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.SetNodeID sets custom node ID and returns true for byte slices of length 6 or greater and false for shorter slices
  2. uuid.NodeID returns the configured 6-byte node ID slice
  3. uuid.SetClockSequence and uuid.ClockSequence configure and retrieve the 14-bit clock sequence
  4. uuid.GetTime returns valid uuid.Time timestamp and clock sequence without error
  5. uuid.NewUUID generates valid RFC 4122 Version 1 time-based UUID with Version 1 and RFC4122 variant
  6. uuid.UUID NodeID and ClockSequence methods extract the configured node ID and clock sequence from generated UUID v1
  7. uuid.Time UnixTime converts uuid.Time into Unix seconds and nanoseconds
