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.Validate returns nil for valid UUID string in standard 8-4-4-4-12 format
  2. uuid.Validate returns error for malformed UUID string with invalid length or characters
  3. uuid.ParseBytes parses byte slice of valid UUID string and returns matching UUID struct
  4. uuid.ParseBytes returns error and Nil UUID when given invalid byte slice
  5. uuid.ParseBytes parses 32-character hex byte slice without dashes successfully
