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. mimicResponse(fromStream, toStream) copies HTTP response properties including statusCode, statusMessage, headers, and url from fromStream to toStream
  2. mimicResponse(fromStream, toStream) returns the destination toStream instance
  3. mimicResponse(fromStream, toStream) does not overwrite properties already existing on toStream
  4. mimicResponse(fromStream, toStream) throws an Error if toStream has autoDestroy enabled
  5. mimicResponse(fromStream, toStream) forwards getters and setters between fromStream and toStream
  6. mimicResponse(fromStream, toStream) propagates aborted event from fromStream to destroy toStream
