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.NewDCEPerson generates a valid DCE Security (version 2) UUID for Person domain with RFC4122 variant
  2. uuid.NewDCEGroup generates a valid DCE Security (version 2) UUID for Group domain with RFC4122 variant
  3. uuid.Domain constants Person, Group, and Org return expected string representations from String method
  4. UUID.Domain and UUID.ID methods extract domain and principal identifier from DCE Security UUID
  5. uuid.NewDCESecurity generates version 2 UUID preserving custom domain and identifier
  6. uuid.Parse round-trips DCE Security UUID strings preserving Domain and ID
