## Security Enhancements (P0) - Add input validation with max_length and numeric range constraints - Implement WebSocket token authentication via first message - Add path traversal prevention in file storage service ## Permission Enhancements (P0) - Add project member management for cross-department access - Implement is_department_manager flag for workload visibility ## Cycle Detection (P0) - Add DFS-based cycle detection for task dependencies - Add formula field circular reference detection - Display user-friendly cycle path visualization ## Concurrency & Reliability (P1) - Implement optimistic locking with version field (409 Conflict on mismatch) - Add trigger retry mechanism with exponential backoff (1s, 2s, 4s) - Implement cascade restore for soft-deleted tasks ## Rate Limiting (P1) - Add tiered rate limits: standard (60/min), sensitive (20/min), heavy (5/min) - Apply rate limits to tasks, reports, attachments, and comments ## Frontend Improvements (P1) - Add responsive sidebar with hamburger menu for mobile - Improve touch-friendly UI with proper tap target sizes - Complete i18n translations for all components ## Backend Reliability (P2) - Configure database connection pool (size=10, overflow=20) - Add Redis fallback mechanism with message queue - Add blocker check before task deletion ## API Enhancements (P3) - Add standardized response wrapper utility - Add /health/ready and /health/live endpoints - Implement project templates with status/field copying ## Tests Added - test_input_validation.py - Schema and path traversal tests - test_concurrency_reliability.py - Optimistic locking and retry tests - test_backend_reliability.py - Connection pool and Redis tests - test_api_enhancements.py - Health check and template tests Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

# Tasks: Add Backend Reliability Improvements
|
|
|
|
## 1. Database Connection Pool
|
|
- [x] 1.1 Add pool_size=10 configuration
|
|
- [x] 1.2 Add max_overflow=20 configuration
|
|
- [x] 1.3 Add pool_timeout=30 configuration
|
|
- [x] 1.4 Add environment variable overrides for pool settings
|
|
- [x] 1.5 Log connection pool statistics periodically
|
|
|
|
## 2. Redis Fallback Mechanism
|
|
- [x] 2.1 Create in-memory queue for failed Redis publishes
|
|
- [x] 2.2 Implement background retry for queued messages
|
|
- [x] 2.3 Add max queue size limit to prevent memory issues
|
|
- [x] 2.4 Log Redis failures and recovery events
|
|
|
|
## 3. Blocker Deletion Check
|
|
- [x] 3.1 Add check for unresolved blockers before task deletion
|
|
- [x] 3.2 Return warning response with blocker count
|
|
- [x] 3.3 Add force_delete parameter to bypass check
|
|
- [x] 3.4 Auto-resolve blockers when force deleting
|
|
|
|
## 4. NAS Storage Validation
|
|
- [x] 4.1 Validate UPLOAD_DIR path exists on startup
|
|
- [x] 4.2 Check write permissions on storage directory
|
|
- [x] 4.3 Log warning if using local storage instead of NAS
|
|
- [x] 4.4 Add health check endpoint for storage status
|
|
|
|
## 5. Testing
|
|
- [x] 5.1 Test under connection pool exhaustion
|
|
- [x] 5.2 Test Redis disconnect and recovery
|
|
- [x] 5.3 Test blocker deletion scenarios
