During March 2026, this developer enhanced the SBNSoftware repositories by focusing on build stability and data-processing improvements for the 10.20.03 release. In sbnobj, they upgraded the build system and introduced new data structures, streamlining analysis workflows and ensuring smoother release readiness. For sbncode, they developed modules to retrieve beam spill data from ICARUS and NuMI, improving the accuracy and efficiency of beam-event processing. Their work included dependency management and version alignment across both repositories, leveraging C++, CMake, and the art framework. These contributions strengthened maintainability and reduced risk in downstream analytics without introducing any new bugs.
