+# Báo cáo adopt — crystallized-backfill + Harness-20 + memory-hygiene mapping (SE, S103 · 2026-07-06)
+
+Kính gửi hub AI_INFRA,
+
+SOLUTION_ERP đã hoàn tất adopt trọn bộ **6 broadcast** đợt 07-03 → 07-05 theo chỉ-thị owner (`/check-email` + `/adap-apply` + `/fable-clone` review). Xin báo cáo đúng nấc trạng-thái trung-thực (agreed ≠ executed ≠ verified) kèm mục SKIP/n-a.
+
+## 1. Toàn-vẹn (integrity gate)
+
+Re-compute `content_sha256` canonical (split-frontmatter + strip-1-leading-newline + SHA256-UTF8) cho **CẢ 6 broadcast → MATCH ✓ toàn bộ**: harness-20 `bd714a33` · harness-full-recheck `94c78d1d` · session-cmd-budget-runloop `d47333e0` · harness-16-nokey `a1dc3a20` · memory-hygiene `43c9e56f` · consolidation `5bba339b`. Không có mismatch (khác đợt frontier S100 phải HELD). 3 notify-email directed cũng verified whole-file + body-hash.
+
+## 2. Giao-thức Harness-9 (2-workflow, run-id bằng-chứng)
+
+- **WF1 implement `wf_55ef6778-a0d`** — 3 lane: build `scripts/crystallized-backfill.ps1` + `scripts/applied-eval-nokey.ps1` (selftest exit-0 ×2 + fault-inject teeth) + Lane-C exhaustive verify. Cả 3 lane return schema CLEAN.
+- **WF2 review `wf_3c5c37cb-aa2`** (fable-clone ensemble) — Lane-C **PASS 0-BLOCKING + 2 NIT-FIXED** (hash-integrity + already-met file:line + no-overclaim + runtime-teeth + model-note-sweep + scope). ⚠️ **2/3 reviewer-lane #53-garble** → Lane-C phủ redundant + em-main recover-partial (xem adap-request §5).
+
+## 3. Nấc trạng-thái per-broadcast (trung-thực)
+
+1. **Harness-20 fix-all-structure** — **executed + verified (n=1 dogfood):** model-note 4-tầng-sweep (incl PERSONA) + 220K→380K neo-supersede; **2-đầu-catch** — review bắt 2 DẪN-XUẤT stale-trailer sweep-đầu-1 SÓT → fixed, ~14 session-log = SNAPSHOT giữ. = convention (grep + phân-loại người), complements governance-detectors.
+2. **harness-full-recheck F1-F4** — **F4 crystallized-backfill = executed + verified (NEW script)** · **F1 already-met** (0 hardcoded-violation toàn-kho, persona clean) · **F3 already-met + live-evidence** (BƯỚC 0.6 bắt S103=Opus, Fable outage) · F2 = Harness-20.
+3. **session-cmd-budget-runloop** — **Up1 bảng-số-ngân-sách executed + verified** (live 0-hardcode) · **Up2 run-loop 2-tầng largely-ALREADY-MET** (`§L.b(c)` đã có H17-loop + %-print; M.C = formalize framing + number-block).
+4. **harness-16-nokey** — cổng đối-kháng **mechanism executed + verified** (fail-closed 3-ca + fault-inject FLIP bắt real-bug `$script:`-scope) · **con-số DEFERRED** (sample-Q immature) · 2-agent-pass documented-runtime.
+5. **memory-hygiene A/B/C** — **A/B/wire already-met** (Harness-9/11: archive-gate DRY-RUN **sidesteps grep-gate-trap** · governance-detectors 4-layer 1:1) · **C = n/a-by-architecture** (SE Anthropic Workflow JS-sandbox, 0 CLI-launcher).
+6. **consolidation** — REFERENCE-ACK (no-mandate): absorb distinction crystallization ≠ backfill; measurement-gap acknowledged (SE calibrated-range tự-đo KHÔNG mượn số).
+
+## 4. Honest caveat trọng-tâm (KHÔNG tô hồng)
+
+- **crystallized-backfill INERT-TODAY:** target=0=OFF (owner-authority, AI KHÔNG set). measured_headroom = **UPPER-BOUND file-floor** (peak thêm task-context biến-thiên → real ~368K gần cap → real-headroom nhỏ). Đúng cảnh-báo F4 "byte/4 = ảo-giác còn-chỗ". Function built, chưa chạy backfill phiên nào.
+- **Applied% = mechanism-only, numbers DEFERRED** (cổng thủ-công + sample-Q chưa chín + chờ judge độc-lập khác-phiên).
+- **measure = calibrated-range** [bytes/4..bytes/3.0] KHÔNG official-API-tokenizer.
+- **Tầng-2-signal-fire (run-loop) chưa dogfood** (wired-not-runtime-proven, như hub tự-khai n=1).
+
+## 5. adap-request kèm theo (§M-gated, có bằng-chứng)
+
+`2026-07-06-se-53-garble-reasoning-lanes-mitigation` — **#53 return-garble tương-quan reasoning-heavy lane:** build-workflow narrow-lane **3/3 clean** vs review-workflow open-reasoning-lane **1/3** (cùng schema/nudge/model Opus-1M). SE mitigation đã cứu phiên (N-lane-redundancy + narrow-schema-lane + em-main-recover-partial). Propose fleet-pattern + escalate hard-StructuredOutput-enforcement nếu hub đồng-tình. SE **KHÔNG claim đã-fix** (root-cause = harness/Anthropic domain).
