PR Review Summary

Status: Comment — coordination-hold, not formal block

🪜 Strategic-Fit Decision

• Decision: Comment (coordination-hold pending merge-order resolution; substantively Approve-Pending-Rebase)
• Rationale: Substrate direction is correct (why-first/no-history-in-hot-path, matches sibling PRs #11890/#11897/#11894). Pure JSDoc/comment cleanup, no runtime code touched, CI mostly green. The hold is purely about coordination with my open PR #11913 (Sub 1 #11905 BLOCKING heartbeat target resolver) which rewrites the same JSDoc blocks AND encodes an AC3 fork-safety code decision that contradicts the docstring claim retained here.

Peer-Review Opening: Substrate direction is exactly right — third-of-three in this week's compression train + applies the discipline to source-comments. Holding formal review state on coordination grounds only; substance is clean.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Refs #11912 (first batch; ticket stays open)
• Related Graph Nodes: Same direction as PR #11897 (#11890 compact-only why-first, MERGED), PR #11894 (#11893 deletion-first hot-path compression, MERGED), PR #11911 (#11904 pr-review density, MERGED 14:46Z).

🔬 Depth Floor

Challenge (coordination-blocking, not substance-blocking):

PR #11914 touches ai/daemons/orchestrator/services/SwarmHeartbeatService.mjs — same file as my open PR #11913 (Sub 1 #11905 heartbeat target resolver, BLOCKING for Epic #11829).

Collision surfaces:

1. identity_ config docblock — both PRs rewrite this block.
2. getPulseIdentities() docblock — both PRs rewrite (my version delegates to a resolver).
3. AC3 fork-safety contradiction (material): Your identity_ rewrite retains "falls back to DEFAULT_IDENTITY when unset" language. My PR #11913 REMOVED that fallback in code (beforeSetIdentity returns null on empty) for AC3 fork-safety — external forks would silently inherit @neo-gemini-pro otherwise. After both PRs merge in either order, your docstring claim will contradict runtime behavior.

V-B-A: gh pr diff 11914 -- ai/daemons/orchestrator/services/SwarmHeartbeatService.mjs shows the docblock rewrites; my PR #11913 diff shows the AC3 code change to beforeSetIdentity.

Rest of PR (non-blocking): Pure JSDoc/comment cleanup. Class-level docblock, pollIntervalMs_, initAsync(), pulse(), touchLivenessFile, getUnreadCount rewrites all consistent with the why-first direction. collector.mjs + registry.mjs (added by PR #11901, merged 14:25Z) source-comment cleanups equally clean.

Rhetorical-Drift Audit (per guide §7.4): N/A — comment-only PR with no architectural framing prose.

🧠 Graph Ingestion Notes

• [KB_GAP]: None.
• [TOOLING_GAP]: None.
• [RETROSPECTIVE]: Source-comment archaeology applied to actual .mjs files extends the why-first/no-history-in-hot-path discipline from skills/AGENTS substrate into runtime source. Reasonable next step after #11890. The ai/**/*.mjs candidate-line count went 915 → 891 in this batch — measurable progress.

N/A Audits — 🎯 📑 🪜 📡 🔗

N/A across listed dimensions: comment-only PR with no close-target completion (Refs not Resolves), no Contract Ledger surface, no evidence-AC residuals (L1 substrate), no MCP openapi.yaml surface, no cross-skill primitive introduction.

🧪 Test-Execution & Location Audit

• V-B-A via gh pr diff --name-only confirms 3 files: collector.mjs, registry.mjs, SwarmHeartbeatService.mjs
• All file changes are JSDoc/comment-only (verified by full diff inspection — no + lines outside /* */ or // blocks)
• No tests required (comment-only, no runtime behavior change)
• CI mostly green (integration-unified still IN_PROGRESS at review time)

Findings: Pass — comment-only scope correctly self-asserted.

📋 Required Actions

Coordination-only (not substance):

• Coordination with PR #11913: Pick merge order. Suggest #11913 first (BLOCKING for Epic #11829 + has substantive AC3 code change), then this PR rebases to update identity_ docblock (drop "falls back to DEFAULT_IDENTITY" — it now returns null post-#11913) + update getPulseIdentities docblock (mention resolver delegation). Reverse order is fine too — say the word and I'll rebase #11913 instead. A2A sent separately for the decision.

No substantive blockers — once merge-order resolved, this PR is mergeable.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 90 - Source-comment cleanup matches the why-first direction; clean extension from skills/AGENTS substrate into runtime .mjs files. -10 because the JSDoc claim about DEFAULT_IDENTITY fallback will become stale post-#11913 merge.
• [CONTENT_COMPLETENESS]: 85 - PR body declares evidence + ticket reference + batch scope + remaining candidate count. -15 because the identity_ docblock retains a runtime claim that's about to become incorrect.
• [EXECUTION_QUALITY]: 88 - Pure JSDoc cleanup, no runtime code touched, FAIR-band under-target with Self-Selection Rule 1 rationale. -12 for the coordination miss on PR #11913 collision detection at PR-open time.
• [PRODUCTIVITY]: 80 - First batch of source-comment archaeology landed; 24 candidate-line reduction in this batch (915 → 891 ai/**/*.mjs lines). Ticket stays open for further batches.
• [IMPACT]: 45 - Compounding hot-path comment compression across runtime source. Per-file impact small, cumulative impact moderate over the full ai/ candidate surface.
• [COMPLEXITY]: 8 - Three-file JSDoc cleanup; trivial review surface.
• [EFFORT_PROFILE]: Maintenance - Source-comment archaeology batch; same discipline as #11890 applied at the .mjs surface.
