Incident API 整合測試
=======================
打真實 API 端點 (https://awoooi.wooo.work)，使用真實 DB

建立時間: 2026-04-04 (台北時區)
建立者: Claude Code (整合測試 Phase 1)

規則:
- 使用 httpx 打真實 HTTPS 端點
- 禁止 Mock
- 不依賴特定資料存在 (resilient assertions)

測試覆蓋:
- GET /api/v1/health — API 健康確認
- GET /api/v1/knowledge — 知識庫列表/搜尋
- GET /api/v1/monitoring/status — 監控工具狀態

注意: GET /api/v1/incidents 不在此測試
  原因: 該端點觸發 AI 決策生成 (LLM 呼叫)，回應時間 30s+，
  不適合整合測試。應使用 smoke_test_alert_chain.py 驗證。
