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 requires an absolute worker path upon instantiation
  2. Worker executes exposed module methods in parallel worker threads and returns resolved results
  3. Worker propagates exceptions thrown in worker methods as rejected promises
  4. Worker supports custom sticky routing using computeWorkerKey
  5. Worker provides stdout and stderr readable streams via getStdout and getStderr
  6. Worker supports custom TaskQueue implementations including FifoQueue and PriorityQueue
  7. Worker end gracefully terminates the worker farm and rejects subsequent method calls
