The offered-range test sees reads that come late and what each tab draws, and the argument guard passes a value whose converter throws something other than a JSON error (#4956)

The argument guard names an enum parameter's members, and refuses a run of digits too long for any integer type by its length (#4956)

The argument guard states no range for a whole number past the type, names the members of an enum list, and records only the parameters a tool advertises (#4956)
