Research direction
The issue names scalar correlated subqueries in WHERE and the DependentJoin plan node, but provides no files, tests, entry points, or acceptance criteria. Start by locating DataFusion's correlated-subquery planning and DependentJoin handling, then determine the expected transformation and tests needed to show that the feature is complete.
