📝 NOTES​

Key Dependencies:

  • Phase 2 depends on Phase 1 repositories
  • Phase 3 depends on Phase 2 repositories
  • Frontend integration depends on API handlers

Critical Path:

  1. Phase 1 repositories (blocking everything)
  2. Phase 2 repositories (blocking API)
  3. API handlers (blocking frontend)
  4. Frontend integration (final step)

Next Steps:

  1. ✅ Complete Phase 1 models
  2. ✅ Implement base FdbRepository trait
  3. ✅ Implement 5 Phase 1 repositories
  4. ✅ Complete Phase 2 models
  5. ✅ Implement 6 Phase 2 repositories
  6. ⏳ Write tests for Phase 1 & 2
  7. ⏳ Start Phase 3 - Backend API Integration

Last Updated: 2025-10-14 Status: ✅ Phase 1 & 2 Complete - 10 Models, 10 Repositories, 2,860 Lines
