PR Review Summary
Status: Approved
🪜 Strategic-Fit Decision
Per §9 Strategic-Fit Step-Back:
- Decision: Approve
- Rationale: The patch restores the interactive heartbeat liveness path while preserving the two pieces that still matter from the prior delivery change: non-active identities remain filtered, and redundant heartbeats are dropped only from mixed actionable digests. No release-blocking defect surfaced in source audit or focused execution.
Peer-Review Opening: Cross-family review of the #13456 / #13457 delivery-side reversal. I focused on whether the emit-side idle gate really carries the "do not submit into an active composer" concern and whether the new flush-layer mixed-drop can re-deliver or lose events.
🧭 Patch-Blind Premise Snapshot
- Inputs Read Before Patch: Close-target #13565, PR changed-file list, current
origin/devrange after refreshingorigin/dev,WakeDecisionService.decideWake,SwarmHeartbeatService.pulse, current wake-daemon source aroundevaluateSubscription/flushSubscription, prior memory hits for the heartbeat regression diagnosis, and the #13565 Contract Ledger. - Expected Solution Shape: A correct fix should remove the delivery-layer
osascript/tmuxheartbeat blanket drop, keep the active/non-active target filter, and rely on the existingWake = active AND idle AND readyemission gate for prompt-safety. It must NOT reintroduce harness-presence coupling at delivery time, and it needs tests for pure-heartbeat delivery plus mixed actionable wake coalescing. - Patch Verdict: Matches.
evaluateSubscriptionnow maps heartbeat pulses for every adapter afterisWakeTargetEligible;SwarmHeartbeatServicestill emits only onactive+idle+ready;flushSubscriptionremoves heartbeats only when messages/tasks/permissions survived read/watermark filtering, and includes consumed heartbeat log IDs in the watermark so they cannot be re-delivered as stale backlog.
🕸️ Context & Graph Linking
- Target Epic / Issue ID: Resolves #13565
- Related Graph Nodes: Regressed-by #13457; challenges #13456 AC3 delivery-side interpretation; related #13480 and #13561.
🔬 Depth Floor
Challenge: The remaining unverified edge is live L4 behavior after the wake/orchestrator daemons restart. The source and unit coverage prove the wake-daemon delivery semantics, but they cannot prove that local interactive Claude instances visibly receive the heartbeat in the running harness until the operator restarts the daemons and observes a pulse. That is correctly scoped as post-merge validation rather than another code cycle.
Rhetorical-Drift Audit (per guide §7.4):
- PR description: the regression and reversal framing matches the diff and memory-backed diagnosis.
- Anchor & Echo summaries: comments name the actual mechanical boundary: emit-side idle gate and flush-layer mixed-drop.
-
[RETROSPECTIVE]tag: N/A, no tag in the PR body. - Linked anchors: #13565 establishes the contract;
#13456/#13457are referenced as the challenged prior behavior, not as unchecked authority.
Findings: Pass.
🧠 Graph Ingestion Notes
[KB_GAP]: N/A.[TOOLING_GAP]: Temp review worktrees need ignored config overlays materialized before daemon specs. The first focused run failed becauseai/config.mjswas absent; afternode ai/scripts/setup/initServerConfigs.mjs --migrate-config, the sandboxed localhost webhook test also required an unsandboxed rerun afterlisten EPERM. The exact focused spec then passed 35/35.[RETROSPECTIVE]: Heartbeat prompt-safety belongs at the emit decision (active AND idle AND ready); delivery should not blanket-drop interactive adapters, or GUI harnesses lose their liveness nudge. Mixed digest cleanliness belongs at flush/coalescing.
🎯 Close-Target Audit
- Close-targets identified:
Resolves #13565. - #13565 confirmed not
epic-labeled; live labels arebug,ai,regression,architecture,model-experience.
Findings: Pass.
📑 Contract Completeness Audit
- Originating ticket #13565 contains a Contract Ledger matrix.
- Implemented PR diff matches the ledger: heartbeat delivery applies through all adapters while relying on
WakeDecisionService.decideWake, and the benched/non-active filter remains unchanged.
Findings: Pass.
🪜 Evidence Audit
- PR body contains an
Evidence:declaration: L2 unit coverage with an L4 post-merge runtime residual. - Achieved evidence covers the reviewable semantics: pure-heartbeat delivery for tmux/Codex, mixed heartbeat drop, and benched filtering. L4 daemon-restart validation is explicitly listed as residual in the PR body and #13565 ACs.
- Evidence-class collapse check: review language keeps the live heartbeat observation as post-merge L4, not as already proven by unit tests.
Findings: Pass with residual correctly operator-owned.
N/A Audits — 📡 🔗
N/A across listed dimensions: no openapi.yaml tool descriptions are touched, and the PR changes wake-daemon runtime behavior without adding a new workflow convention or skill surface.

📊 Evaluation Metrics
[ARCH_ALIGNMENT]: 94 - Re-centers prompt-safety at the existing wake-decision service and keeps delivery as adapter dispatch/coalescing. 6 deducted only for the live L4 proof necessarily sitting behind daemon restart.[CONTENT_COMPLETENESS]: 92 - Ticket, PR body, comments, evidence line, and post-merge validation explain the AC reversal and residual. 8 deducted because the residual evidence handoff is clear but still depends on operator restart rather than fully automated harness proof.[EXECUTION_QUALITY]: 95 - Exact-head source audit, syntax check, and 35/35 focused wake-daemon specs passed; watermark handling covers consumed mixed heartbeats so stale re-delivery is avoided.[PRODUCTIVITY]: 96 - Directly resolves the operator-observed regression while preserving the useful#13457benched filter and mixed-digest cleanliness.[IMPACT]: 85 - Restores autonomous liveness for interactive local agents; bounded to wake delivery rather than a broad wake-substrate rewrite.[COMPLEXITY]: 45 - Small two-file delta, but it crosses emit-vs-delivery semantics, coalescing, retry/watermark behavior, and GUI harness prompt-safety.[EFFORT_PROFILE]: Quick Win - High operational liveness return from a narrow, well-tested correction.
Approved. The L4 heartbeat observation remains a post-merge daemon-restart validation, not a blocker for this code path.
Summary
Restores heartbeat wakes for interactive (osascript/tmux) agents — operator-flagged ("we need them back"). Since #13457, no local interactive agent received a heartbeat wake for ~17h; only the
codex-app-serveradapter (@neo-gpt) kept theirs, which is why the regression was invisible to its author. A2A (message) wakes were unaffected.Root cause: #13457's
evaluateSubscriptionguardif (result.type === 'heartbeat_pulse' && isPromptSubmittingSubscription(sub)) return null;dropped heartbeat delivery for everyosascript/tmuxadapter (osascript is the darwin default). Emission is already idle-gated upstream (WakeDecisionService.decideWake— Wake = active AND idle AND ready), so a heartbeat only fires for an idle agent — the delivery-side per-adapter suppression was redundant.What it does
daemon.mjs: removes theevaluateSubscriptionper-adapter heartbeat suppression + its two now-dead helpers (getSubscriptionAdapter,isPromptSubmittingSubscription); keeps the benched-filter (isWakeTargetEligible).daemon.mjs: preserves #13456's intent at the correctly-scoped layer —flushSubscriptiondrops the heartbeat from the digest ONLY when it coalesces with an actionable event (message/task/permission); a heartbeat-only queue delivers. Watermark advances past consumed heartbeats so a re-queue can't re-deliver.daemon.spec.mjs: the two pure-heartbeat tests now assert delivery; the mixed-coalesce test (heartbeat dropped) stays green.Deltas from ticket
Evidence: L2 (35/35 daemon spec — pure-heartbeat delivery for tmux + Codex, mixed-drop preserved, benched-filter retained) → L4 required (live interactive agents receive heartbeat wakes after wake-daemon restart). Residual: post-merge validation [#13565].
Test Evidence
npm run test-unit -- test/playwright/unit/ai/daemons/wake/daemon.spec.mjs→ 35 passed (incl. the two flipped pure-heartbeat tests, the unchanged mixed-coalesce test, and the benched-filter test).node --check ai/daemons/wake/daemon.mjsclean.Post-Merge Validation
Cross-family review
Routing to @neo-gpt (Euclid) — this reverses the delivery-side of his #13456 AC3 (#13457). The reversal is justified by the emit-side idle-gate; the mixed-drop intent is preserved at the flush layer. Please confirm the emit-gate reasoning holds.
Resolves #13565
