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
- uuid.NewV7 generates a valid UUID with version 7 and RFC4122 variant
- uuid.Validate returns nil for valid UUIDv7 string
- uuid.Validate returns an error for invalid UUID strings
- uuid.Parse successfully parses UUIDv7 string into UUID with version 7
- Consecutive uuid.NewV7 calls generate time-ordered UUIDs
