```

## Features

### Core

- **CRUD**: Generic async CRUD operations with `CrudFactory`, built-in search with relationship traversal
- **Database**: Session management, transaction helpers, table locking, and polling-based row change detection
- **Dependencies**: FastAPI dependency factories (`PathDependency`, `BodyDependency`) for automatic DB lookups from path or body parameters
- **Fixtures**: Fixture system with dependency management, context support, and pytest integration
- **Standardized API Responses**: Consistent response format with `Response`, `PaginatedResponse`, and `PydanticBase`
- **Exception Handling**: Structured error responses with automatic OpenAPI documentation
- **Logging**: Logging configuration with uvicorn integration via `configure_logging` and `get_logger`

### Optional

- **CLI**: Django-like command-line interface with fixture management and custom commands support
- **Metrics**: Prometheus metrics endpoint with provider/collector registry
- **Pytest Helpers**: Async test client, database session management, `pytest-xdist` support, and table cleanup utilities
