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

建立時間: 2026-04-09 (台北時區)
建立者: Claude Sonnet 4.6 (B5 整合測試)

覆蓋:
- GET /api/v1/drift/reports — 列出漂移報告（DB 持久化驗證）
- POST /api/v1/drift/internal/scan — 觸發掃描（CronJob endpoint）
- 驗證 DB 持久化：scan 後 reports 列表有新資料
