AI-Unified-Process/book-library ? reverse-engineered prompt

Build me a simple book library web app where people can log in and use it based on their role.

I want a clean Vaadin interface with a main navigation, a login page, and protected pages for members and librarians. The app should use Spring Boot, PostgreSQL, Flyway, and jOOQ, and it should come with the database migrations, the data model, and the UI wired together so it actually runs. Keep security in place so the seeded librarian and member accounts can sign in, and make sure the current user is used correctly for anything tied to a person account.

Please also add basic tests so I can verify the UI without a browser when possible, plus an end to end test for the main flow. If you need current library or framework details, look them up online before implementing.
