June 2025 monthly summary for SBNSoftware/sbndcode: Delivered data-driven PandoraShower integration to enhance data reconstruction by leveraging the data calorimetry algorithm within the reconstruction workflow. Implemented and wired in data-motivated PandoraShower modules (commit 7080fcf8866404b0d246b3987b2827ae887f4887) to enable improved shower reconstruction in data processing. Configured modules to use the data calo algorithm, establishing a foundation for more accurate calorimetric analyses in data processing. No major bugs fixed this month; focused on feature delivery and groundwork for robust data-driven reconstruction.

In February 2025, the SBND codebase focused on stability and risk mitigation in the face of an upstream issue affecting vertex refinement. A temporary disablement was implemented to prevent disruptions, preserving reliability for users while the upstream problem is investigated and resolved. This proactive measure minimizes customer impact and provides a controlled path for rollback once upstream fixes are in place.

January 2025 monthly summary: Delivered targeted enhancements in DUNE simulation and testing configuration to broaden control, improve step-limit handling, and enable robust muon testing for the 10kt detector. No major bug fixes were reported in this period; primary focus was feature delivery across two repositories with clear, trackable commits and measurable business value.

December 2024 focused on cross-repo geometry configuration standardization across the DUNE software stack to improve consistency, reproducibility, and analysis reliability. By adopting base_geo and base_auxdet_geo as the standard geometry references, configuration drift was reduced and auxiliary detector references were corrected across duneana, dunereco, and dunecore.

Month 2024-11: Focused on delivering accurate simulation and stabilizing the DUNE10kt workflow in the dunesw repository. Implemented a feature update to Genie flux window sourcing and applied targeted bug fixes to ensure reliable production runs for the 10kt program.

Month: 2024-10. Focused on standardizing and stabilizing the SBND reco2 reconstruction workflow. Delivered a dedicated reco2 workflow configuration, groundwork for drops handling, adoption of a standard reconstruction configuration, and consolidation to standard_reco2_sbnd.fcl. Removed outdated reco2_sce configuration and updated user-facing documentation to reflect SCE services enabled by default. The effort involved 11 commits, including creating a reco2 workflow fcl, adding nominal drops infrastructure, converting to the new format, updating to standard_reco2_sbnd.fcl, removing reco2_sce.fcl, updating the readme, and aligning docs with SCE-enabled standard workflow. This work reduces config drift, improves reproducibility, and sets a solid baseline for future enhancements.

September 2024 monthly summary for DUNE repositories (DUNE/dunesw, DUNE/dunesim). Key focus: advancing 10kt simulation capabilities with improved configuration, parameterization, and flux setup to enhance realism and planning accuracy for the DUNE 10kt program.
