# Phase 10 Plan 01: Config Backup Audit Events Summary
|
|
|
|
**Four audit event types (created, skipped_duplicate, diff_generated, manual_trigger) wired into config backup operations with try/except safety and 4 passing tests**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 3 min
|
|
- **Started:** 2026-03-13T04:43:11Z
|
|
- **Completed:** 2026-03-13T04:46:04Z
|
|
- **Tasks:** 2
|
|
- **Files modified:** 4
|
|
|
|
## Accomplishments
|
|
- Added audit logging to all 4 config backup operations: snapshot creation, deduplication skip, diff generation, and manual backup trigger
|
|
- All log_action calls follow project pattern: try/except wrapped, fire-and-forget, with tenant_id, device_id, action, resource_type, and details
|
|
- 4 new tests verify correct audit action strings are emitted, all 17 tests pass (4 new + 13 existing)
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Add audit event emission to snapshot subscriber, diff service, and backup trigger endpoint** - `1a1ceb2` (feat)
|
|
2. **Task 2: Add tests verifying audit events are emitted** - `fb91fed` (test)
|
|
|
|
## Files Created/Modified
|
|
- `backend/app/services/config_snapshot_subscriber.py` - Added config_snapshot_created and config_snapshot_skipped_duplicate audit events
|
|
- `backend/app/services/config_diff_service.py` - Added config_diff_generated audit event after diff INSERT
|
|
- `backend/app/routers/config_backups.py` - Added config_backup_manual_trigger audit event on manual trigger success
|
|
- `backend/tests/test_audit_config_backup.py` - 4 tests verifying all audit event types are emitted
|
|
|
|
## Decisions Made
|
|
- Module-level import of log_action in snapshot subscriber (no circular dependency risk since audit_service has no deps on snapshot subscriber)
|
|
- Inline import in diff service try block (consistent with existing best-effort pattern and avoids any potential circular import)
|
|
- Inline import in config_backups router try block (same pattern as diff service)
|
|
|
|
## Deviations from Plan
|
|
|
|
None - plan executed exactly as written.
|
|
|
|
## Issues Encountered
|
|
None
|
|
|
|
## User Setup Required
|
|
None - no external service configuration required.
|
|
|
|
## Next Phase Readiness
|
|
- Audit trail complete for all config backup operations
|
|
- All existing tests continue to pass with the new audit imports
