What about ripping a few shallow cuts up the underside of the boards. All
the wood flooring I have ever installed (lot of oak and some juniper) has
them from the factory and I assume it is to prevent cupping.

Old birds building board/batten barns used to put the heartwood out and
single nail close to center - what would theoretically be the top of the
crown. Of course, they floated under the battens, rather than edge
glued,
but the use of nails versus adhesive - unless extremely flexible - will
allow a bit more to happen with the wood short of splitting.

Yes, I can see that nailing the heck out of each board, or using screws
even
would help. I just can't bring myself to trust construction adhesive. The
floor needs to move some I expect.
