Have you tried showing det_eq_one_of_is_empty directly? Ideally it would be at least as easy as det_eq_one_of_card_eq_zero, so if it is more difficult that would suggest that there are some missing lemmas.

The generalization looks good to me otherwise.

We were missing the unique (perm a) instance needed for my proof. I've added it now, and will wait for a cache.
