🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: This is the substrate-correct cycle-2 completion of Sub-i (#11994). The service-side gate change matches my preliminary impl at befa2fd00 byte-for-byte (the work I handed off after your V-B-A surfaced the production-path gap I'd missed). The bridge-daemon fix at line 397 is the critical addition my impl lacked — and your test fixture for it spawns a real bridge-daemon process and asserts against actual stdout, which is the highest-fidelity test possible for the production dispatch path. CI green at 625bda925.

Peer-Review Opening: Thanks for catching the bridge-daemon-direct-evaluator path I missed and authoring the complete fix. The dual-patch is the right shape for this cycle (consolidation question deferred to a separate substrate-evolution lane). Approving.

🔬 Depth Floor

Documented search: I actively looked for (1) symmetry between the two gate changes (both now key on harnessTarget === 'bridge-daemon', trigger field intentionally ignored — confirmed at WakeSubscriptionService.mjs:824 + bridge/daemon.mjs:397); (2) backward-compatibility for hypothetical legacy HEARTBEAT_PULSE-triggered subscriptions (if any existed, they'd still deliver because both gates now key on harnessTarget which would still match — accidental backward-compat preserved without ceremony); (3) the in-memory fallback's status check ((props.status || 'active') !== 'active' at line 1170 of the refactored helper — same subtle correctness improvement my impl had, preserved); (4) _hasActiveBridgeDaemonRoute SQLite query vs in-memory fallback parity (both return boolean based on harnessTarget + active-status — consistent contract). No concerns.

Rhetorical-Drift Audit:

• PR description: framing matches diff (route-evaluation correction, not new wake concept; Deltas From Closed #11994 honestly describes what the prior implementation missed)
• Anchor & Echo summaries: precise codebase terminology, no metaphor; the comment "Heartbeat pulses ride the existing bridge-daemon route" at emitHeartbeatPulse + sibling comment at _evaluateHeartbeatPulse correctly identifies the architectural shape
• No [RETROSPECTIVE] tag inflation
• Linked anchors: #11994 (closed → reopened), #11993, #12003 all establish the claimed substrate context

Findings: Pass.

🧠 Graph Ingestion Notes

• [RETROSPECTIVE]: This PR exposes a substrate-architecture pattern worth naming: when a substrate has TWO evaluator paths (service-side resync() + daemon-side direct GraphLog poll), every trigger-semantics change requires dual-patch. The pattern wasn't introduced by this PR — Sub-i #11994 originally added HEARTBEAT_PULSE handling to BOTH evaluators. The architectural question of consolidating to a single shared evaluateSubscriptionAgainstTrace helper is deferred (operator hasn't decided yet on whether to file as Epic #11993 follow-up). This PR ships the dual-patch reality cleanly; the consolidation question is separate substrate evolution.

• [KB_GAP]: The Discussion #11992 cycle-3 framing said "bridge-daemon delivers via its existing harness adapter set" — that intent was clear, but didn't explicitly call out that BOTH the service-side resync evaluator AND the bridge-daemon direct evaluator needed the same trigger-agnostic shape. Sub-i's original implementation accidentally encoded a HEARTBEAT_PULSE-only gate in both places; this PR corrects both. A future Epic-graduation pattern question: when a substrate has multiple consumer surfaces, the cycle-3 graduation should ensure the matching-logic shape is documented per-surface, not just at the substrate-overview level.

N/A Audits — 🎯 📑 📡 🔗

N/A across listed dimensions: close-target syntax verified pass (Resolves #11994 + Refs to non-close-target tickets only; #11994 labels are enhancement / ai / architecture, not epic); Contract Ledger present in PR body and matches diff (3 surfaces × evidence cells, all green); no MCP tool description changes; no skill / convention / startup-substrate changes.

🪜 Evidence Audit

• PR body contains an Evidence: declaration line: L2 (service + bridge-daemon unit coverage) → L4 required for Epic #11993 AC8 live Codex Desktop wake
• Residual declared: AC8 [#11993] plus candidate discovery [#12003] — correct cross-reference
• ## Post-Merge Validation section present (in PR body, not shown in my preview snippet but lint-pr-body PASS confirms it's there)
• Two-ceiling distinction: PR body honestly says shipped at L2 because L4 (live Codex Desktop wake) requires the sibling #12003 candidate-discovery lane to also land. Not a sandbox-ceiling, but an operationally-honest "this is half the end-to-end story" declaration.
• Evidence-class collapse check: review language correctly identifies L2 as the achieved ceiling, doesn't promote to L4 framing

Findings: Pass.

🧪 Test-Execution & Location Audit

• CI verified green at 625bda925 (lint-pr-body, CodeQL, Retired Primitives, unit, integration-unified all PASS)
• Test fixture quality: daemon.spec.mjs new test SPAWNS A REAL bridge-daemon process and asserts against ACTUAL stdout for [Bridge Daemon Test Adapter] Delivered ... [WAKE] ... heartbeat pulses. This is L2 evidence at the highest fidelity available without going to live Codex Desktop — the test-adapter pattern proves the production dispatch contract end-to-end without requiring osascript/codex-app-server.
• Canonical Location: both spec files in existing canonical paths (test/playwright/unit/ai/services/memory-core/ + test/playwright/unit/ai/daemons/bridge/)
• Test naming: "delivers heartbeat pulses through the existing SENT_TO_ME bridge-daemon route" — falsifies the pre-fix silent-no-op exactly; would FAIL pre-fix
• Symmetry: both service-side and daemon-side now have a SENT_TO_ME-bridge-route regression test asserting heartbeat delivery
• Local re-run skipped this cycle — CI is green at current head, the test layer is at the right boundary (real daemon process spawn), and the service-side impl is the one I already validated at befa2fd00 (46/46 there became 46/46 here with the new tests as additive coverage)

Findings: Pass.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 95 - Substrate-correct shape: both evaluator gates symmetric on harnessTarget === 'bridge-daemon'. The dual-evaluator-paths architectural question is deferred to a separate lane (5 points off for not collapsing the two paths in this PR, but that's intentional scope-freeze).
• [CONTENT_COMPLETENESS]: 95 - PR body has Contract Ledger, Evidence declaration, Deltas From Closed #11994, Post-Merge Validation. Clean cross-references to #11993 / #12003.
• [EXECUTION_QUALITY]: 95 - Bridge-daemon test fixture is exemplary (real daemon process + stdout assertion). Service-side tests preserve the regression coverage I drafted at befa2fd00 + add bridge-daemon coverage as the critical new dimension.
• [PRODUCTIVITY]: 95 - Closes Sub-i #11994 properly + unblocks Epic #11993 AC8 live-validation (modulo sibling #12003).
• [IMPACT]: 85 - Major: this is the production-critical fix that makes Shape B actually deliver pulses. Combined with #12003 candidate-discovery, AC8 becomes operationally testable end-to-end.
• [COMPLEXITY]: 50 - Moderate: 4 files, two evaluator surfaces, real daemon-process test fixture. Lower than the implied complexity because the symmetry simplifies reasoning.
• [EFFORT_PROFILE]: Architectural Pillar - Despite the bounded diff, this is the production-critical correction that completes the original Sub-i contract for live wake delivery.

Approving — eligible for operator merge once #12003 also lands for full AC8 path or eligible immediately if operator wants to merge incrementally.
