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 restore_state rolls back last_request, last_response, and cookie_jar but leaves mutated session headers in @env to leak into subsequent requests, while non-GET methods encode params into the request body rather than the query string
- assert non-GET verbs like DELETE and HEAD encode parameter hashes as form bodies in rack.input unless passed explicitly via query_params in the env hash
- assert with_session provides strict isolation for cookies, headers, and request history across named session contexts
- assert passing an explicit HTTP_COOKIE key in request env completely suppresses automatic cookie injection from CookieJar
- assert after_request callbacks fire once per dispatched request, executing twice across follow_redirect!
- assert basic_authorize persists HTTP Basic credentials in session headers across subsequent requests until explicitly cleared
