Some checks failed
run-migration / migrate (push) Failing after 22s
Deploy Alert Rules / Deploy Prometheus Alert Rules (push) Successful in 53s

CD Pipeline / build-and-deploy (push) Has been cancelled
Ansible Lint / lint (push) Has been cancelled

【根因鏈修復】
MCP Provider bugs → PreDecisionInvestigator 失敗 → Agent Debate 無上下文
→ LLM 逾時 → description="待分析" → ADR-091 鐵閘攔截 → tg_sent 未設
→ W-2 Watchdog 誤報「靜默故障」

【六大修復】
1. MCP Provider 三蟲修復
   - ssh_provider: asyncssh.run() → conn.run()
   - prometheus_provider: KeyError 'query' → .get() 容錯
   - k8s_provider: 空 pod_name → 早返回錯誤字典

2. Agent Debate / 決策品質
   - decision_manager: 逾時降級文字改為明確描述(繞過 ADR-091 鐵閘)
   - intent_classifier: LLM 逾時降級至關鍵字分類(非 None)

3. Watchdog 誤報修復(ADR-092 B3)
   - W-2: tg_sent Redis TTL → telegram_message_id IS NULL(DB 真值)
   - W-5 新增: suggested_action IN 空/待分析/NO_ACTION + tg_id IS NULL
   - approval_timeout_resolver: 60min → 15min,batch 50 → 200

4. Config Drift 自動化
   - drift_adopt_service: auto_adopt_if_safe() 六條件安全閘
   - drift.py: 背景任務先嘗試自動採納再發人工 Telegram 卡片

5. Playbook 飛輪穩定
   - playbook_seed_service: 修復幂等性(deprecated 不視為缺失)
   - playbook_evolver: 只載 DRAFT+APPROVED(非全部 294 筆)

6. 可觀測性
   - alert_rule_engine: auto_rule 結構化日誌 + Redis 計數器(pipeline)
   - auto_approve: reject 原因 Redis 計數器
   - heartbeat_report_service: 新增「⚙️ 自動化統計(今日)」區塊
