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
- Show that `AuthenticityToken` defaults to global scope and is route-agnostic unless path and method are provided.
- Symbols
-
- Rack::Protection::AuthenticityToken.token
- Environment
- ruby
- Created

Contract
- Leaving `path` and `method` unspecified when calling `Rack::Protection::AuthenticityToken.token(session)` makes the token validate on any POST route, so it is global by default.
- assert repeated calls to `Rack::Protection::AuthenticityToken.token(session)` return different masked values for the same session, proving masking randomness and not a static raw token cache.
- assert a path-scoped token generated with `path` and `method` is rejected on a different path.
