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

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. UUID.MarshalText encodes UUID into standard 36-byte UTF-8 string representation without error
  2. UUID.UnmarshalText decodes standard 36-byte UUID text into matching UUID value
  3. UUID.UnmarshalText decodes 32-character hex and URN formatted byte slices
  4. UUID.UnmarshalText returns error for invalid format or invalid length byte slices
  5. UUID.MarshalText and UnmarshalText support uuid.Nil and round trip lossless conversion
