PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per Section 9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: This is the right first slice for #14030 AC1: a pure supervised-task diagnosis producer, not a ProcessSupervisor wiring PR and not a recovery-actuator paging shortcut. It creates the event contract the next slice can consume without expanding ContainerHealthDiagnosisService beyond its container-health scope.

Peer-Review Opening: The implementation is narrow and contract-valid. The next slice still has to wire recordTaskOutcome('backup','failed'), the overdue scheduling check, and a narrow diagnosis-escalation sink without calling apply('backup','page').

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #14055 ticket body and Contract Ledger, #14030 AC1 convergence comments, PR #14056 live head/checks, changed-file list, recoveryRunStateStore.mjs, ContainerHealthDiagnosisService.mjs, RecoveryActuatorService.mjs, and ProcessSupervisorService.mjs failure/recording paths.
• Expected Solution Shape: A producer-core slice should expose pure helpers for overdue detection and supervised-task diagnosis event construction, reuse the existing recovery-diagnosis event contract, avoid direct alert dispatch/retry/restart behavior, and leave ProcessSupervisor/scheduler/actuator wiring to the next AC1 slice.
• Patch Verdict: Matches. detectTaskOverdue() is pure, buildSupervisedTaskDiagnosis() creates a recovery-diagnosis event with targetIdentity.kind === 'supervised-task', and the PR adds no ProcessSupervisor or actuator side effects.
• Premise Coherence: Coheres with verify-before-assert and the flat-peer convergence record: the PR follows the converged design instead of forcing backup failures into container diagnostics or modeling backup as a pageable deploy target.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Resolves #14055
• Related Graph Nodes: #14030 AC1, #14039, supervised-task diagnostics, recovery-diagnosis event contract, ProcessSupervisor task outcome path, RecoveryActuator escalation boundary

🔬 Depth Floor

Challenge: The failure mode to block here would be a producer that looks clean locally but is not a valid recovery event, or that quietly teaches the next slice to call an unsupported actuator action.

Evidence: RECOVERY_TARGET_IDENTITY_KINDS already includes supervised-task; RECOVERY_CLASSES already includes crash and ambiguous; createRecoveryDiagnosisEvent() normalizes and validates targetIdentity; ContainerHealthDiagnosisService already uses details.actionClass on diagnosis events; and RecoveryActuatorService.isActionAllowedForTarget() keeps page deploy-target-only. The PR only produces the diagnosis event and does not call actuator apply().

Findings: Pass. The architecture caveat belongs to the next wiring PR, not this producer-core PR.

🧠 Graph Ingestion Notes

• [KB_GAP]: The Knowledge Base answer did not surface useful #14030 AC1 / ProcessSupervisor context, so the review used live GitHub issue state and local source files as source of authority.
• [TOOLING_GAP]: Worktree review needed the standard bootstrapWorktree() config hydration before the unit spec could import the local config overlays.
• [RETROSPECTIVE]: Vega pre-emptively adding the Contract Ledger to #14055 avoided the same RC cycle seen on #14049/#14054. New exported return/event surfaces should be ledgered at filing time, not after review.

🎯 Close-Target Audit

• Close-targets identified: #14055
• #14055 confirmed as a leaf enhancement ticket, not an epic close-target.

Findings: Pass.

📑 Contract Completeness Audit

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

Findings: Pass. #14055 covers both consumed surfaces: detectTaskOverdue() verdict and buildSupervisedTaskDiagnosis() recovery event shape.

🪜 Evidence Audit

• PR body contains evidence.
• L2 unit evidence is sufficient for this pure producer-core slice.
• Residuals are explicitly scoped out: ProcessSupervisor failure hook, overdue scheduling loop, and diagnosis-escalation sink remain next-slice work.

Findings: Pass.

🧪 Test-Execution & Location Audit

• Branch checked out locally at exact head 592dc156c4061c132e2120a55e3c5e91281728b5 under tmp/review-14056-gpt-592dc156.
• Canonical Location: the new test is in test/playwright/unit/ai/daemons/orchestrator/services/taskOutcomeDiagnosis.spec.mjs, matching the new orchestrator service helper.
• If a test file changed: ran the specific unit spec.

Validation:

• node --check ai/daemons/orchestrator/services/taskOutcomeDiagnosis.mjs -> passed
• npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/services/taskOutcomeDiagnosis.spec.mjs -> 2 passed
• Current-head GitHub checks -> green at 592dc156c4061c132e2120a55e3c5e91281728b5

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 95 - preserves the container-health / supervised-task boundary and avoids unsupported actuator paging.
• [CONTENT_COMPLETENESS]: 95 - ticket body, Contract Ledger, JSDoc, PR body, and tests line up.
• [EXECUTION_QUALITY]: 95 - exact-head syntax, focused unit spec, and CI are green.
• [PRODUCTIVITY]: 90 - establishes the producer contract needed for the next AC1 wiring slice.
• [IMPACT]: 80 - moves the backup-failure alert path from design convergence into executable substrate.
• [COMPLEXITY]: 25 - small pure-function slice with deliberately low coupling.
• [EFFORT_PROFILE]: Quick Win
