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.

Case
HOW- Goal
- generate deterministic name-based UUID v5 with github.com/google/uuid
- Packages
- Symbols
-
- uuid.NewSHA1
- Created
- 2026-08-18T20:26:07Z
Contract
- uuid.NewSHA1 generates deterministic UUID v5 from namespace and data bytes
- uuid.NewSHA1 produces identical UUID across multiple calls with identical inputs
- uuid.NewSHA1 produces distinct UUIDs for different namespaces or different data
- uuid.NewSHA1 returns a UUID with Version 5 and RFC4122 variant
- uuid.NewSHA1 handles empty data byte slice without error
