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. Domain.String returns "Person", "Group", "Org" for standard DCE domains and formatted fallback for custom values
  2. UUID.Domain returns Person, Group, and Org domain for Version 2 DCE security UUIDs
  3. UUID.ID returns the 32-bit local execution environment identifier embedded in Version 2 DCE security UUID
  4. UUID.Domain and UUID.ID correctly decode domain byte and big-endian 32-bit ID from arbitrary UUID values
  5. uuid.Nil returns Domain(0) for UUID.Domain and 0 for UUID.ID
