PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: Approve because the PR closes the contracted #12513 surface with exact-head CI green, focused local test/lint verification, and no blocking contract or reference-integrity drift. The only concern is a non-blocking audit note about explicitly documenting load-effect neutrality on future skill-map path-only updates.

Peer-Review Opening: Exact-head review of PR #12556. The implementation is targeted, mechanically guarded, and now rides on the #12557 lint semantics fix that removed the earlier false-positive blocker.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #12513 body/comments including its Contract Ledger, PR #12556 conversation, changed-file list, current dev source for lint-tree-json.mjs / moved AgentOS docs / workflow references, learn/agentos/process/reference-hygiene.md, turn-memory-pre-flight boundary, exact-head CI state, branch commit log.
• Expected Solution Shape: Correct shape is: relocate non-guide top-level AgentOS artifacts into non-published subfolders, update all live inbound references in the same PR, keep only intentionally-internal reference substrate top-level via explicit pure-data allowlist, and add a depth-1 NO_TOP_LEVEL_ORPHAN invariant with injectable filesystem probing. It should not hardcode broad basename heuristics or move the AGENTS.md atlas companion by accident; test isolation should keep lintTree() pure and cover registered, allowlisted, orphan, subfolder, and no-probe cases.
• Patch Verdict: Matches the expected shape. The diff contains eight 100% renames, live reference updates, a narrow allowlist for AGENTS_ATLAS / IdentitySchema / ModelStats / v13-path, and a unit-covered readDir probe in lintTree().

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

• Challenge: The PR necessarily changes .agents/skills/pull-request/SKILL.md, an always-loaded skill map. I verified this is a pure link-target correction in an existing one-line description plus manifest mirror, so it does not introduce new lifecycle behavior or a new loaded rule. Non-blocking follow-up discipline: future path-only skill-map updates should explicitly state /turn-memory-pre-flight = load-effect neutral/N/A in the PR body so reviewers do not have to infer it from the diff.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: framing matches what the diff substantiates. The NO_TOP_LEVEL_ORPHAN guard is accurately described as depth-1 only, with subfolders exempt.
• Anchor & Echo summaries: lint-tree-json.mjs summary and invariant text use precise mechanical terms; no over-broad public-guide claim.
• [RETROSPECTIVE] tag: none present.
• Linked anchors: #12511 / #12512 / #12497 / #12523 references match the dependency story.

Findings: Pass. I did find the old learn/agentos/evidence-ladder.md string in test/playwright/unit/ai/scripts/lint/lintSkillManifest.spec.mjs, but it is synthetic fixture data for the #12557 path-only diff behavior, not a live broken reference. Excluding that fixture, the stale moved-doc path sweep is clean.

🧠 Graph Ingestion Notes

• [KB_GAP]: N/A — the needed concepts were already present in #12513's Contract Ledger and the lint source.
• [TOOLING_GAP]: checkout_pull_request failed without a useful diagnostic when the local PR branch was stale/divergent. Manual detached checkout of origin/agent/12513-learn-orphan-cleanup restored exact-head reviewability.
• [RETROSPECTIVE]: This is the right complement to EXPLORATION_ARTIFACT: suffix-based nav hygiene catches published artifact names, while NO_TOP_LEVEL_ORPHAN catches any unregistered depth-1 AgentOS doc unless deliberately allowlisted.

🎯 Close-Target Audit

For every issue named as close-target, verify it does NOT carry the epic label:

• Close-targets identified: #12513 from the PR body; branch commit message contains ticket reference but no competing Closes / Fixes target.
• For #12513: confirmed labels are documentation, enhancement, ai; no epic label.

Findings: Pass.

📑 Contract Completeness Audit

• Originating ticket contains a Contract Ledger matrix.
• Implemented PR diff matches the Contract Ledger: process/ methodology docs, AGENTS_ATLAS kept top-level by allowlist disposition, invariant 7 added after #12523 sequencing, remaining orphan dispositions resolved by relocation or allowlist.

Findings: Pass.

🪜 Evidence Audit

• PR body contains an Evidence: declaration line: L2 ... → L2 required.
• Achieved evidence meets the required class: local focused unit test and static lints cover the close-target ACs.
• No residuals claimed or observed.
• No evidence-class collapse: review and PR scope stay static-lint/unit-test framed.

Findings: Pass.

📡 MCP-Tool-Description Budget Audit

Findings: N/A — no ai/mcp/server/*/openapi.yaml surface touched.

🔗 Cross-Skill Integration Audit

• Existing skills that referenced the moved docs were updated to learn/agentos/process/..., measurements/..., incidents/..., tooling/..., or wake-substrate/... as appropriate.
• skills.manifest.json mirrors the pull-request/SKILL.md description update.
• AGENTS_STARTUP.md is not implicated by this path-only relocation.
• No new MCP tool, wire format, or workflow convention introduced.
• Turn-memory load-effect audit: one skill-map description path changed, but no new rule/trigger/body was inserted; load-effect is neutral aside from the unavoidable corrected path target.

Findings: All checks pass — no integration gaps.

🧪 Test-Execution & Location Audit

• Branch checked out locally at exact detached head c67c3d2eeb969b483a3af7fc063bc4e9d0af5bc3.
• Canonical Location: the changed test remains in test/playwright/unit/ai/scripts/lint/lintTreeJson.spec.mjs, which is correct for AI-side lint script coverage.
• Ran the specific changed test file: npm run test-unit -- test/playwright/unit/ai/scripts/lint/lintTreeJson.spec.mjs → 22 passed.
• Ran related static evidence: npm run ai:lint-tree-json, npm run ai:lint-skill-manifest, npm run ai:lint-agents, and git diff --check origin/dev...HEAD all passed.
• Live GitHub checks are green at the same head, including unit, integration-unified, Tree JSON Lint, Skill Manifest Lint, PR-body lint, Retired Primitives, and CodeQL.

Findings: Tests pass.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 90 - 10 points deducted because the solution uses a maintained allowlist for intentionally-internal top-level docs; that is the correct boundary here, but it is still a manual future-touch surface rather than a self-discovering classification.
• [CONTENT_COMPLETENESS]: 90 - 10 points deducted because the PR body does not explicitly mark the path-only .agents/skills/pull-request/SKILL.md edit as /turn-memory-pre-flight load-effect neutral. The implementation and tests are complete; this is a documentation/audit clarity deduction only.
• [EXECUTION_QUALITY]: 100 - I actively considered stale moved-doc refs, fixture false positives, SEO drift, close-target validity, lint purity, and exact-head CI mismatch; all are either clean or intentionally bounded.
• [PRODUCTIVITY]: 100 - All #12513 ACs are delivered: relocations, allowlist disposition, remaining orphan cleanup, invariant 7, focused unit coverage, and relevant lints.
• [IMPACT]: 80 - 20 points below foundational because this is not core runtime architecture, but it materially improves public-learn hygiene and prevents repeat AgentOS orphan drift.
• [COMPLEXITY]: 55 - Medium: many path touchpoints and skill/docs references, but the code change is a narrow lint invariant with a pure injectable probe and focused tests.
• [EFFORT_PROFILE]: Quick Win - High ROI for moderate complexity: one PR converts a recurring docs-hygiene failure mode into a mechanical guard.
