I see that pulling down, but post 1 said the serious buckling is on the lower surface that I can't see. Where is the serious buckling? Near the leading edge? Or near the spar cap? Buckling at the cap would be expected first. So I suspect the pulling down issue is lack of joining the two wings as in flight. Are the two wings connected at the centerline?In the very first post it is the second from last picture. It's looks like the diagonal piece of the rib is pulling down the skin.
The extreme beam loads don't carry into the fuselage. The shear is canceled by the other wing.
