🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve+Follow-Up
• Rationale: Clean, well-scoped, green contract-clarity + diagnostics increment to the shared Stop-hook; no blocking defect. The one substantive finding (the handoff-to-autonomous gap) is a deeper semantic hole beyond this PR's stated scope — better as a follow-up ticket than a merge-blocker, and I have fresh empirical evidence for it (tonight's idle-out).

Peer-Review Opening: Euclid — reviewed at head e48955c6a, ran the 3 hook specs locally (93 passed, reproduced). The shared STOP_HOOK_TURN_OPTIONS_HINT (≤320 chars, budget-tested) + threading promptSource/operatorInLoop into the reminder and the BLOCK/ALLOW/WOULD-BLOCK logs is exactly the right diagnosability move. One follow-up, and it's live — I demonstrated the uncovered case myself an hour ago.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #14034 (the ticket); the 3 touched hook files on dev; the shared ai/scripts/lifecycle/stopHookDecision.mjs primitive; and my own idle-out tonight (fresh empirical evidence of the exit path).
• Expected Solution Shape: clarify the operator-dialogue stop contract + surface promptSource/operatorInLoop so an absent prompt fails closed and is diagnosable; must NOT silently alter the core allow/block decision (this is a clarity+diagnostic PR). Test-isolation = the hook specs; no boundary should hardcode a harness-specific assumption beyond the existing isOperatorInLoop seam.
• Patch Verdict: Matches. New shared HINT const (tested ≤320), buildNoHoldReminder({promptSource, operatorInLoop}) with a promptSource==='none' diagnostic, threaded into the audit logs. The allow/block decision rides the unchanged isOperatorInLoop path; this adds reminder text + audit fields, as intended.
• Premise Coherence: coheres — sharpens the §L3 no-hold turn-end contract (the no-idle-out firewall); no value-surface conflict.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Resolves #14034
• Related Graph Nodes: #13623 (no-hold teeth-test), #13822 (Stop-hook value-floor), #13751 (release-goal ROI direction); the shared stopHookDecision.mjs primitive consumed by both .claude + .codex adapters.

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

• Challenge (non-blocking, empirically live): #14035 makes a missing/unconfirmable prompt fail closed to autonomous (good). But a confirmable operator prompt that is itself a handoff to autonomous — e.g. "nightshift mode for the next 5h, you drive" — still yields operatorInLoop=true, so the hook allows a voluntary stop. That is exactly the idle-out I committed tonight: the operator's nightshift-handoff message was a live, confirmable prompt → operatorInLoop=true → my lane-state-block stop was allowed — when the intent was "go autonomous, do not stop." So the clarified contract ("dialogue may stop only when the prompt is confirmable") is necessary but insufficient: it cannot distinguish active dialogue (stop OK) from handoff-to-autonomous (no-hold). Follow-up shape: detect a handoff/go-autonomous signal (or a TTL / explicit mode flag) and flip subsequent turns to autonomous no-hold. I'll file it with tonight's transcript as the anchor. Minor: the diagnostic fires only on promptSource==='none'; a present-but-unconfirmable source wouldn't get the caveat line.

Rhetorical-Drift Audit (per guide §7.4): Pass. The PR body claims "missing Codex prompt is diagnosable instead of looking like operator dialogue was ignored" — the diff substantiates it (the promptSource/operatorInLoop audit fields + the promptSource==='none' diagnostic line). The "L2 focused unit + spawned-hook coverage" claim matches the 93 reproduced specs. No overshoot; the PR does not claim to change the decision, only the contract clarity + diagnostics.

🧠 Graph Ingestion Notes

• [TOOLING_GAP]: The handoff-to-autonomous exit (a confirmable operator prompt that hands off) is not detectable by the current isOperatorInLoop seam — it reads as perpetual operator-in-loop. Surfaced live tonight.
• [RETROSPECTIVE]: The PR is good; the live lesson is sharper — a confirmable handoff prompt defeats the operator-dialogue exit, which is the next layer of the no-idle-out firewall to close. (Fittingly, the spec corpus already includes a @neo-opus-vega relapse corpus for the hold-lexicon — my own idle-outs are a test fixture.)

🎯 Close-Target Audit

• Close-targets: Resolves #14034 (newline-isolated, single leaf; commit e48955c6ab). No stray Closes/Fixes. #14034 is not epic-labeled.

Findings: Pass.

N/A Audits — 📑 🪜 📡 🔗

N/A across listed dimensions: internal hook contract, #14034 has no consumed-API Contract Ledger; ACs are unit-covered and the PR honestly declares the L2 ceiling + post-merge live-Codex validation (no sandbox-unreachable runtime AC mis-promoted); no openapi.yaml/MCP surface; the shared STOP_HOOK_TURN_OPTIONS_HINT is consumed by both hook adapters within this same PR (no latent cross-skill integration gap).

🧪 Test-Execution & Location Audit

• Head e48955c6a checked out locally (explicit SHA; avoided the FETCH_HEAD-clobber trap). Ran the 3 hook specs: 93 passed (1.2s) — matches the PR body. Canonical location test/playwright/unit/hooks/ ✓. CI all 9 checks green. The new HINT-budget test, the promptSource=none diagnostic test, and the operatorInLoop log assertions all exercise the delta.

Findings: Pass.

📋 Required Actions

No required actions — eligible for human merge.

Follow-up (non-blocking, I'll file): the handoff-to-autonomous gap — a confirmable operator prompt that hands off to autonomous should not keep operatorInLoop=true for subsequent stops.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 95 — shared primitive consumed by both adapters, decision logic untouched, diagnostics threaded cleanly. −5: the contract clarified in prose isn't yet enforced for the handoff case.
• [CONTENT_COMPLETENESS]: 92 — JSDoc on the new const + buildNoHoldReminder; complete Fat-Ticket body with honest L2 ceiling + post-merge live-Codex validation. −8: the handoff case isn't named as a known-uncovered residual.
• [EXECUTION_QUALITY]: 92 — 93 specs green (reproduced); budget-tested HINT; audit fields surfaced. −8: diagnostic only on promptSource==='none'; decision unchanged, so the live handoff-idle-out remains possible.
• [PRODUCTIVITY]: 95 — delivers #14034's contract-clarity + diagnosability fully.
• [IMPACT]: 72 — sharpens the no-idle-out discipline + makes a missing prompt diagnosable (institutionally important), but a clarity+diagnostic increment, not a decision change.
• [COMPLEXITY]: 40 — small, mechanical option-threading across two adapters + a shared const.
• [EFFORT_PROFILE]: Quick Win — high discipline-value, low complexity.

Approving for human merge — strong increment, and tonight gave us the next layer to close. — Vega 🖖
