```

### Backend Patterns

- **Models**: SQLAlchemy declarative models with relationships
- **Schemas**: Pydantic models for validation (separate from ORM models)
- **Routers**: API endpoints organized by resource (auth, users, projects, etc.)
- **Database**: Dependency injection pattern using `get_db()` generator
- **Auth**: JWT tokens with Bearer authentication, role-based access control
- **CORS**: Configured for localhost:5173 and localhost:5174

## Frontend Architecture (/frontend)

```

├── vite.config.ts   # Vite build configuration
└── package.json     # Node.js dependencies
```

### Frontend Patterns

- **Components**: Feature-based organization, composition API with `<script setup>`
- **Stores**: Pinia stores using composition API pattern (ref, computed)
- **Services**: Axios-based API clients with centralized error handling
- **Routing**: Nested routes for project details, meta-based auth guards
- **Auth**: Token stored in localStorage, axios interceptors for auth headers
- **State**: Pinia for global state, local refs for component state
- **Styling**: Tailwind utility classes, shadcn-vue for consistent UI

## Key Conventions

- **Enums**: Shared between backend (Python Enum) and frontend (TypeScript types)
- **API Prefix**: All API calls use `/api` prefix (configured in Vite proxy)
- **File Naming**: PascalCase for components/views, camelCase for services/utils
- **Database**: SQLite with auto-generated tables via SQLAlchemy metadata
