Key Observations

  1. Strong Foundation: The core architecture is well-implemented with proper modules, entities, and page structure.

  2. Recent Progress (October 2025): ✅

    • Photo management system with MinIO integration
    • Comprehensive error code system with multi-language support
    • Redis caching infrastructure
    • Performance monitoring and database optimization
    • Audit logging for compliance

  3. Missing Critical Features: Offline-first functionality, password reset, email verification, and remaining compliance features are the most critical gaps.

  4. AI Needs Work: The AI module exists but lacks safety features, context management, and multi-language support.

  5. Testing Needed: Jest is configured but no tests have been written. This is a significant technical debt.

  6. Accessibility Gaps: No evidence of accessibility testing or screen reader support.

  7. Security Hardening: Basic authentication exists, error handling improved ✅, but still lacks MFA, rate limiting, and comprehensive validation.

Next Steps

  1. Prioritize offline-first implementation - This is documented as a core requirement but not implemented
  2. Add error handling and logging - Critical for production debugging
  3. Implement compliance features - Legal requirement for launch
  4. Write tests - Critical for code quality and maintainability
  5. Add accessibility features - Legal requirement and good practice

Documentation Quality

The documentation is excellent and comprehensive. The main challenge is that the implementation has only completed about 30-40% of the documented features. The project needs focused implementation effort on the critical gaps identified in this document.
