On the parity issue, I don’t know the solution, but I have a few thoughts:

I look forward to hearing the actual solution.


P.S. I agree with Melinda about what counts as a solve. Proving you can
solve a puzzle is definitely worthwhile too, even if you don’t carry out
all the motions. This was enough for me on the 120-cell, for instance :)
But it seems like the wiki list should be reserved for actual solves. And
in any case, it sounds like this puzzle is still unsolved from either
