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. assert NewDCESecurity creates Version 2 UUID with RFC4122 variant for given Domain and ID
  2. assert Domain and ID methods correctly extract embedded domain and local ID from UUIDv2
  3. assert NewDCEPerson creates UUIDv2 with Person domain and current process UID
  4. assert NewDCEGroup creates UUIDv2 with Group domain and current process GID
