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.

Contract
- emitter.on registers an event listener and returns the emitter instance for chaining
- emitter.on triggers the listener synchronously with all passed arguments when the event is emitted
- emitter.on preserves the EventEmitter instance as this context within listener functions
- emitter.on emits a newListener event before adding the listener to the emitter
- emitter.on appends listeners in registration order and supports multiple listeners for the same event
- EventEmitter.on static helper returns an async iterable yielding argument arrays for emitted events
- EventEmitter.on queues emitted events until consumed by next
- EventEmitter.on respects AbortSignal and rejects with OPERATION_ABORTED when aborted
- EventEmitter.on cleans up its internal listeners when return is called on the iterator
- EventEmitter.on rejects iterator promises when the emitter emits an error event
