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. assert an into: :self body is a Req.Response.Async tied to the requester pid and enumeration in another process raises RuntimeError
  2. assert the requester can consume the same three queued chunks after the worker fails
  3. assert an unconsumed three-chunk stream leaves three data messages and one done message for its ref in the requester mailbox
  4. assert halting after two chunks drains the remaining messages for that response ref
  5. assert a File stream receives a tested 200 body but a tested 404 body remains buffered and does not create the file
  6. assert an into callback receives both chunks from the tested 500 response
