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
- express() creates application instance with routing and HTTP methods
- express.json() parses JSON request bodies into req.body
- express.urlencoded({ extended: false }) parses URL-encoded form bodies into req.body
- req.params and req.query extract route path parameters and query strings
- express.Router() mounts modular sub-application route handlers
- Express 5 handles async route handlers and forwards rejected promise errors to error middleware
- custom 4-argument error middleware handles application errors and returns error response
