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
- assert UUID.v5 generates a deterministic RFC4122 v5 UUID string given a name and namespace Buffer
- assert UUID constructor instantiates from a valid UUID string and 16-byte Buffer with correct toString and inspect representation
- assert UUID.check validates string and Buffer UUIDs, identifies nil UUID, and rejects malformed inputs
- assert UUID constructor throws Error on invalid UUID string or invalid Buffer
- assert UUID.parse converts formatted UUID string to 16-byte Buffer matching UUID.OID
