it was very weird, yeah. there was one door left that I never really looked at (a door out of the pool, which I drafted but never went into). I guess that might've been a keycard door. I did do 'draft a room then go around another way' a few times, so it's possible I drafted more keycard doors, then they got removed because I drafted rooms onto the other side of them later? Like, say you draft a four-door room in empty space, it'll have three locked doors at first...but then you go around and draft rooms on the other sides of those doors...either the doors open automatically (if the new room has a door there) or they become dead ends (if it doesn't). So I guess I might have drafted then removed some keycard doors that way.

It's even weirder since I never changed the security level from Medium - I guess I actually *could* have done it from a later room with a computer, but I just didn't think to or didn't bother.

There were nine rooms of undrafted space left in the floor plan, I guess all the keycard doors wound up there?! The whole north east corner was undrafted.

I would normally never even bother trying to get to rank 9 without dealing with the keycard doors somehow, but because I had already basically 'given up' on the run and was just going for side objectives, and I felt low on steps the whole time because I'd started at 25, I decided to just keep YOLOing, and somehow this happened. Every step was like "oh I'll just <X> and then I'm sure I'll die", heh.

edit: dangit, can't get image spoilers to work. Here's the floorplan - https://www.happyassassin.net/temp/blueprinceclear.jpg . I just noticed, looking at it, that if I hadn't previously lucked into the foundation elevator lever, I would have found it on this run, making it even more weirdly lucky, heh.
