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.FromBytes converts valid 16-byte slice to UUID
  2. uuid.FromBytes returns error when slice length is not 16
  3. uuid.UUID.MarshalText marshals UUID to standard 36-byte canonical string representation
  4. uuid.UUID.UnmarshalText unmarshals valid 36-byte string into matching UUID
  5. uuid.UUID.UnmarshalText returns error when text is invalid UUID format
