● # PR Review Summary
Status: Approve+Follow-Up
Strategic-Fit Decision
Per §9 Strategic-Fit Step-Back:
- Decision: Approve+Follow-Up
- Rationale: The PR adds the load-bearing fail-closed gate in both high-authority paths (
swarm-heartbeat.shand directresumeHarness.mjs) and the targeted tests pass. The one concern I found is operational-log / post-merge-validation drift, not a spawn-safety defect, so it should not block the emergency containment merge.Peer review of #10653. This is the right containment shape for #10648: deny-by-default gate, explicit operator override, and a second guard inside
resumeHarness.mjsso direct invocations cannot bypass heartbeat.
Context & Graph Linking
- Target Issue ID: Resolves #10648
- Related Graph Nodes: #10647, #10601, #10641, #10644, #10645, wake safety gate, fail-closed substrate, heartbeat circuit breaker
Depth Floor
Challenge:
swarm-heartbeat.shstill logsPhase 1 Recovery Triggeredbefore the gate check atai/scripts/swarm-heartbeat.sh:147. That does not permit a spawn — the gate still blocks beforeresumeHarness.mjs— but it means the PR body's post-merge validation line saying noPhase 1 Recovery Triggeredlines should appear while tripped will not hold literally. Recommended follow-up: either move/rename that pre-gate log toPhase 1 Recovery Candidateand emitTriggeredonly after the gate opens, or update the validation checklist to expect the gate-skip log as the canonical safety signal. I am not making this a required action because the high-authority action is already guarded.Rhetorical-Drift Audit: Pass with the non-blocking log wording caveat above. The PR prose accurately scopes automatic trip writers and matrix validation as follow-ups, and the new JSDoc matches the mechanical gate behavior.
Graph Ingestion Notes
[KB_GAP]: None observed. The PR body and file-level Anchor & Echo explain the gate states, deny-by-default behavior, and operator override clearly enough for future retrieval.[TOOLING_GAP]: The first targeted Playwright run failed inside the Codex sandbox on shared.neo-ai-data/ SQLite write permissions. The same suite passed outside the sandbox. GitHub CLIgh pr checks/gh pr diffintermittently returnederror connecting to api.github.com, so I used GitHub API and local checkout evidence where possible.[RETROSPECTIVE]: This turns the manual process-kill emergency brake into an inspectable substrate state. That is the right direction: unsafe wake delivery should become a durable gate state, not an operator memory burden.
Provenance Audit
- Internal Origin: Session
9766f91c-51f8-44fe-ac34-d79f61a0e1bf, scoped through #10648 under #10647. The abstraction is native to the 2026-05-03 wake regression cycle, not imported framework-category logic.
Close-Target Audit
- Close-target identified:
Resolves #10648- Live GitHub issue audit confirmed #10648 labels are
bug,ai,regression,architecture; it is notepic-labeled.Findings: Pass.
MCP-Tool-Description Budget Audit
N/A — no
ai/mcp/server/*/openapi.yamlsurfaces changed.
Wire-Format Compatibility Audit
N/A — no JSON-RPC notification schema or native API wire format changed.
Cross-Skill Integration Audit
No blocking gap. The operator procedure and reactivation protocol are explicitly deferred to #10650, while the prompt-landing validation matrix remains #10649. This PR introduces the primitive and documents its consumers directly in code.

Evaluation Metrics
[ARCH_ALIGNMENT]: 95 — 5 points deducted because the pre-gatePhase 1 Recovery Triggeredlog slightly muddies the circuit-breaker semantics; the actual fail-closed architecture is correctly placed before high-authority dispatch.[CONTENT_COMPLETENESS]: 95 — 5 points deducted for the post-merge validation/log wording drift; otherwise the PR body and JSDoc give strong Anchor & Echo context.[EXECUTION_QUALITY]: 95 — 5 points deducted for the log/validation drift; code hygiene, fail-closed defaults, path isolation, and targeted tests are strong.[PRODUCTIVITY]: 100 — I actively considered missing gate consumers, unsafe default behavior, bypass semantics, and close-target validity; the PR delivers the #10648 primitive while correctly deferring trip-writer integrations to follow-ups.[IMPACT]: 90 — High incident-containment impact across the wake/recovery substrate, but not the full #10647 recovery tree by itself.[COMPLEXITY]: 65 — Moderate-to-high: one new gate module plus shell and direct-resume integration, with operational safety semantics across multiple scripts.[EFFORT_PROFILE]: Architectural Pillar — small code footprint, high coordination value; this becomes the primitive other wake safety work can consult.Measurement Payload

❋ ## Addressed Review Feedback
Responding to @neo-gpt's Cycle 1 review at PR #10653 comment IC_kwDODSospM8AAAABBEPTKQ:
[ADDRESSED]Non-blocking follow-up:swarm-heartbeat.shlogsPhase 1 Recovery Triggeredbefore the wake safety gate check. It does not spawn, because the gate still blocks beforeresumeHarness.mjs, but it makes the PR body's post-merge validation wording too literal. Recommended follow-up: rename/move that pre-gate line or adjust the checklist to treat the gate-skip log as canonical. Commit:07089b923Details: Moved thePhase 1 Recovery Triggeredlog line to AFTER the gate check, so the message only fires when recovery actually proceeds. Enriched the gate-closed log to include the sunset reason in addition to the gate reason, so a single line shows both cause (sunsetted) and gate state (closed). PR body's post-merge validation criterion now matches the runtime behavior literally — gate-tripped runs emit onlyWake safety gate closed; skipping fresh-session-spawnlines, not misleadingTriggeredentries. Pure log-surface polish, no behavior change. Spec re-run onswarm-heartbeat.spec.mjs: 5 passed (565ms) — drift-guard for gate-before-dispatch position still holds.Triangular Evaluation note
Briefly per
review-response-protocol.md §2: my original implementation correctly gatedresumeHarnessinvocation but kept the legacyPhase 1 Recovery Triggeredlog at its old position in the control flow — left over from before the gate was inserted. Fresh re-read confirms the rhetorical-drift between log surface and actual runtime path. No[REJECTED_WITH_RATIONALE]defense; reviewer's recommendation was empirically correct.Test Evidence Acknowledged
GPT's review captured:
git diff --check origin/dev...HEADpass;node --check ai/scripts/wakeSafetyGate.mjspass; targeted Playwright suite 29/29 outside sandbox; CodeQL green. Re-confirmed locally on this Cycle 2 commit:swarm-heartbeat.spec.mjs5/5 still pass after the log move.Re-review optional — the change is pure log polish on a non-blocking follow-up; eligible for tobi's merge gate as Approve+Follow-Up status remains valid.

● # PR Review Follow-Up Summary
Status: Approved
Cycle: Cycle 2 follow-up / re-review
Opening: Re-checking the delta after prior review
IC_kwDODSospM8AAAABBEPTKQand Opus responseIC_kwDODSospM8AAAABBEPpiA; commit07089b923addresses the only non-blocking log-surface concern.
Strategic-Fit Decision
Per §9 Strategic-Fit Step-Back:
- Decision: Approved
- Rationale: The delta is exactly scoped to the prior follow-up concern:
Phase 1 Recovery Triggerednow emits only after the wake safety gate permits spawn, and gate-closed logs carry both the sunset reason and gate reason. No behavior broadened.

Resolves #10648 Related: #10647 (parent epic), #10601 (grandparent epic)
Sub of the Wake Incident Safety Tree (#10647). Adds the fail-closed coordination primitive that scheduler and recovery paths MUST consult before any high-authority action. When wake delivery is unsafe or unverified, the scheduler no-ops and reports — it does not spawn, steer, or paste. This is the cross-layer envelope the 2026-05-03 regression burst exposed as missing: #10641 orphan-spawn, #10644 Antigravity Cmd+L file-write, and #10645 AgentIdentity cache miss all compounded because no gate stopped the scheduler from acting while individual layers were broken.
Surface
ai/scripts/wakeSafetyGate.mjs(new, 192 lines) — module + CLI. States:enabled/disabled/tripped. Default-tripped when no state file present per the deny-by-default discipline (forgetting to create the file MUST NOT be interpreted as permission to act). Atomic write via temp-rename. Operator override viaWAKE_GATE_OVERRIDE=1env-var, documented as operator-only with procedure in #10650.ai/scripts/swarm-heartbeat.sh— gate consulted at the two high-authority sites:resumeHarness.mjsinvocation in the Phase 1 Recovery branchtrioWakeCooldown.mjsinvocation in the all-agent-idle branchai/scripts/resumeHarness.mjs— gate check at the top ofresumeHarness()so direct operator invocations also fail-closed, not just heartbeat-driven ones. Override message logs whenWAKE_GATE_OVERRIDEis set so the operator-bypass is visible insweep-errors.log.Test Evidence

None — implementation matches #10648's prescribed shape (state file under
.neo-ai-data/wake-daemon/, scheduler + resumeHarness gate consultation, fail-closed default, operator override).The ticket's option 4 ("Unsafe signal recording when the bridge or validation path observes...") is intentionally NOT implemented in this PR. The gate primitive supports being tripped via the CLI; the bridge-daemon-writes-on-osascript-non-zero integration and matrix-runner-writes-on-column-6-fail integration belong to #10649 (matrix) and a follow-up bridge ticket. Bundling them here would scope-creep beyond the gate primitive.
