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

Contract
- events-universal exports an EventEmitter constructor
- EventEmitter instances register and trigger event listeners with arguments via on and emit
- EventEmitter.once registers one-time event listeners that automatically unregister after invocation
- EventEmitter.removeListener and off remove specific registered listeners
- EventEmitter.removeAllListeners removes all listeners for a given event or all events
- EventEmitter.listenerCount returns the number of registered listeners for an event
- EventEmitter.eventNames returns an array of registered event names
- EventEmitter.prependListener adds listeners to the beginning of the listener array
