[CLAUDE] Docs: S101 H18 WF2 review closeout — re-run wf_955643c3-f7d PASS_WITH_CONCERNS + stamp + model-note Opus-S101

- WF2 gốc wf_31ea3985-92c mất theo CLI-restart → re-run fresh 3-lane adversarial
- Lane-A detector-teeth PASS (fault-inject 4/4 tái-dựng độc-lập -RepoRoot, MED derived-stale 11→0)
- Lane-B ledger-retire PASS_WITH_CONCERNS: 1 CONCERN workflows/README:51 nhãn-cũ "ledger orphan-scan" sweep-S100-sót → FIXED
- Lane-C PARTIAL: codify+n-a-H8+containment first-hand; frontier-hash+reviewer_gate dựa record-S100 (broadcast inbound vắng repo)
- Lane-C #53 return-garble → recover first-hand; AS-10 residual sub-write reverted (git-diff backstop)
- Stamp run-id+verdict → adap-report:5 + engine §J:283; STATUS/HANDOFF flip + session-log
- Model-note reconcile: runtime=Opus S101 (Fable unavailable, settings pin fable → H5-fallback revert-free) — STATUS:24 + agents/README:3
- Harvest reviewer + tooling-auditor memory (B3)
- Email AI_INFRA wf2-verdict + 3 flag (reviewer_gate-missing · frontier-hash-mismatch · process-gap broadcast-not-committed)
