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.NewRandomFromReader generates a valid UUID v4 using crypto/rand.Reader
- uuid.NewRandomFromReader returns a UUID with Version 4 and RFC4122 variant
- uuid.NewRandomFromReader generates deterministic UUID from a custom byte reader with version and variant bits applied
- uuid.NewRandomFromReader returns an error and Nil UUID when reader returns EOF before reading 16 bytes
- uuid.NewRandomFromReader returns an error when underlying reader returns an error
