fix: work through LOTUS_BUGS.md audit items

- ExportRoomHistory: make addEvents() async, call decryptEventIfNeeded()
  before inspecting type/content so E2EE rooms export decrypted text
- UrlPreviewCard: remove Google S2 favicon (privacy leak); show
  generic Icons.Link instead — no third-party external calls
- Profile: add statusDirtyRef so server presence sync cannot clobber
  in-flight emoji insertions or keystrokes; cleared on save/clear
- useLocalMessageSearch: include m.sticker, m.poll.start, and
  org.matrix.msc3381.poll.start in encrypted room search; index poll
  question and answer bodies
- SeasonalEffect: z-index 9997 → 9999 so overlays render above
  animated chat backgrounds
- LOTUS_BUGS.md: mark all resolved, document remaining blocked items

## 🛡️ Critical Security & Privacy Regressions
## ✅ Resolved Issues
### 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.
- **Ringing Modal Fires in Voice Rooms**: Fixed in `CallEmbedProvider.tsx` — only `notification_type === 'ring'` events now trigger the modal.
- **Avatar Decoration Displacement in Profile**: Fixed in `UserHero.tsx``UserAvatarContainer` (position:absolute) now wraps `AvatarDecoration` as the outermost element, keeping the positioning context relative to `UserHeroAvatarContainer`.
- **Export History Broken for E2EE**: Fixed in `ExportRoomHistory.tsx``addEvents` is now async and calls `mx.decryptEventIfNeeded()` before inspecting event type/content.
- **Privacy Leak in URL Previews (Google Favicon)**: Fixed in `UrlPreviewCard.tsx` — Google S2 favicon call removed; a generic folds `Icons.Link` icon is shown instead.
- **Status Emoji Picker Doesn't Insert Emoji**: Fixed in `Profile.tsx``statusDirtyRef` prevents the server-presence sync `useEffect` from overwriting in-flight user input (cleared on save/clear).
- **Encrypted Search Misses Stickers and Polls**: Fixed in `useLocalMessageSearch.ts``m.sticker`, `m.poll.start`, and `org.matrix.msc3381.poll.start` events now included; poll question and answer bodies are indexed.
- **Seasonal Themes Display Behind Chat Background**: Fixed in `SeasonalEffect.tsx` — z-index bumped from 9997 to 9999.
- **Windows Taskbar Badge Black Square**: Fixed in `src-tauri/src/lib.rs``std::ptr::write_bytes` zeros the DIB bits buffer immediately after `CreateDIBSection`; previously uninitialized bytes caused garbage pixels with alpha=255.

## 🚩 Functional & Logic Bugs
## 🛡️ Pending — Critical Security & Logic
### 1. Presence Updater Reverts Status Updates
**File:** `src/app/hooks/usePresenceUpdater.ts` (Line 20)
**Status:** ✅ RESOLVED (June 2026)
* **Issue:** The `storedStatus` variable was captured once when the `useEffect` started.
* **Impact:** If a user updated their status message in Profile Settings, the hook would continue broadcasting the old message on every activity event, silently reverting the change.
* **Fix Applied:** Replaced the single `localStorage.getItem` read with a `readStatus()` function called inside every `setOnline` and `setUnavailable` invocation, ensuring the current value is always used.
### 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:** ✅ RESOLVED (June 2026)
* **Issue:** Joining a static voice room (Public Space channel) triggered the "Incoming Call" ringing animation and sound.
* **Root Cause:** `getStateEvent(room, StateEvent.SpaceParent)` always returned `undefined` because `m.space.parent` events use the parent space's room ID as the state key, not an empty string. The ringing suppression check silently failed.
* **Fix Applied:** Replaced `getStateEvent` with `getStateEvents` (plural), which returns all events of a given type regardless of state key. A room with any `m.space.parent` event is correctly identified as a space channel and suppresses ringing.

## 🎨 UI/UX & Visual Consistency
## 🚩 Pending — Functional & UI Bugs
### 1. Hardcoded Primary Color in Polls
**File:** `src/app/components/message/content/PollContent.tsx` (Line 245)
**Status:** TDS Violation
### 1. Avatar Decoration Images Not Rendering
**File:** `src/app/features/lotus/avatarDecorations.ts`
**Status:** **OPEN — Blocked on infrastructure**
* **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.
* **Issue:** Decoration images in Settings do not load.
* **Root Cause:** The Nextcloud WebDAV URL (`public.php/dav/files/…`) returns `Content-Disposition: attachment`, which browsers refuse to render in `<img>` tags.
* **Required Fix:** Move decoration assets to a CDN or file host that returns `Content-Type: image/png` with `Content-Disposition: inline`. Options: Gitea LFS, Cloudflare R2, or a dedicated static file host. Alternatively, reconfigure the Nextcloud share to serve inline.
* **Blocked by:** Infrastructure change (not a code fix).
### 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.
## 🎨 Pending — UI/UX & Visual Consistency
### 3. Inconsistent Settings Dropdown Styling
**File:** `src/app/features/settings/general/General.tsx`
**Status:** ✅ RESOLVED (June 2026)
### 1. Inconsistent Settings Dropdown Styling
**Files:** `Profile.tsx`, `SystemNotification.tsx`
**Status:** **OPEN — Low priority**
* **Issue:** The dropdowns for "Join & Leave Sounds", "UI Font", and "Seasonal Theme" used raw HTML `<select>` elements, which render differently from the custom-styled `Menu`+`PopOut` used for "Message Layout" and other settings.
* **Fix Applied:** All three raw `<select>` elements replaced with a reusable `SettingsSelect` component using the Menu+PopOut+FocusTrap pattern consistent with the rest of the settings UI.
* **Issue:** Dropdowns for Status Expiry and Notification Sounds use raw HTML `<select>` elements.
* **Recommended Fix:** Replace with the custom-styled `Menu` + `PopOut` pattern used in `General.tsx`.
### 4. No Camera Focus During Screenshare
**File:** `src/app/features/call/CallControls.tsx`
**Status:** UX Bug — blocked by Element Call internals
* **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.
* **Root Cause:** Element Call's spotlight/layout is controlled internally by EC. Lotus Chat injects the call iframe and cannot easily override EC's participant tile behavior without forking the EC widget.
* **Recommended Fix:** Implement a "Pin/Focus" toggle on participant tiles that overrides the automatic screenshare spotlight — requires EC upstream changes or a custom message bridge.
### 5. Ringing Modal Fires in Persistent Voice Rooms
**File:** `src/app/components/CallEmbedProvider.tsx` (line 337342)
**Status:** ✅ RESOLVED (June 2026)
* **Issue:** Joining a persistent voice room (not a DM or transient group call) showed the incoming call ringing modal and animation.
* **Root Cause:** The `isPrivateGroup` condition included `JoinRule.Restricted` and `JoinRule.Knock` rooms. Lotus Guild voice rooms are `Restricted` join-rule rooms. Their `m.space.parent` state event was being checked but some rooms were set up with only the space-side `m.space.child` relationship, leaving no `m.space.parent` on the room itself — so they passed as `isPrivateGroup` and triggered ringing.
* **Fix Applied:** Narrowed `isPrivateGroup` to only `JoinRule.Invite` to match the exact set of rooms where the call button is shown. Also added `room.isCallRoom()` early-exit so rooms with `m.join_rule.call` type never ring.
### 6. Animated Chat Backgrounds Affect Message Content
### 2. Animations Flickering Content (Fireflies)
**File:** `src/app/features/lotus/chatBackground.ts`
**Status:** ✅ RESOLVED (June 2026)
**Status:** **OPEN — Low priority**
* **Issue:** Animated backgrounds that use `filter: brightness()` or `opacity` animations (Digital Rain glow, Grid Pulse brightness, Fireflies glow/blink) applied those effects to the entire `<Page>` element, causing all message content and the composer to flash/flicker in sync with the animation.
* **Root Cause:** `filter` and `opacity` CSS properties affect an element AND all its descendants. Applying these as part of the `animation` shorthand on the `Page` container made them "inherited" visually by everything inside the room view.
* **Side Effect:** `filter` animation also created a CSS stacking context on Page, which pushed Seasonal Theme overlays (position:fixed; z-index:9997) behind the Page compositor layer.
* **Fix Applied:** Removed `animRainGlowKeyframe`, `animGridBrightnessKeyframe`, `animFirefliesGlowKeyframe`, and `animFirefliesBlinkKeyframe` from `chatBackground.ts`. Only `backgroundPosition` / `backgroundSize` animations remain — these are safe and do not affect descendants or create stacking contexts.
* **Follow-up (June 2026):** The initial fix only removed glow/brightness keyframes from the DARK variant definitions. The LIGHT variant `anim-rain` and `anim-pulse` entries still referenced `animRainGlowKeyframe` and `animGridBrightnessKeyframe` (which were no longer imported, causing a build error). Both references removed from LIGHT variants to complete the fix.
* **Issue:** Complex radial-gradient animations cause flickering on some GPUs.
* **Recommended Fix:** Scope animations strictly to background properties and simplify heavy gradients.
### 7. Seasonal Themes Display Behind Chat Background
**File:** `src/app/components/seasonal/SeasonalEffect.tsx`
**Status:** ✅ RESOLVED (June 2026) — root cause was Bug #6
### 3. No Camera Focus During Screenshare
**File:** `src/app/features/call/CallControls.tsx`
**Status:** **OPEN — Blocked on Element Call internals**
* **Issue:** Seasonal theme overlays (position:fixed; z-index:9997) appeared behind animated chat backgrounds.
* **Root Cause:** The `filter` animation on `<Page>` created a CSS stacking context, causing Page's GPU compositing layer to render above the fixed-position seasonal overlay in some browsers. Removing the filter animations (Bug #6 fix) resolves the stacking context issue.
* **Fix Applied:** See Bug #6. No additional changes to SeasonalEffect required.
### 8. Avatar Decoration Images Not Rendering in Settings
**File:** `src/app/features/settings/account/ProfileDecoration.tsx` / LXC 106 nginx
**Status:** ✅ RESOLVED (June 2026)
* **Issue:** Under Settings → Account → Avatar Decoration, no decoration images were visible.
* **Initial (incorrect) diagnosis:** Suspected `loading="lazy"` in a nested scroll container. Changed to `loading="eager"` — images still did not render.
* **Actual Root Cause:** The server nginx Content Security Policy (`img-src` directive) on LXC 106 did not include `https://drive.lotusguild.org`. The browser silently blocked all 99 APNG requests with CSP violation errors (206 violations visible in DevTools console). The lazy-loading change was a red herring.
* **Fix Applied:** Added `https://drive.lotusguild.org` to the `img-src` directive in `/etc/nginx/sites-available/cinny` on LXC 106 (cinny-web-server) and reloaded nginx. Updated config is tracked in `pve-infra/containers/106-cinny-web-server/etc/nginx/sites-available/cinny`.
### 9. Avatar Decoration Grid Spacing Too Tight
**File:** `src/app/features/settings/account/ProfileDecoration.tsx`
**Status:** ✅ RESOLVED (June 2026)
* **Issue:** Decoration preview cells in the settings picker appeared vertically and horizontally squished together with almost no gap between images.
* **Root Cause:** The flex container used `gap: 20px`, but each `52×52` button renders its decoration image with `position: absolute; top: -8px; left: -8px` (INSET=8), so each image bleeds 8px outside the button on all sides. The visual gap between images was `20 - 8 - 8 = 4px` — nearly nothing. Additionally `paddingBottom: 4` clipped the bottom overflow of the last row, and `paddingRight` was absent so the rightmost column clipped.
* **Fix Applied:** Increased `gap` from `20` to `36` (visual gap = 36 - 8 - 8 = 20px), changed `paddingBottom` from `4` to `INSET` (8px), added `paddingRight: INSET`.
### 10. Windows Taskbar Badge Has Black Square Background and Small Number
**File:** `src-tauri/src/lib.rs` (cinny-desktop) — `set_badge_count` command
**Status:** ✅ RESOLVED (June 2026)
* **Issue:** The notification badge overlaid on the Windows taskbar icon had a solid black square background instead of a transparent circle, and the number was too small to read at a glance.
* **Root Cause (black square):** `CreateDIBSection` initialises the pixel buffer to zero (BGRA `0x00000000`). GDI drawing functions (`Ellipse`, `DrawTextW`) paint RGB values but never touch the alpha channel — all pixels retain `A=0`. When every pixel has `A=0`, Windows cannot use per-pixel alpha compositing and falls back to the monochrome mask (`hbm_mask`, all zeros = fully opaque), so the entire 16×16 bitmap is drawn opaque. The corner pixels outside the ellipse are `RGB(0,0,0)` = black, producing the black square.
* **Root Cause (small number):** Bitmap was 16×16 with an 11px font, giving very little room, especially for two-digit counts.
* **Fix Applied:**
1. After all GDI drawing, iterate the pixel buffer and set `alpha = 0xFF` for every non-zero pixel (`*pixel |= 0xFF00_0000`). Corner pixels (zero) retain `A=0` and composite as transparent.
2. Increased bitmap size from `16` to `20` and font height from `11` to `14`.
* **Issue:** There is no way to focus a camera while screenshare is active.
* **Recommended Fix:** Implement a "Pin/Focus" toggle on participant tiles — requires Element Call iframe API support.
