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.ParseBytes parses standard 36-byte hyphenated UUID byte slices
  2. uuid.ParseBytes parses 32-byte hex byte slices without hyphens
  3. uuid.ParseBytes parses 45-byte URN-prefixed UUID byte slices
  4. uuid.ParseBytes parses 38-byte braced UUID byte slices
  5. uuid.ParseBytes produces identical UUID values as uuid.Parse
  6. uuid.ParseBytes returns an error for invalid length or non-hex byte slices
