As I understand it, there is a difference in the _extent_ of the stall
between the two wings. If that were not the case and both wings were
fully stalled (which would require AOA to be ~90 degrees I think) the
yaw would decay due to fusilage and tail drag?

thought I'd jump in on this one. I've been a Stearman driver for about 30 years and might have about as much time in "unusual attitudes" as right side up. In a fully developed spin, the door on the outside of the spin will be pretty difficult to open, and in fact it's tough to even move yourself out on that side. the old military training in open cockpits was to bail to the inside of the spin if unrecoverable. so, the quick release pins are in the aerobat to ensure you can get the door off- Centrifigal force and wind presssure will keep it closed otherwise.
