fix(f1): resolve callers, delivery and closure from live state, not the stale registry record - #466
Conversation
…he stale record The registry marks live agents `done` within minutes (#408). Four ratified contracts read that record as primary truth and broke together: - U6: `resolveCurrentCallerAgent` filtered terminal records out, so a live lead was invisible as a caller and the child it spawned recorded `parent_agent_id: null`. The #378 worker guard (`callerIsWorker`) could never fire for a stale-done caller and silently no-opped. - U8/#404: `send_to` gated on the route's registry state, returning `delivery:"failed"`, `terminal:true` to an agent sitting at a live prompt — contradicting send_to's own published promise of a nonterminal queued receipt. A retryable refusal was also flattened into a terminal failure. - P11 Contract C: `assessHarvestability` passed `agent.state` to `resolveClosureState`, so a working agent read `closure:"artifact_missing"` — which P11's own table means "route a reviewer NOW". New `src/live-agent-state.ts` owns the one screen->state rule (agent-health now imports it instead of re-deriving it) and the rules for when live evidence may overturn the record: - `working` / bare-shell always override: the record cannot know either. - `ready` may clear a stale `error` but never a `done` — a finished worker sits at a ready prompt too, so overriding there would erase done-detection. - Deliverability is a separate question from closure and only ever WIDENS what the record allowed, and only over a TERMINAL record: a `booting` pane may still be receiving its launcher line. Consumers wired to it: caller resolution (terminal state is now an ordering signal, never an exclusion), the send_to interactive gate, and closure via a live-state resolver injected into the engine. `AgentDiscovery.cachedScan()` exposes the last scan synchronously so none of this adds I/O to a caller path. Does not touch #408's root cause — this makes the consumers immune to it. Contract changes (deliberate, tests updated): - send_to/send_to_agent return a nonterminal queued receipt naming the reason instead of an error when the interactive gate refuses retryably. - A `done` record whose pane still reads WORKING now reports closure `pending`, not `artifact_missing`.

📝 WalkthroughWalkthroughThe change adds shared live-agent state resolution from screen evidence, cached discovery observations, and registry state. Server delivery, caller identity, lifecycle harvestability, closure, and health decisions now use the resolved state. Retryable delivery failures return queued receipts. ChangesLive agent state integration
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The change improves live-state handling, but delivery can still skip required submit verification, healthy agents can appear degraded, and permanently undeliverable messages may remain queued indefinitely without a terminal outcome. These bounded production risks should be fixed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
A ready screen on a done record now marks health degraded.
screenConfirmedAgentState returns "ready" when control_state === "ready" and the agent type is known. For the stale-done population this PR targets, Lines 461-469 then add registry_screen_disagreement.
issueSeverity softens that code to "info" only when context.screenActive is true, and screenActive is input.screen_status === "working" || "thinking" (Line 428). A ready prompt is neither. The default severity of "degraded" therefore applies, and deriveStatus reports status: "degraded" for every agent with a stale done record and a healthy ready prompt.
That is the normal case after issue #408, so health degrades on evidence that the agent is fine. Treat a screen-confirmed non-error state as informational disagreement.
🐛 Proposed fix: soften the disagreement when the screen confirms a healthy state

Confirm the shell-fallback condition stays aligned with the shared classifier.
Lines 450-452 re-derive the shell condition locally, while screenConfirmedAgentState applies the same rule internally to return "error". Two copies of one rule can drift.
Consider deriving screenIsShell from the classifier result:
♻️ Proposed refactor
- const screenIsShell =
- input.screen_control_state === "shell" &&
- input.screen_agent_type === "unknown";
+ const screenIsShell = screenConfirmedState === "error";This is only equivalent while "error" has exactly one producer in the classifier. Verify that before applying.

Bound retries for queued deliveries. queueDelivery reuses the existing delivery_id and does not create a duplicate receipt. However, drainDeliveryQueue retries RetryableDeliveryError indefinitely without a terminal transition. A permanently undeliverable target leaves wait_for(delivery_id) without failure evidence until its caller timeout.

Add lifecycle no-op methods to LiveSurfaceClient.
When a sweep publishes status for a registered agent, the missing setStatus method causes a TypeError. startSweep catches the error and retries, but the sweep cannot reconcile the fixture. Add no-op implementations for log, setStatus, setStatuses, clearStatus, setProgress, clearProgress, and notify.

Widen the makeAgent overrides so call sites do not need as any.
overrides is typed Partial<AgentRecord> & Pick<AgentRecord, "agent_id" | "surface_id">, yet Lines 212, 288, and 316 cast through as Partial<AgentRecord> as any to pass task_done_detected_at, report_path, and done_marker. Those fields exist on AgentRecord (src/server.ts reads report_path and done_marker, and makeServerAgentRecord sets task_done_detected_at).
Set the fields as explicit defaults in makeAgent and drop the casts. The casts currently suppress type errors for misspelled field names.

closure:"pending". ✓
Fallback correctness (brief §2) — checked all three consumers; no inversion
With no live observation (cachedScan() null, read_error, or an unbound row), resolveLiveAgentState
returns source:"registry", stale_registry_state:false, and every consumer degrades conservatively:
isLiveActive requires source==="screen" so closure falls back to the record; isLiveDeliverable reduces
to the old registry gate exactly; caller resolution is the one that widens, and it widens on purpose
(the call itself is the liveness evidence). Nothing treats "unknown" as "alive forever". Good.
I also verified the claim in the AIDEV-NOTE that screenObservationForRecord uses "the same binding rule
list_agents uses" — it is character-for-character the rule at server.ts:13540-13552, including the
kiro → agent_type:"unknown" mapping (:13566, :13584). That claim is true, and it mattered: a looser
match here would let an unrelated pane decide an agent's state.
Performance (brief §4) — measured honestly
- Zero new screen reads on any path.
cachedScan()is cache-only (returns null past the 2000 ms TTL and
never triggers I/O);send_toreuses thefreshOccupantscanassertAgentRouteHasTuialready took;
agent-healthis a pure refactor. Inlist_agents,discovery.scan(true)at:13688populates the cache
the closure probe then reads, so state and closure in one response come from the same rows. - One new synchronous fs read, honestly:
assessHarvestability's pre-closure branch now calls
readClosureGoalContract(agent-engine.ts:1765), whichreadFileSyncs the goal file — but only when
agent.goal_fileis set. Atdetail:"full"assessHarvestabilityruns twice per agent
(server.ts:13621and:13632), so worst case is 2 small local reads per non-doneagent per call.
Not a screen read, not an amplification of the Tool-usage failure rate is the product's biggest defect: 9.3% errors, 21% deprecation noise, read_screen at 29% of all calls (measured) #403/MEASURED: cmuxlayer responses burned ~277k tokens across 945 calls — full per-field audit #425 family — but it is new, and memoizing the
assessment per request would erase it.

verify_submit still reads the registry record, so the newly-widened case delivers UNVERIFIED
— server.ts:11060:
verify_submit:
args.press_enter &&
(args.allow_busy || INTERACTIVE_AGENT_STATES.has(deliveryRoute.state)),deliveryRoute = route (:11020) — the registry state. The class this PR newly admits is exactly
registry terminal + screen ready + allow_busy:false, so for every one of those deliveries this
evaluates false, and the submit-verification helper short-circuits (:4699) to
{submit_verified: null, delivery: "submitted"} — a terminal success receipt with no proof the Return landed.
The comment three lines above says why that is not acceptable: "A short relay (the common agent-to-agent
case) to a frozen terminal must be caught, never reported as ok."
Before this PR that combination was refused outright, so this is exposure the widening creates, on the lane's
own non-negotiable path — the same receipt lie with the sign flipped: false failed → possible false ok.
Knock-on: with submit_verified !== true, markAgentWorking never fires (:11071), so the poisoned record
is never corrected and every subsequent send repeats the unverified path.
Fix is one expression — gate on the live state you already resolved eleven lines earlier
(liveRouteState, :10982), e.g. args.allow_busy || isLiveDeliverable(liveRouteState) — plus a test that
a stale-done/screen-ready send comes back submit_verified: true, not null.
Recommended, not blocking (3)
- The caller-ordering claim is asserted in a comment and tested nowhere. The AIDEV-NOTE says "the
live-first ordering still lets a genuinely live record win a recycled surface (spawn_agent: role is inferred from the CLI/launcher, so every Claude reviewer lands in the orchestrator column #378 MEDIUM-A)" — true by
construction of the four tiers, but no test pins it. Two records bound to one surface (one stale-done,
one live) asserting the live one becomes the parent is ~15 lines and locks the tier order against a
future reorder. - Tier 4 (
records.find(matchesSurfaceId)over terminal records) can mis-attribute a parent.
surface_idis a recyclable ref — this repo guards it explicitly elsewhere ("surface recycled",
server.ts:10962) — so a dead worker's record whose ref got reused, with no live record bound, now claims
to be the caller, and spawn_agent: role is inferred from the CLI/launcher, so every Claude reviewer lands in the orchestrator column #378 then forces the new pane's children toworker/rightoff a corpse. Tier 3
(uuid) is safe; consider bounding tier 4 bysurface_observer_id+ record recency, or dropping it. - The retryable receipt now never terminalizes.
queueDeliverysetsverify_deadline_at: null
(agent-engine.ts:6657+) and the drain backs off to a 30 s cap forever (:7121-7130), failing only if the
agent record disappears (:7050). Correct per this lane's charter — the dead-surface cases stay terminal
via the non-retryableassertAgentRouteHasTuithrow, and the gate at:10998is the only
RetryableDeliveryErrorthrow site in the whole server — it fires before any text is typed, so requeueing
carries no double-type risk (I checked; that was my first worry about this path). But a target stuckbootingforever now yields a receipt a lead can wait on
indefinitely. Worth an issue, not a hold.
PREDICTION — judged
Half right, and the half it missed is the required fix. The predicted objection (consumers keying off
isError must now read delivery_state/terminal) is real and correctly pre-empted — I have no complaint
about the widened contract itself, the old shape was the lie. But the prediction frames the widening's cost
as downstream consumers, and its actual cost is upstream inside the same function: the gate it widened
hands those deliveries to an unverified submit path. The residual-risk note (state: ready beside
closure: artifact_missing) is accurate and correctly judged as coherent-though-odd — that pairing reads
"finished, at its prompt, no artifact", which is exactly what a lead needs to see. "Not attempted: #408" is
honest and holds.
Everything else about this lane is the right shape: one module owning one rule, working/bare-shell as the
only overrides, ready deliberately too weak to erase done-detection, delivery separated from closure, and
registry retained as provenance rather than discarded. Fix the verify_submit line and this is a merge.
— cmuxlayerClaude-reviewer-466 (worker) · claude-code/claude-opus-5
Reviewer's one required fix. `verify_submit` still read the registry record:
args.press_enter && (args.allow_busy || INTERACTIVE_AGENT_STATES.has(deliveryRoute.state))
`deliveryRoute` is the registry route, so for exactly the class this lane
newly admits -- registry-terminal + screen `ready` + allow_busy:false -- it
evaluated false and the submit-verification helper short-circuited to an
unproven success. That is the same receipt lie with the sign flipped: a false
`failed` replaced by a possible false `ok`, on the lane's own non-negotiable
path. Gate it on `liveRouteState`, resolved eleven lines earlier.
Regression test: a stale-done/screen-ready send now returns
`submit_verified: true` and `delivered: true`. The first test's assertion was
corrected with it -- that receipt is now terminal because it is a PROVEN
success, and the contract was always "never a terminal FAILED receipt".
Also from the review (recommended items):
- Added a test pinning the caller-resolution tier order: a live record beats
a stale-done one bound to the same surface.
- Recycled-surface caller attribution (#468): investigated, NOT fixed. The
obvious guard -- compare the live pane's CLI to the record's, as
deliverAgentInput does -- cannot fire, because `registry.listMerged`
rewrites `record.cli` from the live pane before caller resolution runs
(verified: claude -> codex after one list_agents). Shipping it would have
added protective-looking code that never triggers. AIDEV-TODO + issue.
- Unbounded retryable queue (#467): filed, not held.
Known residual, documented in the test: `markAgentWorking` only transitions
from `idle`, so a verified send still does not correct a poisoned `done`
record. Widening that would erase done-detection whenever a lead pings a
finished worker -- a separate state-machine decision.

…ord (#478) * fix(f1b): wait_for and watch resolve from live state, not the raw record F1 (#466) converted callers, delivery and closure to `resolveLiveAgentState` and left the two paths a lead actually monitors with reading the registry record raw. #473 — `wait_for`'s terminal short-circuits read `registry.get()` directly, so a #408-poisoned `done` returned `{state:"done", error:"Agent has already completed", elapsed:0}` for an agent mid-`brew install`, while the same response's own health block said `reconciled_state:"working"`. Every termination decision in `waitFor` now reads the live-resolved state — the entry short-circuits, the retroactive evidence gate, the sweep's fail-fast, and the timeout report — and the top-level `state` carries the reconciled value. Gating only the entry would have moved the false completion one poll later, so the sweep is gated with it. With no live probe wired the resolution IS the record, so an unprobed engine is unchanged. #472 — `watchAgentObservation` answered "does this agent exist?" with one in-memory registry lookup AND a successful screen parse, so a transient read failure, an unreconstituted record, or a booting pane all became `exists:false` and a hard `WatchArmError` saying the agent does not exist — for an agent `send_to` delivered to and verified in the same second. The record now decides existence (registry, then the state dir), the screen only refines what the agent is doing, a read failure is retried once and reported as a read failure, and a booting or unparseable frame arms and lets the predicate resolve. Only positive evidence the surface is gone (dead, evicted, bare shell) returns `exists:false`, and the refusal names what was observed instead of asserting absence. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(f1b): the wait buys its own live evidence instead of hoping the cache is warm Round 2, reviewer finding A (BLOCKING). Round 1 read the live-resolved state everywhere it decides, and then depended on `discovery.cachedScan()` for that state -- which is evidence-free once the scan is 2000ms old, and nothing on the `wait_for` path refreshes it. For a lead whose next action is `wait_for` the cache is ordinarily cold, so the entry short-circuit resolved to the poisoned record and returned the reported bug byte-for-byte; warm at entry, it moved to the sweep tick two seconds later. Mock-green, not live-green: the round-1 probe modelled the resolver's shape and never its availability. So the engine can now FORCE evidence. `setFreshLiveStateProbe` takes an async single-surface probe (server-wired to `discovery.scanTarget`, not a fleet `scan`), `refreshLiveState` reads one screen and memoizes the resolution for LIVE_EVIDENCE_TTL_MS, and `liveStateOf` answers from that memo -- dropping it when the record moves, so a wait never answers with evidence about the agent's past. `waitFor` buys evidence at entry, on a 2000ms sweep cadence, and once more at timeout. Payload: one screen read per agent at entry, one per 2s while waiting, one at timeout -- bounded and asserted, not one per 1000ms tick. That memo also closes the second symptom reported live: P11 closure reads `liveStateOf`, so a working child rendered `closure:"artifact_missing"` beside `state:"working"` in one payload. The closure in a wait's own reply is now computed from the evidence that wait bought. Only positive evidence of ACTIVITY may overturn a terminal record (`terminationStateOf`). A ready prompt is where a finished worker sits and a pane reclaimed by a bare shell says nothing about whether the task completed; without this rule `wait_for(done)` reported `error` for an agent that genuinely finished on a surface that was later reclaimed. Finding B: the ready-evidence gate no longer decides from the raw record -- it opens when either the record or the live state is in the pre-target state, and additionally requires the record to be able to REACH the target, so it does not buy a screen read per tick for a transition `VALID_TRANSITIONS` forbids. Stated plainly in the code: for a `done`-poisoned record the wait still runs to timeout, because `VALID_TRANSITIONS.done` is empty. It fails safe; the other half is #408. Nits: `live` is computed where it is used; the read-failure fallback in the watch observation is documented as a decision, not an accident. Adds the negative watch-arm coverage the review asked for (bare shell still refuses). Two pre-existing expectations encoded the pre-F1b contract for a registry-done agent whose screen shows work in progress; both are updated with the reason, and neither test's own subject changed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(f1b): one row, one state rule — and artifact_missing takes evidence Round 3, from golemsClaude's live report: five specimens on v0.4.47 with the F1 fix present, one spawned two minutes earlier, each rendering `closure:"artifact_missing"` while the same row's `state` said `ready`. Two rules were deciding one row. The row's `state` came from agent-health's reconciled state -- the raw `screenConfirmedAgentState` verdict -- while `closure` came from `isLiveActive(live) ? live.state : agent.state`, where `ready` may not overturn `done`. So a fresh agent at a live prompt whose record #408 had flipped published a live state and a terminal closure side by side, and the alarming one won. `closureStateOf` is now that one rule, in one place, with two carve-outs about EVIDENCE rather than about which field is rendering: activity always wins, and a `done` the agent EARNED survives a ready prompt so a genuinely finished worker's deadlock signal keeps working. What no longer survives is a `done` with nothing behind it. And `artifact_missing` now takes positive done evidence. It is not a description, it is an alarm -- P11's table reads it as "route a reviewer NOW" -- so `resolveClosureState` requires `doneEvidence`, sourced from the evidence channel this payload already reports (`done_source !== "none"`: a done signal seen on the screen or in the harness transcript). A record that flipped is not a task that finished. That closes the cold-cache shape too: with no live evidence anywhere, a bare `done` record can no longer fire the alarm on its own. The F1 fixture asserting artifact_missing at a ready prompt carried no done evidence, which made it indistinguishable from the live specimen; it now carries `task_done_detected_at`, and its sibling -- same screen, same missing report, no evidence -- asserts `state:"ready"` beside `closure:"pending"` through the real `list_agents` tool.

Resolutions, per its report: - src/agent-engine.ts: main's assessHarvestability(agent,{live}) input and its isLiveActive(live) ? live.state : agent.state terminal rule, plus the merged positive-done evidence rule; #478's fresh-probe wait/watch kept. - src/coordination-paths.ts: main's concise form of the same behaviour, keeping the doneEvidence contract and the verified -> artifact_missing -> pending order. - tests/coordination-paths.test.ts: main's expanded fixtures, both polarities. Two real merge regressions fixed (t1b-closure-probe-divergence, sidebar-sync): #478's pre-merge closureStateOf made a ready-screen/record-done worker nonterminal before report verification; switched that one line to main's #488 rule.

Deleting them leaves the suite byte-identical -- they compiled only because tsconfig has no noUnusedLocals. The 20-line AIDEV-NOTE above closureStateOf still asserted "the one rule a response may use", so the next reader greping for the closure rule found an authoritative comment on unreachable code. Round 3's fix 1 was superseded by #488's doneEvidence gate in the merge. 2. Two both-sides-kept conflict artifacts from the main merge, invisible to `bun run typecheck` because tsconfig excludes tests/ (now #502): - coordination-paths: doneEvidence twice, same value, harmless. - f1-live-state-truth: task_done_detected_at twice with DIFFERENT values; the second silently won, so a merge decision was being made by JS object ordering. Kept the F1b round-3 value and the comment explaining why that worker EARNED its done, which is what the fixture is for. Suite 138 files / 3194 passed / 1 skipped; typecheck exit 0; both TS1117s gone under direct tsc.

Lane F1 — one stale registry field silently disabled four contracts
Finding F1 (
docs.local/plan/stability-v2/phase-12/evaluation.md): the registry marks live agentsdonewithin minutes (#408). Everything that read that record as primary truth broke together. This lane does not fix #408's root cause — it makes the consumers immune to it.The four consequences, and what changed
resolveCurrentCallerAgentfiltered terminal records out (server.ts:497,:3541-3556), so a live lead was invisible and its child recordedparent_agent_id: nullcallerIsWorkercould never be true for a stale-done caller — the fix for the 3×-recurring "reviewer in the lead column" class no-oppedsend_toreturneddelivery:"failed",terminal:trueto an agent at a live prompt (ledger row 4). Retryable refusals were flattened into terminal failuresagent.statepassed toresolveClosureState(agent-engine.ts:1723,1847) made a working agent readartifact_missing— "route a reviewer NOW"The change class

src/live-agent-state.tsowns one screen→state rule (agent-health.tsnow imports it instead of re-deriving it) plus the rules for when live evidence may overturn the record:workingand bare-shell always override — the record cannot know either.readymay clear a staleerrorbut never adone. A finished worker sits at a ready prompt too; overriding there would erase done-detection for every agent that returns to its prompt.isLiveDeliverableonly ever widens what the record allowed, and only over a terminal record — abootingpane may still be receiving its launcher line.AgentDiscovery.cachedScan()exposes the last scan synchronously, so none of this adds I/O to a caller path. With no fresh evidence it degrades to the record with explicitsource: "registry"provenance.Deliberate contract changes (existing tests updated, not bent)
send_to/send_to_agentreturn a nonterminal queued receipt naming the refusal reason instead of an error when the interactive gate refuses retryably. The engine drains it when the target is ready.donerecord whose pane still reads working now reports closurepending, notartifact_missing— that is the F1 ruling applied toget_agent_statetoo, so one existing test was re-seeded to detach its pane (the record then really is the only evidence, which is the case it was written to describe).Tests
tests/live-agent-state.test.ts(10) — the rule itself, including both directions of thereadycase.tests/f1-live-state-truth.test.ts(5) — the live-probe shape: send_to to a screen-idle registry-done agent returns nonterminal; a mid-turn target never resolves terminal; closure readspendingwhile working and stillartifact_missingwhen the screen confirms done.tests/server-agent-tools.test.ts— stale-done caller recorded as parent; spawn_agent: role is inferred from the CLI/launcher, so every Claude reviewer lands in the orchestrator column #378 guard fires for a stale-done worker caller.Verification

send_tocontract. A caller that treatedisErroras "target is dead" now getsok: truewith a queued receipt. That is the point — the old shape was the receipt lie — but any consumer keying offisErrorfor non-interactive targets needs to readdelivery_state/terminalinstead.list_agentsstill publishesstate.valuefromhealth.reconciled_state(which reconcilesreadyoverdone) whileclosureuses the narrower live rule. A row can therefore readstate: ready (screen)besideclosure: artifact_missing. That is correct — the agent finished and is at its prompt — but it looks like a disagreement at a glance. Unifying the two projections was outside this lane.done), per the brief.🤖 Generated with Claude Code

Touches caller identity, message delivery receipts, and P11 closure across the server and engine; consumers that treated
send_toisErroras “dead agent” must readdelivery_state/terminalinstead.Overview
Lane F1 makes control-plane behavior use live screen evidence when the registry wrongly marks active agents
done(#408), instead of treatingagent.stateas ground truth.A new
live-agent-state.tscentralizes screen→state mapping and when screen may override the record (working/ bare shell / screendonewin;readynever overturns registrydone;isLiveDeliverablecan still allow input to a live prompt over a terminal record).AgentDiscovery.cachedScan()exposes the last TTL-valid scan synchronously (no extra I/O). The server wires a live-state probe from that cache into caller resolution (terminal records are ordering hints, not excluded),send_togating and submit verification, andAgentEngineharvestability/P11 closure viasetLiveStateResolver.agent-healthreuses the same screen rule instead of duplicating it.Contract shifts: retryable interactive refusals on
send_toreturn a nonterminal queued receipt (not a terminalfailed); mid-turn targets follow the same pattern. Closure on a screen-working agent with a staledonerecord reportspending, notartifact_missing.Regression coverage adds
live-agent-state.test.ts,f1-live-state-truth.test.ts, and server-agent tests for stale-done callers/parent linkage.Reviewed by Cursor Bugbot for commit 928d5fb. Bugbot is set up for automated code reviews on this repo. Configure here.
