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. exitHook registers exit handlers and initializes standard process event hooks
  2. hookEvent and unhookEvent dynamically manage custom process lifecycle events
  3. hookedEvents returns a list of all currently registered process event names
  4. uncaughtExceptionHandler registers error handlers for uncaught exceptions
  5. unhandledRejectionHandler registers error handlers for unhandled promise rejections
  6. forceExitTimeout configures timeout duration for asynchronous exit handlers
