PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Request Changes
• Rationale: The main adoption path is the right shape and current-head CI is green, but the close-target explicitly says a foreign command on the defer port must be left alone with no spawn-into. The current full poll path can still spawn into that held port after reconcileSingletonPort() declines to adopt it.

Peer-Review Opening: I reviewed exact head 55d34e0789c7006b67334b48cdac35e139a3e6b8 against #14291, current PR state, and focused local validation. The expected-command adoption half is good; the remaining blocker is the foreign-holder branch of the same contract.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #14291 body and ACs, #14292 live state/checks, changed-file list, exact-head source for Orchestrator.mjs and ProcessSupervisorService.mjs, existing supervisor tests, and the current orchestrator poll ordering.
• Expected Solution Shape: The per-poll singleton-port reconcile should run before superviseTask() and make duplicateListenerPolicy: 'defer' safe for already-held ports. A matching expectedCommand holder should be adopted; a foreign holder must be left untouched and must not be spawned into; default reap semantics must stay unchanged.
• Patch Verdict: Partially matches. reconcileSingletonPort() now adopts a matching live holder and never kills under defer, which closes the primary stale-pidfile resume case. But when the only listener is foreign, adoptExistingSingletonListener() returns false, reconcileSingletonPort() returns 0, and the next superviseTask() call still runs the liveness-gated restart for state.running=false, which can call runTask('supervisor-restart') into the already-held port.
• Premise Coherence: Mixed. The rename/adoption design coheres with verify-before-assert and the thin-orchestrator direction, but the implementation currently overclaims #14291's no-spawn-into foreign-holder clause.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Resolves #14291
• Related Graph Nodes: ProcessSupervisorService, Orchestrator.poll, duplicateListenerPolicy: 'defer', Neural Link Bridge EADDRINUSE

🔬 Depth Floor

Challenge: The new foreign-command test only calls reconcileSingletonPort() and asserts no adopt/no kill. It stops before the production poll sequence where Orchestrator.poll() immediately calls superviseTask() afterward. A local full-path falsifier with a defer task, a foreign listener on singletonPort, state.running=false, and livenessProbe() => false still records a spawn:

{
  "spawned": [{"cmd":"node","args":["server.mjs"]}],
  "adopted": [],
  "killed": [],
  "state": {"running": true, "pid": 4321, "lastRunAt": 1000000},
  "outcomes": ["running"]
}

That is still the EADDRINUSE shape, just with a foreign holder instead of the expected Bridge holder.

Rhetorical-Drift Audit (per guide §7.4):

• PR description checked against implementation
• Anchor & Echo summaries checked against implementation
• Linked anchors checked against issue authority

Findings: Drift flagged. The code comment says a foreign command is left with "no spawn-into", but the next superviseTask() can still spawn because the running state remains false.

🧠 Graph Ingestion Notes

• [KB_GAP]: None.
• [TOOLING_GAP]: Memory Core prior-art sweep degraded during review: collection-count health probe timed out, so I relied on live issue/PR/source evidence.
• [RETROSPECTIVE]: The reapDuplicateListeners -> reconcileSingletonPort rename is correct; the missing bit is carrying the defer-port occupancy result through the same poll tick so superviseTask() cannot immediately undo the safety decision.

🎯 Close-Target Audit

• Close-targets identified: #14291
• #14291 confirmed not epic-labeled

Findings: Pass on target shape; implementation still misses one clause of the close-target fix text.

📑 Contract Completeness Audit

• Originating ticket contains a Contract Ledger matrix
• Implemented PR diff matches the Contract Ledger exactly

Findings: N/A for ledger enforcement on this bug-fix PR; the contract source is #14291's explicit AC/fix text, and the drift is behavioral rather than ledger-only.

🪜 Evidence Audit

• Findings: Evidence-AC mismatch flagged. CI and focused unit tests are green, but they do not exercise the full reconcileSingletonPort() -> superviseTask() poll path for a foreign holder.

N/A across listed dimensions: no MCP OpenAPI/tool-description surface and no skill/convention surface changed.

🧪 Test-Execution & Location Audit

• Branch checked out locally at exact head 55d34e0789c7006b67334b48cdac35e139a3e6b8 in tmp/review-14292-gpt-55d34.
• Canonical Location: changed tests stay under test/playwright/unit/ai/daemons/orchestrator/.
• Related tests executed.
• Additional full-path falsifier executed for the review challenge.

Findings: Related tests pass, but coverage misses the failing foreign-holder full poll edge.

Verification run:

node --check ai/daemons/orchestrator/services/ProcessSupervisorService.mjs
node --check ai/daemons/orchestrator/Orchestrator.mjs
git diff --check origin/dev...HEAD
npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/services/ProcessSupervisorService.spec.mjs test/playwright/unit/ai/daemons/orchestrator/Orchestrator.spec.mjs

Result: 98 passed (32.4s) plus syntax and diff checks clean.

📋 Required Actions

To proceed with merging, please address the following:

• Make a defer singleton-port task suppress the same-poll restart when the port is occupied by a foreign command. The expected-command holder should still be adopted; a foreign holder should still never be killed or adopted, but the supervisor must not immediately call runTask('supervisor-restart') into that held port after reconcileSingletonPort() returns.
• Add a regression that drives the production sequence, not only the helper in isolation: reconcileSingletonPort(taskName) followed by superviseTask(taskName, now, cooldown) with a defer task, state.running=false, a foreign listener on singletonPort, and a down/throwing liveness probe. Assert no adopt, no kill, and no spawn.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 78 - The service owns the policy and the orchestrator stays thin, but the policy result is not yet carried through the full poll tick.
• [CONTENT_COMPLETENESS]: 72 - JSDoc and tests document the intended cases, but the no-spawn-into foreign-holder clause is overstated.
• [EXECUTION_QUALITY]: 68 - Focused tests and CI are green; the missing full-path regression leaves the original port-collision class partially open.
• [PRODUCTIVITY]: 72 - This is close and the main adoption path is useful, but merging now would close #14291 with one documented edge still false.
• [IMPACT]: 82 - Prevents local Neural Link Bridge port-collision loops, a high-friction development/runtime failure.
• [COMPLEXITY]: 58 - Moderate supervisor state/poll-order bug, not a broad subsystem rewrite.
• [EFFORT_PROFILE]: Maintenance - Targeted behavior correction with focused regression coverage.

I’m requesting changes because the remaining failing case maps directly to the ticket's "foreign command on the port -> no spawn-into, no kill" requirement.
