# Session S70 (2026-06-17→18) — Harness-9 adopt: L2 archive dark-matter recovery + adap 2-workflow mandate

> em main + 3 Workflow (12 agent) + 2 monitor bootstrap. **0 production code** (governance/memory only). Commit `f36aab8` pushed.

## Trigger
Anh: `/session-start` → `/check-email AI_INFRA và /adap-apply Harness-9` → chốt scope **"đầy-đủ-nhất, làm cẩn thận từng stage — investigate → implement → audit"** → `/session-end`.

## Bootstrap (/session-start S70)
- **2 monitor RE-REPORT:** 🟫 H1 — 3 skill cite stale (`dependency-audit-erp/SKILL.md:153`, `skills/README.md:20`+`:90`) + curate-debt 4 agent over-cap (cicd 63.6KB worst · inv-codebase 45.9 · reviewer 42.5 · impl-backend 32.4). ⬜ H2 — CLEAN, 0-orphan, 5-trục PASS (S69 fully harvested).
- RAG `proj_solution_erp` alive **2426 chunks** (stale-index 05-29). test **306 baseline verified** (45D+261I). HMW-mode ON. Lead Opus 4.8 (Fable suspended H5 fallback).
- `/check-email AI_INFRA`: `outbox/se` chỉ UI/UX guide (processed S58) → **0 thư mới directed**. Harness-9 ở `outbox/all` (kênh `/adap-apply`, S64 lesson).

## Harness-9 = 2 phần
- **PART 2/3 (🔴 function-floor):** mỗi adap = 2 workflow tách biệt (IMPLEMENT + REVIEW double-check) + REPORT-kèm-run-id; task ngắn-nhưng-cần-confirm VẪN cần review-workflow.
- **PART 1 (proposal, tailor tự do):** cứu L2 archive dark-matter — gist-additive + `_INDEX.md` TOC + budget seed-by-measure + budget-audit @session-start + command nén-gist tách build-index.
- PROJECT-FIT cao: SE có ~240KB archive dark-matter thật (4 over-cap sub), trùng đúng P1 curate-debt.

## Stage A — INVESTIGATE (`wf_be952f3c-97f`, 4× investigator-codebase)
Recon 4 archive → build-plan. **Quyết định pointer = substring sha-keyed** (4 agent đồng thuận độc-lập): anchor-slug 404 dễ (slug-collision same-date; reviewer q3 hai `## 2026-05-22` identical; cicd `2026-06.md` ZERO heading = bullet; Vietnamese-diacritic/em-dash slug-fragile). git-sha 7-char = immutable + grep-unique. KHÔNG line-hint (additive append shift dòng). + per-agent moveToArchive list + importantMarkers checklist (83 total, làm gate Stage C) + risks.

## Stage B — IMPLEMENT (`wf_a58e0d15-beb`, 4× general-purpose, file-disjoint)
Mỗi sub: curate L1→L2 byte-exact → `_INDEX.md` → `.gist.md` (theo thứ tự, để index/gist phủ trạng-thái cuối).

| sub | L1 trước→sau | moved | markers | `_INDEX` ptr |
|---|---|---|---|---|
| cicd-monitor | 65→**23.2KB** | 10 | 22/22 | 76/76 |
| investigator-codebase | 47→**24.1KB** | 15 (tạo `2026-05-q4.md` fresh — was git-only d2f52ba) | 22/22 | 37/37 |
| reviewer | 43.5→**24.8KB** | 9 | 19/19 | 19/19 |
| implementer-backend | 33→**17.4KB** | 14 | 20/20 | 41/41 |

Cả 4 <25KB auto-inject cap → **P1 curate-debt CLOSED**, ~240KB archive hết RAG-dark.
**Em-main shared (single-writer, ngoài workflow):** `memory-budget.json` (seed-by-measure — cicd `_INDEX` 16.8KB largest = **82% of 20KB cap, WATCH-agent**) + `scripts/measure-agent-memory.ps1` + `.ragignore` + codify PART 2/3 (`adap-apply.md` mandate + `agents/README` Upgrade S70 + `session-start §2.1.2` budget-audit).

## Stage C — AUDIT (`wf_9520d8cd-4fe`, 4× reviewer, independent)
- reviewer **PASS** (50/50 markers, 19/19 ptr, 0-byte airtight) · implementer-backend **CONCERN** (read-side gap `memoryPointsToIndex:false` + stale curate-log).
- **2 (cicd + inv-codebase) no-StructuredOutput** (after 2 nudges) → em-main **self-gate** via git/sha/grep (recovery-path `feedback_agent_kill_recovery`).
- **4/4 0-byte-loss PASS:** git numstat `+N -0` (additive, 0 deletion trên verbatim modified) + frozen `2026-05-*` sha256 IDENTICAL + content-identity (inv-codebase `2026-06.md` rebuilt → CR-normalize prefix byte-exact; git autocrlf normalizes on commit).

## Findings fixed before commit
- **Read-side gap (3/4):** cicd/inv-codebase/impl-backend `MEMORY.md` không trỏ `_INDEX.md` → agent spawn không biết đường tra map (read-side mechanism inert). Fixed L5 header → `_INDEX.md` + `2026-06.md` + gist. (reviewer đã sẵn.) **Stage-C độc-lập bắt = giá trị review-workflow riêng** (implement tự-chấm bỏ sót) — đúng lý-do PART 2 tách 2 workflow.

## §L closeout
- **doc-drift 4 flush (H1):** `dep-audit:153` 65→68 · `skills/README:20` 52→53 (+Mig 52→53 + label S65→S69) · `:90` 65→68 · `session-start:44` (58)→(68).
- **4 curate-log refresh S70** (was stale S40/S66/S69).
- **H2 GATE CONDITIONAL PASS:** Corruption/Placement/Fidelity 🟢 (md5-proven 0-loss, 0 stray cwd, no-fabrication); Coverage/Completeness 🟡 (spawn-record fill via curate-log + 3 `S?`-label cosmetic worker-artifact trong impl-backend `2026-06.md:1`/`_INDEX:51`/`MEMORY:77` — content intact, label-only).
- **Wave-folder:** n/a (Workflow tool direct, không wave-mode → 0 `.claude/workflows/wave-*/`).

## Phase 6 EVAL — infra-adoption (§6.3)
Harness-9 = infra/governance adoption. **adap-report** `docs/governance/adap-reports/2026-06-17-Governance-harness-9-l2-recovery-and-adap-workflow.md` (G-011 = executed-file + VERIFIED). **email-back** `broadcasts/outbox/ai_infra/2026-06-17-se-to-ai_infra-harness-9-adopt-report.md` (body-hash `7c07b716e775`) — 3 đề-xuất ngược: (1) substring-pointer-keyed-on-sha cho archive đời-thực · (2) measure-then-seed reference impl · (3) self-gate-fallback hợp-lệ cho review-workflow khi auditor không return. SERVER-VERIFIABLE: commit `f36aab8` + closeout commit origin synced.

## State (UNCHANGED — 0 production code)
**Mig 53 · 88 bảng · 306 test · 68 gotcha · menu 54 · bundle admin `BgNCjwsG`/user `CBvh0vtf`.**

## Lessons
- **substring-pointer > anchor-slug** cho archive trộn heading-level + same-date + diacritic — git-sha là khoá ổn-định nhất.
- **REVIEW-workflow riêng có giá-trị thật** (bắt read-side gap implement bỏ sót) — PART 2 dogfood đúng trên chính nó.
- **self-gate-fallback** khi reviewer no-StructuredOutput (#53 family) = nhánh hợp-lệ, KHÔNG FAIL adopt. → memory `feedback_harness9_l2_recovery_2workflow_adap`.

## NEXT
- ⚠️ **Restart CLI** (đầu việc): session-start §2.1.2 budget-audit + (tồn) H8 all-inherit runtime + reviewer Category 6.
- **Budget-audit @session-start (mới):** cicd `_INDEX` 16.8KB/20KB cap (82% — gist-of-index/split khi vượt, đừng drop marker).
- **Pending product carry S69:** CEO-threshold Designer + cờ gấp PE test; "C" chờ spec. Ops S58/S59 (tzutil · anh Chương email · 5 real-staff pw · gán CNTT lock).
- **Monthly audit 2026-07-01:** STATUS/HANDOFF re-tier (trim S67↓→logs, defer ×9) · docs/CLAUDE deep-doc count-flush (gotcha 58→68 · 93→88 bảng · Budget-removed) + schema-diagram §16+ Mig 32-53 ERD · rollout Harness-9 `_INDEX`/gist cho sub khác KHI archive lớn lên.
- **Cert** `api.solutions.com.vn` ~2026-07-23 (auto-renew ~06-23).
