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. EventEmitter.forward lazily attaches a listener to the source emitter only when a listener is registered on the destination emitter
  2. forwarded events emitted on the source emitter are received by listeners on the destination emitter with original arguments
  3. multiple listeners on the destination emitter share a single forwarding listener on the source emitter
  4. removing all listeners for an event on the destination emitter detaches the forwarding listener from the source emitter
  5. forward supports an array of multiple event names managed independently
  6. forward accepts an optional custom emit function in options to intercept forwarded events
