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. getStream returns a Promise that resolves to the full string contents of a stream
  2. getStream.buffer returns a Promise that resolves to a Buffer with concatenated stream chunks
  3. getStream.array returns a Promise that resolves to an array of items for an object-mode stream
  4. getStream with maxBuffer option rejects with getStream.MaxBufferError when stream data exceeds limit
  5. getStream rejects when the readable stream emits an error event
