B1 playbook_service.py: evolver setattr傳str而非PlaybookStatus enum
→ _pg_upsert playbook.status.value炸（163次/48h），修：update_with_validation強制enum轉型
B2 approval_db.py + webhooks.py: find_by_fingerprint PENDING誤收斂
→ PENDING≠Telegram已發；修：成功push後mark tg_sent:{fingerprint} Redis(24h TTL)
→ find_by_fingerprint debounce窗外PENDING必須Redis確認才收斂
drift_adopt_service.py: telegram_gateway呼叫adopt_drift(report_id)但方法不存在
→ 新增adopt_drift()包裝：從DB載入DriftReport後委派adopt()，修復採納失敗
B3 ai_slo_watchdog_job.py + main.py: AI無法感知自身故障（MASTER §1.1盲區）
→ 新增每15分鐘自健診：W-1 SLO違反 W-2 TG靜默偵測 W-3 飛輪成功率
→ 任一異常→TYPE-8M send_meta_alert；Redis去重1h
