During a three-month period, John Zennamo enhanced the SBNSoftware/icaruscode and SBNSoftware/sbncode repositories by developing and refining detector simulation and data processing configurations. He delivered a YZ simulation configuration for the ICARUS detector, updating FCL and Jsonnet files to improve analysis workflows and data handling. John implemented storage-efficient cosmic ray data processing by disabling unnecessary GENIE event records and addressed indexing and versioning issues to ensure data integrity. In C++, he fixed a subtle reference bug in BNBEXTRetriever, improving reliability for downstream analyses. His work demonstrated depth in configuration management, C++ development, and detector simulation configuration.
In July 2025, completed a critical bug fix in SBNSoftware/sbncode that ensures ExtInfo modifications within BNBEXTRetriever are applied to the actual vector elements by iterating with a reference. This corrected a subtle in-loop off-by-reference behavior, improving data processing reliability and correctness for downstream analyses.

December 2024 focused feature delivery in SBNSoftware/icaruscode, delivering the ICARUS Detector YZ Simulation Configuration to refine YZ analysis workflow and data handling. No major bugs fixed this month; emphasis was on configurability and pipeline readiness, enabling more accurate physics interpretation and faster iteration for YZ analyses.
