Research direction
Locate the Spark-compatible `make_interval` UDF in the DataFusion codebase and inspect how its default `is_nullable` value is assigned. Confirm the function's actual nullability behavior and identify the existing coverage for this UDF. Done means the UDF reports the intended custom nullability and the behavior is covered by a regression test.
