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. MockAgent intercepts requests by origin and consumes each registered interceptor exactly once by default, rejecting subsequent unintercepted requests with MockNotMatchedError when net connect is disabled.
  2. Interceptors configured with .times(n) or .persist() allow repeated matching before being exhausted.
  3. Dynamic reply callbacks in interceptors receive the incoming request options including method, path, headers, and body.
  4. assertNoPendingInterceptors verifies that all registered interceptors were dispatched, throwing an UndiciError if any interceptor remains pending.
