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
- Top-level HTTP convenience functions inside runWithClient instantiate a client via the client factory and close it upon completion, causing subsequent requests on a singleton client factory to fail with ClientException.
- Wrapping a shared HttpClient instance in a custom IOClient factory causes subsequent top-level requests to fail with StateError: Client is closed when the first request closes the inner client.
- Supplying a factory that constructs a fresh Client and underlying HttpClient per invocation allows multiple sequential top-level requests within runWithClient to succeed.
