Worked on enhancing low-energy event handling and detector geometry fidelity in the DUNE dunereco and dunesw repositories, focusing on configuration management and simulation setup. Introduced new parameterization for low-energy cluster detection and updated detector setup definitions using FCL and fcl, improving clustering accuracy for specific geometries. Developed MUSUN generator configurations and adjusted simulation ranges to enable more accurate cosmic ray simulations within rock volumes. Updated detector service configurations to ensure correct service loading for complex geometries. Addressed a reconstruction workflow issue by correcting and later reverting an opflash10ppm configuration, prioritizing pipeline stability and reliability throughout the development process.
