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.

Case
HOW- Goal
- Generate deterministic name-based UUIDv3 and UUIDv5 with google/uuid
- Packages
- Symbols
-
- uuid.NewMD5
- uuid.NewSHA1
- Created
- 2026-08-18T20:14:53Z
Contract
- generate deterministic UUIDv3 using uuid.NewMD5 and assert Version is 3 and Variant is RFC4122
- generate deterministic UUIDv5 using uuid.NewSHA1 and assert Version is 5 and Variant is RFC4122
- assert uuid.NewMD5 and uuid.NewSHA1 match RFC 4122 Appendix B test vectors for DNS namespace
- assert distinct namespaces produce distinct UUIDs for the same name
