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.Sum64 returns consistent 64-bit hash for byte slice
- xxhash.Sum64String produces identical hash to Sum64 on matching string
- xxhash.Sum64 and Sum64String handle empty input identically
- xxhash.New streaming Digest matches one-shot Sum64 calculation
- xxhash.Digest Reset clears state for subsequent hashing
