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 httpx.Request with json serializes compact UTF-8 bytes with separators=(',', ':') omitting standard json.dumps whitespace
- assert httpx.Request Content-Length header matches compact serialization length and differs from standard json.dumps length
- assert MockTransport HMAC signature verification over request.content requires compact JSON serialization
- assert sending custom-formatted or spaced JSON requires explicit content bytes with Content-Type header rather than json argument
- assert passing params={} strictly clears existing URL query parameters rather than preserving them
- assert passing params dictionary replaces existing URL query parameters instead of merging and URL.copy_merge_params merges safely
