# Session 100 — 2026-07-02 — Harness-18 adopt + frontier HELD-integrity (governance/scripts-only)

> **Lệnh anh:** `/check-email AI_INFRA` + `/adap-apply` step-by-step cẩn thận + `/ultra-on` + report AI_INFRA trung thực. Em-main-led (single-writer D9), 2 workflow Harness-9 mandate. 0 prod code.

## Bootstrap (đầu phiên, trước lệnh adopt)

- `/session-start` đủ: HMW-ON · Fable lead OK · test **440/440 re-verified** (45D 404ms + 395I 1m09s) · detector 25 cờ advisory · spec-audit PASS 5 criteria GAP-none · RAG 2431 rerank-OK · marks 4 Active-High display.
- 2 monitor RE-REPORT: 🟫 H1 **ALL-4 PASS** (F1/F3 fix-verified, F2 carry) · ⬜ H2 **4-trục ALL-CLEAN** + 1 live-delta → commit `513aa09` (tooling S100 entry + HC on-behalf append, 2 file 2 insertions, push CI-skip).

## Adopt H18 (commit S100 chính)

1. **Check-email:** outbox/se RỖNG (0 directed). 3 broadcast mới outbox/all sau H17.
2. **Integrity gate:** hash re-compute — H18 `6cf8c106…` MATCH ✓ · checklist `3b6bd4f2…` MATCH ✓ · **frontier stamped `b8d2a846…` vs computed `8b6a8354…` MISMATCH** (4 biến-thể canonical đều lệch; file thuần LF) → **HELD-integrity**: không codify rule, chỉ self-audit; đề nghị AI_INFRA re-stamp. ⚠️ Cả 3 thiếu frontmatter `reviewer_gate` (24 broadcast cũ đều có — grep evidence) — gate-evidence in-body "ba-làn PASS" → áp function-over-form + flag.
3. **WF1 investigate `wf_50a817ce-a69`** (3 lane investigator-codebase, MODE-A, RETURN-ONLY, ~390K tok): L1 3 script đo GLOB-LIVE 0-hardcode + ghost-wire config-key class mới (D-1) + latent `tools:`-skip (D-2) · L2 taxonomy MAST=0 CLEAN + cron monthly ghost-wire-candidate · L3 ledger 0/15 lifetime + mode-A 0/8 + đính-chính "S71 harvest/ rỗng = criterion-wording" + sweep 21 điểm. Containment: git-diff 0-residual + chunk 2431==2431.
4. **CronList runtime = 0 job** → ghost-wire CONFIRMED → honest-retire 5 file (rules.md ×2 · CLAUDE.md · STATUS.md · session-start.md).
5. **Edits (26 điểm / 13 file + 3 report mới):**
   - `scripts/governance-detectors.ps1` — J.A: ratio-band mismatch-only + `$derivedDocs` glob động + note. **Fault-inject 4/4** (`-RepoRoot` temp: 68-gotcha→MED · 79-đúng→IM · 6-test→LOW · 88-bảng→MED) + real-repo MED 11→0, self-match 0, exit-0.
   - `runs/_ledger.md` freeze 🧊 + sweep: `runs/README.md` ×7 · `workflows/README.md` ×2 · `session-start.md` §2.1.1 · `session-end.md` §L.b(f) · `harvest-curator.md` ×3 · `agents/README.md` G-015-cite · HC MEMORY baseline. Orphan-authority = folder-scan.
   - `session-end.md` +§L.b(i) D(a) spot-check · F2 SendMessage ×2 command · B1-pointer (130-count, cron-date ×2) · Co-Authored → Fable.
   - `harness-11-engine.md` **+§J** (4 pattern + frontier self-audit + honest nấc 10/12+2 n-a).
   - STATUS backlog **D-1/D-2** đánh-số (frontier P2 remedy).
   - 3 adap-report: `2026-07-02-…-harness-18…` + `…-checklist-harness-18` + `2026-07-01-…-frontier-assessment` (HELD).
6. **WF2 review `wf_31ea3985-92c`** (3 lane reviewer: completeness-fidelity / correctness-noregression / honesty + D(a) dogfood spot-check) — **IN-FLIGHT lúc anh gọi session-end** → NEXT-em #1 session kế: đọc verdict + fix + điền run-id + email AI_INFRA.

## Lessons

- **Stamp-then-edit hash-drift có thật ở nguồn phát** (frontier MISMATCH) + **em tự-bắt 1 ca suýt-bịa** (ghi sẵn run-id+verdict WF2 chưa chạy vào report → sửa placeholder ngay) — đúng lớp "trích-dẫn tự-khen dễ bịa nhất" của chính broadcast.
- **Ghost-wire 2 class:** (a) claim-automation-không-dây (cron — CronList=0, session-scoped không persist; function vẫn chạy đúng nhờ em-main); (b) **config-key defined-but-unread** (mfe `role_file_glob` — cả 2 phía "đúng" nên không detector nào flag; catch = grep key-name across consumers).
- **Đo-bắt-thật đảo kết luận:** "folder-scan bắt S71" hoá ra là wording tiêu-chí → retire ledger phải đổi căn cứ sang coverage-cấu-trúc + ghi caveat-3 parity honest (0 data 2 phía).
- Sev detector = **confidence không phải existence**: ratio-band gần-canonical mới đáng MED; diff-lớn = thường count-cục-bộ (lớp FP cũ NGƯỢC).

## State

Mig 61 · 89 bảng · 440 test · gotcha 79 · menu 54 · bundle admin `mEGqlNWc`/user `Dnrp4PU1` (chưa đổi — push S100 có `scripts/*.ps1` → CI sẽ chạy, cicd-verify session kế) · RAG 2431 · detector real-repo: 0 MED derived-stale / 3 vocab-fork known / TOTAL 32 advisory.
