Joe Mosbacher migrated the configuration management system in the XENONnT/straxen repository from a legacy cmt:// scheme to a new xedocs:// standard, focusing on improving how detector parameters and models are loaded. Using Python and leveraging skills in configuration management and refactoring, Joe systematically replaced all configuration references and standardized data access patterns. This transition reduced configuration errors and technical debt, while laying the foundation for more efficient onboarding and deployment of detector configurations. The work demonstrated a thoughtful approach to codebase modernization, emphasizing maintainability and governance of scientific data pipelines, though it was limited in scope to a single feature.
