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.SetNodeInterface with empty string resets to default interface selection and returns true
  2. uuid.SetNodeInterface returns false for non-existent network interface names
  3. uuid.NodeInterface returns user when node ID is set via SetNodeID
  4. uuid.SetNodeInterface configures node ID from named network interface hardware address
  5. uuid.NewUUID generates valid Version 1 UUID containing configured interface or node ID
