `key` matches a configured toleration key.
+- **Source**: `src/aiperf/operator/preflight/_resources.py:_check_tolerations`
+- **Status**:
+  - `skip` — no tolerations configured.
+  - `pass` — at least one tainted node matches.
+  - `warn` — no matching tainted nodes (tolerations may be unnecessary).
+- **Fix**: either taint the intended nodes or remove the tolerations from the CR.
+
+## Check catalog — Tier 3 (concurrent, workload)
+
+### Secrets
+
+- **Validates** (operator): every secret referenced by the pod template —
+  `imagePullSecrets`, `volumes[].secret.secretName`, and
+  `env[].valueFrom.secretKeyRef.name` — exists in the namespace; required
+  `secretKeyRef.key` entries must also be present. References marked
+  `optional: true` retain Kubernetes' optional-secret semantics.
+- **Validates** (CLI): only the names passed on the command line via
+  `--image-pull-secret` and `--secret`. The CLI has no pod template to walk and
+  does not check individual secret keys.
+- **Source**: `src/aiperf/operator/preflight/_workload.py:_check_secrets`,
+  `src/aiperf/kubernetes/preflight_capacity_checks.py:check_secrets`
+- **Status**:
+  - `skip` — no secrets referenced (operator) or none passed on the CLI.
+  - `pass` — all secrets readable.
+  - `fail` — a required secret returned 404 (or another non-403 error) or a
+    required key is absent.
+  - `warn` — at least one secret returned 403 (cannot verify).
+- **Fix**: `kubectl create secret -n <namespace>` for missing names, or grant
+  `get secrets` to the caller.
+
+### Image Reference (operator) / Image Pull (CLI)
+
+- **Validates**: the configured image has a well-formed reference and a pull path
+  that is plausibly authenticated. Neither side contacts the registry.
+- **Source**: `src/aiperf/operator/preflight/_workload.py:_check_image_reference`,
+  `src/aiperf/kubernetes/preflight_capacity_checks.py:check_image`
+- **Operator (`Image Reference`)** — `fail` on an empty image; `warn` on either an
+  implicit `:latest` tag (neither tag nor digest present — inconsistent deployments
+  across reconciles) or a registry outside `PUBLIC_REGISTRIES` (`docker.io`,
+  `registry-1.docker.io`, `ghcr.io`, `quay.io`, `nvcr.io`, `registry.k8s.io`) with
+  no `imagePullSecrets` configured; otherwise `pass`.
+- **CLI (`Image Pull`)** — `skip` when no `--image` was passed; `pass` when
+  `--image-pull-secret` was supplied; `info` for a public registry; `warn`
+  otherwise, hinting that the registry may need credentials. The CLI reports an
+  implicit `latest` tag as a detail line only, not as a warning.
+- **Fix**: pin an explicit tag; add `imagePullSecrets` for private registries.
+
+### ConfigMap Size (operator only)
+
+- **Validates**: the generated benchmark ConfigMap's data payload fits within
+  Kubernetes' 1 MiB per-ConfigMap limit (`CONFIGMAP_MAX_SIZE_BYTES`).
+- **Source**: `src/aiperf/operator/preflight/_workload.py:_check_configmap_size`
+- **Status**:
+  - `pass` — size below 1 MiB; exact byte count reported.
+  - `fail` — over 1 MiB (API server would reject the Create), or the size could
+    not be computed at all.
+- **Fix**: reduce input-dataset size, move large fixtures to a `PersistentVolume`,
+  or drop optional config fields.
+
+### Dry Run (operator only)
+
+- **Validates**: posts the generated JobSet manifest with `dryRun=All`. Catches
+  admission-time rejections (OPA/Gatekeeper, validating webhooks, schema errors)
+  before the CR is admitted.
+- **Source**: `src/aiperf/operator/preflight/_workload.py:_check_dry_run`
+- **Status**:
+  - `pass` — API server accepts the manifest.
+  - `fail` — API server rejects; error body is parsed and surfaced.
+  - `warn` — transient network/timeout error.
+- **Fix**: read the API server's error message; usually points to a missing
+  label, a forbidden field, or an admission-controller rule.
+
+### Endpoint Connectivity (CLI only)
+
+- **Validates**: the `--endpoint-url` is reachable. For `*.svc` / `*.svc.cluster.local`
+  hosts, looks up the corresponding `Service` in the cluster. For external URLs,
+  only parses the URL and reports `info` — actual egress cannot be tested from the CLI.
+- **Source**: `src/aiperf/kubernetes/preflight_checks.py:check_endpoint_connectivity`
+- **Status**:
+  - `skip` — no `--endpoint-url` passed.
+  - `pass` — cluster service exists.
+  - `fail` — cluster service not found.
+  - `info` — external URL; connectivity verified later at runtime.
+  - `warn` — the URL could not be parsed.
+- **Fix**: `kubectl get svc -A | grep <service>`.
+
+## Skipping preflight
+
+### Skipping the endpoint reachability probe
+
+Endpoint reachability has a single operator-side probe. In the create handler,
+after spec validation and before the preflight tiers run, the operator calls
+`_check_endpoint_reachable` and records an `EndpointReachable` condition. Passing
+`--skip-endpoint-check` on
+`aiperf kube profile` serializes `spec.skipEndpointCheck: true` for an
+operator-managed AIPerfJob, so the operator skips this probe and proceeds
+without setting the condition.
+
+Direct `--no-operator` mode accepts `--skip-endpoint-check` for CLI parity but
+does not perform a client-side endpoint reachability probe, so the flag has no
+effect in that mode.
+
+```bash
+aiperf kube profile --model Qwen/Qwen3-0.6B \
+    --url http://vllm.models.svc.cluster.local:8000 \
+    --image nvcr.io/nvidia/aiperf:25.04 \
+    --skip-endpoint-check
+```
+
+Source: `src/aiperf/cli_commands/kube/profile.py` (CLI option),
+`src/aiperf/cli_commands/kube/profile_deploy.py` (CR spec propagation),
+`src/aiperf/cli_commands/kube/profile_deploy_direct.py` (direct-mode no-op),
+`src/aiperf/kubernetes/crd_models.py` (`skip_endpoint_check` field on
+`AIPerfWorkloadSpec`), and `src/aiperf/operator/handlers/create.py`
+(`_check_endpoint_reachable`).
+
+### `spec.resourceMode=none`
+
+Setting `resourceMode: none` on the `AIPerfJob` spec causes the operator's
+resource-capacity checks (`Node Resources`, `Per-Node Schedulability`,
+`Resource Quotas`, `Memory Estimation`) to return `skip`. Use this when pod
+resource requests and limits are intentionally omitted so the scheduler can
+fit pods anywhere. See `OperatorPreflightChecker._resource_mode_skip`.
+
+### Per-check skip conditions
+
+Several checks `skip` automatically when they have nothing to validate:
+
+| Check | Skips when |
+|---|---|
+| Service Account | `serviceAccountName` not set |
+| Node Selector Match | `nodeSelector` not set |
+| Tolerations | `tolerations` not set |
+| Secrets | no secrets referenced |
+| Kueue Queue | Kueue CRD not installed *and* no `scheduling.queueName` requested |
+| Endpoint Connectivity (CLI) | `--endpoint-url` not passed |
+| Image Pull (CLI) | `--image` not passed |
+
+### `AIPERF_PREFLIGHT_TIMEOUT`
+
+Increase the whole-preflight timeout if your cluster is slow to respond:
+
+```bash
+export AIPERF_PREFLIGHT_TIMEOUT=90
+```
+
+Default: 30 s. Range: 0 (exclusive) to 120 s. Set on the operator pod's
+environment — not on the CLI. See `src/aiperf/operator/environment.py:367`.
+
+## Exit codes
+
+`aiperf kube preflight` exits based on the aggregated `PreflightResults`:
+
+| Condition | Exit code |
+|---|---|
+| All checks `pass` / `skip` / `info` | `0` |
+| At least one `warn`, no `fail` | `0` (`has_warnings=true` in JSON) |
+| At least one `fail` | `1` |
+
+Source: `src/aiperf/cli_commands/kube/preflight.py` — `if not results.passed:
+raise SystemExit(1)`. `results.passed` is false iff any check status is `fail`.
+Warnings never block.
+
+With `-o json`, stdout carries only the JSON document on every exit path;
+the human-readable failure summary goes to stderr. A CI job can therefore
+consume both streams independently:
+
+```bash
+aiperf kube preflight -o json > preflight.json || echo "preflight failed"
+jq -e '.passed' preflight.json
+```

+
+# Production Deployments
+
+This guide covers patterns for running AIPerf benchmarks in production environments -- CI/CD pipelines, Kueue-managed clusters, private registries, GitOps workflows, and multi-tenant setups.
+
+---
+
+## CI/CD Integration
+
+### Detach Mode
+
+In non-interactive environments (CI pipelines, cron jobs), AIPerf automatically detaches after deploying. You can also force this explicitly:
+
+```bash
+aiperf kube profile \
+  --config benchmark.yaml \
+  --image nvcr.io/nvidia/aiperf:latest \
+  --detach
+```
+
+After deploying, poll for completion:
+
+```bash
+# Wait for the job to complete
+while true; do
+  PHASE=$(aiperf kube list my-benchmark 2>/dev/null | awk 'NR==2{print $3}')
+  [ "$PHASE" = "Completed" ] || [ "$PHASE" = "Failed" ] && break
+  sleep 30
+done
+
+# Download results
+aiperf kube results my-benchmark --output ./artifacts
+```
+
+`aiperf kube results` exits nonzero when the job cannot be resolved or the
+requested download is incomplete, so CI artifact steps fail instead of
+silently publishing an empty or partial directory.
+
+### JSON-Based Monitoring
+
+For automated pipelines, use JSON output:
+
+```bash
+# Preflight check with exit code
+aiperf kube preflight -o json
+echo "Exit code: $?"    # 0 = all checks passed, 1 = failures
+
+# Validation with structured output (takes AIPerfJob/AIPerfSweep CRs, not --config files)
+aiperf kube validate -o json aiperfjob.yaml
+
+```
+
+### Example GitHub Actions Workflow
+
+```yaml
+jobs:
+  benchmark:
+    runs-on: self-hosted
+    steps:
+      - uses: actions/checkout@v4
+
+      - name: Preflight check
+        run: |
+          aiperf kube preflight \
+            --endpoint-url http://dynamo-agg-frontend.dynamo-server.svc:8000/v1 \
+            -o json
+
+      - name: Run benchmark
+        run: |
+          aiperf kube profile \
+            --config benchmark.yaml \
+            --image nvcr.io/nvidia/aiperf:${{ github.sha }} \
+            --name "ci-${{ github.run_number }}" \
+            --detach
+
+      - name: Wait for completion
+        run: |
+          kubectl wait --for=condition=Complete \
+            aiperfjob/ci-${{ github.run_number }} --timeout=60m
+
+      - name: Collect results
+        if: always()
+        run: aiperf kube results ci-${{ github.run_number }} --output ./artifacts
+
+      - uses: actions/upload-artifact@v4
+        if: always()
+        with:
+          name: benchmark-results
+          path: ./artifacts/
+```
+
+---
+
+## GitOps Workflows
+
+### Generate Manifests for Version Control
+
+Instead of deploying from the CLI, generate Kubernetes manifests and commit them to your GitOps repository:
+
+```bash
+# Generate an AIPerfJob CR (operator mode)
+aiperf kube generate --operator \
+  --config benchmark.yaml \
+  --image nvcr.io/nvidia/aiperf:latest \
+  > deploy/aiperfjob.yaml
+
+# Or generate raw manifests (no operator needed)
+aiperf kube generate --no-operator \
+  --config benchmark.yaml \
+  --image nvcr.io/nvidia/aiperf:latest \
+  > deploy/manifests.yaml
+```
+
+Commit the generated YAML and let ArgoCD, Flux, or your GitOps tool apply it.
+
+### Operator Mode vs. Raw Manifests
+
+| Feature | Operator Mode | Raw Manifests |
+|---------|--------------|---------------|
+| Output | Single AIPerfJob CR | Namespace + RBAC + ConfigMap + JobSet |
+| Requires | Operator installed | Only JobSet CRD |
+| Monitoring | Operator tracks phase/progress | Manual pod watching |
+| Results | Stored on operator PVC | Must retrieve before TTL |
+| Cancellation | `spec.cancel: true` | Delete the JobSet |
+| Conditions | Status conditions populated (`ConfigValid`, `EndpointReachable`, `PreflightPassed`, `ResourcesCreated`, `WorkersReady`, `BenchmarkRunning`, `ResultsAvailable`, `IndexUpdated`, `PreflightHasWarnings`, `Complete`, `Failed`) | None |
+
+Operator mode also persists the active pod startup blocker in
+`status.startupIssue`. This keeps the first-observed timestamp across operator
+restarts and lets CI distinguish a retryable capacity delay from a stable
+image, configuration, or placement failure before the terminal `Failed`
+condition is set.
+
+For production use, the operator mode is recommended.
+

+
+## Kueue Gang-Scheduling
+
+If your cluster uses [Kueue](https://kueue.sigs.k8s.io/) for resource management, AIPerf integrates with it for quota-managed gang-scheduling.
+
+### Submit to a Kueue Queue
+
+```bash
+aiperf kube profile \
+  --config benchmark.yaml \
+  --image nvcr.io/nvidia/aiperf:latest \
+  --queue-name gpu-benchmarks \
+  --priority-class high-priority
+```
+
+Or in YAML:
+
+```yaml
+spec:
+  scheduling:
+    queueName: gpu-benchmarks
+    priorityClass: high-priority
+```
+
+When a queue is specified:
+
+1. The JobSet is created in a suspended state
+2. Kueue evaluates quota availability
+3. Once resources are available, Kueue unsuspends the JobSet
+4. The operator detects the transition and monitors normally
+
+`aiperf kube list` shows Kueue suspension status:
+
+```bash
+aiperf kube list
+# Shows phase "Queued" while the JobSet awaits Kueue admission
+```
+
+---
+
+## Private Registries
+
+### Image Pull Secrets
+
+If your AIPerf image is in a private registry:
+
+```bash
+# Create the pull secret
+kubectl create secret docker-registry my-registry \
+  --docker-server=nvcr.io \
+  --docker-username='$oauthtoken' \
+  --docker-password='YOUR_TOKEN' \
+  -n my-benchmarks
+
+# Reference it when deploying
+aiperf kube profile ... --image-pull-secrets my-registry
+```
+
+Or in YAML:
+
+```yaml
+spec:
+  podTemplate:
+    imagePullSecrets:
+      - {name: my-registry}
+```
+
+### API Keys and Secrets
+
+Pass API keys to the benchmark pods without embedding them in the config:
+
+```bash
+# Create a secret with your API key
+kubectl create secret generic llm-api-key \
+  --from-literal=api-key='sk-...' \
+  -n my-benchmarks
+
+# Reference it as an environment variable. Name the pod variable, and pass
+# `<secret>/<key>` as its value.
+aiperf kube profile ... \
+  --env-from-secrets.OPENAI_API_KEY llm-api-key/api-key
+```
+
+`--env-from-secrets` is a mapping flag and accepts three equivalent spellings.
+`--annotations`, `--labels`, and `--env-vars` accept the same three:
+
+```bash
+--env-from-secrets.OPENAI_API_KEY llm-api-key/api-key   # dot-notation
+--env-from-secrets OPENAI_API_KEY=llm-api-key/api-key   # KEY=VALUE
+--env-from-secrets '{"OPENAI_API_KEY": "llm-api-key/api-key"}'  # JSON object
+```
+
+Repeat the flag to set more than one entry.
+
+Endpoint credentials are transported out of band from the benchmark
+ConfigMap. AIPerf writes only redacted placeholders to `run_config.json`, then
+each service restores the real values from Secret-backed environment
+variables at startup. A credentialed endpoint without the matching
+`valueFrom.secretKeyRef` mapping is rejected before the JobSet is created.
+
+| Endpoint credential | Secret-backed pod environment variable |
+|---|---|
+| `endpoint.apiKey` | `AIPERF_INJECTED_API_KEY` or `OPENAI_API_KEY` |
+| Sensitive headers such as `Authorization` or `X-API-Key` | `AIPERF_INJECTED_HEADERS` containing a JSON object of header strings |
+| URL userinfo such as `https://user:password@host` | `AIPERF_INJECTED_ENDPOINT_URLS` containing a JSON list of full URL strings |
+
+Do not use `--env-vars` for these values: literal pod environment values are
+not Secret-backed and fail the credential transport check.
+
+Or in YAML:
+
+```yaml
+spec:
+  podTemplate:
+    env:
+      - name: OPENAI_API_KEY
+        valueFrom:
+          secretKeyRef:
+            name: llm-api-key
+            key: api-key
+```
+
+### Mounting Secret Files
+
+For secrets that need to be files (e.g., certificates, tokens):
+
+```bash
+aiperf kube profile ... \
+  --secret-mounts '{"name": "tls-cert", "mount_path": "/certs/ca.pem", "sub_path": "ca.pem"}'
+```
+
+`--secret-mounts` accepts the same shapes `--tolerations` does: a single JSON
+object, a JSON array covering several mounts in one token, or the flag repeated
+once per mount.
+
+---
+
+## Node Placement
+
+### Target Specific GPUs
+
+```bash
+aiperf kube profile ... \
+  --node-selector '{"nvidia.com/gpu.product": "NVIDIA-A100-SXM4-80GB"}'
+```
+
+### Tolerate GPU Taints
+
+Many clusters taint GPU nodes. Add tolerations so benchmark pods can schedule there:
+
+```bash
+aiperf kube profile ... \
+  --tolerations '[{"key": "nvidia.com/gpu", "operator": "Exists", "effect": "NoSchedule"}]'
+```
+
+Or in YAML:
+
+```yaml
+spec:
+  podTemplate:
+    nodeSelector:
+      nvidia.com/gpu.product: "NVIDIA-A100-SXM4-80GB"
+    tolerations:
+      - key: nvidia.com/gpu
+        operator: Exists
+        effect: NoSchedule
+```
+
+---
+
+## Scaling Workers
+
+AIPerf distributes workers across pods automatically. The `--total-workers` flag sets the total number of workers. The system places 10 workers per pod by default:
+
+| `--total-workers` | Pods Created | Workers Per Pod |
+|-----------------|-------------|-----------------|
+| 10 | 1 | 10 |
+| 50 | 5 | 10 |
+| 100 | 10 | 10 |
+| 200 | 20 | 10 |
+
+A `--total-workers` value above the per-pod count that is not a multiple of it
+cannot be expressed as a JobSet of identical pods, so it is rejected with an
+error naming the two nearest usable totals. Keep the total a multiple of 10, or
+set `benchmark.runtime.workersPerPod` to change the packing factor -- there is
+no CLI flag for it. A total at or below the per-pod count runs on a single pod.
+
+Only an authored total is rejected. When you omit `--total-workers` and
+`benchmark.runtime.workers`, the count derived from `ceil(concurrency /
+connectionsPerWorker)` is rounded up to a whole number of pods instead, since
+failing on it would report a worker count you never chose.
+
+Each worker maintains up to `connectionsPerWorker` concurrent requests (default: 100). When you pass `--total-workers` explicitly, the CLI derives this from your concurrency and worker count: `connectionsPerWorker = ceil(concurrency / workers)`. Left unset, the relationship inverts and the worker count is derived instead: `workers = ceil(concurrency / connectionsPerWorker)`.
+
+For high-concurrency benchmarks, scale workers rather than increasing connections per worker. This distributes the load across pods and nodes.
+
+---
+
+## Results Server
+
+The operator includes a results server sidecar that provides HTTP access to stored results. This powers `aiperf kube results` (which retrieves from the operator's PVC by default) and provides analytics endpoints backed by the SQLite runs index (`.aiperf_index.sqlite` on the results volume).
+
+### Available Endpoints
+
+After the operator is running:
+
+```bash
+# Port-forward to the results server
+kubectl port-forward -n aiperf-system svc/aiperf-operator 8081:8081
+
+# List stored results
+curl localhost:8081/api/v1/results
+
+# Get summary for a specific job
+curl localhost:8081/api/v1/analytics/summary/my-benchmarks/my-benchmark
+
+# Leaderboard across all benchmarks
+curl localhost:8081/api/v1/analytics/leaderboard
+
+# Compare two runs (repeat the jobs parameter, one per job)
+curl "localhost:8081/api/v1/analytics/compare?jobs=run-a&jobs=run-b"
+
+# Job history
+curl "localhost:8081/api/v1/analytics/history?model=Qwen/Qwen3-0.6B"
+```
+
+### Storage Configuration
+
+Results are stored on the operator's PVC. Configure retention in the Helm values:
+
+```yaml
+operator:
+  env:
+    resultsTtlDays: "30"           # auto-cleanup after 30 days
+    resultsCompressOnDisk: "true"  # zstd compression
+
+storage:
+  enabled: true                    # default; backs results in a PVC so they survive pod restarts
+  size: 1Ti                        # only used when enabled: true
+  storageClassName: ""             # cluster default; only used when enabled: true
+```
+
+`spec.resultsTtlDays` overrides this default per AIPerfJob or AIPerfSweep. A
+sweep persists the selected value in each epoch's aggregate, so cleanup remains
+effective after Kubernetes deletes the parent CR. Cleanup also removes the
+corresponding sweep index rows and repairs the sweep's `latest.txt` pointer.
+
+### Exposing Results Outside the Cluster (Ingress)
+
+By default the results server is reachable only via `ClusterIP + kubectl port-forward`. To expose it through an Ingress (e.g. for a shared dashboard link), enable `ingress.*` in the Helm values:
+
+```yaml
+ingress:
+  enabled: true
+  className: "nginx"          # empty uses the cluster default IngressClass
+  annotations: {}
+  hosts:
+    - host: aiperf.example.com
+      paths:
+        - path: /
+          pathType: Prefix    # backend port defaults to resultsServer.port (8081)
+  tls: []                     # optional: list of {hosts: [...], secretName: ...}
+```
+
+The template lives at `deploy/helm/aiperf-operator/templates/ingress.yaml` and routes to the operator Service on `resultsServer.port`. Each path may override the backend port via `portNumber`.
+
+---
+
+## Environment Variables
+
+Fine-tune benchmark behavior with environment variables in the pod template:
+
+```yaml
+spec:
+  podTemplate:
+    env:
+      - name: AIPERF_HTTP_CONNECTION_LIMIT
+        value: "200"
+      - name: AIPERF_HTTP_KEEPALIVE_TIMEOUT
+        value: "120"
+```
+
+Probe tunables such as `AIPERF_K8S_HEALTH_STARTUP_PERIOD_SECONDS` and
+`AIPERF_K8S_HEALTH_STARTUP_FAILURE_THRESHOLD` do not belong here. They are read
+by whichever process renders the JobSet -- the operator pod, or the CLI in
+direct mode -- and baked into the pod spec's probe fields before the benchmark
+container exists. Setting them under `spec.podTemplate.env` has no effect; set
+them on the operator Deployment (or in the CLI's own environment) instead.
+
+There is no `AIPERF_HTTP_TIMEOUT` variable; set the per-request timeout with
+the `--request-timeout-seconds` CLI flag (or `request_timeout_seconds` in the
+benchmark config) instead. See the
+[Environment Variables Reference](../environment-variables.md) for the full list.
+
+---
+
+## Multi-Tenant Clusters
+
+### Operator Scope and Namespace Ownership
+
+An operator install is one of two things, decided by `operator.id`:
+
+| | `operator.id` | Namespaces watched | Writes a claim |
+|---|---|---|---|
+| **Global operator** | `""` (default) | all, or `operator.watchNamespaces` | no |
+| **Scoped operator** | a unique string | `operator.watchNamespaces` | yes |
+
+A scoped operator claims each namespace it watches by writing a
+`coordination.k8s.io/v1` Lease named `aiperf-operator` into it, and renews that
+Lease on a timer. Every operator — the global one included — skips any
+namespace whose Lease is held by a different identity and still fresh. Nothing
+is set on the AIPerfJob itself, so a job cannot be submitted to the wrong
+operator by forgetting a label.
+
+This is what lets a scoped build run beside the production operator:
+
+```bash
+helm install aiperf-test deploy/helm/aiperf-operator \
+  --namespace aiperf-system-test --create-namespace \
+  --set operator.id=my-branch \
+  --set 'operator.watchNamespaces={aiperf-test}'
+```
+
+The global operator stops reconciling `aiperf-test` as soon as the claim lands,
+and resumes when the claim lapses. `aiperf kube list` shows the holder in its
+`OWNER` column; `-` means the global operator owns that namespace, and `?`
+means the claim could not be read (usually missing RBAC on `leases`).
+
+The global operator caches namespace ownership and refreshes it every
+`AIPERF_OPERATOR_CLAIM_LEASE_SECONDS / 3` seconds (~100 s by default). During
+that window after a scoped operator starts, the global operator may briefly act
+on events in a newly-claimed namespace before its cache updates.
+
+Two scoped operators cannot claim the same namespace: the second one fails at
+startup naming the current holder, rather than silently double-reconciling.
+
+The claim's duration (`AIPERF_OPERATOR_CLAIM_LEASE_SECONDS`, default 300s) is
+deliberately long, so a crash-looping operator keeps its namespaces across
+restarts. Uninstalling a scoped operator lets its claims expire and the
+namespaces fall back to the global operator; nothing needs to be deleted by
+hand for ownership to transfer.
+
+The `aiperf-operator` Lease object itself does survive the uninstall in each
+watched namespace. It is expired, has no effect on ownership, and is only
+visible in `kubectl get leases`. Remove it manually if you want it gone:
+
+```bash
+kubectl delete lease aiperf-operator -n <namespace>
+```
+
+### Namespace Isolation
+
+Benchmarks run in the namespace you name with `--namespace`. For multi-tenant setups, give each team its own:
+
+```bash
+aiperf kube profile ... --namespace team-a-benchmarks --operator
+aiperf kube profile ... --namespace team-b-benchmarks --operator
+```
+
+By default the operator watches all namespaces for AIPerfJob CRs; set
+`operator.watchNamespaces` in the Helm values to restrict it to a fixed list,
+and `operator.id` to also claim those namespaces away from a global operator
+(see [Operator Scope and Namespace Ownership](#operator-scope-and-namespace-ownership)).
+Each job gets its own RBAC scoped to its namespace. Here `--operator` bypasses cluster-scoped CRD
+discovery, and the namespaces must already exist -- the CLI never issues a
+Namespace-create request. A tenant therefore needs permission
+to create `AIPerfJob` resources in its namespace, not permission to read CRDs or
+create namespaces.
+
+The per-job Role grants no create, update, or delete verbs, so a compromised
+benchmark pod cannot launch workloads of its own. What it retains inside its
+namespace is read access to pod, ConfigMap, Service, Endpoint, Event, and Job
+metadata, plus `patch` on its own AIPerfJob and JobSet — which is why a
+namespace per team, rather than a shared benchmark namespace, is still the
+tenancy boundary. See
+[RBAC and Security](rbac-security.md#operator-created-per-job-role).
+
+If cluster policy forbids chart-managed cluster-scoped RBAC, install with
+`rbac.create=false`, `serviceAccount.create=false`, an explicit
+`serviceAccount.name`, and `tests.enabled=false`; that combination emits zero
+`ClusterRole`/`ClusterRoleBinding` objects. See
+[Eliminating all cluster-scoped RBAC](rbac-security.md#eliminating-all-cluster-scoped-rbac).
+
+### Resource Quotas
+
+The preflight checker validates resource quotas before deploying:
+
+```bash
+aiperf kube preflight --namespace team-a-benchmarks --workers 20
+```
+
+If the namespace has a ResourceQuota, preflight projects the total CPU and memory requirements and warns if deployment would exceed the quota.
+
+---
+
+## Operator Management
+
+### Upgrading
+
+```bash
+helm upgrade aiperf-operator deploy/helm/aiperf-operator \
+  --namespace aiperf-system
+```
+
+> **WARNING:** Drain active benchmarks before upgrading from a chart older than
+> 0.8.0. Those versions rendered the benchmark `Role` and `RoleBinding` into a
+> chart-owned `aiperf-benchmarks` namespace; the upgrade deletes that RBAC and
+> recreates it in the release namespace. A benchmark running in
+> `aiperf-benchmarks` at that moment loses its RBAC mid-flight and starts
+> failing its pod, ConfigMap, and JobSet reads. Wait for in-flight runs to
+> reach a terminal phase (`aiperf kube list`) before running `helm upgrade`.
+
+### Uninstalling
+
+```bash
+helm uninstall aiperf-operator --namespace aiperf-system
+```
+
+Both CRDs carry `helm.sh/resource-policy: keep`, so the `AIPerfJob` and `AIPerfSweep` CRDs -- and any existing custom resources -- survive the uninstall. To remove everything:
+
+```bash
+kubectl delete crd aiperfjobs.aiperf.nvidia.com
+kubectl delete crd aiperfsweeps.aiperf.nvidia.com
+kubectl delete namespace aiperf-system
+```
+
+### Monitoring the Operator
+
+Check operator logs:
+
+```bash
+kubectl logs -n aiperf-system -l app.kubernetes.io/name=aiperf-operator -f
+```
+
+The operator emits structured logs with job events, phase transitions, and error details.
+
+### Debugging Failed Jobs
+
+By default the operator cleans up JobSet pods once a job terminates, which makes postmortems hard. Set `keepFailedPods: true` on the AIPerfJob spec to preserve failed pod attempts for inspection:
+
+```yaml
+spec:
+  keepFailedPods: true   # default: false; retains failed JobSet pods for kubectl logs/exec
+```
+
+This changes JobSet lifecycle (completed pods still get reaped via `ttlSecondsAfterFinished`); enable it only while diagnosing, then remove for steady-state runs.
+
+### Deploying Before the Endpoint Is Reachable
+
+The operator runs a TCP/HTTP reachability probe against `spec.benchmark.endpoint` before spinning up workers. If the inference server isn't live yet at deploy time (e.g. GitOps applies the CR before the model pod is Ready), set `skipEndpointCheck: true` to bypass the probe:
+
+```yaml
+spec:
+  skipEndpointCheck: true   # default: false; skips the operator-side endpoint reachability probe
+```
+
+Workers will still fail fast if the endpoint never comes up -- this only suppresses the upfront check.

+
+AIPerf separates cluster-wide operator authority from per-namespace benchmark
+authority. The operator Deployment runs under a ServiceAccount bound to a
+`ClusterRole` so a single operator replica can watch `AIPerfJob` custom
+resources across the cluster and create JobSets in benchmark namespaces.
+The chart grants no `coordination.k8s.io/leases` rule because the operator
+implements no leader election at all: `operator.replicas` defaults to 1 and
+`templates/deployment.yaml` calls `fail` on any other value, so a
+leader-elected set is not merely undocumented but unrenderable.
+Benchmark pods (controllers, workers, record
+processors) run under the `default` ServiceAccount of their namespace, bound
+to namespace-scoped `Role`s so that nothing they hold reaches cluster scope.
+
+The split lets cluster admins pre-provision the operator's cluster-wide
+RBAC once (under a security review), then hand developers a `Role` template
+that cannot escalate beyond the benchmark namespace. Developers never touch
+cluster-scoped resources. Within a benchmark namespace, controller and worker
+pods share one ServiceAccount, so every pod holds the union of what the
+controller needs. Because that union is what a compromised worker inherits, it
+is held to exactly the operations a pod performs: `patch` on its own AIPerfJob
+and JobSet, and read-only access to everything else. No benchmark pod can
+create, replace, or delete any object. Namespace boundaries are still what
+separate tenants — see [Least-privilege recipe](#least-privilege-recipe).

+
+The operator owns JobSet/ConfigMap/Role creation in the benchmark namespace.
+Two distinct `Role`s apply to benchmark pods: the narrow chart-managed
+`aiperf-operator-benchmark` Role, and a broader per-job Role the operator
+creates on every reconcile. The effective grant is the union of the two --
+see [Benchmark-namespace Role catalog](#benchmark-namespace-role-catalog).

+| `""` (core) | `pods` | `get, list, watch` | Workers discover controller and peer record processors via pod labels | `benchmark-rbac.yaml:19-21` |
+| `jobset.x-k8s.io` | `jobsets` | `get, list, watch, patch` | Controller patches JobSet annotations to signal graceful completion | `benchmark-rbac.yaml:27-29` |
+| `aiperf.nvidia.com` | `aiperfjobs`, `aiperfjobs/status` | `get, list, watch, patch` | Controller reads AIPerfJob spec and patches per-phase progress fields | `benchmark-rbac.yaml:33-35` |
+
+This chart-managed Role grants no create, update, or delete verbs and no access
+to Secrets or Events. `patch` without `update` is deliberate: both writers issue
+JSON-patch requests against annotations and `status`, so the whole-object `PUT`
+that `update` authorizes is never needed and would let a pod rewrite `spec`.
+It is not, however, the whole grant.
+
+### Operator-created per-job Role
+
+On every AIPerfJob reconcile the operator also creates a `Role` named
+`<jobset>-role` and a `RoleBinding` named `<jobset>-binding` in the benchmark
+namespace, owned by the AIPerfJob CR so it is garbage-collected with the job.
+The rules live in `RBACSpec._RULES`
+(`src/aiperf/kubernetes/resources.py:211-269`); the create path is
+`_create_rbac` in `src/aiperf/operator/handlers/create.py:275-294`. The
+`RoleBinding` subject is `podTemplate.serviceAccountName`, falling back to
+`default`, so it lands on the same identity the benchmark pods run under.
+
+| API group | Resources | Verbs |
+|---|---|---|
+| `aiperf.nvidia.com` | `aiperfjobs`, `aiperfjobs/status` | `get, list, watch, patch` |
+| `""` (core) | `configmaps` | `get, list, watch` |
+| `""` (core) | `pods`, `pods/log` | `get, list, watch` |
+| `""` (core) | `services`, `endpoints` | `get, list, watch` |

+| `jobset.x-k8s.io` | `jobsets` | `get, list, watch, patch` |
+| `jobset.x-k8s.io` | `jobsets/status` | `get, list, watch` |
+
+The effective permission set for benchmark pods is the union of this Role and
+the chart-managed one, and `patch` on `aiperfjobs`/`aiperfjobs/status` and
+`jobsets` is the only write verb in it. Everything else is read-only.
+Benchmark pods have no access to Secrets, ServiceAccounts, or RBAC objects.
+
+Because controller and worker pods share one ServiceAccount and the token is
+mounted in every container, the grant is scoped to exactly what in-pod code
+calls:
+
+- **`aiperfjobs` `get`/`patch`** — `signal_benchmark_complete`
+  (`src/aiperf/kubernetes/completion_signal.py`) sets the
+  benchmark-complete annotation, and the controller pod's API container pushes
+  per-phase progress into `status` (`src/aiperf/api/routers/progress.py`).
+  Both patches are UID-fenced with a JSON-patch `test` op so a pod from a
+  replaced incarnation cannot mutate the current CR.
+- **`jobsets` `get`/`patch`** — the same API container writes JobSet
+  annotations, after verifying the JobSet's `ownerReferences` name the expected
+  AIPerfJob UID.
+- **`pods` `list`, `pods/log` `get`, `events` `list`** — peer discovery, the
+  heartbeat watchdog (`src/aiperf/kubernetes/watchdog_source.py`), and
+  cross-namespace server-metrics endpoint discovery.
+
+Nothing in a pod creates, replaces, or deletes anything. The run config arrives
+as a kubelet-mounted ConfigMap volume rather than an API read, the headless
+Service for pod DNS is provisioned by the JobSet controller via
+`network.enableDNSHostnames`, JobSet deletion is the operator's job
+(`delete_jobset` has no in-pod caller), and Events are emitted by the operator
+under its own ClusterRole. `create` on `jobsets` in particular used to be
+granted here; it let any compromised pod launch a JobSet, and therefore run
+arbitrary containers, under the benchmark ServiceAccount.
+
+Widening these verbs is a deliberate blast-radius change, and two mechanical
+guards make it fail CI: `TestRBACSpecLeastPrivilege` in
+`tests/unit/kubernetes/test_resources.py` pins the exact verb set per rule and
+rejects every mutating verb other than `patch`, and
+`test_helm_benchmark_rbac_is_subset_of_rbac_spec` in the same file requires the
+chart's benchmark Role to stay a subset of `RBACSpec._RULES`, so the Python and
+Helm copies cannot drift apart.
+
+What remains reachable from a compromised benchmark pod is status and annotation
+spoofing on its own job: it can report a false phase or a false completion, and
+it can read every pod, ConfigMap, Service, Endpoint, Event, and Job in the
+namespace. That is the concrete reason for the per-team namespace rule below.
+
+The one deliberate exception to namespace confinement is cross-namespace
+server-metrics discovery. Each entry in `serverMetricsDiscoveryNamespaces`
+renders a second, narrower `Role` (`<fullname>-metrics-discovery`, `pods:
+get/list/watch` only) in that inference namespace, bound back to the
+benchmark namespaces' ServiceAccounts. A plain string entry binds the
+`default` ServiceAccount; use the `{namespace, serviceAccounts}` object form
+when benchmark pods run under a custom `podTemplate.serviceAccountName`. The
+chart does not create those namespaces.
+
+## Credential redaction at metadata boundaries
+
+When endpoint configuration derived from an AIPerfJob CR crosses a persistence
+or display boundary, AIPerf redacts both the public YAML `apiKey` spelling and
+the internal `api_key` spelling, credential-bearing headers, URL userinfo, and
+sensitive URL query parameters. This applies to `job_spec.json`, the runs
+index (including its flattened endpoint), operator results/config/analytics
+API responses, Kubernetes events and status messages, JobSet endpoint
+annotations, preflight details, and CLI submission summaries. Redaction keeps
+non-secret URL host, path, and query context available for diagnosis.
+Legacy `job_spec.json` files are also sanitized when downloaded directly or as
+part of a result bundle; this compatibility protection does not rewrite the
+copy already stored on the results PVC.
+
+This boundary protection does not rewrite the source CR stored by the
+Kubernetes API server. Prefer Secret-backed endpoint credentials and restrict
+CR read permissions; do not rely on result/API redaction as storage encryption.
+Credentials cannot be Kubernetes sweep parameters: grid, zip, scenario,
+adaptive, Sobol, and Latin Hypercube axes that target credential fields or
+contain credential-bearing values are rejected before child creation. Keep
+endpoint credentials fixed and use the Secret-backed pod environment transport
+for every variation.
+
+## `rbac.create=false` workflow
+
+In security-sensitive clusters, RBAC is usually reviewed and committed
+separately from workload charts. Set `rbac.create=false` and
+`serviceAccount.create=false` to make the operator chart use a
+pre-provisioned `ServiceAccount` and skip both the `ClusterRole` + `ClusterRoleBinding`
+and the per-namespace `Role` + `RoleBinding`.
+
+```bash
+helm install aiperf-operator ./deploy/helm/aiperf-operator \
+  --namespace aiperf-system \
+  --set rbac.create=false \
+  --set serviceAccount.create=false \
+  --set serviceAccount.name=aiperf-operator-sa \
+  --set tests.enabled=false
+```
+
+`tests.enabled=false` is what makes the chart emit **zero** `ClusterRole` and
+`ClusterRoleBinding` objects; see
+[Eliminating all cluster-scoped RBAC](#eliminating-all-cluster-scoped-rbac).
+Omit it if you want `helm test` and accept the two `…-tests` cluster-scoped
+objects.
+
+The cluster admin applies the RBAC tree out-of-band. A minimal example
+mirroring the chart defaults:
+
+```yaml
+---
+# ServiceAccount in the operator namespace
+apiVersion: v1
+kind: ServiceAccount
+metadata:
+  name: aiperf-operator-sa

+```
+
+`rbac.create=false` only suppresses the chart's own RBAC. The operator still
+creates its per-job `Role` and `RoleBinding` on every reconcile (see
+[Operator-created per-job Role](#operator-created-per-job-role)), and those
+names are derived from the JobSet, so pre-provisioning the chart-named
+`aiperf-operator-benchmark` Role does not satisfy them. The admin-owned
+`ClusterRole` must therefore keep `create` on
+`rbac.authorization.k8s.io/roles` and `rolebindings`: only HTTP 409
+`AlreadyExists` is tolerated by `create_idempotent_role`
+(`src/aiperf/operator/k8s_helpers.py:201-234`), so a 403 aborts the reconcile
+and the job never starts. Do not trim those verbs, even for a single fixed
+namespace.
+
+### Eliminating all cluster-scoped RBAC
+
+`rbac.create=false` does not suppress the `helm test` hook RBAC, and
+deliberately so. With that flag alone the chart still creates an
+`<fullname>-tests` ServiceAccount, a namespaced `Role`/`RoleBinding`
+(`pods: get, list`), and a `ClusterRole`/`ClusterRoleBinding` scoped by
+`resourceNames` to the two AIPerf CRDs with `get` only
+(`deploy/helm/aiperf-operator/templates/tests/rbac.yaml`). The privilege is
+negligible, but a cluster whose policy is "this chart creates no cluster-scoped
+RBAC" needs a way to reach zero.
+
+Use `tests.enabled=false`:
+
+```bash
+$ helm template aiperf-operator ./deploy/helm/aiperf-operator \
+    --namespace aiperf-system \
+    --set rbac.create=false \
+    --set serviceAccount.create=false \
+    --set serviceAccount.name=aiperf-operator-sa \
+    --set tests.enabled=false \
+  | grep -c '^kind: Cluster'
+0
+```
+
+`tests.enabled` gates the hook Pods and their RBAC together, so neither is left
+referencing the other. `helm test` against a release installed this way prints
+`TEST SUITE: None` and exits 0 — an unambiguous "no tests were defined", not a
+failure.
+
+The flag is separate from `rbac.create` on purpose. `rbac.create=false` means
+"the operator's own RBAC is pre-provisioned out-of-band", which says nothing
+about the chart's smoke-test scaffolding. Folding them together would strip the
+test ServiceAccount while still rendering the hook Pods that name it, so
+`helm test` would fail on pod creation with a `serviceaccount not found` error
+instead of reporting that there is nothing to run.
+
+`test-crd-installed` reads cluster-scoped CustomResourceDefinitions, so its
+`ClusterRole` cannot be narrowed to a namespace — keeping `helm test` and
+reaching zero cluster-scoped RBAC are mutually exclusive. If you disable the
+hooks, run the equivalent checks out-of-band: `kubectl get crd
+aiperfjobs.aiperf.nvidia.com aiperfsweeps.aiperf.nvidia.com` and `aiperf kube
+preflight`.
+
+The helper
+`deploy/helm/aiperf-operator/templates/_helpers.tpl`'s
+`aiperf-operator.serviceAccountName` template resolves to `.Values.serviceAccount.name`
+when `serviceAccount.create` is false, so the operator Deployment will
+reference the pre-provisioned SA as expected.
+
+`serviceAccount.name` is **required** in that mode. Leaving it empty used to
+resolve to the namespace `default` ServiceAccount — an identity holding none of
+the operator's `ClusterRole` — so the install succeeded and the operator then
+403'd on every reconcile. The helper now fails the render instead:
+
+```
+Error: execution error at (aiperf-operator/templates/deployment.yaml:33:29):
+serviceAccount.name is required when serviceAccount.create=false. ...
+```
+
+Set `serviceAccount.name` to the pre-provisioned account named in your
+`ClusterRoleBinding` subject.
+
+## Pod `securityContext`
+
+Every container in both the controller and worker pods receives a
+hardened `securityContext` assembled by
+`build_security_context()` in `src/aiperf/kubernetes/jobset_helpers.py:19-51`.
+The base context applied to every container is:
+
+```yaml
+securityContext:
+  runAsNonRoot: true
+  runAsUser: 1000
+  runAsGroup: 1000
+  allowPrivilegeEscalation: false
+  readOnlyRootFilesystem: true
+  capabilities:
+    drop: ["ALL"]
+  seccompProfile:
+    type: RuntimeDefault
+```
+
+This context is applied to:
+
+- The five control-plane containers in the controller pod
+  (`jobset.py`)
+- The event-bus proxy sidecar (`jobset.py`)
+- The results-serving sidecar (`jobset.py`)
+- Each worker and record-processor container
+
+### Overriding via `podTemplate.containerSecurityContext`
+
+The CRD schema at
+`deploy/helm/aiperf-operator/templates/crd-aiperfjob.yaml:917` exposes
+`spec.podTemplate.containerSecurityContext` as a free-form object. Keys
+supplied there merge on top of the base context. `capabilities` is merged
+shallowly (user keys update the drop/add lists); all other keys are replaced.
+
+Privilege-escalating values cannot be merged in at all. `privileged: true`,
+`allowPrivilegeEscalation: true`, `runAsNonRoot: false`, `runAsUser: 0`, and
+`runAsGroup: 0` are rejected by `PodTemplateConfig` validation and dropped
+again by the builder as defense in depth -- see
+`privilege_escalating_keys()` in `src/aiperf/config/deployment.py`.
+
+Other keys **widen** the baseline rather than escalating privilege, and those
+are permitted and warned about rather than rejected -- a benchmark pod
+legitimately needs `SYS_ADMIN` for perf/profiling tooling, and
+`seccompProfile: Unconfined` is a normal requirement for GPU and tracing
+workloads. `risky_security_context_details()` in
+`src/aiperf/config/deployment.py` flags:
+
+| Construct | Effect on the baseline |
+|---|---|
+| `capabilities.add: [...]` | merged over `drop: ["ALL"]`, granting the listed capabilities |
+| `capabilities.drop` without `ALL` | narrows the dropped set |
+| `readOnlyRootFilesystem: false` | container root filesystem becomes writable |
+| `seccompProfile.type` != `RuntimeDefault` | e.g. `Unconfined` removes syscall filtering |
+
+The warning fires twice over a job's life, deliberately: once at CR validation
+(`PodTemplateConfig._reject_weakened_security_context`) and once on the merge
+path in `build_security_context()`, which is also reachable from templates
+constructed directly in code that never pass through Pydantic validation. The
+merge-path warning is deduplicated per distinct message, because
+`build_security_context()` runs once per container.
+
+Note that `capabilities` is intentionally exempt from the escalating-key filter
+in `build_security_context()` -- it is merged shallowly so `add` lists survive.
+Bound it at admission (step 12 of the least-privilege recipe) if your cluster
+must forbid it.
+
+```yaml
+apiVersion: aiperf.nvidia.com/v1alpha1
+kind: AIPerfJob
+metadata:
+  name: hardened-run
+spec:
+  podTemplate:
+    containerSecurityContext:
+      runAsUser: 65534
+      runAsGroup: 65534
+      capabilities:
+        drop: ["ALL"]
+        add: []
+  benchmark:
+    models: [meta-llama/Meta-Llama-3-8B-Instruct]
+    endpoint: {type: chat, url: https://llm.example.com/v1}
+    datasets:
+      - name: main
+        type: synthetic
+    phases:
+      - name: profiling
+        type: concurrency
+        concurrency: 10
+        requests: 100
+```
+
+### What `readOnlyRootFilesystem: true` requires
+
+The root filesystem is read-only. AIPerf writes to five locations, which
+must be provided as writable volumes. The JobSet builder already handles
+this: `build_shared_volumes()` declares them as pod-level `emptyDir`
+volumes and `build_volume_mounts()` attaches them to each container, both in
+`src/aiperf/kubernetes/jobset_helpers.py`. (The results-serving sidecar is the
+one exception -- it carries a hand-written mount list of read-only `/results`
+plus writable `/tmp`, which is all it needs.)
+
+- `/aiperf/ipc` — ZMQ IPC socket files (controller mode)
+- `/aiperf/datasets` — shared dataset mmap files (dataset-manager writes, API serves to workers)
+- `/aiperf/hf_home` — HuggingFace cache (`tokenizer-cache` volume; `HF_HOME` points here)
+- `/results` — exported metrics, profile artifacts
+- `/tmp` — general scratch (tempfile, matplotlib config)
+
+If you supply an alternate `podTemplate.volumeMounts`, ensure each of these
+paths is covered by a writable volume. Otherwise the controller will fail
+to bind IPC sockets on startup and pods will CrashLoopBackOff.
+
+## Unhardened passthroughs: `volumes` and `initContainers`
+
+AIPerf is a benchmarking tool first. `podTemplate.volumes` and
+`podTemplate.initContainers` are deliberately free-form passthroughs: GPU
+benchmarking legitimately needs `hostPath` mounts (device nodes, driver
+directories, local NVMe scratch), and init containers exist for sysctl tweaks
+(e.g. raising `ip_local_port_range`), model pre-fetch, and permission fixups.
+Neither field is restricted, and no construct is rejected.
+
+What AIPerf does instead is **validate and warn**, plus apply a safe default
+where one cannot break a workload:
+
+**Volumes.** `PodTemplateConfig` logs one WARNING per volume whose source
+reaches outside the pod sandbox (`hostPath`, `nfs`, `iscsi`, `cephfs`,
+`glusterfs`, `rbd`, `flexVolume` — see `RISKY_VOLUME_SOURCE_KEYS` in
+`src/aiperf/config/deployment.py`). The message names the field path, the volume
+name, and for `hostPath` the exact node path. A `hostPath` at the node root or
+under a credential/runtime directory (`/etc`, `/root`, `/var/run`, `/run`,
+`/var/lib/kubelet`, `/var/lib/docker`, `/var/lib/containerd`, `/proc`, `/boot`,
+`/home`) is additionally called out as exposing node credentials, the container
+runtime, or kubelet state. The volume is still rendered into the PodSpec.
+
+```
+podTemplate.volumes[0] ('node-root'): hostPath volume mounting node path '/'
+which exposes node credentials, the container runtime, or kubelet state to the
+benchmark pod. This is allowed - AIPerf benchmarks legitimately need host
+access - but it is not covered by AIPerf's pod hardening.
+```
+
+**Init containers.** An init container that declares **no** `securityContext`
+receives AIPerf's hardened container baseline as a default — the same context
+`build_security_context()` produces for regular containers, minus
+`readOnlyRootFilesystem` (init containers do not get AIPerf's writable emptyDir
+mount layout, and commonly write to the image filesystem). An init container
+that **does** declare a `securityContext` is passed through verbatim so
+privileged setup work stays possible; it is not merged key-by-key, because
+merging the baseline's `allowPrivilegeEscalation: false` under a user's
+`privileged: true` produces a combination the Kubernetes API rejects outright.
+Such a container is logged as a WARNING naming the escalating keys and any added
+capabilities. See `_build_init_containers()` in
+`src/aiperf/kubernetes/jobset_specs.py`.
+
+Note that the pod-level `securityContext` (`runAsNonRoot: true`,
+`runAsUser: 1000`, `seccompProfile: RuntimeDefault`) applies to init containers
+too unless they override it, so even a passthrough init container is non-root
+by default.
+
+If your cluster must forbid these constructs, enforce them at admission
+(PodSecurity `restricted`, or a Gatekeeper/Kyverno policy on `hostPath`) rather
+than expecting AIPerf to refuse the spec.
+
+## NetworkPolicy expectations
+
+The chart ships an opt-in `NetworkPolicy` template for the operator pod
+itself (`deploy/helm/aiperf-operator/templates/networkpolicy.yaml`, enabled
+via `networkPolicy.enabled=true`) — it restricts ingress to the health
+port 8080, the results-server port (`resultsServer.port`, default 8081), and
+the operator metrics port (`operator.metrics.port`, default 9090) and permits
+egress to DNS (kube-system UDP/TCP 53), the Kubernetes
+API server (443/6443), and the configured benchmark namespaces. See
+[Operator NetworkPolicy](#operator-networkpolicy) below. For benchmark-pod
+traffic — the flows listed in the table below — the chart does not ship a
+policy; policy is site-specific. When you enforce a default-deny policy
+in the benchmark namespace, allow:
+
+| Source | Destination | Ports | Reason |
+|---|---|---|---|
+| Worker pods | Controller pod | 5557, 5564, 5661/5662, 5663/5664, 5665/5666, 5667, 5668, 5669 (TCP) | ZMQ records push/pull (5557), credit router (5564), dataset-manager proxy DEALER/ROUTER (5661/5662), event-bus XPUB/XSUB (5663/5664), raw-inference PUSH/PULL (5665/5666), control ROUTER/DEALER (5667), credit-return router (5668), credit-return PUSH/PULL fan-in (5669). Kubernetes runs the dual-bind backend, so the authoritative defaults are `src/aiperf/config/comm/dual_bind.py:241-291`; the event-bus pair is bound by the proxy sidecar from `src/aiperf/kubernetes/environment.py:216-229`. |
+| All benchmark pods | Controller pod | 8080-8088 (TCP) | Health and readiness probes (`src/aiperf/kubernetes/environment.py:180-215`) |
+| Client / ingress | API service | 9090 (TCP) | UI dispatch, progress streaming (`environment.py:195-197`) |
+| Client / ingress | Results sidecar | 9091 (TCP) | Post-run result downloads (`environment.py:198-203`) |
+| Controller + worker pods | LLM inference endpoint | 443 (TCP) | Outbound HTTPS to the endpoint under benchmark |
+| All benchmark pods | `kube-dns` (UDP 53) | 53 | Pod DNS lookups for headless Service peer discovery |
+| Operator pod | Kube API server | 443/6443 (TCP) | Watch CRDs, create JobSets, patch status |
+
+Sample allow-list in the benchmark namespace:
+
+```yaml
+apiVersion: networking.k8s.io/v1
+kind: NetworkPolicy
+metadata:
+  name: aiperf-benchmark-allow
+  namespace: my-benchmarks
+spec:
+  podSelector:
+    matchLabels:
+      app.kubernetes.io/name: aiperf
+  policyTypes: [Ingress, Egress]
+  ingress:
+  - from:
+    - podSelector:

+    ports:
+    - {protocol: UDP, port: 53}
+  - to: []
+    ports:
+    - {protocol: TCP, port: 443}
+```
+
+The final egress rule to `0.0.0.0/0:443` is the LLM endpoint reach; lock
+it down to the endpoint's `Service`/`Endpoints` selector or an
+`ipBlock.cidr` matching your inference gateway when the target is on-cluster.
+
+### Operator NetworkPolicy
+
+`deploy/helm/aiperf-operator/templates/networkpolicy.yaml` ships an opt-in
+policy that locks down the **operator pod** (not the benchmark pods).
+Enable with `networkPolicy.enabled=true`. The rendered policy:
+
+- **Ingress** — allows TCP 8080 (operator health), TCP
+  `resultsServer.port` (default 8081), and TCP `operator.metrics.port`
+  (default 9090, omitted when set to 0) from four namespace selectors: the
+  release namespace itself (so `helm test` hook pods can reach `/healthz`),
+  every entry in `benchmarkRbacNamespaces`, and every entry in
+  `networkPolicy.allowedNamespaces`. CIDR blocks in
+  `networkPolicy.allowedIngressCIDRs` are added as a second ingress rule
+  for external scrapers (e.g. Prometheus, ingress controllers) on the same
+  ports.
+- **Egress** — allows DNS (UDP/TCP 53 to `kube-system`), the Kubernetes
+  API server (TCP 443 and 6443, no selector), and full egress to the release
+  namespace plus any `benchmarkRbacNamespaces` and `allowedNamespaces`
+  entries.
+
+Pair this with a default-deny in the operator namespace so only these
+flows are permitted. The policy's `podSelector` targets the operator
+Deployment labels (`aiperf-operator.operatorSelectorLabels`), so other
+workloads in the namespace are unaffected.
+
+### Ingress
+
+`deploy/helm/aiperf-operator/templates/ingress.yaml` ships an opt-in
+`Ingress` that exposes the operator's **results-server** (the FastAPI app on
+`resultsServer.port`, default 8081) outside the cluster. Disabled by
+default — results are reachable via ClusterIP + `kubectl port-forward` or
+the `aiperf kube` CLI. Enable with `ingress.enabled=true`.
+
+Security implications:
+
+- **TLS** — set `ingress.tls` to a list of `{hosts, secretName}` entries;
+  the chart threads them straight into the Ingress `spec.tls`. Without
+  this, traffic to the results server transits the ingress controller as
+  plain HTTP.
+- **Annotations** — `ingress.annotations` is passed through verbatim. Use
+  it to wire ingress-controller-specific auth (e.g. `nginx.ingress.kubernetes.io/auth-*`,
+  OIDC annotations), rate limits, and WAF rules. The results server itself
+  has no built-in authentication; if the Ingress is reachable from
+  untrusted networks, front it with auth at the controller layer.
+- **IngressClass** — set `ingress.className` to pin the controller (e.g.
+  `nginx`, `traefik`); empty uses the cluster default. Mis-pinning to a
+  public-facing class when you meant internal-only is the most common
+  misconfiguration.
+- **Backend** — each path's default backend port is
+  `resultsServer.port`; override per-path with `portNumber` if you fan
+  multiple services behind a single host. Nothing routes the kopf liveness
+  endpoint (8080) or the metrics port (9090) by default, so they stay
+  reachable only through the ClusterIP Service. Do not point a `portNumber`
+  at either one.
+
+Pair with `networkPolicy.enabled=true` (see above) so only the Ingress
+controller's namespace can reach the operator pod on the results port.
+
+## Least-privilege recipe
+
+A hardened rollout checklist:
+
+1. **Pre-provision operator RBAC** — apply the `ServiceAccount`,
+   `ClusterRole`, and `ClusterRoleBinding` under admin review. Install the
+   chart with `rbac.create=false` and `serviceAccount.create=false`, and pass
+   `serviceAccount.name` naming the account you created — the chart rejects
+   `serviceAccount.create=false` without it.
+2. **Dedicated benchmark namespace per team** — never share the benchmark
+   namespace between teams. Benchmark pods have read access to every pod
+   in the namespace (`benchmark-rbac.yaml:19-21`), so coexisting unrelated
+   workloads leak metadata. The operator-created per-job Role widens the read
+   surface further: pods can also list `configmaps`, `services`, `endpoints`,
+   `events`, and `jobsets` anywhere in the namespace. It grants no write verb
+   beyond `patch` on the pod's own AIPerfJob and JobSet.
+3. **Distinct ServiceAccounts per namespace** — the chart's benchmark
+   `RoleBinding` hardcodes `default` and exposes no values key to change it.
+   To avoid granting the namespace's `default` SA anything, create your own
+   SA (e.g. `aiperf-benchmark-sa`) and set
+   `spec.podTemplate.serviceAccountName` on the AIPerfJob. The operator's
+   per-job `RoleBinding` follows that field, so the pods still get the
+   permissions they need without the chart Role applying to `default`.
+4. **`runAsNonRoot: true` everywhere** — the base context already enforces
+   this, and `runAsUser: 0` / `runAsNonRoot: false` overrides are rejected
+   rather than honored. Nothing to configure.
+5. **`readOnlyRootFilesystem: true`** — keep the default; cover the five
+   writable paths above with `emptyDir` volumes.
+6. **Drop all Linux capabilities** — the base context drops `ALL`. If a
+   sidecar demands `NET_BIND_SERVICE` for a low port, add via
+   `containerSecurityContext.capabilities.add` rather than reverting the
+   drop. Note that `capabilities.add` is not on the rejected-override list,
+   so this field is the one remaining way a CR author can widen the
+   container's capability set; step 12 is what actually bounds it.
+7. **`seccompProfile: RuntimeDefault`** — default-applied. Do not downgrade
+   to `Unconfined`.
+8. **NetworkPolicy default-deny + allow-list** — apply the sample above
+   and lock the LLM endpoint egress to a CIDR or selector.
+9. **ResourceQuota on the benchmark namespace** — AIPerf preflight reads
+   quotas (`clusterrole.yaml`) and projects the run's CPU and memory
+   against them. Insufficient headroom is reported as a warning, not a
+   failure, so gate on it yourself with `aiperf kube preflight -o json` if
+   CI must stop there.
+10. **Audit logging** — enable Kubernetes audit logging on the
+    `aiperf.nvidia.com` and `jobset.x-k8s.io` API groups. Operator
+    reconciliation events, including status patches and JobSet creation,
+    appear under the operator SA and are easy to attribute.
+11. **Image pull secrets** — reference secrets via `imagePullSecrets` in
+    `values.yaml` rather than mounting credentials into pods.
+12. **PodSecurity admission** — enforce the `restricted` profile on the
+    benchmark namespace. AIPerf's default container `securityContext`
+    already satisfies it.
+
+With this profile, a compromised benchmark pod cannot escape its namespace,
+cannot read cluster-wide resources, cannot read Secrets, cannot write outside
+its emptyDir volumes (unless the CR author added a writable `hostPath` or other
+host-backed volume — see "Unhardened passthroughs" above), cannot escalate privilege or run as root, cannot create,
+replace, or delete any Kubernetes object, and can only reach the LLM endpoint and
+its own peers. Two capabilities remain inside the namespace: it can read the
+metadata of every pod, ConfigMap, Service, Endpoint, Event, and Job there, and it
+can `patch` annotations and `status` on its own AIPerfJob and JobSet — enough to
+report a false phase or a premature completion for its own run, not enough to
+affect another job. Namespace-per-team is still the boundary that matters.

+# Results Server API
+
+The AIPerf operator ships a standalone HTTP server (the **results server**) as a sidecar inside the operator pod. It exposes a catalog of `/api/v1/...` endpoints for listing jobs, downloading raw result files, querying the SQLite-backed runs index for analytics, and introspecting live AIPerfJob state.
+
+This reference documents the primary endpoints served by that process; it is not exhaustive. The results server also mounts a **sweeps** router (`/api/v1/sweeps/...` — list, create, detail, cells, children, epochs, config, events, logs, artifacts), a **config** router (`/api/v1/config/retention`, `/api/v1/config/features`), a **validate** router (`POST /api/v1/validate`), additional per-job routes (`/api/v1/jobs/{ns}/{name}/epochs|events|logs`, zip and per-epoch result downloads), and an admin `/admin/index/run/{ns}/{job_id}` index-row route. The source of truth is `src/aiperf/operator/results_server.py` and the routers under `src/aiperf/operator/routers/`.
+
+---
+
+## How to reach the API
+
+The results server listens on `resultsServer.port` (default **`8081`**) inside the operator pod. Helm injects this as `AIPERF_RESULTS_SERVER_PORT`, which the server validates as an integer from 1 through 65535. It is fronted by the operator's Service, not exposed externally by default. Two common access patterns:
+
+### Port-forward via the CLI
+
+```bash
+aiperf kube dashboard
+```
+
+This opens the browser UI and port-forwards the results server to an ephemeral local port. Pass `--no-browser` to just print the URL, or `--port 8081` to pin a specific local port. The port-forward stays open until Ctrl+C.
+
+### Direct `kubectl port-forward`
+
+```bash
+kubectl -n aiperf-system port-forward svc/aiperf-operator 8081:8081
+```
+
+The base URL is then `http://localhost:8081`, and all endpoints below are reachable at `http://localhost:8081/api/v1/...`.
+
+### Request topology
+
+```mermaid
+flowchart LR
+    client[CI / browser / script] -->|HTTP :8081| svc[Service<br/>aiperf-operator]
+    svc --> sidecar[results-server<br/>container]
+    sidecar --> pvc[(Results PVC)]
+    sidecar --> idx[(runs index<br/>SQLite)]
+    sidecar -->|kubernetes_asyncio| kubeapi[Kubernetes API]
+    idx --> pvc
+```
+
+The sidecar reads result files from the shared PVC and queries the Kubernetes API (via in-cluster RBAC) for live job/cluster state. Read-only routes have no per-request authentication layer; mutating routes are disabled by default and require explicit bearer-token configuration when enabled. See [Auth / security](#auth--security).

+| GET | `/dashboard/{path}` | dashboard-proxy | aiohttp reverse-proxy to the optional Plotly Dash sidecar (returns `503` when the sidecar is disabled or unreachable) |
+
+Final artifacts are **run-scoped, not job-scoped**: the three job-scoped
+`/api/v1/results/{namespace}/{job_id}[.zip|/{filename}]` routes exist only to
+reject with `409` and point the caller at `/runs/<epoch>/...`. This keeps a
+caller from pairing a live job status with whichever run `latest.txt` happened
+to point at mid-request.
+
+The per-run file-list response includes `per_record_filename` and
+`server_metrics_filename` when those artifacts are present. Clients should use
+these fields rather than assuming the default filenames: `artifacts.prefix`
+changes both names for that particular run.
+
+`GET /api/v1/jobs` and `GET /api/v1/jobs/{namespace}/{name}` are served through
+an ETag helper: they set `ETag` plus `Cache-Control: no-cache` and answer a
+matching `If-None-Match` with `304 Not Modified`, so a polling client pays only
+the hash on an unchanged job list.
+
+---
+
+## Meta
+
+### `GET /healthz`
+
+Liveness probe. Always returns `200 OK`.
+
+```bash
+curl http://localhost:8081/healthz
+```
+
+```json
+{"status": "ok"}
+```
+
+### `POST /api/v1/validate`
+
+Dry-run validation of an AIPerfJob or AIPerfSweep manifest. Nothing is created and no cluster access is required, so this route is not behind the mutating-route token.
+
+**Request body**
+
+| Field | Type | Default | Description |
+|-------|------|---------|-------------|
+| `manifest` | object | required | Full AIPerfJob or AIPerfSweep manifest dict |
+| `strict` | bool | `false` | Treat unknown spec fields as errors rather than warnings |
+
+Unknown top-level body fields are rejected (`extra="forbid"` → `422`).
+
+```bash
+curl -X POST http://localhost:8081/api/v1/validate \
+  -H 'Content-Type: application/json' \
+  -d '{"manifest": {"apiVersion": "aiperf.nvidia.com/v1alpha1", "kind": "AIPerfJob", "spec": {}}}'
+```
+
+```json
+{
+  "passed": false,
+  "errors": ["spec.benchmark: field required"],
+  "warnings": []
+}
+```
+
+Because the route is unauthenticated and exists purely to convert a bad manifest
+into a structured verdict, a well-formed request body always answers `200 OK`
+with this shape — never `500`. A validator that raises unexpectedly is caught,
+logged server-side, and reported as `passed: false` with a single
+`Validation aborted: <ExceptionType>: <message>` entry in `errors`. Only a
+malformed *request body* (bad JSON, missing `manifest`, unknown top-level field)
+produces a non-`200`, as `422`.
+
+---
+
+## Jobs
+
+Live state read directly from the Kubernetes API. Every endpoint in this section returns `503 Service Unavailable` if the results server could not initialize its Kubernetes client at startup (e.g. no kubeconfig and not running in-cluster).
+
+The one exception is `GET /api/v1/jobs/{namespace}/{name}/epochs`, which takes the API client as *optional*: without a cluster connection it still serves the PVC-derived epoch list, just with `status` left at `"unknown"` for epochs the runs index has not ingested.
+
+### `GET /api/v1/jobs`
+
+List every known AIPerfJob across all namespaces.
+
+**The response is a union**, not just live CRs: `job_union.list_all_jobs` merges live AIPerfJob CRs (`source: "live"`), PVC-only historical runs whose CRs were garbage-collected (`source: "archived"`), and runs present in both (`source: "both"`). Entries are keyed by `(namespace, name)`; overlaps prefer CR values on live fields and backfill historical fields from the PVC.
+
+```bash
+curl http://localhost:8081/api/v1/jobs
+```
+
+```json
+{
+  "jobs": [
+    {
+      "name": "aiperf-bench-7f2a",
+      "namespace": "my-benchmarks",
+      "phase": "Running",
+      "jobId": "aiperf-bench-7f2a",
+      "created": "2026-04-22T14:08:11Z",
+      "source": "live"
+    }
+  ]
+}
+```
+
+`AIPerfJobInfo` (`kubernetes/models.py`) is a camelCase-aliased model, so live
+metric fields serialize as `throughputRps`, `latencyP99Ms`, `ttftMs`,
+`outputTokenThroughputTps`, `interTokenLatencyMs`, `progressPercent`,
+`totalRequests`, `errorRate`, and the sweep-child fields as `sweepName`,
+`variationIndex`, `variationLabel`, `variationValues`, `trialIndex`. All are
+optional and serialize as `null` when the CR status has not reported them.
+
+**Status codes**
+
+- `200` — success (possibly empty list)
+- `304` — `If-None-Match` matched the current ETag
+- `401` / `403` — surfaced verbatim if the sidecar's ServiceAccount lacks RBAC to list `aiperfjobs.aiperf.nvidia.com`
+- `503` — Kubernetes client unavailable
+
+### `GET /api/v1/jobs/{namespace}/{name}`
+
+Fetch a single AIPerfJob CR plus its pod roster. Accepts an optional `?epoch=` query parameter to pin the archived half to a specific historical run directory instead of following `latest.txt`.
+
+Archived (PVC-only) jobs have no cluster CR, so the response carries the archived summary with an empty `status` object and an empty `pods` list.
+
+**Path parameters**
+
+| Name | Type | Description |
+|------|------|-------------|
+| `namespace` | string | Kubernetes namespace of the AIPerfJob CR |
+| `name` | string | AIPerfJob CR name |
+
+```bash
+curl http://localhost:8081/api/v1/jobs/my-benchmarks/aiperf-bench-7f2a
+```
+
+```json
+{
+  "job": {
+    "name": "aiperf-bench-7f2a",
+    "namespace": "my-benchmarks",
+    "phase": "Running"
+  },
+  "status": {
+    "phase": "Running",
+    "conditions": [],
+    "liveMetrics": {"requestThroughput": 1842.3}
+  },
+  "pods": [
+    {"name": "aiperf-bench-7f2a-controller-0", "phase": "Running", "ready": true, "restarts": 0, "containers": ["controller"]},
+    {"name": "aiperf-bench-7f2a-worker-0",     "phase": "Running", "ready": true, "restarts": 0, "containers": ["worker"]}
+  ]
+}
+```
+
+Pods are filtered by the label selector `aiperf.nvidia.com/job-id=<name>`. Each entry's `containers` list is the pod spec's container names in spec order — those are exactly the accepted values for `?container=` on the logs endpoint.
+
+**Status codes**
+
+- `200` — success
+- `304` — `If-None-Match` matched the current ETag
+- `400` — `namespace` or `name` is not a valid RFC 1123 name (rejected before any path join), or `?epoch=` does not match the epoch allowlist
+- `404` — no AIPerfJob with that name in that namespace and no archived run on the PVC
+- `401` / `403` — RBAC denial
+- `503` — Kubernetes client unavailable
+
+### `POST /api/v1/jobs`
+
+Create an AIPerfJob CR from a manifest dict shaped exactly like `kubectl apply -f` input. Mutating route — see [Auth / security](#auth--security).
+
+**Request body**
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `manifest` | object | Full AIPerfJob manifest. `apiVersion` and `kind` are filled in when omitted; `metadata.namespace` defaults to `default`. |
+
+```bash
+curl -X POST \
+  -H "Authorization: Bearer ${AIPERF_OPERATOR_MUTATING_ROUTES_TOKEN}" \
+  -H 'Content-Type: application/json' \
+  -d @- http://localhost:8081/api/v1/jobs <<'EOF'
+{"manifest": {"metadata": {"name": "aiperf-bench-7f2a", "namespace": "my-benchmarks"}, "spec": {}}}

+  "name": "aiperf-bench-7f2a",
+  "uid": "9c1e6f3a-1c2b-4f4e-9a0f-7bb4a3d21b55"
+}
+```
+
+**Status codes**
+
+- `201` — CR created
+- `400` — manifest is not an object, `metadata` is not an object, or `metadata.name` is missing
+- `401` / `403` — mutating-route gate or RBAC denial
+- `409` — a CR with that name already exists in that namespace
+- `422` — apiserver rejected the manifest against the CRD schema
+- `503` — Kubernetes client unavailable
+
+### `POST /api/v1/jobs/{namespace}/{name}/cancel`
+
+Request cancellation of a running benchmark by patching the CR's `spec.cancel` to `true`.
+
+**This endpoint is asynchronous.** It returns immediately after the patch; the kopf operator observes the change and drives workers to a stopped state over the next several seconds. Poll `GET /api/v1/jobs/{namespace}/{name}` and wait for `status.phase` to become `Cancelled`, `Failed`, or `Succeeded` if you need to confirm termination.
+
+```bash
+curl -X POST \
+  -H "Authorization: Bearer ${AIPERF_OPERATOR_MUTATING_ROUTES_TOKEN}" \
+  http://localhost:8081/api/v1/jobs/my-benchmarks/aiperf-bench-7f2a/cancel
+```
+
+```json
+{"cancelled": true}
+```
+
+**Status codes**
+
+- `200` — patch submitted
+- `400` — the job is archived-only (PVC results exist but the CR is gone, so there is nothing to patch)
+- `404` — neither a live CR nor a PVC directory exists for that `namespace/name`
+- `401` / `403` — RBAC denial
+- `409` — concurrent-modification conflict (retry)
+- `503` — Kubernetes client unavailable
+
+### `GET /api/v1/cluster`
+
+Best-effort cluster-wide totals for the dashboard header.
+
+```bash
+curl http://localhost:8081/api/v1/cluster
+```
+
+```json
+{
+  "nodes": 12,
+  "gpus": 96,
+  "gpus_used": 40,
+  "gpus_free": 56,
+  "utilization_percent": 41.7,
+  "gpu_nodes": 8,
+  "nodes_free": 4,
+  "nodes_partial": 3,
+  "nodes_full": 1,
+  "kubernetes_version": "v1.29.4",
+  "cluster_name": "dgx-prod"
+}
+```
+
+`ClusterResponse` (`operator/routers/jobs_models.py`) carries the full GPU
+accounting (`gpus_used`/`gpus_free`/`utilization_percent`), GPU-node breakdown
+(`gpu_nodes`, `nodes_free`/`nodes_partial`/`nodes_full`), and an optional
+`cluster_name` in addition to the basic `nodes`/`gpus`/`kubernetes_version`.
+Both the node list and version query are best-effort: if RBAC is insufficient or the call fails, `kubernetes_version` is reported as `"unknown"` and counts fall back to `0`. The endpoint does not surface errors for these sub-queries.
+
+### `WS /api/v1/jobs/{namespace}/{name}/ws`
+
+Per-job WebSocket proxy. The browser dashboard's per-job detail page uses this to subscribe to the same realtime message stream the controller pod publishes (e.g. `realtime_metrics`, `credit_phase_progress`, `worker_group_stats`), so KPI tiles update at the controller's emit cadence (~1Hz) instead of the page's REST poll interval.
+
+The proxy is transparent: it does not subscribe on the client's behalf. After the WS opens, the browser sends the controller's standard subscribe frame:
+
+```json
+{"type": "subscribe", "message_types": ["realtime_metrics"]}
+```
+
+…and from then on receives upstream frames verbatim. Implementation: `src/aiperf/operator/routers/jobs_ws.py`.
+
+**Topology**
+
+```mermaid
+flowchart LR
+    browser[browser<br/>job-detail page] -->|WS /api/v1/jobs/{ns}/{name}/ws| op[operator<br/>results-server]
+    op -->|reads CR status.jobSetName| api[Kubernetes API]
+    op -->|WS controller-svc:API_SERVICE/ws| ctl[controller pod]
+```
+
+The operator looks up the AIPerfJob CR's `status.jobSetName`, derives the controller pod's headless-service DNS via `controller_dns_name(jobset_name, namespace)`, and opens an `aiohttp` WebSocket to `ws://<controller-dns>:<API_SERVICE>/ws`. Two `asyncio` pumps then bridge frames in both directions until either side closes.
+
+**Refusal close codes**
+
+The proxy refuses connections with private-use (`4xxx`) WebSocket close codes so the browser can distinguish causes:
+
+| Code | Meaning |
+|---:|---|
+| `4503` | Operator's Kubernetes API client is not yet initialized (lifespan startup race). Retrying after a moment is correct. |
+| `4404` | The CR has no `status.jobSetName` yet — either the job is still being created or it doesn't exist. The dashboard only opens this WS when `phase === 'running'`, so this should be rare. |
+| `4502` | Upstream WS to the controller pod failed (DNS, connection refused, timeout). Typically means the controller pod isn't running. |
+| `1000` | Normal close (either side hung up). |
+

+## Results (file serving)
+
+All file-serving endpoints read from the shared results PVC mounted at `AIPERF_RESULTS_DIR` (default `/data`). Files are laid out as `<namespace>/<job_id>/<epoch>/<filename>`, where `<epoch>` is a decimal-seconds run directory and a sibling `latest.txt` names the newest one.
+
+### `GET /api/v1/results`
+
+List every namespace/job directory with at least one stored file.
+
+```bash
+curl http://localhost:8081/api/v1/results
+```
+
+```json
+{
+  "jobs": [
+    {
+      "namespace": "my-benchmarks",
+      "job_id": "aiperf-bench-7f2a",
+      "file_count": 8,
+      "total_size_bytes": 24837211,
+      "model": "meta-llama/Llama-3.1-70B",
+      "endpoint": "http://llama:8000/v1/chat/completions"
+    }
+  ]
+}
+```
+
+`model` and `endpoint` are lifted from the run's persisted `job_spec.json` and are `null` when that file is missing or unreadable. Returns an empty `jobs` list (not a 404) if the PVC base directory doesn't exist yet.
+
+### `GET /api/v1/results/{namespace}/{job_id}/runs`
+
+List every stored run epoch for one job, newest first, with `latest_epoch` naming the current `latest.txt` target (`null` when the job has no runs yet).
+
+```bash
+curl http://localhost:8081/api/v1/results/my-benchmarks/aiperf-bench-7f2a/runs
+```
+
+### `GET /api/v1/results/{namespace}/{job_id}/runs/{epoch}`
+
+List all result files for one run epoch.
+
+```bash
+curl http://localhost:8081/api/v1/results/my-benchmarks/aiperf-bench-7f2a/runs/1777472025
+```
+
+```json
+{
+  "namespace": "my-benchmarks",
+  "job_id": "aiperf-bench-7f2a",
+  "ready": true,
+  "summary_available": true,
+  "per_record_filename": "profile_export.jsonl",
+  "server_metrics_filename": "server_metrics.json",
+  "files": [
+    {
+      "name": "profile_export_aiperf.csv",
+      "stored_name": "profile_export_aiperf.csv.zst",
+      "size_bytes": 381220,
+      "compressed": true,
+      "mtime_epoch": 1777472025
+    },
+    {
+      "name": "inputs.json",
+      "stored_name": "inputs.json",
+      "size_bytes": 4812,
+      "compressed": false,
+      "mtime_epoch": 1777472025
+    }
+  ]
+}
+```
+
+The `name` field is the **display name** (zstd suffix stripped); use it as the `{filename}` path parameter on the download endpoint. `stored_name` is the actual file on disk. `ready` reflects the sidecar's readiness marker; `summary_available` says whether the `profile_export` quick-export alias will resolve for this run.
+
+**Status codes**
+
+- `200` — success
+- `400` — `namespace` / `job_id` failed RFC 1123 path-parameter validation (this is how encoded traversal attempts are rejected)
+- `404` — no run directory `<namespace>/<job_id>/<epoch>/` exists
+- `422` — `{epoch}` does not match the epoch allowlist
+
+### `GET /api/v1/results/{namespace}/{job_id}/runs/{epoch}/{filename}`
+
+Download a single result file. The server handles content negotiation automatically based on `Accept-Encoding`.
+
+The lookup tries `<filename>.zst` first, then `<filename>` as-is. `namespace` and `job_id` are validated as RFC 1123 names before any path join (`400` on failure), and the resolved file path must stay under the run directory. Final artifacts are gated on the readiness marker: requesting one before the sidecar has written that marker returns `404` with a "Results not ready" message. Checkpoint artifacts are exempt from the gate, and the marker file itself is not downloadable.
+
+`{filename}` is a path-style parameter, so files inside the run's allowlisted subdirectories (e.g. checkpoints) are addressable with their relative path — exactly the `name` the listing endpoint returned.
+
+**Content negotiation for stored `.zst` files**
+
+| Client `Accept-Encoding` | Response `Content-Encoding` | Server action |
+|--------------------------|-----------------------------|---------------|
+| `zstd` (substring match) | `zstd` | Stream raw bytes unmodified |
+| `gzip` (no zstd)         | `gzip` | Decompress zstd, recompress as gzip on the fly |
+| anything else / absent   | absent | Decompress zstd to identity |
+
+**Content negotiation for stored raw files**
+
+The `common.compression.select_encoding` helper picks the best encoding the client accepts (default `IDENTITY`). `Content-Encoding` is set only if the server is recompressing; otherwise it's omitted.
+
+**Response headers (both paths)**
+
+- `Content-Disposition: attachment; filename="<display-name>"` (switched to the RFC 5987 `filename*=UTF-8''…` form for non-ASCII names)
+- `X-Filename: <display-name>`
+- `Cache-Control: no-store` and `Pragma: no-cache`
+- `Content-Type` derived from the display name's suffix: `text/csv`, `application/json`, `application/x-ndjson`, `application/vnd.apache.parquet`, `image/png`, else `application/octet-stream`
+
+```bash
+# Native zstd — smallest over the wire
+curl -H "Accept-Encoding: zstd" \

+```
+
+**Status codes**
+
+- `200` — stream begins (note: errors mid-stream surface as truncated bodies, not HTTP errors)
+- `400` — invalid `namespace` / `job_id` path parameter
+- `404` — run directory missing, results not yet marked ready, or neither `<filename>` nor `<filename>.zst` found
+- `422` — `{epoch}` does not match the epoch allowlist
+
+### `GET /api/v1/results/{namespace}/{job_id}/runs/{epoch}.zip`
+
+Stream the whole run epoch as a zip bundle, `Content-Disposition`-named after the run. Also gated on the readiness marker (`404` before it exists).
+
+### `GET /api/v1/results/{namespace}/{job_id}/runs/{epoch}/profile_export`
+
+Quick-export alias for that run's summary JSON, so a caller does not need to know whether the artifact prefix changed the filename. Takes one query parameter, `format`, constrained to `json` (it exists so csv/parquet shortcuts can be added without a new route).
+
+---
+
+## Analytics (runs-index backed)
+
+All analytics endpoints return `503` with message `"Analytics engine not initialized"` if the results-server lifespan hook has not yet populated the DB handle. The exception is `/analytics/scatter`, which checks `runs_index.is_open()` itself and returns an empty `entries` list rather than an error, so a cold dashboard renders an empty chart instead of a failure banner.
+
+Analytics leaderboard and history queries support the six indexed comparison metrics (`request_throughput`, `request_latency`, `time_to_first_token`, `output_token_throughput`, `output_token_throughput_per_user`, and `inter_token_latency`) and `avg`, `p50`, or `p99` statistics. Unsupported metric/stat combinations return an empty response without scanning artifact summaries.
+
+`/analytics/leaderboard`, `/history`, `/compare`, and `/summary` are backed by the `runs_index` SQLite store (`operator/runs_index.py`, exposed through the thin `ResultsDB` facade in `operator/results_db.py`) — flat-column SELECTs against indexed rows, with a zstd-compressed `metrics_json` blob for full-summary access. The cold-start cost (one PVC walk) moves to the operator's startup bootstrap; subsequent supported queries use the index and retain disk fallback + lazy backfill when the index is stale.
+
+### `GET /api/v1/analytics/leaderboard`
+
+Rank every run by a metric.
+
+**Query parameters**
+
+| Name | Type | Default | Description |
+|------|------|---------|-------------|
+| `metric` | string | `request_throughput` | Metric to rank by (e.g. `request_throughput`, `request_latency`) |
+| `stat` | string | `avg` | Statistic: `avg`, `p50`, or `p99` |
+| `order` | string | `desc` | Sort order (`asc` or `desc`) |
+| `limit` | int | `20` | Max results, `[1, 1000]` |
+| `epoch` | string? | `None` | Restrict to one run epoch; `None` = latest per `(namespace, job)` |
+
+```bash
+curl "http://localhost:8081/api/v1/analytics/leaderboard?metric=request_throughput&stat=avg&limit=5"
+```
+
+```json
+{
+  "metric": "request_throughput",
+  "stat": "avg",
+  "order": "desc",
+  "entries": [
+    {
+      "namespace": "my-benchmarks",
+      "job_id": "aiperf-bench-7f2a",
+      "epoch": "1777472025",
+      "value": 1842.3,
+      "unit": "requests/sec",
+      "start_time": "2026-04-22T14:08:11Z",
+      "end_time":   "2026-04-22T14:13:45Z",
+      "model": "meta-llama/Llama-3.1-70B",
+      "endpoint": "http://llama:8000/v1/chat/completions"
+    }
+  ]
+}
+```
+
+Every entry field except `namespace` and `job_id` is nullable. The dashboard's leaderboard page requests `limit=1000` and filters client-side, so a caller that relies on the `20` default will see a shorter list than the UI does.
+
+### `GET /api/v1/analytics/history`
+
+Return metric values over time, optionally filtered by model or endpoint.
+
+**Query parameters**
+
+| Name | Type | Default | Description |
+|------|------|---------|-------------|
+| `metric` | string | `request_throughput` | Metric to track |
+| `stat` | string | `avg` | Statistic: `avg`, `p50`, or `p99` |
+| `model` | string? | `None` | Filter by model name (substring match) |
+| `endpoint` | string? | `None` | Filter by endpoint URL (substring match) |
+| `namespace` | string? | `None` | Filter by Kubernetes namespace |
+| `limit` | int | `100` | Max results, `[1, 10000]` |
+| `epoch` | string? | `None` | Restrict to one run epoch; `None` = latest per `(namespace, job)` |
+
+```bash
+curl "http://localhost:8081/api/v1/analytics/history?metric=request_latency&stat=p99&model=Llama&limit=50"
+```
+
+```json
+{
+  "metric": "request_latency",
+  "stat": "p99",
+  "entries": [
+    {
+      "namespace": "my-benchmarks",
+      "job_id": "aiperf-bench-7f2a",
+      "epoch": "1777472025",
+      "value": 412.7,
+      "unit": "ms",
+      "start_time": "2026-04-22T14:08:11Z",
+      "model": "meta-llama/Llama-3.1-70B",
+      "endpoint": "http://llama:8000/v1/chat/completions"
+    }
+  ]
+}
+```
+
+`HistoryEntry` carries no `end_time` — that field exists only on the leaderboard rows.
+
+### `GET /api/v1/analytics/scatter`
+
+Return all four dashboard scatter metrics for every indexed run in a single SQLite query, replacing the N+1 leaderboard-plus-summary fan-out the dashboard used to issue. Takes no parameters.
+
+```bash
+curl http://localhost:8081/api/v1/analytics/scatter
+```
+
+```json
+{
+  "entries": [
+    {
+      "namespace": "my-benchmarks",
+      "job_id": "aiperf-bench-7f2a",
+      "epoch": "1777472025",
+      "model": "meta-llama/Llama-3.1-70B",
+      "request_throughput_avg": 1842.3,
+      "request_latency_p99": 412.7,
+      "time_to_first_token_avg": 38.1,
+      "output_token_throughput_avg": 21504.6
+    }
+  ]
+}
+```
+
+Entries are ordered newest epoch first. Every metric field is nullable. If the runs index is closed or the query raises, the endpoint returns `{"entries": []}` with `200` rather than an error.
+
+### `GET /api/v1/analytics/compare`
+
+Pull a side-by-side comparison of named jobs across a set of metrics. The response pivots the runs-index rows into `(metric, stat, unit, values={namespace/job_id: value})` entries for the UI.
+
+**Query parameters**
+
+| Name | Type | Default | Description |
+|------|------|---------|-------------|
+| `jobs` | list[string] | required | Repeat the parameter once per job ID |
+| `metrics` | list[string]? | `DEFAULT_COMPARE_METRICS` | Repeat the parameter; defaults to key performance metrics |
+| `epoch` | string? | `None` | Restrict every job to one run epoch; `None` = latest per job |
+
+```bash
+curl "http://localhost:8081/api/v1/analytics/compare?jobs=aiperf-bench-7f2a&jobs=aiperf-bench-9d4c&metrics=request_throughput&metrics=request_latency"
+```
+
+```json
+{
+  "job_ids": ["aiperf-bench-7f2a", "aiperf-bench-9d4c"],
+  "metrics": ["request_throughput", "request_latency"],
+  "entries": [
+    {
+      "metric": "request_throughput",
+      "stat": "avg",
+      "unit": "requests/sec",
+      "values": {
+        "my-benchmarks/aiperf-bench-7f2a": 1842.3,
+        "my-benchmarks/aiperf-bench-9d4c": 1790.8
+      }
+    }
+  ]
+}
+```
+
+For each metric, the server emits one entry per stat (`avg`, `p50`, `p99`), plus a `meta` block alongside `entries`. Entries where no job has a value are omitted. Value keys are `namespace/job_id` when a namespace is known, otherwise just the job ID.
+
+Passing a bare job name that matches runs in more than one namespace returns `409` with the ambiguous candidates listed; re-request using `namespace/job` syntax.
+
+### `GET /api/v1/analytics/summary/{namespace}/{job_id}`
+
+Return the full aggregated summary for one job (as a raw JSON object — no Pydantic schema because the shape is driven by the metrics plugin registry). Accepts an optional `?epoch=` query parameter; omitted, it follows `latest.txt`. Endpoint credentials in the embedded input config are redacted before the body is returned.
+
+```bash
+curl http://localhost:8081/api/v1/analytics/summary/my-benchmarks/aiperf-bench-7f2a
+```
+
+**Status codes**
+
+- `200` — summary found
+- `400` — `namespace` / `job_id` failed RFC 1123 path-parameter validation
+- `404` — no summary data for that `namespace/job_id`
+
+### `GET /api/v1/index`
+
+Return the full job index used for fast lookups, keyed by `<namespace>/<job_id>`. It is backed by the runs-index SQLite store via `get_db().index_entries()` (`operator/results_db.py` / `operator/runs_index.py`) — there is no `aiperf.operator.job_index` module. The shape is a dict of index rows consumed by the dashboard.
+
+```bash
+curl http://localhost:8081/api/v1/index
+```
+
+### `GET /api/v1/config/{namespace}/{job_id}`
+
+Return the original CR spec/config used to run a job. The server tries four sources in order (first hit wins) and records which one it used:
+
+1. **Index** (`source: "index"`) — fast path, served from the runs-index SQLite cache.
+2. **Standalone spec file** (`source: "file"`) — `<base>/<namespace>/<job_id>/job_spec.json` on the PVC.
+3. **Summary extraction** (`source: "summary"`) — pulls `input_config` out of the aggregated summary if the spec wasn't persisted separately.
+4. **Live CR** (`source: "cr"`) — fetches `spec` from the apiserver, covering running jobs whose artifacts haven't been persisted yet. Skipped entirely when `?epoch=` is set, since a pinned historical epoch must not be answered with the current CR.
+
+Specs from the first three sources are passed through `redact_endpoint_spec` (`aiperf.common.redact`) before being returned.
+
+Accepts an optional `?epoch=` query param (default: follow latest).
+
+```bash
+curl http://localhost:8081/api/v1/config/my-benchmarks/aiperf-bench-7f2a
+```
+
+```json
+{
+  "source": "file",
+  "spec": {
+    "benchmark": {
+      "model": ["meta-llama/Llama-3.1-70B"],
+      "endpoint": {"url": "http://llama:8000/v1/chat/completions"}
+    }
+  }
+}
+```
+
+**Status codes**
+
+- `200` — config found via one of the four sources
+- `400` — `namespace` / `job_id` failed RFC 1123 path-parameter validation
+- `404` — none of the sources had data for that `namespace/job_id`
+
+---
+
+## Auth / security
+
+Read-only results-server routes do not authenticate individual HTTP requests. Mutating routes are disabled by default and require an explicit bearer token when enabled.
+
+- **Mutating-route gate.** `POST /api/v1/jobs`, `POST /api/v1/jobs/{namespace}/{name}/cancel`, and `POST /api/v1/sweeps` return `403` unless `AIPERF_OPERATOR_MUTATING_ROUTES_ENABLED=true` is set on the results-server. When enabled, `AIPERF_OPERATOR_MUTATING_ROUTES_TOKEN` must also be set — an enabled-but-tokenless server also returns `403` — and callers must send `Authorization: Bearer <token>`; a missing, non-bearer, or mismatched credential returns `401`. The token comparison uses `secrets.compare_digest`. Note that `POST /admin/index/rebuild` is separately **disabled** on the results-server (`allow_rebuild=False`) and returns `503` regardless of the token — the index is rebuilt automatically at operator startup.
+- **Env var aliases.** `OperatorEnvironment` parses these settings at process startup. `AIPERF_OPERATOR_MUTATING_ROUTES_ENABLED` and `AIPERF_OPERATOR_MUTATING_ROUTES_TOKEN` are the preferred, higher-precedence aliases; `AIPERF_MUTATING_ROUTES_ENABLED` and `AIPERF_MUTATING_ROUTES_TOKEN` remain compatibility aliases. `routers/mutating_auth.py` consumes only the validated typed settings.
+- **Helm configuration.** The bundled chart does **not** template these variables — there is no `resultsServer.mutatingRoutes` value and no token-secret projection. Set `AIPERF_OPERATOR_MUTATING_ROUTES_ENABLED` and `AIPERF_OPERATOR_MUTATING_ROUTES_TOKEN` directly on the `results-server` container (e.g. via a deployment patch or a customized chart template).
+- **First-party callers.** Clients must send the configured token as `Authorization: Bearer <token>` on protected POST requests. Note the rebuild route is mounted with `allow_rebuild=False` on the results-server and always returns `503`; only a fresh bootstrap in the operator's writer process rebuilds the index, so restart the operator pod instead. The browser dashboard *does* expose create/cancel controls: it prompts for the bearer token, holds it in `sessionStorage` for the tab's lifetime, and sends it on those POSTs (`ui/lib/api.js` `mutatingFetch`, `ui/components/token-modal.js`). A `401` clears the stored token and re-prompts. `aiperf kube` and `kubectl` remain the token-free paths, since they talk to the apiserver directly rather than through the results-server.
+- **In-cluster RBAC.** The sidecar uses its ServiceAccount token to call the Kubernetes API. Every `/api/v1/jobs/*` and `/api/v1/cluster` call runs with those permissions, so `list aiperfjobs`, `get pods`, `patch aiperfjobs/spec`, and `list nodes` must be granted in the operator's ClusterRole. RBAC failures surface as `401` / `403` propagated from `kubernetes_asyncio`.
+- **Network isolation.** The Service is typically `ClusterIP` only. External access is expected to come via `kubectl port-forward` (trusted user), `aiperf kube dashboard` (trusted user), or an ingress controller. Add a `NetworkPolicy` if your cluster requires stricter pod-to-pod controls.
+- **Path traversal.** File-serving endpoints resolve every `{namespace}/{job_id}/{filename}` under the results directory and reject resolved paths that escape the base (`404`). Callers cannot read files outside the PVC.
+
+Do **not** expose the results server directly to the public internet without a proxy that enforces authentication in front of the read-only routes too.

+# Controller Pod Sidecars
+
+> **Scope:** **controller-pod** sidecars only — the event-bus proxy and the
+> results sidecar that ride alongside the SystemController. The operator
+> Pod's `results-server` container (port 8081) is also colloquially called
+> a sidecar; that one hosts the operator's HTTP API and is documented in
+> [`docs/kubernetes/results-api.md`](results-api.md) and
+> [`docs/dev/kubernetes-flow.md`](../dev/kubernetes-flow.md). Don't confuse

+> sweep-controller's empty-summary fallback both target the **operator**'s
+> results-server, never the controller's `results-sidecar`.
+
+Every AIPerf benchmark controller pod runs a short stack of sidecar containers alongside the control-plane process. Two of them — the **event-bus proxy** and the **results sidecar** — exist to offload load or provide a fallback surface that the SystemController itself cannot reliably host. They are invisible in normal usage, but anyone debugging fan-in hangs, startup races, or partial result retrieval needs to know what they do and how to tune them.
+
+The source of truth is `src/aiperf/kubernetes/jobset.py` (composition), `src/aiperf/kubernetes/results_sidecar.py` (FastAPI app), and `src/aiperf/kubernetes/environment.py` (resource defaults and ports).
+
+---
+
+## Overview
+
+**Event-bus proxy** runs the XPUB/XSUB ZMQ proxy for the benchmark's pub/sub event bus in a dedicated container. It exposes `tcp://*:5663` (XSUB frontend — publishers connect here) and `tcp://*:5664` (XPUB backend — subscribers connect here) on the controller pod so that workers and record processors can connect and publish/subscribe without talking to the SystemController directly. It is an independent sidecar because, at high concurrency, hundreds of simultaneous RP and worker pub/sub connections arriving at pod startup previously starved the SystemController's event loop while it tried to forward socket I/O itself. Health endpoint is `:8088/healthz` and `:8088/readyz`.
+
+**Results sidecar** runs a minimal FastAPI app on `:9091` that serves the controller pod's `/results` volume read-only. It exists as a fallback so the **operator's** completion fetch can still retrieve exported artifacts after the main control-plane container exits — for example, when the controller completes exports and terminates but the JobSet TTL hasn't cleaned the pod up yet. (`aiperf kube results --from-pods` does not use it; see [When the results sidecar is used](#when-the-results-sidecar-is-used).) Non-checkpoint files are hidden until the controller writes the `.aiperf_results_ready.json` marker on clean exit, so clients never download half-written artifacts.
+
+Both sidecars are always injected into controller pods by default. Disabling them is almost never correct.

+| CPU request + limit  | 50m     | `AIPERF_K8S_EVENT_BUS_PROXY_CPU`       |
+| Memory request + limit | 64Mi  | `AIPERF_K8S_EVENT_BUS_PROXY_MEMORY`    |
+
+Both values are set as request *and* limit, so the container lands in the Guaranteed QoS class. The default is small because the proxy is pure socket I/O forwarding. Isolating it in its own container (rather than in the SystemController event loop) keeps large startup fan-ins — hundreds of simultaneous record-processor and worker connections — from starving the control plane's event loop while it forwards socket I/O itself. If you observe the proxy pegging its core at very large fan-ins, raise `AIPERF_K8S_EVENT_BUS_PROXY_CPU`.
+
+### Startup ordering
+
+The proxy container is prepended to the controller pod's container list (`create_controller_containers` inserts it at index 0), so the kubelet begins pulling and starting it before the control-plane container. The proxy's bind sockets come up in tens of milliseconds — well inside the client connection-probe timeout, which is 90 s by default (`AIPERF_SERVICE_CONNECTION_PROBE_TIMEOUT`) and 60 s for k8s worker containers specifically (`AIPERF_K8S_JOBSET_WORKER_CONNECTION_PROBE_TIMEOUT`).
+
+### Disabling (legacy fallback)
+
+Set on the operator deployment:
+
+```bash
+AIPERF_K8S_EVENT_BUS_SIDECAR_ENABLED=false
+```
+
+This reverts to pre-sidecar behavior: the SystemController's `ProxyManager` hosts the XPUB/XSUB proxy inside its own event loop. This is a legacy code path kept only for bisecting regressions — do not run production benchmarks with it disabled. At large fan-ins it will reintroduce the startup stall that motivated the sidecar in the first place.
+
+---
+
+## Results sidecar
+
+The results sidecar is a small FastAPI app launched via `python -m aiperf.kubernetes.results_sidecar`. It mounts the controller pod's shared `/results` volume — an `emptyDir`, so it lives and dies with the pod — read-only, and exposes three endpoints on port **9091**.
+
+### Endpoint catalog
+
+| Method | Path                              | Purpose                                        |
+|--------|-----------------------------------|------------------------------------------------|
+| GET    | `/healthz`                        | Liveness probe. Always `200 OK`.               |
+| GET    | `/api/results/list`               | List available result files (JSON)             |
+| GET    | `/api/results/files/{filename}`   | Download a result file (with content negotiation) |
+
+The response models (`ResultFileInfo`, `ResultsListResponse`) live in `src/aiperf/api/models/results.py` and are shared with the in-process controller API router (`src/aiperf/api/routers/results.py`), so the two HTTP surfaces are schema-identical. Their listing behavior differs in one respect: the sidecar walks `/results` recursively once the ready marker exists, while the controller router lists only top-level files (plus a recursive walk of `checkpoints/`).
+
+### `GET /healthz`
+
+```bash
+curl http://localhost:9091/healthz
+# {"status":"ok"}
+```
+
+### `GET /api/results/list`
+
+Returns the JSON body defined by `ResultsListResponse`. Names are paths
+relative to `/results` (the walk is recursive, so nested sweep-harvest
+layouts surface too), and the response also carries the two readiness flags:
+
+```json
+{
+  "files": [
+    {"name": "checkpoints/phase_0.parquet", "size": 1048576},
+    {"name": "metrics.json",                "size": 41820},
+    {"name": "profile_export_aiperf.json",  "size": 18331144},
+    {"name": "profile_export_console.txt",  "size": 3402}
+  ],
+  "ready": true,
+  "processing": false
+}
+```
+
+Readiness semantics:
+
+- If `.aiperf_results_ready.json` exists, every file under `/results` is listed recursively (both transaction markers are excluded — `.aiperf_results_ready.json` and `.aiperf_results_processing.json` are sidecar-internal state, not artifacts).
+- If the marker is absent, only files under `/results/checkpoints/` are listed. Everything else is hidden until the controller finishes cleanly.
+- `processing` reflects the separate `.aiperf_results_processing.json` marker written while the controller is still exporting.
+
+### `GET /api/results/files/{filename}`
+
+Streams a single file. Honors `Accept-Encoding` — if the client advertises `zstd` or `gzip`, the sidecar streams the compressed body and sets `Content-Encoding` accordingly (via `aiperf.common.compression.stream_file_compressed`). Otherwise the file is returned as-is.
+
+- Sets `Content-Disposition: attachment; filename="..."` and `X-Filename` headers.
+- `Content-Type` is inferred from the extension: `.json`, `.jsonl`, `.csv`, `.parquet`, `.txt`; everything else is `application/octet-stream`.
+
+Error semantics:
+
+| Status | When                                                                          |
+|--------|-------------------------------------------------------------------------------|
+| 400    | Path traversal (`..`, symlink escaping `/results`) or a reserved marker name  |
+| 404    | Controller not ready (marker absent) and file is not under `checkpoints/`     |
+| 404    | File path resolves correctly but does not exist                               |
+
+### Path safety
+
+`_safe_resolve` resolves the requested filename under the base directory and rejects anything that, after resolution, does not sit inside `base_dir.resolve()`. This catches `..`, absolute paths, and symlinks that would escape `/results`. Both transaction markers (`.aiperf_results_ready.json`, `.aiperf_results_processing.json`) are explicitly unfetchable.
+
+### Readiness marker
+
+The controller writes `/results/.aiperf_results_ready.json` via `write_ready_marker()` at the end of `SystemController` shutdown, once all exporters have flushed. The payload records whether the run was cancelled:
+
+```json
+{"ready": true, "was_cancelled": false}
+```
+
+`terminal_phase` and `terminal_error` keys are added only when the caller supplies them.
+
+Until the marker exists, the sidecar returns 404 on any top-level file. Checkpoint artifacts under `/results/checkpoints/` are served unconditionally so that in-flight progress can be inspected mid-run.
+
+---
+
+## When the results sidecar is used
+
+The results sidecar is reached by the operator, not directly by `aiperf kube results --from-pods`:
+
+1. **`aiperf kube results --from-pods`** never targets `:9091`. On the default `--all` path it uses only the **Controller API** (`http://controller-pod:9090/api/results/files/...`) via port-forward. The second tier — **`kubectl cp`** against the `control-plane` container's `/results` directory — is reached only on the `--summary-only` path, when the API call fails first. Both tiers require the control-plane container to still be running.
+2. **Operator completion fetch** reaches the results sidecar directly via `_download_final_and_sidecar` in `src/aiperf/operator/handlers/_completion_fetch.py`. When the primary client returns without the key result files, the operator re-issues the download against the sidecar port (`:9091`). Because the sidecar outlives the control-plane container, it covers the window between export completion and pod deletion.
+
+If neither path returns the files, results can only be recovered from operator-side storage (see `aiperf kube results` without `--from-pods`).
+
+---

+| `AIPERF_K8S_EVENT_BUS_SIDECAR_ENABLED` | `true`  | `false` only for bisecting regressions against the pre-sidecar code path  |
+
+### Results sidecar
+
+| Env var                              | Default | Notes                                                               |
+|--------------------------------------|---------|---------------------------------------------------------------------|
+| `AIPERF_K8S_RESULTS_SIDECAR_CPU`     | `25m`   | Adequate; streaming is compression-bound not CPU-bound              |
+| `AIPERF_K8S_RESULTS_SIDECAR_MEMORY`  | `192Mi` | Adequate                                                            |
+| `AIPERF_RESULTS_DIR`                 | `/results` | Volume mount path; set explicitly by the JobSet builder. Do not change unless you also remount the `results` volume |
+| `AIPERF_RESULTS_SIDECAR_PORT`        | `9091`  | Container port; set by the JobSet builder to match `PORTS.RESULTS_SIDECAR`. A malformed or out-of-range value is ignored with a warning and the sidecar falls back to `AIPERF_K8S_PORT_RESULTS_SIDECAR` rather than crash-looping |
+| `AIPERF_K8S_RESULTS_SIDECAR_LOG_LEVEL` | `info` | Operator-side setting. Allowed values: `critical`, `error`, `warning`, `info`, `debug`, `trace`. Injected into benchmark-controller and sweep-controller results sidecars as `AIPERF_RESULTS_SIDECAR_LOG_LEVEL` |
+| `AIPERF_RESULTS_SIDECAR_LOG_LEVEL` | `info` | Sidecar process-local input written by the operator; do not set directly in Kubernetes manifests. Validated against the same allowed values as the operator-side setting; anything else is ignored with a warning and falls back to `AIPERF_K8S_RESULTS_SIDECAR_LOG_LEVEL` |
+
+---
+
+## When to disable
+
+- **Event-bus proxy**: basically never. The pre-sidecar code path exists only as a bisection escape hatch and will reintroduce the SystemController startup starvation it was built to fix.
+- **Results sidecar**: always-on. There is no supported toggle to turn it off, because the operator's completion-fetch path depends on it when the control-plane container has already exited. If you want to skip artifact retrieval entirely, set `ttlSecondsAfterFinished: 0` on the AIPerfJob and let the JobSet delete the pod immediately.
+
+---
+
+## Troubleshooting
+
+### The `results-sidecar` container shows `Running` but `/api/results/list` returns only checkpoints (or 404 on key files)
+
+The controller has not finished exporting. The sidecar filters out top-level files until `.aiperf_results_ready.json` is written. This is expected while the run is still in progress — checkpoint artifacts will appear as they are written, but `metrics.json` and the profile exports only show up after a clean controller exit.
+
+If the controller has exited but the marker is still missing, the run was killed (OOM, SIGKILL, node eviction) before exporters flushed. Recover partial results by:
+
+1. Downloading `checkpoints/` via the sidecar — these are written incrementally.
+2. Falling back to `aiperf kube results` without `--from-pods` (operator-side storage, if the operator successfully fetched anything before termination).
+
+### `event-bus-proxy` is `CrashLoopBackOff`
+
+Check `aiperf kube logs <job> --container event-bus-proxy`. The two real failure modes:
+
+- `Address already in use` on 5663/5664 — something else is bound to those ports inside the pod; almost always a sign that the main control-plane container was started with the legacy in-process proxy (`AIPERF_K8S_EVENT_BUS_SIDECAR_ENABLED=false` on one side and `true` on the other). Align both.
+- Missing `run_config.json` — the ConfigMap didn't mount before the container started. `aiperf kube debug <job>` will show the volume error.
+
+### `/healthz` returns `200` but connections to `5663`/`5664` hang
+
+The proxy is up but has no subscribers yet. This is normal during pod startup before the control-plane container has registered as a subscriber on `tcp://127.0.0.1:5664`. If it persists well after the control-plane container reports `RUNNING`, inspect its logs for `ProxyManager` / `ZMQXPubXSubProxy` activity — the control-plane may be trying to run its own in-process proxy instead of connecting to the sidecar.

+# Deploy from a Source Checkout to a Real Kubernetes Cluster
+
+This guide starts from an AIPerf source checkout and deploys that code to a real Kubernetes cluster. It builds a container image, pushes it to a registry, installs or upgrades the AIPerf operator with Helm, then runs a benchmark against a real inference endpoint.
+
+This guide does **not** use the mock server path. Use it when you have a real OpenAI-compatible endpoint already running, or when you want to deploy a real Dynamo/vLLM endpoint first.
+
+## Prerequisites
+
+You need:
+
+- An AIPerf source checkout.
+- `kubectl` configured for the target cluster.
+- Helm v3.
+- Docker or another container builder that can build and push OCI images.
+- Registry credentials for the image repository you will use.
+- Permission to install CRDs, create the operator namespace, create benchmark namespaces, and create JobSet workloads.
+- JobSet installed on the cluster. If it is not installed, install it before the AIPerf operator.
+- A real OpenAI-compatible inference endpoint reachable from benchmark pods, or permission to deploy one.
+
+Check the cluster first:
+
+```bash
+kubectl cluster-info
+kubectl get nodes
+kubectl api-resources | grep -i jobset
+```
+
+For GPU benchmarks, verify GPU resources are allocatable:
+
+```bash
+kubectl get nodes -o custom-columns=NAME:.metadata.name,GPU:.status.allocatable.nvidia\.com/gpu
+```
+
+## 1. Set up the checkout
+
+Install the local development environment from the checkout:
+
+```bash
+make first-time-setup
+```
+
+Use the local CLI through `uv run` until the package is installed somewhere else:
+
+```bash
+uv run aiperf --help
+uv run aiperf kube --help
+```
+
+Pick a tag that identifies the exact checkout you are deploying:
+
+```bash
+export AIPERF_TAG="$(git rev-parse --short HEAD)"
+```
+
+## 2. Build and push the AIPerf image
+
+The same image is used by the operator containers and benchmark JobSet pods unless you explicitly override `defaults.image` in the Helm chart.
+
+### NGC-style registry
+
+Use this shape for an NGC organization or private NVIDIA registry namespace:
+
+```bash
+export AIPERF_IMAGE="nvcr.io/<org>/aiperf:${AIPERF_TAG}"
+
+docker build -t "${AIPERF_IMAGE}" .
+docker push "${AIPERF_IMAGE}"
+```
+
+### GitHub Container Registry
+
+Use this shape for GHCR:
+
+```bash
+export AIPERF_IMAGE="ghcr.io/<org>/aiperf:${AIPERF_TAG}"
+
+docker build -t "${AIPERF_IMAGE}" .
+docker push "${AIPERF_IMAGE}"
+```
+
+If your cluster nodes use a different architecture than the build host, build for the cluster platform:
+
+```bash
+docker buildx build \
+  --platform linux/amd64 \
+  -t "${AIPERF_IMAGE}" \
+  --push \
+  .
+```
+
+## 3. Create an image pull secret if the registry is private
+
+Skip this section if every node can pull the image without a secret.
+
+Create the operator namespace first:
+
+```bash
+kubectl create namespace aiperf-system --dry-run=client -o yaml | kubectl apply -f -
+```
+
+For NGC-style registries:
+
+```bash
+kubectl create secret docker-registry aiperf-registry \
+  --namespace aiperf-system \
+  --docker-server=nvcr.io \
+  --docker-username='$oauthtoken' \
+  --docker-password="${NGC_API_KEY}"
+```
+
+For GHCR:
+
+```bash
+kubectl create secret docker-registry aiperf-registry \
+  --namespace aiperf-system \
+  --docker-server=ghcr.io \
+  --docker-username="${GITHUB_USER}" \
+  --docker-password="${GITHUB_TOKEN}"
+```
+
+The Helm install below references this secret for the operator. Benchmark jobs also need pull access in the namespace you run them in. Kubernetes secrets are namespace-scoped, so create the same pull secret there:
+
+```bash
+kubectl create namespace <your-namespace> --dry-run=client -o yaml | kubectl apply -f -
+
+kubectl create secret docker-registry aiperf-registry \
+  --namespace <your-namespace> \
+  --docker-server=<registry-host> \
+  --docker-username=<username> \
+  --docker-password=<token>
+```
+
+## 4. Install or upgrade the AIPerf operator
+
+Split the image into repository and tag for Helm:
+
+```bash
+export AIPERF_IMAGE_REPOSITORY="${AIPERF_IMAGE%:*}"
+export AIPERF_IMAGE_TAG="${AIPERF_IMAGE##*:}"
+```
+
+Install the operator:
+
+```bash
+helm upgrade --install aiperf-operator deploy/helm/aiperf-operator \
+  --namespace aiperf-system \
+  --create-namespace \
+  --set image.repository="${AIPERF_IMAGE_REPOSITORY}" \
+  --set image.tag="${AIPERF_IMAGE_TAG}" \
+  --set image.pullPolicy=IfNotPresent
+```
+
+If you created `aiperf-registry`, include it in the Helm release:
+
+```bash
+helm upgrade --install aiperf-operator deploy/helm/aiperf-operator \
+  --namespace aiperf-system \
+  --create-namespace \
+  --set image.repository="${AIPERF_IMAGE_REPOSITORY}" \
+  --set image.tag="${AIPERF_IMAGE_TAG}" \
+  --set image.pullPolicy=IfNotPresent \
+  --set 'imagePullSecrets[0].name=aiperf-registry'
+```
+
+The chart default for `defaults.image` is empty, which means AIPerfJob pods use `<image.repository>:<image.tag>`, falling back to the chart's `appVersion` when `image.tag` is also empty. Set `defaults.image` only when benchmark pods should run a different image from the operator.
+
+Wait for the operator and results server:
+
+```bash
+kubectl rollout status deploy/aiperf-operator -n aiperf-system --timeout=180s
+kubectl get pods -n aiperf-system
+```
+
+Run Helm tests if the cluster can pull the chart's test image:
+
+```bash
+helm test aiperf-operator -n aiperf-system
+```
+
+## 5. Run against an existing real endpoint
+
+Use this path when your inference server is already deployed in the cluster or reachable from the cluster network.
+
+Set the endpoint and model:
+
+```bash
+export MODEL="Qwen/Qwen3-0.6B"
+export ENDPOINT_URL="http://vllm.default.svc.cluster.local:8000/v1"
+```
+
+Run cluster-side preflight checks:
+
+```bash
+uv run aiperf kube preflight \
+  --image "${AIPERF_IMAGE}" \
+  --endpoint-url "${ENDPOINT_URL}" \
+  --workers 8
+```
+
+Submit a benchmark:
+
+```bash
+uv run aiperf kube profile \
+  --model "${MODEL}" \
+  --url "${ENDPOINT_URL}" \
+  --image "${AIPERF_IMAGE}" \
+  --total-workers 8 \
+  --request-count 1000 \
+  --concurrency 50 \
+  --streaming
+```
+
+For private benchmark images, pass the pull secret name when submitting jobs:
+
+```bash
+uv run aiperf kube profile \
+  --model "${MODEL}" \
+  --url "${ENDPOINT_URL}" \
+  --image "${AIPERF_IMAGE}" \
+  --image-pull-secrets aiperf-registry \
+  --total-workers 8 \
+  --request-count 1000 \
+  --concurrency 50 \
+  --streaming
+```
+
+For repeatable runs, put the benchmark configuration in YAML and pass `--config benchmark.yaml`; see [End-to-End Workflow](workflow.md) for the `init` -> `validate` -> `preflight` -> `profile` sequence.
+
+## 6. Optional: deploy a real Dynamo/vLLM endpoint first
+
+Skip this section if you already have a real endpoint.
+
+Install the Dynamo platform chart if your cluster does not already have it:
+
+```bash
+helm upgrade --install dynamo-platform \
+  oci://nvcr.io/nvidia/ai-dynamo/dynamo-platform \
+  --version 1.1.0 \
+  --namespace dynamo-system \
+  --create-namespace \
+  --set dynamo-operator.webhook.enabled=false \
+  --set grove.enabled=false \
+  --set kai-scheduler.enabled=false
+```
+
+Deploy an aggregated Dynamo vLLM server by applying a `DynamoGraphDeployment` manifest such as the aggregated vLLM example in [Getting Started on Kubernetes](getting-started.md#step-2-deploy-a-dynamo-inference-server):
+
+```bash
+kubectl create namespace dynamo-server --dry-run=client -o yaml | kubectl apply -f -
+kubectl apply -f dynamo-server.yaml
+```
+
+Wait for the frontend and worker pods to become ready:
+
+```bash
+kubectl get pods -n dynamo-server -w
+```
+
+Use the Dynamo service URL as the benchmark endpoint:
+
+```bash
+export ENDPOINT_URL="http://dynamo-agg-frontend.dynamo-server.svc:8000/v1"
+
+uv run aiperf kube preflight \
+  --image "${AIPERF_IMAGE}" \
+  --endpoint-url "${ENDPOINT_URL}" \
+  --workers 8
+
+uv run aiperf kube profile \
+  --model "${MODEL}" \
+  --url "${ENDPOINT_URL}" \
+  --image "${AIPERF_IMAGE}" \
+  --total-workers 8 \
+  --request-count 1000 \
+  --concurrency 50 \
+  --streaming
+```
+
+## 7. Monitor and retrieve results
+
+Watch progress:
+
+```bash
+uv run aiperf kube list
+```
+
+Reattach to a detached run:
+
+```bash
+uv run aiperf kube attach
+```
+
+Download results:
+
+```bash
+uv run aiperf kube results --output ./aiperf-results
+```
+
+Port-forward the results server and dashboard:
+
+```bash
+kubectl port-forward -n aiperf-system svc/aiperf-operator 8081:8081
+```
+
+Then open `http://localhost:8081`.
+
+## 8. Upgrade after source changes
+
+After changing source code, repeat the build and push with a new immutable tag:
+
+```bash
+export AIPERF_TAG="$(git rev-parse --short HEAD)-$(date +%Y%m%d%H%M%S)"
+export AIPERF_IMAGE="nvcr.io/<org>/aiperf:${AIPERF_TAG}"
+
+docker build -t "${AIPERF_IMAGE}" .
+docker push "${AIPERF_IMAGE}"
+
+export AIPERF_IMAGE_REPOSITORY="${AIPERF_IMAGE%:*}"
+export AIPERF_IMAGE_TAG="${AIPERF_IMAGE##*:}"
+
+helm upgrade aiperf-operator deploy/helm/aiperf-operator \
+  --namespace aiperf-system \
+  --reuse-values \
+  --set image.repository="${AIPERF_IMAGE_REPOSITORY}" \
+  --set image.tag="${AIPERF_IMAGE_TAG}"
+```
+
+Wait for the new operator pod before submitting new jobs:
+
+```bash
+kubectl rollout status deploy/aiperf-operator -n aiperf-system --timeout=180s
+```
+
+## Troubleshooting
+
+### ImagePullBackOff
+
+Check the failing pod and events:
+
+```bash
+kubectl describe pod -n aiperf-system -l app.kubernetes.io/name=aiperf-operator
+uv run aiperf kube debug
+```
+
+Common fixes:
+
+- Confirm the image was pushed with the exact tag used by Helm or `aiperf kube profile`.
+- Create the pull secret in both `aiperf-system` and the benchmark namespace.
+- Pass `--image-pull-secrets aiperf-registry` to `aiperf kube profile` for private benchmark images.
+- Use `--set image.pullPolicy=Always` while testing mutable tags; prefer immutable tags for normal use.
+
+### Operator is running but jobs use an old image
+
+The operator image and default benchmark image come from the Helm release. Check the rendered CRD default:
+
+```bash
+kubectl get crd aiperfjobs.aiperf.nvidia.com \
+  -o jsonpath='{.spec.versions[?(@.name=="v1alpha1")].schema.openAPIV3Schema.properties.spec.properties.image.default}{"\n"}'
+```
+
+If you set `defaults.image`, it overrides the benchmark image independently of `image.repository` and `image.tag`.
+
+### Endpoint check fails
+
+Verify the endpoint from inside the cluster:
+
+```bash
+kubectl run curl-check \
+  --rm -it \
+  --restart=Never \
+  --image=curlimages/curl:latest \
+  -- curl -sf "${ENDPOINT_URL}/models"
+```
+
+If the server is still starting and you intentionally want the benchmark to wait until worker runtime, set `skipEndpointCheck: true` in the AIPerfJob YAML. Do not use this to hide a wrong service name or namespace.
+
+### RBAC or namespace errors
+
+The Helm chart creates benchmark RBAC in the release namespace and in any namespaces listed in `benchmarkRbacNamespaces`. If you run jobs in a different namespace, add that namespace to `benchmarkRbacNamespaces`:
+
+```bash
+helm upgrade aiperf-operator deploy/helm/aiperf-operator \

+# User-Defined Output Files (`artifacts.user_files`)
+
+`artifacts.user_files` lets you declare arbitrary templated output files that are
+materialized into the run directory before the benchmark begins. Files are rendered
+with jinja2 against the user `variables:` block plus a small set of system-injected
+names.
+
+`AIPerfJob` accepts the same block — `artifacts` is part of the shared
+`benchmark:` config envelope. `aiperf kube profile --config` serializes the spec
+with camelCase aliases before submitting it, so snake_case authoring in an AIPerf
+YAML is fine; in hand-written CR YAML use `artifacts.userFiles`, because the
+apiserver prunes keys the CRD schema does not advertise. `content` is a typeless
+`x-kubernetes-preserve-unknown-fields` node in both CRDs, so every legal shape —
+including a bare string for `format: text` — is accepted at admission, and the
+operator's Pydantic validators enforce the format/content pairing on reconcile.
+
+## Where the files are written
+
+The two execution paths reach the same result through different code:
+
+| Path | Who writes the files |
+|---|---|
+| Local (`aiperf profile`, local multi-run subprocess runner) | The config resolver chain (`ArtifactDirResolver`), which derives the render identity from the resolved artifact dir. |
+| Kubernetes (`AIPerfJob`, `AIPerfSweep` children) | The controller pod's `system_controller` container, before the benchmark starts, via `aiperf.kubernetes.user_files.materialize_serialized_run_user_files`. |
+
+Kubernetes service containers boot from the controller-rendered `BenchmarkRun`
+(`aiperf service --benchmark-run`) and deliberately skip the resolver chain, so
+that seeds, synthesized defaults, and artifact identity stay identical across
+pods. The declared entries therefore travel inside the serialized run itself and
+are rendered from that data — nothing is re-resolved in-pod. Only the
+`system_controller` container writes them: it owns the run directory that the
+results sidecar serves and the operator harvests, while worker pods mount their
+own private `/results` volume.
+
+> **Do not put secrets in `content`.** The serialized run is stored in a
+> Kubernetes ConfigMap, so anything you write into `content` is readable by any
+> principal with `get configmaps` in the benchmark namespace, and it is echoed
+> into the harvested artifacts. Pass credentials through
+> `podTemplate.envFromSecrets` instead; see
+> [Configuration](configuration.md).
+
+## Quickstart
+
+```yaml
+variables:
+  isl: 1024
+  osl: 512
+
+benchmark:
+  artifacts:
+    user_files:
+      - path: input_config.json
+        format: json                 # optional; inferred from content type
+        content:
+          isl: "{{ isl }}"
+          osl: "{{ osl }}"
+          endpoint: "{{ endpoint_url }}"
+          model: "{{ model }}"
+
+      - path: meta/notes.md          # subdirectories allowed
+        content: |
+          Run {{ job_name }} started at {{ epoch }}.
+          Targeting {{ model }} @ {{ endpoint_url }}.
+
+  models:
+    - my-org/my-model
+  endpoint:
+    type: chat
+    urls: ["http://my-frontend:8000"]
+  datasets:
+    - name: main
+      type: synthetic
+  phases:
+    - name: profiling
+      type: concurrency
+      concurrency: 10
+      requests: 100
+```
+
+Result in the run directory:
+
+```
+{artifact_dir}/               # the resolved artifacts.dir for this run
+├── input_config.json
+├── meta/
+│   └── notes.md
+└── ... (standard AIPerf artifacts)
+```
+
+Files land directly in the run directory — there is no extra per-run wrapper. The
+run directory is whatever `artifacts.dir` resolves to: the explicit
+`--artifact-dir` / `artifacts.dir` value, or `./artifacts/<auto-generated-name>`
+when neither was set. In-cluster the operator pins `artifacts.dir` to the
+`/results` container mount, so the files are harvested alongside the standard
+exports and appear under
+`/api/v1/results/<namespace>/<name>/runs/<epoch>/` and in `aiperf kube results`.
+
+## Schema
+
+Each entry is:
+
+| Field | Type | Required | Description |
+|---|---|---|---|
+| `path` | string | yes | Output path **relative** to the run directory. Subdirectories OK. Absolute paths and any segment equal to `..` are rejected. |
+| `format` | `json` \| `yaml` \| `text` | no | Serialization format. If omitted: `text` when `content` is a string, `json` otherwise. |
+| `content` | structured or string | yes | Templated value. Dict/list/scalar for `json`/`yaml`; string for `text`. Jinja2 expressions in any string leaf are rendered. |
+
+Format/content compatibility:
+- `format: json` or `format: yaml` requires structured `content` (dict/list/scalar).
+- `format: text` requires string `content`.
+
+**Rendered scalars are coerced in `json`/`yaml` output.** A leaf like `"{{ isl }}"`
+with `isl: 1024` is written as the number `1024`, not the string `"1024"`; `true`/`false`
+become booleans. Strings containing no Jinja2 markers are passed through untouched, so a
+hand-written `"1024"` stays a string. `format: text` never coerces.
+
+**Dict keys are not rendered.** Jinja2 expressions only resolve in string *values*,
+not in dict keys. `content: {"{{ model }}": "x"}` writes a file with the literal key
+`"{{ model }}"`, not the resolved model name. Put templated values where they belong
+— in values — or pre-flatten the dict before passing it to AIPerf.
+
+## Templating context
+
+Inside `content`, you can reference:
+
+**1. User-declared variables** — anything you put in the top-level `variables:` block of your config. Variables may reference each other (in any YAML order); cross-references are resolved in dependency order (a Kahn-style topological pass) at config-load time, so a derived variable like `total_concurrency: "{{ concurrency_per_gpu * deployment_gpu_count }}"` already holds its computed value by the time `user_files` rendering runs. Cycles raise `ConfigurationError` naming the participating variables.
+
+**2. System-injected names** (stable API):
+
+| Name | Type | Meaning |
+|---|---|---|
+| `epoch` | str | Run epoch identifier (e.g. `"1714000000"`). Locally: wall-clock seconds captured at run start, unless the run-directory basename is itself epoch-shaped (9-10 digits, optionally with a 6-digit uid suffix) or the literal `legacy`, in which case that basename is used. Under the operator: the same epoch key the run's PVC directory is named after, so `{{ epoch }}` matches the `/api/v1/results/<ns>/<name>/runs/<epoch>/` path the artifacts land under. |
+| `job_name` | str | Locally: run-directory basename (or the parent directory name when `epoch` came from the basename). Under the operator: the `AIPerfJob` name. |
+| `namespace` | str | Locally: value of `AIPERF_NAMESPACE`, empty string when unset. Under the operator: the CR's namespace. |
+| `model` | str | First model name from `benchmark.models` / `benchmark.model`; empty string when none. |
+| `endpoint_url` | str | First entry of `benchmark.endpoint.urls`; empty string when none. |
+| `artifact_dir` | str | Absolute path to the run directory. |
+
+**Collision rule:** if a user `variables:` key shadows an injected name, the injected name wins and a `WARNING` is logged when the render context is built at run start. Rename your variable.
+
+## Errors
+
+These are all fatal — the benchmark does not start.
+
+| Failure | Cause | Where you see it |
+|---|---|---|
+| Path validation | Absolute path, `..` segment, empty path, control chars | Config load (pydantic `ValidationError`) |
+| Format/content mismatch | e.g. `format: json` with `content: "string"` | Config load (pydantic `ValidationError`) |
+| Undefined variable | Template references a name not in context | Run start (`UserFileError`); message names the file path and the variable |
+| Path escape | Resolved path is not inside the run directory | Run start (`UserFileError`) |
+| Write failure | Disk full, permission denied, etc. | Run start (`UserFileError`); message includes resolved path and OS error |
+
+Config-load failures reject the YAML (and, for an `AIPerfJob`, the CR submitted by
+`aiperf kube profile`) before anything reaches the cluster. Run-start failures are
+raised by the process executing the benchmark: locally that aborts `aiperf
+profile`, and in-cluster it aborts the `system_controller` container before the
+benchmark begins, which the operator surfaces as `status.phase=Failed`.
+
+## Use cases
+
+- **Sidecar metadata** — produce an `input_config.json` for downstream tooling that expects
+  the dynamo-style deployment-shape file.
+- **Run notes** — write a `notes.md` summarizing what this run is for, who triggered it.
+- **Manifests** — emit a manifest a downstream pipeline will read.
+
+## Limitations (v1)
+
+- **Pre-run only.** Files render before the benchmark starts. Post-run files that include
+  results are tracked as a future extension.
+- **Files always overwrite.** No `overwrite: false` safety net.
+- **No `required: false`.** Every declared file must materialize successfully or the run aborts.
+- **Strict undefined.** A typo in `{{ varaibles_name }}` is a hard error, not a silent empty string.

+# Config Validation
+
+`aiperf kube validate` performs **client-side** validation of one or more
+`AIPerfJob` **or** `AIPerfSweep` YAML files against the Pydantic spec models that
+generate the CRD schema, plus Kubernetes resource-naming rules. It dispatches per
+document on the `kind:` field (`validate.py` `SUPPORTED_KINDS = {AIPerfJob,
+AIPerfSweep}`), routing to `AIPerfJobSpec` or `AIPerfSweepSpec`. It does not
+contact the cluster — making it safe to run in CI, pre-commit hooks, and local
+editors.
+
+> **Two layers, same rules.** `aiperf kube validate` runs the same structural
+> checks the apiserver enforces at `kubectl apply`. For the catalog of CEL
+> `x-kubernetes-validations` rules (shorthand-vs-canonical, mutual exclusion,
+> `apiHost ⇒ apiPort`, etc.) see [CRD Validation Rules](crd-validation.md).
+> Item-internal Pydantic validators (phase-name uniqueness, phase→dataset
+> reference integrity, "seamless not on first phase") run only at apply
+> time on the operator side because CEL can't see into opaque
+> preserve-unknown array items — the client-side `validate` command runs
+> them via Pydantic, so it catches both layers in one pass.
+
+## When to use
+
+| Situation | Tool |
+|---|---|
+| Validate YAML before `kubectl apply` or `aiperf kube profile` | `aiperf kube validate` (this doc) |
+| Check that a *live cluster* can actually schedule the job (JobSet CRD, RBAC, quotas, node capacity) | `aiperf kube preflight` |
+| Confirm the AIPerf CRDs are installed and see existing jobs | `aiperf kube list` |
+
+Think of `validate` as the offline static check and `preflight` as the online
+dynamic check. Both are cheap; run `validate` on every commit and `preflight`
+before the first apply of a new job.
+
+Typical integration points:
+
+- **CI gate** — run `find recipes -name perf.yaml -print0 | xargs -0 aiperf
+  kube validate --strict` in a GitHub Action or GitLab job before merging
+  changes to benchmark specs.
+- **Pre-commit** — catch typos in `spec.benchmark` fields before they reach the
+  cluster (see [Integration recipes](#integration-recipes)).
+- **IDE / Makefile target** — add `make validate-jobs` so contributors get fast
+  feedback without spinning up a cluster.
+
+## CLI reference
+
+```text
+aiperf kube validate <files...> [--strict] [--output text|json]
+```
+
+| Flag | Short | Type | Default | Description |
+|---|---|---|---|---|
+| `files` | — | `Path...` (positional, one or more) | — | Paths to `AIPerfJob` / `AIPerfSweep` YAML files, or to bare AIPerf config files (see [Bare AIPerf configs](#bare-aiperf-configs)). Globs are expanded by the shell. |
+| `--strict` | `-s` | bool | `false` | Treat warnings (unknown spec fields) as errors. |
+| `--output` | `-o` | `text` \| `json` | `text` | Output format. `text` prints a coloured per-file summary; `json` prints a machine-parseable array. |
+
+### Exit codes
+
+| Code | Meaning |
+|---|---|
+| `0` | All files passed. Warnings may still be present in non-strict mode. |
+| `1` | At least one file failed validation, or an internal error occurred. |
+
+### Examples
+
+```bash
+# Validate a single job file
+aiperf kube validate aiperfjob.yaml
+
+# Validate selected checked-in recipes
+aiperf kube validate recipes/llama-3-70b/vllm/agg/perf.yaml \
+  recipes/qwen3-32b/vllm/agg-round-robin/perf.yaml
+
+# Treat unknown spec fields as hard errors (recommended in CI)
+aiperf kube validate --strict aiperfjob.yaml
+
+# Machine-parseable output for scripting
+aiperf kube validate -o json aiperfjob.yaml | jq '.[] | select(.passed==false)'
+```
+
+## Bare AIPerf configs
+
+`validate` accepts two document shapes:
+
+- a wrapped CR (`apiVersion` + `kind` + `metadata` + `spec`), and
+- a **bare AIPerf config** — the Config-v2 shape with `models`, `endpoint`,
+  `datasets`, and `phases` at the top level, which is what
+  `aiperf kube sweep --config` consumes.
+
+A bare config is detected by the absence of `apiVersion`/`kind`, hoisted into
+the equivalent CR spec (envelope keys such as `sweep`, `multiRun`, `variables`
+stay at the spec level; everything else becomes `spec.benchmark`), and held to
+the same contract. The kind is inferred from the presence of a `sweep:` block,
+so a bare config with `sweep:` is checked against the `AIPerfSweep`
+cardinality rule and one without it against `AIPerfJob`.
+
+Every bare config emits a warning naming the contract that was applied:
+
+```text
+WARN: No apiVersion/kind: validating as a bare AIPerf config (the shape
+`aiperf kube sweep --config` accepts), against the AIPerfSweep contract.
+apiVersion/kind and metadata.name are not checked; wrap it in an explicit
+AIPerfSweep CR to validate those too.
+```
+
+Because a bare config has no CR wrapper, only the wrapper-only checks are
+skipped: `apiVersion`/`kind` and `metadata.name` are not validated. Everything
+else runs identically, including deployment-field and worker-count checks,
+credential transport, and unknown-field detection. A document that nests
+`benchmark:` explicitly may carry deployment fields (`image`, `podTemplate`,
+...) as its siblings; those stay at the spec level and are checked there, so a
+misspelled sibling is reported rather than silently dropped.
+
+Under `--strict` this warning is **not** promoted to an error — `--strict`
+governs unknown spec fields only.
+
+## What gets validated
+
+`validate` runs the following checks on each file, in order. Structural errors
+that make later checks impossible short-circuit the file (remaining checks are
+skipped for that file only). Bare AIPerf configs skip steps 3 and 4 (see
+[Bare AIPerf configs](#bare-aiperf-configs)), except for the
+`spec.benchmark`-shape rule in step 3, which still applies.
+
+1. **File reachability** — the path exists, is a regular file, and passes the
+   shared `safe_read_template_path` safety check.
+2. **YAML parse** — the document is valid YAML and decodes to a mapping.
+3. **Required top-level fields**:
+   - `apiVersion` must equal the current operator API version
+     (`aiperf.nvidia.com/v1alpha1`).
+   - `kind` must be one of `AIPerfJob` or `AIPerfSweep`. The kind selects
+     which spec model the document is validated against; an `AIPerfJob` must
+     omit `spec.sweep` while an `AIPerfSweep` requires it.
+   - `metadata` must be a mapping with a `name` field.
+   - `spec` must be a mapping.
+   - `spec.benchmark` must be a mapping containing at least one of `models` or
+     `endpoint`.
+4. **Kubernetes naming** — `metadata.name` must:
+   - be at most **253 characters** (`K8S_NAME_MAX_LENGTH`), and
+   - match `K8S_NAME_PATTERN`, the RFC 1123 *label* pattern
+     `^[a-z0-9]([a-z0-9-]*[a-z0-9])?$` (lowercase alphanumerics and hyphens only;
+     must start and end with an alphanumeric — dots are rejected).
+5. **Unknown field detection** (warning by default, error with `--strict`):
+   - **Top-level `spec`** is compared against `KNOWN_SPEC_FIELDS`
+     (`validate.py`) — the deployment fields `image`, `imagePullPolicy`,
+     `keepFailedPods`, `resourceMode`, `connectionsPerWorker`,
+     `timeoutSeconds`, `ttlSecondsAfterFinished`, `resultsTtlDays`, `cancel`,
+     `podTemplate`, `scheduling`, `skipEndpointCheck`, `failurePolicy`; the
+     envelope fields `schemaVersion`, `sweep`, `multiRun`, `plot`, `variables`,
+     `randomSeed`, `noSweepTable`, `childMetadata`; plus the nested `benchmark` block. Stray top-level keys
+     often mean a benchmark-config field was placed at `spec.<x>` instead of
+     `spec.benchmark.<x>` — the warning message says so explicitly.
+   - **`spec.benchmark`** is compared against `CONFIG_FIELDS`
+     (`kubernetes/spec_converter.py`): every `BenchmarkConfig` model field, its
+     serialization aliases, plus the shorthand keys `model`, `dataset`,
+     `warmup`, `profiling`.
+6. **`AIPerfConfig` construction** — `spec.benchmark` is fed through
+   `AIPerfJobSpecConverter.to_aiperf_config()`, which performs the same env-var
+   and Jinja2 expansion as a local CLI file load, then validates the result
+   against the Pydantic model. Type, range, and cross-field errors surface
+   here.
+7. **Endpoint sanity** — at least one model name must be present, and every
+   entry in `endpoint.urls` must start with `http://` or `https://`.
+8. **Deployment-config extraction** — top-level spec fields are materialised
+   into a `DeploymentConfig` via `to_deployment_config()`. Catches malformed
+   `podTemplate`, invalid `resourceMode`, bad `scheduling` blocks, etc.
+9. **Endpoint credential transport** — credential-bearing endpoint fields
+   must have the matching Secret-backed pod environment (`AIPERF_INJECTED_API_KEY`,
+   `AIPERF_INJECTED_HEADERS`, or `AIPERF_INJECTED_ENDPOINT_URLS`). Literal
+   secrets and plain-value environment variables fail before deployment. This
+   check is skipped when steps 6–8 already produced an error, since it needs a
+   well-formed config and deployment to inspect.
+10. **Worker-count calculation** — `calculate_workers()` must complete. It
+   honours an explicit `benchmark.runtime.workers` override, otherwise computes
+   `ceil(max phase concurrency / connectionsPerWorker)`, always clamped to at
+   least `1`. Unparsable concurrency and worker values fall back to `1` rather
+   than raising, and a `connectionsPerWorker` that is numeric but below `1`
+   (including `0`, `false`, and subnormal floats such as `1e-320`) is
+   neutralized to `1` for this step — step 8 has already reported it against
+   the field's `>= 1` bound, so re-reporting it here would only duplicate that
+   error. This step therefore reports only a **non-numeric**
+   `connectionsPerWorker` (`Worker calculation failed: ...`), where the
+   arithmetic genuinely cannot proceed.
+11. **Kind/sweep cardinality and kind-specific spec validation** —
+    `spec.sweep` must be absent on an `AIPerfJob` and a non-empty mapping on an
+    `AIPerfSweep`, mirroring each CRD's CEL rule. Then the Config-v2 envelope is
+    rendered (unknown top-level keys stripped first, so pydantic does not
+    re-report them) before the complete `AIPerfJobSpec` or `AIPerfSweepSpec`
+    check. Raw Jinja values therefore validate as their resolved numeric or
+    structured types, while unknown variables and invalid rendered values still
+    fail closed.
+
+> Note: `validate` is intentionally conservative about what it considers
+> "unknown". Any key in `CONFIG_FIELDS` (every `BenchmarkConfig` field, its
+> aliases, and the shorthand keys) is accepted under `spec.benchmark`, so
+> newly added config fields do not require a docs update to this page.
+
+## JSON output schema
+
+With `-o json`, a single JSON array is printed to stdout. Each element
+corresponds to one input file, in the order given on the command line.
+stdout carries nothing but that array — long paths and error strings are
+never line-wrapped, and any diagnostics the validator logs are retargeted
+to stderr — so the document is parseable when redirected or run in CI.
+
+Every input file always appears in the array. No individual file can abort the
+batch: a malformed value is reported against the file that carries it, and the
+remaining files are still validated. `jq -e` recipes therefore always receive a
+complete document, even when the first file on the command line is the broken
+one.
+
+```jsonc
+[
+  {
+    "path": "string",         // filesystem path as provided
+    "passed": true,           // bool; true iff errors is empty
+    "errors":   ["string..."], // fatal issues (empty when passed=true)
+    "warnings": ["string..."]  // non-fatal issues; upgraded to errors under --strict
+  }
+]
+```
+
+### Example — all files pass
+
+```json
+[
+  {
+    "path": "recipes/llama-3-70b/vllm/agg/perf.yaml",
+    "passed": true,
+    "errors": [],
+    "warnings": []
+  }
+]
+```
+
+### Example — multiple errors
+
+Unknown-field messages land in `warnings` by default and move into `errors`
+under `--strict`:
+
+```json
+[
+  {
+    "path": "recipes/broken.yaml",
+    "passed": false,
+    "errors": [
+      "kind: expected one of ['AIPerfJob', 'AIPerfSweep'], got 'AIPerfConfig'",
+      "metadata.name: 'My_Benchmark' is not a valid Kubernetes resource name (must match [a-z0-9][a-z0-9-]*[a-z0-9])",
+      "endpoint.urls: 'localhost:8000' must start with http:// or https://"
+    ],
+    "warnings": [
+      "Unknown spec fields (did you mean to put these under spec.benchmark?): models, endpoint"
+    ]
+  }
+]
+```
+
+Scripting tip — fail a CI job on any warning, not just errors:
+
+```bash
+find recipes -name perf.yaml -print0 \
+  | xargs -0 aiperf kube validate -o json \
+  | jq -e 'all(.passed and (.warnings | length == 0))'
+```
+
+## Integration recipes
+
+### Pre-commit hook
+
+Add to `.pre-commit-config.yaml`:
+
+```yaml
+- repo: local
+  hooks:
+    - id: aiperf-kube-validate
+      name: aiperf kube validate
+      entry: aiperf kube validate --strict
+      language: system
+      files: ^recipes/.*\.ya?ml$
+      pass_filenames: true
+```
+
+### GitHub Actions step
+
+```yaml
+- name: Validate AIPerfJob specs
+  run: |
+    uv tool install aiperf
+    find recipes -name perf.yaml -print0 | xargs -0 aiperf kube validate --strict
+```
+
+In a matrix/monorepo setup, use JSON output to surface a compact report:
+
+```yaml
+- name: Validate AIPerfJob specs
+  run: |
+    find recipes -name perf.yaml -print0 \
+      | xargs -0 aiperf kube validate -o json > validation.json
+    jq -r '.[] | select(.passed==false) | "::error file=\(.path)::\(.errors[0])"' validation.json
+```
+
+### Makefile target
+
+```makefile
+.PHONY: validate-jobs
+validate-jobs:
+	find recipes -name perf.yaml -print0 | xargs -0 aiperf kube validate --strict
+```

+Most runs follow the same path. Commands marked "local" run entirely on your
+laptop; commands marked "cluster" talk to the Kubernetes API server.

+```
+
+The commands on the left-hand column (init, validate, preflight) are
+pre-flight work: they write or inspect files and poke at the cluster but
+never create workload resources. `profile` is the one command that actually
+deploys. `attach`, `results`, `logs`, and `debug` all operate on an
+already-deployed benchmark; `list --watch` continuously refreshes cluster
+status.
+
+## Stage 1: `init` — scaffold a config
+
+`aiperf kube init` renders one of the bundled AIPerf config templates
+(`src/aiperf/config/templates/`), wraps it in an `AIPerfJob` CR shell, and
+prints it to stdout — or writes it to a file with `-o` / `--output`.
+
+```bash
+# Print the default 'minimal' template to stdout
+aiperf kube init
+
+# Browse the bundled templates
+aiperf kube init --list
+aiperf kube init --search goodput
+
+# Pick a template and pre-fill model / endpoint, write to benchmark.yaml
+aiperf kube init -t goodput_slo \
+    --model Qwen/Qwen3-0.6B \
+    --url http://server:8000 \
+    --output benchmark.yaml
+```
+
+The output is an `apiVersion: aiperf.nvidia.com/v1alpha1`, `kind: AIPerfJob`
+document: the template body lands under `spec`, and commented-out blocks for
+deployment options, pod customization, and Kueue scheduling are appended. It is
+the same CR format the operator accepts, so you can either hand it to
+`aiperf kube profile --config benchmark.yaml` or `kubectl apply -f
+benchmark.yaml` it directly. `--job-name` (default `my-benchmark`) sets
+`metadata.name`. See [init-and-generate.md](./init-and-generate.md) for the
+full flag list and a walkthrough of the emitted template.
+
+`init` writes nothing else — no cluster state, no `last_kube_benchmark.json`,
+no container image references. Image, workers, and namespace are still
+supplied at `profile` time via CLI flags.
+
+## Stage 2: `validate` — offline config check
+
+`aiperf kube validate` reads one or more YAML files and validates them
+against the CRD schema and the `AIPerfConfig` model, without touching the
+cluster. Use it in CI or in a pre-commit hook to catch typos before you
+deploy.
+
+```bash
+aiperf kube validate benchmark.yaml
+find recipes -name perf.yaml -print0 | xargs -0 aiperf kube validate --strict
+aiperf kube validate -o json benchmark.yaml
+```
+
+See [validate.md](./validate.md) for the full list of checks (RFC 1123 name
+validation, endpoint presence, worker math, unknown-field detection, etc.)
+and CI recipes.
+
+## Stage 3: `preflight` — cluster-side check
+
+`aiperf kube preflight` confirms that the cluster you are about to deploy
+into is actually capable of running the benchmark. It is the first command
+that contacts the cluster.
+
+```bash
+# Basic
+aiperf kube preflight
+
+# With image and endpoint probes and a worker-count projection
+aiperf kube preflight \
+    --image aiperf:latest \
+    --endpoint-url http://server:8000 \
+    --workers 8
+
+# JSON output for CI
+aiperf kube preflight -o json
+```
+
+It verifies connectivity, API versions, RBAC, node capacity vs. worker
+projection, image pull-ability, and endpoint reachability. See
+[preflight.md](./preflight.md) for the full check list and the JSON schema.
+Running `validate` and `preflight` together gives you full coverage of "is
+the config sane?" plus "is the cluster ready?".
+
+## Stage 4: `profile` — deploy the benchmark
+
+This is the load-bearing command. It parses a config (from CLI flags or from
+the YAML file you validated), picks a deployment mode, submits resources to
+the cluster, and optionally streams logs until the benchmark finishes.
+
+### Operator mode vs. direct mode
+
+By default, `profile` looks for the `aiperfjobs.aiperf.nvidia.com` CRD on the
+cluster (see `operator_available` in
+`src/aiperf/cli_commands/kube/profile_deploy.py`). Use `--operator` to select
+operator mode without that cluster-scoped discovery request, or
+`--no-operator` to select direct mode.
+
+- **Operator mode (default when CRD is present).** `profile` creates a
+  single `AIPerfJob` custom resource. The in-cluster operator reconciles the
+  CR and owns the lifecycle of the downstream `JobSet`, `ConfigMap`, `Role`,
+  and `RoleBinding`. When the run reaches a terminal phase the operator's
+  completion handler copies the results onto a shared operator PVC; on a
+  failure it instead salvages whatever partial checkpoint files the controller
+  had written. Nothing is harvested incrementally mid-run. `profile` never
+  creates a namespace: the target namespace must already exist. This lets
+  namespace-scoped tenants submit AIPerfJobs without cluster-wide CRD-read or
+  Namespace-create permission by combining `--operator` with `--namespace`.
+
+- **Direct mode (CRD absent, or forced with `--no-operator`).** `profile`
+  skips the operator and creates the `ConfigMap`, `Role`, `RoleBinding`, and
+  `JobSet` itself, in a namespace that must already exist. There is no CR and no operator-managed
+  PVC; results stay on the pod filesystem until you pull them with `aiperf
+  kube results --from-pods`. See [direct-mode.md](./direct-mode.md). The
+  JobSet TTL defaults to 8 hours in direct mode (vs. 5 minutes in operator
+  mode) specifically so pods stay alive long enough for manual results
+  retrieval.
+
+Both modes accept the same flags. To preview the manifests without
+submitting them, use `aiperf kube generate --operator` or `aiperf kube
+generate --no-operator` instead — or pass `--dry-run` to `profile`, which
+prints the would-be CR as JSON in operator mode, or the raw manifests as
+multi-document YAML in direct mode. Both forms write the payload to stdout
+verbatim, so `--dry-run > job.json` and `--dry-run | jq` stay valid however
+long the image reference or endpoint URL is.
+
+#### `--dry-run` fidelity
+
+`--dry-run` is intentionally usable with no cluster reachable at all, which
+is what makes `--no-operator --dry-run > bench.yaml` (see
+[direct-mode.md](./direct-mode.md)) work from a laptop with no kubeconfig.
+Two consequences follow, and both mean dry-run output can differ from what a
+real run would submit:
+
+1. **The mode shown is assumed, not detected.** `--dry-run` skips the
+   `operator_available` CRD probe entirely, so with neither `--operator` nor
+   `--no-operator` it always renders the `AIPerfJob` CR — even on a cluster
+   where the CRD is absent and a real run would have fallen back to direct
+   mode. `profile` prints a note to stderr saying so; pass `--no-operator`
+   to preview direct-mode manifests. Only the *unset*-flag row diverges:
+
+   | `--dry-run` | operator flag | AIPerfJob CRD | Path previewed / taken | Cluster probed |
+   |---|---|---|---|---|
+   | yes | unset | present | operator | no |
+   | yes | unset | **absent** | **operator** | no |
+   | yes | `--operator` | either | operator | no |
+   | yes | `--no-operator` | either | direct | no |
+   | no | unset | present | operator | yes |
+   | no | unset | **absent** | **direct** | yes |
+   | no | `--operator` | either | operator | no |
+   | no | `--no-operator` | either | direct | no |
+
+2. **The CR is printed before validation.** In operator mode a real run pipes
+   the spec through `validate_job_spec` and submits the canonicalized Pydantic
+   dump, whereas `--dry-run` prints the literal pre-validation spec so you can
+   see exactly what you authored. For CLI-flag input the two are byte-identical,
+   but a hand-authored `AIPerfJob` CR passed with `-f` can differ: snake_case
+   envelope keys such as `ttl_seconds_after_finished` are printed as-is by
+   dry-run and submitted as `ttlSecondsAfterFinished`, and a spec carrying an
+   unknown key is printed happily by dry-run while a real submission exits 1
+   with `Unknown top-level envelope key(s)`. Use `aiperf kube validate` (or a
+   real submission) to check a CR's validity; `--dry-run` does not.
+
+### Foreground vs. `--detach`
+
+Once the resource is created, `profile` decides whether to block:
+
+- **Foreground (the default, when stdout is a TTY).** In operator mode the CLI
+  polls the AIPerfJob CR every 2 seconds via `watch_job`, logging phase/worker
+  heartbeats and condition transitions, until the phase reaches `Completed`,
+  `Failed`, or `Cancelled` — or a hard 600-second timeout raises `TimeoutError`.
+  It does not port-forward to the controller pod; use `aiperf kube attach` after
+  submission for real-time progress streaming. Ctrl+C returns to the shell but
+  leaves the cluster-side run intact. For benchmarks that run longer than 600
+  seconds, pass `--detach` and monitor separately with `aiperf kube attach`.
+  Direct mode takes a different foreground path (`wait_or_detach` ->
+  `auto_attach_workflow`): it waits up to 300 seconds for the controller pod to
+  reach `Running`, tails that pod's `control-plane` container, and on completion
+  downloads all artifacts plus per-pod logs into `./artifacts/<job_id>/`, so a
+  separate `aiperf kube results` call is not required.
+- **`--detach` (or any non-interactive stdout, e.g. a pipe or CI).** The CLI
+  submits the resource, prints "Detached" with a hint about how to re-attach,
+  and exits immediately. The benchmark continues running in the cluster.
+  Non-interactive environments auto-upgrade to detach mode with a warning —
+  see `wait_or_detach` in `src/aiperf/cli_commands/kube/profile_deploy.py`.
+
+### The "last benchmark" handoff
+
+As part of a successful submit, `profile` writes
+`~/.aiperf/last_kube_benchmark.json` — this is how the rest of the workflow
+commands default their `job_id` and `--namespace` to "whatever you just
+deployed". The file is written by both operator-mode (`deploy_via_operator`)
+and direct-mode paths. See [Last benchmark persistence](#last-benchmark-persistence)
+below for details.
+
+Operator jobs and sweeps also record their custom-resource kind. Destructive
+commands use that kind when no `job_id` is supplied, so a same-named
+`AIPerfJob` and `AIPerfSweep` cannot redirect the last-benchmark shorthand to
+the wrong resource. Legacy and direct-mode records remain readable without a
+kind.
+
+### Common `profile` invocations
+
+```bash
+# From a CR-format YAML file (validated above), with operator auto-detect
+aiperf kube profile \
+    --config benchmark.yaml \
+    --image aiperf:latest \
+    --total-workers 10
+
+# From pure CLI flags, foreground, follows logs until done
+aiperf kube profile \
+    --model Qwen/Qwen3-0.6B \
+    --url http://server:8000 \
+    --image aiperf:latest \
+    --total-workers 8
+
+# CI / scripted: deploy and return control immediately
+aiperf kube profile \
+    --config benchmark.yaml \
+    --image aiperf:latest \
+    --detach
+
+# Force direct mode even if the operator is installed
+aiperf kube profile \
+    --model Qwen/Qwen3-0.6B \
+    --url http://server:8000 \
+    --image aiperf:latest \
+    --no-operator
+
+# Pre-provisioned tenant namespace; skip cluster-scoped CRD discovery
+aiperf kube profile \
+    --config benchmark.yaml \
+    --namespace team-a-benchmarks \
+    --operator
+```
+
+## Stage 5: `attach` — re-connect to a detached run
+
+If you detached (or Ctrl-C'd out of a foreground run), `aiperf kube attach`
+re-opens the log stream. It port-forwards to the controller pod's API
+container and streams real-time progress over WebSocket.
+
+```bash
+# Re-attach to the last deployed benchmark
+aiperf kube attach
+
+# Re-attach to a specific job
+aiperf kube attach my-benchmark --namespace aiperf-bench
+```
+
+Called without arguments, `attach` reads
+`~/.aiperf/last_kube_benchmark.json` for the job-id and namespace, so the
+zero-argument form works as long as you haven't deployed a second benchmark
+in between. Ctrl+C disconnects from the stream without killing the
+benchmark.
+
+### Cancelling a run
+
+`aiperf kube cancel` patches `spec.cancel: true` on the CR. The operator
+tears down the JobSet, stamps `status.phase=Cancelled`, and emits a
+`Cancelled` event; already-terminal benchmarks are left alone. A job created
+with `spec.cancel: true` is terminalized the same way before any endpoint
+probe, preflight check, or Kubernetes benchmark resource is created.
+
+```bash
+# Cancel the last deployed benchmark
+aiperf kube cancel
+
+# Cancel a specific job, a whole sweep, or one variation of it
+aiperf kube cancel my-benchmark --namespace aiperf-bench
+aiperf kube cancel my-sweep
+aiperf kube cancel shared-name --kind sweep
+aiperf kube cancel my-sweep -v 7
+```
+
+When an `AIPerfJob` and `AIPerfSweep` share a name, pass `--kind job` or
+`--kind sweep`. The CLI refuses an ambiguous destructive command instead of
+selecting one kind by lookup order.
+
+Cancelling is not the same as deleting: the CR (and any results already
+harvested) stays, so `aiperf kube results` still works afterwards.
+
+### Retiring and removing runs
+
+```bash
+# Let a finished benchmark's controller pod exit and free its reservation.
+# Refuses while the run is still going -- cancel it first.
+aiperf kube shutdown my-benchmark
+
+# Delete one benchmark; the JobSet and pods go with it via ownerReferences.
+aiperf kube delete my-benchmark --force
+aiperf kube delete shared-name --kind sweep --force
+
+# Bulk-remove finished benchmarks from a namespace (running ones are left alone)
+aiperf kube cleanup --dry-run
+aiperf kube cleanup
+
+# Include running benchmarks; each is cancelled before it is removed
+aiperf kube cleanup --all --force
+```
+
+`delete` and `cleanup` prompt before removing anything and refuse outright
+when stdin is not a terminal, so a CI job cannot delete by accident -- pass
+`--force` when you mean it. Results already harvested onto the operator's PVC
+survive all three commands.
+
+Neither command touches the namespace itself. AIPerf never creates one, so
+removing it is your call: `kubectl delete namespace <ns>`.
+
+## Stage 6: `results` — pull the artifacts
+
+When the run is complete (phase `Completed` in `aiperf kube list`), fetch
+the artifacts:
+
+```bash
+# Default: operator mode — reads from the operator's PVC via HTTP.
+aiperf kube results
+
+# Custom output directory (default is ./artifacts/{name})
+aiperf kube results --output ./out
+
+# Direct mode, or fallback if the operator hasn't imported results yet
+aiperf kube results --from-pods
+
+# Direct mode + let the controller pod exit cleanly
+aiperf kube results --from-pods --shutdown
+
+# Summary only (no per-request parquet)
+aiperf kube results --summary-only
+```
+
+`results` has two retrieval paths:
+
+1. **Operator PVC (default).** Calls the operator's results API at
+   `/api/v1/results/...` over a port-forward to the operator pod. Works
+   even after the benchmark pods have been TTL-deleted, because the operator
+   copied everything into its persistent volume. See
+   [results-api.md](./results-api.md) for the HTTP surface and PVC layout.
+
+2. **`--from-pods`.** Goes directly to the benchmark controller pod's HTTP
+   API. On the default `--all` path that API is the only tier — if it fails,
+   the download fails. The `kubectl cp` fallback exists only on the
+   `--summary-only` path, which tries the API first and copies from the
+   `control-plane` container if it fails. Required for direct-mode
+   deployments; useful in operator mode if the operator hasn't synced yet or
+   if you want the raw on-pod artifact tree. Combined with `--shutdown`, the
+   controller pod exits cleanly after the copy so the JobSet can complete.
+
+The command exits with status 1 when the target cannot be resolved or any
+requested result download fails. This makes a successful exit safe to use as
+the artifact-collection gate in CI; partial sweep downloads also fail the
+command even though successfully downloaded child artifacts remain on disk.
+
+Output directory defaults to `./artifacts/{benchmark-name}`, or
+`./artifacts/{namespace}__{benchmark-name}__{epoch}` when you pin a historical
+run with `--run` (see `aiperf kube results list-runs`) so the pinned download
+cannot overwrite the latest-run directory.
+
+## Intermediate commands
+
+These don't fit the linear sequence but are part of everyday operation:
+
+- **`aiperf kube list`** — enumerates AIPerfJob CRs (falls back to JobSet
+  lookup in direct mode), with `--running`, `--completed`, `--failed`,
+  `--watch`, and `-A`. This is how you discover names you've forgotten.
+- **`aiperf kube logs`** — raw pod logs, with `--follow`, `--tail`,
+  `--container`, and `--output` (save per-pod files to a directory).
+- **`aiperf kube debug`** — one-shot diagnostic: pod states, recent events,
+  node resources, and a slice of logs from any pod with problems. See
+  [debug-command.md](./debug-command.md).
+- **`aiperf kube dashboard`** — port-forwards the operator's results server
+  UI and opens it in your browser. Useful for browsing multiple past
+  benchmarks stored on the operator PVC.
+- **`aiperf kube sweep`** — deploys an `AIPerfSweep` (parameter sweep or
+  multi-run) instead of a single `AIPerfJob`. See [Running Sweeps on Kubernetes](../tutorials/sweeps.md#running-sweeps-on-kubernetes).
+- **`aiperf kube show`** — renders an `AIPerfJob` CR with Jinja2 and env-var
+  substitutions resolved, so you can see what the operator will actually read.
+
+## Stage 7: cleanup
+
+Benchmark resources carry a TTL, but you often want to reclaim space (and the
+CR name) sooner.
+
+- **Operator mode:**
+  ```bash
+  aiperf kube delete my-benchmark -n my-benchmarks
+  # or, equivalently, straight through kubectl:
+  kubectl delete aiperfjob my-benchmark -n my-benchmarks
+  ```
+  The downstream JobSet, ConfigMap, Role, and RoleBinding carry
+  ownerReferences back to the CR, so Kubernetes garbage-collects them. The
+  operator's `on_delete` handler deliberately does not delete them itself; it
+  only sets the in-process cancellation flag, closes the cached
+  `ProgressClient`, and drops the job's `runs_index` rows. Deleting through
+  `aiperf kube delete` also clears the matching `last_kube_benchmark.json`
+  entry; deleting through `kubectl` leaves it stale, so subsequent
+  `attach`/`results` calls will report "not found" until you pass the job ID
+  (positional) and `-n` / `--namespace` explicitly, or deploy a new benchmark
+  to repopulate.
+
+- **Direct mode:**
+  ```bash
+  kubectl delete jobset my-benchmark -n my-benchmarks
+  ```
+  Delete the ConfigMap, Role, and RoleBinding before re-deploying the same
+  name. Direct mode reuses an existing Namespace but refuses to adopt any
+  existing workload or RBAC resource because it cannot prove that resource
+  belongs to the new invocation. The JobSet `ttl_seconds` defaults to 28800
+  (8 hours) so the pods stay alive long enough for `aiperf kube results
+  --from-pods`; after TTL, Kubernetes garbage-collects the JobSet for you.
+
+## Last benchmark persistence
+
+The file `~/.aiperf/last_kube_benchmark.json` is the glue that lets
+`attach`, `results`, `logs`, `debug`, `cancel`, `delete`, and `shutdown`
+default to the most recently deployed benchmark.
+
+The format is:
+
+```json
+{
+  "job_id": "qwen3-0-6b-openai-throughput",
+  "namespace": "my-benchmarks",
+  "name": "my-benchmark",
+  "kind": "AIPerfJob"
+}
+```
+
+`job_id` and `namespace` are always present. `name` is the
+user-supplied-or-generated friendly name and is written only when set.
+`kind` is `AIPerfJob` or `AIPerfSweep` and is absent for direct-mode and
+legacy records; any other value is discarded on read. See
+`LastBenchmarkInfo`, `save_last_benchmark`, and `get_last_benchmark` in
+`src/aiperf/kubernetes/console.py`.
+
+Default-resolution logic lives in `resolve_job_id_and_namespace` in
+`src/aiperf/kubernetes/cli_helpers.py`: if `job_id` is explicitly passed,
+the flag wins. Otherwise the file is consulted, and if the file is missing
+the command prints an error and exits.
+
+**Multi-cluster pitfall.** The file is per-user, not per-kubeconfig or
+per-context. If you alternate between clusters in one shell session, always
+pass the job ID positionally plus `-n` / `--namespace` (and `--kube-context`)
+explicitly. Otherwise "I deployed to
+staging and `results` is reading from prod" is an easy way to chase a ghost.
+
+### Command interaction matrix

+
+## Exit-code convention for target-addressing commands
+
+Eleven `aiperf kube` subcommands take a benchmark name or job ID. They split
+into two groups, and the split is deliberate: **validation and retrieval
+commands gate, addressing commands narrate.**
+
+| Group | Commands | Non-zero exit on… |
+| --- | --- | --- |
+| **Gating** — the command's whole purpose is to produce a verdict or a file | `validate`, `preflight`, `results`, `results list-runs` | any failure, including a missing target *and* a partial or failed download |
+| **Addressing** — the command reports on whatever it finds | `attach`, `logs`, `cancel`, `delete`, `shutdown`, `debug`, `list` | nothing, **except** `attach` and `logs`, which exit `1` when the named target does not exist |
+
+`attach` and `logs` are the two commands people reach for in CI to answer "is
+this benchmark there?", so a missing target is an error for them. A target that
+exists but has nothing left to show — pods already garbage-collected, a
+`--container` filter that matched nothing, a container that logged zero lines —
+is **not** an error: the command says so and exits `0`.
+
+Both accept `--ignore-not-found`, spelled and behaving like `kubectl`'s flag:
+the diagnostic is still printed, only the exit status is suppressed. Use it in
+teardown scripts that must tolerate an already-deleted benchmark.
+
+```bash
+# Gate a pipeline on the benchmark existing
+aiperf kube logs "$JOB" --tail 1 >/dev/null || exit 1
+
+# Best-effort log capture during teardown, must not fail the job
+aiperf kube logs "$JOB" -o ./triage --ignore-not-found
+```
+
+`cancel`, `delete`, `shutdown`, `debug`, and `list` intentionally stay at exit
+`0` for a missing target: they are idempotent or exploratory, and "the thing you
+asked me to stop is already gone" is the desired end state, not a failure.
+
+## Common end-to-end recipes
+
+### Quick smoke test, foreground
+
+Typical developer loop: validate, deploy, watch logs inline, pull results.
+
+```bash
+aiperf kube init --output smoke.yaml
+# edit smoke.yaml: set models, endpoint, datasets
+aiperf kube validate smoke.yaml
+aiperf kube preflight --image aiperf:latest --endpoint-url http://server:8000
+aiperf kube profile --config smoke.yaml --image aiperf:latest
+aiperf kube results
+```
+
+Because `profile` stays in the foreground, the last three commands are a
+tight cycle: change config, re-run `profile`, inspect artifacts.
+
+### Long-running benchmark, detached
+
+For multi-hour runs from a laptop, CI, or SSH session, detach up front and
+poll with `list --watch`.
+
+```bash
+aiperf kube profile --config long.yaml --image aiperf:latest --detach
+# ... walk away; come back later ...
+aiperf kube list --watch --running # continuously refresh running jobs
+aiperf kube debug                  # diagnose a job that looks stuck
+aiperf kube results                # once list reports Completed
+```
+
+CI systems automatically hit this path because stdout is not a TTY — no need
+to pass `--detach` explicitly. Use `kubectl wait --for=condition=Complete aiperfjob/<name>` if you need
+scripted completion detection; the CRD exposes `Complete` / `Failed`
+conditions with the same semantics as a `batchv1.Job`. Every terminal
+transition, including a permanent validation or preflight failure during
+creation, stamps `status.completionTime` for TTL and history consumers.
+
+### Multi-user shared cluster
+
+On a cluster shared by multiple users, deploy each benchmark into its own
+namespace and use [Kueue](./kueue.md) to gate admission.
+
+```bash
+aiperf kube profile \

+### Kubernetes auto-discovery
+
+When AIPerf runs in Kubernetes, `server_metrics.discovery` can add inference-pod
+Prometheus endpoints to the endpoints derived from `endpoint.urls` and the explicit
+`server_metrics.urls` list:
+
+```yaml
+server_metrics:
+  discovery:
+    mode: kubernetes
+    namespace: dynamo-server
+    label_selector: app.kubernetes.io/name=dynamo
+    timeout_seconds: 10
+```
+
+`mode: auto` (the default) uses Kubernetes discovery only when AIPerf is running
+in-cluster. `mode: kubernetes` requires the Kubernetes path and warns when used
+outside a cluster. `mode: disabled` uses only URL-derived and explicit endpoints.
+Discovery is best-effort: a timeout or API error does not prevent the benchmark
+from using its other endpoints.
+
+If `namespace` is omitted, discovery searches only the benchmark pod's own
+namespace, resolved from `AIPERF_NAMESPACE` or its mounted ServiceAccount namespace.
+It never silently expands to cluster scope. `namespace: "*"` is the explicit
+all-namespace mode and requires a cluster-scoped `pods: list` grant. To discover a
+server in another named namespace, add that namespace to the operator chart's
+`serverMetricsDiscoveryNamespaces` value; if the benchmark pod uses a custom
+ServiceAccount, use the chart's `{namespace, serviceAccounts}` entry form. See
+[Kubernetes RBAC and security](../kubernetes/rbac-security.md#benchmark-pod-permissions).
+
+The built-in eligibility rules select Dynamo's
+`nvidia.com/metrics-enabled=true` pods, pods with
+`aiperf.nvidia.com/metrics-paths`, and recognized inference-server images. A supplied
+`label_selector` explicitly selects matching pods. A generic
+`prometheus.io/scrape=true` annotation alone is not enough, which avoids collecting
+unrelated Loki, Grafana, and cluster-monitoring endpoints. Eligible pods can use the
+standard `prometheus.io/{port,path,scheme}` annotations; the AIPerf paths annotation
+accepts a comma-separated path list. Discovered paths are used as declared after
+adding a leading slash when needed; AIPerf does not append `/metrics` to a custom
+annotation path.
+
+#### RBAC prerequisites
+
+Discovery lists pods using the benchmark pod's ServiceAccount:
+
+| `discovery.namespace` | Searches | RBAC required |
+|---|---|---|
+| omitted | The benchmark pod's own namespace | None beyond the operator chart's normal benchmark Role (`pods: get/list/watch`) |
+| A named inference namespace | That namespace | Add it to `serverMetricsDiscoveryNamespaces`, using `{namespace, serviceAccounts}` when benchmarks use a custom ServiceAccount |
+| `"*"` | All namespaces | A manually provisioned ClusterRole with `pods: list`, bound to the benchmark ServiceAccount; the chart intentionally does not create this grant |
+
+For example, to allow benchmarks in the chart-configured benchmark namespace to
+discover Dynamo in `dynamo-server`:
+
+```bash
+helm upgrade aiperf-operator deploy/helm/aiperf-operator \
+  --namespace aiperf-system \
+  --reuse-values \
+  --set 'serverMetricsDiscoveryNamespaces={dynamo-server}'
+```
+
+Then set `server_metrics.discovery.namespace: dynamo-server` in the AIPerf YAML.
+A denied pod list emits a warning naming the namespace and required grant; it does
+not fail the benchmark.

+### Multimodal batch sizes
+
+For multimodal workloads, `random_pool` supports per-modality batch-size flags that control how many items are packed into each request:
+
+| Flag | Field | Default | Notes |
+|---|---|---|---|
+| `--prompt-batch-size N` | `prompt_batch_size` | 1 | Text items per request. Set to `0` to disable text inputs entirely. |
+| `--image-batch-size N` | `image_batch_size` | 1 | Images per request. Set to `0` to disable image inputs. |
+| `--audio-batch-size N` | `audio_batch_size` | 1 | Audio items per request. Set to `0` to disable audio inputs. |
+| `--video-batch-size N` | `video_batch_size` | 1 | Video items per request. Set to `0` to disable video inputs. |
+
+Setting a batch size to `0` for a modality that is absent from the pool is a no-op: it neither suppresses anything nor counts as batching, so `--image-batch-size 0` against a single-file text-only pool leaves that pool sampled normally. A configuration where *every* modality is either absent from the pool or set to `0` produces empty requests and is rejected, since there is nothing left to send. Directory input rejects any batch size other than `1` regardless of which modalities are present, because pool contents are not known at config time -- see below.
+
+These flags are only valid with `format: random_pool` (set via `--custom-dataset-type random_pool` on the CLI, or `format: random_pool` directly in a YAML dataset config -- either selects the same format). Using them with other file dataset formats (e.g. `mooncake_trace`) is an error.
+
+Batch sizes other than 1 are also rejected outright whenever batching would discard pool identity: (1) multiple separately named pools -- directory input (multiple files, e.g. `queries.jsonl` / `passages.jsonl`) or inline YAML `records:` with multiple top-level keys (e.g. `records: {queries: [...], passages: [...]}`) both flatten into one anonymous pool per modality, discarding the names that name-sensitive endpoints (e.g. rankings) depend on; (2) a single pool whose entries embed named `Text`/`Image`/`Audio`/`Video` objects, or `Image` objects carrying `uuids` (vLLM cache-reuse IDs) -- reachable from a single file or a single-key inline `records:` list, not just directory input. Batch sizes only apply to a single unnamed pool with unnamed entries.
+
+The directory case is caught up front, before the benchmark starts. The remaining shapes are only visible once the pool has been parsed, so they surface when the dataset is built.
+
+Batching does not preserve per-entry associations across modalities. If a pool entry pairs a specific text with a specific image, a batch size > 1 flattens each modality into an independent pool and samples from them separately, so the original text-image pairing is not preserved in the resulting request. Use `single_turn` instead of `random_pool` if exact pairing must be preserved.
+
+The `pool.jsonl` file above is text-only, so `--image-batch-size` would have no images to sample. A multimodal `random_pool` needs an `image` field in the pool entries:
+
+```bash
+cat > multimodal_pool.jsonl << 'EOF'
+{"text": "Describe what you see in this image.", "image": "https://example.com/img1.png"}

+### Stateful Chaining with `previous_response_id`
+
+Stateful chaining is **opt-in and driven by requesting storage**. Enable it with:
+
+```bash
+--extra-inputs '{"store": true}'
+```
+
+`store` is a *request* parameter, not a standard field of the Responses object,
+so AIPerf keys chaining off the storage you requested rather than off an echoed
+response field — the OpenAI spec does not include `store` on the response, and
+servers such as vLLM's agentic-api accept it on the request but never serialize
+it back. (If a server *does* echo `store: true` on the response object, that is
+honored too.)
+
+Some backends also require a server-side flag (e.g. vLLM with
+`VLLM_ENABLE_RESPONSES_API_STORE=1`) to actually persist responses. If the
+server does not persist a requested response, the next chained request fails
+against the missing `previous_response_id`; use a storing backend when enabling
+this feature.
+
+> **Startup requirement:** requesting `store: true` on `--endpoint-type responses`
+> is rejected at startup unless [`--use-server-token-count`](#server-token-counts)
+> is also set. Chaining sends only the newest turn on the wire, so client-side ISL
+> would undercount the server-side prompt; server-reported token counts are the
+> only accurate source. Add `--use-server-token-count`, or drop `store: true` to
+> keep sending the full history client-side.
+
+When chaining is active with `--endpoint-type responses`:
+- On **Turn 0**, AIPerf sends the initial prompt and captures the server-generated `response.id` (e.g. `resp_<hash>`) from the response object — because `store: true` was requested for the run.
+- On **Turn 1+**, AIPerf sets `previous_response_id: <resp_id>` and sends only the single newest turn in the `input` array rather than re-sending the entire accumulated conversation history.
+
+**Scope:** chaining is applied only in the default delta context mode
+(`deltas_without_responses`), where the newest turn is a genuine delta. The
+`*_with_responses` context modes carry full per-turn history and are left
+unchained to avoid sending the conversation twice.
+
+Chaining is also limited to the session-driven request path. Pre-encoded
+datasets (`--input-file` payloads sent verbatim) bypass session tracking, so
+their requests are sent exactly as authored and are never chained — author
+`previous_response_id` into those payloads yourself if you need it.
+
+The startup requirement above inspects the endpoint-level `--extra-inputs`. If
+`store: true` is instead supplied per turn (via a dataset row's `extra`),
+it cannot be seen at startup, but chaining still triggers the one-time runtime
+warning that client-side ISL undercounts the server-side prompt — enable
+`--use-server-token-count` in that case too.
+
+> **Input Sequence Length note:** because a chained turn only puts the newest turn
+> on the wire (the prior history lives server-side), the default client-side ISL
+> reflects just that turn and undercounts the prompt the server actually prefills.
+> Use [`--use-server-token-count`](#server-token-counts) for accurate multi-turn
+> ISL when chaining is enabled. AIPerf emits a one-time warning if chaining runs

 # Parameter Sweeps and Multi-Run Statistics
 
 Finding the optimal operating point for an inference server requires exploring a multi-dimensional space of concurrency, request rate, input lengths, and batch sizes. Rather than hand-tuning one variable at a time, parameter sweeps let you define the search space declaratively and let AIPerf run every combination, collecting statistically rigorous results for each.

+## Running Sweeps on Kubernetes
+
+`aiperf kube sweep` submits an `AIPerfSweep` CR that orchestrates parameter sweeps,
+multi-run confidence trials, and adaptive convergence on a Kubernetes cluster.
+The orchestration loop runs in a dedicated sweep-controller pod, not in the kopf
+operator.
+
+The local and Kubernetes paths share the same Config-v2 loader,
+`build_benchmark_plan`, `MultiRunOrchestrator`, and search-planner factory. The
+Kubernetes adapter preserves Jinja template leaves in the submitted CR, renders
+them per variation from the retained raw envelope, attaches the operator's
+`failurePolicy`, and executes each resulting `BenchmarkRun` through
+`K8sChildJobExecutor`. Operator-owned child tracking, status rollup, aggregate
+harvest, and result indexing remain outside the canonical planner.
+
+### Quick start: grid sweep over concurrency × rate
+
+`sweep.yaml`:
+
+```yaml
+benchmark:
+  models: [Qwen/Qwen3-0.6B]
+  endpoint:
+    urls: [http://server:8000/v1/chat/completions]
+    type: chat
+    streaming: true
+  datasets:
+    - name: main
+      type: synthetic
+  phases:
+    - name: profiling
+      type: poisson
+      duration: 120
+      concurrency: 8
+      rate: 10
+sweep:
+  type: grid
+  parameters:
+    phases.profiling.concurrency: [4, 8, 16, 32]
+```
+
+Submit:
+
+```bash
+aiperf kube sweep --config sweep.yaml --image aiperf:latest --total-workers 64
+```
+
+Preview the submitted resource with `--dry-run`. The JSON is written to stdout
+verbatim — never line-wrapped, whatever the terminal width — and includes the
+resolved `metadata.namespace` (from `--namespace`, or your kubeconfig
+context), so redirecting it to a file and applying it targets the same namespace
+as a live submission.
+
+Benchmark CLI flags override the matching Config-v2 YAML fields before the
+`AIPerfSweep` is submitted. When the input is an `AIPerfJob` manifest, kube
+deployment flags merge over its deployment settings; unrelated nested
+`podTemplate` fields are preserved.
+
+> Parameter keys are dotted paths rooted **inside** the `benchmark:` block,
+> so `phases.profiling.concurrency` is correct and the redundant
+> `benchmark.` prefix is rejected by the validator. A handful of bare names
+> (`concurrency`, `rate`, `requests`, `duration`, ...) are sugar for
+> `phases.profiling.<name>`. The one envelope-level escape is
+> `variables.<name>`, which rewrites the top-level Jinja `variables:` block
+> per variation.
+
+#### Credentials must remain fixed
+
+Kubernetes sweeps reject credential-bearing parameter axes before the
+sweep-controller or any child AIPerfJob is created. This includes API keys,
+tokens, passwords, credential-bearing URLs, every `endpoint.headers.*` axis,
+and credential-like `variables.*` names. The rule applies to grid, zip,
+scenario, adaptive-search, Sobol, and Latin Hypercube sweeps.
+
+Keep credentials fixed across every variation and inject them through the
+Secret-backed endpoint credential environment variables described in
+[RBAC and Security](../kubernetes/rbac-security.md). Safe endpoint URL axes remain
+supported when their values contain no userinfo or sensitive query parameters.
+Display redaction is a defense-in-depth boundary for legacy data, not a way to
+make secret sweep parameters safe.
+
+### What gets created
+
+1. One `AIPerfSweep` CR (the parent — `kubectl get aiperfsweeps`).
+2. One `JobSet` for the sweep-controller pod (which orchestrates the loop).
+3. One `AIPerfJob` CR per `(variation, trial)` pair, deterministically named
+   `<sweep>-v<idx:02d>[-t<trial:01d>]`. List them with
+   `kubectl get aiperfjobs -l aiperf.nvidia.com/sweep=<sweep-name>`.
+4. Per-child results under `<base>/<ns>/<sweep>-v07-t2/<child-epoch>/`.
+5. Sweep aggregate under `<base>/<ns>/sweeps/<sweep>/<sweep-epoch>/`
+   (`aggregate.json`, `children.json`, and a `sweep_aggregate/` directory).
+
+The sweep-controller initially writes child `sweep.json` backlinks on its
+ephemeral results volume. During aggregate commit, the operator recreates those
+backlinks on its PVC from the canonical `children.json` manifest before it
+publishes the aggregate or deletes the sweep-controller JobSet. Archived child
+lookups therefore continue to resolve their parent, variation, trial, and both
+run epochs after the child and parent CRs have been removed.
+
+The sweep controller owns the `(variation, trial)` expansion. It omits the
+parent `multiRun` block from each child AIPerfJob, so every child executes
+exactly one benchmark run instead of recursively repeating all trials.
+
+### Auto-plotting the parent aggregate
+
+The Config-v2 `plot:` field has the same meaning for `AIPerfSweep` as it does
+for an in-process sweep. Plotting runs once in the sweep-controller after
+cross-variation aggregation, not once in every child AIPerfJob. Generated
+plots and the materialized `.aiperf-plot-config.yaml` receipt are stored under
+`<base>/<ns>/sweeps/<sweep>/<sweep-epoch>/` and are harvested to the operator
+PVC with the other parent artifacts.
+
+The sweep aggregate ready marker is written only after plotting returns. An
+optional plot failure (`benchmark.artifacts.plotRequired: false`) is logged and
+the aggregate still becomes ready. A required plot failure
+(`plotRequired: true`) moves aggregation to failed and withholds the ready
+marker, preventing the operator from harvesting a partial completion. An
+explicit `benchmark.artifacts.autoPlot: false` suppresses plotting even when a
+`plot:` envelope is present.
+
+### Mode: independent vs repeated
+
+`spec.sweep.iterationOrder` (or `--parameter-sweep-mode` for in-process runs)
+selects the iteration order of variations and trials. Both produce the
+same total runs and the same `sweep_aggregate/` output — only the artifact
+path layout and submit order differ.
+
+| Mode (default `repeated`) | Iteration order | Artifact tree |
+|---|---|---|
+| `repeated`    | trials outer, variations inner | `<base>/profile_runs/trial_NNNN/<variation>/` |
+| `independent` | variations outer, trials inner | `<base>/<variation>/profile_runs/trial_NNNN/` |
+
+`repeated` (the default) is the right choice when absolute wall-clock timing across variations matters and you
+want to interleave variations within each trial — e.g. "run the whole
+sweep, then run it again". `independent` groups all trials of a single
+configuration in close temporal proximity, which gives tight confidence
+intervals per variation.
+
+Adaptive convergence (`spec.multiRun.convergence` / `--convergence-metric`) is
+incompatible with `repeated` and rejected at submit time — convergence
+needs to evaluate per-cell stability, which has no place to land in
+trial-outer iteration. Use `independent` for adaptive sweeps.
+
+### Multi-run confidence
+
+```yaml
+multiRun:
+  numRuns: 5
+  cooldownSeconds: 30
+```
+
+A parameter axis is optional. When `multiRun.numRuns > 1` is present without
+`sweep:`, `aiperf kube sweep` and `aiperf kube generate --operator` create an
+`AIPerfSweep` with one no-op `base` scenario. The canonical plan therefore has
+one unchanged configuration and five trials; it never collapses the request to
+one `AIPerfJob`. A config with no `sweep:` and the single-run default
+`multiRun.numRuns: 1` still generates an `AIPerfJob`.
+Hand-authored `AIPerfJob` resources must follow the same boundary: setting
+`multiRun.numRuns > 1` or `multiRun.convergence` is rejected at admission so
+the requested trials cannot be silently collapsed to one run.
+
+### Adaptive convergence (composes with sweep)
+
+```yaml
+multiRun:
+  numRuns: 10
+  cooldownSeconds: 30
+  convergence:
+    metric: time_to_first_token
+    stat: p99
+    minRuns: 3
+    threshold: 0.05
+    mode: ci_width
+```
+
+When `multiRun.convergence` is set, trials early-stop once the criterion fires
+(or `multiRun.numRuns` is hit, whichever comes first); the `numRuns` field
+remains the hard ceiling. `sweep` and `multiRun.convergence` compose freely:
+each cell of a grid sweep runs adaptive trials.
+
+For convergence without a parameter axis, the generated one-cell scenario uses
+independent iteration order so the controller can evaluate the completed cell
+after each trial and stop before the hard ceiling.
+
+### Adaptive search (Bayesian Optimization)
+
+When the search space is too large to grid-enumerate (e.g. concurrency
+1–1000) and a single scalar objective captures what you care about, use
+`sweep.type: adaptive_search` instead of `sweep.type: grid`. The sweep-controller
+pod instantiates the same `BayesianSearchPlanner` used in-process by
+`aiperf profile --search-*` and drives the loop one `AIPerfJob` per
+iteration; the kopf operator stays unaware of BO and just sees ordinary
+child create/delete events. The completed `search_history.json` is archived
+inside the parent sweep's run-epoch directory so histories from separate
+sweeps cannot overwrite one another. `status.totalVariations` and
+`status.maxTotalRuns` become upper bounds (early plateau convergence
+may terminate sooner), and the BO trajectory is logged incrementally to
+`search_history.json` so partial runs survive a crash or cancellation.
+Sobol and Latin Hypercube sweeps similarly archive `sampling_design.json`
+under the parent epoch's `sweep_aggregate/` directory; separate sweep runs
+therefore retain separate design audits on the shared operator PVC. Before
+the results-sidecar marks the bundle ready, the sweep controller removes the
+canonical orchestrator's temporary top-level run and aggregate directories.
+The operator harvests only `<namespace>/sweeps/<name>/<epoch>/`, so unrelated
+sweeps cannot overwrite shared-PVC root paths.
+
+See [Adaptive search on Kubernetes](../kubernetes/adaptive-search.md) for the full
+walkthrough — CR examples, status semantics, mutual-exclusion rules,
+operator-managed gate exception, cancellation behaviour, and on-disk
+layout. For the algorithm reference, see
+[Bayesian-Optimization Outer Loop](../sweeping/bayesian-optimization.md).
+
+### Cancel
+
+```bash
+kubectl patch aiperfsweep <name> --type merge -p '{"spec":{"cancel":true}}'
+```
+
+The sweep-controller pod observes `spec.cancel`, propagates it to the current
+child via `spec.cancel: true`, and after that child reaches a terminal phase,
+skips remaining variations and runs aggregation over completed children only.
+Child labels are discovery hints only: cancellation is authorized by the exact
+parent owner reference, sweep UID and run epoch, then applied with an immutable
+child-UID precondition so a same-named replacement cannot be cancelled.
+If the controller restarts after cancellation was already recorded, it performs
+a read-only recovery of terminal children before aggregation. Recovery requires
+the exact parent name, UID, and sweep-run epoch, does not create new children,
+and does not wait for non-terminal children. This preserves completed, failed,
+and cancelled child outcomes even though the restarted controller has a fresh
+`emptyDir`.
+
+### Resume after sweep-controller crash
+
+The sweep-controller pod is JobSet-managed: a crash restarts it, and idempotency
+uses deterministic child names, `ownerReferences`, and a reserved hash of each
+generated child execution contract. Terminal reads and result rollups recheck
+the immutable child UID, parent owner identity, and sweep run epoch before a
+child is credited. Grid sweeps therefore resume from the first non-existent
+child without re-running terminal ones. For Sobol and Latin
+hypercube sweeps, Kubernetes derives a stable sampling seed from the parent CR
+UID when `sweep.seed` is omitted; an explicit seed is preserved. Adaptive
+searches similarly derive a stable planner seed when `sweep.randomSeed` is
+omitted, then replay terminal child metrics through `ask()` / `tell()` in order.
+The first new proposal is made only after that planner history is reconstructed;
+an owned child whose contract hash is missing or different is rejected rather
+than silently reused. Once the epoch bundle has its ready marker, a controller
+restart validates the raw parent aggregate and republishes terminal status
+directly; it does not replay the planner or recreate temporary run artifacts.
+If the operator has already published its PVC-backed result reference, a late
+controller restart preserves that reference instead of replacing it with the
+ephemeral sidecar address.
+The controller's live status patch keeps `resultsAvailable: false`; the
+operator flips it to true only after every advertised file is durable on the
+results PVC. Parent TTL cleanup waits for that durable reference, including
+when `ttlSecondsAfterFinished` is zero.
+Sweep result retention does not depend on that parent CR remaining present.
+The durable `aggregate.json` stores the sweep's `resultsTtlDays`, and an
+operator background reconciliation removes expired epoch directories and
+their index rows, then repoints or removes `latest.txt`. Archives without an
+explicit value use the operator-level `AIPERF_RESULTS_TTL_DAYS` default.
+Local execution keeps its ordinary unseeded behavior.
+
+If the sweep-controller exhausts the JobSet retry budget before it can publish
+its own terminal status, the operator marks the owning `AIPerfSweep` Failed
+from the JobSet event. The fallback writes the same failure timestamps,
+`aggregation.phase`, and `resultsAvailable: false` shape as the controller's
+normal failure writer. Both the JobSet owner reference and the parent UID must
+match, and the status update is resource-version fenced, so a delayed event
+cannot fail a recreated same-named sweep or overwrite an already-terminal one.
+
+### Failure policy
+
+```yaml
+failurePolicy:
+  onChildFailure: continue       # default
+  maxFailures: 3                 # 0 = unbounded (default)
+```
+
+A failed child becomes a `failedRuns` count entry on the parent and the sweep
+advances to the next variation. Set `onChildFailure: abort` for stricter behavior.
+
+`status.failedRuns` counts only `Failed` and `PartiallyFailed` children;
+cancelled children are tallied separately under `status.runStates.cancelled`.
+The full per-phase breakdown lives at `status.runStates`
+(`pending` / `running` / `completed` / `failed` / `cancelled`). If you previously
+relied on `failedRuns` as a "did anything not succeed" signal, read
+`status.runStates` instead — `failedRuns` no longer includes cancelled
+children.
+
+### Schema invariants
+
+The apiserver rejects these before any pod is scheduled (CEL rules on the
+`AIPerfSweep` CRD):
+
+- `spec.sweep` is required on `AIPerfSweep` (use `AIPerfJob` for a
+  single benchmark).
+- `spec.sweep` and `spec.multiRun` are immutable after creation
+  (mutating them would corrupt the run-epoch ledger).
+
+These are enforced by Pydantic instead — client-side by
+`aiperf kube validate`, server-side by the operator on reconcile
+(`status.phase=Failed`). They cannot move to CEL because `spec.benchmark`
+is a preserve-unknown node:
+
+- `multiRun.convergence.minRuns <= multiRun.numRuns` — the convergence
+  criterion's minimum trials cannot exceed the multi-run hard ceiling.
+- `spec.benchmark.sweep` / `spec.benchmark.multiRun` are rejected as
+  unknown fields — the orchestration axes belong at the CR top level, not
+  on the per-child benchmark stamp.
+
+Full rule catalog: [CRD Validation Rules](../kubernetes/crd-validation.md).
+
+### Listing historical sweep runs
+
+The sweep aggregate is served by the operator's results server under
+`/api/v1/sweeps/<ns>/<sweep>/epochs/<epoch>/artifacts` (per-child results
+stay on the `AIPerfJob` route, `/api/v1/results/<ns>/<sweep>-v00-t1/`):
+
+```bash
+aiperf kube results <sweep-name>
+aiperf kube results <sweep-name> --run <epoch>
+```

+"""Tokenizer router -- serves tar+zstd of HF snapshot dirs from the shared cache.
+
+The api container has zero HF egress at request time. Snapshots are populated
+by the api container's own ``_prewarm_tokenizers`` (which runs before uvicorn
+binds), writing into the shared ``tokenizer-cache`` emptyDir mounted at
+``HF_HOME``. ``_prewarm_tokenizers`` then calls :func:`prewarm_bundle` for
+every configured name so the tar+zstd payload is fully materialised in this
+process's RAM before the port binds. The bundle endpoint then serves
+synchronously out of the module-level cache -- no per-request file IO,
+tarring, or compression in the hot path.
+
+If a request arrives for a name that prewarm did not cover (e.g. an out-of-band
+tokenizer the operator did not pre-register), the endpoint falls back to an
+on-demand build under a per-name lock so concurrent requests for the same name
+do not stampede. The per-request build keeps the same on-disk semantics as
+prewarm (resolve via ``snapshot_download(local_files_only=True)``, materialise
+via :func:`_materialize_bundle`), so cold-cache requests still succeed -- they
+just pay the materialisation cost on the request path instead of at startup.

+ *   - BentoML LLM Inference Handbook (TTFT as UX headline, Goodput as SLO health)
+ *   - vLLM production guide (p99 for tail SLOs, ITL for streaming smoothness)
+ *
+ * SLO policy: the dashboard only passes judgment against thresholds the USER
+ * declared via ``cfg.slos`` (same dict AIPerf's goodput feature consumes —
+ * e.g. ``--goodput "time_to_first_token:100 inter_token_latency:10"``).
+ * There are no hard-coded "industry defaults" here: if the user hasn't told
+ * us what good looks like for a given metric, we show the value without a
+ * status chip. This keeps the chip honest — green means *you* declared this
+ * SLO and the run met it, red means *you* declared it and the run missed it.
+ *
+ * Stat-selection rules:
+ *   - Throughput metrics → ``current`` (or ``avg`` fallback). p99 of a rate
+ *     is noise; the hero number is the sustained value.
+ *   - Latency metrics   → ``p99``. This is the tail guarantee customers
+ *     promise end-users; ``avg`` goes in the sub-line for context.
+ *   - ITL               → ``avg`` is the headline (streaming smoothness);

+			 * Inserts tokens _before_ another token in a language definition or any other grammar.
+			 *
+			 * ## Usage
+			 *
+			 * This helper method makes it easy to modify existing languages. For example, the CSS language definition
+			 * not only defines CSS highlighting for CSS documents, but also needs to define highlighting for CSS embedded
+			 * in HTML through `<style>` elements. To do this, it needs to modify `Prism.languages.markup` and add the
+			 * appropriate tokens. However, `Prism.languages.markup` is a regular JavaScript object literal, so if you do
+			 * this:
+			 *
+			 * ```js
+			 * Prism.languages.markup.style = {
+			 *     // token
+			 * };
+			 * ```
+			 *
+			 * then the `style` token will be added (and processed) at the end. `insertBefore` allows you to insert tokens
+			 * before existing tokens. For the CSS example above, you would use it like this:
+			 *
+			 * ```js
+			 * Prism.languages.insertBefore('markup', 'cdata', {
+			 *     'style': {
+			 *         // token
+			 *     }
+			 * });
+			 * ```
+			 *
+			 * ## Special cases
+			 *
+			 * If the grammars of `inside` and `insert` have tokens with the same name, the tokens in `inside`'s grammar
+			 * will be ignored.
+			 *
+			 * This behavior can be used to insert tokens after `before`:
+			 *
+			 * ```js
+			 * Prism.languages.insertBefore('markup', 'comment', {
+			 *     'comment': Prism.languages.markup.comment,
+			 *     // tokens after 'comment'
+			 * });
+			 * ```
+			 *
+			 * ## Limitations
+			 *
+			 * The main problem `insertBefore` has to solve is iteration order. Since ES2015, the iteration order for object
+			 * properties is guaranteed to be the insertion order (except for integer keys) but some browsers behave
+			 * differently when keys are deleted and re-inserted. So `insertBefore` can't be implemented by temporarily
+			 * deleting properties which is necessary to insert at arbitrary positions.
+			 *
+			 * To solve this problem, `insertBefore` doesn't actually insert the given tokens into the target object.
+			 * Instead, it will create a new object and replace all references to the target object with the new one. This
+			 * can be done without temporarily deleting properties, so the iteration order is well-defined.
+			 *
+			 * However, only references that can be reached from `Prism.languages` or `insert` will be replaced. I.e. if
+			 * you hold the target object in a variable, then the value of the variable will not change.
+			 *
+			 * ```js
+			 * var oldMarkup = Prism.languages.markup;
+			 * var newMarkup = Prism.languages.insertBefore('markup', 'comment', { ... });
+			 *
+			 * assert(oldMarkup !== Prism.languages.markup);
+			 * assert(newMarkup === Prism.languages.markup);
+			 * ```
+			 *
+			 * @param {string} inside The property of `root` (e.g. a language id in `Prism.languages`) that contains the
+			 * object to be modified.
+			 * @param {string} before The key to insert before.
+			 * @param {Grammar} insert An object containing the key-value pairs to be inserted.
+			 * @param {Object<string, any>} [root] The object containing `inside`, i.e. the object that contains the
+			 * object to be modified.
+			 *
+			 * Defaults to `Prism.languages`.
+			 * @returns {Grammar} The new grammar object.

+"""Accept ``KEY=VALUE`` and JSON on the ``aiperf kube`` mapping flags.
+
+``KubeOptions`` exposes four ``dict[str, str]`` flags -- ``--annotations``,
+``--labels``, ``--env-vars`` and ``--env-from-secrets``. cyclopts binds mapping
+fields by dot-notation (``--labels.tier gold``) and has no code path for a bare
+token, so ``--labels tier=gold`` reaches ``Argument._json`` carrying an empty
+``keys`` tuple and dies on ``token.keys[-1]`` with ``IndexError: tuple index out
+of range``. The defect is upstream and unfixed in both cyclopts 4.23.2 (the
+pinned release) and the 5.0.0b1 prerelease, so it cannot be resolved by a bump.
+
+Registering this module's hook as a cyclopts ``config`` callable places it after
+token parsing and before conversion -- the one point where the tokens are
+reachable and ``Argument._json`` has not run yet. Bare ``KEY=VALUE`` and
+JSON-object tokens are rewritten into the keyed tokens cyclopts expects, so both
+spellings work; anything else raises a usage error naming every accepted
+spelling instead of crashing.

+"""Fail-closed readiness markers for an exported results directory.
+
+The controller, the records manager, the operator's results API, and the
+Kubernetes results sidecar all agree on this on-disk contract: top-level result
+files stay hidden from consumers until ``write_ready_marker`` commits, and a
+crash mid-export leaves the processing marker behind so the directory reads as
+not-ready rather than partially-ready.
+
+This module is deliberately dependency-free (stdlib plus a lazily imported
+``orjson``). ``aiperf.kubernetes.results_sidecar`` imports the marker helpers
+it serves and adds the FastAPI/uvicorn server on top; importing that module
+for the marker contract alone would drag uvicorn, FastAPI, starlette and
+aiofiles into processes that never serve a request.

+"""Which CLI flags actually reach ``AIPerfConfig`` when ``--config`` is used.
+
+``resolve_config`` merges a YAML base with explicitly-set CLI flags, but it
+only knows how to route a subset of ``CLIConfig`` into the merged dict. Any
+flag outside that subset used to be discarded without a word: a user running
+``aiperf profile -f base.yaml --random-seed 42`` got a different seed than
+they asked for and no diagnostic. For a benchmarking tool that silently
+corrupts published numbers.
+
+``CLIConfig`` is the source of truth, and that is structural rather than a
+convention: ``resolve_config`` takes a ``CLIConfig`` and a path, and both
+``aiperf profile`` and ``aiperf service`` call it with nothing else. A flag
+can therefore reach ``AIPerfConfig`` only by being a field on ``CLIConfig``,
+which is what lets the classification test enumerate ``model_fields`` and
+claim completeness. Give ``resolve_config`` another source of user intent
+and that claim quietly stops holding -- extend the classification in the
+same change. (``aiperf service``'s own ``--service-id`` / ``--health-*``
+parameters live on the command, never reach this path, and are out of scope
+by construction.)
+
+This module makes the boundary explicit and enforceable:
+
+``ROUTED_UNDER_CONFIG``
+    Fields the resolver genuinely routes. Derived from the same maps the
+    resolver and converters use, so it cannot drift from them.
+
+``UNROUTED_UNDER_CONFIG``
+    Fields known to be dropped. Written out by hand on purpose -- a computed
+    complement would make ``test_every_section_field_is_classified`` vacuous.
+    A newly-added CLI flag lands in neither set and fails that test at
+    authoring time, which is the whole point.
+
+:func:`reject_unrouted_cli_flags` turns the drop into a ``ConfigurationError``
+naming the offending flags. Repairing the routing (so entries move from
+``UNROUTED`` to ``ROUTED``) is separate work; until then users get a loud
+error instead of a wrong benchmark.

+        rather than a fail-fast.
+
+        Three protections against false-positive batch expiry, all earned in
+        production at 285 worker-group managers where a controller stall
+        flagged 141 of them dead in the same millisecond:
+
+        1. Catch-up detection -- if the gap between consecutive ticks exceeds
+           ``HEARTBEAT_INTERVAL * HEARTBEAT_WATCHDOG_DELAY_FACTOR``, the watchdog
+           itself was delayed and every service looks stale through no fault of
+           its own. Skip the tick; the next one sees fresh heartbeats.
+        2. Consecutive-tick verification -- a service must appear stale on
+           ``HEARTBEAT_STALE_CONFIRMATION_TICKS`` consecutive ticks before being
+           failed. Worst-case detection at the defaults remains 20 seconds.
+        3. Liveness ground truth -- ``get_service_liveness`` is consulted before
+           reaping. Where the manager owns a real process handle (local
+           multiprocessing) a demonstrably-alive service is never reaped, so a
+           blocked event loop cannot be mistaken for a death. Under Kubernetes
+           it returns ``None`` and heartbeat inference stands unchanged.
+
+        Optional services (those absent from ``required_services``) are dropped
+        with a warning instead of being failed, matching the startup-time
+        contract in ``_reap_dead_processes_during_registration``.
+
+        Every exit path drains the reaped-service queue. A service reaped on a
+        previous tick is only handed to the controller by that drain, so an

+        Gating on the echoed response ``store`` therefore never fires against
+        those servers and silently disables chaining. We instead chain when
+        storage was requested via ``--extra-inputs store:true`` (endpoint
+        ``extra``); a server that *does* echo ``store: true`` is honored too.
+        When neither is set we return ``None`` so the caller falls back to
+        sending the full history.
+
+        The response object lives under ``response`` for streaming lifecycle
+        events (``response.created`` / ``response.completed`` / ...) and at the
+        top level for a non-streaming response body.
+
+        A request that returns HTTP 200 but fails does not set
+        ``RequestRecord.error``. Streaming signals this via a
+        ``response.failed`` / ``response.incomplete`` event; a non-streaming
+        body signals it via top-level ``status``. In either case the advertised
+        id belongs to an aborted response, so chaining onto it would corrupt the
+        next turn and we return ``None`` regardless of the advertised id.

+"""Benchmark-metric heuristics over an AIPerfJob's ``.status``.
+
+These detectors are the salvaged half of the removed ``aiperf kube watch``
+diagnosis engine. The pod-level checks it also carried (crash loop, OOM,
+pending-too-long, ImagePull) are not reproduced here.
+
+The operator does not run the retired ``watchdog_*`` stack. Its monitor handler
+does independently reconcile pod startup blockers: container waiting states
+and PodScheduled=False/Unschedulable conditions become durable CR status and
+warnings, with conservative terminalization for stable non-recoverable states.
+This module stays focused on benchmark metrics and does not duplicate that pod
+inspection.
+
+What is *not* duplicated anywhere else is the benchmark-metric view: error
+rate, tail-latency skew, and a throughput-aware notion of "running but making
+no progress". ``WatchdogDataSource`` only sees pods, events, nodes and
+cpu/memory, so it cannot compute any of these.
+
+Pure functions over the raw CR ``status`` dict: no Kubernetes client, no I/O,
+no model layer. That keeps them trivially testable and lets any caller that
+can fetch an AIPerfJob feed them.

+    total the export and console report — using ``request_count`` alone would
+    undercount by every failed request.
+
+    ``completed_request_count`` is that same sum computed upstream, and it is
+    preferred because it is the only total that survives the live path.
+    ``error_request_count`` carries ``MetricFlags.ERROR_ONLY``, which
+    ``records_manager_processing.filter_display_metrics`` strips before anything
+    reaches ``status.liveMetrics`` or ``/api/metrics``, so on a running job the
+    sum would silently lose every failed request.
+
+    ``error_rate`` is the fraction (0..1) of that grand total that failed.
+    When the authoritative ``request_error_rate`` metric tag (a percent,
+    ``100 * errors / total``) is present it is mirrored verbatim (``rate/100``)

+    completed runs. A fully-failed run (``request_count`` absent, only
+    ``error_request_count`` present) still reports its total and a 1.0 error
+    rate. A counter that is *absent* contributes 0; a counter that is *present

+"""Transient-fetch-failure retry gate for the completion handler.
+
+Closes the ``CompletedBeforeMonitor -> ResultsFetchFailed`` race documented
+in ``tests/kubernetes/audit/cases.py``. Sub-second benchmarks let the
+controller's post-export shutdown race the operator's HTTP fetch — the
+readiness marker and key files exist on the controller PVC, but the
+operator hits a connection-refused or empty results listing as the
+controller container terminates.
+
+Strategy: when the fetch result has the race signature (``has_error`` set,
+no key result files), and the completion claim is still fresh, raise
+``kopf.TemporaryError`` BEFORE the caller writes terminal status. The
+orphan-claim recovery path
+(``monitor.py::_recover_orphaned_completion_claim``) re-runs
+``handle_completion`` on the next monitor tick because the CR remains
+non-terminal but the claim annotation is durable. The retry is bounded by
+the ``RESULTS.TRANSIENT_FETCH_RETRY_BUDGET_SEC`` setting (wall-clock from
+the claim timestamp) so a permanently-broken controller still progresses

+# How long a completion claim is allowed to suppress a failure stamp.
+#
+# ``Annotations.COMPLETION_CLAIMED`` is stamped on the CR's *metadata*, which is
+# writable by anyone who can edit the AIPerfJob — ``client_cache`` calls the
+# annotation untrusted for exactly this reason. Trusting it without bound lets a
+# forged (or simply orphaned) value permanently disable ``spec.timeoutSeconds``
+# enforcement and the "JobSet not found" FAILED stamp, so a job can hang forever
+# with no terminal phase. The claim's legitimate purpose is narrow — it covers
+# the window where the success branch owns the CR and is still draining results
+# — so bound the trust to that window and treat an older or unparsable claim as
+# no evidence at all.
+#
+# The window is deliberately absolute rather than derived from
+# ``spec.timeoutSeconds``. Every ``try_claim_completion`` call site stamps the
+# claim only AFTER completion evidence (controller benchmark-complete
+# annotation, terminated control-plane container, or key export files already
+# on the PVC), so a live claim means the benchmark is done and the deadline is
+# moot; what remains is result draining, whose cost tracks artifact size, not
+# the benchmark deadline. Scaling the window down to a 30 s ``timeoutSeconds``
+# would therefore stamp FAILED over succeeded-but-still-draining runs — the
+# exact bug this gate exists to prevent. A handler that crashes after claiming
+# does not wait out this window either: ``_maybe_recover_orphan_claim`` runs
+# ahead of ``_check_job_timeout`` on every tick and re-drives
+# ``handle_completion`` as soon as ``_benchmark_appears_complete`` agrees.

+Handles AIPerfJob CRD lifecycle with:
+- Spec validation and endpoint health checks
+- Kubernetes event emission
+- Condition tracking (ConfigValid, EndpointReachable, ResourcesCreated, etc.)
+- Metrics summary extraction
+- Results storage with retry logic
+- Job cancellation support
+- Job timeout detection
+- Pod restart monitoring
+- Results TTL cleanup
+
+Run: kopf run -m aiperf.operator.main --verbose

+Handler categories dispatched below, in order: startup (configure),
+lifecycle (on_create / on_delete / on_cancel / on_benchmark_complete),
+resource watches, and bounded timers (heartbeat_watchdog, cleanup_old_results).
+
+All kopf decorators live here so handler modules stay decorator-free

+"""Prometheus metrics for the AIPerf kopf operator.
+
+Exposes a /metrics HTTP endpoint on a dedicated port (default 9090) so cluster
+operators can scrape reconcile latency, error rate, and per-handler outcome
+counts without going through the FastAPI sidecar (which runs in a separate
+container and cannot see the kopf process's in-memory state).
+
+Metrics:
+    aiperf_operator_handler_duration_seconds{handler}      Histogram
+    aiperf_operator_handler_total{handler, outcome}        Counter
+        outcome ∈ {success, retry, fatal, error}
+        - success: handler returned normally
+        - retry:   raised kopf.TemporaryError (kopf will retry)
+        - fatal:   raised kopf.PermanentError (kopf stops retrying)
+        - error:   any other exception, incl. CancelledError/KeyboardInterrupt/SystemExit
+    aiperf_operator_completion_claim_races_total           Counter
+        Incremented each time try_claim_completion decisively loses the race
+        for a CR: the annotation is confirmed present on a live re-read,
+        either because the body snapshot already showed it or because the
+        atomic test-and-add patch conflicted with 409. A 422 rejection is
+        retried rather than counted, so it does not increment this.
+
+Usage:

+
+A cluster-wide operator runs with ``--all-namespaces``, so without a claim it
+also reconciles namespaces that host a scoped operator, and two operators fight
+over the same AIPerfJob. Ownership here follows the install, not the job:
+
+- A scoped operator (``AIPERF_OPERATOR_ID`` set) writes a
+  ``coordination.k8s.io/v1`` Lease named ``aiperf-operator`` into every
+  namespace it watches, and renews it on a timer.
+- Every operator, the global one included, skips a namespace whose Lease is
+  held by a different identity and still fresh.
+- The global operator (``id == ""``) never writes a Lease. It owns every
+  namespace with no live claim.
+
+The lease duration is deliberately long (minutes, not seconds): a
+crash-looping operator should keep its namespace across restarts, and only an
+uninstall should let the claim lapse.

+        the global operator re-lists every claim so a namespace whose scoped
+        operator went away falls back to it.
+
+        A renewal that lapsed for longer than the lease duration lets a rival
+        operator legitimately take over, so each renewal first re-reads the
+        Lease. A namespace now held by someone else *and still live* is dropped
+        rather than stolen back: an unconditional patch would silently
+        double-reconcile it. A rival whose own lease has since expired is a
+        different story -- the namespace is unowned again, so re-acquire it
+        instead of abandoning it forever.

+
+    This client connects to the controller pod's HTTP API to retrieve
+    real-time progress information during job execution. Includes retry
+    logic with exponential backoff for transient failures.
+
+    All public methods require the client to be entered as an async context
+    manager; calling them outside of ``async with`` raises ``RuntimeError``.
+
+    controller_host format:
+        Every public method takes a ``controller_host`` string. In-cluster
+        this is the fully qualified headless-service DNS name produced by
+        :func:`aiperf.kubernetes.jobset.controller_dns_name`, of the form
+        ``<jobset>-controller-0-0.<jobset>.<namespace>.svc.cluster.local``
+        (the leaf ``controller-0-0`` is the single controller replica's
+        JobSet pod DNS). When port-forwarding from outside the cluster,
+        ``localhost`` or any reachable IP/hostname is also accepted.
+
+        When :attr:`K8sEnvironment.CONTROLLER_HTTP_URL_OVERRIDE` is set
+        (chaos tests only), controller API-port requests ignore
+        ``controller_host`` and go to the override URL instead. Sidecar-port
+        clients still use direct pod DNS so salvage can bypass API-port faults.
+        See :meth:`_base_url`.
+
+    Example:
+        >>> async with ProgressClient() as client:
+        ...     progress = await client.get_progress(
+        ...         "run-1234-controller-0-0.run-1234.aiperf.svc.cluster.local"

+"""Standalone HTTP server for serving stored benchmark results from the operator PVC.
+
+Runs as a sidecar container alongside the kopf operator, sharing the results
+PVC volume.
+
+**This app is the operator Pod's only FastAPI app.** Every ``/api/v1/*`` router
+-- jobs, sweeps, results, config, admin, analytics, dashboard_proxy -- mounts
+here, not on the operator container, which stays pure kopf and exposes only
+kopf's own ``/healthz`` plus the Prometheus metrics port. New HTTP surface goes
+here by default.
+
+Honest note on provenance: that split is enforced by the chart and restated in
+the agent instruction files, but no commit, spec, or design doc in the
+subsystem's history ever argues for it -- it is only ever stated. The mechanism
+visible in the code is that kopf owns the operator container's event loop and
+its liveness endpoint, so a second ASGI server there would contend with it;
+treat that as the likely driver rather than the recorded one. Anyone with cause
+to revisit the split should know they are not overturning a written decision.
+
+Provides two layers:
+
+1. **File serving** - download raw result files with zstd content negotiation
+2. **Analytics** - SQLite-backed query endpoints (via ``runs_index``) for
+   leaderboards, history, and cross-job comparisons.
+
+Endpoints:
+    GET /healthz                                        - health check
+
+    File serving (``aiperf.operator.routers.results_files``). Every read of an
+    actual artifact is epoch-pinned; the unpinned job-level paths exist only to
+    reject the request and tell the caller to pin a run:
+    GET /api/v1/results                                          - list all jobs
+    GET /api/v1/results/{namespace}/{job_id}/runs                 - list a job's runs
+    GET /api/v1/results/{namespace}/{job_id}/runs/{epoch}         - list files for a run
+    GET /api/v1/results/{namespace}/{job_id}/runs/{epoch}/{file}  - download a file
+
+    Analytics (``aiperf.operator.routers.results_analytics``):
+    GET /api/v1/analytics/leaderboard                   - rank runs by metric
+    GET /api/v1/analytics/history                        - metric over time
+    GET /api/v1/analytics/compare                       - compare specific jobs
+    GET /api/v1/analytics/summary/{namespace}/{job_id}   - full summary for a job
+
+    Config (``aiperf.operator.routers.config``):
+    GET /api/v1/config/retention                         - current retention policy

+"""WebSocket proxy from the operator UI to per-job controller pods.
+
+Browsers viewing ``#/jobs/{ns}/{name}`` cannot reach the controller pod's
+``:API_SERVICE/ws`` endpoint directly — controller services are headless
+and intra-cluster. The operator already serves the UI and already knows
+the routing (it watches the AIPerfJob CR for ``status.jobSetName``), so it
+hosts a thin pass-through endpoint:
+
+    WS /api/v1/jobs/{namespace}/{name}/ws
+
+On connect: the proxy reads the CR's ``status.jobSetName``, derives the
+controller pod's headless-service DNS, opens an upstream WebSocket via
+``aiohttp``, and pumps frames in both directions until either side closes.
+
+The proxy is intentionally transparent — it does not subscribe on behalf
+of the client. The browser owns the subscribe protocol the controller
+exposes (``{"type": "subscribe", "message_types": [...]}``); see
+``src/aiperf/operator/ui/lib/job-ws.js`` for the canonical client behavior.

+"""SQLite-backed index of runs and sweep variations.
+
+Single-writer model: only the operator's kopf-owning process writes; readers
+(operator FastAPI workers, results-server sidecar) open the DB read-only.
+The single-writer assumption matches the operator's existing single-replica
+deployment and the completion-claim mechanic in ``client_cache.py``. If the
+operator is ever scaled up, only the kopf-owning process must call write APIs.
+
+The DB lives at ``<RESULTS.DIR>/.aiperf_index.sqlite`` in WAL mode. WAL mode
+gives us non-blocking readers across processes. All write APIs share the single
+module connection, so concurrent in-process writers (kopf runs per-object
+handlers concurrently) are serialized through ``_write_lock``: ``BEGIN
+IMMEDIATE`` cannot be entered twice on one connection, and an autocommit write
+must never be absorbed into another coroutine's open transaction. ``busy_timeout
+=5000`` only covers cross-process contention on the WAL.
+
+The index is a cache, never a source of truth. Every read site falls back to
+a filesystem scan on miss and lazy-backfills the row in the background, so a
+corrupt or stale index degrades to slower, never wrong.
+
+Index-only reads additionally require a completed-bootstrap marker and no
+pending result publication markers. A nonempty query result cannot itself
+prove that every ready run on the PVC is represented in SQLite.

+ *
+ * Ported from ``api/static-v2/components/realtime-metrics.js`` and adapted
+ * to the operator's REST snapshot shape:
+ *
+ *   - Input ``summary`` is an object keyed by metric tag:
+ *       ``{ [tag]: { avg, p1, p10, p50, p90, p95, p99, std, min, max, ... } }``
+ *     (no streaming ``current`` — the operator polls).
+ *   - Input ``slos`` is the user's declared ``cfg.slos`` dict from the CR
+ *     (``spec.benchmark.slos`` / ``spec.slos``), keyed by metric tag.
+ *   - Input ``timeseries`` is optional; when present, a per-tag array of
+ *     ``{t, values}`` samples drives sparklines. Empty by default until a
+ *     WS feed is wired up — sparkline placeholders render unobtrusively.
+ *
+ * SLO policy: only chip metrics where the user declared a threshold.
+ * Direction: latency-style ``<=`` by default; the throughput-side tags in
+ * ``LARGER_IS_BETTER_SLO_TAGS`` flip to ``>=`` (mirrors ``MetricFlags``
+ * server-side and matches the existing SLACompliance card on this page).

+ * Collapse a single normalized server-metrics snapshot into one number per
+ * KPI id whose underlying metric resolved to a finite value (including
+ * zero). Used by the per-job WS layer to push one sample per scrape into a
+ * per-KPI rolling buffer.
+ *
+ * This is intentionally more permissive than `curateServerMetrics`:
+ * `curateServerMetrics` may suppress some tiles when the current snapshot
+ * is all-zero (specifically `requests-waiting`, gated on
+ * `(waitingPeak ?? waitingAvg) > 0`), but the aggregator emits the
+ * zero-sample so the rolling buffer stays continuous. A queue going
+ * 5 -> 3 -> 1 -> 0 -> 0 -> 2 must keep its zero entries in the buffer so
+ * the sparkline renders the full trend; Task 2 extends the curator's tile
+ * gate to use the buffer instead of just the current snapshot.
+ *
+ * The latency tile id flips between `'p99-ttft'` and `'p99-e2e-latency'`
+ * depending on which histogram is present in the snapshot; the resolved id
+ * is returned alongside the values so the WS layer can key its buffer
+ * consistently.
+ *
+ * Note: the latency value is returned in seconds (the raw histogram unit);
+ * the curator multiplies by 1000 for display. Keep the buffer in seconds
+ * and let the rendering layer scale on read.
+ *

+ *   - ``summary``: ``{ [tag]: {avg, p99, current, ...} }`` — last-seen stats
+ *     per metric, mirroring the REST snapshot shape so callers can swap in
+ *     live data without reshaping.
+ *   - ``timeseries``: ``{ [tag]: [{t, values}, ...] }`` — bounded rolling
+ *     window for sparklines (~2 minutes / 120 points).
+ *
+ * Browser owns the subscribe protocol (controller speaks
+ * ``{"type":"subscribe","message_types":[...]}``). The proxy is transparent.

+ * COMPARE-EPOCHS - side-by-side diff of two epoch-pinned summaries for the same job.
+ *
+ * Route: ``/compare/<ns>/<name>/<epoch-a>/<epoch-b>`` (parameterized).
+ *
+ * Fetches both sides in parallel through ``api.fetchRunSummary``, which hits the
+ * run-specific ``/runs/<epoch>/profile_export`` alias rather than a literal
+ * filename: the alias resolves whatever summary name that run's persisted config
+ * selected (so custom export prefixes work) and falls back to the ``.zst``
+ * companion, decompressing it server-side. A non-2xx arrives as an ``Error``
+ * with ``.status`` attached, so a 404 (no summary on disk for that epoch) is
+ * distinguishable from a transport failure.
+ *
+ * Renders a nine-row table. The Delta column carries a sign-aware colour cue -
+ * green when the change direction matches the "better" direction for that
+ * metric, red when worse, gray when the absolute delta is under 1 percent. When
+ * one run lacks a summary (legacy flat layout), that column surfaces ``n/a``
+ * rather than failing the whole view.
+ *
+ * Same job name does not mean same experiment: re-running an edited spec
+ * produces a new epoch under the same name. The better/worse colouring is a
+ * regression claim, so it is withheld unless ``configDrift`` confirms both
+ * epochs used the same load-defining parameters (model, endpoint, dataset
+ * shape, per-phase concurrency/rate/count). Drift, or a run that exported no
+ * config at all, downgrades the deltas to plain uncoloured numbers plus a
+ * banner naming what changed.
+ *
+ * Scope: the nine metrics enumerated in ``METRICS`` below. No multi-metric
+ * expansion, no >2-run support, no statistical-significance testing - the
+ * operator's compare-epochs page is intentionally small.
+ *
+ * Distinct from ``pages/compare.js`` (multi-job analytics compare); the two
+ * share the ``/compare`` URL prefix but are dispatched on URL shape in
+ * ``app.js``.

+ * `parseVariationValues` maps it to chips, and
+ * `components/sweep-winner-summary-helpers.js` `formatTrialValues` delegates to
+ * the former. There were three parallel implementations and they disagreed --
+ * on the truncation marker, on nested objects, on nulls, on lists, and on
+ * unparseable strings -- so a guard added to one silently did not apply to the
+ * others. Every guard now lives here exactly once.
+ *
+ * Adaptive planners label variations `search_iter_NNNN` -- that string is the
+ * cell identity used for artifact paths, so it can't be renamed, but on its own
+ * it says nothing about what was actually tried. The parameter values are what
+ * a reader wants: `concurrency=17`, not `search_iter_0008`.
+ *
+ * Accepts the JSON-string form the CR carries (`status.runs[].values`, the
+ * children manifest's `variation_values`, and the child CR's
+ * `aiperf.nvidia.com/variation-values` annotation all use it) or an
+ * already-parsed object. Dotted dimension paths are shortened to their leaf
+ * (`phases.profiling.concurrency` -> `concurrency`) because the prefix is
+ * identical across every variation and only costs width.
+ *
+ * Returns `[]` -- never a partial descriptor -- for each of:
+ *
+ *   - Unparseable input. The writer only ever emits `orjson.dumps(...)`
+ *     (sweep_controller/k8s_executor.py:188-192), so a string that fails
+ *     `JSON.parse` is a corrupted or hand-edited annotation, not a descriptor.
+ *     A JSON object truncated mid-encode would otherwise surface its fragment
+ *     (`{"phases.profiling.conc`) as the page headline, because callers LEAD
+ *     with this label and demote the real `variation_label` beneath it.
+ *   - The writer-side truncation marker (`__aiperf_truncated__`, emitted when
+ *     the encoded values exceed the annotation/status byte budget). Rendering
+ *     `limitBytes=256, reason=...` as if it were a swept parameter would be
+ *     worse than showing the planner id.
+ *   - Null values. A key whose value is absent describes nothing; emitting
+ *     `concurrency=` or `concurrency=undefined` is the half-formed label this
+ *     helper exists to avoid.
+ *   - Nested objects and lists. Neither has a compact honest rendering on one
+ *     line, and an elided blob (`tuning={...}`) looks authoritative while
+ *     saying nothing.
+ *
+ * Same rule as the Python download-progress renderer,

+
+        Race-aware refresh: when both ``status.summary`` AND ``status.runEpoch``

+        primary AND fallback see empty state. The grace is

+        fallback below cannot run at all without ``status.runEpoch``. The loop
+        exits the instant either field lands, so only a genuinely stuck
+        completion pays the full wait.
+
+        ``status.summary`` mixes JsonMetricResult-shaped per-tag dicts with

+
+        Hits ``{AIPERF_OPERATOR_BASE_URL}/api/v1/results/{ns}/{name}/runs/{epoch}/profile_export``.
+        BASE_URL points at the results-server container (port 8081 in the
+        chart) — that's the only container in the operator Pod that hosts
+        ``/api/v1/*`` routers; the operator container on port 8080 has only
+        kopf health/metrics. Skips the call when the child has no
+        ``status.runEpoch`` yet.
+
+        Note on ``runEpoch`` semantics: ``set_run_epoch`` is invoked from
+        ``_record_results_on_status`` only when ``has_files=True`` — so
+        Failed / Cancelled children (which by definition have no results
+        files) NEVER carry ``runEpoch``, and that's correct: the fallback
+        has nothing to fetch. The other case ``runEpoch`` may be unset is
+        the transient ``phase=Completed`` window before the operator's
+        next reconcile stamps the epoch label; the orchestrator's outer
+        retry loop covers that race naturally. Without an epoch the URL
+        would be 422-rejected by the operator's epoch allowlist (regex
+        ``^\\d{9,10}(\\d{6})?$``), so short-circuiting is also safer than
+        synthesizing ``latest``.
+
+        Returns the projected ``dict[str, JsonMetricResult]`` shape on
+        success (same shape as ``_pull_summary_metrics``), or ``{}`` on any
+        failure (operator unreachable, file 404, parse error). Failure is
+        non-fatal: callers treat empty as "metrics unrecoverable" and fall
+        through.
+
+        Why not the child's results-sidecar? The operator deletes the
+        child JobSet on success (``_maybe_delete_jobset_after_success``),
+        which tears down the controller pod and its sidecar. Any in-flight
+        fallback then hits ``Connect failed`` or ``Name or service not known``
+        and loses the metrics. The operator's PVC-backed API is the durable
+        alternative — same JSON, no race.

+"""Status patches for AIPerfSweep fields owned by the sweep-controller pod.
+
+The operator owns: totalVariations, runEpoch, runtimeRef, lastChildEvent,
+conditions[Progressing/Cancelling], and the non-terminal ``phase``
+transitions (``Pending`` at create from kopf, ``Aggregating`` from the
+rollup once every child is terminal). The rollup also maintains live
+``completedRuns``, ``failedRuns``, and ``runStates`` during the run;
+the sweep-controller overwrites these with authoritative terminal values
+in ``aggregation_complete`` (see below).
+
+The sweep-controller owns: currentCell, aggregation, aggregateRef,
+aggregate, and the **terminal** ``phase`` transitions (any member of
+``PARENT_TERMINAL_PHASES`` written from ``aggregation_complete`` after the
+final exporters run). At terminal time it also overwrites ``completedRuns``,
+``failedRuns``, and ``runStates`` with the authoritative values from the
+on-disk parent aggregate, so these fields are correct even when the
+kopf rollup handler did not fire for every child (e.g. fast clusters
+where children terminate before the field-watch event is processed).
+
+``status.phase`` is therefore co-written by three managers. The rollup
+serializes its phase write through a JSON-patch ``test`` op
+(``handlers/sweep/child_rollup._conditional_phase_set``) so a concurrent
+terminal write from this writer is never clobbered: the apiserver test
+fails, the rollup's phase write is dropped, and the terminal phase
+stands. Every controller-pod write first tests the immutable parent UID, so a
+pod left behind by delete/recreate cannot patch the replacement sweep.
+
+Each writer applies with a distinct ``field_manager`` metadata string. The
+controller uses JSON Patch when a parent UID is available and retains the
+merge-patch path for compatibility with UID-less callers. Server-Side Apply
+was tried and reverted: SSA's
+relinquishment semantics caused a single field manager re-applying to
+drop its own previously-set fields between writer methods (e.g.
+``aggregation_running`` would erase ``currentCell``).

+In Kubernetes deployments, TimingManager (controller pod) and Workers (worker pods)
+run on different machines with potentially different clocks. This module tracks the
+clock offset between them using credit timestamps as a synchronization signal.
+
+Each credit carries ``issued_at_ns`` (controller wall clock). When the worker receives
+the credit, it computes ``sample = T2 - T1`` where T2 is the worker's wall clock.
+Because this is a one-way measurement, every sample includes network transit time
+as positive bias: ``sample = clock_skew + network_transit``.
+
+Minimum offset filtering (inspired by NTP's clock filter algorithm, RFC 5905) takes
+the smallest sample in a sliding window. The minimum has the least network delay,
+but it is still ``clock_skew + min_transit``, not the skew: min-filtering makes the
+transit term SMALL, never zero.
+
+That residual transit is removed separately. A pre-flight RTT measurement (ping/pong
+probes echoed verbatim by the credit ROUTER) yields ``estimated_one_way_ns =
+min_rtt // 2``, and ``correction_ns`` -- the value actually applied to timestamps --
+is ``offset_ns - estimated_one_way_ns``. Without that second term the correction
+shifts every worker timestamp EARLIER than true controller time by one one-way hop,
+which directly understates ``credit_to_start_latency`` (``request_start_ns -
+credit_issued_ns``), the very quantity that hop belongs to. On TCP loopback the
+uncorrected bias measures ~17us against a ~20us one-way estimate; cross-pod in a
+cluster both scale by two to three orders of magnitude, to the same order as the
+metric itself.
+
+The estimate assumes path symmetry and is measured on an idle channel at startup,
+so it is not exact -- it slightly overshoots when router turnaround dominates and
+undershoots under load. It is applied anyway because the uncorrected value carries a
+guaranteed one-directional bias, whereas the residual is smaller and unsigned. When
+no baseline RTT was established (all probes timed out), ``correction_ns`` falls back
+to the raw ``offset_ns`` -- the transit term is then unknown, not zero.
+
+Both the controller (CreditIssuer) and this tracker use a dual-clock bootstrap pattern:
+capture ``time.time_ns()`` once at startup as a wall-clock anchor, then derive all
+subsequent timestamps from ``time.perf_counter_ns()`` deltas. This makes both sides
+immune to NTP step corrections during the benchmark while keeping timestamps in the
+wall-clock domain for cross-machine comparison.

+    """Tracks clock offset between controller and worker using minimum offset filtering.
+
+    Uses a sliding window of recent offset measurements and selects the minimum
+    as the best estimate of ``clock_skew + one_way_transit``. This rejects network
+    jitter (which only adds positive bias) rather than averaging it in. The
+    surviving transit term is then removed using the pre-flight baseline RTT; see
+    ``correction_ns``, which is the value callers should apply.
+
+    Min filtering is asymmetric under drift: a *falling* true offset is picked up on
+    the very next sample, but a *rising* one is only tracked once the window fully
+    evicts the stale low sample -- up to ``window_size`` credits. A worker receiving
+    credits slowly therefore holds a stale-low offset for that period, which biases
+    corrected latencies high. Sub-second at normal credit rates; shrink
+    ``window_size`` if a deployment sees sustained one-directional drift.
+
+    That same asymmetry is why samples are screened before they enter the window:
+    a minimum estimator gives a single spuriously low sample authority over the
+    correction until the window evicts it. Two gates run in ``observe``: an
+    absolute plausibility bound, and rejection of samples sitting more than
+    ``outlier_factor`` median absolute deviations below the window's median. A
+    run of ``reset_after_rejects`` consecutive rejections is read as a real
+    downward step (controller restart, NTP step) and re-seeds the window.
+
+    Timestamps are derived from a wall-clock anchor captured once at initialization
+    plus ``perf_counter_ns`` deltas, matching the pattern used by the controller's
+    ``CreditIssuer``. This avoids sensitivity to NTP step corrections mid-benchmark.
+
+    ``measure_baseline_rtt`` is re-entrant: the Worker re-runs it periodically so
+    the one-way transit estimate follows a path that changed mid-run instead of
+    being frozen at the startup value for the rest of the benchmark.

+"""Readiness probe for the credit-RETURN half of the dual-channel credit protocol.
+
+Credits are dispatched controller -> worker on ROUTER/DEALER
+(``CommAddress.CREDIT_ROUTER``) and returned worker -> controller on a separate
+PUSH/PULL fan-in (``CommAddress.CREDIT_RETURN``). The two sockets come up
+independently -- the router binds ROUTER before PULL, and each worker connects
+each socket on its own schedule -- so a DEALER that has handshaked proves
+nothing about the PUSH side. A worker that announces ``WorkerDispatchable`` off
+DEALER liveness alone can therefore be routed credits it has no way to return.
+
+``IMMEDIATE=1`` is what makes the probe meaningful: libzmq refuses a send with
+``zmq.Again`` while no peer pipe exists, and accepts it the moment one does. So
+a single NOBLOCK send is a direct test of "is there a live connection to the
+PULL fan-in", with no reply needed from the router -- which matters because
+PUSH/PULL is unidirectional and the router has no way to answer.
+
+:class:`BaseZMQClient` sets IMMEDIATE globally, but deliberately *after*
+connect() where it is a documented no-op for ordinary clients (see
+``zmq_base_client.py``); only the credit-return PUSH client gets it pre-connect,
+and only because its one caller (:mod:`aiperf.workers.worker`) passes
+``socket_ops={zmq.IMMEDIATE: 1}`` explicitly at construction. This probe
+therefore verifies IMMEDIATE is actually 1 on the socket before relying on it --
+a caller that forgets that override would otherwise get a probe that always
+reports success on the first attempt (the connect-time pipe buffers the frame
+regardless of a live peer), silently defeating the exact stall it exists to
+catch.
+
+The probe frame is a real ``WorkerConnected``: the router already handles it on
+the PULL path (idempotently, as set insertion), and sending it here is what
+finally makes the message truthful -- it announces that the *return* path is
+connected, which the DEALER copy never established.

+    function, they only register).

+  - Decoration order: ``@kopf.*`` wraps OUTSIDE ``@track_handler`` for every
+    decorated handler in main.py. (Wrong order = kopf's kwargs filtering
+    breaks track_handler's call.)

+The metrics scrape uses an ephemeral port + ProxyHandler({}) per the

+"""Deterministic Rich console sizing for tests that assert on rendered output.
+
+`Console.size` short-circuits to the explicit dimensions only when *both* width
+and height were supplied. Width alone falls through to size detection, whose
+first branch hard-codes 80x25 for a dumb terminal — so under `TERM=dumb` (CI
+logs, non-interactive agent shells) `Console(width=120)` silently renders at 80,
+as does `console.width = 200` on a shared console and a `COLUMNS` override,
+which that branch returns before ever reading. The same tests render at the
+requested width under `TERM=xterm`, so assertions on table text pass on a
+developer machine and fail in CI, or the reverse, with Rich wrapping or
+ellipsizing cells at a width nobody chose.
+
+Pin both dimensions through these helpers instead of sizing consoles inline.

+"""Integration test: same-named AIPerfJob resubmit preserves prior results.
+
+The user-visible contract under test:

+    kubectl apply  -> first completion writes run at epoch_old
+    kubectl delete
+    kubectl apply  -> second completion writes run at epoch_new
+    Both run dirs coexist and latest.txt points at epoch_new;
+    /api/v1/results/<ns>/<name> rejects the epoch-less lookup with 409 while
+    /api/v1/results/<ns>/<name>/runs/<epoch> serves either run independently.
+
+We drive the same disk-layout API the completion handler uses
+(``run_dir`` + ``write_latest`` + ``enforce_retention``) with two synthetic
+AIPerfJob bodies whose ``metadata.creationTimestamp`` values parse to
+distinct decimal epochs via ``epoch_key_from_body``. The HTTP assertions
+then exercise the real results-server routing through ``TestClient``.
+
+This stops short of spinning up a kind cluster: it proves the layout +
+routing contract end-to-end without the overhead of a real apiserver.

+# AIPerf Kubernetes E2E Test Suite
+
+Async pytest-based end-to-end test suite for AIPerf Kubernetes deployments. The trusted local gate uses Kind and the mock server; GPU, audit, slow, and cluster chaos scenarios are opt-in. Hermetic `chaos_common` injector-contract tests run in the trusted gate.
+
+## Quick Start
+
+### Local tests (Kind by default)
+
+Local tests use **Kind** by default for faster cluster lifecycle. Set `--k8s-runtime=minikube`
+to use Minikube instead. All settings can be configured via **CLI options** (`--k8s-*`) or
+**environment variables** (`K8S_TEST_*`). CLI takes precedence over environment.
+
+```bash
+# Trusted PR gate: build images, create an isolated Kind cluster, run serially,
+# and clean up. This excludes GPU, audit, slow, and cluster chaos scenarios;
+# chaos_common contract tests are included.
+make test-kubernetes-ci
+
+# CI already built both images, so avoid rebuilding them in pytest.
+make kubernetes-tests-ci args=--k8s-skip-build
+
+# Slow cluster fault injection (separate scheduled/manual CI matrix).
+make kubernetes-chaos-tests-ci
+make kubernetes-chaos-aiperf-tests-ci
+
+# Opt-in operator-vs-bare-pod artifact audit.
+make kubernetes-audit-tests-ci
+
+# Use Minikube instead of Kind
+make test-kubernetes-ci args=--k8s-runtime=minikube
+
+# Skip image builds (CLI or env var)
+uv run pytest tests/kubernetes/ -v --ignore=tests/kubernetes/gpu --k8s-skip-build
+K8S_TEST_SKIP_BUILD=1 uv run pytest tests/kubernetes/ -v --ignore=tests/kubernetes/gpu
+
+# Keep cluster after tests for debugging
+uv run pytest tests/kubernetes/ -v --ignore=tests/kubernetes/gpu --k8s-skip-cleanup
+
+# Reuse existing cluster (fastest for iteration)
+uv run pytest tests/kubernetes/ -v --ignore=tests/kubernetes/gpu --k8s-reuse-cluster
+
+# Combine options
+uv run pytest tests/kubernetes/ -v --ignore=tests/kubernetes/gpu --k8s-reuse-cluster --k8s-skip-build
+```
+
+The bare `pytest tests/kubernetes/` invocations above only drop the GPU suite. Neither
+`k8s_slow` nor `k8s_audit` is deselected by the default `addopts` marker expression, so
+those runs also pick up `chaos/`, `chaos_aiperf/`, and `audit/`. Add
+`-m 'not k8s_slow and not k8s_audit'` (or use `make kubernetes-tests-ci`, which passes the
+matching `--ignore` set) when you want the gate's scope.
+
+### GPU tests (Kind by default, with GPU passthrough)
+
+GPU tests default to **Kind** with GPU passthrough (requires `nvidia-smi`,
+`nvidia-ctk`, and Docker configured with `nvidia` as the default runtime).
+Set `--gpu-runtime=minikube` to use Minikube, or `--gpu-context` to use a
+pre-existing external cluster instead.
+
+GPU-specific settings use `--gpu-*` flags with `GPU_TEST_*` env var equivalents.
+Run `uv run pytest tests/kubernetes/gpu/ --help` for the full list.
+
+```bash
+# Create GPU cluster (Kind by default), deploy vLLM, run benchmarks
+./tests/kubernetes/gpu/run_vllm_tests.sh
+
+# Same via pytest directly (with CLI options)
+uv run pytest tests/kubernetes/gpu/ -v -m gpu --gpu-stream-logs
+
+# Reuse existing GPU cluster between runs
+uv run pytest tests/kubernetes/gpu/ -v -m gpu --gpu-reuse-cluster
+
+# Use an existing vLLM endpoint (skip vLLM deploy)
+uv run pytest tests/kubernetes/gpu/ -v -m gpu --gpu-vllm-endpoint http://vllm:8000/v1
+
+# Use a pre-existing external cluster instead of a local one
+uv run pytest tests/kubernetes/gpu/ -v -m gpu --gpu-context my-cluster
+
+# Use Minikube instead of Kind
+uv run pytest tests/kubernetes/gpu/ -v -m gpu --gpu-runtime=minikube
+
+# Change model and GPU memory utilization
+uv run pytest tests/kubernetes/gpu/ -v -m gpu --gpu-model facebook/opt-125m --gpu-mem-util 0.3
+
+# Run only Dynamo tests with single-GPU disaggregated mode
+uv run pytest tests/kubernetes/gpu/ -v -s -m dynamo --gpu-dynamo-mode disagg-1gpu --log-cli-level=DEBUG
+
+# Shell script also works with env vars
+GPU_TEST_REUSE_CLUSTER=1 GPU_TEST_STREAM_LOGS=1 ./tests/kubernetes/gpu/run_vllm_tests.sh
+```

+## Writing Tests
+
+### Async test with deployer
+
+```python
+@pytest.mark.asyncio
+async def test_benchmark_creates_namespace(
+    benchmark_deployer: BenchmarkDeployer,
+    small_benchmark_config: BenchmarkConfig,
+    kubectl: KubectlClient,
+) -> None:
+    """Verify benchmark creates its own namespace."""
+    result = await benchmark_deployer.deploy(
+        config=small_benchmark_config,
+        wait_for_completion=True,
+        timeout=300,
+    )
+
+    assert result.success
+    assert await kubectl.namespace_exists(result.namespace)
+```
+
+### Read-only test against module-scoped result
+
+```python
+def test_benchmark_completes(deployed_small_benchmark_module: BenchmarkResult) -> None:
+    """Verify benchmark completes successfully."""
+    assert deployed_small_benchmark_module.success
+    assert deployed_small_benchmark_module.metrics is not None
+```
+
+### Parameterized test
+
+```python
+@pytest.mark.parametrize(
+    "concurrency",
+    [
+        param(1, id="concurrency-1"),
+        param(4, id="concurrency-4"),
+        param(8, id="concurrency-8"),
+    ],
+)  # fmt: skip
+@pytest.mark.asyncio
+async def test_concurrency_levels(
+    benchmark_deployer: BenchmarkDeployer,
+    concurrency: int,
+) -> None:
+    """Test various concurrency levels."""
+    config = BenchmarkConfig(concurrency=concurrency, request_count=20)
+    result = await benchmark_deployer.deploy(config, wait_for_completion=True, timeout=300)
+    assert result.success
+```
+
+## Helpers API
+
+### BenchmarkConfig
+
+```python
+config = BenchmarkConfig(
+    endpoint_url="http://mock-server:8000/v1",
+    endpoint_type="chat",            # or "completions"
+    model_name="mock-model",
+    concurrency=5,
+    request_count=50,
+    warmup_request_count=5,
+    concurrency_ramp_duration=None,  # set to seconds to ramp concurrency over time
+    image="aiperf:local",
+    workers=2,
+    input_sequence_min=50,
+    input_sequence_max=100,
+    output_tokens_min=10,
+    output_tokens_max=50,
+)
+```
+
+### BenchmarkResult
+
+```python
+result = await deployer.deploy(config, wait_for_completion=True, timeout=300)
+
+result.success              # bool
+result.error_message        # str | None
+result.duration_seconds     # float
+result.namespace            # str
+result.jobset_name          # str
+result.status               # JobSetStatus | None
+result.pods                 # list[PodStatus]
+result.controller_pod       # PodStatus | None
+result.worker_pods          # list[PodStatus]
+result.metrics              # BenchmarkMetrics | None
+result.metrics.request_throughput       # float | None (req/s)
+result.metrics.output_token_throughput  # float | None (tokens/s)
+result.metrics.request_count            # int | None
+result.metrics.request_latency_avg      # float | None (ms)
+result.metrics.error_count              # int
+```
+
+### KubectlClient
+
+All methods are async:
+
+```python
+kubectl = KubectlClient(context="aiperf-pytest")
+
+await kubectl.apply(manifest)
+await kubectl.delete("deployment", "my-app", namespace="default")
+pods = await kubectl.get_pods("my-namespace")
+jobset = await kubectl.get_jobset("my-jobset", "my-namespace")
+logs = await kubectl.get_logs("pod-name", container="worker", namespace="ns")
+await kubectl.wait_for_rollout("deployment", "my-app", namespace="default")
+await kubectl.wait_for_jobset_completion("my-jobset", "my-namespace", timeout=300)
+```
+
+## Development Workflow
+
+### Fast iteration (reuse cluster)
+
+```bash
+# First run: creates cluster
+uv run pytest tests/kubernetes/test_deployment.py -v --k8s-reuse-cluster
+
+# Subsequent runs: reuses cluster + skip builds
+uv run pytest tests/kubernetes/test_deployment.py -v --k8s-reuse-cluster --k8s-skip-build
+
+# When done: cleanup manually
+kind delete cluster --name aiperf-pytest        # if using Kind (default)
+minikube delete -p aiperf-pytest                # if using Minikube
+```
+
+### Debugging failed tests
+
+```bash
+# Keep cluster after failure
+uv run pytest tests/kubernetes/test_benchmark.py -v -x --k8s-skip-cleanup
+
+# Inspect cluster
+kubectl get pods -A
+kubectl get jobsets -A
+kubectl logs -n <namespace> <pod> -c system-controller
+
+# GPU: reuse cluster for fast iteration
+GPU_TEST_REUSE_CLUSTER=1 ./tests/kubernetes/gpu/run_vllm_tests.sh
+
+# GPU: keep resources and enable full debug logging
+GPU_TEST_SKIP_CLEANUP=1 ./tests/kubernetes/gpu/run_vllm_tests.sh

+Submits an ``AIPerfSweep`` CR (no test-helper exists for sweep CRs, so the
+manifest is built inline), waits for the parent's ``status.phase`` to reach a
+terminal state, then shells ``aiperf kube results <sweep-name> --all`` to
+download every child via R2's CLI fan-out path. Reads the resulting
+``sweep_manifest.json`` (camelCase schema; see
+``aiperf.kubernetes.results._fetch_children_manifest``) to enumerate the
+``SweepCell`` list returned to the test.
+
+Exercising the user-facing CLI is the whole point of the audit — until R2,
+``aiperf kube results <sweep-name>`` errored on AIPerfSweep CRs, so the audit
+had to bypass it via ``kubectl get aiperfjob -l aiperf.nvidia.com/sweep=...``.
+R2 made the CLI sweep-aware, so we use it here.

+# AIPerf Chaos Suite — Feature Inventory
+
+A reference of what the suite under [`tests/kubernetes/chaos/`](.) actually contains, component by component. Companion to [`README.md`](README.md), which covers how to run scenarios and how they map to operator code. This document is for someone evaluating the suite's surface area — what helpers exist, what they do, and which pieces are generic vs. AIPerf-specific.
+
+Each section flags the AIPerf-coupling level:
+
+- **Generic** — works against any kubernetes operator/CRD with at most trivial renaming.
+- **Mixed** — generic mechanism with AIPerf-shaped defaults (label selectors, namespace constants); parameterizable.
+- **AIPerf-specific** — welded to AIPerfJob CRD lifecycle, JobSet labels, or operator-internal annotations.
+
+## 1. Test scaffolding & conventions
+
+**Pytest flags** ([`tests/kubernetes/conftest.py`](../conftest.py)). *Generic.*
+
+- `--k8s-reuse-cluster` / `K8S_TEST_REUSE_CLUSTER` — skip Kind cluster create/destroy; reuse a long-lived `aiperf-pytest` cluster for fast iteration.
+- `--k8s-skip-build` / `K8S_TEST_SKIP_BUILD` — skip image build; reuse existing images already loaded into the cluster.
+
+**Markers.** *Generic.*
+
+- `@pytest.mark.k8s_slow` — every chaos test carries this so the suite is opt-in (`-m k8s_slow`) and never runs on a default `pytest` invocation. Tests routinely wait 30 s for grace, 15 s for operator restart, or up to 2 minutes for benchmark completion.
+- `@pytest.mark.asyncio` — all tests are async.
+- `@pytest.mark.timeout(N)` — applied to long scenarios; current values range from 300 s to 1200 s (the sweep-controller kill).
+
+**Convention: cleanup in `finally`.** *Generic.* Every chaos test wraps fault injection in `try/finally`. `finally` clauses force-delete the CR/namespace and call `await injector.reset()` (toxiproxy) or `await injector.restore()` (mock server) so a leaked fault never poisons the next test. Belt-and-suspenders intentional.
+
+**Convention: `xfail` with flip-to-pass condition.** *Generic.* Scenarios that depend on unavailable infra ship as `@pytest.mark.xfail(strict=False, reason=...)` with a concrete condition in the reason string. `strict=True` is forbidden — chaos scenarios are exploratory by definition. No scenario currently carries an `xfail`; every test in the suite is expected to pass.
+
+## 2. ChaosInjector (kubectl-level faults)
+
+[`chaos_injector.py`](chaos_injector.py) — a single class wrapping `KubectlClient` with intent-revealing methods. Async throughout, no direct subprocess calls. Pytest fixture: function-scoped `chaos_injector` in [`conftest.py:38-41`](conftest.py).
+
+### 2a. Generic helpers (drop-in for any cluster)
+
+- `wait_for_pod_status_reason(namespace, label_selector, reason, timeout)` — poll `containerStatuses[*].state.waiting.reason` (and init-container statuses) for an exact match. Useful for `ImagePullBackOff`, `ErrImagePull`, `CrashLoopBackOff`, `CreateContainerError`. Returns the first pod name to surface the reason.
+- `wait_for_container_restart(pod, container, namespace, *, since_count, timeout)` — snapshot `restartCount` before fault injection, then block until it advances. The standard idiom for "kill the container, prove it actually restarted." Returns the new restart count.
+- `wait_for_cr_gone(namespace, name, timeout)` — block until a named CR disappears from the apiserver (not just "Terminating"). Returns wall-clock seconds elapsed. Currently hardcoded to `aiperfjob` kind but trivially generalizable.
+- `wait_for_pods_gone(namespace, timeout)` — block until every pod in a namespace is reaped.
+- `apply_resource_quota(namespace, name, hard_limits)` — apply an arbitrary `ResourceQuota` for K3-style quota-exhaustion tests.
+- `delete_resource_quota(namespace, name)` — idempotent NotFound-swallowing delete, safe for unconditional `finally`.
+
+### 2b. In-container fault injection
+
+- `kill_container_in_pod(namespace, pod, container)` — `kubectl exec <pod> -c <container> -- sh -c 'kill -KILL 1'`. Kills only the target container; kubelet decides restart per `restartPolicy`. Generic kubectl pattern, no AIPerf assumptions in the helper itself.
+- `kill_container_by_pid(pod, container_pid, namespace, exec_container)` — cross-container kill via shared PID namespace. Exec into a sidecar and issue `kill -9 <pid>` against a process in another container of the same pod. **Requires** the pod to have `spec.shareProcessNamespace: true`. *Generic mechanism, AIPerf-shaped only in that the caller must already know the target PID.*
+
+### 2c. AIPerf-specific helpers (illustrative, not portable as-is)
+
+The following are real and useful inside the AIPerf suite but assume AIPerfJob CRD shape, JobSet labels, or operator-internal annotations. Listed for completeness:
+
+- `delete_cr_no_wait(namespace, name)`, `delete_cr_twice(namespace, name)` — hardcoded `aiperfjob` kind.
+- `kill_operator_pod(force)` — hardcoded `aiperf-system` namespace and `app.kubernetes.io/name=aiperf-operator` selector.
+- `stamp_completion_claim(namespace, name, timestamp_iso)`, `read_claim_annotation(namespace, name)` — read/write `aiperf.nvidia.com/completion-claimed` annotation.
+- `wait_for_phase(namespace, name, phases, *, current_phase)` — `.status.phase` + `.status.currentPhase` composite waiter; the *idea* (composite waiter on phase + sub-phase) is generic, the field paths are not.
+- `get_controller_pod_name(namespace, job_name)`, `get_worker_pod_names(namespace, job_name)` — hardcoded JobSet `replicatedjob-name` label and `aiperf-<job>` naming.
+- `get_mock_server_pod_name(namespace, deployment)` — `app=aiperf-mock-server` selector.
+- `wait_for_operator_ready(timeout)` — block until every container of the operator pod reports Ready; hardcoded `aiperf-system` namespace and operator selector.
+- `create_invalid_cr(namespace, name, spec_patch)` — builds a minimal AIPerfJob manifest and applies it; the *idea* (apply a malformed CR via patch overlay) is generic, the embedded manifest is not.
+
+### 2d. Timing dataclass
+
+`ChaosTimings` — frozen dataclass with named timeouts (`cr_cleanup_seconds`, `pod_termination_grace`, `operator_recovery_seconds`, `completion_wait_seconds`) and one-line docstrings explaining each. Avoids magic numbers across tests. *Generic pattern, the values themselves are AIPerf-tuned.*
+
+## 3. ToxiproxyInjector (network faults)
+
+[`toxiproxy.py`](toxiproxy.py) — async REST client for a cluster-deployed [Toxiproxy](https://github.com/Shopify/toxiproxy) Deployment + Service. *Generic.*
+
+**Fixture manifest.** [`fixtures/toxiproxy.yaml`](fixtures/toxiproxy.yaml) deploys Toxiproxy into namespace `aiperf-chaos-toxiproxy` with the admin API on `:8474` and a small pool of named listen ports (`proxy-0`..`proxy-5` on 20000-20005, plus `mock-server` on 20010) for per-test proxies. Cluster-internal DNS: `toxiproxy.aiperf-chaos-toxiproxy.svc`.
+
+**Reserved listen ports** (stable across reruns so operator env-var overrides are deterministic):
+
+| Port | Purpose |
+|------|---------|
+| 20000 | Operator -> apiserver (C15) |
+| 20002 | Operator -> controller HTTP (C16) |
+| 20010 | Benchmark -> mock-server (B3 latency injection) |
+| 20001, 20003-20005 | Unreserved generic slots |
+
+**Fixture lifecycle.** Package-scoped `toxiproxy_injector` in [`conftest.py:44-61`](conftest.py).
+
+1. `ensure_deployed(kubectl)` — apply manifest, wait for rollout, open `kubectl port-forward` to admin API, probe `/version`.
+2. Per-test: `add_proxy` + `add_toxic`, run assertions, `reset()` in `finally`.
+3. `teardown(kubectl)` at package end — close port-forward, delete namespace.
+
+**Methods on `ToxiproxyInjector`:**
+
+- `add_proxy(name, listen, upstream)` — create a TCP proxy.
+- `add_toxic(proxy_name, toxic_type, attributes, *, name, stream, toxicity)` — attach a toxic (`latency`, `timeout`, `bandwidth`, `slow_close`, `reset_peer`, etc.) with optional `stream` (`upstream`/`downstream`) and partial `toxicity`.
+- `remove_toxic(proxy_name, toxic_name)`, `remove_proxy(name)` — targeted deletes.
+- `reset()` — wipe every proxy and toxic. Idempotent; safe in `finally`.
+- `teardown(kubectl)` — close port-forward and delete namespace.
+
+**Non-obvious invariants** (documented in the module docstring, worth knowing if you port this):
+
+- Every REST method opens its own short-lived `aiohttp.ClientSession`. Caching a session on the instance breaks under pytest-asyncio because the session binds to the loop it was created on, and chaos fixtures are package-scoped while individual tests run on function loops.
+- `reset()` uses `DELETE /proxies/<name>` per proxy, not Toxiproxy's `POST /reset`. The latter re-enables proxies rather than removing them.
+- The kubectl port-forward subprocess is kept alive across event loops, only the TCP port it binds is used by short-lived sessions.
+
+## 4. Composite fixtures (toxiproxy-routed operator)
+
+[`conftest.py:133-265`](conftest.py) — function-scoped fixtures that combine the toxiproxy injector with an operator redeploy so test code doesn't have to re-render the Deployment manifest. Both restore a plain (non-routed) operator on teardown even under `--k8s-skip-cleanup`, because the env overrides are shared mutable cluster state. *Mixed: mechanism is generic, env-var names are AIPerf-specific.*
+
+- `operator_ready_toxiproxy_routed` — operator redeployed with `AIPERF_K8S_CONTROLLER_HTTP_URL_OVERRIDE` pointed at `http://toxiproxy.aiperf-chaos-toxiproxy.svc.cluster.local:20002`, so operator -> controller HTTP traverses Toxiproxy.
+- `operator_ready_apiserver_toxiproxy_routed` — operator redeployed with `KUBERNETES_SERVICE_HOST` / `KUBERNETES_SERVICE_PORT` pinned at the Toxiproxy Service, `AIPERF_K8S_APISERVER_TLS_SERVER_NAME_OVERRIDE=kubernetes.default.svc` to preserve SNI through the TCP proxy. The apiserver proxy is created *before* operator deployment because kopf logs in immediately on startup.
+
+Both fixtures call a private `_assert_live_operator_env` precondition that diffs `kubectl set env deployment/aiperf-operator --list` against the expected env-var map and fails loudly when the override didn't land. Catches "redeployed but the env wasn't applied" without waiting for the assertion to time out 90 s later.
+
+## 5. MockServerInjector (upstream-service faults)
+
+[`mock_server_injector.py`](mock_server_injector.py) — chaos against the single-replica `aiperf-mock-server` Deployment that serves benchmark traffic in the k8s test harness. *Mixed: idiom is generic, default deployment name (`aiperf-mock-server`) and namespace (`default`) are AIPerf harness conventions.*
+
+**Methods on `MockServerInjector`:**
+
+- `restart(namespace, deployment)` — `kubectl rollout restart` for a rolling kill.
+- `delete_pod(namespace, deployment)` — `--grace-period=0 --force` for ungraceful crash (skips SIGTERM window).
+- `scale(namespace, replicas, deployment)` — change replica count; records prior count for restore.
+- `patch_env(namespace, env_var, value, deployment)` — `kubectl set env` to inject behavior (e.g. `MOCK_SERVER_ERROR_RATE=100` to force 100% HTTP 500 responses via `MockServerConfig.error_rate`).
+- `restore()` — reverse every mutation applied during the test in LIFO order. Called automatically by the fixture teardown.
+
+**Pattern worth porting.** Internally the class tracks an `_applied_ops: list[_AppliedOp]` and rolls back in `restore()` based on op kind (`env`, `scale`, `restart-annotation`). Each state-mutating fault method appends one entry; `delete_pod` appends none because the Deployment controller owns pod re-creation and there is nothing to unwind. Tests never track restore state themselves. Generic and worth lifting verbatim for any "perturb a Deployment in tests" use case.
+
+## 6. Helm chart integration
+
+[`deploy/helm/aiperf-operator/values.yaml:120-128`](../../../deploy/helm/aiperf-operator/values.yaml) ships `podTemplate.shareProcessNamespace: false` (production default), which [`templates/deployment.yaml`](../../../deploy/helm/aiperf-operator/templates/deployment.yaml) renders into the operator's `AIPERF_K8S_SHARE_PROCESS_NAMESPACE` env var. When true, JobSet pods are rendered with `Pod.spec.shareProcessNamespace: true`, enabling cross-container `kill` via `kubectl exec` (Section 2b).
+
+The opt-in-for-chaos, default-off-in-production tension is the load-bearing piece. *Generic pattern, AIPerf-specific env-var name.*
+
+## 7. Documented scenarios (taxonomy)
+
+The full scenario table lives in [`README.md`](README.md). The *taxonomy* — useful as a checklist when planning chaos coverage for any operator — is:
+
+- **Cancellation & idempotence** — delete mid-state, rapid double-delete, recreate-same-name after fault.
+- **Operator resilience** — operator pod kill mid-benchmark, recovery from durable mid-state markers left across operator restart.
+- **Workload pods** — controller-container kill, worker-pod kill, sidecar restart, in-flight fetch during restart.
+- **Helm lifecycle** — install -> run -> uninstall -> reinstall idempotence, mid-job upgrade, invalid values rollback, missing dependency CRDs.
+- **Churn** — rapid create/delete cycles, parallel-jobs partial-delete stability, invalid-spec surfacing.
+- **API disruption** — apiserver pause (TLS-preserving toxiproxy), intra-operator HTTP blackhole.
+- **Workload runtime** — upstream 5xx burst, upstream Deployment restart, latency injection.
+- **Infrastructure** — image-pull failures, DNS failures, namespace quota exhaustion.
+- **Sweep controller** — kill the sweep-controller pod mid-sweep and assert the restarted pod resumes rather than re-running completed variations.
+
+## 8. Bug shapes chaos runs have surfaced
+
+Past chaos sessions found (and led to fixes for) recurring bug *shapes*: stale imports on rarely-exercised recovery paths, undersized memory limits that work in steady state but OOM during cleanup, RBAC gaps that 403 silently on cross-namespace recovery, and durable mid-state markers that leak when the marker-holder dies. Useful as pattern recognition for "what kinds of bugs k8s chaos surfaces."
+
+## 9. Known gaps
+
+- **PID discovery lives in a test module, not the injector.** `kill_container_by_pid` requires the caller to pass `container_pid: int`, so every cross-container kill first needs a PID. The only implementation of that lookup is the module-level `_find_pid_by_cmdline` helper in [`test_chaos_jobset_pods.py`](test_chaos_jobset_pods.py), which walks `/proc/[0-9]*/cmdline` through the shared PID namespace. Nothing in [`chaos_injector.py`](chaos_injector.py) exposes it, so a new scenario in another module has to import the private helper or reimplement the walk. Promoting it to `ChaosInjector` would close the gap.
+- **`kill_container_by_pid`'s docstring points at a tool the runtime image lacks.** It suggests obtaining the PID via `kubectl exec <pod> -c <any> -- pgrep -n <name>`; the distroless-python runtime image has no `pgrep`, which is exactly why `_find_pid_by_cmdline` exists.

+# AIPerf Operator Chaos Suite
+
+Fault-injection tests for the kopf operator that back the AIPerfJob CRD. This suite sits alongside `tests/kubernetes/` and reuses its cluster/operator fixtures; it lives under `tests/kubernetes/chaos/` so the standard `K8S_TEST_*` flags (Kind cluster, image loading, mock server) all apply unchanged.
+
+Scenario waves: v1 (C1–C5b) covers operator lifecycle; the v2 expansion adds JobSet pods, Helm, churn, API disruption, and benchmark-runtime scenarios.
+
+## Running
+
+```bash
+# Full local suite (Kind; fresh cluster + image build)
+make kubernetes-chaos-tests-ci
+
+# Reuse an existing aiperf-pytest cluster (fastest iteration)
+uv run pytest tests/kubernetes/chaos/ -v -m k8s_slow --k8s-reuse-cluster --k8s-skip-build
+
+# Run a single scenario
+uv run pytest tests/kubernetes/chaos/test_chaos_cancellation.py::test_c1_delete_aiperfjob_mid_ramp -v
+```
+
+Every test is marked `k8s_slow` because scenarios intentionally wait on pod termination grace (~30 s), benchmark duration (~2 min for the longrun CR), or operator recovery (~15 s). Expect ~5 minutes per scenario on a modest laptop Kind cluster.
+
+The `run-kubernetes-chaos-tests.yml` workflow runs this legacy suite and the
+parallel unified-API suite in separate Kind jobs on pushes to `main`, nightly,
+and by manual dispatch. They remain outside the trusted PR gate because each
+suite is budgeted at up to 165 minutes of pytest time (210-minute job timeout).
+
+## What's here

+```
+
+The `ChaosInjector` helper is the single entry point for kubectl-level faults — methods like `delete_cr_no_wait`, `kill_operator_pod`, `stamp_completion_claim`, `wait_for_phase` hide the kubectl details so new scenarios read as intent not plumbing. `ToxiproxyInjector` and `MockServerInjector` play the same role for their respective fault domains.
+
+## Toxiproxy fixture
+
+`fixtures/toxiproxy.yaml` deploys a [toxiproxy](https://github.com/Shopify/toxiproxy) Deployment + Service in namespace `aiperf-chaos-toxiproxy`, exposing the `:8474` admin REST API and a small pool of listen ports for per-test proxy endpoints (20000-20005 plus the reserved 20010). The package-scoped `toxiproxy_injector` fixture in `conftest.py` port-forwards the admin API, wraps it in a typed `ToxiproxyInjector` client, and yields it to tests. API-disruption tests (`test_chaos_api_disruption.py`) and latency tests (`test_chaos_benchmark.py` B3) add proxies + toxics per-test and always call `await toxiproxy_injector.reset()` in `finally` so the next test starts from an empty proxy table. The Service is reachable cluster-internally as `toxiproxy.aiperf-chaos-toxiproxy.svc`, which lets tests route in-cluster traffic (operator → apiserver, benchmark → mock-server) through the proxy when the relevant endpoint-URL overrides are available.
+
+## Shared PID namespace
+
+An opt-in `podTemplate.shareProcessNamespace` Helm chart value (also exposed via the `AIPERF_K8S_SHARE_PROCESS_NAMESPACE` operator env) flips `Pod.spec.shareProcessNamespace` to true on JobSet pods. With it on, `kubectl exec <pod> -c <sidecar> -- kill ...` can reach the aiperf controller/worker PID in another container of the same pod; without it, each container has its own PID namespace and `kill` can only see PID 1 (the shim). The chaos suite sets it true for pods it drives via the `operator_ready_shared_pid` fixture in `test_chaos_jobset_pods.py`; the production default remains false so normal deployments don't accidentally expose cross-container process introspection. The runtime image is distroless-python with `bash` copied in and a busybox multicall on `PATH` — there's no `pkill` or `pidof`, so the module-level `_find_pid_by_cmdline` helper in `test_chaos_jobset_pods.py` walks `/proc/[0-9]*/cmdline` by hand to discover the target PID, then hands it to `ChaosInjector.kill_container_by_pid`.
+
+## Scenarios and how they map to operator code
+
+### Cancellation & operator resilience
+
+| Test | Design ID | Exercises |
+|------|-----------|-----------|
+| `test_c1_delete_aiperfjob_mid_ramp` | C1 | `lifecycle.on_delete` → `request_cancellation` + `close_progress_client` → owner-ref GC |
+| `test_c3_rapid_double_delete_is_idempotent` | C3 | `request_cancellation` / `close_progress_client` idempotence |
+| `test_c4_kill_operator_mid_benchmark_recovers` | C4 | kopf reconcile resume; durable `completion-claimed` annotation across operator restart |
+| `test_c5_orphaned_claim_recovers` | C5b | recovery from "operator died between claim and handle_completion" — `_recover_orphaned_completion_claim` in `monitor.py` |
+
+### JobSet / workload faults
+
+| Test | Design ID | Exercises |
+|------|-----------|-----------|
+| `test_c6_kill_controller_container_salvages` | C6 | controller-container termination salvage; preserves partial live metrics/checkpoints and marks results available |
+| `test_c7_kill_worker_pod_mid_benchmark` | C7 | JobSet pod restartPolicy plus controller reconfiguration when a replacement worker-group pod re-registers |
+| `test_c8_kill_event_bus_sidecar` | C8 | sidecar restart + event-bus reconnect inside controller pod (cross-container kill via shared PID ns) |
+| `test_c9_kill_results_sidecar_mid_fetch` | C9 | `fetch_results_with_retry` backoff while the results sidecar restarts; interaction with orphaned-claim recovery |
+
+### Helm / churn / API / benchmark
+
+| Test | Design ID | Exercises |
+|------|-----------|-----------|
+| `test_h1_install_job_uninstall_reinstall_is_clean` | H1 | Helm install → run CR → uninstall → reinstall; CRD + finalizer cleanup idempotence |
+| `test_h2_upgrade_with_inflight_job_preserves_cr` | H2 | `helm upgrade` mid-benchmark; CR + JobSet survive operator rollout |
+| `test_h3_invalid_values_fail_fast_and_recover` | H3 | Chart template error, rollback, clean reinstall |
+| `test_h4_missing_jobset_crd_surfaces_error` | H4 | operator behavior when `jobsets.jobset.x-k8s.io` CRD is absent; missing JobSet CRD must surface through `status.conditions` or `phase=Failed` |
+| `test_c10_rapid_create_delete_recreate_same_name` | C10 | `on_create` `clear_cancellation` unsticks a re-created CR with the old name |
+| `test_c11_parallel_jobs_delete_subset` | C11 | parallel reconcile; deletion of 5/10 CRs doesn't destabilize the others |
+| `test_c12_invalid_spec_surfaces_conditions` | C12 | malformed `spec.benchmark` surfaces as `phase=Failed` |
+| `test_c15_pause_apiserver_30s_recovers` | C15 | 30 s apiserver pause via toxiproxy; operator reconcile retries + CR Completes |
+| `test_c16_block_operator_controller_http_falls_back` | C16 | operator↔controller HTTP routed through toxiproxy; sidecar-result recovery completes after controller HTTP is blackholed |
+| `test_b1_mock_server_500s_mid_run` | B1 | benchmark tolerates 10 s burst of HTTP 500 from mock-server; error-rate metric populated |
+| `test_b2_mock_server_restart_mid_run` | B2 | benchmark recovers across a mock-server Deployment restart (connection refused → reconnect) |
+| `test_b3_mock_server_latency_injection` | B3 | per-request latency spike via toxiproxy toxic through the in-cluster mock-server proxy port |
+
+### Infrastructure faults
+
+| Test | Design ID | Exercises |
+|------|-----------|-----------|
+| `test_k1_image_pull_backoff_surfaces_pending` | K1 | non-existent container image; asserts `ImagePullBackOff` / `ErrImagePull` surfaces on JobSet pods and the CR reaches `Failed` within 120 s after the pod pull failure is visible |
+| `test_k2_dns_resolution_failure_fails_fast` | K2 | `endpoint.urls` pointing at an RFC 2606 `.invalid` hostname; asserts the CR reaches `Failed` within 120 s and status text names the DNS / endpoint failure domain |
+| `test_k3_resource_quota_exhaustion_fails_fast` | K3 | namespace `ResourceQuota` capped below the controller's memory request; asserts the CR reaches `Failed` within 120 s and status text or namespace events surface the quota admission rejection. Quota is unconditionally deleted in `finally` |
+
+### Sweep controller faults
+
+| Test | Design ID | Exercises |
+|------|-----------|-----------|
+| `test_sweep_controller_kill_resumes_correctly` | — | force-delete the sweep-controller pod mid-sweep; JobSet creates a replacement and the final aggregate covers all 8 child runs without re-running already-created children |
+
+`test_sweep_controller_kill.py` also carries `test_parse_find_file_count_handles_wc_output`, a pure unit test over the `find | wc -l` output parser used by that scenario. It needs no cluster but ships in this module (and therefore under `k8s_slow`) to keep the parser next to its only caller.
+
+### Active xfail scenarios
+
+There are currently no active `@pytest.mark.xfail` scenarios in the chaos suite. If a future scenario depends on unavailable infrastructure, keep the xfail reason tied to a concrete flip-to-pass condition and update this section.
+
+## Manual-run recipes for API-disruption scenarios
+
+These are the explicit operator-side runbooks for the two toxiproxy-backed scenarios.
+
+### C15 — pause apiserver traffic for 30 s
+
+The `operator_ready_apiserver_toxiproxy_routed` fixture deploys the operator with Kubernetes API env vars pointed at toxiproxy, and creates the apiserver proxy before the operator starts.
+
+Current manual recipe:
+
+1. Deploy `fixtures/toxiproxy.yaml` and confirm the Service `toxiproxy.aiperf-chaos-toxiproxy.svc` is reachable.
+2. Re-render the operator Deployment with:
+   - `KUBERNETES_SERVICE_HOST=toxiproxy.aiperf-chaos-toxiproxy.svc.cluster.local`
+   - `KUBERNETES_SERVICE_PORT=20000`
+   - `AIPERF_K8S_APISERVER_TLS_SERVER_NAME_OVERRIDE=kubernetes.default.svc`
+3. Configure toxiproxy proxy `apiserver` to forward `0.0.0.0:20000 -> kubernetes.default.svc:443`.
+4. Start the benchmark job.
+5. Add a `timeout` toxic for 30 s, then remove it.
+6. Assert the CR resumes normal reconciliation and reaches `Completed`.
+
+Important constraint: this needs an SNI-preserving L4 route to `kubernetes.default.svc:443`. Plain HTTP proxying is not enough because the apiserver connection is TLS.
+
+### C16 — block operator ↔ controller HTTP
+
+The controller JobSet DNS name is deterministic, so the proxy can target the controller Service hostname before the pod exists.
+
+Current manual recipe:
+
+1. Deploy `fixtures/toxiproxy.yaml`.
+2. Redeploy the operator with:
+   - `AIPERF_K8S_CONTROLLER_HTTP_URL_OVERRIDE=http://toxiproxy.aiperf-chaos-toxiproxy.svc.cluster.local:20002`
+     (bare scheme+host+port — `ProgressClient` appends `/api/progress`, `/api/workers`, and `/healthz` itself, so any path suffix here 404s every call)
+3. Create toxiproxy proxy `controller` on `0.0.0.0:20002` with upstream `<jobset>-controller-0-0.<jobset>.<namespace>.svc.cluster.local:9090` (the `API_SERVICE` port).
+4. Start the benchmark job and wait until it is in profiling.
+5. Add a `timeout` toxic on the proxy so operator HTTP calls to the controller fail.
+6. Assert the CR still reaches `Completed` via sidecar-result recovery.
+
+Use `tests/kubernetes/chaos/test_chaos_api_disruption.py::test_c16_block_operator_controller_http_falls_back` as the exact assertion template. Any future operator↔controller HTTP fault test should reuse the shared `operator_ready_toxiproxy_routed` fixture.
+
+## Bugs this suite has already surfaced
+
+All four bugs below were discovered by the v1 chaos suite and have been fixed:
+
+- **Fixed:** stale `get_api` import in `src/aiperf/kubernetes/completion_signal.py` — every benchmark completion's stop hook crashed silently.
+- **Fixed:** operator self-heals an orphaned `completion-claimed` annotation via `_recover_orphaned_completion_claim` (`src/aiperf/operator/handlers/monitor.py`); `test_c5_orphaned_claim_recovers` is no longer xfail.
+- **Fixed:** `tests/kubernetes/helpers/operator.py` now sets `AIPERF_K8S_SERVER_METRICS_MANAGER_MEMORY=256Mi` (was 128Mi, OOMed and blocked `SystemController`).
+- **Fixed:** `server_metrics_manager` auto-discovery uses the pod's own namespace (via `AIPERF_NAMESPACE` env / downward-API file) instead of endpoint-derived namespace — no more cross-namespace 403 spam.
+
+## Adding a new scenario
+
+1. Add a method to `ChaosInjector` (or `ToxiproxyInjector` / `MockServerInjector`) that expresses the fault at intent level — not raw kubectl args or REST calls.
+2. Put the test in the most-related file (`test_chaos_cancellation.py`, `test_chaos_jobset_pods.py`, `test_chaos_benchmark.py`, etc.) or add a new `test_chaos_<family>.py`.
+3. Tests MUST mark themselves `@pytest.mark.asyncio` and `@pytest.mark.k8s_slow` (via `pytestmark` at module top). Use `@pytest.mark.timeout(300)` on long scenarios.
+4. If the scenario needs cross-container `kill`, depend on `operator_ready_shared_pid` (not `operator_ready`). If it needs toxiproxy, depend on `toxiproxy_injector`. If it needs mock-server disruption, depend on `mock_server_injector`.
+5. Always wrap the injection + assertions in `try / finally` with a force-delete (and `toxiproxy_injector.reset()` / `mock_server_injector.restore()` as applicable) in `finally`. Chaos tests leak resources by definition; belt-and-suspenders cleanup keeps the cluster usable for the next test.
+6. If the scenario depends on infra not yet in place, ship it as `@pytest.mark.xfail(strict=False, reason=...)` with a concrete flip-to-pass condition in the reason string. Do NOT use `strict=True` — chaos scenarios are allowed to be exploratory.
+7. Document the new scenario in this README's scenario table.

+"""Chaos: API-disruption via toxiproxy.
+
+Covers chaos-expansion scenarios C15 and C16.
+
+Both scenarios require toxiproxy to front a live connection between
+the operator and either the apiserver (C15) or the SystemController
+HTTP API (C16).
+
+* **Apiserver (C15):** ``kubernetes_asyncio`` auto-configures from the
+  in-cluster env vars (``KUBERNETES_SERVICE_HOST`` /
+  ``KUBERNETES_SERVICE_PORT``) which the kubelet injects into every
+  pod. The C15 fixture re-deploys the operator with those env vars
+  pointed at the toxiproxy Service and sets
+  ``AIPERF_K8S_APISERVER_TLS_SERVER_NAME_OVERRIDE=kubernetes.default.svc``
+  so raw TCP passthrough still verifies the real apiserver certificate.
+  The apiserver proxy is created before the operator deploys so kopf login
+  and watch setup traverse toxiproxy from process start.
+
+* **SystemController HTTP (C16):** landed. The operator honors
+  ``AIPERF_K8S_CONTROLLER_HTTP_URL_OVERRIDE`` (chaos-only env var)
+  which swaps the per-CR JobSet pod DNS for a fixed URL in controller
+  API-port :class:`ProgressClient` calls. The shared function-scoped fixture
+  ``operator_ready_toxiproxy_routed`` (see
+  ``tests/kubernetes/chaos/conftest.py``) redeploys the operator with the
+  override pointed at toxiproxy and restores a plain operator
+  on teardown. New controller-HTTP fault-injection scenarios should
+  reuse that fixture rather than rolling their own.
+
+All tests force-delete their CR in ``finally`` and call
+``toxiproxy_injector.reset()`` to clear proxies/toxics across tests.

+cleanup. These tests deliberately do NOT use the module-scoped
+``helm_deployed`` fixture because they exercise install / upgrade /
+uninstall edge cases that must run against a freshly-deployed chart.
+
+Exercises these operator/Helm code paths:
+
+* ``deploy/helm/aiperf-operator`` chart templates and values resolution.
+* ``src/aiperf/operator/handlers/create.py`` preflight validation when
+  the JobSet CRD is missing (H4).
+* ``tests/kubernetes/helpers/helm.py::HelmDeployer.install_chart`` /
+  ``upgrade_chart`` / ``uninstall_chart``.
+* kopf reconcile continuity across an operator-pod recreation (H2).

+"""Chaos: real-world infrastructure faults.
+
+Covers chaos-expansion scenarios K1, K2, K3. These
+scenarios exercise operator behavior under faults that originate OUTSIDE
+the operator's code path — a broken container image, an unreachable
+endpoint hostname, and a namespace-level admission quota.
+
+Exercises these operator code paths:
+
+* ``src/aiperf/operator/handlers/create.py::on_create`` — CR accepted and
+  the JobSet created, but downstream pods never become Ready because
+  kubelet rejects the image pull (K1) or the quota admission webhook
+  rejects pod creation (K3). Tests that the operator now propagates those
+  infrastructure failures to CR phase ``Failed`` rather than retrying
+  silently.
+* ``src/aiperf/operator/handlers/monitor.py::_monitor_tick`` — when the
+  benchmark endpoint URL never resolves / never responds, the
+  SystemController surfaces a connection error rather than hanging
+  forever (K2).

+"""Toxiproxy client for chaos tests.
+
+Wraps the toxiproxy REST API (:8474) with an async, intent-revealing
+interface. Used by `test_chaos_api_disruption.py` to pause the apiserver
+and block operator-to-controller HTTP mid-run.
+
+Usage::
+
+    async def test_apiserver_pause(
+        toxiproxy_injector: ToxiproxyInjector,
+    ) -> None:
+        await toxiproxy_injector.add_proxy(
+            name="apiserver",
+            listen="0.0.0.0:20000",
+            upstream="kubernetes.default.svc:443",
+        )
+        await toxiproxy_injector.add_toxic(
+            "apiserver", "timeout", {"timeout": 0}
+        )
+        # ... observe operator behavior ...
+        await toxiproxy_injector.reset()
+
+Event-loop-scope invariant (DO NOT REFACTOR AWAY):
+    Every REST-API method opens its own short-lived ``aiohttp.ClientSession``
+    via ``async with`` and closes it before returning. This is intentional
+    and load-bearing: ``kubectl`` (and therefore this injector) is
+    package-scoped in the chaos conftest, but individual tests run on
+    pytest-asyncio's function loop. A cached ``aiohttp.ClientSession``
+    created in the package loop raises
+    ``RuntimeError: Timeout context manager should be used inside a task``
+    when reused from a function-scoped test. A per-call session (~10 ms
+    overhead) keeps the aiohttp timeout context bound to the current task.
+    The kubectl port-forward subprocess is safe to keep alive across
+    loops — only the TCP port it bound is used here, not its transport.

+# AIPerf Chaos — Unified-API Sibling Suite
+
+This directory holds **unified-API ports** of the 23 legacy AIPerf chaos
+scenarios that live in [`tests/kubernetes/chaos/`](../chaos/). Each ported
+scenario uses the `chaos_common` `faults.inject(...)` API instead of the
+legacy `ChaosInjector` / `MockServerInjector` / `ToxiproxyInjector` calls.
+
+**Legacy is NOT replaced.** The original `chaos/test_chaos_*.py` files stay
+unchanged and continue to ship. The ports here are a parallel surface that
+exercises the same scenarios through the unified ABC, validating that the
+adapter injectors faithfully wrap the legacy mechanisms.
+
+See:
+- `tests/kubernetes/chaos_common/` — unified `FaultInjector` ABC + injectors.
+- `tests/kubernetes/chaos_common/FEATURES.md` — capability matrix.
+
+## Relationship to `chaos/`
+
+| Surface | Where | Status |
+|---|---|---|
+| Legacy AIPerf scenarios | `tests/kubernetes/chaos/` | Continues to ship as-is |
+| Unified-API ports | `tests/kubernetes/chaos_aiperf/` (this dir) | Parallel coverage via `faults.inject(...)` |
+| Dynamo D-series | `tests/kubernetes/chaos_dynamo/` | Same unified API, Dynamo-targeting; not part of this checkout |
+| Adapter unit tests | `tests/kubernetes/chaos_common/` | Echo-only registry |
+
+The conftest in this package:
+
+1. Re-exports the legacy `chaos/conftest.py` fixtures by importing them
+   directly (importing a fixture function into a conftest registers it for the
+   package — modern pytest rejects `pytest_plugins` in any non-rootdir
+   conftest), so every ported test can still request `chaos_injector`,
+   `toxiproxy_injector`, `mock_server_injector`,
+   `operator_ready_toxiproxy_routed`, and
+   `operator_ready_apiserver_toxiproxy_routed` exactly as legacy tests do.
+   `operator_ready`, `kubectl`, and `operator_job_namespace` arrive via the
+   parent package-scoped `tests/kubernetes/conftest.py`.
+2. Overrides the echo-only `faults` fixture from
+   `tests/kubernetes/chaos_common/conftest.py` with an `InjectorRegistry`
+   pre-loaded with every concrete injector (`pod`, `workload`, `crd`,
+   `network`, `store`, `process`, `client`, `cluster`). The `CRDInjector`
+   is parameterized for `aiperfjob` / `aiperf.nvidia.com` /
+   `aiperf-system`; the `NetworkInjector` and `StoreInjector` are wired to
+   the legacy `toxiproxy_injector` (namespace `aiperf-chaos-toxiproxy`) so
+   the C15/C16/B3 reserved-port pool (20000, 20002, 20010) stays intact.
+3. Exports two helpers as plain `async def`:
+   - `wait_for_aiperfjob_phase(kubectl, namespace, name, phases, *, timeout, current_phase, poll_interval)`
+     — polls `.status.phase` (and optionally `.status.currentPhase`) with
+     the same JSONPath shape and TimeoutError style as
+     `ChaosInjector.wait_for_phase`.
+   - `scrape_aiperf_metrics(kubectl, namespace, *, deployment_name, metrics_port, timeout)`
+     — opens a short-lived `kubectl port-forward` to the operator pod,
+     hits `/metrics`, returns parsed Prometheus text as `{name: float}`.
+     Stub-grade; ported metrics-shape scenarios extend it as they land.
+
+## Running
+
+    make kubernetes-chaos-aiperf-tests-ci
+
+Or invoke pytest directly while reusing an existing cluster:
+
+    uv run pytest tests/kubernetes/chaos_aiperf/ -v -m k8s_slow \
+      --k8s-reuse-cluster --k8s-skip-build -n auto
+
+Same fixtures as `chaos/`; same cluster naming (`aiperf-pytest` under
+`--k8s-reuse-cluster`, otherwise `aiperf-<uuid-prefix>` or `aiperf-<xdist-worker>`).
+Run a single scenario:
+
+    uv run pytest tests/kubernetes/chaos_aiperf/test_chaos_cancellation_unified.py -v
+
+## Per-file marker pattern
+
+Every test file in this package must declare both markers at module level:
+
+```python
+import pytest
+
+pytestmark = [pytest.mark.asyncio, pytest.mark.k8s_slow]
+```
+
+`k8s_slow` opts the test into the slow-only run gate (these scenarios spin
+up a real AIPerf operator + JobSet); `asyncio` is required because every
+helper here is `async def` and the conftest fixtures are
+`pytest_asyncio.fixture`-based.

+"""Pytest plumbing for the chaos_aiperf scenario suite.
+
+Sibling of :py:mod:`tests.kubernetes.chaos_dynamo`. This module hosts the
+unified-API ports of legacy AIPerf chaos scenarios that live in
+:py:mod:`tests.kubernetes.chaos`. Composition is three layers:
+
+1. **Re-exported legacy chaos fixtures** -- direct fixture imports from
+   :py:mod:`tests.kubernetes.chaos.conftest` (importing a fixture function
+   into a conftest registers it for the package) so a ported test can request
+   ``chaos_injector``, ``toxiproxy_injector``, ``mock_server_injector``,
+   ``operator_ready_toxiproxy_routed`` and
+   ``operator_ready_apiserver_toxiproxy_routed`` exactly as legacy tests do.
+   ``operator_ready``, ``kubectl`` and ``operator_job_namespace`` arrive via
+   the parent package-scoped :py:mod:`tests.kubernetes.conftest`.
+
+2. **Unified faults registry** -- overrides the echo-only ``faults`` fixture
+   from :py:mod:`tests.kubernetes.chaos_common.conftest` with a per-test
+   :py:class:`InjectorRegistry` pre-loaded with every concrete injector the
+   ported AIPerf scenarios need. The :py:class:`CRDInjector` is parameterized
+   for ``aiperfjob`` / ``aiperf.nvidia.com`` and points at
+   ``k8s_settings.operator_namespace`` (``--k8s-operator-namespace``,
+   defaulting to :py:data:`DEFAULT_OPERATOR_NAMESPACE`). The
+   :py:class:`NetworkInjector` is wired to the legacy ``toxiproxy_injector``
+   (namespace ``aiperf-chaos-toxiproxy``, AIPerf-only port pool covering
+   the reserved C15/C16/B3 ports 20000/20002/20010) -- explicitly NOT the
+   ``dynamo_toxiproxy`` from chaos_dynamo, so a chaos_aiperf run never has
+   to deploy the chaos_common manifest.
+
+3. **Async helpers** -- :py:func:`wait_for_aiperfjob_phase` polls
+   ``.status.phase`` / ``.status.currentPhase`` with the same JSONPath
+   shape and TimeoutError message style as the legacy
+   :py:meth:`ChaosInjector.wait_for_phase`. :py:func:`scrape_aiperf_metrics`
+   is a stub over the operator's Prometheus ``/metrics`` surface that
+   ported metrics-shape scenarios can extend.

+"""Unified-chaos port of ``tests/kubernetes/chaos/test_chaos_api_disruption.py``.
+
+Covers chaos-expansion scenarios C15 and C16:
+
+* **C15** -- 30s apiserver timeout via Toxiproxy on the operator's
+  apiserver-routed Service; operator survives the pause and the CR
+  Completes once the toxic lifts.
+* **C16** -- operator -> SystemController HTTP blackhole via Toxiproxy
+  on the controller's HTTP API; the sidecar-results recovery path
+  drives the CR to Completed without further controller progress.
+
+This file mirrors the legacy module case-for-case; only the
+fault-injection surface differs:
+
+* Legacy: ``await toxiproxy_injector.add_toxic("apiserver", "timeout",
+  {"timeout": 0})``
+* Unified: ``async with faults.inject("network.timeout",
+  target={"proxy": "apiserver"}, attributes={"timeout": 0}): ...``
+
+The :py:data:`faults` registry (declared in this package's ``conftest.py``)
+wraps :py:class:`tests.kubernetes.chaos_common.injectors.network.NetworkInjector`
+around the legacy ``toxiproxy_injector``; the unified ``async with`` block
+adds the toxic on entry and removes it on exit, replacing the manual
+``add_toxic`` + ``remove_toxic`` pair the legacy file used.
+
+The heavyweight operator-redeploy fixtures
+(``operator_ready_apiserver_toxiproxy_routed``,
+``operator_ready_toxiproxy_routed``) are reused unchanged: this package's
+``conftest.py`` re-exports them by importing the legacy fixture functions.

+"""B1/B2/B3 unified-API ports - see chaos/test_chaos_benchmark.py for legacy.
+
+Exercises the benchmark-runtime fault paths against the mock inference
+server through the unified
+:py:class:`tests.kubernetes.chaos_common.registry.InjectorRegistry`
+``faults.inject(...)`` interface rather than the legacy
+:py:class:`MockServerInjector` / :py:class:`ToxiproxyInjector` direct
+calls. Each scenario maps to one unified fault id:
+
+* B1 -> ``workload.set_env`` against the mock-server Deployment to flip
+  ``MOCK_SERVER_ERROR_RATE=100``; benchmark must drive the AIPerfJob
+  to ``Completed`` and surface non-zero ``request_error_rate``.
+* B2 -> ``pod.kill`` against a discovered mock-server pod name; the
+  Deployment respawns the pod and the benchmark must tolerate the flap.
+* B3 -> ``network.latency`` toxic via the package-scoped Toxiproxy proxy;
+  ``request_latency.p99`` must reflect the injected 500 ms delay.
+
+The function-scope :py:data:`faults` registry inherited from
+:py:mod:`tests.kubernetes.chaos_aiperf.conftest` already pre-registers
+:py:class:`PodInjector`, :py:class:`WorkloadInjector`,
+:py:class:`NetworkInjector`, and :py:class:`CRDInjector`, so no extra
+``register()`` calls are needed in this module.
+
+Mock-server contract (see ``tests/aiperf_mock_server/config.py``):
+
+* ``MOCK_SERVER_ERROR_RATE`` (float, 0-100 percentage): inject random
+  HTTP 500 errors at the given rate. B1 sets it to ``100`` to force
+  every response to fail. This env var follows the ``MOCK_SERVER_``
+  prefix scheme from :py:class:`MockServerConfig` (``env_prefix``).
+* Deployment + Service name: ``aiperf-mock-server`` in ``default``,
+  port 8000 (see ``dev/deploy/mock-server.yaml``).

+"""Chaos: CR churn + invalid-spec validation, ported to the unified interface.
+
+Covers chaos-expansion scenarios C10, C11, C12. The legacy
+implementation lives at :py:mod:`tests.kubernetes.chaos.test_chaos_churn`;
+this module ports those three cases to the unified-chaos
+``faults.inject(...)`` API.
+
+Exercises these operator code paths:
+
+* ``src/aiperf/operator/handlers/create.py::on_create`` --
+  ``clear_cancellation(job_key(namespace, job_id))`` at the top of every
+  create, so a re-created same-name CR is not starved by the sticky
+  cancellation flag from a prior cycle (C10).
+* Per-CR isolation of reconcile timers and progress clients -- deleting CRs
+  A/B must not perturb CR C's monitor loop (C11).
+* ``src/aiperf/operator/handlers/create.py::_validate_spec`` -- raises
+  ``kopf.PermanentError`` and stamps ``phase=Failed`` with a
+  ``ConfigValid=False`` status condition when the spec converter rejects
+  the payload (C12).
+
+Port mappings vs. the legacy module:
+
+* ``chaos_injector.delete_cr_no_wait(ns, name)`` --
+  ``async with faults.inject("crd.delete", target={"ns": ns, "name": name})``.
+* ``chaos_injector.create_invalid_cr(ns, name, spec_patch)`` --
+  ``async with faults.inject("crd.apply_invalid", target=..., manifest=...)``.
+  The minimal AIPerfJob template the legacy method built internally now
+  lives in :py:func:`_build_aiperfjob_manifest` so the test owns the spec
+  shape it asserts against.
+* ``chaos_injector.wait_for_phase(...)`` -- :py:func:`wait_for_aiperfjob_phase`
+  from the package conftest (free async helper, no injector instance).
+* ``chaos_injector.wait_for_cr_gone(...)``,
+  ``chaos_injector.wait_for_pods_gone(...)``,
+  ``chaos_injector.read_claim_annotation(...)`` -- direct calls on the
+  ``chaos_injector`` fixture the package conftest re-exports by importing
+  the legacy fixture function; not yet covered by unified injectors.

+"""H1/H2/H3/H4 unified-API ports - see chaos/test_chaos_helm.py for legacy.
+
+These scenarios exercise the Helm chart lifecycle, not chaos-injection-via-
+``faults``. Every Helm operation (``install`` / ``upgrade`` / ``uninstall``)
+stays a direct :py:class:`HelmDeployer` call because no unified injector
+wraps Helm CLI -- and arguably shouldn't, since these tests *are* the chart
+contract. The unified port is therefore a near-copy of the legacy file:
+
+* The ``faults`` fixture from :py:mod:`tests.kubernetes.chaos_aiperf.conftest`
+  is requested by every test so the module is in the unified suite, even
+  when the test body never calls ``faults.inject(...)``. Future revisions
+  that weave in operator-pod kills (``operator.kill``) or in-flight CR
+  mutations (``crd.patch`` / ``crd.delete``) plug in without renaming.
+* The legacy ``ChaosInjector.wait_for_phase`` helper is replaced by the
+  free :py:func:`wait_for_aiperfjob_phase` async function from the conftest
+  -- no class needed, no extra dependency.
+
+H1: install -> run -> uninstall -> reinstall idempotence.
+H2: helm upgrade with a Running CR must not drop the CR.
+H3: invalid helm values fail fast, then recovery on the same namespace works.
+H4: missing JobSet CRD surfaces an operator-side error within 60 s.
+
+Exercises these operator/Helm code paths:
+
+* ``deploy/helm/aiperf-operator`` chart templates and values resolution.
+* ``src/aiperf/operator/handlers/create.py`` preflight validation when
+  the JobSet CRD is missing (H4).
+* ``tests/kubernetes/helpers/helm.py::HelmDeployer.install_chart`` /
+  ``upgrade_chart`` / ``uninstall_chart``.
+* kopf reconcile continuity across an operator-pod recreation (H2).

+"""Chaos (unified): real-world infrastructure faults (K1, K2, K3).
+
+Unified-API port of :py:mod:`tests.kubernetes.chaos.test_chaos_infra`. Covers
+chaos-expansion scenarios K1, K2, K3:
+
+* K1 -- non-existent container image surfaces ``ImagePullBackOff`` on
+  JobSet pods and the operator transitions the CR to ``Failed`` instead of
+  retrying silently.
+* K2 -- unresolvable endpoint hostname (``.invalid`` TLD per RFC 2606) is
+  surfaced to the CR as ``Failed`` with a DNS/resolution/endpoint cause
+  rather than hanging the worker forever.
+* K3 -- a tight namespace ``ResourceQuota`` blocks pod admission; the
+  operator surfaces the quota admission rejection on the CR within 120 s.
+
+Differences from the legacy module:
+
+* CR application flows through ``faults.inject("crd.apply_invalid", ...)``
+  rather than :py:meth:`OperatorDeployer.create_job`. The registry's LIFO
+  restore handles CR deletion on block exit, so the tests no longer need a
+  bespoke ``_force_delete`` finally.
+* K3's ``ResourceQuota`` lifecycle is owned by
+  ``faults.inject("cluster.resource_quota", ...)`` -- the restore handle
+  deletes the quota even when the body raises, matching the legacy
+  ``finally: chaos_injector.delete_resource_quota`` semantics with one
+  less call site.
+* ``wait_for_aiperfjob_phase`` replaces the inline poll loops from the
+  legacy file. The helper accepts a tuple of acceptable phases and
+  surfaces the last observed phase in the :py:class:`TimeoutError`
+  message; tests still catch the timeout to add scenario-specific context.
+
+The :py:meth:`ChaosInjector.wait_for_pod_status_reason` call in K1 is the
+one legacy primitive that does not yet have a unified equivalent -- it is
+a generic kubelet-status poller, not a fault injection, and the chaos_aiperf
+conftest exposes the legacy ``chaos_injector`` fixture so the helper is
+reachable without going through the registry.

+:py:meth:`ChaosInjector.kill_container_by_pid` or :py:meth:`ChaosInjector.
+kill_container_in_pod` directly are now routed through

+Non-fault ChaosInjector helpers (``get_controller_pod_name``,

+All four tests require the operator to be deployed with
+``AIPERF_K8S_SHARE_PROCESS_NAMESPACE=true`` so every JobSet pod sets
+``spec.shareProcessNamespace=true``; see the inline
+``operator_ready_shared_pid`` fixture below. The runtime image
+(``nvcr.io/nvidia/distroless/python``) copies ``bash`` from
+``env-builder`` and has a ``/busybox`` on ``PATH``; ``ps``, ``grep`` and
+``tr`` are busybox while ``kill`` is a bash builtin -- cmdline-based PID
+discovery via :py:func:`_find_pid_by_cmdline` is therefore the portable
+path on this image.

+# Chaos Common — Feature Inventory
+
+Reference for the unified chaos-injection module under
+[`tests/kubernetes/chaos_common/`](.). Companion to [`README.md`](README.md),
+which covers the Cilium-on-kind D704 gate and the chaos-suite invocation
+matrix. This document is the source-of-truth capability table for the unified
+chaos interface, with a `Status` column tracking what has shipped.
+
+The unified surface wraps two pre-existing systems:
+
+- **System A** — AIPerf chaos primitives under
+  [`tests/kubernetes/chaos/`](../chaos/) (`ChaosInjector`,
+  `ToxiproxyInjector`, `MockServerInjector`). Frozen — the 23 existing
+  AIPerf scenarios continue to use these classes directly.
+- **System B / C** — Dynamo-side chaos primitives (System B = existing,
+  System C = newer capabilities with mixed shipped, planned, and deferred
+  status). Dynamo-side adapters remain, but this checkout does not contain the
+  external `chaos_dynamo/` suite.
+
+Status legend:
+
+- shipped — concrete `FaultInjector` lives in `injectors/`, has unit
+  coverage in `chaos_common/test_*_injector.py`, and is registered by the
+  `chaos_aiperf` conftest.
+- planned — slot reserved in the spec; not yet implemented.
+- deferred — explicitly out of scope (no current scenario needs it; will
+  land when the first consumer arrives).
+
+## 1. Public API surface
+
+| Symbol | Location | Status | Notes |

+```mermaid

+    R -->|prefix match| W["WorkloadInjector\nHANDLES = ('workload',)"]

+```
+
+`InjectorRegistry.resolve` iterates registered injectors in registration
+order and returns the first whose `HANDLES` tuple matches the `fault_id`
+prefix. No matching injector surfaces as a `LookupError` listing every
+registered injector and its prefix tuple.
+
+## 4. Test fixture wiring
+
+The `chaos_common/conftest.py` ships an echo-only `faults` fixture (no
+real cluster mutations) — sufficient for adapter unit tests under
+`chaos_common/test_*_injector.py`. The `chaos_aiperf/conftest.py`
+overrides `faults` with a real registry that pre-registers every concrete
+injector against a live Kind cluster + AIPerf deployment + Toxiproxy.
+
+Pytest fixture resolution prefers the conftest closest to the test file,
+so AIPerf chaos tests pick up the real registry while adapter unit tests stay
+hermetic. The external Dynamo D-series registry is absent from this checkout.
+
+## 5. Frozen surface
+
+The following are intentionally NOT migrated to the unified API; they
+remain on the legacy classes in [`tests/kubernetes/chaos/`](../chaos/):
+
+- The 23 existing AIPerf chaos scenarios (`tests/kubernetes/chaos/test_chaos_*.py`).
+- `ChaosInjector` AIPerf-specific helpers (`stamp_completion_claim`,
+  `wait_for_phase`, JobSet/operator selector defaults). Listed in the
+  legacy [`tests/kubernetes/chaos/FEATURES.md`](../chaos/FEATURES.md)
+  § 2c.
+
+New scenarios should be authored against the unified API. The legacy
+classes stay because rewriting 23 passing tests carries no benefit
+proportional to the risk of regressing them.

+# AIPerf Chaos Common — Unified Fault-Injection Module
+
+This module hosts the shared fault-injection primitives (registries, ABCs,
+marks, and helpers) that the unified chaos suite uses to express
+reproducible fault scenarios across the AIPerf data plane, control plane,
+and Dynamo integration paths.
+
+## Status
+
+The shared injector registry and its hermetic adapter-contract tests are
+present and run in the trusted Kubernetes gate. AIPerf cluster fault scenarios
+live in `tests/kubernetes/chaos/` and `tests/kubernetes/chaos_aiperf/`.
+The external Dynamo D-series suite from the historical Kubernetes branch is
+not part of this AIPerf merge; the D-series commands below document that
+separate environment and are not runnable from this worktree.
+
+## Cilium-on-kind for D704
+
+### Why this matters
+
+D704 (`tests/kubernetes/chaos_dynamo/test_chaos_d7xx_infra.py::test_chaos_d704_hf_hub_egress_blackhole`,
+a Phase 4 forward-reference; neither the directory nor the file exists in
+this worktree) needs a NetworkPolicy-aware CNI to inject the fault it claims to: a
+blackhole on egress to the Hugging Face Hub. The default Kind CNI
+(`kindnet`) is NOT NetworkPolicy-aware — it silently ignores egress
+rules. Without Cilium (or Calico, or a real cluster whose CNI honors
+NetworkPolicy), the test cannot actually block the egress it asserts
+against, and any "passing" result would be a false positive.
+
+### The decision (option c)
+
+D704 ships with `@cilium_on_kind_required` from
+`tests/kubernetes/chaos_common/marks.py`, which is
+`pytest.mark.xfail(condition=not os.environ.get("KIND_HAS_CILIUM"), strict=True, reason=...)`.
+When `KIND_HAS_CILIUM` is unset (the default), the condition is true, so
+the test still runs but its failure is recorded as an expected failure —
+visibly present in the suite with a documented flip-to-pass condition.
+When the env var is set, the condition is false and the mark does not
+apply at all: a real failure on a Cilium-enforcing cluster becomes a loud
+pytest failure rather than a recorded xfail.
+
+### Recipe to make D704 actually pass
+
+Three approaches, in order of preference:
+
+#### Recipe A — Existing real cluster (recommended for CI)
+
+If the test target is a real cluster whose CNI already honors
+NetworkPolicy (DGX, GKE, EKS, AKS, any Cilium/Calico-equipped cluster),
+just set the env var when invoking pytest:
+
+```bash
+export KIND_HAS_CILIUM=1
+uv run pytest tests/kubernetes/chaos_dynamo/test_chaos_d7xx_infra.py -v
+```
+
+(The `chaos_dynamo/` path above is a Phase 4 forward-reference and does
+not exist yet; the command becomes runnable once Phase 4 lands.)
+
+One env var, no other changes. The name is `KIND_HAS_CILIUM` for
+historical clarity (kindnet is the broken case the gate exists for), but
+any CNI that enforces NetworkPolicy egress satisfies the gate.
+
+#### Recipe B — Cilium on Kind
+
+Bring up a dedicated kind cluster with the default CNI disabled, then
+install Cilium via Helm:
+
+```bash
+kind create cluster --name aiperf-pytest-cilium --config <(cat <<EOF
+kind: Cluster
+apiVersion: kind.x-k8s.io/v1alpha4
+networking:
+  disableDefaultCNI: true
+  kubeProxyMode: none
+EOF
+)
+
+helm repo add cilium https://helm.cilium.io/
+helm repo update
+
+helm install cilium cilium/cilium --version 1.16.4 \
+  --namespace kube-system \
+  --set kubeProxyReplacement=true \
+  --set k8sServiceHost=aiperf-pytest-cilium-control-plane \
+  --set k8sServicePort=6443
+
+kubectl --context kind-aiperf-pytest-cilium \
+  wait --for=condition=Ready pod -l k8s-app=cilium \
+  -n kube-system --timeout=180s
+
+export KIND_HAS_CILIUM=1
+export KUBECONFIG=$HOME/.kube/config
+```
+
+Verify Cilium is actually enforcing policy before running D704 (a quick
+sanity NetworkPolicy that blocks egress and a `kubectl exec ... curl`
+against an external IP is sufficient — Cilium should drop the
+connection). Bump the Cilium chart version to the current release at the
+time of running if 1.16.4 has aged out; the helm repo URL
+(`https://helm.cilium.io/`) is the long-term stable location.
+
+#### Recipe C — Document non-coverage
+
+If neither A nor B is feasible (e.g. a developer laptop without
+permission to install Cilium and no access to a real cluster), D704
+stays a recorded xfail and the D7xx suite runs one scenario short.
+Document this in the run report; do not silently delete the test.
+
+### Verifying the flip
+
+Quick sanity check that the gate behaves correctly:
+
+```bash
+KIND_HAS_CILIUM=1 uv run pytest \
+  tests/kubernetes/chaos_dynamo/test_chaos_d7xx_infra.py::test_chaos_d704_hf_hub_egress_blackhole -v
+```
+
+If Cilium is enforcing NetworkPolicy, the test passes. If the env var is
+set but Cilium is NOT actually enforcing (misconfigured install, wrong
+context, kindnet still on the path), the mark does not apply and the test
+fails LOUDLY as an ordinary failure. The reverse mistake is caught too:
+with the env var unset, `strict=True` turns an unexpected pass into a
+failure, so a cluster that quietly does enforce policy cannot masquerade
+as an expected failure. Either way the mismatch surfaces — better than a
+silent false positive.
+
+## Running the unified chaos suite
+
+The suite has three runnable layers; each layer requires progressively more
+infrastructure. Pick the lowest layer that exercises your change.
+
+### Adapter unit tests (no cluster needed)
+
+The injector adapters under `chaos_common/test_*_injector.py` use the
+echo-only `faults` fixture from this package's `conftest.py` — they assert
+the API contract (dispatch by prefix, LIFO restore, idempotent
+`AppliedFault.restore`) without touching a real cluster.
+
+```bash
+uv run pytest tests/kubernetes/chaos_common/ -n auto
+```
+
+These run on every PR via `run-kubernetes-tests.yml` (no opt-in marker).
+
+### External D-series scenarios (not included here)
+
+In the historical Kubernetes branch, the Dynamo-side D-series under
+`chaos_dynamo/test_chaos_d*.py` overrides
+the `faults` fixture with a real registry against a live cluster + dynamo
+deployment. Every test carries `@pytest.mark.k8s_slow` so a default
+`pytest` invocation skips the whole directory.
+
+```bash
+uv run pytest tests/kubernetes/chaos_dynamo/ -v -m k8s_slow \
+    --k8s-reuse-cluster --k8s-skip-build -n auto
+```
+
+`--k8s-reuse-cluster` and `--k8s-skip-build` are inherited from
+`tests/kubernetes/conftest.py` and let local iteration skip the
+~3-minute Kind bring-up plus image-build cycle.
+
+A single scenario, no marker filter:
+
+```bash
+uv run pytest tests/kubernetes/chaos_dynamo/test_chaos_d1xx_operator_admission.py \
+    -k test_chaos_d101_operator_kill -v
+```
+
+### D704 specifically (Cilium-enforcing CNI required)
+
+`test_chaos_d704_hf_hub_egress_blackhole` injects a NetworkPolicy egress
+deny against the Hugging Face Hub. Default Kind CNI (kindnet) silently
+ignores NetworkPolicy, so the test ships with `@cilium_on_kind_required`
+which expands to `xfail(strict=True)` unless `KIND_HAS_CILIUM=1` is set.
+
+```bash
+KIND_HAS_CILIUM=1 uv run pytest \
+    tests/kubernetes/chaos_dynamo/test_chaos_d7xx_infra.py \
+    -k test_chaos_d704_hf_hub_egress_blackhole -v
+```
+
+See the "Cilium-on-kind for D704" section above for the bring-up recipe.
+
+### Historical unified-suite shape
+
+The historical `k8s-chaos.yml` workflow exercised three directories;
+`chaos_common/` ran without `k8s_slow`, while the cluster suites required it:
+
+```bash
+uv run pytest tests/kubernetes/chaos_common/ -n auto
+uv run pytest tests/kubernetes/chaos/ tests/kubernetes/chaos_dynamo/ \
+    -m k8s_slow -n auto
+```
+
+See `tests/kubernetes/chaos_common/FEATURES.md` for the per-`fault_id`
+shipped/planned/deferred matrix.

+"""Unified :py:class:`FaultInjector` for the ``client.*`` fault domain.
+
+Pure client-side faults targeting an HTTP server, used to assert server-side
+cancellation paths and body-size-limit enforcement end-to-end. No kubectl,
+no Toxiproxy, no Kubernetes resources are mutated -- the only state in flight
+is an :py:class:`aiohttp.ClientSession` we own.
+
+Supported fault_ids:
+
+* ``client.cancel_request``  -> POST + read stream chunks, then force-close
+  the session mid-flight to drop the TCP socket. The k8s-side analog of
+  dynamo's ``tests/fault_tolerance/cancellation/utils.py`` ``CancellableRequest``
+  pattern, but built on aiohttp + ``session.close()`` instead of a socket
+  monkey-patch.
+* ``client.overflow_tokens`` -> POST a payload whose oversized field exceeds
+  the server's configured body limit (e.g. ``DYN_HTTP_BODY_LIMIT_MB``), then
+  capture the rejection response (expected HTTP 413).
+
+Both faults are one-shot mutations of an external service from the client
+side; :py:meth:`restore` is a no-op for both because the fault is the
+request itself, not a state change to be undone.

+Handles fault ids under the ``cluster.`` namespace (see spec §3.4):
+
+* ``cluster.resource_quota`` -- apply / delete a ``ResourceQuota`` on a
+  namespace. Restore deletes the quota; the inject site also records a
+  :py:class:`recovery.ClusterScopedMutation` so a crashed session can be
+  swept via ``pytest --chaos-sweep`` (Phase 1 plumbing).
+* ``cluster.network_policy.deny_egress`` -- apply a NetworkPolicy that
+  denies egress (optionally allowing intra-cluster traffic). Restore
+  deletes the policy. Only ENFORCES on NetworkPolicy-aware CNIs
+  (Cilium/Calico); on kindnet the policy applies but does nothing -- see
+  ``chaos_common/README.md`` Cilium-on-kind section. Tests that depend on
+  actual egress blocking must gate on ``cilium_on_kind_required``.
+* ``cluster.rbac.revoke`` -- ``kubectl patch`` a Role or ClusterRole to
+  drop a single (api_group, resource, verb) tuple. Restore re-adds the
+  verb. Uses JSON patch (``--type=json``) so the rule/verb indices are
+  unambiguous on both sides.

+* ``crd.delete`` -- ``kubectl delete <kind> <name> -n <ns> --wait=false``.
+* ``crd.delete_twice`` -- rapid double-delete (~0.5 s spacing) to exercise
+  finalizer idempotence on the apiserver.
+* ``crd.apply_invalid`` -- apply a caller-supplied malformed CR manifest;
+  restore deletes the CR with ``--ignore-not-found``.
+* ``crd.patch`` -- ``kubectl patch`` against the CR. Restore runs the
+  caller-supplied inverse patch in ``spec.params["restore_patch"]``; if
+  absent, restore logs a warning and no-ops.
+* ``crd.annotate`` -- stamp an annotation via ``kubectl annotate``. Restore
+  clears the annotation via the ``key-`` removal syntax.
+* ``operator.kill`` -- ``kubectl delete pod -l <selector> -n <ns> --force``.

+"""Pod-domain :py:class:`FaultInjector` for the unified chaos interface.
+
+Wraps the existing legacy pod-killing surface
+(:py:class:`tests.kubernetes.chaos.chaos_injector.ChaosInjector`) behind the
+new :py:class:`FaultInjector` ABC so callers can request pod faults through
+the same :py:class:`InjectorRegistry` dispatch path as every other domain.
+
+Three dotted ``fault_id`` values are recognized:
+
+* ``pod.kill`` -- force-delete the pod
+  (``kubectl delete pod --force --grace-period=0``). Issued directly through
+  the :py:class:`KubectlClient`; legacy ``MockServerInjector.delete_pod`` is
+  Deployment-coupled and therefore unsuitable here.
+* ``pod.kill_container`` -- kill PID 1 inside a single container of the pod
+  via ``kubectl exec ... -- sh -c 'kill -KILL 1'``. Delegates to
+  :py:meth:`ChaosInjector.kill_container_in_pod`.
+* ``pod.kill_pid`` -- kill a sibling container by PID via shared-PID-namespace
+  ``kubectl exec``. Requires ``spec.shareProcessNamespace: true`` on the target
+  pod (production default is False -- see ``AIPERF_K8S_SHARE_PROCESS_NAMESPACE``
+  and the chaos chart value). Delegates to
+  :py:meth:`ChaosInjector.kill_container_by_pid`.
+
+All three faults are **non-restorable**: killed pods are kubelet-recreated
+(or not, depending on JobSet policy), but the original PID/container state is
+gone. :py:meth:`_AppliedPodFault.restore` is therefore a logged no-op.

+"""Process-domain :py:class:`FaultInjector` for the unified chaos interface.
+
+Signals a specific PID inside a target container via ``kubectl exec``. This is
+the Kubernetes-side analog of dynamo's ``os.kill(rank_pid, signal.SIGSTOP)``
+pattern in ``tests/fault_tolerance/test_canary_rank_pause.py``: the engine PID
+lives inside a worker pod and we discover + signal it via kubectl exec.
+
+One dotted ``fault_id`` is recognized:
+
+* ``process.signal`` -- send the named signal to ``spec.target['pid']`` inside
+  ``spec.target['container']`` of ``spec.target['pod']``.
+
+Spec shape:
+
+* ``spec.target['kind']`` -- must be ``"pod"`` (only supported addressing kind
+  in this phase). ``"managed_process"`` is reserved for the deferred Phase per
+  the unified chaos design spec §7.
+* ``spec.target['ns']`` -- namespace.
+* ``spec.target['pod']`` -- pod name.
+* ``spec.target['container']`` -- container name inside the pod. Required; no
+  default because different SUTs use different container names.
+* ``spec.target['pid']`` -- integer PID to signal (visible inside the container
+  PID namespace).
+* ``spec.params['signal']`` -- signal name like ``"SIGSTOP"``, ``"SIGCONT"``,
+  ``"SIGTERM"``, ``"SIGKILL"``, ``"SIGUSR1"``. Validated against the shape
+  ``^SIG[A-Z][A-Z0-9]*$``; the exact Linux signal set is not hard-coded since
+  available signals vary by kernel / libc.
+
+Restore semantics depend on the signal sent:
+
+* ``SIGSTOP`` -- restore sends ``SIGCONT`` to the same PID. Leaving the process
+  stopped permanently would break the cluster, so restore IS meaningful here.
+* ``SIGTERM`` / ``SIGKILL`` -- process is gone; restore is a logged no-op
+  (kubelet owns container re-creation, same as :py:mod:`pod` faults).
+* Any other signal (``SIGUSR1``, ``SIGUSR2``, ``SIGHUP``, ...) -- no-op
+  restore. We do not attempt to "undo" an arbitrary userspace signal.

+"""Store-domain :py:class:`FaultInjector` for the unified chaos interface.
+
+Owns the ``store.*`` fault namespace, covering the two backing stores AIPerf
+test runs depend on when deployed alongside Dynamo: etcd (StatefulSet) and
+NATS (single-replica Deployment) from the ``dynamo-platform`` Helm chart.
+
+Recognized ``fault_id`` values:
+
+* ``store.etcd.kill`` -- ``kubectl delete pod -l <selector> --force
+  --grace-period=0`` against the etcd selector. The StatefulSet controller
+  re-creates the pod. Non-restorable (kubelet owns recovery).
+* ``store.etcd.timeout`` -- Toxiproxy ``timeout`` toxic on the etcd Service
+  proxy. Delegated to :py:class:`NetworkInjector`.
+* ``store.etcd.bandwidth`` -- Toxiproxy ``bandwidth`` toxic. Delegated.
+  **Known-flake risk:** etcd's gRPC channel multiplexes streams over HTTP/2,
+  and a bandwidth toxic operating at the byte layer can produce surprising
+  cascading failures (stream head-of-line blocking, client-side timeouts that
+  do not match the configured rate). D802 should prefer ``store.etcd.timeout``
+  if ``store.etcd.bandwidth`` proves flaky in CI.
+* ``store.etcd.partition`` -- full proxy disable (delegated).
+* ``store.nats.kill`` -- pod force-delete against the NATS selector.
+* ``store.nats.partition`` -- full proxy disable (delegated).
+* ``store.nats.slow_close`` -- Toxiproxy ``slow_close`` toxic (delegated).
+
+The Toxiproxy faults delegate to an internal :py:class:`NetworkInjector` so
+toxic-add / proxy-disable mechanics stay in one place; this injector only
+rewrites the ``fault_id`` from ``store.<svc>.<verb>`` to ``network.<verb>``
+and forwards the original ``target`` and ``params`` unchanged.
+
+The ctor selectors and namespaces default to dynamo-platform conventions
+(``dynamo-system`` namespace, ``app.kubernetes.io/name=etcd`` /
+``app=nats``) but accept overrides so AIPerf can reuse this injector if it
+ever bundles its own etcd/NATS.

+            image_pull_policy: Kubernetes imagePullPolicy for the operator pod.
+                Use ``"Never"`` for local Kind clusters (image pre-loaded via

+"""The headline KPI tiles must declare which SLA regime their number is from.
+
+The defect these cover: the sweep-detail KPI row headlined the unconstrained
+peak (3,842 tok/s at concurrency=9, TTFT p99 18,380 ms against a declared limit
+of 500) in a larger, gold, award-toned font directly beside a
+feasibility-filtered winner card reading 1,648 tok/s. Both numbers were correct;
+nothing on the page said they answered different questions.
+
+The fix labels rather than filters, so these tests pin two things that a
+source grep cannot distinguish: that a breach is announced when there IS a
+checkable constraint, and that NOTHING is announced when there is not -- an
+unconstrained sweep must not gain a feasibility claim it never earned.

+Regression for two defects seen together on the `gemma-bo4` adaptive sweep:

+   clicking "ITL avg" in the chart re-crowned the winner as the lowest-ITL
+   variation (``search_iter_0000``) instead of the objective's best.
+2. Even on the correct metric it ignored ``slaFilters``, so the winner was the

+"""The swept values must reach the UI on a LIVE sweep, through the real chain.
+
+A previous pass added ``variation_values`` to the children manifest so adaptive
+variations could render ``concurrency=17`` instead of ``search_iter_0008``. It
+was dead on a live sweep: SweepDetail skips ``GET /sweeps/{ns}/{name}/children``
+whenever ``detail.children`` is non-empty (sweep-detail.js), which is always
+true on a live sweep because the sweeps router builds ``detail.children`` from
+``list_all_jobs`` -- and ``AIPerfJobInfo`` had no such field, so
+``resolveSweepManifest`` fell to its last-priority source and lost the values.
+
+Every test here starts from a payload built by the PRODUCTION serializers
+(``AIPerfJobCR.to_info()`` / ``_archived_from_summary``) and runs it through the
+real ``resolveSweepManifest`` -> ``indexVariationValues`` chain in node. Tests
+that inject a manifest literal straight into the helper cannot catch this class
+of defect, which is exactly how it shipped.

+"""Shared Playwright + uvicorn harness for operator-UI end-to-end tests.
+
+Goals:
+  * One Chromium browser per test, so sync Playwright's private event loop
+    closes before the worker picks up unrelated pytest-asyncio tests.
+  * One in-process uvicorn server (a session-scoped daemon thread) serving the
+    operator results-server against a per-session tmpdir, with
+    kubernetes_asyncio bypassed.
+  * Per-test isolation through unique namespaces — tests seed their data at
+    ``<results_dir>/<unique_ns>/...`` and never collide.
+  * A registry that lets a test install a fake live AIPerfJob CR for a given
+    ``(ns, name)`` without monkeypatching the operator module from inside the
+    test body. Without an entry, ``find_aiperf_job`` returns ``None``
+    (= archived-only / no live cluster state).
+
+Each test receives a single ``harness`` fixture exposing the moving parts:
+
+    def test_X(harness):
+        harness.seed_run(ns=harness.ns, name="j", epoch="1714069323",
+                         summary=good_summary())
+        page = harness.goto_job_detail(harness.ns, "j", epoch="1714069323")
+        assert page.locator('[data-testid=...]').is_visible()
+
+Why a fixture object and not a flock of fixtures?
+
+  * Adversarial tests evolve fast and need to pull in seeds, the page, the
+    base URL, the registry — collecting these on one object keeps the test
+    signature short and the imports trivial for agents.
+
+Skips when Playwright or Chromium is unavailable (same pattern as
+``tests/ui/test_dashboard_js.py``).

+"""Adversarial Playwright tests that inject HTTP errors at the network layer.
+
+Each test uses ``page.route(...)`` to intercept a specific operator API
+endpoint and fulfill/abort it with a chosen failure mode, then asserts how
+the SPA degrades. Focused on:
+
+  * **Banner-on-failure** — the "Operator API unreachable" banner from
+    ``lib/api.js::poll`` must appear after ``POLL_FAIL_THRESHOLD=2``
+    consecutive failures.
+  * **No JS exceptions** — schema-shape surprises (empty dict, malformed
+    JSON, truncated body) must be tolerated without ``pageerror`` events.
+  * **Per-page error UX** — pages that own their own error state
+    (``jobs-error``, ``dashboard-jobs-error``, ``job-detail-error``,
+    ``sweeps-error``) must render the right card; the page-level error
+    state, not just the global banner, is the contract.
+  * **WS disconnect** — closing the per-job WS without an open job render
+    must not crash; the page renders REST data only.
+
+Out of scope (see sibling files):
+  * Routing-only edge cases — ``test_routing_adversarial.py``
+  * Happy-path harness regressions — ``test_harness_smoke.py``
+
+The harness ``Harness.page`` is a stock Playwright Page; every ``page.route``
+intercept is scoped per test via the per-test browser context, so leaks
+between tests are not possible (the context is closed in the fixture
+teardown).

+  * Live CR vs archived merge: pinned historical epoch must NOT pick up
+    live CR fields (``job_union.find_any_job``).
+  * URL-path encoding: hyphen / dot / percent / `+` / UTF-8 in namespace

+  * /epochs router behavior while the page is open (verifies the run-selector
+    listing and its latest pointer).
+  * Results-ready marker gating: artifacts list with vs without the
+    `.aiperf_results_ready.json` sentinel.
+  * Phase-stage decoding: legacy int request_count, missing request_count,
+    request_count.avg == 0 on Succeeded.
+  * Deep link to a non-existent job: page must not freeze on "Loading…".

+"""Adversarial Playwright tests for the operator-UI list / overview pages.
+
+Targets:
+  * Dashboard           ``/``
+  * Jobs list           ``/jobs``
+  * Sweeps list         ``/sweeps``
+  * Leaderboard         ``/leaderboard``
+  * History             ``/history``
+  * Compare             ``/compare`` and ``/compare/<ns>/<name>/<epochA>/<epochB>``
+
+These tests are *adversarial* — they seed pathological shapes (NaN/0 KPIs,
+oversized model names, missing summaries, source=live vs archived vs both,
+phase-XSS attempts, asymmetric epochs, empty sweeps) and assert the UI keeps
+rendering, no console errors fire, and no 5xx responses come back.
+
+Real bugs surfaced by a test cause the test to fail (no ``xfail``).

+"""Adversarial Playwright tests for the operator-UI client-side router.
+
+Focuses on:
+- Hash parsing edge cases (empty hash, double slashes, trailing slash,
+  query-only, repeated query keys, empty values, key-without-equals).
+- URL-encoded route params (encoded slash, space, plus, percent, unicode,
+  embedded newline) — does ``matchRoute`` decode them and does the page
+  survive the resulting param values?
+- Path-traversal-shaped inputs in ``:ns`` / ``:name`` segments.
+- Malformed ``/runs/:epoch`` values (non-numeric, zero, negative, float,
+  numeric overflow, whitespace-padded).
+- Excess path segments not matching any route -> Not Found, no JS crash.
+- ``/compare/:ns/:name/:epochA/:epochB`` with degenerate epoch pairs.
+- Browser history (``page.go_back``) round-trip across SPA navigations.
+- ``setQuery`` round-trip via direct ``window.location.hash`` mutation.
+- ``safeDecodeURIComponent`` truncated-UTF-8 fallback path.
+- Command palette (Ctrl+K) on dashboard with zero-result query.
+- Top-nav cross-links between Dashboard / Jobs / Sweeps.
+- ``hashchange`` listener pick-up on direct ``window.location.hash`` writes.
+- Concurrent route changes — final route is the last one requested.
+
+Out of scope: page-internal content (job-detail tables, sweep variations);
+covered in their own adversarial files.

+"""Adversarial Playwright tests for the operator-UI sweep-detail page.
+
+Goal: stress the contract between ``SweepDetail`` (``pages/sweep-detail.js``),
+``resolveSweepManifest`` (``pages/sweep-detail-helpers.js``), and the
+backing routers (``routers/sweeps.py``, ``sweep_union.py``) — specifically
+the joints where live CR state, archived aggregate.json on disk, the
+per-epoch ``children.json`` manifest, and the per-cell metrics from
+``getSweepCells`` are reconciled. Looking for:
+
+  * Epoch-resolution drift (latest.txt missing/stale, EPOCH_RE-rejected,
+    aggregate.json present without children.json or vice versa).
+  * Children manifest shape attacks (0/1/many, gaps, dupes, empty labels,
+    very-long labels, path-traversal-looking child names).
+  * Run-state miscounting (all-pending UI must not say "Completed";
+    runStates absent must not crash; cancelled separated from failed).
+  * Aggregate-vs-children divergence (totals mismatch in either direction;
+    child phase conflicts with aggregate roll-up).
+  * Sweep linkage on child page (sweep.json marker vs URL parent).
+  * Pathological run-summary rows (numeric strings, unknown metric keys,
+    missing ``name``).
+  * Direct deep-link to non-existent sweep does NOT stall on Loading.
+  * API surface for unknown valid-shape epochs returns 404 cleanly and
+    never bubbles 5xx into the page.
+
+Out of scope: events / logs / pods diagnostic panel (covered separately);
+artifact download / bundle streaming (covered in sweep-artifacts tests).
+
+Harness notes:
+
+  * ``conftest.py`` patches ``find_aiperfsweep`` / ``list_aiperfsweeps``
+    against its own live-CR registry, which defaults to "no live sweep".
+    We re-patch per test via :func:`_patch_sweep_cr_lookups` so each test
+    can declare its own live CR contents inline (or a flat ``None`` for
+    "archived only" scenarios).
+  * ``seed_sweep_aggregate`` writes ``profile_export_aiperf.json`` /
+    ``runs.json``, but ``sweep_union._record_from_archive`` reads
+    ``aggregate.json``. We write ``aggregate.json`` directly through
+    :func:`_seed_aggregate_json` so archived sweep records actually
+    surface through the API.

+"""Under Kubernetes the API outlives its benchmark until told to stop.
+
+The controller pod deliberately stays up after a run so `aiperf kube results`
+can read from it, and is retired explicitly via POST /api/shutdown -- what
+`aiperf kube shutdown` and the operator's graceful-exit handshake drive.
+Upstream's post-complete grace window is a competing mechanism: it is shorter
+than the operator's monitor interval, so the listener vanishes between two
+polls, the operator loses the endpoint, and the AIPerfJob never leaves its
+pre-terminal phase.
+
+These tests drive :meth:`BaseService._on_shutdown_command` **bound to a
+FastAPIService**, i.e. the function the dispatcher actually invokes. The
+previous revision called ``FastAPIService._on_shutdown_command`` unbound, which
+is why it stayed green for months while the behaviour was dead in production:
+that copy was shadowed by ``BaseService``'s hook and never ran. Verified on a
+live GPU cluster 2026-08-29 -- the API container exited 0 five seconds after its
+benchmark, with no deference log line, and ``aiperf kube results --from-pods``
+then failed with "API service may not be listening on port 9090".

+Focuses on:
+- explicit target resolution versus the persisted last benchmark fallback.
+- namespace, kubeconfig, and kube-context propagation before mutating Kubernetes.
+- text/JSON cleanliness knobs that suppress fallback chatter for machine output.
+- idempotent 404 delete behavior versus non-404 conflict propagation.
+- confirmation-prompt abort semantics.
+- AIPerfJob versus AIPerfSweep target distinction before a destructive action.

+"""Adversarial tests for kube debug trust boundaries.
+
+Focuses on:
+- missing-target paths that must return without touching pod diagnostics;
+- kubeconfig, kube-context, namespace, and sweep child selector propagation;
+- best-effort aggregation when one diagnostic source is malformed;
+- per-container stderr/log-fetch placeholders rather than all-or-nothing failure;
+- no direct ``print`` or ``rich.print`` bypass around the kube console facade.
+
+Out of scope: JSON/result dataclass schema and subprocess stderr handling because
+``aiperf kube debug`` currently exposes text-only diagnostics and performs no
+subprocess shellouts. See ``test_preflight_adversarial.py`` for those contracts.

+"""Adversarial tests for kube generate/validate kind dispatch.
+
+Focuses on:
+- AIPerfJob versus AIPerfSweep dispatch from config shape and CR ``kind``.
+- Trust-boundary YAML cases: multi-document streams, missing kind, unknown kind.
+- JSON/text output surfaces preserving path, kind, and ``spec.sweep`` context.
+- Namespace propagation for generated CRs without leaking kube client-only options.
+
+Out of scope: cluster submission, kubectl invocation, and raw JobSet manifests; see
+``tests/unit/cli_commands/kube/test_profile_deploy.py`` and
+``tests/unit/cli_commands/kube/test_profile_deploy_direct.py`` for those paths.

+- search/list short-circuits don't invoke `_generate_template`
+- `_generate_template` maps CLI args onto the template helpers correctly

+"""Adversarial tests for the kube operator-install surface that exists today.
+
+The branch does not expose ``aiperf kube install``, ``upgrade``, or
+``uninstall`` modules. Operator lifecycle management is documented as direct
+Helm usage, while the CLI install-adjacent paths are:
+- ``aiperf kube generate --operator`` renders AIPerfJob/AIPerfSweep CRs for an
+  already-installed operator.
+- ``aiperf kube profile`` probes for the AIPerfJob CRD and falls back to direct
+  manifests when the operator is absent.
+- ``deploy/helm/aiperf-operator`` is the chart users install/upgrade/uninstall

+  or list_aiperf_jobs/list_jobsets (without), and prints a table
+- mutually-exclusive status filters are rejected
+- empty results print the "No AIPerf jobs found" message
+- `_resolve_status_filter` enforces "at most one filter" semantics
+- API failures surface through `cli_utils.exit_on_error` instead of bubbling

+- CLI option propagation into the Kubernetes client context.
+- JSON output remaining machine-parseable when human logs would otherwise render.
+- Namespace, RBAC, timeout, and dispatcher error classification.
+- Partial aggregation when one non-connectivity check fails.
+- Subprocess trust boundaries for missing tools and stderr preservation.

+"""Tests for `aiperf.cli_commands.kube.profile_deploy_direct`.
+
+Companion to ``test_profile_deploy.py`` (which already covers ``_apply_manifest``
+and ``wait_or_detach``). This file exercises the helpers that wrap the direct-
+deploy (no operator) flow:
+
+- ``_prepare_direct_deploy`` — applies K8s overlays, computes pod count
+- ``_apply_all_manifests`` — opens the API, dispatches per manifest, and
+  rejects every resource name collision, Namespace included
+- ``deploy_direct`` — full glue: dry-run prints YAML, wet-run creates resources
+  and saves the last-benchmark hint, then hands off to ``wait_or_detach``

+"""Exit-code contract for the target-addressing `aiperf kube` subcommands.
+
+The convention these tests pin down is "validation/retrieval commands gate,
+addressing commands narrate", with one carve-out: a target that does not exist
+at all fails the shell, so `attach` and `logs` can be used as CI existence
+checks. Covered here:
+
+- job absent -> exit 1 on every `logs` path and on `attach`
+- job present but pods already collected/GC'd -> exit 0, no false success line
+- ``--ignore-not-found`` -> exit 0 for an absent job, mirroring kubectl
+- the bulk `--output` dump reports what actually reached disk
+
+Out of scope: live Kubernetes API behaviour, and the `results` command, which
+deliberately keeps its pre-existing exit-1-on-any-failure retrieval semantics
+(see ``test_logs_attach_results_adversarial.py``).

+- YAML structure validation: apiVersion, kind, metadata.name, nested spec.benchmark
+- Kubernetes name validation: length, pattern
+- Unknown spec field detection: warning vs strict error
+- AIPerfConfig validation via AIPerfJobSpecConverter
+- DeploymentConfig, worker count validation
+- File-level error handling: missing, unreadable, invalid YAML
+- Multi-file validation with pass/fail counts
+- CLI entrypoint integration

 Bug 5: pyzmq's async sockets call loop.add_reader() / add_writer(), which the
 default Windows ProactorEventLoop does not implement. AIPerf forces the
-SelectorEventLoopPolicy on Windows before the loop is created. These tests
-mock IS_WINDOWS to exercise both branches from non-Windows CI.
+SelectorEventLoopPolicy on Windows before the loop is created. That policy
+switch now lives in ``aiperf.common.event_loop`` (see
+``tests/unit/common/test_event_loop.py``) because it must be applied from
+every real process entrypoint, not just ``bootstrap_and_run_service`` --
+this file keeps only the Windows-timer-resolution tests, which are specific
+to the service-bootstrap path.

+"""CLI flags combined with ``--config`` must never be silently ignored.

+``resolve_config`` historically routed only a small subset of ``CLIConfig``
+fields into the YAML-supplied base config; every other explicitly-set flag was
+silently discarded. A user passing ``-f base.yaml --random-seed 42`` got a run
+with a different seed than they asked for, with no diagnostic.
+
+These tests pin the guarantee that replaces that behavior: a flag that cannot

+overwrites a value the user never mentioned -- how ``images.batch_size=1``
+and ``turns.stddev=0`` would have leaked before this was guarded.

+**No dead routing.** Every field the registry claims is routed under
+``--config`` must actually change the resolved config. ``ROUTED_UNDER_CONFIG``
+computes the input section as a complement, so a newly-added field is
+classified as routed automatically; this test is what stops that convenience

+``build_mlflow``, ``build_otel``, and ``build_network_latency`` have always

+never called them -- so every ``--mlflow-*`` flag, ``--otel-url``, and the

+    runs on a frozen clock, its timers never fire, and some unrelated test far
+    down the run hangs in ``epoll.poll()`` with nothing naming the culprit.
+
+    That is not hypothetical. ``TimeTraveler.start_traveling`` patches the

+    real function, re-installing a dead TimeTraveler bound method for the rest
+    of the process.
+
+    Patch a module-local binding instead: have the source do
+    ``from time import monotonic`` and patch ``some_module.monotonic``.
+
+    This is a teardown hookwrapper rather than an autouse fixture on purpose --
+    it must observe the slot after *all* fixture finalization, including
+    ``monkeypatch``, and no fixture can reliably order itself outside a builtin
+    that other autouse fixtures depend on.

+reaped the moment it reports in.

+"""A worker that stops answering must stop receiving credits.
+
+Documented 2026-03-09 and still open: the sticky router only dropped a worker
+on an explicit WorkerShutdown, so a pod that died without one kept being
+selected. Every credit routed to it was never returned, which starves the
+concurrency limiter -- throughput degrades silently with nothing in the logs
+naming the cause.
+
+A dead worker cannot report its own death, so detection has to be router-side.
+It must NOT be based on credit-channel silence: a worker emits nothing between
+its FirstToken and its CreditReturn, so a reasoning model with a minute of
+decode is indistinguishable from a crashed pod, and evicting on that killed
+healthy workers one at a time until routing had none left. Detection keys off
+service heartbeats, which the worker publishes on its own timer regardless of
+what request it is running. Eviction is terminal when active worker-local work
+would be lost.

+"""Chart-rendering invariant tests for the aiperf-operator Helm chart.
+
+These tests shell out to ``helm template`` and assert chart-output invariants
+that round-3 / round-4 audits identified as load-bearing — the kind of bug
+that sails through code review because the chart YAML "looks right" but the
+rendered Service/ServiceMonitor/Deployment combo silently breaks a feature.
+
+Specifically locks in:
+- The single FastAPI surface (``AIPERF_OPERATOR_BASE_URL``) is auto-templated
+  from ``Release.Name`` + ``Release.Namespace`` + ``Values.resultsServer.port``.
+  Caught by the round-2 collapse audit only after a live dgx run 404'd on
+  ``status.apiUrl``.
+- The Service exposes the metrics port when ``operator.metrics.port>0``,
+  AND the ServiceMonitor scrapes ``port: metrics`` (not ``port: health``).
+  Caught by round-3 chart audit — Prometheus scraping was silently broken
+  in production because the Service didn't expose 9090.
+
+Each test is a pure ``helm template`` invocation; no kind cluster, no apply.
+Runs as a unit test so a regression fails fast in pre-commit / CI.

+Complements ``tests.unit.kubernetes.test_port_forward`` (which re-exports
+``stream_progress_from_api`` via ``port_forward``) by exercising the
+contract of ``progress_stream`` directly:
+
+- Subscription handshake happens before ``on_message`` is invoked.
+- ``TimeoutError`` is treated like ``aiohttp.ClientError`` for retry.
+- ``ConnectionError`` after ``max_retries`` preserves the original exception
+  as ``__cause__``.
+- Exceptions raised inside ``on_message`` propagate after the session /
+  websocket context managers run their ``__aexit__`` cleanup.
+- Backoff is clamped to ``_WS_MAX_BACKOFF`` during long retry chains.

+AIPerfJob YAML, checks apiVersion/kind/metadata/spec shape, the Kubernetes
+name regex, unknown-field detection (warning vs. error under --strict), and
+runs the spec through the operator's spec converter to catch schema errors
+before ``kubectl apply``.

+"""Edge-case tests for aiperf.kubernetes.watchdog.BenchmarkWatchdog.
+
+Complements ``test_watchdog.py`` by exercising paths that file leaves cold:
+
+- Monitor-loop exception swallow + cancellation path through stop()
+- Tick-scheduled checks (node@tick=2, stale-ns@tick=3, resources@tick%6==0)
+- _check_stale_namespaces: 403 ApiException -> INFO, non-403 -> debug, generic exception
+- _check_pod_resources: peak tracking, memory-growth dedup, exception swallow
+- _check_node_resources: exception swallow on listing failure
+- _check_events: exception swallow (already partially covered, but the silent path)
+- report(): node_cpu_pct / node_mem_pct / stale_ns_count fields propagate
+- _check_elapsed_time: no-op when timeout is None
+- _add_problem: INFO severity branch (only WARNING/CRITICAL covered elsewhere)
+- ContainerInfo healthy running state: produces no problems

+    """Undo ``importlib.reload`` side effects that strand module singletons.
+
+    Several operator tests call ``importlib.reload(aiperf.operator.environment)``
+    (directly or via a fixture) to re-materialize ``OperatorEnvironment`` from a
+    fresh set of ``AIPERF_*`` env vars. ``reload`` rebinds the module's
+    ``OperatorEnvironment`` (and the nested ``RESULTS``/``SERVICE``/``DASHBOARD``
+    settings) to brand-new instances *in place*. Production code reads the
+    singleton via a function-local ``from aiperf.operator.environment import
+    OperatorEnvironment`` at call time, so it picks up whatever the module
+    currently holds — but sibling test files captured the *original* object at
+    their own import time. After a reload, ``monkeypatch.setattr`` on the stale
+    object no longer affects the value the handler reads (it falls back to the
+    ``/data`` default), so a later test in the same process sees its patch
+    silently ignored.
+
+    This snapshots the live module objects before each test and rebinds them
+    afterwards if a reload swapped them out, keeping every test file's
+    module-level reference and the production read path pointed at one object.
+
+    Restoring the ``environment`` module attribute alone is not enough. Most
+    operator modules bind the singleton at *their* import time (``from
+    aiperf.operator.environment import OperatorEnvironment``), so any module
+    first imported — or itself reloaded — inside a test's reload window captures
+    the post-reload instance. Rebinding only ``environment`` then orphans that
+    instance: the module attribute points at the original, a consumer such as
+    ``routers.mutating_auth`` points at the orphan, and a later
+    ``monkeypatch.setattr`` on the object reachable from the module is invisible
+    to the handler that reads the orphan. So sweep every ``aiperf`` module and
+    repoint each captured reference at the original singleton.

+Locks delete-path contracts that are easy to regress during cleanup refactors:

+1. AIPerfJob deletion requests cooperative cancellation before closing the

+2. AIPerfJob deletion stays finalizer-free with respect to owned resources:
+   JobSet, ConfigMap, Role, and RoleBinding cleanup is left to Kubernetes
+   ownerReference GC, not direct delete calls from the handler.
+3. AIPerfSweep deletion best-effort patches child AIPerfJobs with

+   not block parent deletion.
+4. Re-fired delete handlers are idempotent and keep the cancellation flag set.

+"""Progress-client lifetime tests for the results-fetch retry loop.
+
+The client cache is bounded, so a long fetch loop can have its cached
+``ProgressClient`` evicted by another job's monitor tick. An evicted client
+drops its aiohttp session and raises ``RuntimeError`` on every later call, so
+the fetch loop must re-resolve its client per attempt rather than holding one
+reference for the lifetime of the run.
+
+Out of scope: the cache's own eviction ordering, covered by

+Handler modules acquire progress clients through the leased

+A handler that keeps an unused ``get_or_create_progress_client`` import is

+- preserving per-run values without aggregating unrelated benchmark runs
+- model/endpoint metadata carried through compare responses
+- stale runs_index rows falling back to disk-authoritative summaries

+Focuses on:
+- .zst stored-name to display-name mapping in file-list responses
+- content negotiation for zstd-stored JSON/JSONL/Parquet artifacts
+- stored-size metadata rather than decompressed-size metadata
+- malformed compressed profile exports failing closed instead of returning corrupt JSON
+- raw plus compressed sibling preference for quick export and per-file download routes
+- results-ready gating for final compressed artifacts and checkpoint bypass semantics
+
+Out of scope: run discovery and path traversal, covered by sibling results-files tests.

+- invalid metric identifiers with and without an open runs_index cache
+- duplicate AIPerfJob names across namespaces staying namespace-qualified
+- stale runs_index rows falling back to disk-authoritative summaries
+- missing summary files returning stable empty/404 contracts

+"""Adversarial tests for the operator results-files router.
+
+Focuses on:
+- path traversal and symlink escape attempts at the filename trust boundary
+- results-ready marker gating for final top-level artifacts
+- checkpoint bypass semantics while a run is still processing
+- stale or missing runs-index fallback to the PVC artifact tree
+- malformed artifact trees and URL-encoded namespace/job identifiers
+
+Out of scope: analytics SQL behavior, covered by sibling operator results tests.

+"""Regression locks for reviewer-accepted operator router fixes.
+
+Each test here pins one defect that was fixed once and could silently
+regress under a merge or rebase, because the fix is a one-line predicate or
+a helper swap with no other caller asserting on it:
+
+- ``jobs.event_sort_key`` parses timestamps instead of comparing ISO strings
+- sweeps counter/index coercion degrades on a malformed aggregate/manifest
+- ``results_analytics`` falls back to the ``job_spec.json.zst`` companion
+- ``dashboard_proxy`` drops stale upstream framing headers but keeps
+  ``content-encoding``, which still describes the bytes it relays
+- ``results_files_io`` allows nested files inside allowlisted subtrees
+- the bundle generator does not await during teardown on client disconnect
+- ``/jobs/{ns}/{name}/events`` and ``/logs`` validate their path params
+
+Out of scope: the broader endpoint contracts, covered by the adversarial
+suites in this directory.

+Focuses on:
+- AIPerfSweep child rollup bucket isolation for cancelled vs failed children.
+- ``currentChildRef`` selection across running, pending, terminal, and malformed children.
+- ``status.runs[]`` truncation safety nets that keep huge sweeps under the apiserver limit.
+- Child metadata passthrough trust boundaries: user keys propagate, sweep keys stay authoritative.
+- No-PVC aggregate harvest behavior: the operator mirrors sidecar paths at the results root.
+
+Out of scope: full kopf handler registration and HTTP router rendering; see sibling files
+``test_sweep_child_rollup.py``, ``test_aggregate_fetch.py``, and UI sweep-detail tests.

+"""Tests for the sweep-aggregate harvest handler.
+
+Covers ``fetch_sweep_aggregate_to_disk`` — the operator-side helper that pulls
+the sweep-controller's parent aggregate + children.json + per-strategy
+confidence payload off the sweep-controller pod's results-sidecar and onto
+the operator's PVC, before the JobSet (and pod) is deleted on success. The
+data lives only on the sweep-controller's emptyDir, so the harvest is the
+last chance to capture it.
+
+Key invariants:
+- Transport never advances ``latest.txt``; the kopf completion handler owns
+  that commit after validating the full archive bundle.
+- The result reports both ``downloaded`` and ``listed`` so the caller can
+  detect a PARTIAL harvest (some advertised files never landed) and keep the
+  JobSet alive for a re-harvest instead of destroying the only other copy.

+Focuses on:
+- JSON-patch atomicity when concurrent monitor/lifecycle handlers claim completion.
+- Annotation-map races where unrelated writers mutate metadata between snapshot and patch.
+- Conflict re-read behavior for stale bodies, missing live claims, and apiserver errors.
+- Retryability: failed claim attempts must not poison the in-process fast-path cache.

+Out of scope: result-file parsing and index writes; see

+"""Tests for ``aiperf.operator.handlers._completion_fetch``.
+
+Covers the low-level result-fetch retry/backoff machinery:
+
+- ``_snapshot_bytes`` — directory size accounting with vanishing-file tolerance.
+- ``_split_downloaded`` — checkpoints vs final-file partitioning.
+- ``_merge_downloaded`` — sorted-set union semantics across retry attempts.
+- ``_IncompleteResultsError.to_fetch_result`` — error-message phrasing per
+  partial-progress shape.
+- ``_update_progress_streak`` — stagnation counter + raise-on-stall contract.
+- ``_try_fetch_once`` — single-attempt exception-to-tuple translation.
+- ``_fetch_with_progress_aware_retry`` — progress-aware retry loop, including
+  the cancellation short-circuit branches.
+- ``_run_fetch_loop_safely`` — failure-to-ControllerFetchResult coercion.
+- ``_download_final_and_sidecar`` — primary-then-sidecar download orchestration
+  with key-file / port-collision short-circuits.
+- ``_fetch_once_into_state`` — single fetch attempt that mutates shared state.
+- ``fetch_results_with_retry`` — public entry: ValueError on missing inputs,
+  dest_dir derivation from body, cancellation handling.

+JSON export — but ``status.summary`` stayed empty. ``aiperf kube list``

+THROUGHPUT/LATENCY columns, so blank summary meant blank columns even

+of the ``latest.txt`` pointer; when omitted, the legacy "latest" behavior

+"""Regression tests for the JobSet-not-found phase-stomp race.
+
+Race shape: ``handle_completion`` writes ``phase=Completed`` then
+``_maybe_delete_jobset_after_success`` deletes the JobSet. A subsequent
+``monitor_progress`` timer tick fires with a *stale* body snapshot
+(kopf's local cache hasn't yet caught the watch event for our own
+patch), sees a non-terminal ``current_phase``, fetches the JobSet,
+gets a 404, and ``_reconcile_missing_jobset`` would historically stamp
+``Phase.FAILED`` over an already-Completed CR.
+
+The defenses are in :func:`_reconcile_missing_jobset`:
+    1. The completion-claim annotation on the body is authoritative —
+       ``try_claim_completion`` stamps it BEFORE ``handle_completion``,
+       and only the success path deletes the JobSet, so claim+404 means
+       "success handler owns this CR".
+    2. Fresh-read failure must not stamp FAILED (apiserver hiccup is
+       not evidence of benchmark failure).
+    3. Fresh body's annotations are re-checked too — a peer operator
+       pod (HA) or concurrent tick may have stamped the claim between
+       our body snapshot and the fresh read.
+
+The claim annotation is metadata, i.e. writable by anyone who can edit the
+AIPerfJob, so defenses 1 and 3 only honour a claim whose timestamp is present,
+parsable, and younger than ``_claim_trust_window_sec()``. An older or forged
+claim must not be able to suppress the FAILED stamp forever.

+"""State-machine and edge-case tests for the AIPerfJob monitor handler.
+
+The monitor handler observes JobSet/Pod state and patches the CR's
+``status.phase`` to drive the AIPerfJob lifecycle:
+
+    Pending -> (Queued) -> Initializing -> Running -> Completed/Failed/Cancelled
+
+This file targets edges not covered by the existing happy-path tests:
+
+* Forward and refused phase transitions (e.g. completed-CR no-op).
+* Job-timeout escalation (FAILED + JobSet delete).
+* JobSet terminal conditions: Completed never claims, non-True ignored.
+* Pod-state aggregation: all-pending, mixed, all-failed, controller-cascade.
+* Bootstrap / reconciliation paths after operator restart.
+* Orphan-claim recovery gating (only fire when the benchmark is done).
+
+Mocking strategy:
+    * ``k8s_client`` replaced with an ``@asynccontextmanager`` yielding
+      a ``MagicMock`` ApiClient (avoids ``AsyncMock`` quirks around
+      ``__aenter__``/``__aexit__``).
+    * ``CustomObjectsApi`` patched to a ``MagicMock`` whose async methods
+      are ``AsyncMock`` instances.
+    * ``try_claim_completion``/``handle_completion`` etc. are monkeypatched
+      on the monitor module symbol; cancellation is driven through the real
+      ``client_cache`` helpers.
+    * Real ``kopf.PermanentError`` / ``kopf.TemporaryError`` only where
+      the production code raises them — transient API errors (ApiException,
+      aiohttp.ClientError, etc.) are re-raised as ``kopf.TemporaryError`` after
+      clearing partial patch writes; escalation tests therefore assert both the
+      raised error type and that patch.clear() was called.

+
+When the operator pod crashes after ``_maybe_delete_jobset_after_success``

+Without a fallback, ``_benchmark_appears_complete`` returns False and
+orphan-claim recovery never fires — the AIPerfJob CR sticks at phase

+    expected to be unavailable. The product already degrades to PVC-only on
+    its own budget; the test just shortens that budget so the degradation is
+    fast and deterministic instead of inheriting the 10s production default.
+
+    The budget has to be patched as an attribute: ``OperatorEnvironment`` is a
+    module-level singleton built at import time, so ``monkeypatch.setenv`` on
+    ``AIPERF_RESULTS_K8S_INIT_TIMEOUT_SEC`` here would be inert.
+
+    The outer timeout is a backstop for a genuine hang, deliberately well above
+    the product's budget -- when it is the tighter of the two it preempts the
+    product's own degradation path and every test using this fixture errors.

+"""Adversarial regression-locking tests for AIPerfSweep handlers.
+
+Locks in the recently-fixed bugs:
+
+1. ``child_rollup.on_child_phase_transition``: ``PartiallyFailed`` is bucketed
+   as ``failed``, not ``in_flight``; ``_read_parent_status`` guards against
+   clobbering terminal parent phases with ``Aggregating``; the API patch is
+   sent with ``_content_type="application/merge-patch+json"``; the handler
+   accepts arbitrary kopf-extra kwargs (``**_: Any``).
+2. ``lifecycle.cancel``: terminal parent phase makes the handler a no-op even
+   when ``spec.cancel=True``; ``spec.cancel=false`` clears any prior
+   ``Cancelling`` condition (sticky-flag fix); the handler accepts arbitrary
+   kopf-extra kwargs.
+3. ``create.handle``: accepts arbitrary kopf-extra kwargs.
+4. Sweep-identity fencing: a child only counts toward a parent when its
+   controller ownerReference AND its sweep / sweep-uid / sweep-run-epoch
+   labels all match, and the triggering child is re-read from the apiserver
+   before any parent mutation so a delayed event from a previous run of a
+   same-named sweep cannot corrupt the current one.

+The adaptive planner records its feasibility verdict, its stopping reason, and

+(``exporters/search_history.py``). These tests lock the projection of that file
+onto the detail route, and — more importantly — lock the fail-soft contract: a

+fail the request, because the file is written with a bare ``write_bytes`` and is

+"""One bad record must not destroy every artifact on a local run.
+
+BufferedJSONLWriterMixin latches a sticky ``_write_error``, so a single
+non-serializable record or a transient ENOSPC makes ``flush_buffer`` raise for
+the rest of the run. Propagating that out of ``_finalize_local_artifacts`` cost
+the run ``profile_export.jsonl`` *and* the CSV/JSON/console exports and exited
+1, where main lost the one line and kept every artifact.
+
+Under the operator the tradeoff inverts: a written results marker is
+authoritative, so a partial export must fail closed as an ``ExceptionGroup``
+and surface as a failed CR. ``_finalize_local_artifacts`` therefore branches on
+``RecordProcessor._is_group_managed_mode``, which every test here stubs
+explicitly -- ``MagicMock(spec=RecordProcessor)`` otherwise auto-creates it as a
+truthy Mock and silently drives every case down the fail-closed path.
+``CancelledError`` is shutdown, not a degraded artifact, and propagates in both
+modes.

+"""A failed finalization must terminate the run, not hang it.
+
+``_finalize_and_process_results`` is launched with ``execute_async`` -- a bare
+``create_task`` whose exception nobody retrieves, with no global asyncio
+exception handler behind it. The controller's join barrier only closes on
+``ProcessRecordsResultMessage``, so an exception escaping this task means the
+CLI waits forever with every metric computed and nothing written. These tests
+pin that a failure still produces a published, explicitly-failed result.
+
+Companion coverage here:
+
+* the GPU telemetry drain timeout is marked non-fatal so a dead telemetry
+  container cannot suppress a valid inference export;
+* ``AIPERF_RECORD_CHECKPOINT_INTERVAL=0`` genuinely disables the checkpoint
+  task instead of spinning the background loop on ``asyncio.sleep(0)``;
+* a stall-forced finalization is stamped onto the exported artifact.

+"""The consumer half of clock-offset correction.
+
+Task 11 shipped the estimator; without a reader the measurement never reaches
+a record and cross-pod timestamps stay skewed. Every ``RequestRecord`` leaving
+a worker carries the offset that was current when it was emitted, so downstream
+can map worker wall-clock into the controller's frame.
+
+Sign convention (get this wrong and correction doubles the error instead of
+removing it): a sample is ``received - issued``, so a worker clock running
+*ahead* of the controller yields a *positive* offset, and ``correct_timestamp``
+SUBTRACTS -- ``controller_time = worker_time - offset``.
+
+What is stamped is ``ClockOffsetTracker.correction_ns``, not the raw
+``offset_ns``: the raw sample is ``skew + transit``, so stamping it biases every
+exported controller-frame timestamp one network hop early.

+"""Deferred FORK-parent eviction must be order-independent and bounded.
+
+``fork_refcount`` alone is not a safe eviction trigger: FORK children arrive
+one credit at a time, so the refcount returns to 0 between siblings. Evicting
+the parent on the first join stranded every later sibling with an empty
+history (``seed_from_parent`` silently no-ops on a missing parent), which
+reads as a model regression rather than a cache bug.
+
+The complementary hazard is the opposite one: a parent left in
+``pending_fork_eviction`` forever when its children never reach this worker
+(failed spawn, or a sticky miss routing them elsewhere). Nothing collects
+those, and the LRU overflow pass skips them, so they defeat the cache cap.

+"""Adversarial tests for the WGM tokenizer-distribution flow.
+
+These tests reproduce real production bugs that the existing unit tests
+missed and that only surfaced after deploys to DGX:
+
+1. ``_publish_group_message`` filtered to ``ServiceType.WORKER`` only,
+   so the sibling-container ``RecordProcessor`` never received
+   ``GroupTokenizerReady`` even though it had registered as a peer.
+   Symptom: WGM logs "prefetch complete" with the bundle on disk, but
+   the RP container's parser is stuck forever in
+   ``self._tokenizer_ready.wait()``.
+
+2. WGM's ``_prefetch_tokenizers`` passed the full
+   ``runtime.dataset_api_base_url`` (which ends in ``/api/dataset``) to
+   ``download_tokenizer``, producing a ``/api/dataset/api/tokenizer/...``
+   URL that 404'd. The RP/parser path used to do the strip in
+   ``resolve_tokenizer_load_target``; after the architecture refactor
+   that helper went away and the strip got lost.
+
+3. Silent hangs: ``_prefetch_tokenizers`` had no log statements between
+   "task scheduled" and "transient error", so a hang in the middle was
+   invisible from kubectl logs alone.

+"""Assert the AIPerf operator's code-side defaults match the Helm chart's values.
+
+Without this gate, code-side and chart-side ports / URLs / namespace defaults
+drift silently — the kind of mismatch that caused round-1's BASE_URL pointing
+at port 8080 (where there's no FastAPI), round-3's metrics port not being
+exposed on the Service, and the round-5 ``RESULTS_SERVER_PORT`` env-var gap.
+
+What this script asserts:
+
+1. ``OperatorEnvironment.SERVICE.BASE_URL`` default port matches
+   ``Values.resultsServer.port`` — round-1 collapse depends on this.
+2. ``OperatorEnvironment.METRICS_PORT`` default matches
+   ``Values.operator.metrics.port`` — round-3 ServiceMonitor + Service
+   wiring depends on this.
+3. ``aiperf.kubernetes.results_operator.RESULTS_SERVER_PORT`` default
+   matches ``Values.resultsServer.port`` — round-5 CLI port-forward
+   target needs to match what the chart binds.
+4. ``DEFAULT_OPERATOR_NAMESPACE`` constant matches the namespace every
+   ``helm install``/``helm upgrade`` command in the chart README's fenced
+   code blocks targets.
+
+Runs as a unit-scope check: pure import of the settings classes + a YAML
+parse of ``values.yaml``. Designed to be called from pre-commit and CI.

+Exit codes:
+    0 — all consistent

+"""Fetch, verify, and pin the hand-vendored third-party JS/CSS assets used by
+the operator UI and the API server's dashboards.
+
+These UIs deliberately have no build step (no bundler, no ``node_modules``):
+each browser-runtime dependency is a single upstream file, downloaded once,
+pinned to an exact version, and served as a static asset via a browser
+import map or a plain ``<script>``/``<link>`` tag. This script is the audit
+trail for that: MANIFEST records exactly which upstream URL and SHA-256 each
+vendored file came from, so "what third-party code does this ship and where
+did it come from" is a command, not an archaeology exercise.
+
+This intentionally does NOT use ``tools/generate_python_attributions.py`` /
+``licenses.toml`` machinery -- that pipeline derives its inventory from
+pip-licenses metadata, which has no concept of a hand-copied JS file. Feeding
+these entries into the same third-party-attributions output is a reasonable
+follow-up, but is a separate change.
+
+Usage:
+    tools/vendor_ui_deps.py --check           # offline: verify vendored files match MANIFEST
+    tools/vendor_ui_deps.py --update           # re-fetch every entry, verify hash, write to dest
+    tools/vendor_ui_deps.py --update NAME...   # re-fetch only the named entry/entries
