Joe Mosbacher migrated the configuration management system in the XENONnT/straxen repository from a legacy cmt:// scheme to a modern xedocs:// approach, standardizing how detector parameters and models are loaded. Using Python and refactoring techniques, Joe replaced all configuration references and removed outdated CMT URLs, reducing technical debt and simplifying parameter management. This transition to a Xedocs-based framework improved data access consistency and laid the groundwork for faster onboarding and deployment of detector configurations. The work demonstrated depth in configuration management and careful governance of detector data, addressing configuration errors and future-proofing the repository’s approach to managing detector models.
