Johnatan Georges enhanced the TRaSH-Guides/Guides repository by improving the data quality of the sonarr-french configuration. He updated the release-groups-french.json file, adding new French scene groups, correcting an existing group name, and removing trailing whitespace to ensure consistent parsing. Using his skills in configuration management and data management, Johnatan focused on JSON data structures to streamline release group matching and reduce manual curation. These targeted changes improved the accuracy and completeness of release group information, resulting in smoother automation and a better end-user experience for French releases. The work demonstrated careful attention to data integrity and maintainability.
