Operator confirms the instance has never used DeviantArt, so there is nothing for 0088 to quiesce. The migration only ever had two jobs — disable leftover `source` rows and delete a stale `credential` row — and both were guards against data that does not exist here. Removing it rather than keeping a no-op: a migration that runs on every deploy to touch zero rows is a permanent cost paid for a hypothetical, and it would read to a future reader as evidence that DeviantArt sources once existed. `platform` has no CHECK constraint, so retiring the key needs no schema change of its own. alembic head returns to 0087.
