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.NewString generates a valid 36-character UUID string
  2. uuid.Validate validates correct UUID strings and rejects invalid format
  3. uuid.Parse parses UUID strings into UUID values with Version 4 and RFC4122 variant
  4. uuid.FromBytes converts a 16-byte slice to a UUID and rejects invalid lengths
  5. uuid.NewRandom returns a random UUID of Version 4
