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
- Req interpolates colon-style and curly-style path parameters with URI encoding while leaving unmatched path segments intact
- assert passing an integer range sets the Range header to bytes=first-last while string ranges pass through unchanged
- assert matching response body SHA-256 succeeds while a mismatched checksum raises Req.ChecksumMismatchError with expected and actual fields
- assert Req.Test stubs handle json helper responses and simulate transport errors when retry is disabled
- assert setting raw: true preserves the unparsed response binary rather than decoding JSON
