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.

Contract
- 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.
- v6(options) produces the exact same UUID string as passing v1(options) output into v1ToV6
- v1ToV6 and v6ToV1 operate identically on 16-byte Uint8Array buffers and return Uint8Array instances
- v1ToV6 and v6ToV1 reject non-UUID string inputs with TypeError('Invalid UUID')
