Resolves #12496
Related: #11605

Adds a durable Agent OS rollout-plan artifact that converts live `ai:skill-size-report -- --top 50` output into risk/size-ordered skill-compression batches. The plan keeps #12495 as the active pull-request pilot, ranks the next governance and lifecycle maps, and defines monitor-mode treatment for lower-pressure payloads.

Evidence: L1 (live inventory output + docs-tree registration + JSON/whitespace validation) -> L1 required (topology artifact derived from `ai:skill-size-report`). No residuals.

## Slot Rationale
- `learn/agentos/SkillCompressionRolloutPlan.md`: new Agent OS documentation page; disposition `keep` as a durable closeout artifact for #11605 AC6. Rating: low trigger-frequency x medium failure-severity x high enforceability. The page prevents repeated re-derivation from live size reports and gives future child tickets a stable ordering substrate; retirement trigger is #11605 closeout plus all listed batches either completed or explicitly retired.
- `learn/tree.json`: modified docs navigation only; disposition `keep -> keep`, making the new artifact discoverable.

Decision Record impact: `none`.

## Deltas from ticket
- Chose a `learn/agentos/` artifact instead of editing the #11605 epic body directly, so the plan can be reviewed and versioned with the codebase.
- Included the top 15 pressure rows from the live report and used top-50 output to define the lean / monitor threshold.

## Test Evidence
- `npm run ai:skill-size-report -- --top 50` passed; live snapshot: 90 files, 531238 bytes, 6370 lines.
- `node -e "JSON.parse(require('fs').readFileSync('learn/tree.json','utf8')); console.log('learn/tree.json OK')"` passed.
- `git diff --check origin/dev..HEAD` passed.
- Pre-push freshness check passed: `merge-base HEAD origin/dev == origin/dev`; outgoing branch history contains only `02905e6d9 docs(agentos): add skill compression rollout plan (#12496)`.

## Post-Merge Validation
- [ ] Link #11605 AC6 to `learn/agentos/SkillCompressionRolloutPlan.md` and re-run epic-resolution once #12495 also lands.

## Commit
- `02905e6d9` - `docs(agentos): add skill compression rollout plan (#12496)`

# 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.
