# Tasks: Enable Audit Logging

## 1. Helper Utilities
- [x] 1.1 Create helper function to extract client info (IP, user agent) from FastAPI Request

## 2. Authentication Events
- [x] 2.1 Log `auth_login` on successful/failed login in auth.py
- [x] 2.2 Log `auth_logout` on logout in auth.py
- [ ] 2.3 Log `auth_token_refresh` on token refresh (deferred - low priority)

## 3. Task Events
- [ ] 3.1 Log `task_create` when task is created (deferred - covered by file_upload)
- [ ] 3.2 Log `task_process` when task processing starts (deferred - background task)
- [ ] 3.3 Log `task_complete` when task completes (deferred - background task)
- [x] 3.4 Log `task_delete` when task is deleted

## 4. Admin Events
- [x] 4.1 Log `admin_cleanup` when manual cleanup is triggered
- [ ] 4.2 Log `admin_view_users` when admin views user list (deferred - low priority)

## 5. File Events
- [x] 5.1 Log `file_upload` when file is uploaded

## 6. Testing
- [ ] 6.1 Verify login creates audit log entry
- [ ] 6.2 Verify task operations create audit log entries
- [ ] 6.3 Verify audit logs page shows entries
- [x] 6.4 Test backend module imports

## Notes
- Core audit events implemented: login, logout, task delete, file upload, admin cleanup
- Background task events (task_process, task_complete) deferred - would require significant refactoring
- Low priority admin events deferred for future implementation
