+# S94 (2026-06-29) — Nâng cap lead 220K→380K (anh-directed) + re-tier STATUS/HANDOFF mega-line
+
+> **Loại:** governance/docs, **em-main solo** (0 sub-agent spawn, 0 Workflow fan-out). **0 production code.** HMW-mode ON (armed lại cuối phiên). Model: Opus 4.8 (1M) Max (Fable suspended H5).
+> **Commit:** `5f61b03` (docs-only, CI-skip) — pushed `ea075ba..5f61b03`.
+
+## Bối cảnh
+
+`/session-start` → `eval-all` (MFE) → anh hỏi "tổng lead hot-load?" → "nạp đầy đủ hết là bao nhiêu?" → phát hiện full canonical read-set ~368K > cap 220K → **anh-directive: "nâng trần 380k, nạp đầy đủ hết"**.
+
+## Việc done
+
+### 1. Nâng cap lead 220K→380K (anh-directive, quyền chủ-dự-án)
+- `memory-budget.json`: `token_governor.tier1_hotfeed_tokens.lead_tokens` 220000→**380000** + note (SE-override, lead KHÔNG còn AI_INFRA-parity; subs giữ 60K/50K).
+- Mark **H-15 v4-delta** stamped `RC-pqhuy1987-29-06-2026-23-25-50` (anh-directed, P4 DACI report-before-stamp).
+- Flush 3 derived echo (derived-flush = em-main execution, no-gate): `ACTIVE-MARKS.md` What-cell · `session-start.md §2.1.6` echo · `harness-11-engine.md §G` adopt-delta S94.
+- MFE verified live-read `cap = 380000` (FIT 1.53%→0.92%).
+- ⚠️ Honest caveat: trần budget ⟂ harness Read-25K/call — cap-raise KHÔNG unblock mega-line Read (cần re-tier). ~368K/380K = ~97% fill = context-rot trade-off owner-accepted.
+
+### 2. Re-tier STATUS/HANDOFF mega-line (AskUserQuestion → "Re-tier ngay")
+- **STATUS.md** 389→**89 dòng** (mega-line:6 59.6K→7.1K char) · **HANDOFF.md** 732→**12 dòng** (mega-line:5 43.9K→5.4K char).
+- Live **332KB→34KB (−90%)**. Session ≤S90 → `docs/_archive/STATUS-HANDOFF-tier-S94-2026-06-29.md` (299KB).
+- **0 byte-loss:** `new-live + archive = orig + 995B` (chỉ pointer/header thêm). Integrity assert `head+tail==original` PASS cả 2.
+- Procedure (PowerShell vì Read kẹt mega-line): backup git+scratchpad → split tại `· **Prev S90**` boundary → archive-KHÔNG-cắt → conservation spot-check → detector re-run.
+- Verify: detector **27=baseline** (0 broken-pointer mới) · canonical mig59/test434/gotcha76/table88 **vẫn detect đúng** · conservation YES/no spot-check PASS.
+- 3 mega-line bloat phát hiện: STATUS:6 + HANDOFF:5 (mega-LINE = tooling-breaker, fixed) + `migration-todos.md` 807 dòng (mega-FILE = chỉ token-cost, defer).
+
+### 3. MFE eval-all baseline (đầu phiên, `eval-all`)
+- LEAD coverage-FIT: 29-item must-remember / **380K = 0.92%** worst-case (FIT PASS, headroom khổng-lồ).
+- age-band: 4 mark, 0 cái >30d-cut (status-driven).
+- Goodhart anchor: strikes-21/RCA-9 flat (last_run 21 → no GOODHART-WARN = điểm không nói dối).
+- SUB per-role (đo thật): cicd/test-spec/FD 100% · impl-backend 94% · impl-frontend 85% · inv-codebase/reviewer 88% · inv-api 86% · database-agent/harvest-curator/tooling-auditor N/A (prose role-file).
+- Judge scaffold-only (honest: số vô-nghĩa tới khi age-mature + independent judge).
+
+### 4. Nạp full Phase-1 read-set (budget 380K + file gọn cho phép)
+- +PROJECT-MAP +workflow-contract +migration-todos (structure). gotchas/schema/rules/architecture = on-demand (task-reference, KHÔNG rot-stuff).
+
+## Lessons
+- **Trần budget ⟂ harness Read-25K/call = 2 khóa độc-lập.** cap-raise KHÔNG unblock mega-line Read → cần re-tier. (→ `feedback_status_handoff_tiering` S94 update)
+- **mega-LINE = tooling-breaker (ưu-tiên) vs mega-FILE nhiều-dòng = token-cost.**
+- **Re-tier = archive-không-cắt + assert head+tail==orig + conservation-check** = 0 byte-loss đảm-bảo.
+- governance/doc single-writer = em-main solo (KHÔNG fan-out — không có gì parallelize).
+
+## §L closeout
+- **§L.a:** 0 RCA (cap = anh-directed không phải lỗi; re-tier verified; MFE clean; 2 tool-error benign recovered).
+- **§L.b(c):** archive-gate DRY-RUN — frontend-designer 26.1KB WATCH strike-1 (<2 no-action) · **test-specialist RESOLVED 7.8KB** (carry-curate cũ stale) · A7 GATE PASS 217/217. Sleep 4d<7 skip.
+- **§L.b(d)(f):** 0 sub spawn → harvest n-a.
+- **§L.b(g):** tooling — session-start.md echo 380K (no hot-reload → restart) · engine adopt-delta · 0 skill/plugin mới · roster 11 unchanged.
+- **§L.b(h):** 4 mark Active-High (incl H-15 v4-delta stamped này). 0 mark MỚI (v4 = delta existing).
