/**
 * Removing the change journal from a store (journal spec §2.3a rules 4 and 10).

 * with a trigger but without `_sync_capture` is ever committed.
 *
 * It never drops `cleo_trigger_suspend`: that table is schema-owned, and the
 * owned guard and side-effect triggers read it (C2). Nor does anything else;
 * gate 36 forbids dropping it.
