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. first(pairs, listener) invokes listener with emitted event name, emitter, and arguments when the first event fires
  2. first(pairs, listener) automatically cleans up all event listeners across all tracked emitters once an event has fired
  3. first(pairs, listener) invokes listener with error when an error event fires on any emitter
  4. thunk.cancel() removes all attached listeners from all emitters and prevents callback execution
  5. first(pairs) without initial callback returns a thunk function to attach a listener
