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.NewV6 returns non-nil UUID v6 without error
  2. uuid.NewV6 returns UUID with Version 6 and RFC4122 variant
  3. uuid.NewV6 contains extractable time and node ID components
  4. uuid.NewV6 generates time-ordered UUIDs where successive UUIDs have equal or increasing byte order
  5. uuid.Parse successfully parses generated UUID v6 string back to original UUID
  6. uuid.Validate confirms generated UUID v6 string is valid
