Coordination from #13767 / #13769 after Ada's overlap ping: I checked this diff against the typed-skip accounting leaf. The two PRs are complementary, not duplicates.
#13768currently records a watchdog-released hung holder as a HealthServiceskippedevent through the injectedrecordOutcomeseam.#13769fixes the separate task-state surface: Dream typedskippedoutcomes must useTaskStateService.markSkipped()instead ofmarkCompleted(), so no-op/deferred work does not advancelastSuccessAt.
Non-blocking for this seam-only PR: when the final daemon-loop wiring lands, keep the two-surface shape together. A watchdog release should record health skipped for observability and also use a non-success task-state cleanup path, e.g. markSkipped(owner), unless that wiring deliberately documents why the released owner has no task-state row to clear. That prevents the monitor from freeing the lease while durable task-state still looks running or recently successful.
PR Review Summary
Status: Request Changes
🪜 Strategic-Fit Decision
Per §9 Strategic-Fit Step-Back:
- Decision: Request Changes
- Rationale: The integration shape is right for the hung-lease watchdog, and the typed outcome correction to
failedis correct. The current head still has two fail-safe defects that can either force-release without four consecutive valid samples or let watchdog seam failures escapetick(), so this is not mergeable as a live-orchestrator stability slice yet.
Thanks for tightening the vocabulary boundary. The failed outcome is the right direction; the blockers below are runtime safety and close-target reconciliation, not a rejection of the service shape.
🧭 Patch-Blind Premise Snapshot
- Inputs Read Before Patch: #13766, changed-file list, current
devleaseWatchdog.mjs, the newleaseMonitor.mjsand spec, PR close-target commit log,#13765vocabulary boundary, local exact-head checkout05f3647afaf4241b2bd39c0f1ca4bb3158def6e8, and current-head CI. - Expected Solution Shape: A correct slice should be a seam-injected monitor driven at minutes cadence, should only release after a consecutive window of valid idle CPU samples, and should not let watchdog I/O/reporting seam failures break the orchestrator loop. Test isolation should cover both the nominal hung-holder path and mixed bad-data / seam-failure cases.
- Patch Verdict: The module shape matches the expected slice, but the implementation contradicts the fail-safe evidence boundary at
leaseMonitor.mjslines 80-86 and the no-throw contract at lines 86-90. The ticket body also still carries the oldskippedclose-target vocabulary while the PR correctly recordsfailed.
🕸️ Context & Graph Linking
- Target Epic / Issue ID: Resolves #13766
- Related Graph Nodes: #13624, #13761, #13765
🔬 Depth Floor
Challenge: The fail-safe contract currently treats a non-finite sample as a no-op return, but it preserves the prior per-pid idle window. A sequence of 0,0,0,NaN,0 releases the lease even though there were not four consecutive valid idle samples. That is the exact class of bad-data false positive this watchdog must avoid.
Rhetorical-Drift Audit (per guide §7.4):
- PR description: corrected the shipped outcome to
failed, matching the#13765vocabulary boundary. - Anchor & Echo summaries:
tick()saysNever throws, but release/outcome seam exceptions still throw. - Linked anchors: #13766 still says the watchdog records
skipped; the PR now correctly recordsfailed.
Findings: Required Actions 2 and 3 below.
🧠 Graph Ingestion Notes
[KB_GAP]: N/A.[TOOLING_GAP]: The required prior-art Memory Core sweep was degraded during review:query_summariesfailed with the embedding write-canary timeout, so I grounded this review from live GitHub/source evidence instead.[RETROSPECTIVE]: Good vocabulary separation is not enough by itself; watchdog safety also needs invalid telemetry to break the consecutive-evidence window and seam failures to stay contained.
N/A Audits — 📑 📡 🔗
N/A across listed dimensions: this PR adds an internal orchestrator service and unit spec, with no external contract ledger, OpenAPI MCP tool description, or cross-skill workflow convention surface.
🎯 Close-Target Audit
- Close-targets identified: #13766
- #13766 confirmed not
epic-labeled: labels areai,architecture,model-experience.
Findings: Close target exists and is a leaf, but the issue body/AC still says recordTaskOutcome(..., skipped, ...) while the PR now correctly records failed. Reconcile the close-target body so the graph does not retain the superseded vocabulary as the delivered contract.
🪜 Evidence Audit
- PR body contains an
Evidence: L2declaration line. - Achieved evidence does not yet cover the fail-safe edge cases found by review.
- Two-ceiling distinction is acceptable for this slice: live daemon-loop wiring remains explicitly out of scope.
Findings: Local L2 evidence is green for the shipped six tests, but the added falsifiers below expose uncovered safety cases that must be pinned before merge.
🧪 Test-Execution & Location Audit
- Branch checked out locally at exact head
05f3647afaf4241b2bd39c0f1ca4bb3158def6e8. - Canonical Location: new AI unit spec is under
test/playwright/unit/ai/daemons/orchestrator/services/. - Ran
node --check ai/daemons/orchestrator/services/leaseMonitor.mjs. - Ran
node --check test/playwright/unit/ai/daemons/orchestrator/services/leaseMonitor.spec.mjs. - Ran
npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/services/leaseMonitor.spec.mjs— 6 passed. - Manual falsifier:
[0,0,0,NaN,0]released the lease on the fifth tick; expected no release because the bad sample breaks the valid consecutive-idle window. - Manual falsifier:
releaseLeaseandrecordOutcomeexceptions escapetick()after the fourth idle sample; expected no throw or a deliberately narrowed caller contract. - Current-head CI is green: unit, integration-unified, lint, CodeQL, PR body lint, retired-primitives check all pass.
Findings: Tests pass but coverage is incomplete for the fail-safe contract.
📋 Required Actions
To proceed with merging, please address the following:
- Break or reset the per-pid idle history on non-finite CPU readings and sample failures. Add a regression test for
0,0,0,NaN,0proving the monitor does not force-release without four consecutive valid idle samples. - Make
tick()honor its no-throw / fail-safe contract acrossreleaseLeaseandrecordOutcomeas well, or explicitly narrow the contract and prove the caller contains those exceptions. Given this is a watchdog inside the orchestrator loop, the safer shape is catch-and-return terminal action tags such asrelease-failed/outcome-record-failed, with tests. - Reconcile #13766 so its body/AC records the now-correct
failedoutcome instead of the supersededskippedoutcome. The PR body is correct; the close-target substrate is stale.
📊 Evaluation Metrics
[ARCH_ALIGNMENT]: 80 - The seam-injected service and slow-cadence boundary match the watchdog architecture, but the invalid-sample window and thrown seam failures weaken the stability contract.[CONTENT_COMPLETENESS]: 75 - JSDoc and PR body explain the intended contract, butNever throwsis not true yet and #13766 still carries the oldskippedAC.[EXECUTION_QUALITY]: 55 - Exact-head tests and CI pass, but two focused falsifiers expose merge-blocking fail-safe defects.[PRODUCTIVITY]: 65 - The main service slice is mostly delivered, but it cannot safely close #13766 until the fail-safe gaps and close-target drift are fixed.[IMPACT]: 85 - This is a live orchestrator stability guard for the post-reboot stuck-embedding class of failures.[COMPLEXITY]: 45 - Small file footprint and clean seams, but the edge semantics are subtle because bad telemetry must never become release evidence.[EFFORT_PROFILE]: Heavy Lift - High operational impact with moderate code size but safety-critical behavior.
Once those three items are addressed, this should be a narrow re-review: rerun the leaseMonitor spec plus the two falsifier shapes above and recheck #13766 vocabulary.
PR Review Follow-Up Summary
Status: Approve
Cycle: Cycle 2 follow-up / re-review
Opening: Re-checking my prior CHANGES_REQUESTED review on #13768 against head 14d43c806; the three Required Actions are now closed and the current-head evidence supports approval.
🧭 Patch-Blind Premise Snapshot
For follow-ups, ground the expected shape in the prior review anchor plus the current delta. Do not let the author's response framing replace the source-of-authority substrate.
- Inputs Read Before Patch: Prior review
PRR_kwDODSospM8AAAABDpb-cA, current #13766 body, current #13768 body, exact-head source/spec forleaseMonitor, current-head GitHub checks, HealthServicerecordTaskOutcomecontract, and focused local leaseMonitor unit run. - Expected Solution Shape: The monitor should remain seam-injected and slow-cadence by construction; bad/non-finite samples must reset the consecutive-idle window; release/outcome seam failures must not escape
tick(); and the close-target vocabulary must usefailedfor ran-then-hung holders rather thanskipped. - Patch Verdict: Matches. The current head resets history on bad samples, returns
release-failedfor release/record exceptions, keeps history for retry after failed release, recordsfailedfor hung holders, and #13766 has been reconciled to thefailedvocabulary plus fail-safe contract.
🪜 Strategic-Fit Decision
Per §9 Strategic-Fit Step-Back:
- Decision: Approve
- Rationale: This remains the right service-slice boundary for #13624: a pure, seam-injected lease monitor with no daemon-loop wiring yet. The cycle-2 delta closes the false-positive and no-throw gaps without expanding the blast radius.

- Files changed:
ai/daemons/orchestrator/services/leaseMonitor.mjs;test/playwright/unit/ai/daemons/orchestrator/services/leaseMonitor.spec.mjs - PR body / close-target changes: #13766 and the PR body now both say hung holders record
failed, bad samples reset the idle window, and release/record seam exceptions returnrelease-failedwithout breaking the loop. - Branch freshness / merge state: clean; unit/integration/lint/CodeQL all green on current head.
✅ Previous Required Actions Audit
For each prior Required Action, mark the current state:
- Addressed: Break/reset per-pid idle history on non-finite CPU readings and sample failures — evidence:
history.delete(pid)on sample failure/non-finite sample, plus the0,0,0,NaN,0regression test. - Addressed: Honor
tick()no-throw/fail-safe contract for release and outcome seams — evidence: release + record are inside the sametryblock returning{action: 'release-failed', pid, owner}, with separate tests forreleaseLeaseandrecordOutcomeexceptions. - Addressed: Reconcile #13766 vocabulary — evidence: the issue body now says
recordTaskOutcome(..., 'failed', ...), namesskippedas the never-ran state, and documents the fail-safe behavior.
🔬 Delta Depth Floor
- Delta challenge: The remaining subtlety is async outcome seams, but the live
HealthService.recordTaskOutcome()contract is synchronous, and the PR's injected seam docs specifyrecordOutcome (...) -> void. This PR is therefore consistent with its current integration target. If a future async outcome sink is introduced, that belongs to the daemon-loop wiring/follow-up contract, not this merge gate.
🔎 Conditional Audit Delta
📑 Contract Completeness Audit
- Findings: Pass. #13766, #13768, the service JSDoc, and the spec now describe the same contract: slow-cadence monitor, bad data resets the window, hung holder records
failed, and seam failures fail safe.

Summary
The INTEGRATION of #13761's pure hung-lease watchdog into the live orchestrator: a periodic lease-monitor that ps-samples the active heavy-lease holder's cpu, then force-releases + records a
skippedoutcome when the holder is HUNG (alive + within-TTL but sustained-idle — the 2026-06-21 01:17 incident the pid/TTL stale-check can't catch).Builds on #13761 (now MERGED)
#13761 (the pure
isHungLeaseHoldercarve) merged to dev at 12:23, so this bases cleanly on dev — the diff is exactly the 2 newleaseMonitorfiles (it importsisHungLeaseHolderfrom dev).Deltas
ai/daemons/orchestrator/services/leaseMonitor.mjs(new):createLeaseMonitor({inspectLease, sampleCpuPercent, releaseLease, recordOutcome, ...}) → {tick}. Factory with injected seams (fully unit-testable) + a closure per-pid cpu-history. Eachtick(): inspect the active lease → ps-sample the holder pid → push to history →isHungLeaseHolder→ if hung:releaseLease+recordOutcome('failed'). Fail-SAFE (a bad inspect/sample never force-releases).tick()at the minutes-scale sample interval, NOT the 250ms daemon tick) — sominConsecutiveIdle × interval= minutes, never the 750ms that would false-positive a working holder and re-create the DRAIN.'failed'outcome ({reason, failurePhase: 'hung-lease-holder'}), NOT'skipped'(= never-ran). This deliberately does not overloadskippedinto a green-looking no-op; it uses the EXISTINGrecordTaskOutcome'failed'state (the convergence may add a hung-specific typed-outcome later).Out of scope (the last bit)
The daemon-loop hook (the 1-line
monitor.tick()wiring at the sample interval) lands last — minimizing the live-daemon blast.Test Evidence
Evidence: L2 — 9 unit tests green (
