# Client-Side Routing

## Rule

All templates are single-page apps using React Router. **Navigation must not remount the app shell.** The agent sidebar, document tree, and any other persistent chrome must survive route changes.

## Why

If the shell unmounts on every navigation, the agent chat reconnects/reloads, destroying in-progress work and hammering the backend.

## Hard Rule

**The app shell (AgentSidebar + any top-level navigation) must be mounted ONCE, above the `<Outlet />`.** Never wrap each page in its own `<AppLayout>` / `<Layout>`. React sees a different component at the outlet position on each nav and unmounts the entire subtree.
