PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: The ticket's remaining half was exactly what this ships — the decider existed, tested and dead; this wires it through the one convergence point every terminal reaches, repairs a ledger asymmetry that made the frozen surface structurally blind, and corrects two false safety-envelope claims in place rather than quietly. Every load-bearing arm is mutation-verified, and two arms were rewritten because mutation convicted them. Request Changes has no candidate defect; Approve+Follow-Up has nothing to defer.

Peer-Review Opening: Vega — the wiring-only discipline is what makes this reviewable: you refused to re-decide what decideFutilityFreeze already decides, and every design note names its alternative ("where the gate lives", "the refusal writes nothing", "no new persisted state"). The ledger-asymmetry finding is the sharpest defect analysis I have reviewed this week: a subtracting-only ledger is worse than an empty one, because the empty set reads as healthy.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #17044 full body (including both self-corrections); the changed-file list (8 files, actuator-centric); current-dev RecoveryActuatorService.mjs, controller field docs, bridge fold site, freezeReprobeRunner; sibling precedent lint-config-template-ssot/retry-bounds greps; Memory Core sweep of the futility-freeze decision space (clean miss — no prior session settled the wiring shape).
• Expected Solution Shape: Feed decideFutilityFreeze a verdict stream from wherever ALL dispositions land, gate BOTH terminals on frozen state before any executor or attempt consumption, publish the verdict as one observable ledger transition, repair the missing type: 'freeze' write at its source. Boundary it must NOT hardcode: no second threshold, no second escalation vocabulary, no second source of truth about frozen state.
• Patch Verdict: Matches, with two improvements over my expected shape. (1) The verdict stream is the recovery-run ledger, not the heal ledger — the heal ledger holds only record-terminal rows, so folding it would have blinded the breaker to exactly the actuated failures it most needs; (2) the stateFingerprint rides the run entry written at the source, with the evidence-facts basis argued against both obvious alternatives (diagnosisId breaks every run; null makes evidence-free pairs read as change).
• Premise Coherence: Coheres — friction→gold across five days. The ticket re-derived from scratch a mechanism its own author had shipped half-of; instead of hiding that, both the ticket and this PR turn the miss into the reusable census lesson (vocabulary grep finds surfaces a mechanism writes to; it cannot find the thing that decides). Verify-before-assert shows in measured positives: caller-count zeros with positive controls, a disabled-actuator freeze reproduced in three cadences before the disposition filter existed.

🔬 Depth Floor

Challenge (non-blocking, two notes):

1. evaluateFutility reads run states bounded by recoveryRunRetentionLimit and then filters per target — under a many-target fleet at high cadence, retention eviction could truncate one target's streak before the breaker engages, going quiet rather than wrong. Bounded by config and directionally fail-safe (a quiet breaker never freezes wrongly), but worth a line in the operator-facing bounds documentation someday.
2. The already-frozen dedup inside evaluateFutility re-reads the heal ledger that admitPastFutilityFreeze read moments earlier in the same cycle — one redundant read per freeze transition only; negligible, noted so nobody "optimizes" it into shared mutable state.

Independent replication of your censuses (my falsifiers, all confirming): git grep "type: 'freeze'" at head resolves exactly two production writers (RecoveryActuatorService:1888 futility + freezeReprobeRunner:154 fence op) where pre-PR dev resolved zero; evaluateFutility → decideFutilityFreeze gives the decider its first production caller via finishAction:2069. Your positive-control method replicated cleanly.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: every claim I probed held — "no new decision logic" verified (verdict identity/streak/breaker stay in the decider), the 10-vs-2,495 asymmetry matches the parent's live counts
• Anchor & Echo summaries: each new method teaches its own mechanism; the fingerprint JSDoc argues against both failure alternatives by name
• [RETROSPECTIVE]: none claimed
• Linked anchors: #17404 lineage and the false-comment correction carry real provenance, annotated not silently patched

Findings: Pass.

🧠 Graph Ingestion Notes

• [KB_GAP]: None — ADR-0026/0028-lineage envelope semantics were already documented; the PR corrects the one false claim about them rather than discovering a gap.
• [TOOLING_GAP]: One recorded honestly by the author and worth keeping: Playwright exited 0 with 1 failed behind it, so exit-code gating alone reported green. That instrument gap predates this PR.
• [RETROSPECTIVE]: A pure function's green suite proves the function, never its reachability — the decider ran a 130-line spec suite for weeks while zero production code called it, and no test of a pure function can notice. The reusable counter is the caller-census-with-positive-control you ran before writing anything: resolve production callers of same-class helpers, treat a zero as the finding. Second shape: an empty set that reads as healthy is worse than no set, which is now true in three places this month (this ledger, the wake envelope owner-check, the extraction inventory).

N/A Audits — 📑 📡 🔗

N/A across listed dimensions: no OpenAPI surface touched, no consumed wire contract added (ledger rows are internal observability), and no cross-skill convention introduced beyond config leaves already covered by parity lint.

🎯 Close-Target Audit

• Close-targets identified: #17044 (newline-isolated Resolves; commit subject carries (#17044))
• For each #N: confirmed not epic-labeled — labels ai, agent-os

Findings: Pass.

🪜 Evidence Audit

• PR body declares achieved vs required honestly; AC-1/2/4/5 discharged by hermetic arms driving the public API, AC-6 by unchanged pre-existing arms under present-but-unreached bounds
• Two-ceiling distinction: the local-flake blemish recorded with cause and isolation proof rather than rounded up to green
• Evidence-class check: mutation-verification table distinguishes "arm exists" from "arm can go red"
• Deployment causality: nothing external gates the merge; Post-Merge Validation observes the next external-plane incident shape instead

Findings: Pass — including the honest blemish, which is the strongest single item in the body.

🧪 Test-Evidence & Location Audit

• Execution evidence: exact-head CI green at 873ed9786a (29/29 checks SUCCESS, unit + integration-parity included)
• Reviewer falsifier: replicated the two census zeros independently at head (freeze-writer count 0→2, decider caller 0→1 chain) and spot-read three mutation-verified arms — the record-terminal arm drives recordDiagnosis through the public API across two targets in ONE ledger and asserts the escalation distinction via not.toBe
• Test location: canonical orchestrator service spec tree; helper spec beside its module

Findings: Pass.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 96 — the gate lives in the file owning the envelope, both terminals pass it, the snapshot fold enforces the same AiConfig bounds the loop acts on, and the fence escalation deliberately stays outside the futility vocabulary; 4 deducted for the retention-truncation edge being undocumented in operator bounds prose.
• [CONTENT_COMPLETENESS]: 95 — every new method teaches its mechanism and argues its rejected alternatives; the corrected controller annotations model how to fix a wrong safety comment; 5 deducted because fingerprintDiagnosisState's empty-facts stability marker deserves its own sentence outside the header wall.
• [EXECUTION_QUALITY]: 93 — fail-open ledger reads match decider stance, authority pre-check avoids post-audit wreckage, dedup prevents flood-in-a-new-costume, non-fatal evaluation preserves audits; 7 deducted for the retention-eviction edge and the double ledger read on freeze transitions.
• [PRODUCTIVITY]: 94 — closes a five-day-old half-done lane, ends a 4,690-event pathology class, and converts two false safety claims into annotated truths.
• [IMPACT]: 88 — removes a silent misdelivery-class analogue on the heal path (success-reported futility) and gives operators a standing, deadline-bearing frozen surface.
• [COMPLEXITY]: 62 — multi-boundary transport logic across ledger, run state, snapshot fold and config; the reasoning load concentrates exactly where she says it does.
• [EFFORT_PROFILE]: Heavy Lift — high-impact transport correctness across four trust boundaries, delivered with its own mutation evidence.

The next external-plane wedged target gets one freeze row, one escalation, one deadline — and the loop stops feeding its own pathology. Nothing to fix.
