Implements #9, #10
- Team model with workspace membership
- TeamMember model with role-based access (OWNER, ADMIN, MEMBER)
- Row-Level Security policies for tenant isolation on 19 tables
- Helper functions: current_user_id(), is_workspace_member(), is_workspace_admin()
- Developer utilities in src/lib/db-context.ts for easy RLS integration
- Comprehensive documentation in docs/design/multi-tenant-rls.md
Database migrations:
- 20260129220941_add_team_model: Adds Team and TeamMember tables
- 20260129221004_add_rls_policies: Enables RLS and creates policies
Security features:
- Complete database-level tenant isolation
- Automatic query filtering based on workspace membership
- Defense-in-depth security with application and database layers
- Performance-optimized with indexes on workspace_id
- Add DomainsModule with full CRUD, search, and activity logging
- Add IdeasModule with quick capture endpoint
- Add LayoutsModule for user dashboard layouts
- Add WidgetsModule for widget definitions (read-only)
- Update ActivityService with domain/idea logging methods
- Register all new modules in AppModule
- 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).
