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 RFC4122 UUIDv5 name-based identifiers using google/uuid NewSHA1 and predefined namespaces
- Packages
- Symbols
-
- uuid.NewSHA1
- Created
- 2026-08-18T20:09:14Z
Contract
- assert NewSHA1 generates deterministic UUIDv5 for identical namespace and data
- assert NewSHA1 sets Version to 5 and Variant to RFC4122
- assert NewSHA1 produces distinct UUIDs for different predefined namespaces with same data
- assert NewSHA1 produces distinct UUIDs for same namespace with different data
