🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: Live computation supersedes static doc — exactly the right shape after operator step-back rejected the static-inventory approach (PR #11903 dropped). Clean extension of existing lint-skill-manifest.mjs with --report-sizes + --top N modes; no new file, no new architectural primitive, no Contract Ledger surface introduced. 25 unit tests pass. PR body explicitly acknowledges disposition labels as "candidate hints, not permanent architecture truth" — sidesteps the threshold-magic-number trap.

Peer-Review Opening: Right substrate shape after the operator step-back. Static-inventory drift is exactly what shipped tools are supposed to obviate; landing this in lint-skill-manifest keeps the tooling boundary clean. Approved.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Resolves #11902
• Related Graph Nodes: PR #11903 dropped (static doc rejected by operator step-back); #11605 referenced for downstream cleanup planning; sibling to PR #11894 / #11897 / #11911 compression-train direction.

🔬 Depth Floor

Challenge (non-blocking):

The countMatches provenance regex in skillMarkdownSizeReport() — /archaeolog|provenance|incident|origin|lineage|empirical anchor/ig — matches origin very broadly. origin/dev, originSessionId, originating ticket, etc. all match. This will inflate the provenance count on skill prose that legitimately references git remotes or session ID fields, which then weights into signals (×2), which then influences compress-to-trigger disposition (>150 signals).

Two pragmatic reasons not to block on this:

1. The PR body explicitly tags disposition labels as "candidate hints for follow-up planning, not as permanent architecture truth" — the tool is operator-judgment-supporting, not operator-judgment-replacing.
2. Live measurement makes calibration cheap — run the report, inspect actual rankings, adjust the regex narrower if a specific file's score is implausible. Static-doc would have baked any over-broad heuristic in indefinitely.

Future-work candidate: tag origin with stricter word-boundary (e.g. \borigin(?:al|ate|ating)?\b to exclude origin/dev and originSessionId). Tagging as hypothesis — needs V-B-A before implementation per pr-review-guide §7.4 — defer rather than plant unverified-as-prescribed.

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

🧠 Graph Ingestion Notes

• [KB_GAP]: None.
• [TOOLING_GAP]: None.
• [RETROSPECTIVE]: Operator step-back on PR #11903 (static doc) → supersede with live computation (this PR) → exact pattern feedback_distributed_artifacts_invert_local_fs.md + feedback_llm_substrate_for_semantic_tasks.md warn against. Shipped tools that compute on demand stay accurate; committed snapshots drift after a few PRs. Reinforces the discipline: avoid committing computed values that have a cheap live-recompute path.

🎯 Close-Target Audit

• Close-targets identified: #11902
• For each #N: confirmed not epic-labeled (#11902 is the sub-ticket under #11605 cleanup work, not the epic)

Findings: Pass.

🪜 Evidence Audit

• PR body contains an Evidence: declaration line: Evidence: L1 (CLI report mode + focused unit coverage + manifest lint) -> L1 required (tooling behavior and reproducible measurement ACs). No residuals.
• Achieved evidence ≥ close-target required evidence (L1=L1 for tooling-behavior-only change)
• No residuals declared and none surfaced by V-B-A

Findings: Pass.

N/A Audits — 📑 📡 🔗

N/A across listed dimensions: tooling extension with no Contract Ledger surface, no MCP openapi.yaml surface, no cross-skill primitive introduction (extends existing lint-skill-manifest binary, adds convenience npm alias).

🧪 Test-Execution & Location Audit

• V-B-A via gh pr diff --name-only confirmed 3 files: lint-skill-manifest.mjs, package.json, lintSkillManifest.spec.mjs
• Canonical Location: test/playwright/unit/ai/scripts/lint/lintSkillManifest.spec.mjs is the existing test location
• PR body declares npm run test-unit -- test/playwright/unit/ai/scripts/lint/lintSkillManifest.spec.mjs -> 25 passed
• CI checks all SUCCESS at review time (lint-pr-body, Analyze javascript, check, lint, check-size, integration-unified, unit, CodeQL)

Findings: Pass.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 92 - Live-computation-replaces-static-doc is exactly the right substrate shape after the operator step-back on PR #11903. Extends existing tooling cleanly; no new architectural primitive.
• [CONTENT_COMPLETENESS]: 88 - PR body declares evidence + scope + supersede rationale + npm alias intent + post-merge validation. -12 for the regex over-match concern (origin → origin/dev) noted in Depth Floor — non-blocking but worth a follow-up tag.
• [EXECUTION_QUALITY]: 92 - 25 unit tests pass; whitespace clean; CI fully green; pre-push freshness check confirmed in PR body.
• [PRODUCTIVITY]: 88 - Supersede-after-drop is a clean substrate-evolution recovery; tooling is reusable across future skill-size measurement needs (#11605 follow-up children).
• [IMPACT]: 65 - Tooling-substrate impact; modest per-invocation but compounds as the skill substrate grows + as #11605 cleanup children consume the live report.
• [COMPLEXITY]: 28 - +184 / -2 LOC, single-file core (lint-skill-manifest.mjs); pure-function helpers + 1 new top-level mode; trivial review surface relative to LOC.
• [EFFORT_PROFILE]: Polish - Substrate-evolution recovery after operator step-back; ships measurement tooling with no runtime substrate change.
