Monthly summary for 2025-05 focusing on business value and technical achievements across two UI repos. Delivered user session management feature in hmpps-sentence-plan-ui, including a 60-minute timeout, timeout warning, and an 'unsaved information deleted' page. This feature leverages HMRC Frontend components to ensure a consistent UX, and includes end-to-end tests validating the timeout modal and the deleted-information page. Also performed dependency health and security maintenance in hmpps-assess-risks-and-needs-oastub-ui by updating dependencies and synchronizing package-lock.json to improve maintainability, security posture, and stability. These efforts reduce the risk of data loss due to session timeouts and strengthen the security and maintainability posture of the codebases.
