-- t-paliad-183 down — reverts the priority flips written by
-- 083_backfill_priority.up.sql.
--
-- "Revert" here means: restore the post-Slice-1 column default
-- ('mandatory' on every row). Mig 078 created the column with that
-- default; post-Slice-1 every row was 'mandatory' regardless of its
-- (is_mandatory, is_optional) pair. Resetting to 'mandatory' is
-- therefore equivalent to "undo the backfill".
