The data was disposable. Theres an arguement for not using zfs at all with
these two disks as it contained only a poudriere installation. In the end, I
deleted the pool and re-created it, and moved poudriere configs off to another
server. Fortunately the disk seems overengineered in the remappable space
department, with 759 sectors remapped. At least that number isnt increasing.
smartctl -t long passes.
Seems what I should have done is zpool replace ada3 ada3 after fixing the
failing disk, in order to retain the mirror.

Funny you mention this, I'm doing exactly this (with cvs too) for the same
purpose, on a dedicated machine.
thanks for your help,
