In the assert checking the array dereference of JobVerbTable[verb] in job_apply_verb() the check of the index, verb, allows an overrun because an index equal to the array size is permitted.
Similarly, in the assert check of JobSTT[s0][s1] with index s1 in job_state_transition(), an off-by-one overrun is not flagged either. This is not a run-time issue as there are no callers actually passing in the max value.
