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. FlagSet.StringVarP binds string flag with long and shorthand names and falls back to default value
  2. FlagSet.IntVarP binds integer flag with long and shorthand names and parses integer values correctly
  3. FlagSet.BoolVarP binds boolean flag with long and shorthand names and parses boolean values correctly
  4. FlagSet.Parse parses argument slice and sets bound variables without error on valid input
