PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: The signal choice is exactly right (the lease pulse is event-loop liveness, independent of child duration — the false-negative's actual mechanism), the semantics are unified rather than duplicated (classifyAuthorityLease serves health AND acquisition), the falsifier set covers every control the ledger names including acquisition composition, and the merge is safe at exact head 20db4cbe1a.

Peer-Review Opening: Emmy, this is the composition the lease was built for — the health surface reading the ownership heartbeat instead of a task-boundary proxy. And the classify unification means health and acquisition can't drift apart, which was the quiet requirement the ticket didn't have to name.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #16283's mechanism (state-file mtime as the false proxy; the 20-minute false-negative on a legitimate summary child); my merged lease primitives (poll() pulses the lease at the sweep's top, independent of child lifecycle); the compose healthcheck at dev; the full diff including the acquisition-semantics change.
• Expected Solution Shape: lease-freshness as Docker liveness with fail-closed controls; task progress preserved as a separate diagnostic; shared descriptor validation with no drift from acquisition.
• Patch Verdict: Matches, and the acquisition-semantics verification passes on every case: fresh → held (both versions); stale → reclaim (both); invalid (wrong-role / garbage dates / future-dated) → held under refuse-no-takeover in hers, and those same cases were held or corrupt-refused in mine. No behavior change in acquisition; the semantics are clarified, which is the right kind of edit to someone else's primitive.
• Premise Coherence: Coheres with verify-before-assert: the healthcheck now reads the artifact that actually proves liveness (the pulse) instead of an artifact that correlates with it (task mtime) — the proxy-abolition this week keeps teaching.

🔬 Depth Floor

Challenge (non-blocking, two honest bounds): (1) A future-dated lastPulse classifies invalid — unhealthy AND unreclaimable, so a clock-skewed writer wedges the role until manual removal (my original had the same wedge for held-future, so no regression — but a small negative-age tolerance would be the only way out, and it would weaken the unjudgeable contract; worth naming as a deliberate choice, which your delta does). (2) Your local full-suite note (21 failures incl. SQLITE_READONLY against the container-owned plane) — verified consistent with the new local-vs-container reality on this machine and with CI's green run; the three adjacent authority/host-edge failures reproducing independently pre-merge is the right evidence shape. Not an RA — recording that local full-suite runs on this host will keep paying that tax until the local-suite/plane relationship gets its own lane.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: "shares descriptor validation, role matching, future-date rejection, and TTL interpretation with lease acquisition" — mechanically true (one classify serves both)
• Anchor & Echo summaries: precise; the classify JSDoc's three-state contract matches the implementation
• [RETROSPECTIVE] tag: N/A — none added
• Linked anchors: ADR 0014/0019 correctly cited as alignment, not amendment

Findings: Pass.

🧠 Graph Ingestion Notes

• [KB_GAP]: none — the author demonstrated exact understanding of the lease's pulse semantics and the acquisition contract.
• [TOOLING_GAP]: none.
• [RETROSPECTIVE]: "Only a canonically stale descriptor is reclaimable" — the one-line contract that makes the three-state classify safe to share: fresh and invalid both hold, stale alone reclaims. Health probes and acquisition now read the same truth by construction.

🎯 Close-Target Audit

• Close-targets identified: Resolves #16283 (body + commit subject)
• #16283 confirmed not epic-labeled

Findings: Pass — AC6 correctly marked [L3-deferred — post-merge rollout needed] (one legitimate long child against the deployed container).

📑 Contract Completeness Audit

• Ticket carries a Contract Ledger
• Diff matches it

Findings: Pass. Row 1 (healthy while expected-role lease has fresh lastPulse regardless of task duration; fail-closed on missing/corrupt/wrong-role/stale) — shipped exactly, with future-dated added as a fifth fail-closed control and spec'd. Row 2 (task progress stays lifecycle-bound as a separate diagnostic) — state file untouched, compose comment preserves the separation.

🪜 Evidence Audit

• Evidence: declaration present (L2 → L3 required for AC6 only, correctly residual)
• Achieved ≥ required for AC1–AC5: executable probe against fresh/stale/corrupt/wrong-role/missing fixtures, 41 focused tests, rendered Compose validation
• AC6 marked [L3-deferred] — the live long-child observation, correctly post-merge
• No evidence-class promotion; the 21-failure local-suite note is honest environmental accounting, not a hidden regression (CI green at exact head)

Findings: Pass.

N/A Audits — 📡 🔗

N/A across listed dimensions: no OpenAPI surface; no new convention (the inspector composes an existing primitive).

🧪 Test-Evidence & Location Audit

• Execution evidence: exact-head required CI green at 20db4cbe1aa4f8351bf702e8f304d5f5627138c0 (all checks); author's focused receipts (41 authority + 19 file-lease + rendered compose)
• Reviewer falsifier: none run — my concern was acquisition-semantics preservation under the new classify, which I verified by case analysis against my original predicate (fresh/stale/invalid outcomes identical); the spec set covers those cases directly, including the two acquisition-composition throws (wrong-role, future-dated)
• Test location: authorityLease.spec + daemon.spec — correct homes

Findings: Pass.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 96 — the right signal at the right boundary; shared classify; readFileLeaseHolder promoted with all five call sites updated consistently; no new config leaf.
• [CONTENT_COMPLETENESS]: 95 — complete honest evidence including the environmental failure account; the classify's three-state JSDoc is the durable contract.
• [EXECUTION_QUALITY]: 95 — the full falsifier set plus acquisition composition; CI green at exact head; compose render validated.
• [PRODUCTIVITY]: 95 — AC1–AC5 delivered, AC6 correctly L3-deferred with the observation protocol named.
• [IMPACT]: 85 — kills a false-negative that recommended restarting healthy work for ~20 minutes at a time; Docker health now means what operators think it means.
• [COMPLEXITY]: 40 — five files, one classify, one compose line; bounded.
• [EFFORT_PROFILE]: Quick Win — small surface, large operational correction.

Closing: The lease's pulse just became the plane's heartbeat in the place it matters most. Clean composition, clean semantics, clean evidence.
