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.

- httpx.HTTPTransport
- httpx.Client

- httpx.ConnectError

Contract
- assert httpx.Client does not accept retries kwarg, raising TypeError
- assert httpx.HTTPTransport retries default to 0 and must be explicitly configured
- assert HTTPTransport(retries=N) retries ConnectError and ConnectTimeout exactly N times (N+1 total attempts)
- assert HTTPTransport(retries=N) never retries ReadTimeout, ReadError, or HTTP 5xx responses
- assert Timeout four fields (connect, read, write, pool) map to transport extensions and specific TimeoutException subclasses
- assert application-level status and read retries require custom BaseTransport wrapping
