_write_execution_result_to_km() 強化： - 依 approval.requested_by 區分 [自動修復]/[人工修復] - 從關聯 Incident 提取 alertname / alert_category / affected_services - Category 從硬編 "execution_result" 改為真實 alert_category - Tags: auto_executed/human_approved + success/failure + alert_category - Title 含 alertname，提升 RAG 檢索精準度 - created_by 依模式標記 auto_execute / approval_execution 驗證（2026-04-14 DB 查詢）： - 現有 KM 確實有寫入（approval_execution 建立者） - 但標題全是「[執行記錄] ❌ kubectl rollout restart deployment/xxx」 - Category 硬編 execution_result，tags 只有 execution/execution_failed - 本次改造後 KM 將具備完整上下文供下次 RAG 檢索 建立: 2026-04-14 台北時間 Claude Sonnet 4.6（MASTER 藍圖 BP-1 B.1 精修） Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>

Approval Execution Service - Phase 16 R4.2 瘦身 Router 抽取
|
||
============================================================
|
||
|
||
從 approvals.py 抽取執行編排邏輯，整合:
|
||
- OperationParser: 解析操作類型
|
||
- K8s Executor: 執行 K8s 操作
|
||
- ApprovalDBService: 更新狀態
|
||
- TimelineService: 記錄事件
|
||
- NotificationManager: 發送通知
|
||
- Phase 7.6: Playbook 自動萃取
|
||
|
||
版本: v1.2
|
||
建立: 2026-03-25 (台北時區)
|
||
更新: 2026-03-26 (Phase 7.6 自動萃取)
|
||

重試設計 (ADR-076):
|

- MAX_RETRY = 2 次（共最多 3 次嘗試）

- RETRY_DELAY_SECONDS = 30 秒
|
||
- 只重試瞬態錯誤（connection refused, timeout, i/o error 等）
|
||
- 永久性錯誤（not found, permission denied, already exists）不重試
