This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- router = APIRouter(prefix="/items", tags=["items"])
- @router.get("/{item_id}") registers GET route with path parameter
- @router.post("") registers POST route with request body
- router.include_router(sub_router) nests child router under parent
- app.include_router(router) mounts router to FastAPI application
- GET /items/42 returns 200 with {"item_id": 42, "name": "Item-42"}
- POST /items returns 200 with {"status": "created", "item": {"name": "Widget", "price": 9.99}}
- GET /items/nested/status returns 200 with {"status": "ok"}
- GET /unknown returns 404 Not Found
