Worked on the VATSIM-UK/UK-Sector-File repository to enhance data integrity by performing targeted data-cleanup operations. Focused on configuration and data management, the developer removed the Coventry (EGBE) entry from the UK sector file and systematically purged all related references in agreement and sector ownership mappings. The process included updating the CHANGELOG.md file to document the changes for future traceability and audit purposes. Utilizing text-based configuration management techniques, the work improved sector data accuracy and reduced the risk of misrouting or data drift. This contribution strengthened governance and ensured the sector file remains reliable for downstream systems and users.
