…enAiHookPolicy Reference slice for Mesh-LLM#1331: OpenAiHookPolicy only fired before-chat, with no way for a policy to observe the request actually dispatched or how a non-streaming chat completion ended (success/error/denial). Adds two additive, default-no-op hook methods wired into HookedOpenAiBackend's real dispatch path, plus a design note mapping what the real openai-frontend seam can and can't expose relative to Mesh-LLM#1331's acceptance criteria (notably: plugin-served models go through a separate raw-proxy path that never reaches OpenAiHookPolicy at all). Milestone 1 only: non-streaming chat completions, staged for discussion, no upstream PR.
…1331 design note Steven directive: map whether the terminal hook can (a) write an X-Capsule-Id-style marker into the response and (b) surface a later signed client ack, the mechanism that lifts acknowledged_receipt -> full_bilateral. Verdict, checked against source: can't on this seam. (a) the hook's response reference is immutable and ChatCompletionResponse has no extensible field unlike ChatCompletionRequest's `extra`; the only place that writes response headers today is frontend_lifecycle_middleware, which runs after every OpenAiHookPolicy call and outside OpenAiBackend entirely. (b) the ack is a separate later HTTP request and openai-frontend has no cross-request correlation. Both gaps are architectural, not just unbuilt.
…oxy path-2 coverage (Mesh-LLM#1331 M2) Closes both gaps M1's design note left open. Rung-ladder response leg: OpenAiHookPolicy gains capsule_marker_for_response, fired after a successful non-streaming chat completion. ChatCompletionResponse gains a #[serde(skip)] capsule_marker field; the router threads it through Response::extensions() (the same relay TerminalUsage already uses) so frontend_lifecycle_middleware can set X-Capsule-Id, mirroring how x-request-id is already set at that layer. Verified end-to-end through the real axum router, not just the Rust-level hook call. Path 2 (raw-proxy ingress) coverage: new plugin::openai_exchange module defines one wire envelope (OpenAiExchangeEnvelope) that both the typed frontend seam (path 1, via a new OpenAiExchangeHookBridge) and the raw-proxy ingress (path 2, via new call sites in try_route_plugin_model) publish onto the same openai.exchange.v1 mesh channel, so a plugin sees one unified stream regardless of which in-process Rust hook interface produced the event. PluginManager::broadcast_channel_message is new production code delivering to every plugin whose manifest declares the channel. cargo test/clippy -D warnings green (openai-frontend, mesh-llm-host-runtime, skippy-server); mutant-verified on every new must-fail check. Design note updated with both outcomes. Staged on fork branch only, no upstream PR.
…broadcast delivery) Three findings from the Mesh-LLM#1331 PR's coderbot review: 1. non_streaming_responses (the /v1/responses non-streaming leg) called chat_completion_with_context, which mints a capsule_marker via the hook seam, but translated the response into a new axum Response without carrying the CapsuleMarkerExtension over — so frontend_lifecycle_middleware never saw it and X-Capsule-Id was silently dropped for that leg while the terminal plugin event still reported the marker. Mirror the same extension-attach the chat_completion handler already does. Regression test drives the real router end-to-end, matching the existing /v1/chat/completions coverage. 2. Neither OpenAiExchangeEnvelope nor the transport ChannelMessage carried any id correlating an EffectiveRequest event with its Terminal event, so two concurrent exchanges on the same model were unpairable by a plugin. Mint a UUID exchange_id when each dispatch path admits the request (HookedOpenAiBackend::chat_completion_with_context for the typed-frontend path, try_route_plugin_model for the raw-proxy path), thread it through ChatExchangeRoute and the new on_chat_completion_terminal parameter, and propagate it into both envelopes and the channel correlation_id field. New paused-clock concurrency test proves pairing survives interleaved completion order, not just submission order. 3. PluginManager::broadcast_channel_message used `?` inside its per-plugin send loop, so one declaring plugin rejecting or losing its channel silently starved every later plugin in the BTreeMap of the event. Collect every plugin's send result, attempt all of them, then report one aggregate error naming only the failures. Extracted the aggregation into aggregate_broadcast_results with direct unit coverage, since exercising a live mid-stream plugin-transport failure needs a real subprocess this crate's existing plugin tests don't spin up. cargo test/clippy -D warnings green workspace-wide (openai-frontend, mesh-llm-host-runtime, skippy-server, and everything else in the workspace).

…clone, publish backpressure) Two non-blocking findings from i386's review on the Mesh-LLM#1331 PR: 1. hooks.rs's HookedOpenAiBackend::chat_completion_with_context cloned the effective request unconditionally, on every non-streaming completion, so on_chat_completion_terminal/capsule_marker_for_response would still have one to read after the backend call moved the original by value — even when the composed OpenAiHookPolicy never reads it there (the only real/live policy today, MeshAutoHookPolicy, doesn't). Added OpenAiHookPolicy::observes_dispatched_request (default true, preserving current behavior for any policy that doesn't override it) so HookedOpenAiBackend only clones when a policy actually opts in; MeshAutoHookPolicy opts out. When a policy opts out, the two post-dispatch hooks still fire, with a default/empty ChatCompletionRequest in place of the real one (ChatCompletionRequest now derives Default). New pair of tests proves both branches: a `true` policy sees the real model, a `false` policy sees an empty one. 2. openai_exchange.rs's OpenAiExchangeChannel::publish documents itself as fire-and-forget, but awaited PluginManager::broadcast_channel_message, which in turn awaited ExternalPlugin::send_channel_message -> send_unsolicited's outbound_tx.send().await on a bounded(256) per-plugin channel — genuine backpressure that could block the client's own request on a stalled plugin. Added ExternalPlugin::try_send_channel_message, a fire-and-forget sibling that uses try_send instead of send().await (and skips ensure_running, since a broadcast is not a reason to lazily start a plugin), and pointed broadcast_channel_message at it; left send_channel_message/send_unsolicited untouched since they back MCP/bulk-transfer/mesh-event delivery elsewhere, which may want the blocking backpressure this bridge must not have. broadcast_channel_message is exclusively used by this openai.exchange.v1 broadcast, so the change is scoped to exactly what i386 flagged. New test fills a bounded(1) queue with the receiver kept alive, confirms the blocking sibling still blocks (fixture sanity check) while try_send_channel_message returns immediately with an error instead -- both sides wrapped in an outer timeout so a regression to blocking behavior fails the test instead of hanging the suite. Did not take the 2001-line plugin/mod.rs split i386's review also mentioned -- out of scope per the task (mesh-llm-internal maintainability, not part of these two non-blocking notes). cargo test green: openai-frontend (195+7+2+1), mesh-llm-host-runtime (2560, 8 pre-existing ignores), skippy-server (478, 3 pre-existing ignores) -- each run standalone; running skippy-server alongside the other two crates in one `cargo test` invocation trips pre-existing native-runtime-library load-once state across parallel test binaries (unrelated to this diff, already noted as an environment characteristic by the M1/M2 branch history). cargo clippy --all-targets -D warnings clean across all three crates. cargo fmt clean on every file this commit touches (also cleaned up pre-existing fmt drift on plugin/mod.rs left by the prior coderbot-fixes commit, scoped only to that file, not a repo-wide reformat).

Needs revision. There are two lifecycle contract blockers inline.
Follow-ups:
- Validate capsule IDs before terminal publication so the hook and client can't disagree about the acknowledgement.
- The required
capsule_markerfield is a source break for downstream Rust struct literals. This needs a compatible shape or an explicit version boundary. - Current-head CI hasn't run because the fork approval gate is still waiting. This needs a green run before re-review.

Reviewed across all three layers (typed-frontend hook seam, raw-proxy ingress, plugin broadcast transport). Approving — this is a well-executed M1/M2 slice of #1331.
What I verified:
- Observer safety.
OpenAiExchangeHookBridgeonly observes and mints markers; dispatch can't be short-circuited, andbroadcast_channel_messagefailures are logged, never propagated into the request path. Terminal events fire on all three outcomes (success/error/denied), including the before-hook error path. - No backpressure leak into serving.
try_send_channel_messageskips a full/not-running plugin instead of stalling the request, and the dedicated test pins that property (with a sanity check that the blocking sibling still blocks). - Broadcast correctness. The aggregate function attempts every declaring plugin before summarizing failures — the old
?-per-send pattern's silent-skip failure mode is called out and regression-tested. - Correlation. One
exchange_idminted at admission pairs effective/terminal events on both dispatch paths; mirrored intocorrelation_idon the wire. - Header plumbing.
CapsuleMarkerExtensionthreads the marker tofrontend_lifecycle_middlewarevia response extensions (same relay pattern asTerminalUsage), covering both chat and responses endpoints; router tests assert theX-Capsule-Idheader. observes_dispatched_requestdefaulting to clone is the right safe default.
Two non-blocking notes:
- The fallback nonce
format!("fallback-{response.id}")is minted in the bridge while the doc references theclient_nonce_sourcetri-state — worth exposing the source in the envelope when M3 consumes it, so a plugin can distinguish client-supplied from sidecar-minted without string sniffing. - Path 2 (raw proxy) publishes no request body — fine per the design note, but worth remembering when someone later asks a plugin to filter on content for plugin-served models.

…ive, capsule id, manifest, nonce_source) Closes all six blockers @ndizazzo raised on PR Mesh-LLM#1437: 1. TerminalGuard (RAII, fires on Drop via tokio::spawn) guarantees exactly one on_chat_completion_terminal call per admitted exchange even when the backend future is dropped mid-flight (outer timeout / disconnect). Adds ChatCompletionOutcome::Cancelled and marks the enum #[non_exhaustive]. 2. ChatCompletionResponse is now #[non_exhaustive] with a from_parts constructor, so adding capsule_marker doesn't break downstream struct-literal construction (skippy-server's two call sites migrated). 3. capsule_id_is_valid() gates whether a hook-minted marker is ever attached to the response, using the same HeaderValue check the router already uses for X-Capsule-Id — so the client header and the plugin-visible terminal event can never disagree about the capsule id. 4. plugin_declares_mesh_channel/plugin_subscribes_mesh_event now use a new non-starting PluginManager::manifest_snapshot (backed by Plugin::manifest_snapshot, which never calls ensure_running) instead of manifest(), so the raw-ingress broadcast path no longer lazily starts a stopped plugin or blocks on its connect/init timeouts. 5. OpenAiExchangeEnvelope gains an explicit nonce_source (client_supplied / sidecar_generated_fallback), derived once from the request and shared by both the mint and the terminal-event publish, so a plugin no longer has to sniff the nonce's fallback- prefix. cargo build --workspace and cargo test on openai-frontend, mesh-llm-host-runtime, and skippy-server all pass.

…bot review) plugin/mod.rs was 2085 lines, over this repo's 2,000-line file limit (AGENTS.md). Move broadcast_channel_message, plugin_declares_mesh_channel, aggregate_broadcast_results, manifest_declares_mesh_channel, and their tests into a new owning module, plugin/channel_broadcast.rs, with no behavior change. mod.rs is now 1935 lines.

The exactly-once terminal mechanism (TerminalGuard, on_effective/on_chat_completion_terminal, capsule_marker_for_response, capsule-id validation) was reachable only from HookedOpenAiBackend, which nothing in production constructs. StageOpenAiBackend -- the real embedded backend -- called only before_chat_completion, and HookedOpenAiBackend's own chat_completion_stream never wired the guard at all, so today's live traffic (streaming or not) gets zero terminal coverage. - hooks.rs: make TerminalGuard pub, add ChatCompletionOutcome::StreamCompleted (streaming has no assembled response to report), and add TerminalGuardedChatStream -- a Stream wrapper that fires the terminal via TerminalGuard::fire_detached (a detached spawn, since Stream::poll_next can't .await) on stream end/error, with Drop as the mid-stream-drop fallback. Wire it into HookedOpenAiBackend::chat_completion_stream, which previously had no terminal coverage at all. - backend.rs: extract chat_completion_with_hooks/chat_completion_stream_with_hooks -- generic helpers mirroring HookedOpenAiBackend's admission/effective/terminal lifecycle, parameterized over a dispatch closure -- and wire StageOpenAiBackend's chat_completion_with_context and chat_completion_stream through them. Extracted (rather than inlined) so the lifecycle is unit-testable with a fake dispatch closure, independent of real generation, which needs a loaded model. - Add red-then-green coverage: streaming success/error/denied/dropped-mid-stream for both HookedOpenAiBackend and StageOpenAiBackend, plus non-streaming success/error/denied/cancelled for StageOpenAiBackend. All new tests failed before the wiring and pass after. cargo test: openai-frontend (204+7+2+1), skippy-server --lib (486, 3 ignored/model-gated), mesh-llm-host-runtime --lib (2562, 8 ignored) all green. cargo fmt clean.

HookedOpenAiBackendskips the post-dispatch clone when a policy returnsfalsefromobserves_dispatched_request(). This wrapper always clones the request twice per hook-enabled exchange: once fordispatched_requestand once for the guard. Those clones copy message content and inline media, so a policy that opted out still pays the cost the flag was added to remove.Gate both copies on the flag, and pass a default request when the policy does not observe it.

Pure move, no logic change — hooks.rs drops from 2070 to 855 lines, back under the 2000-line rule. All 27 hooks::tests::* still pass. CodeRabbit item B: the skippy backend wrapper's inlined hook lifecycle (`chat_completion_with_hooks` in skippy-server frontend/backend.rs) cloned the effective request unconditionally to hand to the post-dispatch hooks — the exact path `observes_dispatched_request()` was invented to protect. Gate the clone on the flag (default/empty request when false), mirroring `HookedOpenAiBackend::chat_completion_with_context` (openai-frontend hooks.rs). MeshAutoHookPolicy returns false, so this drops a per-completion full-request clone (message content + inline media) on the mesh auto-route path. Also adopt origin/main's post-merge struct changes in two touched test helpers so the crates type-check: skippy-server backend/tests.rs now builds StageOpenAiBackend with `iteration_scheduler` (main replaced decode_batcher / decode_frame_batcher), and host-runtime plugin/runtime.rs builds PluginRuntime with `_child: Option<Child>` + `connection_task`.

@ndizazzo Thanks for the thorough pass. Here's where each of the three blockers now stands, checklist-style, on the current head ( Blocker 1 — capsule IDs validated before terminal publication

Reviewed current head 456ce3a after resolving the backend conflict against current main. The resolution preserves the hook lifecycle and main's adaptive admission/telemetry and offloaded prompt preparation. Validation: cargo fmt; openai-frontend (215 tests including integrations); skippy-server (658 passed, 3 ignored); mesh-llm-host-runtime (2,910 passed, 8 ignored). GitHub reports the branch mergeable.

Reference implementation of the OpenAI exchange lifecycle contract in #1331 (the plugin-platform prerequisite surfaced by the Capsule Emit sidecar experiment, #1233 / #1332). Supersedes #1421 — reopened clean after addressing review.
What this adds
Two hooks on
OpenAiHookPolicy, wired intoHookedOpenAiBackend, so an out-of-process plugin can observe the exchange without becoming an HTTP reverse proxy — plus the rung-ladder response-leg verdict.Review addressed (from #1421)
