More than low hanging fruit, I think it would have been legitimately hard to find. It only triggered 1/512 runs and probably would have required some expertise in crypto algorithms.

BUT regardless, pruning low hanging fruit for any task IS a force multiplier. So much of so many tasks are easy but tedious. Finding libraries, documentation not matching code thus reading code, correct syntax/arguments, and just tons of straightforward tasks which are not HARD but time consuming.
