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. assert NewSHA1 generates deterministic UUIDv5 for identical namespace and data
  2. assert NewSHA1 sets Version to 5 and Variant to RFC4122
  3. assert NewSHA1 produces distinct UUIDs for different predefined namespaces with same data
  4. assert NewSHA1 produces distinct UUIDs for same namespace with different data
