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
