PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: This is a focused test-only hardening PR for a freshly extracted shared helper. The close-target AC asks for direct pure-function branch coverage, and the patch supplies exactly that without touching hook behavior or expanding scope.

Peer-Review Opening: Peer review of PR #13660. The test shape matches the issue: pin the shared no-hold decision helper directly, leave harness adapter behavior to the existing hook specs, and avoid runtime/I/O coupling.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: Issue #13659; changed-file list; current dev source for ai/scripts/lifecycle/stopHookDecision.mjs; sibling hook specs under test/playwright/unit/hooks/; Claude and Codex hook consumers; PR body/conversation; exact head 8d880631a7b95eff43b120867ac11fa2a93f3ea7; Memory Core prior-art queries and KB query, which returned no direct same-day helper mapping.
• Expected Solution Shape: Correct coverage should add one hermetic unit spec near the hook tests, import the pure helper directly, and exercise the parseOutcomeToVerdict, isOperatorInLoop, and decideStopHookAction branches from the ticket. It should NOT hardcode hook adapter I/O, transport behavior, or duplicate full hook spawning tests; test isolation should remain pure function, no hook, no filesystem/process coupling.
• Patch Verdict: Matches. The diff adds only test/playwright/unit/hooks/stopHookDecision.spec.mjs, covers all issue-listed branches including Codex blockInjectionSupported:false suffix/bare paths, and makes no production behavior changes.

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

Documented search: I actively looked for branch omissions across parse/operator/action paths, wrong test placement versus the hook sibling tests and unit-test guide, and close-target or commit-message overclaim. I found no concerns.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: framing matches the test-only diff and the helper source comments.
• Anchor & Echo summaries: no new production summaries; the test docblock accurately scopes the anti-drift purpose.
• [RETROSPECTIVE] tag: N/A, none present.
• Linked anchors: issue #13659 and PR references support the follow-up/test-only framing.

Findings: Pass.

🧠 Graph Ingestion Notes

• [KB_GAP]: No PR author gap. Reviewer KB search did not yet surface same-day stopHookDecision context, so review grounding came from live ticket/source/PR state.
• [TOOLING_GAP]: Reviewer-side sandbox gh pr checks hit a transport error; escalated retry succeeded and confirmed all current checks pass.
• [RETROSPECTIVE]: Direct helper coverage is the right anti-drift layer here: it pins shared no-hold semantics without coupling tests to either harness adapter.

🎯 Close-Target Audit

For every issue named as close-target, verify it does NOT carry the epic label:

• Close-targets identified: #13659
• #13659 labels verified live: ai, testing, model-experience; no epic label.
• Commit log checked: ticket-bearing subject only; no stale Closes / Fixes / Resolves magic keyword in commit body.

Findings: Pass.

📑 Contract Completeness Audit

• Originating ticket (or parent epic) contains a Contract Ledger matrix
• Implemented PR diff matches the Contract Ledger exactly (no drift)

Findings: N/A — this PR adds pure unit coverage only and does not introduce or modify a public/consumed contract.

🪜 Evidence Audit

• PR body contains an Evidence: declaration line.
• Achieved evidence is sufficient for the close-target AC: direct unit coverage of pure functions, no runtime/harness residual.
• Evidence-class language does not promote unit coverage into host-runtime proof.

Findings: Pass / N/A boundary — the close-target ACs are fully covered by direct unit tests.

📡 MCP-Tool-Description Budget Audit

For every modified or added OpenAPI tool description:

• Single-line preferred — block-literal (|) descriptions justified by content, not authorial habit
• No internal cross-refs (no ticket numbers, Phase sequencing, session IDs, or memory anchor names in the description payload)
• No architectural narrative — descriptions describe call-site usage (what + when-to-use + when-not-to-use)
• External standard URLs OK — citing canonical specs is acceptable
• 1024-char hard cap respected — approaching it is a red flag

Findings: N/A — no OpenAPI/MCP tool description surface touched.

🔗 Cross-Skill Integration Audit

• Does any existing skill document a predecessor step that should now fire this new pattern?
• Does AGENTS_STARTUP.md §9 Workflow skills list need updating?
• Does any reference file mention a predecessor pattern that should now also mention the new one?
• If a new MCP tool is added, is it documented in the relevant skill's reference payload?
• If a new convention is introduced, is the convention documented somewhere (when it applies, how it fires)?

Findings: N/A — no skill, workflow convention, MCP surface, or new architectural primitive is introduced; this is direct coverage for an existing helper.

🧪 Test-Execution & Location Audit

• Branch checked out locally in /Users/Shared/codex/neomjs/neo/tmp/review-13660-gpt at exact head 8d880631a7b95eff43b120867ac11fa2a93f3ea7.
• Canonical Location: test/playwright/unit/hooks/stopHookDecision.spec.mjs sits with the existing hook specs and targets hook/lifecycle helper behavior.
• Ran the specific changed test file.
• Current GitHub checks verified green.

Findings: Tests pass — npm run test-unit -- test/playwright/unit/hooks/stopHookDecision.spec.mjs → 15/15 passed locally; GitHub checks all successful.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 100 - The test targets the shared helper boundary directly and preserves the adapter-vs-helper split; both Claude and Codex consumers were checked for that boundary.
• [CONTENT_COMPLETENESS]: 100 - PR body includes the leaf close target, evidence line, deltas, test evidence, and residual posture; the new test has an orienting docblock and no production JSDoc obligations are introduced.
• [EXECUTION_QUALITY]: 100 - Exact-head checkout, local focused test run passed 15/15, current CI is green, and the assertions cover every branch named in the ticket AC.
• [PRODUCTIVITY]: 100 - Fully satisfies #13659 without behavior churn or broader harness coupling.
• [IMPACT]: 70 - Test-only change, but it protects a cross-harness no-hold source-of-authority from future drift.
• [COMPLEXITY]: 20 - One new pure-function test file, no production mutation, no runtime setup.
• [EFFORT_PROFILE]: Quick Win - High confidence and meaningful guardrail value from a small, focused coverage addition.

Approved. This is merge-eligible for the human gate.
