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. finished calls callback with null when a Readable stream completes consumption and closes
  2. finished calls callback with null when a Writable stream writes all chunks, ends, and closes
  3. finished calls callback with null when a Transform stream completes and closes
  4. finished captures stream error and passes the exact error to callback when a stream is destroyed with an error
  5. finished invokes callback immediately with the stream error when called on an already destroyed stream
  6. finished returns a detach function that removes completion listeners and prevents callback invocation
  7. finished with cleanup option true removes all attached close and error event listeners upon completion
