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
- httpx.Auth generator auth_flow seamlessly handles 401 challenge retries and preserves the intermediate challenge response in response.history.
- httpx.Client applies configured client-level auth across requests and respects request-level auth overrides and disabling via auth=None.
- httpx.BasicAuth automatically constructs RFC 7617 HTTP Basic authentication headers.
- httpx.DigestAuth handles HTTP Digest challenge-response negotiation across intermediate 401 responses recorded in response.history.
- httpx.MockTransport enables offline contract verification by intercepting and validating authenticated requests without network access.
