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. uuid.NewDCEPerson generates a valid DCE Security (version 2) UUID for Person domain with RFC4122 variant
  2. uuid.NewDCEGroup generates a valid DCE Security (version 2) UUID for Group domain with RFC4122 variant
  3. uuid.Domain constants Person, Group, and Org return expected string representations from String method
  4. UUID.Domain and UUID.ID methods extract domain and principal identifier from DCE Security UUID
  5. uuid.NewDCESecurity generates version 2 UUID preserving custom domain and identifier
  6. uuid.Parse round-trips DCE Security UUID strings preserving Domain and ID
