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 uuid.NewDCESecurity creates a Version 2 UUID with RFC4122 variant for specified domain and local ID
  2. assert uuid.NewDCEPerson creates a Version 2 UUID with Person domain and the caller's POSIX UID
  3. assert uuid.NewDCEGroup creates a Version 2 UUID with Group domain and the caller's POSIX GID
  4. assert UUID.Domain returns the expected Domain constant (Person, Group, Org) and UUID.ID returns the embedded 32-bit local ID
  5. assert UUID.Time extracts timestamp and UUID.NodeID returns valid 6-byte node identifier
