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. guid.NewV4 generates RFC 4122 version 4 pseudorandom GUIDs with correct version and variant bits
  2. guid.FromString and guid.GUID.String parse and format canonical GUID string representations
  3. guid.NewV5 generates deterministic RFC 4122 version 5 GUIDs from namespace and name bytes via SHA-1
  4. guid.GUID.ToArray and guid.FromArray serialize and deserialize 16-byte big-endian binary arrays
  5. guid.GUID.ToWindowsArray and guid.FromWindowsArray serialize and deserialize Windows mixed-endian byte layouts
  6. guid.GUID.MarshalText and guid.GUID.UnmarshalText support text encoding interfaces
