I can tell you've not been involved in defending against an active attack. You, as the defender, do not get to play the game of "well, if I squint and read it that way, that attack wouldn't work". The attackers get to play "well, hey, if it turns out I do this and that and push it through the other thing, I get access". They are the ones who get to flow through any crack they can find. They are the ones who get to do logic chopping like you're trying to do. You don't get to argue "Well gosh, that team shouldn't have left that one permission open on that one system, that's not a best practice, if they'd followed best practices 100% of the time the attackers couldn't have gotten in...". Your job is to pick up the pieces.
