Sample

Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures.
Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments.

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
