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.

Contract
- uuid.SetNodeID configures 6-byte node ID and returns true for valid slice
- uuid.SetNodeID rejects slices with length less than 6 and returns false
- uuid.NodeID returns copy of currently configured 6-byte node ID
- uuid.SetClockSequence sets lower 14-bit clock sequence
- uuid.ClockSequence returns current clock sequence in range [0, 16383]
- uuid.SetClockSequence with -1 resets and generates new random clock sequence
- uuid.NewUUID generates Version 1 UUID matching configured NodeID and ClockSequence
