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. Readable stream emits data and end events when chunks are pushed and ended with null
  2. Readable class can be subclassed overriding _read to push items to the stream
  3. Readable stream supports async iteration yielding each pushed chunk in order
  4. Readable.from static method creates a readable stream from an iterable collection
  5. Readable stream supports flow control with pause and resume and reflects state via Readable.isPaused
  6. Readable stream supports unshift to prepend data back to the read queue
  7. Readable stream supports open lifecycle hook for asynchronous initialization before reading
  8. Readable stream supports map option to transform items during streaming
  9. Readable stream supports pull-based consumption using readable event and read method
  10. Readable stream emits error and close events when destroyed with an error
