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.NewDCESecurity generates a Version 2 UUID for specified Domain and ID
  2. uuid.NewDCESecurity sets Version 2 and RFC4122 variant and returns specified Domain and ID
  3. uuid.NewDCEPerson generates a Version 2 UUID with Person domain
  4. uuid.NewDCEGroup generates a Version 2 UUID with Group domain
  5. uuid.NewDCESecurity produces a 16-byte UUID that round-trips with String() and Parse()
