Research direction
Reproduce the issue with the provided Flink SQL against a Hive catalog, starting with SHOW CREATE TABLE and ALTER TABLE ... ADD ... FIRST. Trace the catalog/schema-change handling for column positions; done means adding the column before item_id succeeds without the incompatible-types exception and preserves the intended column order.
