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
- v1, v4, and v7 throw RangeError when passed a buffer of length < 16
- v1, v4, and v7 throw RangeError when passed a negative offset or offset + 16 > buffer.length
- v1, v4, and v7 throw Error when passed a random bytes array with length < 16
- v1, v4, and v7 write exactly 16 bytes into a valid buffer slice and return the target buffer without mutating neighboring bytes
- Generated buffer slices parse and stringify into valid UUIDs matching their respective version numbers
