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.prototype defines core event emitter methods and instance prototype chain
  2. Subclasses extending EventEmitter inherit prototype methods and manage events
  3. Prototypal objects inheriting EventEmitter.prototype auto-initialize lazy event state
  4. Listener registration and removal prototype methods return the instance for method chaining
  5. listeners returns listener descriptor tuples while rawListeners returns unwrapped handler functions
  6. newListener and removeListener lifecycle events are emitted during prototype mutation methods
  7. removeAllListeners clears specified event or all events emitting removeListener hooks
  8. getMaxListeners and setMaxListeners interact with instance and default settings
  9. emit triggers registered error listeners synchronously with error payload
