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.UUID Value returns canonical 36-character string representation as driver.Value
  2. uuid.UUID Scan populates UUID from valid 36-character string
  3. uuid.UUID Scan populates UUID from valid 16-byte slice
  4. uuid.UUID Scan returns no error when scanning nil
  5. uuid.UUID Scan returns error for unsupported types or malformed input
  6. uuid.UUID URN returns standard urn:uuid: prefixed canonical string
