Implemented first concrete LLM provider following the provider interface pattern.
Implementation:
- OllamaProvider class implementing LlmProviderInterface
- All required methods: initialize(), checkHealth(), listModels(), chat(), chatStream(), embed(), getConfig()
- OllamaProviderConfig extending LlmProviderConfig
- Proper error handling with NestJS Logger
- Configuration immutability protection
Features:
- System prompt injection support
- Temperature and max tokens configuration
- Embedding with truncation control (defaults to enabled)
- Streaming and non-streaming chat completions
- Health check with model listing
Testing:
- 21 comprehensive test cases (TDD approach)
- 100% statement, function, and line coverage
- 86.36% branch coverage (exceeds 85% requirement)
- All error scenarios tested
- Mock-based unit tests
Code Review Fixes:
- Fixed truncate logic to match original LlmService behavior (defaults to true)
- Added test for system prompt deduplication
- Increased branch coverage from 77% to 86%
Quality Gates:
- ✅ All 21 tests passing
- ✅ Linting clean
- ✅ Type checking passed
- ✅ Code review approved

Implements comprehensive CRUD APIs following TDD principles with 92.44%
test coverage (exceeds 85% requirement).
Features:
- Tasks API: Full CRUD with filtering, pagination, and subtask support
- Events API: Full CRUD with recurrence support and date filtering
- Projects API: Full CRUD with task/event association
- Authentication guards on all endpoints
- Workspace-scoped queries for multi-tenant isolation
- Activity logging for all operations (CREATED, UPDATED, DELETED, etc.)
- DTOs with class-validator validation
- Comprehensive test suite (221 tests, 44 for new APIs)
Implementation:
- Services: Business logic with Prisma ORM integration
- Controllers: RESTful endpoints with AuthGuard
- Modules: Properly registered in AppModule
- Documentation: Complete API reference in docs/4-api/4-crud-endpoints/
Test Coverage:
- Tasks: 96.1%
- Events: 89.83%
- Projects: 84.21%
- Overall: 92.44%
TDD Workflow:
1. RED: Wrote failing tests first
2. GREEN: Implemented minimal code to pass tests
3. REFACTOR: Improved code quality while maintaining coverage

- Integrated BetterAuth library for modern authentication
- Added Session, Account, and Verification database tables
- Created complete auth module with service, controller, guards, and decorators
- Implemented shared authentication types in @mosaic/shared package
- Added comprehensive test coverage (26 tests passing)
- Documented type sharing strategy for monorepo
- Updated environment configuration with OIDC and JWT settings
Key architectural decisions:
- BetterAuth over Passport.js for better TypeScript support
- Separation of User (DB entity) vs AuthUser (client-safe subset)
- Shared types package to prevent FE/BE drift
- Factory pattern for auth config to use shared Prisma instance
Ready for frontend integration (Issue #6).
