Which means that you have to get the bottom fully into the
grooves. Or, at least, far enough to remove the "belly". Once
there, a couple of screws through the bottom into the sides should take
care
of it.

The length of the arc for a 1/2" sag in the center for a chord
length of 36" is 36.0185" -- thus the movement on either end of the
bottom is only about 0.01". Not significant. There's no chance you can
prevent that kind of movement in wood w/ a mechanical fastener from
the side (besides the damage done to the piece in trying to do
that).

No, not from the side, through the side and bottom from the bottom
of the side; i,e, vertically, not horizontally.

Never work, DD's perfectly correct in that; it's the side of the
fastener that you're expecting to constrain less than 10-thou movement
with--ain't a'gonna' happen, wood simply isn't that rigid, plus, as he
says, it'll cobble up the drawer itself somethin' awful in the
attempt.

Wait! You mean that all those jillions of frame and panel doors are
useless???
