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 NewDCESecurity creates Version 2 UUID with RFC4122 variant for given Domain and ID
  2. assert Domain and ID methods correctly extract embedded domain and local ID from UUIDv2
  3. assert NewDCEPerson creates UUIDv2 with Person domain and current process UID
  4. assert NewDCEGroup creates UUIDv2 with Group domain and current process GID
