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.Router() creates modular route handlers for HTTP methods
- router.use() applies router-level middleware to scoped sub-paths
- router.route() chains multiple HTTP method handlers on a single route path
- router.param() intercepts and processes URL path parameters
- express.Router({ mergeParams: true }) propagates parent route parameters to nested routers
- express.Router({ caseSensitive: true }) enforces strict case sensitivity on routes
- express.Router in Express 5 catches async handler exceptions and propagates to error middleware
