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
- xxhash.Sum64String computes the 64-bit xxHash checksum of a string matching xxhash.Sum64 of the equivalent byte slice
- xxhash.Sum64String produces deterministic non-zero checksum for non-empty string and distinct hashes for distinct string inputs
- xxhash.Sum64String correctly computes the hash of an empty string
