-- BEGIN CHANGE: widen shop history serial_item for multi-item combos/sets
-- Each serial is ~23 chars; CSV of a full set+weapon (~7) fits in 255, but
-- larger bundles / future appends need headroom. VARCHAR(1024) ~40 serials.
-- No index on serial_item today - ALTER is metadata-only on modern InnoDB (instant when possible).

ALTER TABLE `z_shop_history_item`
  MODIFY COLUMN `serial_item` VARCHAR(1024) NOT NULL DEFAULT '';

-- END CHANGE
