## 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>

## ADDED Requirements
|
|
|
|
### Requirement: Comprehensive API Rate Limiting
|
|
The system SHALL enforce rate limits on all sensitive API endpoints to prevent abuse and ensure service availability.
|
|
|
|
#### Scenario: Task creation rate limit exceeded
|
|
- **WHEN** user exceeds 60 task creation requests per minute
|
|
- **THEN** system returns 429 Too Many Requests
|
|
- **THEN** response includes Retry-After header
|
|
|
|
#### Scenario: Report generation rate limit exceeded
|
|
- **WHEN** user exceeds 5 report generation requests per minute
|
|
- **THEN** system returns 429 Too Many Requests
|
|
- **THEN** response includes rate limit headers
|
|
|
|
#### Scenario: Rate limit headers provided
|
|
- **WHEN** user makes any rate-limited API request
|
|
- **THEN** response includes X-RateLimit-Limit header
|
|
- **THEN** response includes X-RateLimit-Remaining header
|
|
- **THEN** response includes X-RateLimit-Reset header
|
|
|
|
#### Scenario: Rate limit window reset
|
|
- **WHEN** rate limit window expires
|
|
- **THEN** user can make requests again up to the limit
|
|
- **THEN** X-RateLimit-Remaining resets to maximum
|
