**Is your feature request related to a problem? Please describe.** Auron Iceberg native changelog scan currently supports insert-only changelog tasks with a single supported file format. Unsupported changelog inputs, such as non-insert changelog operations or mixed file formats, should remain on Spark execution. Some of these fallback boundaries are not directly covered by tests. **Describe the solution you'd like** Add regression coverage for unsupported Iceberg changelog native scan fallback scenarios. The test coverage should verify that: - changelog scans containing unsupported changelog operations fall back to Spark execution - changelog scans containing mixed file formats fall back to Spark execution - fallback execution still returns Spark-compatible results **Describe alternatives you've considered** One alternative is to rely on the existing insert-only changelog and delete changelog fallback tests. Adding explicit tests for the remaining fallback boundaries makes the supported native changelog scan scope clearer and helps prevent accidental conversion of unsupported changelog inputs. **Additional context** This should be a test-only change. It should not change Iceberg native scan planning or execution logic. -- This is an automated message from the Apache Git Service.
