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
- A cross-origin JSON GET with an untrusted Origin returns 200 because JsonCsrf defers to HttpOrigin while HttpOrigin treats GET as safe
- The same Origin-bearing GET also returns 200 through the default Rack::Protection stack backed by Rack::Session::Cookie
- A JSON GET with an untrusted Referer and no Origin is rejected with 403 by JsonCsrf
- A POST with an untrusted Origin is rejected with 403 by HttpOrigin
