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
- createApp configures Hono application with cors middleware supporting wildcard, restricted, and dynamic origin policies
- cors middleware handles preflight OPTIONS requests and sets Access-Control-Allow-Origin header for wildcard origin
- cors middleware enforces restricted origin whitelist with allowed methods, custom headers, credentials, and maxAge
- cors middleware exposes specified custom response headers via Access-Control-Expose-Headers on successful requests
- cors middleware rejects requests from origins outside the configured whitelist
- cors middleware validates dynamic origins using a custom callback function
