+- **S82 (2026-06-21) Harness-15-v2 adopt review (governance delta, 0 code) — 3/3 lane PASS:** floor-completeness + faithfulness + honesty-regression, all clean ("genuine PASS not courtesy"). Caught 3 MINOR (đã fix): volume "~42K" stale trong mark · mark What-cell mang nội-dung S82 mà status ghi "anh-confirm S81" → flag pending-confirm · `_index` pending. **Memory-note (chống false-alarm):** `broadcasts/_index.md` sha = notify's **self-declared `content_sha256`** (frontmatter), KHÔNG recompute full-file/body → đừng flag index-vs-file "mismatch" trước khi đọc frontmatter field. **Stamped-mark mid-session edit OK** khi chỉ refresh What-cell content của decision đã-confirm + status flag pending (KHÔNG mint RC-sig mới, KHÔNG đổi tier) = accuracy-keeping, không phải frozen-record breach.
 - **S76 (2026-06-19) PE budget ma-trận 3 cột Mig 56 + badge display-only — PASS:** MAJOR race = 2 PRO cell cùng-cột share mutation + echo sibling từ `bs` + fire-and-forget `invalidate()` → data-loss window (fixed **gotcha #70** useIsFetching gate). Badge role-set MUST mirror gate bit-for-bit (đảo-chiều set-lookup = forward Roles.Contains). **SURPRISE:** spec "KHÔNG migration" FALSE (diff bundle Part1+2+3) — đừng tin scope-framing em-main, đọc changed-set thật. → _INDEX S76 Part1/Part2+3.
 - **S72/S72bis/S72ter/Q2 (2026-06-18) Mig 54 PE giá-đề-xuất + CCM-finalize OPT-IN — financial go-live PASS:** fail-closed guard ORDER = throw TRƯỚC mọi set `Phase=DaDuyet`; no-deadlock proof = submit-guard invariant (`winnerQuoteTotal>0`) forward-trace tới finalize candidate-set (FE `length===0` branch unreachable); finalize-bypass = 3 gate trực-giao (approver-match ∩ role=CostControl ∩ amount<threshold) + server-recompute amount KHÔNG trust-client; isSystem-exempt = dead-branch single-caller-proof. → _INDEX S72*.
 - **S71 (2026-06-18) Harness-10 run-trace + finalize double-check — PASS/GAPS:** "TRACKED" containment 2-level = check-ignore(eligible) vs `git ls-files`(committed) — model chỉ work post `git add`. "Hoàn chỉnh toàn bộ" audit phải check `budget.json` measured-bytes vs DISK (over-cap re-accumulate mỗi session). → _INDEX S71*.
