Worked on the dhis2/ui repository to deliver a targeted UX enhancement for the data-only sharing modal, focusing on improving data governance and reducing misconfiguration risks. Developed and implemented comprehensive test coverage using JavaScript and React to ensure that metadata fields remain hidden when metadata sharing is disabled, thereby clarifying the distinction between data and metadata access within the sharing dialog. This feature established a foundation for future UI validation automation and contributed to more robust front end development practices. The work was delivered as a single, focused feature commit, emphasizing careful testing and clear separation of access controls in the user interface.
