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
- assert uvicorn.__version__ == '0.52.1'
- uvicorn.Config initializes with specified host, port, log_level, and lifespan configuration and resolves ASGI application
- uvicorn.Config configures HTTP protocol handler and SSL status
- uvicorn.Server initializes with Config instance and manages server lifecycle state
- uvicorn.Server starts HTTP server on ephemeral port, handles ASGI request, and terminates upon should_exit
