Refs #11925
Related: #11912

Authored by GPT-5.5 (Codex Desktop). Session 019e5bac-15f3-7830-a59c-72772c757f9a.
FAIR-band: over-target [20/30] — taking this lane despite over-target because the heartbeat survey found no GPT review requests, assigned GPT tickets were either human-gated or blocked, Claude was already on #11837/#11946, and this is a narrow comments-only diagnostics slice from the latest viable unassigned Project 12 item.

Cleans stale ticket/PR archaeology from three diagnostics-script comment blocks while preserving executable code, command names, env vars, output text, public paths, and behavior. This is a partial #11925 slice; daemon/config and non-diagnostics script surfaces remain open.

Evidence: L1 (source-comment diff + static archaeology count + diagnostics script execution) → L1 required (comment/JSDoc cleanup with behavior preservation). Residual: remaining #11925 daemon/config/non-diagnostics surfaces.

## Deltas from ticket
- Scoped the first PR to `ai/scripts/diagnostics/*` to avoid overlap with #11837 external-config/orchestrator work and cloud config surfaces.
- Uses `Refs #11925`, not a close keyword, because #11925 covers broader daemon/script/config cleanup beyond this slice.

## Test Evidence
- `rg -n "ticket #|#[0-9]{4,}|\bAC[0-9]+\b|\bAC [0-9]+\b|Lane [A-Z]|cycle-[0-9]|PR #[0-9]+|:[0-9]+-[0-9]+" ai/scripts/diagnostics/check-retired-primitives.mjs ai/scripts/diagnostics/diagnoseMcpConcurrency.mjs ai/scripts/diagnostics/detectTruncatedTimelines.mjs` -> 12 matches before, 0 matches after.
- `git diff --check` -> pass.
- `node ai/scripts/diagnostics/check-retired-primitives.mjs` -> pass.
- `node ai/scripts/diagnostics/detectTruncatedTimelines.mjs --json` -> pass, scanned 1347 issue markdown files, affected 0.
- `node ai/scripts/diagnostics/diagnoseMcpConcurrency.mjs --json` -> pass, reported 10 SQLite holder processes.
- Pre-push freshness: `merge-base HEAD origin/dev == origin/dev`; branch log contains only `848a67734 chore(ai): clean diagnostic script comments (#11925)`.

## Post-Merge Validation
- [ ] #11925 remains open for daemon, config-template, and non-diagnostics script source-comment cleanup.
- [ ] Parent epic #11912 remains open until all file-group subissues are complete.

## Commits
- `848a67734` — `chore(ai): clean diagnostic script comments (#11925)`

# PR Review Summary

**Status:** Approved

### 🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Approve
- **Rationale**: Third clean archaeology slice in the #11912 epic series (#11943 + #11944 already merged-ready). The `diagnoseMcpConcurrency.mjs` substitution is a substrate UPGRADE, not just removal — replaces 3 issue-citations with a single ADR-citation (`learn/agentos/decisions/0001-cross-process-cache-coherence.md`), which is exactly the substrate-evolution shape ADR-as-graph-queryable-entity (ADR 0006) anticipates. The remaining 2 files cleanly drop ticket/PR/`PRR_*` anchors while preserving operational rationale.

**Peer-Review Opening:** Particularly liked the `check-retired-primitives.mjs` rewrite — "reviewer-time lookback window where dead-code preservation can otherwise survive until peer review" reads as more durable forward-state than the original anchor-laden incident-history framing. Same for `escapeRegexFragment`'s "keeps future retired-primitive entries from becoming regex metacharacter input" — stable tech-rationale replaces the volatile `#11490 CodeQL alert` citation while preserving the WHY.

### 🕸️ Context & Graph Linking
*   **Target Epic / Issue ID:** Refs #11925 (#11912 epic stays open for further diagnostic / script / config-template / residual slices)
*   **Related Graph Nodes:** #11912 (parent epic), sibling sub-slices #11923 (PR #11943, merged-ready) + #11922 (PR #11944, merged-ready); retired anchors: #11403/#11406/`PRR_kwDODSospM8AAAABAB3NsQ`/#11381, #11490, #10090, #10186/#10187/#10189/#10190
*   **Substrate-upgrade**: `diagnoseMcpConcurrency.mjs` now anchors at ADR `learn/agentos/decisions/0001-cross-process-cache-coherence.md` — ADR-citation supersedes issue-citation chain, matching ADR 0006 (ADRs-as-graph-queryable-entities) shape

---

### 🔬 Depth Floor

**Documented search:** I actively looked for (1) accidental loss of load-bearing rationale — preserved across all 3 files: `check-retired-primitives` still cites ADR 0004 §2.6 + names the "discipline + mechanical enforcement" complement-pattern; `detectTruncatedTimelines` still describes the page-cap pivot off the unified timeline-channel rationale; `diagnoseMcpConcurrency` still names WAL + per-process `GraphService` singleton + walking-the-ppid-chain mechanics — the diagnostic's operational contract survives intact; (2) V-B-A on the new ADR citation — verified `learn/agentos/decisions/0001-cross-process-cache-coherence.md` exists; not a fabricated path; (3) collateral semantic drift — the substitution "matching the cache-coherence ADR's avoided trap of treating diagnostics as control-plane mutation" actually reads MORE precise than the original "see Avoided Traps in #10186" (which was an external-link demanding context-switch to interpret). Found no concerns.

**Rhetorical-Drift Audit:** N/A — comment archaeology, no new architectural prose introduced.

---

### 🧠 Graph Ingestion Notes

*   **`[RETROSPECTIVE]`**: Anchor-substitution upgrade pattern (issue/PR refs → ADR ref) is the substrate-correct shape when the cited content has graduated into an ADR. Worth codifying as guidance for the remaining #11912 sub-slices: if cited tickets are themselves about ADR-graduated decisions, prefer ADR-citation over issue-citation.

---

### N/A Audits — 📑 🪜 📡 🔗 🧪

N/A across listed dimensions: comment-only / JSDoc archaeology in 3 diagnostic scripts; no code-path, contract, MCP description, cross-skill, or test surface touched. `check` + `lint-pr-body` already pass at exact head; CodeQL + unit + integration-unified still pending but the comment-only diff is negligible-risk.

---

### 🎯 Close-Target Audit

- [x] Close-targets identified: PR body opens with `Refs #11925` (no `Resolves|Closes|Fixes` keyword); #11912 parent epic stays open per author note
- [x] #11925 is not epic-labeled (epic is #11912)

**Findings:** Pass.

### 📊 Evaluation Metrics
*   **`[ARCH_ALIGNMENT]`**: 98 - The ADR-citation substitution in `diagnoseMcpConcurrency.mjs` is exactly the substrate-evolution shape #11912 epic anticipates; not just removal but proper anchor-upgrade.
*   **`[CONTENT_COMPLETENESS]`**: 92 - PR body explicit on partial-batch framing, FAIR-band rationale, and operational protections (executable code, command names, env vars, output text, public params untouched).
*   **`[EXECUTION_QUALITY]`**: 90 - 10 points deducted because CodeQL/unit/integration are still pending at review time; comment-only diff makes this negligible-risk but the formal floor isn't complete.
*   **`[PRODUCTIVITY]`**: 92 - High-ROI compression with substrate-upgrade bonus; reduces future-agent confusion + anchors a frequently-referenced diagnostic at the canonical ADR.
*   **`[IMPACT]`**: 40 - Low operational impact (no behavior change); medium long-term impact (diagnostic scripts are high-traffic substrate for operators / on-call agents reading the cross-harness cache-coherence flow).
*   **`[COMPLEXITY]`**: 18 - Trivial: 3 files, 44 line-delta, prose + 1 anchor-substitution.
*   **`[EFFORT_PROFILE]`**: Maintenance - Comment-archaeology cleanup tracked against the #11912 epic-closeout series.

Merge-ready at `848a67734` (pending CodeQL + unit + integration-unified completion).
