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. MIT-0

Contract

  1. uuid.NewMD5 generates deterministic UUID v3 from namespace and data bytes
  2. uuid.NewMD5 produces identical UUID across multiple calls with identical inputs
  3. uuid.NewMD5 produces distinct UUIDs for different namespaces or different data
  4. uuid.NewMD5 returns a UUID with Version 3 and RFC4122 variant
  5. uuid.NewMD5 handles empty data byte slice without error
