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. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. Router returns a callable dispatch function inheriting from Router prototype
  2. router.use mounts general and path-prefixed middleware executing in registration order
  3. router.get and router.post dispatch to method-specific route handlers matching the URL path
  4. router.route creates chainable HTTP verb handlers on a single path
  5. router.param captures and validates route placeholders before route execution
  6. router handles unmatched routes by delegating to the done callback
  7. router error-handling middleware catches errors propagated via next(err)
  8. sub-routers can be nested using router.use for modular routing
