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 passing raw HTTP header names in the third argument leaves them un-prefixed in env rather than transforming to HTTP_ CGI keys
- assert session header helper transforms names to HTTP_ CGI keys and persists them across subsequent requests until explicitly cleared
- assert posting a raw String body defaults Content-Type to application/x-www-form-urlencoded and form-parses the payload unless overridden
- assert UploadedFile wrapping a StringIO requires original_filename as a keyword argument and transforms params into multipart symbol-keyed Hashes
- assert follow_redirect raises on non-redirects, converts 302 to GET with empty params, and preserves 307 request method and params
- assert cookies without an explicit domain match only the exact host and expired cookies are omitted from subsequent requests
