                 <li><strong>Chat becomes inert after UI reload.</strong> After a UI reload (e.g. crash recovery), the frontend's <code>loading</code> state was <code>false</code> even though the backend was still streaming. Added <code>get_chat_status</code> Tauri command that returns <code>true</code> if the backend is streaming. Frontend <code>init()</code> now calls <code>get_chat_status</code> and restores <code>loading = true</code> if the backend is still active. <em>Files: <code>chat.rs</code>, <code>lib.rs</code>, <code>useChat.ts</code></em></li>
                 <li><strong>Can't scroll to bottom after crash/reload.</strong> After reload, the scroll container starts at the top. The <code>isUserAtBottomRef</code> quickly becomes <code>false</code> from the scroll handler, so streaming auto-scroll stops working. Added an initial scroll-to-bottom effect that fires once when messages first load, ensuring the user sees the latest content and <code>isUserAtBottomRef</code> stays <code>true</code> for streaming auto-scroll. <em>Files: <code>ChatPanel.tsx</code></em></li>
