Pascal would be fine going in and just winging it, but if all the programmers agreed to only alter certain subroutines or something more planned out then she would go along with that too.

Rewriting a billion lines of code is probably stretching it, so maybe the programmers could focus on drastically cutting the number of reactions the droids can predict. And maybe lowering how long the droids can plan ahead, too. It's all well and good being able to predict millions of reactions in combat, but not if there's only less than a second to act on these predictions before the situation changes again.
