## Nấc per-lesson (F1-F4 · G-011)

| Lesson | Nấc | Evidence |
|---|---|---|
| **F1 — số cấu-hình = trỏ-tham-chiếu KHÔNG sao-chép** | **already-met (verified)** | Lane-C exhaustive sweep = **0 hardcoded-violation** toàn-kho; persona `.claude/agents/*.md` CLEAN (0 bare-cap); mọi cap-số kèm pointer (budget.json / "đọc số sống" / lịch-sử-mark). M.B budget-table live-read retire echo `session-start:122`. |
| **F2 — sweep đủ-tầng INCL persona** | **executed (= §L Harness-20)** | model-note 4-spot sweep + persona-tier `README:3` (reload-mỗi-spawn). Chi-tiết → adap-report §L. |
| **F3 — model-routing bằng REAL-metadata** | **already-met (live-evidence S103)** | BƯỚC 0.6 đọc env-runtime-thật → **S103 bắt runtime=Opus** (Fable outage) KHÔNG tin comment "S102-Fable". Đúng bài F3 "ghim thắng inherit khi model blank → đứt âm-thầm"; SE all-inherit + probe-metadata mỗi phiên. |
| **F4 — crystallized-backfill (measure-then-fill) NEW** | **executed-file + verified** | `scripts/crystallized-backfill.ps1` (NO-API DRY planner; selftest exit-0; fault-inject 3-branch teeth trên scratchpad-fakeroot: default→0 / target+headroom→min-binds / headroom≤0→0; owner-read-only grep-0-write budget.json). config `budget.json:crystallized_backfill` (target=0). engine `§M.A`. |

## Tailored / Skip / Phản-biện

- **F4 5-sàn honored:** default-0=OFF (owner-authority) · NOT-for-sub · calibrated-RANGE [bytes/4..bytes/3.0] worst-case · PRECONDITION target>0 AND headroom>0 · value-gated source-order (gist→value-marked-archive→curated-RAG) DRY-no-pour. 🔴 **DISTINCT crystallization** (§I distill = nén-về-nguồn giữ time-invariant) vs backfill (ĐỔ-vào-trống) — 2 hướng ngược (consolidation Mục 1).
- **🔴 Honest caveat trọng-tâm — INERT-TODAY:** target=0 (AI KHÔNG set — owner quyền). measured_headroom = **UPPER-BOUND file-floor** (6-file ~97K tok worst-case → 282K "headroom"; NHƯNG peak thêm task-context biến-thiên KHÔNG trong list → real peak ~368K gần cap → real-headroom NHỎ HƠN nhiều). = đúng cảnh-báo F4 "byte/4 undercount + partial-list = ảo-giác còn-chỗ". backfill KHÔNG chạy phiên nào (mechanism built, inert-until-owner).
- **Skip:** KHÔNG set target>0 (owner-authority). measure = calibrated-range KHÔNG official-tokenizer (measurement-gap fleet-wide).

## Codify + hậu-kiểm

- Engine `§M.A` (F4) + `§M.E` (F1/F2/F3 mapping). script + config + budget-table wire.
- Nấc tổng: **F4 executed+verified · F1/F3 already-met (verified) · F2 = §L**. reviewer_gate PASS. Run-id WF1/WF2 như trên.
