During a two-month period, Garren focused on streamlining and maintaining core scientific software repositories, including DUNE/dunecore, DUNE/duneana, and SBNSoftware/sbncode. He removed unused dependencies and legacy modules, such as nusystematics and G4InfoReducer, to reduce build complexity and maintenance risk. Garren integrated the systematicstools library into CAFMaker, enhancing modularity and systematic uncertainty handling. His work relied on C++ and CMake, emphasizing modular programming and software integration. By aligning codebases with refactor strategies and updating documentation, Garren improved maintainability and positioned these projects for future extensibility, demonstrating a methodical approach to software architecture and project stewardship.
