10. (chainedkodeath.sgf) - Again you'll see KataGo has problems on this one since this is what the patch is trying to fix. I spent some time now hacking KataGo's neural net to manually suggest the correct moves for white with a candidate version with the rules patch, and it evaluates correctly now if you give it enough playouts. So I think that's promising. Also the hack works for a basic double ko death too, so the main question in my mind would be now if there are any bad side effects, since the patch seems to solve the intended cases as intended now.

11. (nopassfight.sgf) - Seems correct. White loses by 0.5, but would win by 0.5 if they could get away with not defending on the top. White has plenty of huge ko threats.

12. I don't have specific tests for these, except for having worked through them by hand with the rules.

13. Hard to have tests to show the nonexistence of a thing, but at least case 11 should demo that the pass fight that should exist under Spight Japanese style rules does not exist for KataGo rules.
