+# UI Checklist
+
+## Structure
+
+- [ ] No direct `invoke(...)` outside `src/api/tauriCommands.ts`.
+- [ ] New reusable UI uses `src/ui/*` components or extends them.
+- [ ] New business/display logic is not buried in JSX if it can be tested separately.
+- [ ] `App.tsx` was not made worse without justification.
+
+## Accessibility and behavior
+
+- [ ] Buttons have accessible names.
+- [ ] Toggle state uses `aria-pressed` or equivalent.
+- [ ] Tabs/popovers preserve keyboard and screen-reader behavior.
+- [ ] Reduced motion preference is respected where animation is added.
+- [ ] Errors are visible and readable.
+
+## ProxyWarden-specific
+
+- [ ] External SOCKS5 route does not require sing-box.
+- [ ] Local sing-box route requires selected server and readiness.
+- [ ] Route chain matches actual backend state.
+- [ ] Apply readiness gives a clear reason.
+- [ ] Summary remains read-only.
