# S103 (2026-07-06) — AI_INFRA 6-broadcast adap: crystallized-backfill + Harness-20 + memory-hygiene mapping

**Dev:** Claude Opus 4.8 (1M) Max (lead — S103 Fable-outage, H5-fallback revert-free) · em-main-led + 2 workflow (HMW-ON). **Scope:** governance/scripts-only, **0 prod-code** (Mig 61 · 89 bảng · 440 test · gotcha 79 · menu 54 GIỮ NGUYÊN).

## Directive (anh)
`/check-email AI_INFRA` + `/adap-apply`/`/adap-report`/`/adap-request` (evidence-gated) → `/fable-clone` invest→plan→**làm hết KHÔNG để docs** → `/ultra-on` fan-out Opus 4.8 Max → `/fable-clone` review → chốt report+request → `/session-end`.

## Adap (6 broadcast, hash MATCH cả 6 indep-recompute)
1. **Harness-20 fix-all-structure** (`bd714a33`) — engine **§L** codify (4-tầng NHÌN/NGUỒN/DẤU/DẪN-XUẤT + PERSONA · anti-asymmetric · 4-bước · 2-đầu). **Dogfood n=1:** model-note 4-tầng-sweep (`agents/README:3`-PERSONA + `session-start:37` + `session-end:113` Fable→Opus + engine `§G.5` 220K→380K neo-supersede; history-saga giữ). **2-đầu-catch:** review bắt 2 DẪN-XUẤT stale-trailer `rules:220`/`guides:428` (Opus 4.7→4.8) sweep-đầu-1 SÓT → fixed; ~14 `sessions/*.md:3` = SNAPSHOT giữ (phân-4-nhóm đúng). = convention, complements governance-detectors.
2. **harness-full-recheck F1-F4** (`94c78d1d`) — **F4 crystallized-backfill NEW** `scripts/crystallized-backfill.ps1` (measure-then-fill DRY NO-API; default target=0=OFF owner-authority READ-ONLY; calibrated-range [bytes/4..bytes/3.0]; precondition target>0∧headroom>0; value-gated source-order; **file-floor=UPPER-BOUND honest** — 6-file ~97K tok worst-case → 282K "headroom" NHƯNG peak~368K gần cap → real nhỏ hơn) + `budget.json:crystallized_backfill` + engine `§M.A`. **F1 already-met** (Lane-C sweep 0 hardcoded-violation, persona clean). **F3 already-met + live** (BƯỚC 0.6 bắt S103=Opus real-metadata). F2 = §L.
3. **session-cmd-budget-runloop** (`d47333e0`) — Up1 bảng-số-ngân-sách (live 0-hardcode) wire §2.1.6/§L.b(c) · **Up2 run-loop 2-tầng largely-ALREADY-MET** (§L.b(c) đã có H17-loop+%-print; formalize framing+number-block). engine `§M.B/§M.C`.
4. **H16 no-key Applied%** (`a1dc3a20`) — `scripts/applied-eval-nokey.ps1` cổng đối-kháng fail-closed (control-CAO→BLOCK/BỎ-QUÊN→BLOCK/thấp→PASS) + merge no-fabricate + selftest 3-ca (fault-inject FLIP bắt real-bug `$script:`-scope). **mechanism-built, numbers-DEFERRED**. 4 caveat. engine `§M.D`.
5. **memory-hygiene A/B/C** (`43c9e56f`) — A=archive-gate DRY-RUN (sidesteps grep-gate-trap) · B=governance-detectors 4-layer 1:1 · **C n/a-by-architecture** (JS-sandbox no-CLI-launcher) · wire already. **already-met via Harness-9/11**. engine `§M.F`.
6. **consolidation** (`5bba339b`) — REFERENCE-ACK: crystallization≠backfill absorbed · measurement-gap ack (calibrated-range tự-đo). engine `§M.G`.

## 2-workflow (Harness-9 mandate)
- **WF1 implement `wf_55ef6778-a0d`** — 3 lane schema-CLEAN (build 2 script selftest exit-0 + fault-inject teeth on scratchpad + Lane-C exhaustive verify). **3/3 return clean** (narrow-scoped).
- **WF2 review `wf_3c5c37cb-aa2`** (fable-clone ensemble H19, 3 reviewer-lane) — **Lane-C PASS returned** (hash + already-met file:line + no-overclaim + teeth + model-note + scope) + **Lane-B recover-from-memory PASS** (garbled return NHƯNG full review trong diary → recovered: §L/§M fidelity + 5 fault-inject + fix-all-structure verified). **0-BLOCKING, 2-CONCERN addressed** (STATUS/HANDOFF S103 blurb ✓ · tooling-auditor header-lag NIT). **1/3 return clean** (open reasoning-lane).

## Lessons / recurring-bug (value_protect)
- **#53 return-garble ×3 phiên này** (investigator recon + 2 review-lane) DESPITE schema+nudge → `feedback_agent_return_garble_recover` recover: **em-main solo redo** (investigator ground-truth) + **recover-from-diary** (Lane-B review file). Correlation evidenced: **build-workflow narrow-lane 3/3 clean vs review-workflow open-reasoning-lane 1/3** → garble ∝ open-ended reasoning task. → **adap-request** `2026-07-06-se-53-garble-reasoning-lanes-mitigation` (N-lane-redundancy + narrow-schema + em-main-recover mitigation).
- **AS-10 fired** (investigator garble-curated OWN memory: archive/2026-07.md new dù L1 KHÔNG over-cap 17337<25600) → **REVERTED** (git checkout + rm, git-diff commit-gate backstop, `feedback_monitor_residual_write_containment`). reviewer + tooling-auditor self-writes = LEGIT harvest (review-findings + monitor-diary), KEEP.
- **file-floor measure honest-nв̄c:** planner đo FILE-FLOOR subset → headroom = UPPER-BOUND; positive-floor-headroom vs "near-cap" narrative = HONEST iff partial-source caveat explicit (Lane-B lesson).
- **hash-verify-before-codify** (H18 discipline): 6 broadcast body-hash MATCH indep-recompute TRƯỚC khi codify (canonical split-`^---$` take-3rd + strip-1-newline + SHA256-UTF8).

## Deliverables (git)
2 script (crystallized-backfill.ps1 + applied-eval-nokey.ps1) · engine §L+§M · budget.json config · session-start §2.1.6 + session-end §L.b(c) wire · model-note 4-spot + 220K + 2-trailer · 6 adap-report + 1 adap-request · send-email `fc1e22ac` (selftest-MATCH) + STAGE-2 move 3-inbox + _index.

## Pending / NEXT
- **🔴 mark-proposal (report-before-stamp §L.b(h)):** Harness-20 + crystallized-backfill = governance-floor MỚI → propose Active-High, **CHỜ anh confirm** (P4/P8 KHÔNG auto-stamp).
- ⚠️ **restart CLI** (session-start/end + agents/README + 2 new command? no — chỉ doc/script). cicd verify Run (push có scripts/*.ps1 → CI CHẠY).
- **carry S97:** UAT incognito phiếu "8 MEP Sub solar" + số-phiếu/user "lỗi phân quyền".
