During a three-month period, John Zennamo developed and refined simulation and data processing configurations for the SBNSoftware/icaruscode and sbncode repositories. He delivered a YZ simulation configuration for the ICARUS detector, enhancing data handling and analysis workflows by updating FCL and Jsonnet files to support new parameters and processing pipelines. John also improved storage and compute efficiency for cosmic ray data by disabling unnecessary event record saving and addressed indexing and versioning bugs to ensure data integrity. His work, primarily in C++ and configuration management, demonstrated careful attention to correctness, maintainability, and the nuanced requirements of detector simulation software.

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.
