Couple of things... one simple question and another ridiculous perhaps...
First... you have a window unit for cooling.... is there a need for makeup air? I realize those things don't push much air... but then again, it's not a big space either. Wasn't sure if you considered, or if there's even a need for a vent of somesort for makeup air. Didn't see it mentioned.
Second... and I see this was brought up already.... what if someone closes the exterior doors with you inside? You mentioned you lock the mechanism in the open position which is very smart. It's wildly unlikely of course, especially with that precaution... but I guess I'd be a bit nervous about the possibility of some idiot doing such a thing. I guess you could always go out the port for the window unit by knocking it out? Otherwise you're literally trapped in a metal box with no way out.
