During March 2025, Yates focused on improving the stability and reliability of the PTB analysis pipeline in the SBNSoftware/sbndcode repository. He addressed a critical build error in PTBAnalysis_module.cc by correcting a variable naming inconsistency, changing 'upbit' to 'upBit' in the array initialization. This C++ fix restored successful compilation and ensured the PTB analysis module functioned as intended, directly supporting downstream data processing. Yates applied his skills in build systems and debugging, verifying the solution through both local builds and continuous integration. The work demonstrated careful attention to maintainability and helped prevent future build issues in the codebase.
