## 🛡️ Critical Security & Logic

### 1. Edit History Broken for E2EE

**File:** `src/app/features/room/message/EditHistoryModal.tsx`
**Status:** **OPEN**

- **Issue:** The modal fetches edit history via raw `fetch`. The returned events are not decrypted.
- **Impact:** In encrypted rooms, the edit history shows ciphertext or "(no text)" for all previous versions.
- **Recommended Fix:** After fetching raw events, check if they are encrypted. Use `mx.decryptEventIfNeeded(event)` for each event in the chunk before rendering.

### 2. Service Worker Ephemeral Sessions

**File:** `src/sw.ts`
**Status:** **OPEN**

- **Issue:** Access tokens are stored in an in-memory `sessions` Map within the SW.
- **Impact:** Closing all app tabs wipes the sessions. Background tasks (like future push notification handling or media pre-fetching) will fail.
- **Recommended Fix:** Persist the session info (accessToken/baseUrl) in IndexedDB within the Service Worker so it survives app restarts.

## 📱 PWA & Mobile Issues

### 1. No PWA Precaching (Offline Mode Broken)

**File:** `src/sw.ts`, `vite.config.js`
**Status:** **OPEN**

- **Issue:** The Service Worker is missing the `self.__WB_MANIFEST` injection point and `precacheAndRoute` call.
- **Impact:** The app does not work offline and fails PWA installation requirements in most browsers.
- **Recommended Fix:** Add `precacheAndRoute(self.__WB_MANIFEST)` to `sw.ts` and ensure `vite.config.js` has a valid `injectionPoint`.

### 2. PiP Resize Impossible on Mobile

**File:** `src/app/components/CallEmbedProvider.tsx`
**Status:** **OPEN**

- **Issue:** Resizing the PiP window uses `onMouseDown` handlers which do not trigger on touch devices.
- **Impact:** Mobile users cannot resize the PiP window.
- **Recommended Fix:** Implement `onTouchStart` handlers for the resize corners, mapping touch coordinates to the same resize logic.

### 3. Double Background Animation (GPU Waste)

**File:** `src/app/pages/client/SidebarNav.tsx`, `src/app/features/room/RoomView.tsx`
**Status:** **OPEN**

- **Issue:** When Glassmorphism is enabled, the chat background is mirrored to `document.body` while the `RoomView` also renders it.
- **Impact:** Two identical animations (e.g., Digital Rain) run simultaneously, doubling GPU usage on mobile.
- **Recommended Fix:** When Glassmorphism is active, make the `RoomView` background transparent and rely on the `document.body` background.
