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.NewMD5 generates deterministic UUID v3 from namespace and data bytes
  2. uuid.NewMD5 produces identical UUID across multiple calls with identical inputs
  3. uuid.NewMD5 produces distinct UUIDs for different namespaces or different data
  4. uuid.NewMD5 returns a UUID with Version 3 and RFC4122 variant
  5. uuid.NewMD5 handles empty data byte slice without error
