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.NewUUID generates RFC 4122 version 1 UUID with valid timestamp and node components
- uuid.FromBytes validates 16-byte slice length and converts to UUID without errors
- uuid.ParseBytes parses byte representations and validates format
- uuid.MustParse returns parsed UUID on valid input and panics on invalid input
- uuid.NullUUID handles database nullability with sql.Scanner and driver.Valuer implementations
