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
- onExit registers an exit callback and returns an unregister function
- calling the returned unregister function prevents the exit callback from firing
- onExit throws AssertionError when a non-function callback is passed
- onExit callback receives the numeric exit code when process.exit is called
- onExit callback receives exit code 0 when the Node.js event loop terminates naturally
- onExit callback receives the signal name when the process receives a termination signal
- onExit with alwaysLast option executes after standard exit listeners
- signals export provides an array of standard POSIX termination signal names
- load and unload functions control the lifecycle of process exit listeners
