Code Quality Assessment

Test Coverage

• Overall: Fair — unit tests exist for Core and Availability modules
• Unit Tests: Present for Core.Tests and Modules.Availability.Tests
• Integration Tests: Not observed in current structure
• Frontend Tests: None (example app has no test files)

Code Quality Indicators

• Linting: Not explicitly configured (no .editorconfig or eslint config seen in backend; frontend likely uses Vite defaults)
• Code Style: Consistent — clean C# with XML doc comments on public interfaces and entities
• Documentation: Good for core interfaces and entities (XML doc comments); controllers have minimal comments
• Naming: Follows .NET conventions (PascalCase classes/methods, camelCase parameters)

Technical Debt

• Auth context in example React app uses localStorage for user state (security concern — no httpOnly cookies)
• Example app auth-context simulates login locally without real API calls (will need to be replaced with actual API integration)
• No CORS configuration confirmed in backend (needs verification for SPA integration)
• AvailabilityController.UpdateStatus uses a direct service cast (as PersistentAvailabilityService) which couples controller to implementation
• No OpenAPI/Swagger spec currently integrated (would help frontend integration)

Patterns and Anti-patterns

Good Patterns

• Module pattern provides clear separation of concerns between features
• JWT refresh token rotation is properly implemented
• Authorization policies are well-defined (OwnerOnly, AdminOnly)
• EF Core used consistently for persistence
• Service interfaces (IAuthService, IInvitationService, ISetupService) for testability

Anti-patterns

• Direct implementation cast in AvailabilityController (should use extended interface instead)
• Example React app uses localStorage-based auth (acceptable for prototype, not production)
• Example React app auth-context hardcodes mock users (must be replaced with real API calls)
