In March 2025, Henry improved the event-rate test suite for the DUNE/MaCh3_DUNE repository, focusing on enhancing performance validation and diagnostic clarity. He introduced a second sample configuration and refined the output format, enabling clearer presentation of event rates by oscillation channel and interaction mode. Using C++ and YAML, Henry expanded test coverage and configuration flexibility, which allows for more reliable detection of performance regressions. His work in configuration management, data analysis, and testing resulted in a more robust validation workflow, supporting reproducible test scenarios and improved visibility into event-rate behavior across different operational modes within the MaCh3 component.
