Ivan Caro delivered compatibility and data-handling enhancements for overlay workflows in the SBNSoftware/icaruscode and sbncode repositories, focusing on smoother upgrades to LArSoft v10 and more flexible data processing. He updated overlay code and configuration files using C++ and CMake, modernizing build systems and scripts to support new overlay scenarios. In sbncode, Ivan introduced the OverrideRealData parameter to the CAFMaker module, enabling overlay files to be processed as Monte Carlo data with improved handling of POT information. His work demonstrated depth in configuration management and data processing, reducing upgrade risk and improving data fidelity for downstream scientific analyses.

March 2025 monthly summary: Delivered key compatibility and data-handling enhancements for overlay workflows across two SBNSoftware repositories, enabling smoother upgrades to LArSoft v10 and more flexible data processing of overlay datasets. This work reduces upgrade risk, improves data fidelity for downstream analyses, and demonstrates strong cross-repo collaboration on overlay architecture and data handling. Commit-level highlights: - Overlay compatibility with LArSoft v10 in SBNSoftware/icaruscode: added new CMakeLists.txt for decoder and overlays, new .fcl configuration files for multiple overlay scenarios, and updates to OverlayProducts module and related scripts (commit d0ee09282029fdc7703333b5f112282e68461348). - CAFMaker enhancement in SBNSoftware/sbncode: introduced OverrideRealData parameter to treat overlay files as Monte Carlo data, updating POT sourcing from generator information and conditionally setting isRealData (commit f22e5e5bf78a6aa69e96426246dbaa30df77e8c4).
