• Since PR Move RuleItemChangedBuilder to mode core #34590 was merged, unit tests for creating logical tables through Shardingsphere Proxy have started to fail.

• According to https://github.com/apache/shardingsphere/actions/runs/13588805787/job/37989680341 , this affects both MySQL and Postgres. Move RuleItemChangedBuilder to mode core #34590 seems too long ago.
