21A != xx65xx (because bottom half of puzzle is then unresolvable).
Therefore 21A = xx54xx and solves

Aspie: But the bottom half can be resolved as 10A=82, 8A=71, 21A=146532, 10A=2143, so to say that the bottom half is unresolvable with 21A=xx65xx seems like maybe not exactly what you want to say. Or am I missing something?

21A=xx65xx would violate uniqueness because the rest of 21A could be solved 2 ways. And once you see this, it is NADA.

Nada - tip from Aspie re 21A solves it easily

Willo, well yes it could be written as 21A = 146532, but also by 236541, and there would be no way to say which solution was correct. I guess that’s a form of the unique rule, but it’s also viewable as an unallowable disconnect between the top and bottom of the puzzle (if 65 is in, then the top doesn’t influence the bottom, which negates that the orphans have to add up). I think (!)

Easy with orphans

nada

Orphans, and still needed Aspie's hint, not satisfactory, I still prefer to proove uniqueness.

Nada.
