Python Web

Load python3-core for standing defaults. Load python3-typing for request/response modeling. Load python3-testing for endpoint and auth tests.

Quality Checklist

Route handlers contain NO business logic — only validation, delegation, response mapping
No framework objects (Request, Response, ORM models) leak into domain layer
model_config = {"strict": True} on all request models
Separate request and response models per endpoint — never reuse ORM models as API schemas
Auth resolved at edge; domain functions receive typed identity, never raw tokens
Domain exceptions mapped to HTTP status codes at boundary, not scattered through handlers
Async handlers use httpx.AsyncClient — never requests (blocks event loop)
Background tasks hold no references to request-scoped objects
