In 2026-01, delivered end-to-end Welsh translations management for forms in alphagov/forms-admin and integrated Welsh change detection with TaskStatusService. Implemented Welsh translations lifecycle (copy, revert, and clear) across forms, pages, and conditions, with mobility_attributes-driven refactors to keep model definitions in sync. Introduced WelshChangeDetectionService to detect translation updates by comparing FormDocuments using Model.mobility_attributes, and integrated it with TaskStatusService to reflect actual content changes rather than relying on a static welsh_completed flag. Improved creator attribution on copies and standardized attribute handling via Mobility API for efficient, maintainable translations. These changes reduce translation drift, improve editor efficiency, and establish a scalable foundation for multilingual content.
