||
## Phase 3: Append-Only Enforcement
|
||
|
||
### 3.1 Database Triggers
|
||

|
||
- [x] 3.1.2 建立 prevent_audit_delete trigger (需手動執行於 production)
|
||
- [x] 3.1.3 新增 migration 包含 triggers
|
||

||
### 3.2 Verification
|
||

||
## Notes
|
||
|
||
- **Triggers**: MySQL triggers 需要 SUPER 權限才能在有 binary logging 的環境建立。Migration 會嘗試建立 trigger，失敗時記錄警告。Production 環境需手動執行 trigger SQL。
|
||
- **Tests**: 新增 11 個軟刪除相關測試於 tests/test_soft_delete.py
|
||
- **Total Tests**: 153 tests passing
