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 UUID v5 using NewSHA1

- uuid.NewSHA1
- Created
- 2026-08-19T03:34:12Z
Contract
- uuid.NewSHA1 generates a valid version 5 UUID with RFC4122 variant from namespace and data
- uuid.NewSHA1 is deterministic producing identical UUID for identical namespace and data
- uuid.NewSHA1 generates distinct UUIDs for different data within the same namespace
- uuid.NewSHA1 matches RFC 4122 name-based v5 UUID test vector for DNS namespace
