### Description This patch avoids wrapping nullable numeric aggregators when the direct numeric input column is known to have no nulls. This preserves nullable semantics for expressions, unknown nullability, and nullable columns, while allowing specialized query paths to see the underlying numeric aggregator for no-null columns. ### Changes - Skip nullable numeric aggregator wrappers when input column capabilities report numeric type and hasNulls=false. - Add direct-input-column hooks for simple long/float/double aggregators. - Add DoubleSumAggregatorFactory coverage for known no-null and unknown-nullability inputs. ### Tests - mvn test -pl processing -Dtest=DoubleSumAggregatorTest -Dcheckstyle.skip -Dpmd.skip=true -- This is an automated message from the Apache Git Service.
