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.Client with MockTransport executes synchronous HTTP requests, applies headers and query params, and decodes JSON responses offline.
- httpx.AsyncClient with MockTransport executes asynchronous HTTP requests, supports async context managers, and streams response content via aiter_bytes.
- httpx request and response event hooks execute synchronously during the request lifecycle to inspect or modify HTTP traffic.
- httpx.URL parses URIs, exposes path and query components, and performs RFC 3986 reference resolution via join.
- Response.raise_for_status raises httpx.HTTPStatusError on 4xx/5xx responses without consuming or invalidating response content.
- httpx.Headers maintains case-insensitive header lookup and preserves discrete header formatting.
