Pierfrancesco Butti focused on enhancing the accuracy and clarity of track selector parameter reporting in the andiwand/acts repository. He addressed a bug where the printed output of minimum and maximum bounds for track selector cuts did not reflect the actual applied values, which could lead to confusion during debugging. Using C++ and leveraging his debugging and software development skills, Pierfrancesco introduced helper lambdas to dynamically print minimum, maximum, or both values as appropriate. This approach improved the maintainability and traceability of track parameter reporting, ensuring that diagnostic outputs now accurately mirror the underlying logic and support more efficient issue resolution.
