Contributor guide
Research direction
Start with the attached Vanilla and Gluten-with-CH screenshots and investigate the reported diff when modulo is zero in the ClickHouse backend. No source file, test, Spark version, configuration, or reproducible query is provided, so first establish a minimal reproduction and identify the relevant backend entry point; done means the results match Vanilla for that case.
