Month 2025-09: In alphagov/publisher, delivered reliability and UX enhancements for editing workflows. Implemented a breadcrumb removal validation to ensure a breadcrumb option is selected, with an integration test verifying error display when saving without a selection and proper submission when a valid option is chosen. Introduced an unsaved changes prompt as a reusable module and wired it into the Edit, Metadata, and Related External Links tabs to guard against data loss when navigating away with unsaved changes. These changes improve data integrity, reduce rework from accidental data loss, and provide a more consistent editing experience for publishers.
