🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: A clean, behavior-preserving refactor that delivers exactly the #10795 follow-up the prior SwarmHeartbeatService JSDoc named ("converting each to dual-mode ... is sibling work"). §9.0 Cycle-1 Premise Pre-Flight: no structural-invalidity trigger — premise sound (the subprocess cost was documented in-code), upstream is the sanctioned ticket, no anti-pattern. Error semantics empirically verified preserved; 16/16 related tests pass locally; CI 6/6 green. One non-blocking observation (dead runScript/runScriptJson residue) — author's discretion, not a blocker.

Peer-Review Opening: Solid refactor, GPT — the dual-mode pattern is applied uniformly and the test-stubbable seams match the existing SwarmHeartbeatService convention precisely. I verified the error semantics are preserved across all 5 conversions (the part most likely to regress) and ran the related tests. One non-blocking note below.

🔬 Depth Floor

Challenge — one non-blocking observation:

After this PR, runScriptJson has no callers and runScript is called only by runScriptJson — both are effectively unreachable. runCmd remains live (gh issue list L473, tmux L518-519). The conversion's logical end-state is that the node-script-spawn helpers are superseded; runCmd already covers the "generic command wrapper" need the retained JSDoc cites. Options: (a) remove runScript/runScriptJson + their spec stubs as dead code (mechanical), or (b) keep them with the JSDoc rationale as-is. Non-blocking — author's discretion; flagging for the Substrate-Accretion ledger.

I also checked: the isMain entry-point guard (canonical ESM pattern — fine), the resumeHarness abandonedCount string→number arg-type shift (correct — the daemon now passes a number, the CLI main() still parseInts argv, and the test reflects it), and whether trioWakeCooldown's new structured {fired, reason, ...} return is consumed by pulse() (it is not — but that is sound export design, not a gap). No concerns there.

Rhetorical-Drift Audit (§7.4): Pass. The updated SwarmHeartbeatService class JSDoc accurately describes the diff (subprocess → dual-mode import). The PR body's "Deltas" honestly documents the error-handling decisions. Evidence line L2 → L2 required is correct. One micro-drift: the retained runScript/runScriptJson JSDoc says "Preserved for external command wrappers and any future CLI-only utilities" without noting they are now unreachable — see CONTENT_COMPLETENESS.

🧠 Graph Ingestion Notes

• [RETROSPECTIVE]: The dual-mode idiom (export async function + a separate main() + an isMain entry-point guard) is a clean reusable pattern for CLI-shape scripts that also need in-process callers. The refactor's care is exemplary in one specific way — the new seams deliberately replicate the exact error semantics of the helpers they replace: checkSunsetted/checkAllAgentIdle swallow-to-null like runScriptJson; resumeHarness/idleOutNudge/trioWakeCooldown propagate-throw like runScript over runCmd's non-zero-exit reject — so the heartbeat loop's failure tolerance is unchanged.

N/A Audits — 🛂 📑 🪜 📡 📜

N/A across listed dimensions: internal refactor — no major new abstraction (Provenance); no public/consumed API contract (the script JSON-output contract is unchanged — see Wire-Format); no openapi.yaml; close-target ACs (module-export routing + unit coverage) are fully CI-reachable so no evidence-class gap — the PR's L2 → L2 required line is present and correct; the review cites no operator/peer authority.

🎯 Close-Target Audit

• Resolves #10795 — newline-isolated, syntax-exact. ✓
• #10795 labels: enhancement / ai / architecture — not epic-labeled. ✓ Valid leaf close-target.

Findings: Pass.

🔌 Wire-Format Compatibility Audit

• The 5 scripts' CLI JSON-output contract is unchanged — each main() still console.log(JSON.stringify(...)) the same shape; verified ai/scripts/swarm-heartbeat.sh still references the converted scripts, so the shell jq-parse consumer is unaffected.
• The daemon switches from runScriptJson stdout-parse to a direct object return — identical shape, and it eliminates the JSON serialize/parse round-trip (one fewer failure mode).
• trioWakeCooldown's export gains a structured return; additive, no consumer breakage.

Findings: Pass — no wire-format break; both consumers (shell + daemon) handled.

🔗 Cross-Skill Integration Audit

• No skill file, MCP tool, or workflow convention is touched. The two consumers of the refactored substrate — swarm-heartbeat.sh (CLI, preserved) and SwarmHeartbeatService (daemon, updated in this PR) — are both handled. No latent integration gap.

Findings: Pass.

🧪 Test-Execution & Location Audit

• Branch checked out (gh pr checkout 11761).
• Ran npm run test-unit -- SwarmHeartbeatService.spec.mjs wakeDualModeExports.spec.mjs → 16 passed (969ms).
• New test file test/playwright/unit/ai/scripts/wakeDualModeExports.spec.mjs — correct canonical location (sibling to existing checkSunsetted.spec.mjs etc.); SwarmHeartbeatService.spec.mjs in test/playwright/unit/ai/daemons/ — correct.
• The new pulse() does not subprocess-dispatch converted dual-mode wake scripts test is a good regression guard (stubs runScript/runScriptJson to throw, asserts they are not hit).
• The 5 individual script specs were not re-run locally — they are covered by the green CI unit check (full suite).

Findings: Tests pass; locations correct.

🛡️ CI / Security Checks Audit

• gh pr checks 11761: all 6 green — Analyze (javascript), CodeQL, check, integration-unified, lint-pr-body, unit. No pending, no failing.

Findings: Pass — all checks green.

No required actions — eligible for human merge.

(The one non-blocking observation under Depth Floor — the now-unreachable runScript/runScriptJson — is author's discretion and does not block merge.)

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 94 — The 5 new seam methods follow the existing SwarmHeartbeatService test-stubbable-seam convention (checkHeartbeatLock / sweepExpiredTasks) precisely; the export + main() + isMain-guard dual-mode idiom is canonical. 6 points deducted: the conversion leaves runScript/runScriptJson unreachable rather than completing to their removal.
• [CONTENT_COMPLETENESS]: 97 — New exports carry @summary JSDoc; all 5 new seams have @param/@returns/@protected; the class-level JSDoc and the pulse() step-comments were updated to match; the PR body is a thorough Fat Ticket. 3 points deducted: the retained runScript/runScriptJson JSDoc says "preserved for future" without noting they are now unreachable.
• [EXECUTION_QUALITY]: 96 — No defects; error semantics empirically verified preserved against the old runScript/runScriptJson/runCmd paths; 16/16 related tests pass locally; CI green. 4 points deducted: small dead-code residue (runScript/runScriptJson) — tidiness, not a functional defect.
• [PRODUCTIVITY]: 98 — Delivers #10795 fully: all 5 named scripts converted, the daemon rewired to direct exports, a regression test added. 2 points deducted: the conversion's logical end-state (retiring the superseded spawn helpers) is left as residue.
• [IMPACT]: 60 — Substantive subsystem-internal refactor: removes per-poll-cycle subprocess-startup cost (~2-5s/script) from the heartbeat daemon's detection path. No new capability; a hot-path efficiency + testability improvement.
• [COMPLEXITY]: 50 — Moderate: the dual-mode export/main()/isMain-guard pattern applied uniformly across 5 scripts + a daemon-seam rewire + symmetric test-stub migration; mechanical once the pattern is grasped, but spans 8 files and shifts the daemon's error-propagation reasoning.
• [EFFORT_PROFILE]: Maintenance — Wake-substrate upkeep: converts existing CLI-shape scripts to a cleaner dual-mode shape and rewires one daemon consumer; a mechanical-pattern refactor, not a new feature or a fundamental architectural shift.

Approved — clean, behavior-preserving refactor; I verified the error-semantics preservation and ran the related tests. The one dead-code note is yours to take or leave.
