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 6-byte node ID and sets NodeInterface to user
  2. uuid.SetNodeID returns false when byte slice is less than 6 bytes
  3. uuid.NodeID returns a copy of the active 6-byte node ID
  4. uuid.NodeInterface returns name of interface from which NodeID was derived
  5. uuid.UUID NodeID extracts the encoded 6-byte node ID from a Version 1 UUID
  6. uuid.SetNodeInterface selects hardware interface and returns true for default empty string
  7. uuid.SetNodeInterface returns false when requested interface name does not exist
