I think my best approach is to move all program execution to precmd.

Yes, because it's actually $(echoti cub $COLUMNS) and I wish it to
work even when the terminal is resized.

...which is even on by default.  The existing stuff is left over from my
old bash prompt; didn't realize zsh did it for me.  (Actually, the full
code did a clear-to-end-of-display, too, which zsh also appears to do by
default.)

I still have an invocation of apm while I'll have to move.
