🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: Pure comment/JSDoc cleanup with mechanical preservation of runtime behavior. The diff strips ticket/AC/phase archaeology (#11417, #11029, #10148, #10257, #10347, #10178, #10180, #10184, #10181, #11642, #11528, #10338, #10339, #10313) from JSDoc while preserving the durable contracts each comment was conveying. Net -24 lines (111 insertions / 135 deletions). Aligns with #11912 epic's stated goal under #11922 grouped sub-issue. No code semantics changed.

Peer-Review Opening: Thanks for taking the heaviest-noise Memory Core file as the first batch — MailboxService had 60 archaeology matches and you got it down to 1 (the residual being the runtime warning-string payload, which is correctly preserved). Clean execution of the #11912 epic shape against #11922 leaf.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Related: #11912 (epic), Refs #11922 (grouped Memory Core sub) — neither closed by this PR.
• Related Graph Nodes: MailboxService, A2A protocol envelope (#10338 task state-machine, #11029 broadcast delivery edges, #10148 archive/retract, #10257 syncCache+vicinity, #11417 mailbox target validation, #10347 SENT_TO edge cull observability). All archaeology references stripped from JSDoc; their durable semantics remain in the local-contract comment shape.

🔬 Depth Floor

Challenge: The Phase 1 #10347 Observability comment was simplified to Make SENT_TO edge-creation failures loud and cross-process readable. The runtime warning string "[#10347 Phase 1] Intermittent SENT_TO edge cull detected" (line 497 of the post-PR file) is correctly preserved because it's part of the observable log payload that downstream parsers/dashboards may grep for — that's the false positive on the regex sweep. One concern worth flagging: the surrounding diagnostic comment removed Phase 1 #10347 context entirely, but the WARNING STRING ITSELF still carries that ticket reference. If a future archaeology sweep regexes only the runtime payload (without the now-stripped JSDoc context), it might mistakenly conclude the string is also archaeology and propose its removal — which WOULD be a behavior change. Not a blocker for this PR, but worth a Note: log-payload string preserved intentionally — observable surface inline comment near line 497 to prevent future drift. Non-blocking polish; deferrable to follow-up.

Rhetorical-Drift Audit:

• PR description: framing matches the diff (comment-only; non-closing epic reference correctly uses Related: + Refs; Contract Ledger documents the runtime-string preservation)
• Anchor & Echo summaries: JSDoc retains precise codebase terminology (e.g., SENT_TO, DELIVERED_TO, PART_OF_THREAD, IN_REPLY_TO, addEdges + acknowledgeLocalMutations, WAL coherence) without metaphor or ticket archaeology
• [RETROSPECTIVE] tag: N/A — none added
• Linked anchors: PR body cites #11912 epic + #11922 grouped sub correctly; no borrowed authority

Findings: Pass with one Note flagged as non-blocking polish concern (see Required Actions).

🧠 Graph Ingestion Notes

• [KB_GAP]: N/A.
• [TOOLING_GAP]: N/A — the rg --count-matches diagnostic + manual diff scan is sufficient tooling for archaeology sweeps at this scope.
• [RETROSPECTIVE]: Demonstrates the right shape for #11912 epic batches: grep against the canonical archaeology regex, sweep the highest-density file first (MailboxService = 60 hits), preserve runtime log payloads as documented false-positives, file Refs not Closes against the epic. Other Memory Core files (MemoryService, GraphService, DatabaseService) can follow this exact template.

🎯 Close-Target Audit

• Close-targets identified: none via magic keywords. Related: #11912 + Refs #11922 are both non-closing references (correct per the Epic Close-Target Ban — #11912 is the epic, #11922 the grouped sub).
• No Closes #N / Resolves #N / Fixes #N in PR body or commit message.

Findings: Pass.

📑 Contract Completeness Audit

• Originating ticket contains a Contract Ledger matrix — the PR body itself has a Contract Ledger documenting the two surfaces touched (JSDoc archaeology removal + runtime warning string preservation). #11922 is a grouped sub of #11912 and inherits the epic's contract semantics; comment-only PRs do not require a separate ticket-side ledger.
• Implemented PR diff matches the Contract Ledger exactly — no drift; the diagnostic count (60 → 1) is empirically reproduced via the documented commands.

Findings: Pass.

N/A Audits — 🪜 📡 🔗 🧪

N/A across listed dimensions: comment/JSDoc-only PR with no runtime code change → Evidence Audit not applicable (no executable behavior shipped); no ai/mcp/server/*/openapi.yaml touched → MCP-Tool-Description Budget Audit N/A; no skill/AGENTS/convention files touched → Cross-Skill Integration Audit N/A; per pr-review-guide §2.2 "If it is a documentation/template change, running tests is not required" → Test-Execution Audit N/A.

📋 Required Actions

To proceed with merging, please address the following:

• (Polish, non-blocking) Add an inline comment near MailboxService.mjs:497 noting that the runtime warning string "[#10347 Phase 1] Intermittent SENT_TO edge cull detected" is preserved as an observable log payload. This prevents a future archaeology sweep from misclassifying the string as removable JSDoc artifact. Suggested inline comment: // [#10347] in log payload is observable surface — DO NOT strip in future archaeology sweeps. Defer to follow-up if you'd prefer to bundle with the next #11912 batch.

This is a polish nit; APPROVED state stands. Merge eligibility is not blocked on this item — it's a safety rail against future drift.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 100 — No architectural shift. Comment-only cleanup that preserves all durable Memory Core mailbox contracts (SENT_BY/SENT_TO/DELIVERED_TO/PART_OF_THREAD/IN_REPLY_TO/A2A-Task-envelope semantics) verbatim. Considered alternatives: (a) bundling ticket-references-as-graph-edges retention check, (b) moving any preserved-archaeology to a separate learn/agentos/ document, (c) auto-generating cross-link from durable comments to graph nodes — none apply because the epic's stated shape is mechanical-archaeology-removal, not substrate-evolution.
• [CONTENT_COMPLETENESS]: 95 — Anchor & Echo JSDoc preserved with substantive content for every public method. 5 points deducted because the runtime warning string at line 497 lacks an inline anchor noting its observable-surface status (see Required Actions). Otherwise complete.
• [EXECUTION_QUALITY]: 100 — Tests not required per guide §2.2; mechanical comment-only diff cannot regress runtime. Diagnostic count (60 → 1) reproducibly documented. git diff --check origin/dev...HEAD clean per PR body. Considered: (a) hidden semantic shift via JSDoc parameter rename, (b) accidental deletion of code lines disguised as comments, (c) introduced trailing whitespace — none apply.
• [PRODUCTIVITY]: 100 — All stated PR-body goals achieved: MailboxService archaeology cleared, runtime preserved, non-closing references on epic+sub, Contract Ledger present. Considered: incomplete sweep — not the case (60 → 1, residual documented).
• [IMPACT]: 30 — Routine maintenance against a hot-path subsystem. Reduces cognitive-load for future readers + future archaeology sweeps but does not change framework behavior or extend capability.
• [COMPLEXITY]: 20 — Low: single-file, mechanical, scope-tight. No new abstraction; no cross-substrate dependency; one residual documented. Cognitive load to validate is bounded by the diff length (530 lines) and the archaeology regex.
• [EFFORT_PROFILE]: Maintenance — Routine archaeology sweep against the highest-density Memory Core file. Sets the template for sibling Memory Core files (MemoryService, GraphService, DatabaseService) under the #11912 epic. Not a Quick Win because impact is invisible to runtime; not a Heavy Lift because complexity is bounded.

Clean PR; the polish nit on line 497 is the only durable concern. APPROVED — eligible for human merge.
