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. v1ToV6 losslessly reorders a UUIDv1 into a sortable UUIDv6 by rearranging timestamp fields into big-endian order and setting version 6, while v6ToV1 restores the original UUIDv1.
  2. v6(options) produces the exact same UUID string as passing v1(options) output into v1ToV6
  3. v1ToV6 and v6ToV1 operate identically on 16-byte Uint8Array buffers and return Uint8Array instances
  4. v1ToV6 and v6ToV1 reject non-UUID string inputs with TypeError('Invalid UUID')
