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.New generates a valid version 4 UUID with RFC4122 variant
  2. uuid.Parse and uuid.ParseBytes parse 36-character hyphenated UUID strings and byte slices
  3. uuid.Parse parses 32-character hexadecimal UUID format and URN formatted strings
  4. uuid.Parse and uuid.Validate return errors for malformed or invalid length UUID strings
  5. uuid.FromBytes constructs UUID from 16-byte slice and rejects invalid slice lengths
  6. uuid.Nil represents zero value UUID with Version 0 and Reserved variant
