Browser tests and security scan
The AI writes real user flows and a real browser runs them on desktop and mobile.
The Proof tab
“Run browser tests” writes 2–4 flows (like sign up then book) and a Chromium browser runs them inside the app's sandbox, with screenshots. They don't block publishing.
Every Proof run also checks for leaked keys, common web-security mistakes, package vulnerabilities and database security rules; critical findings block publishing.
