Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: Correctly applies the #12514 de-publish decision with exact scope (removes only the 2 published leaves + their now-empty group), preserves the ref-protected cognitive-load-baseline, keeps all files on disk, and the SEO/nav contract is independently lint-verified. The other #12514 half (ConfigSubstrateEnvVarAudit) is genuinely already dispositioned by merged #12556, so Resolves #12514 is complete, not premature. Cross-family (Claude→GPT) → satisfies the merge gate.

Peer-Review Opening: Tight, correct residual cleanup — exact scope, files preserved, sequencing respected. Approving.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #12514 body + its T3 Contract Ledger (the 2-published-leaves + cognitive-load-ref-constraint + #12523 sequencing dep), the learn/tree.json AgentOS/Measurements group, the measurement files on disk, and the ConfigSubstrateEnvVarAudit location/nav status.
• Expected Solution Shape: Remove the 2 published tree.json leaves (pr-review-baseline-2026-04, heartbeat-token-economy-2026-05) + regen llms.txt/sitemap.xml; leave all files on disk; do NOT touch cognitive-load-baseline (live ADR 0008 + skill-guide refs); require #12523 already merged.
• Patch Verdict: Matches exactly. The tree.json diff removes precisely those 2 leaves + the emptied Measurements group; cognitive-load-baseline is untouched; all 5 measurement files remain on disk; SEO regenerated; #12523 is MERGED.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Resolves #12514
• Related Graph Nodes: #12556 (the top-level-orphan relocation that handled the ConfigSubstrateEnvVarAudit half — verified), #12523 (SEO_SYNC guard, merged), #12511/#12512 (parent).

🔬 Depth Floor

Challenge / documented search (§7.1): I checked whether de-publishing the two baselines from nav breaks any live reference. Found exactly 2 — .agents/skills/pr-review/references/measurement-methodology.md:29,35 — but both are file-path append-targets (the skill persists measurement data to learn/agentos/measurements/pr-review-baseline-2026-04.md). Since de-publish keeps the file on disk, these remain valid; nav removal is self-contained. Worth noting (non-blocking): that file is now nav-internal yet still an active append sink — consistent (it's a dated data log, not a public doc), but it means the file persists as live MX substrate, which is exactly the de-publish-not-delete intent.

Rhetorical-Drift Audit (§7.4):

• PR body "keeping the files on disk for internal/reference use" + "ADR/skill references … remain intact" — verified (files present; cognitive-load-baseline + the measurement-methodology append-target untouched).
• "already-merged top-level-orphan relocation lane handled that half" — verified: ConfigSubstrateEnvVarAudit.md now lives in measurements/ (relocated) with 0 tree.json nav refs.

Findings: Pass.

🧠 Graph Ingestion Notes

• [RETROSPECTIVE]: Model residual closeout — the #12514 decision split cleanly (Audit half via #12556 relocation, measurements half here), each scoped + the SEO_SYNC guard sequenced ahead. The de-publish-not-delete pattern correctly keeps dated MX baselines as internal substrate while removing them from the public nav (the original #12511 "raw baselines public by accident" bug).

N/A Audits — 📑 📡 🛂 🔗

N/A across listed dimensions: a learn-nav publish-status edit + generated-SEO sync — no public API/Contract surface, no OpenAPI, no new abstraction, no new cross-skill convention (Decision Record: None, correct — applies an existing publish-status decision).

🪜 Evidence Audit

• PR body declares Evidence: L1 (tree.json static nav edit + generated SEO output sync + tree lint) → L1 required (public learn publish-status / generated URL contract) — appropriate; the ACs are static nav/SEO contract, and L1 (static + lint) is the right ceiling. Independently re-ran ai:lint-tree-json → OK (195 nodes).

Findings: Pass.

🎯 Close-Target Audit

• Resolves #12514 (newline-isolated) — #12514 is a leaf (documentation/enhancement/ai, not epic).
• Completeness verified: both #12514 decisions are delivered — measurements de-publish (this PR) + ConfigSubstrateEnvVarAudit disposition (merged #12556, relocated to subfolder + de-nav'd). So the close is not premature.

Findings: Pass.

🧪 Test-Execution & Location Audit

• Checked out PR head (codex/12514-measurements-publish @ 484f41d4c).
• Ran npm run ai:lint-tree-json → [lint-tree-json] OK (195 nodes; tree mirrors learn structure + checked-in SEO outputs) — independently confirms the #12523 SEO-sync contract holds after the de-publish.
• Verified the measurement files remain on disk (ls learn/agentos/measurements/ → all 5 present) and no live ref dangles.

Findings: Pass — no runtime tests apply (nav/SEO doc change); SEO-sync guard independently verified.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 100 — Exact de-publish per the #12514 ledger: nav leaves removed, files kept, ref-protected file untouched, SEO regenerated, guard sequenced. I actively confirmed (a) scope ≠ over-broad (cognitive-load untouched), (b) no dangling refs, (c) the Audit half is genuinely done. None apply as gaps.
• [CONTENT_COMPLETENESS]: 95 — Fat-Ticket body with Evidence, the de-publish-vs-curate rationale, the #12556-handled-other-half note, Test Evidence, Post-Merge Validation. 5 deducted: doesn't explicitly note the surviving measurement-methodology.md append-target (a non-issue, but worth one line for the next reader).
• [EXECUTION_QUALITY]: 98 — Minimal, exact 3-file change; SEO outputs regenerated via the canonical generator; lint green (re-verified). 2 deducted: trivial — relies on the reader trusting #12556 for the other half (verified here).
• [PRODUCTIVITY]: 100 — Fully closes #12514's residual; both decisions now applied.
• [IMPACT]: 35 — Removes 2 raw dated baselines from the public portal nav (the #12511 "public by accident" class) while keeping them as internal MX substrate; bounded to publish-status.
• [COMPLEXITY]: 25 — Low: nav-leaf removal + generated-SEO sync; the only non-trivial part is honoring the cognitive-load ref-constraint + the #12523 sequencing, both satisfied.
• [EFFORT_PROFILE]: Quick Win — high-clarity small change closing a deferred decision.

Cross-family review (Claude→GPT) complete; ai:lint-tree-json re-verified; scope + completeness + ref-safety V-B-A'd; approving for human merge. Clean residual close. 🖖
