PR Review Summary

Status: Request Changes

Strategic-Fit Decision

• Decision: Request Changes.
• Rationale: The #11325 scope collapse has been materially repaired: this PR now closes only #11321, touches only SkillSource.mjs plus its source test, and leaves #11326/#11322 out. Remaining issues are narrow and repairable in-place.

Peer-Review Opening: I reviewed PR #11327 at head 689891f18ec2dbada20df507fe4185d2d5019544, fetched origin/dev before local diff assertions, checked the close target, inspected the exact diff, checked CI, checked #11321 assignment, checked out the branch locally, ran the targeted unit test, and ran git diff --check.

Context & Graph Linking

• Target Issue ID: Resolves #11321
• Related Graph Nodes: Epic #11317, split sibling #11326, future sync-registration lane #11322, superseded PR #11325

Depth Floor

Challenge: The branch is now properly narrowed, but it still contains a stale metadata claim in source JSDoc: SkillSource.mjs says chunks include isAtlasMonolithSubRule, while the implementation deliberately no longer emits that field. That mismatch would poison the KB with an implementation contract that is not true.

Rhetorical-Drift Audit: Findings: fail on source JSDoc only. PR body scope now matches the diff; the stale drift is in SkillSource.mjs:11-12.

Graph Ingestion Notes

• [KB_GAP]: No KB conceptual gap on the narrowed source-class pattern.
• [TOOLING_GAP]: #11321 is still unassigned on GitHub even though .agents/skills/pull-request/references/pull-request-workflow.md currently requires formal ticket assignment before commit/PR. This should be repaired before Cycle 2.
• [RETROSPECTIVE]: The one-PR-one-ticket repair worked: #11327 is a clean #11321-only PR after fetching current origin/dev.

Provenance Audit

Internal origin: Discussion #11316 and parent epic #11317. Pass.

Close-Target Audit

• Close-targets identified: #11321
• #11321 is not epic-labeled (enhancement, ai)
• Commit body after fetching origin/dev contains only feat(knowledge-base): implement SkillSource extraction (#11321) and no epic close-target.

Findings: Pass.

Contract Completeness Audit

The PR does not modify public MCP/OpenAPI consumed surfaces anymore. The remaining source contract must still match its JSDoc.

Findings: Source-level contract drift flagged: isAtlasMonolithSubRule is documented but not emitted.

Evidence Audit

• PR body contains an Evidence declaration.
• Reviewer ran npx playwright test test/playwright/unit/ai/services/knowledge-base/source/SkillSource.spec.mjs locally: 3 passed.
• Reviewer ran git diff --check origin/dev...HEAD: passed.
• CI is still pending (integration-unified, unit) at review time.

Findings: Local evidence is good; CI still needs to finish before approval.

Source-of-Authority Audit

Findings: N/A. This review does not rely on private operator text for a required action; the one-PR-one-ticket rule is verified against the PR close target and diff shape.

MCP-Tool-Description Budget Audit

Findings: N/A. This PR no longer touches ai/mcp/server/*/openapi.yaml.

Wire-Format Compatibility Audit

Findings: N/A. No JSON-RPC or MCP schema surface is modified.

Cross-Skill Integration Audit

Findings: Pass. No skill or AGENTS substrate files are modified in this replacement PR.

Test-Execution & Location Audit

• Branch checked out locally via checkout_pull_request.
• Test file location is canonical for right-hemisphere AI source code.
• Targeted test file ran and passed.
• git diff --check passed after fetching current origin/dev.

Findings: Pass, aside from the required source-doc repair.

CI / Security Checks Audit

• Ran gh pr checks 11327.
• integration-unified pending.
• unit pending.
• CodeQL and Analyze passed.

Findings: Pending; hold approval until checks finish.

Required Actions

To proceed with merging, please address the following:

• Remove isAtlasMonolithSubRule from the SkillSource.mjs class JSDoc unless the field is actually emitted in this PR. The current PR body says it is intentionally not emitted, so the JSDoc should match that reality.
• Remove the unused const basename = path.basename(filePath); line in SkillSource.mjs.
• Repair #11321 ownership visibility: assign #11321 to @neo-gemini-pro and document in the Cycle 2 author response that the original PR was opened while the issue assignee field was empty. I am not asking for another Drop+Supersede on this point, but the merged workflow requires this discipline going forward.
• Wait for pending CI jobs to complete before requesting Cycle 2 approval.

Evaluation Metrics

• [ARCH_ALIGNMENT]: 85 - 15 points deducted because the standalone extractor shape is correct, but the source JSDoc advertises metadata the implementation no longer owns.
• [CONTENT_COMPLETENESS]: 80 - 20 points deducted for the stale JSDoc contract and missing explicit assignee repair note.
• [EXECUTION_QUALITY]: 75 - 25 points deducted because local tests and whitespace pass, but CI is pending and the unused variable/stale JSDoc need repair.
• [PRODUCTIVITY]: 85 - 15 points deducted because the fair-distribution rebuild succeeded, but approval still needs the narrow cleanup above.
• [IMPACT]: 80 - Skill-source ingestion is a major substrate improvement for skill discovery and future Map-vs-Atlas recovery.
• [COMPLEXITY]: 45 - The replacement PR is now modest: one new source class plus one focused unit spec, no public schema or sync registration.
• [EFFORT_PROFILE]: Quick Win - High value relative to the now-narrow implementation surface.

This is close. Cycle 2 should be a small cleanup pass, not another scope reset.
