R11 (David, fresh-eyes stability check): 0 Critical + 0 High + 1 Medium (doc cleanup from R10-F-2 closure itself). R11-M-1 (MEDIUM): CUTOVER_QA.md + vault-cli/README.md still referenced --canary-percent flag after R10-F-2 removed it from code + ARCHITECTURE.md. Operator following CUTOVER_QA.md step 1 of cutover day would hit 'Error: no such option --canary-percent' \u2014 the one document whose entire purpose is cutover correctness. Fix: CUTOVER_QA.md \u00a71 replaces canary-staged rollout with all-or-nothing ship language + Phase-7-deferred note pointing at \u00a74.3. README.md:57 drops [--canary-percent N] from the ship example. STABILITY DECLARED after R11. Three consecutive rounds (R7, R8, R11) with zero new Criticals. R11 explicit: 'convergence confirmed.' Finding-density trajectory across 11 rounds (new Criticals per round): R1: 3, R2: 1, R3: 2, R4: 3, R5: 3, R6: skipped, R7: 0, R8: 0, R9: 1* (regression-detect, not new), R10: 0, R11: 0 Total findings closed across all rounds: ~120. No further rounds scheduled. ARCHITECTURE.md header bumped v2.5 \u2192 v2.6. REVIEWS.md adds 'Rounds 7\u201311' section with per-round finding counts, notable findings, meta-observation on R9 (tooling/persistence issue Gemini caught that individual-file reviewers couldn't), and the convergence signal.
