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. teex splits a readable stream into two readable streams by default
  2. teex splits a readable stream into a specified number of fork streams
  3. teex streams receive all data emitted by the source stream in the same order
  4. teex propagates the end event of the source stream to all branched streams
  5. teex destroys all branched streams with error when source emits an error
  6. teex pauses and resumes source stream based on downstream consumption
  7. splitStream and teePair helper functions wrap teex with expected signatures
