PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: Faithful, well-synthesized completion of #11605 AC6. It's topology-only (each compression stays a future child), live-derived, risk/size-ordered, and — the part that elevates it — it correctly integrates the rest of the cluster: sequences batches after the #12493 reference-integrity lint, maps Batch 0.1 to my claimed #12495 pilot, and guards against compressing away authority. Approve, not Approve+Follow-Up: the one nuance (keep-disposition rows in Batch 1) is already handled by Batch Rule 5.

Peer-Review Opening: As the author of #12496 + the #11605 re-triage, I checked this against the AC and the live inventory — it's accurate and the cross-cluster sequencing is exactly right. Strong synthesis.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #12496 (I authored it) + its Contract Ledger + AC, the changed files (SkillCompressionRolloutPlan.md, tree.json), the #11605 epic, my #12495 V-B-A (pull-request already extracted), and a live ai:skill-size-report run to cross-check the snapshot.
• Expected Solution Shape: a topology doc derived from LIVE inventory (not stale), risk/size-ordered batches, each mapping to a future sub/PR or noting status; must NOT hardcode a stale list (re-run mandate) and must register in tree.json (public-doc discipline); behaviour-preservation guard so future compressions don't drop load-bearing rules.
• Patch Verdict: Matches / improves. The snapshot table matches my live run row-for-row; Batch Rule 1 mandates re-running; batches 0/1 are ordered with next-actions; tree.json registered; Rule 5 is the authority-preservation guard. It exceeds the AC by sequencing against #12493 + #12495.

🔬 Depth Floor

Challenge: Batch 1 lists keep-disposition rows (e.g. 1.2 peer-role-mode.md) as compression targets. There's a real tension — the inventory tool says keep, the plan says "compress examples/provenance." The plan resolves it well (Rule 5: keep ≠ leave-forever; preserve high-severity common-path, compress only examples/provenance). The watch-item for executors: a keep row's compression PR must be more conservative (common-path is load-bearing), so each such batch child should re-confirm disposition before touching common-path prose. Non-blocking — the rule already states it; flagging so it survives into the child tickets.

Documented search — verified, no concern: (a) the snapshot matches a live ai:skill-size-report run exactly (not stale); (b) tree.json registers the public doc (per the nav-mirrors-folder discipline); (c) the cross-cluster sequencing (#12493 lint before mechanically-protected batches, #12495 before more pull-request tickets) is accurate.

Rhetorical-Drift Audit: Pass — "topology only", "live", and the cross-ticket sequencing claims all match the diff.

🧠 Graph Ingestion Notes

• [RETROSPECTIVE]: This closes the leanness epic's planning gap by making the remaining compression executable and sequenced — and notably it folds the session's friction→gold output (#12493 lint as the mechanical guard) into the rollout sequencing, so the batches are protected from the exact anchor-churn that motivated the lint. Good cross-cluster coherence.

🎯 Close-Target Audit

• Close-target #12496: confirmed enhancement/ai/model-experience/documentation — not epic. Pass.

📑 Contract Completeness Audit

• #12496 carries a Contract Ledger (the rollout-plan-doc row); the diff delivers exactly that (the doc + tree.json registration). Pass.

🔗 Cross-Skill / Public-Doc Audit

• learn/agentos/SkillCompressionRolloutPlan.md is registered in learn/tree.json (public-doc nav discipline). The doc references the skills + #12493/#12495 accurately. Pass.

N/A Audits — 📡 🧪

N/A: no openapi.yaml; docs-only change (no tests required per §2.2 — I cross-checked the inventory against a live ai:skill-size-report run instead).

📋 Required Actions

No required actions — eligible for human merge. (One non-blocking note above: carry the keep-row conservatism into each Batch-1 child ticket.)

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 94 — live-derived, integrates #12493/#12495 sequencing, tree.json-registered, authority-preservation guard.
• [CONTENT_COMPLETENESS]: 93 — all 3 ACs + batch rules + status mapping for active work; only the keep-row nuance left to the children.
• [EXECUTION_QUALITY]: 93 — snapshot matches the live run exactly; ordered batches; accurate cross-cluster references.
• [PRODUCTIVITY]: 90 — one focused artifact that unblocks the epic's resolution.
• [IMPACT]: 88 — turns the inventory into an executable, sequenced, lint-protected rollout; the topology the leanness epic was missing.
• [COMPLEXITY]: 50 — a planning/topology doc; the value is in the correct synthesis + sequencing, not mechanism.
• [EFFORT_PROFILE]: Quick Win — bounded planning artifact, high leverage (makes every downstream compression executable).

As #12496's author + the #11605 re-triager: accurate, live-derived, and the cross-cluster sequencing is exactly what I'd want. Approving. With this + #12495 (AC5) closed, #11605 resolves.
