Ernst Jonny Lyngøy focused on enhancing access-control enforcement in the Altinn/altinn-access-management-frontend repository, addressing the challenge of non-delegable services within the single rights delegation feature. He implemented targeted UI updates and comprehensive end-to-end tests using TypeScript and Playwright, ensuring that delegation of non-delegable services is reliably prevented. His work included validating delegation behavior and providing clear user feedback paths, which improved policy compliance and reduced the risk of improper access. By concentrating on both front end development and robust testing, Ernst delivered a solution that increased the reliability and verifiability of access-management workflows within the application.
