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. MethodRouter::merge correctly registers CONNECT route handlers in the connect endpoint slot
  2. Sending a CONNECT request to a merged MethodRouter dispatches to the connect handler and returns 200 OK
  3. Sending an OPTIONS request to a merged MethodRouter retains the options handler response instead of being overwritten by CONNECT
  4. Sending a GET or POST request to the merged MethodRouter correctly routes to their respective handlers with 200 OK
