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.

Case
HOW- Goal
- Detect that missing session state in AuthenticityToken is an exception path instead of a normal 403 defense path.

- Environment

Contract
- assert that `Rack::Protection::AuthenticityToken.new(app).call(Rack::MockRequest.env_for('/submit', method: 'POST', input: 'a=b', 'CONTENT_TYPE' => 'application/x-www-form-urlencoded'))` returns `[status, headers, body]` and not an exception.
- assert that the status from that tuple is exactly 403.
- assert that the body includes `Forbidden` because rejection is handled by `deny` even when session setup is wrong.
