## Which issue does this PR close? Closes #6043. ## Rationale for this change Sliding integer sums wrap on overflow, violating ANSI `sum` and `try_sum` semantics. ## What changes are included in this PR? Fall back to Spark for ANSI/TRY integral sums over sliding frames. Legacy sums and ever-expanding frames retain native execution. Update compatibility notes and window test expectations. ## How are these changes tested? SQL regressions cover overflow, NULL/empty frames, recovery, ROWS/RANGE bounds, and native controls. New and affected tests passed on Spark 3.5.9 and 4.1.3. Fork CI passed: [default checks](https://github.com/rich7420/datafusion-comet/actions/runs/35453055248), [Comet Spark 3.4–4.2 tests](https://github.com/rich7420/datafusion-comet/actions/runs/35453066298), and [Spark 4.1 SQL tests](https://github.com/rich7420/datafusion-comet/actions/runs/35453066220). -- This is an automated message from the Apache Git Service.
