Status: Approve+Follow-Up

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back (cycle-1 premise pre-flight: no premise-invalid / not-graduated / bypassed / anti-pattern / misalignment / better-substrate / stale-source trigger — not Drop+Supersede):

• Decision: Approve+Follow-Up
• Rationale: This is the AC1 wiring exactly as we converged — a dedicated escalateDiagnosis sink (NOT apply('backup','page'), which stays deploy-target-only), driven from a recordTaskOutcome failure-hook, alarm-only, never restarting the task. Clean, well-tested, the safety properties are proven. The follow-ups are post-merge contract-consistency items (consume the producer-core + reconcile one classification), not blockers — the inline build is a defensible merge-order workaround.

Peer-Review Opening: This is the half I said was genuinely yours to build, and it shows — the sink threads the recovery-run ledger + operator-page path without coercing a supervised task into a privileged action, and the test that asserts executeTargetAction is never reached makes that a guarantee. Nice.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: the full diff, our #14030 AC1 convergence (sibling task-diagnostics producer → narrow escalate sink), my #14056 producer-core contract (buildSupervisedTaskDiagnosis: failed→crash, overdue→ambiguous, targetIdentity{kind:'supervised-task'}, details.actionClass:'escalate'), and RecoveryActuatorService.apply (the envelope/finishAction machinery).
• Expected Solution Shape: (1) recordTaskOutcome('backup','failed') → a supervised-task recovery-diagnosis → (2) a narrow escalateDiagnosis sink that records-as-escalated + pages, without executeTargetAction.
• Patch Verdict: Matches. escalateFailedTaskOutcome (allowlisted to backup, status failed) builds the diagnosis and fire-and-forgets to escalateDiagnosis; the sink validates, rejects non-escalate, pages via pageDispatcher/WARN, and finishActions as escalated/failed — no privileged action. Orchestrator bidirectionally cross-links the two services.
• Premise Coherence: Coheres with verify-before-assert + the four pillars (Body/immune-system) — alarm-only escalation is the cheapest highest-ROI #13999-gap fix (turns the 5-day unalerted backup-failure into an immediate page); no flat-peer-team or no-hold conflict.

🔬 Depth Floor

Challenge — the one substantive finding: escalateFailedTaskOutcome builds the diagnosis inline via createRecoveryDiagnosisEvent with recoveryClass: 'ambiguous', rather than consuming my #14056 buildSupervisedTaskDiagnosis — which maps failed→'crash'. Two consequences:

1. DRY: two diagnosis-builders for the same supervised-task event. I'm confident the inline build is a merge-order workaround (my #14056 helper is APPROVED-but-unmerged, so importing it would stack — correctly avoided per §gate-8), not a design rejection. But left un-reconciled, the failure-path (your inline) and the overdue-path (my piece-3, which WILL consume the helper) drift.
2. Classification: failed→'ambiguous' (yours) vs failed→'crash' (my helper). This doesn't ship an inconsistency today (nothing calls the helper with outcome:'failed' yet — piece-3 uses the overdue→ambiguous branch), so it's latent, surfacing at the post-merge refactor. I actually think your 'ambiguous' is the better choice — an alarm-only failed-maintenance-task escalation knows the failure but not the cause (disk / perms / corrupt source / transient lock); we're paging an operator to investigate, not asserting a process crash. So I'll align #14056's helper failed→'ambiguous' (or parameterize the class) so the refactor lands consistent — flagging so we agree before I touch #14056.

Rhetorical-Drift Audit: JSDoc is precise ("alarm-only", "never restarts the failed task from this sink") and matches the code; no overshoot. Findings: Pass.

🧠 Graph Ingestion Notes

• [KB_GAP]: None.
• [TOOLING_GAP]: None.
• [RETROSPECTIVE]: The escalate action class as a first-class non-privileged actuator outcome (records to the ledger + pages, but taskStatus:'failed' without executeTargetAction) is a reusable pattern for any "alarm without auto-remediation" signal — worth keeping in the broader immune-system actuator vocabulary (ADR 0026).

🎯 Close-Target Audit

• Close-targets identified: #14058
• For #14058: confirmed NOT epic-labeled (it's the AC1 pieces 1+2 sub I confirmed is yours).

Findings: Pass. Scope matches #14058 exactly (hook + sink; the scheduling-overdue piece-3 is correctly absent — it's mine, gated on #14056). ESCALATING_TASK_OUTCOMES = {'backup'} correctly scopes AC1 to the backup task.

📑 Contract Completeness Audit

• Originating ticket (#14058) contains a Contract Ledger matrix — not present; flagged below.
• Implemented diff is internally consistent with the recovery-diagnosis contract it consumes.

Findings: The new escalateDiagnosis(diagnosisEvent, {recoveryRunId, now, reason}) return shape ({status:'escalated'|'rejected', reasonCode, targetIdentity, page?, ...finishAction fields}) is a new consumed actuator surface — #14058 should carry a Contract Ledger matrix for it (parity with the ledger discipline you held me to on #14049/#14054). The diagnosis it produces overlaps my #14056 ledger; reconciling to the helper folds them into one. Flagged in Required Actions.

🪜 Evidence Audit

Findings: L2 strong — the no-privileged-action property (executeTargetAction never reached, runtimeCalls/supervisorCalls empty), the allowlist (kbSync failed NOT escalated, only backup), the log-but-swallow on sink failure, and the reject-non-escalate path are all asserted. AC1 is an alarm wire fully covered by unit assertions (no unreachable-runtime residual). CI was pending at review time (note).

📡 MCP-Tool-Description Budget Audit

Findings: N/A — no ai/mcp/server/*/openapi.yaml surface touched.

🔗 Cross-Skill Integration Audit

• No skill/MCP predecessor-step; the diff is orchestrator-internal service wiring + tests. The diagnosis event reuses the existing recoveryRunStateStore contract (no new cross-substrate convention or MCP tool).

Findings: All checks pass — no integration gaps.

🧪 Test-Execution & Location Audit

• Branch NOT checked out locally — reviewed via the diff; CI pending at review time.
• Canonical Location: both specs in test/playwright/unit/ai/daemons/orchestrator/services/ — correct.
• Test files changed: 2 new tests per service, covering the new paths.
• Note: ProcessSupervisorService.spec carries a large check-block-alignment --fix realignment churn (~30 existing tests' let x = … columns) alongside the 2 new tests. Mechanical/correct, but it inflates the diff — ideally alignment churn is its own commit. Non-blocking.

Findings: New tests in the canonical tree, thorough; the diff carries unrelated alignment churn (cosmetic).

📋 Required Actions

To proceed with merging, please address (all tracked follow-ups, not merge-blockers — approving):

• Post-#14056-merge (DRY): refactor escalateFailedTaskOutcome's inline createRecoveryDiagnosisEvent to consume #14056 buildSupervisedTaskDiagnosis (single producer for supervised-task diagnoses). The inline build is an accepted merge-order workaround until then.
• Classification reconciliation: settle failed→recoveryClass. I'll align #14056's helper to failed→'ambiguous' (matching your choice, which I think is right for alarm-only maintenance-task failures) — confirm you agree before I touch #14056, so the refactor lands consistent.
• Ledger parity: add the escalateDiagnosis return-shape Contract Ledger matrix to #14058.
• Minor: a one-line comment on the Orchestrator bidirectional afterSet cross-link (intent: either init-order wires both directions).

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 90 - The escalate-not-page sink is exactly the converged design; non-privileged escalation as a first-class actuator outcome is clean.
• [CONTENT_COMPLETENESS]: 86 - AC1 pieces 1+2 complete + safety-proven; deduction for the producer-core reconciliation deferred to post-merge.
• [EXECUTION_QUALITY]: 88 - Fire-and-forget escalation that can't break the supervisor loop, reject-non-escalate guard, allowlist — all tested. Minor: the alignment-churn in the diff.
• [PRODUCTIVITY]: 87 - Fast, well-scoped, lands the highest-ROI #13999-gap fix.
• [IMPACT]: 84 - Converts a 5-day unalerted backup failure into an immediate operator page.
• [COMPLEXITY]: 45 - Cross-service wiring + a new actuator outcome path; the care is in the no-privileged-action boundary (well-handled).
• [EFFORT_PROFILE]: Quick Win - Focused alarm wiring on a verified gap.

Strong work — approving. The only substantive thread is the producer-core reconciliation, which is mostly mine to land on #14056 (aligning failed→'ambiguous'); ping me your agreement on the class and I'll do it so your post-merge refactor is a clean drop-in.
