# Session 2026-06-15 S64 — Adopt Harness-7 (writing-quality floor) + check-email ai_infra

> Light governance session. Em main solo (0 sub spawn — bootstrap + check-email + governance authoring, đúng H6.1 trivial/governance-single-writer → solo). 1 commit `6afde19` (docs/gov-only) + closeout commit.

## Anh flow
`/session-start` → `/check-email ai_infra` (mailbox trống — guide cũ intact) → "trong thư mục all đấy" (chỉ em sang `outbox/all/`) → `/adap-apply` H7 + `/send-email ai_infra` → `/session-end`.

## Done
- **check-email ai_infra:** 0 email mới directed-to-se. UI/UX guide (`2026-06-11`) đã processed S58, whole-file hash MATCH (intact). Anh nhắc: broadcast cho-mọi-sister ở `outbox/all/` (kênh `/adap-apply`), KHÔNG phải `outbox/se/`.
- **Delta `outbox/all` vs adap-reports:** 13 broadcast vs 12 applied → **1 mới = Harness-7** (`2026-06-15-Governance-harness-7-writing-quality`, từ frontend-designer-floor → harness-6 đều đã áp).
- **Adopt Harness-7** (`6afde19`, 6 file +106/−1): rule canonical `rules.md §1.1` (O1 outward full-grammar VN · O2 asymmetric nội-bộ-giữ-nén §6.4/§6.5 · O3 reviewer-gate + self-check) + `reviewer.md Category 6` (conditional outward) + `README Upgrade S64` + adap-report + email se→ai_infra + `_index.md` OUTBOUND.
- **Email sent:** `broadcasts/outbox/ai_infra/2026-06-15-se-to-ai_infra-harness-7-adopt-report.md` (body-hash `7e4f91f1` self-verified MATCH; file LF-pinned qua `.gitattributes broadcasts/** eol=lf`).

## Key facts / lessons
- **Body-hash verify story (gotcha #61 family):** broadcast `content_sha256 a4580ea9` — lần verify đầu báo "mismatch" nhưng = LỖI CỦA EM: PS5.1 `Get-Content -Raw` đọc UTF-8-no-BOM bằng Windows-1252 → giải mã sai tiếng Việt → hash tính trên chuỗi đã hỏng. Đọc lại `[IO.File]::ReadAllText($f,[Text.Encoding]::UTF8)` → MATCH tuyệt đối. → **KHÔNG mis-stamp / KHÔNG tamper** (khác adap-request S63 `eol=lf` vốn là class lỗi cross-checkout có thật). **Lesson:** verify body-hash trên Windows PHẢI đọc UTF-8 tường minh; đừng cry "mis-stamp" trước khi loại trừ decode-bug của chính mình.
- **Dogfood H7:** từ giữa session em sửa lối viết — 2 báo cáo đầu (bootstrap + check-email) đã rò lối nén nội bộ ra ngoài (cụm cụt ngủn, dày ký hiệu).

## Nấc adoption (G-011)
- rule + reviewer wiring = **executed-file**.
- lead self-check = **verified-live** (responses + adap-report + email viết theo H7 ngay session này).
- reviewer Category 6 thực thi = **verified-pending-restart** (agent `.md` no hot-reload).

## State (unchanged — docs/gov-only)
Mig 50 · 88 bảng · 263 test (N/A re-run — 0 code change) · 64 gotcha · menu 53 · RAG 2423 · bundle admin `0xKYGhhf`/user `C81ZdG9G` Run #286. Lead = Opus 4.8 (1M) (H5 fallback, Fable down 06-12).

## §L closeout
- **§L.a:** 0 shipped error. UTF-8 false-mismatch self-corrected pre-send = near-miss → reinforce gotcha #61 (no new RCA-class — caught + corrected, 0 outward impact).
- **§L.b:** (a) STATUS Recently Done +1 ✓ · (b) guard E-005 git-add-specific-files held (staged 6 file cụ thể) ✓ · (c) cicd-monitor L1 62KB bloat + inv-codebase 31.9KB + reviewer 31.2KB >soft-cap → **monthly 2026-07-01** · (d) flush n-a (0 sub) · (e) anh ops-items logged SPECIFICS ✓ · (f) harvest GATE n-a (0 sub / 0 wave) · (g) tooling: reviewer +Category 6 (đã document README), 0 new skill/plugin alloc, backlog deferred → inline chốt (em main), KHÔNG spawn monitor (proportionate cho light session).

## NEXT
- **⚠️ RESTART CLI** activate reviewer Category 6 (verified-pending-restart).
- **H5.6 restore** khi Fable 5 về (no-ETA): đổi lead lại + spawn-test + gỡ caveat.
- **Anh ops (giữ S58/S59):** tzutil VPS · anh Chương email → dọn typo · báo 5 real staff password `User@1234567` · gán CNTT → lock nv.cao/nv.truong.
- **Monthly audit 2026-07-01:** STATUS/HANDOFF re-tier (defer ×4) · cicd-monitor L1 62KB curate · schema-diagram §16+ Mig 32-50 ERD.
