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.NewDCESecurity generates a Version 2 UUID for specified Domain and ID
  2. uuid.NewDCESecurity sets Version 2 and RFC4122 variant and returns specified Domain and ID
  3. uuid.NewDCEPerson generates a Version 2 UUID with Person domain
  4. uuid.NewDCEGroup generates a Version 2 UUID with Group domain
  5. uuid.NewDCESecurity produces a 16-byte UUID that round-trips with String() and Parse()
