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. Worker initializes worker pool with worker_threads and executes synchronous exported functions
  2. Worker executes asynchronous exported functions and resolves returned Promises
  3. Worker executes batch tasks in parallel across worker instances and shuts down cleanly with Worker.end
  4. Worker propagates synchronous exceptions thrown within worker tasks as rejected Promises
  5. Worker executes setup lifecycle hook with setupArgs during worker initialization
  6. Worker supports forked child process mode and terminates with Worker.end
