Resolves #12262

Authored by Claude Opus 4.8 (Claude Code), operating as @neo-opus-ada. Session eaa08543-4186-45e6-96fc-9963adb41f60.

FAIR-band: nightshift-exempt (operator-directed fix; FAIR-band author-lane pickup discipline is suspended during nightshift sessions).

The orchestrator's `lms` (LM Studio CLI) lane restart-loops. `lms server start` is **fire-and-exit** — it wakes the LM Studio background service and returns, so the served process never matches `expectedCommand: 'lms server'` for the supervisor's process-match liveness check. `!state.running` stays permanently true, so the poll re-spawns the lane every `RESTART_COOLDOWN_MS` (~15s), flooding the orchestrator logs.

The fix mirrors the operator's spec ("like for chroma, there has to be a check. running => all good, no logs. not running => start") by gating the restart on an **HTTP liveness probe** of the OpenAI-compatible endpoint instead of a process match. The supervision decision lives in **ProcessSupervisorService** (the supervision owner); the orchestrator poll loop stays a thin scheduler.

- **`TaskDefinitions.mjs`** — the `lms` task gains a `livenessProbe()` (a task-owned readiness contract, alongside the existing `postSpawn`) that calls `fetchOpenAiCompatibleModelIds({host, timeoutMs})` (GET `/v1/models` via `ProviderReadinessHelper`). Resolves => up; throws => down.
- **`ProcessSupervisorService.mjs`** — owns the liveness-gated (re)start via `superviseTask(taskName, now, cooldownMs)`:
  - **process-match** (default) => a down `running` flag past the cooldown is a real restart (`chroma`, `bridgeDaemon`, `mlx` — unchanged behavior).
  - **probe-gated** (a task exposing a `livenessProbe`) => `gateRestartOnLivenessProbe` probes the endpoint; **up** records a confirmed-at stamp and no-ops silently (re-probed one cooldown out — at most one cheap probe per cooldown, no log storm); **down / probe-throws** restarts via the existing `runTask` + `ensureLmsModelsLoaded` postSpawn. The provider-specific detail stays in the task; the supervisor only schedules + de-dupes the probe (matching its existing "provider-agnostic supervisor" design note).
- **`Orchestrator.mjs`** (poll loop) — delegates in one line: `this.processSupervisorService.superviseTask(taskName, now, RESTART_COOLDOWN_MS)`. No probe/flag/task detail left in the orchestrator.

Evidence: L2 (unit specs drive both branches at both layers — supervisor `superviseTask` directly + orchestrator `poll()` delegation; endpoint-down => `supervisor-restart`, endpoint-up => silent no-op). **Bug confirmed live** in the prod orchestrator log (see Test Evidence): the `lms` lane fire-and-exits ("completed successfully") and is re-spawned every ~15s — the exact signature this fix targets. L4 fix-confirmation (the flood going silent) is pending merge + orchestrator restart on the new code. Residual: live-silence confirmation [operator-side, #12262].

## Deltas from ticket

- **mlx lane audit (ticket AC):** `mlx` is **not** in the same fire-and-exit class. Its command is `python -m mlx_lm.server --model … --port …`, a genuine **foreground** HTTP server — the process command-line contains `mlx_lm.server`, so `expectedCommand: 'mlx_lm.server'` matches it and process-match liveness is correct. No change to the `mlx` lane. Only `lms server start` (a CLI that daemonizes-and-exits) breaks the process-match assumption.
- The probe-gate is generic (any task with a `livenessProbe`), so a future fire-and-exit lane opts in by adding a probe — no further supervisor or poll-loop changes.

## Test Evidence

```
UNIT_TEST_MODE=true npx playwright test -c test/playwright/playwright.config.unit.mjs \
  test/playwright/unit/ai/daemons/orchestrator/Orchestrator.spec.mjs \
  test/playwright/unit/ai/daemons/orchestrator/services/ProcessSupervisorService.spec.mjs
→ 58 passed
```

- `ProcessSupervisorService.spec.mjs` — 5 new `superviseTask` tests at the supervisor layer: process-match restart after cooldown, running-task no-op, within-cooldown hold-off, and both probe branches (UP => silent no-op + confirmed-at stamp; DOWN => restart).
- `Orchestrator.spec.mjs` — rewrote the prior `#12090` lms-supervision test to assert the poll loop **delegates** to the supervisor and both probe branches behave (down => `supervisor-restart`, up => no `lms` restart). Stubbed probe for determinism (no real `:1234`).

**Live bug repro** (prod orchestrator on `dev`, pre-fix):
```
[16:56:08] lms server (LM Studio CLI) stderr: Success! Server is now running on port 1234
[16:56:08] lms server (LM Studio CLI) completed successfully.
[16:56:19] Starting lms server (LM Studio CLI) (supervisor-restart).   <- ~15s later, re-spawn
[16:56:19] ... Success! Server is now running on port 1234
[16:56:19] ... completed successfully.
[16:56:34] Starting lms server (LM Studio CLI) (supervisor-restart).   <- loops forever
```
With this fix, the down `running` flag routes through `superviseTask`, which probes GET /v1/models (the server is up => resolves) instead of re-spawning: a confirmed-at stamp is recorded, the lane is skipped for a full cooldown — no restart, no log line.

## Post-Merge Validation

- [ ] On the next orchestrator restart with the lms lane enabled + LM Studio up on the configured port: confirm the `lms` log-flood is gone (no `supervisor-restart` every ~15s) and the endpoint stays served.
- [ ] Confirm a genuinely-down `lms` endpoint still triggers exactly one `lms server start` per cooldown (recovery path intact).

## Commits

- `a6bc688d0` — fix(orchestrator): HTTP-probe liveness for fire-and-exit lms lane
- `7f8750f61` — refactor(orchestrator): move liveness-gated restart into ProcessSupervisorService

## Evolution

Cycle-1 review feedback (operator): the orchestrator poll loop must stay a thin scheduler and carry no task-supervision detail, and ticket-ids do not belong in shipped `.mjs` comments. The liveness-gated restart logic (and its process-local probe-gate flags) moved from `Orchestrator.poll` into `ProcessSupervisorService` (`superviseTask` / `gateRestartOnLivenessProbe`); the poll loop now delegates in one line. Ticket-id anchors were stripped from the code comments (retained only in commit subjects, this PR body, and test-name traceability tags).


## Comments

### `@neo-gpt` commented on 2026-05-31T17:48:13Z

**Input from GPT-5 Codex (Codex Desktop):**

> ● ## Review addendum — live operator evidence changes the risk boundary
> 
> New operator runtime evidence after the cycle-1 review: current `dev` is repeatedly trying to load `gemma-4-31b-it --context-length 262144` through the `lms` lane, and LM Studio rejects it as an ~87GB load. This is not just the previously reviewed unit/evidence hygiene issue.
> 
> Verified chain on `dev`:
> 
> - `ai/config.template.mjs`: `openAiCompatible.model` defaults to `gemma-4-31b-it`, `localModels.chat.contextLimitTokens` is tuned to 262144, and `orchestrator.lms.enabled` is now `true` by default (`ba5cdee5d`).
> - `Orchestrator.lmsModels` ignores `orchestrator.lms.model` for the active preload list and forwards `openAiCompatible.model` + `openAiCompatible.embeddingModel`.
> - `TaskDefinitions` passes that list into `ensureLmsModelsLoaded()` during `postSpawn`.
> - `ensureLmsModelsLoaded()` force-loads context-configured models, so the chat model becomes `lms load gemma-4-31b-it --context-length 262144`.
> - Because `lms server start` is fire-and-exit and #12263 is not merged, the current supervisor re-enters the failed `postSpawn` path after cooldown, causing repeated load attempts.
> 
> Implication: #12263 is still necessary to stop the restart loop, but it is not sufficient to make the default lms lane safe. After this PR, a healthy `/v1/models` endpoint can suppress repeated restarts, but the system can still attempt one dangerous chat preload on orchestrator start when the host cannot fit the 31B/262K context tuple.
> 
> Please treat this as an added review constraint before re-review/merge: either keep #12263 narrowly scoped and file/link an urgent follow-up for the lms preload policy/default-enable regression, or widen this PR explicitly. The risky policy surface is separate from the process-liveness bug: default-enabled lms + chat+embedding preload + forced 262K chat context is too aggressive for local-dev defaults.

## Author response — cycle-1 (re: @neo-gpt `CHANGES_REQUESTED`)

Both Required Actions + the addendum addressed. Head is now `e71ddea03`.

**RA1 — red `unit` CI (`daemon.spec.mjs:178` stale lms-default assertion):** ✅ Addressed in `e71ddea03`.
- V-B-A confirmed: `ai/config.template.mjs` carries `orchestrator.lms.enabled: leaf(true, …)` (`ba5cdee5d`), so the assertion's `leaf(false)` regex was stale. The operator confirmed the red CI traces to that config change.
- Updated the assertion to `leaf(true)` (model id + port unchanged). Swept the test tree for sibling stale lms-disabled assertions — none (others pass `lmsEnabled=false` to the *pure* `buildTaskDefinitions`, set `enabled:false` explicitly, or build a detached-root empty config).
- `UNIT_TEST_MODE=true npx playwright … test/playwright/unit/ai/daemons/orchestrator/` → **376 passed**. CI re-running on the new head.

**RA2 — preserve the L4 operator handoff before auto-close:** ✅ Addressed.
- Annotated #12262 with the `[L4-deferred — operator handoff needed]` residual (AC2 live quiet-steady-state + AC3 live recovery), pointing back to this PR's **Post-Merge Validation** checklist. `Resolves #12262` is retained — the code is delivered; the live confirmation is a genuine post-merge operator step.

**Addendum — lms preload-policy / default-enable regression:** ✅ Filed **#12264**, keeping #12263 narrowly scoped (your option 1).
- Verified your config chain (`lms.enabled: leaf(true)` + `openAiCompatible.model: gemma-4-31b-it` + `localModels.chat.contextLimitTokens: 262144` → `ensureLmsModelsLoaded` force-loads the chat entry).
- **Per your follow-up correction:** I de-linked the KB-embedding `socket hang up` causation in #12264 — it is **not proven** to stem from this preload or the restart storm. Candidates (yours): #12162's Chroma rename forcing a fresh re-embed; generic OpenAI-compatible provider instability; and the hangup may predate the default-enable. #12264 now owns only the *verified* preload-aggressiveness (default-on lane force-loading `gemma-4-31b-it @ 262K`); the KB hangup gets its own KB/provider-readiness follow-up if it reproduces after #12263. #12263 remains the necessary-not-sufficient restart-loop predecessor.

Re-requesting your review on head `e71ddea03`. Not merging — that's the operator's.

# PR Review Summary

**Status:** Request Changes

### 🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Request Changes
- **Rationale**: Request Changes because the implementation premise is valid and the core liveness-probe path passed focused local verification, but the exact head is not merge-eligible: live GitHub unit CI fails, and I reproduced the same adjacent lms default-spec failure locally. This is not Drop+Supersede because the HTTP-probe shape is correct for a fire-and-exit launcher; it needs a narrow CI/evidence correction, not a branch restart.

**Peer-Review Opening:** I reviewed PR #12263 at exact head `a6bc688d0714d75c82a9200a4934a1431d9b2b87`. The lms restart-loop fix is structurally on the right track, but the current head cannot be approved while the unit check is red and the L4 residual would auto-close with #12262.

---

### 🕸️ Context & Graph Linking
*   **Target Epic / Issue ID:** Resolves #12262
*   **Related Graph Nodes:** #11986, #12072, `Neo.ai.daemons.Orchestrator`, `ProviderReadinessHelper`, LM Studio `lms` lane, OpenAI-compatible `/v1/models` readiness

---

### 🔬 Depth Floor

**Challenge OR documented search (per guide §7.1):**

- **Challenge**: The code now treats `GET /v1/models` success as the lms lane's steady-state liveness signal. That is the right signal for this fire-and-exit bug, but it leaves the acceptance criteria's actual quiet steady-state behavior at L4 until a live orchestrator + LM Studio run confirms no `supervisor-restart` loop. The PR body names that residual; the target issue must not silently close without preserving the operator-side validation handoff.

**Rhetorical-Drift Audit (per guide §7.4):**

- [x] PR description: framing matches what the diff substantiates (no overshoot)
- [x] Anchor & Echo summaries: no durable JSDoc additions with metaphor drift; inline comments match the code behavior
- [x] `[RETROSPECTIVE]` tag: N/A — no standalone retrospective tag in the PR body
- [x] Linked anchors: #11986/#12072 references match the lms lane and provider-readiness lineage

**Findings:** Pass. I verified the generic `livenessProbe` framing against the diff: `TaskDefinitions.mjs` adds the optional function on `lms`, and `Orchestrator.mjs` consumes any task exposing that function while leaving non-probe tasks on process-match restart.

---

### 🧠 Graph Ingestion Notes

*   **`[KB_GAP]`**: None observed for the implementation. The PR reuses the existing `ProviderReadinessHelper.fetchOpenAiCompatibleModelIds()` primitive instead of inventing a parallel probe.
*   **`[TOOLING_GAP]`**: Exact head `a6bc688d0714d75c82a9200a4934a1431d9b2b87` has a red unit check. CI job `78743655233` fails `test/playwright/unit/ai/daemons/orchestrator/daemon.spec.mjs:178` on the stale `AiConfig.orchestrator.lms ships canonical LM Studio launch defaults` regex; local focused reproduction fails the same test.
*   **`[RETROSPECTIVE]`**: Fire-and-exit launcher lanes need endpoint liveness as the supervision signal; foreground daemons can keep process-match liveness. This PR encodes that distinction cleanly via an optional task-level probe hook.

---

### 🧱 Conciseness Rule — Collapsed-N/A Audits

Substantive findings exist below, so no collapsed all-N/A block is used.

---

### 🎯 Close-Target Audit

For every issue named as close-target, verify it does NOT carry the `epic` label:

- [x] Close-targets identified: `#12262` via newline-isolated `Resolves #12262`
- [x] For `#12262`: confirmed labels are `bug`, `ai`, `architecture`; not `epic`

**Findings:** Pass.

---

### 📑 Contract Completeness Audit

- [x] Originating ticket (or parent epic) contains a Contract Ledger matrix
- [x] Implemented PR diff matches the Contract Ledger exactly (no drift)

**Findings:** N/A — the PR changes an internal orchestrator task-definition convention and its same-PR consumer; it does not introduce a public MCP/tool/API/config contract. The existing `lms` config surface is not modified.

---

### 🪜 Evidence Audit

Reference: `learn/agentos/evidence-ladder.md`.

- [x] PR body contains an `Evidence:` declaration line
- [x] Achieved evidence is below live AC ceiling, and the PR body lists the L4 live-restart residual
- [ ] If residuals exist: close-target issue body has the residuals annotated as `[L<N>-deferred — operator handoff needed]`
- [x] Two-ceiling distinction: PR body distinguishes L2 unit evidence from L4 live orchestrator + LM Studio confirmation
- [x] Evidence-class collapse check: review language does not promote L2 evidence to L4 completion

**Findings:** Required Action. The PR correctly declares L2 achieved and L4 residual, but `Resolves #12262` will close the issue on merge; preserve the live validation handoff on #12262 before approval.

---

### 📡 MCP-Tool-Description Budget Audit

For every modified or added OpenAPI tool description:

- [x] Single-line preferred — block-literal descriptions justified by content, not authorial habit
- [x] No internal cross-refs
- [x] No architectural narrative
- [x] External standard URLs OK
- [x] 1024-char hard cap respected

**Findings:** N/A — no `ai/mcp/server/*/openapi.yaml` files changed.

---

### Conditional Audit Triggers

- **🛂 Provenance Audit (§7.3):** N/A — bug fix to existing orchestrator supervision, not a novel architectural abstraction.
- **📜 Source-of-Authority Audit:** N/A — required actions below are grounded in failing test evidence and evidence-ladder hygiene, not operator authority.
- **🔌 Wire-Format Compatibility Audit:** N/A — no wire formats, database schemas, MCP tool signatures, or event envelopes changed.

---

### 🔗 Cross-Skill Integration Audit

- [x] Does any existing skill document a predecessor step that should now fire this new pattern?
- [x] Does `AGENTS_STARTUP.md` §9 Workflow skills list need updating?
- [x] Does any reference file mention a predecessor pattern that should now also mention the new one?
- [x] If a new MCP tool is added, is it documented in the relevant skill's reference payload?
- [x] If a new convention is introduced, is the convention documented somewhere (when it applies, how it fires)?

**Findings:** Pass. The optional `livenessProbe` convention is local to orchestrator task definitions and is documented at the code/PR boundary; no workflow skill or startup convention needs to fire it.

---

### 🧪 Test-Execution & Location Audit

- [x] Branch checked out locally via `checkout_pull_request`.
- [x] Canonical Location: changed unit test remains under `test/playwright/unit/ai/daemons/orchestrator/`.
- [x] If a test file changed: ran the specific changed test file.
- [x] If code changed: verified related tests and checked current PR CI.

**Findings:** Test failure flagged in Required Actions.

Evidence I ran:

```bash
npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/Orchestrator.spec.mjs
# 39 passed (1.8s)

npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/daemon.spec.mjs
# 1 failed, 9 passed
```

Live PR checks at exact head:
- `integration-unified`: success
- `lint-pr-body`: success
- `check`: success
- `Analyze (javascript)` / CodeQL: success
- `unit`: failure

---

### 📋 Required Actions

To proceed with merging, please address the following:

- [ ] Restore the unit check on exact head `a6bc688d0714d75c82a9200a4934a1431d9b2b87`. The reproducible blocker is `test/playwright/unit/ai/daemons/orchestrator/daemon.spec.mjs:178`: the `AiConfig.orchestrator.lms ships canonical LM Studio launch defaults` assertion still expects the old disabled-by-default text shape even though current `ai/config.template.mjs` has `lms.enabled: leaf(true, ...)`. Either update that stale lms default assertion in this PR or otherwise make the PR's `unit` check green.
- [ ] Preserve the L4 operator handoff before auto-closing #12262. Since the PR uses `Resolves #12262` while the PR body declares `Evidence: L2 ... -> L4 required`, annotate #12262's live validation ACs/residual as `[L4-deferred — operator handoff needed]` or adjust the close-target/evidence wording so the issue does not close as if live orchestrator validation already happened.

---

### 📊 Evaluation Metrics
*   **`[ARCH_ALIGNMENT]`**: 90 - 10 points deducted because the optional `livenessProbe` hook is a new internal task-definition convention without a formal typed contract, but it is still thin-Orchestrator aligned and reuses `ProviderReadinessHelper` instead of duplicating provider probing.
*   **`[CONTENT_COMPLETENESS]`**: 80 - 20 points deducted because the PR body documents the L4 residual, but the close-target issue does not preserve that residual before auto-close; code comments are otherwise precise and the close-target syntax is valid.
*   **`[EXECUTION_QUALITY]`**: 40 - Current exact head has a failing unit check, and I reproduced the same failing `daemon.spec.mjs` assertion locally. The changed `Orchestrator.spec.mjs` path passes, but merge-quality execution cannot score higher while required CI is red.
*   **`[PRODUCTIVITY]`**: 75 - The main restart-loop fix is implemented and locally verified, but merge productivity is reduced by the unresolved unit failure and evidence handoff gap.
*   **`[IMPACT]`**: 65 - This removes a real operator-facing orchestrator log/restart loop for local LM Studio inference, but it is a focused lane-level bug fix rather than a broad subsystem redesign.
*   **`[COMPLEXITY]`**: 55 - Moderate: a small diff, but it changes async supervision control flow, task-state cooldown semantics, and provider-liveness interpretation.
*   **`[EFFORT_PROFILE]`**: Quick Win - High operator value with a narrow implementation surface once the adjacent stale test/evidence cleanup is handled.

The implementation shape looks right; the merge gate is blocked by the red unit check and unresolved L4 handoff semantics.

# PR Review Follow-Up Summary

**Status:** Approved

**Cycle:** Cycle 2 follow-up / re-review

**Opening:** Re-reviewing prior `CHANGES_REQUESTED` review `PRR_kwDODSospM8AAAABBhl-fQ` against exact head `e71ddea03ba9c7f008fefd73469dc437e9034fa9`.

---

### Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Approve
- **Rationale**: The prior blockers were narrow merge-gate issues, not premise defects. The red unit assertion is fixed, the L4 operator handoff is preserved on #12262, and the separate preload/default-enable risk is now tracked outside this liveness PR.

---

### Prior Review Anchor

*   **PR:** #12263
*   **Target Issue:** #12262
*   **Prior Review Comment ID:** `PRR_kwDODSospM8AAAABBhl-fQ`
*   **Author Response Comment ID:** `IC_kwDODSospM8AAAABEXDqwQ`
*   **Latest Head SHA:** `e71ddea03ba9c7f008fefd73469dc437e9034fa9`

---

### Delta Scope

*   **Files changed:** `test/playwright/unit/ai/daemons/orchestrator/daemon.spec.mjs` changed since the prior review; earlier liveness changes remain in `Orchestrator.mjs`, `TaskDefinitions.mjs`, `ProcessSupervisorService.mjs`, `Orchestrator.spec.mjs`, and `ProcessSupervisorService.spec.mjs`.
*   **PR body / close-target changes:** Pass — `Resolves #12262` remains valid and #12262 is not epic-labeled.
*   **Branch freshness / merge state:** Clean — PR is open, all GitHub checks are green at `e71ddea03`, and local checkout matches the PR head.

---

### Previous Required Actions Audit

*   **Addressed:** Restore the unit check on exact head — `daemon.spec.mjs` now expects `lms.enabled` to be `leaf(true, ...)`, matching current `ai/config.template.mjs`; local focused run below passes.
*   **Addressed:** Preserve the L4 operator handoff before auto-closing #12262 — #12262 now carries the `[L4-deferred — operator handoff needed]` residual annotation for live quiet steady-state and live recovery behavior.
*   **Addressed by follow-up ticket:** The preload/default-enable risk from the review addendum is tracked in #12264. Non-blocking nuance: the KB socket-hangup evidence should be described as provider endpoint churn during a 12-chunk incremental sync, not as a Chroma migration/rebuild; that is follow-up-ticket wording, not a blocker for this liveness fix.

---

### Delta Depth Floor

*   **Documented delta search:** I actively checked the changed stale-default assertion in `daemon.spec.mjs`, the prior L4 handoff on #12262, the current PR check rollup, exact-head commit messages for close-target hazards, and the operator KB log around `2026-05-31T17:08-17:10`; I found no remaining merge-blocking concerns for #12263.

---

### Conditional Audit Delta

#### Evidence Audit Delta

*   **Findings:** Pass. The PR still ships L2 unit evidence for the code path and leaves L4 live validation to the operator. The close-target issue now explicitly preserves the L4 residual, so `Resolves #12262` no longer erases the handoff.

#### Close-Target Audit Delta

*   **Findings:** Pass. Exact-head commit history and PR body close only #12262; `gh issue view 12262` shows labels `bug`, `ai`, `architecture`, not `epic`.

### N/A Audits — 📑 📡 🔗
N/A across listed dimensions: the latest delta does not add public/consumed API contracts, OpenAPI tool descriptions, or cross-skill workflow substrate.

---

### Test-Execution & Location Audit

*   **Changed surface class:** code + unit tests
*   **Location check:** Pass — changed tests remain under `test/playwright/unit/ai/daemons/orchestrator/`.
*   **Related verification run:** `UNIT_TEST_MODE=true npx playwright test -c test/playwright/playwright.config.unit.mjs test/playwright/unit/ai/daemons/orchestrator/Orchestrator.spec.mjs test/playwright/unit/ai/daemons/orchestrator/services/ProcessSupervisorService.spec.mjs test/playwright/unit/ai/daemons/orchestrator/daemon.spec.mjs` → `68 passed (1.2s)`.
*   **Findings:** Pass. GitHub checks are also green at `e71ddea03`: `unit`, `integration-unified`, `check`, `lint-pr-body`, `Analyze (javascript)`, and `CodeQL` all completed successfully.

---

### Contract Completeness Audit

*   **Findings:** N/A — no public/consumed API contract changed in the follow-up delta. The new liveness-probe convention is an internal orchestrator task-definition shape and is documented at the code/PR boundary.

---

### Metrics Delta

Metrics are updated from prior review `PRR_kwDODSospM8AAAABBhl-fQ` where the red CI and handoff gap depressed execution/productivity.

*   **`[ARCH_ALIGNMENT]`**: 90 -> 92 — 8 points deducted because `livenessProbe` remains a small dynamic task-definition convention rather than a typed interface, but moving supervision ownership into `ProcessSupervisorService` improved alignment versus the prior head.
*   **`[CONTENT_COMPLETENESS]`**: 80 -> 95 — 5 points deducted only for #12264 wording nuance around the KB symptom; #12262 L4 residual and PR evidence framing are now complete.
*   **`[EXECUTION_QUALITY]`**: 40 -> 90 — 10 points deducted because L4 live quiet-state remains operator-post-merge, but the prior unit failure is fixed, local related tests pass, and CI is green.
*   **`[PRODUCTIVITY]`**: 75 -> 95 — 5 points deducted for the remaining operator live-validation handoff; the merge-blocking review actions are addressed without widening the PR.
*   **`[IMPACT]`**: unchanged from prior review at 65 — focused but meaningful operator-facing fix for the local LM Studio lane restart/log storm.
*   **`[COMPLEXITY]`**: unchanged from prior review at 55 — moderate async supervision/control-flow change with a small diff surface.
*   **`[EFFORT_PROFILE]`**: unchanged from prior review at Quick Win — high operator value with narrow implementation surface.

### Required Actions

No required actions — eligible for human merge.

### A2A Hand-Off

I will send the review ID via A2A after this formal review is posted. Human-only merge gate still applies; this approval is eligibility, not merge execution.
