## 🛡️ Critical Security & Privacy Regressions

### 1. E2EE Bypass in Media Gallery Downloads
**File:** `src/app/features/room/MediaGallery.tsx` (Line 855)
**Status:** **CRITICAL**

*   **Issue:** The "Download" button in the Files tab uses `mxcUrlToHttp` directly and clicks an `<a>` link.
*   **Impact:** In encrypted rooms, this downloads the encrypted ciphertext rather than the decrypted file. Users cannot open the downloaded files.
*   **Recommended Fix:** 
    1. Check if the event is encrypted.
    2. If encrypted, use the `decryptAttachment` logic (similar to `useDecryptedMediaUrl`) to decrypt the file in memory.
    3. Use `file-saver` or a Blob URL to trigger the download of the decrypted plaintext.

### 2. Privacy Leak in URL Previews
**File:** `src/app/components/url-preview/UrlPreviewCard.tsx` (Line 1655)
**Status:** **PRIVACY RISK**

*   **Issue:** Generic URL preview cards fetch favicons directly from `https://www.google.com/s2/favicons?domain=...`.
*   **Impact:** This leaks the user's browsing/chat activity (domains of links they see) to Google. It bypasses the "proxied through Matrix" privacy standard.
*   **Recommended Fix:** Use the proxy URL returned by the Matrix `/_matrix/media/v3/preview_url` endpoint instead of contacting Google directly.

## 🚩 Functional & Logic Bugs

### 1. Presence Updater Reverts Status Updates
**File:** `src/app/hooks/usePresenceUpdater.ts` (Line 20)
**Status:** High Priority

*   **Issue:** The `storedStatus` variable is captured once when the `useEffect` starts.
*   **Impact:** If a user updates their status message in the Profile settings, the presence updater hook continues to use the *old* status message from its closure. Every time the user moves their mouse/activity, the hook sends `setOnline` with the stale status, reverting the user's change.
*   **Recommended Fix:** 
    1. Read the status from `localStorage` inside the `setOnline`/`setUnavailable` functions rather than at the top of the effect.

### 2. Audio Playback Rate Reset
**File:** `src/app/components/message/content/AudioContent.tsx` (Line 97)
**Status:** UX Bug

*   **Issue:** The `playbackRate` is set in a `useEffect` that only depends on `[playbackSpeed]`.
*   **Impact:** If a user selects a playback speed *before* the audio blob has finished loading, the `<audio>` element may reset its rate to 1.0 once the `<source>` is added.
*   **Recommended Fix:** Add `srcState.data` to the `useEffect` dependencies or set the `playbackRate` in an `onCanPlay` handler on the audio element.

### 3. Room Insights are Static (No Live Updates)
**File:** `src/app/features/room-settings/RoomInsights.tsx` (Line 60)
**Status:** Medium Priority

*   **Issue:** Stats are calculated in a `useMemo` that only depends on `[room]`.
*   **Impact:** If new messages arrive while the Insights page is open, the statistics (message counts, top participants, etc.) do not update.
*   **Recommended Fix:** Add a listener for `RoomEvent.Timeline` inside the component to trigger a recalculation when new events are added to the room.

### 4. Incorrect Ringing in Voice Rooms
**File:** `src/app/components/CallEmbedProvider.tsx`
**Status:** Logic Bug

*   **Issue:** Joining a static voice room (Public Space channel) triggers the "Incoming Call" ringing animation and sound. This should only occur for "StartedByUser" intents (DMs and Private Group Calls).
*   **Root Cause:** The ringing logic does not distinguish between persistent voice rooms and user-initiated calls.
*   **Recommended Fix:** Check `room.getJoinRule()` or check for the `m.space.parent` event. If the room is a public voice channel, suppress the ringing animation.

## 🎨 UI/UX & Visual Consistency

### 1. Hardcoded Primary Color in Polls
**File:** `src/app/components/message/content/PollContent.tsx` (Line 245)
**Status:** TDS Violation

*   **Issue:** Uses `rgba(var(--mx-primary-rgb, 0,132,255), ...)` for selected options and borders.
*   **Impact:** Polls look like standard Cinny and ignore the Lotus Terminal Design System (TDS) colors.
*   **Recommended Fix:** Use `var(--lt-accent-cyan)` or the primary theme accent color.

### 2. Inaccessible Room Menu on Mobile
**File:** `src/app/features/room-nav/RoomNavItem.tsx` (Line 643)
**Status:** **MOBILE BUG**

*   **Issue:** The room menu icon (`VerticalDots`) is hidden on mobile because `hover` is never active.
*   **Impact:** Mobile users cannot access room settings, mark as read, or leave rooms from the sidebar.
*   **Recommended Fix:** Ensure the menu button is visible on mobile for the active room or provide an alternative trigger.

### 3. Inconsistent Settings Dropdown Styling
**File:** `src/app/features/settings/general/General.tsx`
**Status:** UI Consistency

*   **Issue:** The dropdowns for "Join & Leave Sounds" and "UI Font" use raw HTML `<select>` elements, which look different from the custom-styled `Menu` used elsewhere.
*   **Recommended Fix:** Replace raw selects with the `Menu` + `PopOut` pattern used in the "Message Layout" setting.

### 4. No Camera Focus During Screenshare
**File:** `src/app/features/call/CallControls.tsx`
**Status:** UX Bug

*   **Issue:** When someone is screensharing and another participant turns on their camera, there is no way to switch the primary display to the camera or go fullscreen on it.
*   **Recommended Fix:** Implement a "Pin/Focus" toggle on participant tiles that overrides the automatic screenshare spotlight.
