+Em main đọc `.claude/fable-real-mode.on` → **BÁO ngay** (mode phán-quyết 2 vị-trí `reviewer` + `investigator-codebase`):
+- **Marker TỒN TẠI** → **🔴 Fable-real mode = ON** — 2 vị-trí phán-quyết chạy SINGLE top-model THẬT (deep pass). `/fable-clone` về ảo-ensemble.
+- **Marker KHÔNG có** → **🟢 Fable-clone mode (MẶC-ĐỊNH, ảo)** — 2 vị-trí chạy ensemble tier-2 (N lane CÙNG vai + em-main synthesize) khi heavy-judgment. `/fable-real` bật thật.

Đổi mode = quyền anh gõ lệnh (KHÔNG auto/số-dư). ⚠️ **Vacuously-inert dưới all-inherit + Fable-outage** (2 vị-trí đã top-model) → báo-mode để future-proof + nhắc anh khi Fable về + phân-tầng. (Reader này đóng gap WF2-Lane-A "marker write-only": marker giờ có consumer.)

 ## 📋 BƯỚC 0.6 — Model-availability check (H5 — adopt S63)
 
 Em main xác nhận **lead model resolve được** đầu session. Lead SE = **Fable 5 (1M) Max** (per H4). **DOWN** = lỗi `"Model isn't available — claude-fable-5[1m]"` → fallback **`/model claude-opus-4-8[1m]`** (Opus 4.8 · 1M · Max — top-tier, KHÔNG hạ §A1; **KHÔNG sửa frontmatter agent** — promote `inherit` tự theo lead → two-tier tạm collapse single-tier Opus, **revert-FREE** khi Fable về). Phản xạ THỦ-CÔNG (không hook tự-switch). ✅ **Fable RESTORED 2026-07-02 (S98)** — lead chạy `claude-fable-5[1m]` (settings.json:11) + spawn-test inherit ×2 monitor self-report `claude-fable-5` → H5.6 hoàn tất, caveat suspended-2026-06-12 (fallback Opus S62→S97) đã gỡ. Nếu DOWN lại → fallback theo quy trình trên.
