# Lotus Chat — Master Feature TODO

**Location:** `/root/code/cinny/LOTUS_TODO.md`  
**Repo:** `lotus` branch at `https://code.lotusguild.org/LotusGuild/cinny`  
**Deploy:** push to `lotus` → CI → auto-deploy to `chat.lotusguild.org` (~11 min)

This file is the single source of truth for all planned, in-progress, and backlog features.
Update it as features are completed or reprioritized.

## ⚠️ TDS DESIGN LAW — READ BEFORE TOUCHING ANY UI

> **ALL Lotus Terminal Design System (TDS) styling — colors, animations, glows, borders, fonts, spacing — MUST come exclusively from `/root/code/web_template/base.css` CSS variables.**
> Do NOT hardcode hex values. Do NOT invent new variable names. Do NOT deviate from the design tokens defined in that file.
> The canonical variable reference: `--lt-accent-orange`, `--lt-accent-cyan`, `--lt-accent-green`, `--lt-glow-orange`, `--lt-box-glow-*`, `--lt-border-color`, etc.
> Reference implementation for code patterns: `/root/code/tinker_tickets/` (markdown.js, base.js, ticket.css)
> This rule applies to EVERY task in this file without exception.

Legend:
- `[AUDIT REQUIRED]` — at least one assumption needs code/server verification before implementing
- `[SERVER CHECK]` — depends on a Synapse feature or MSC; verify on `matrix.lotusguild.org`
- `[LOW PRIORITY]` — implement after all higher-priority items
- `[EXTREME COMPLEXITY]` — multi-sprint, plan separately before touching
- `[BLOCKED]` — cannot build until a server upgrade, upstream MSC, or dependency resolves
- `[IMPROVE]` — feature exists in upstream Cinny; this task enhances it for Lotus Chat

Status: `[ ]` pending · `[~]` in progress · `[x]` completed

## AUDIT RESULTS — completed June 2026

### Server Status
- **Synapse version:** `1.153.0` (released 2026-05-19) — **FULLY UP TO DATE**, no upgrade needed
- **Matrix spec reported:** up to `v1.12` formally, but newer MSC features available via `unstable_features`
- **MSC feature flags confirmed ON:** `msc4140` (delayed messages) · `msc3771` (thread receipts) · `msc3440.stable` (threading) · `msc4133.stable` (extended profiles) · `simplified_msc3575` (sliding sync)
- **MSC feature flags confirmed OFF:** `msc4306` (thread subscriptions — BLOCKED) · `msc3882` · `msc3912` · `msc4155`
- **MSC3266** (room summary, v1.15): endpoint returned 404 — NOT available on this server
- **MSC3765** (rich room topics, v1.15): NOT available as stable, but client-side rendering is still worth doing
- **MSC3892** (relation redaction): not listed in flags — NOT supported, feature BLOCKED
- **MSC4260** (report user, v1.14): server at v1.12 formally — NOT available as spec endpoint; **however** report user already exists upstream in Cinny (message reporting via `reportEvent`)
- **MSC4151** (report room, v1.12): merged at exactly v1.12 — should be available ✅

### Upstream Cinny Features Confirmed (exist in upstream — only improve, don't re-implement)
| Feature | Location in upstream | Lotus improvement task |
|---|---|---|
| "Jump to Latest" button | `RoomTimeline.tsx:2180-2192` | #104 — add unread count + animation |
| Mark rooms as read (per section) | `Home.tsx:73-102`, `DirectTab.tsx:29-61` | None needed |
| Room upgrade / tombstone banner | `RoomTombstone.tsx`, `RoomUpgrade.tsx` | None needed |
| Visual speaking indicator | `useCallSpeakers.ts:8-60`, `MemberSpeaking.tsx:1-78` | #107 — TDS animated ring |
| Image + video spoilers (blur/reveal) | `ImageContent.tsx`, `VideoContent.tsx` | #105 — smooth CSS transition |
| Report message per event | `Message.tsx:588-709` — `mx.reportEvent()` | #106 — add category selector |
| Drag-and-drop file upload | `useFileDrop.ts` — works but overlay bug | #73 — fix overlay dismiss |
| Typing indicator (animated dots) | `TypingIndicator.tsx`, `TypingIndicator.css.ts` | #108 — TDS orange dots |
| Pinned messages count badge | Confirmed in upstream header icon | None needed |

### Upstream Cinny Features Confirmed MISSING (we should build these)
Quick Switcher, Sidebar filter, Favorite rooms, Invite link generator, Edit history modal,  
Export history, Room preview before joining, Suggested rooms display, Server notices styling,  
DM last-message preview, Media gallery, Knock-to-join full UX

### Code Architecture Facts (relevant to implementation)
| Finding | Impact |
|---|---|
| `folds AvatarImage` does NOT accept children | Avatar overlays/frames must wrap the Avatar component externally, not nest inside it |
| Sidebar `SidebarItem` has `translateX` on hover | CSS `backdrop-filter` won't work on sidebar items directly — apply to parent wrapper instead |
| Element Call bridge has NO join/leave participant events | Join/leave sounds (#89) must use `m.call.member` Matrix room state events instead |
| Element Call bridge has NO audio level events | Speaking indicator uses CSS polling of EC iframe DOM — no direct event bridge |
| No in-app toast system exists anywhere | Toast redesign (#80) must build a full `ToastProvider` + queue system from scratch |
| Voice message player: `AudioContent.tsx:44-223` | Speed control (#8): add `playbackRate` on the hidden `<audio>` element at line 217 |
| Notification sounds: 2 hardcoded `.ogg` files | Custom sounds (#22): replace file path with settingsAtom value |
| Chat backgrounds: `chatBackground.ts`, applied to `<Page>` in `RoomView.tsx` | Animated wallpapers (#77): add new entries returning CSS animation keyframe strings |
| Push rule UI: mode switcher only, no custom rule creation | Full push rule editor (#61) is a significant build from scratch |
| URL preview: `urlPreview: true` default, `encUrlPreview: false` default | Task #49: only need to change `encUrlPreview` default to `true` + add warning text |
| Private read receipts: `ReceiptType.ReadPrivate` already in SDK | Task #34: very simple — `markAsRead()` in `notifications.ts` already has `privateReceipt` param |
| Right-click room menu: 6 items (Mark read, Notifications, Invite, Copy Link, Settings, Leave) | Task #102: add Mute-with-duration submenu and consolidate |
| Glassmorphism: sidebar uses `translateX` transform | Must apply `backdrop-filter` to a parent div, not the sidebar element itself |
| JetBrains Mono: NOT bundled, relies on system fonts | Font selector (#98): must bundle fonts as `public/font/*.woff2` files |
| GIF links (Giphy/Tenor): render as generic OG preview cards, NOT auto-embedded | Task #42: inline GIF embed needs to be built |
| Composer toolbar buttons (in order): Formatting, Emoji/Sticker, GIF, Location, Voice, Send | Task #43: configurable toolbar is straightforward — buttons are a sequential array |
| Message hover toolbar: quick reactions row already exists inside Menu component | Task #92: quick reaction bar is already partially there via `MessageQuickReactions` |

## PRIORITY 0 — Quick wins: low complexity, high daily value

These are the easiest items to ship and immediately improve the daily experience.
Attack these first; most are single-file changes or simple new components.

---

### [ ] P0-1 · Report Room (MSC4151)
**Spec:** MSC4151, merged ~Matrix spec v1.12. Synapse supports it.  
**Confirmed:** NOT present in upstream Cinny mainline.  
**What:** Add a "Report Room" option in the room header context menu (⋮ or room settings). Opens a modal with a reason text field (required) and a Submit button. Calls:
```
POST /_matrix/client/v3/rooms/{roomId}/report
Body: { "reason": "string" }
```
The homeserver forwards the report to server admins.  
**Where:** `src/app/features/room/RoomViewHeader.tsx` (add menu item), new `ReportRoomModal.tsx` component.  
**Complexity:** Low — one API call, one modal.

---

### [ ] P0-2 · Server support contact display (MSC1929)
**Spec:** MSC1929, stable in Matrix spec.  
**What:** On load (or when Settings → Help & About is opened), fetch:
```
GET /.well-known/matrix/support
```
Parse the `contacts` array and `support_page` URL. Display in Settings → Help & About:
- "Homeserver admin: @jared:matrix.lotusguild.org"
- Link to support page if present
Cache the response in component state; no repeated fetches.  
**Where:** `src/app/features/settings/` Help/About panel.  
**Complexity:** Low — one fetch, display result.

---

### [ ] P0-3 · Server notices distinct rendering (m.server_notice)
**Spec:** CS-API §13.17, stable.  
**Audit result:** CONFIRMED MISSING. Only `M_CANNOT_LEAVE_SERVER_NOTICE_ROOM` error code exists in `src/app/cs-errorcode.ts` — no rendering differentiation. Server notices currently arrive as plain DMs.  
**What:** The `m.server_notice` room type is set in `m.room.create` content (`type: 'm.server_notice'`). Detect it via `room.getType() === 'm.server_notice'`. Render with:
- A distinct "Server Notice" header badge (server icon + label) in `RoomViewHeader.tsx`
- Slightly different background color (use `color.Warning` or neutral surface)
- Composer hidden/disabled in server notice rooms (check room type in `RoomInput.tsx`)  
**Where:** `src/app/features/room/RoomViewHeader.tsx` (badge), `src/app/features/room/RoomInput.tsx` (hide composer when `room.getType() === 'm.server_notice'`).  
**Complexity:** Low.

---

### [BLOCKED] P0-4 · Reaction / relation redaction (MSC3892)
**Spec:** MSC3892, in Final Comment Period.  
**Server check result:** `org.matrix.msc3892` is NOT in the server's unstable_features list — **NOT supported**. Current full-event redaction behavior is correct and should not be changed. This task is BLOCKED until the homeserver adds MSC3892 support. No action needed now.  
**Complexity:** N/A — blocked.

---

### [ ] P0-5 · Rich room topic rendering (MSC3765)
**Spec:** MSC3765, merged Matrix spec v1.15.  
**What:** Room topics can now include formatted text via the `m.topic` content block (bold, links, italic). Currently topics render as plain text in the room header. Pipe the `formatted_body` of the `m.room.topic` state event through the existing HTML/Markdown renderer (same renderer used for message bodies).  
**[AUDIT REQUIRED]** — Check if `matrix.lotusguild.org` Synapse version supports sending `m.topic` content blocks. Also check if existing room topics on the server have `formatted_body` set. The rendering improvement is worthwhile even if new formatted topics aren't being set yet.  
**Where:** Wherever the room topic is displayed in `src/app/features/room/RoomViewHeader.tsx` or similar.  
**Complexity:** Low — reuse existing HTML renderer.

---

### [ ] P0-6 · Edit history viewer
**Spec:** CS-API §11.8.2 (stable). Edit history is stored as `m.replace` relation events.  
**What:** When a message shows the "edited" label, clicking it opens a popover or small modal listing every prior version of the message with timestamps:
```
Original:  "Hello world"        — 3:41 PM
Edit 1:    "Hello world!"       — 3:42 PM  
Edit 2:    "Hello everyone!"    — 3:45 PM  (current)
```
Fetch edit history via:
```
GET /_matrix/client/v1/rooms/{roomId}/relations/{eventId}/m.replace
```
**[AUDIT REQUIRED]** — Confirm upstream Cinny does NOT already show edit history on click. If it does, this is upstream and should not be added to our README.  
**Where:** `src/app/features/room/message/Message.tsx` — find where "edited" label renders and add click handler.  
**Complexity:** Low — one API call, display list.

---

### [ ] P0-7 · Room preview before joining (MSC3266)
**Spec:** MSC3266, merged Matrix spec v1.15. Synapse supports it.  
**What:** When a user follows a `matrix.to` link or is invited to a room they haven't joined, show a preview card:
- Room avatar, name, topic, member count, join rule
- "Join Room" / "Request to Join" (if knock) / "Accept Invite" button
- "Back" option without joining
Uses: `GET /_matrix/client/v1/rooms/{roomId}/summary`  
**[AUDIT REQUIRED]** — Check if upstream Cinny already has a room preview screen before joining. Many Matrix clients have this. If Cinny has it, this is upstream and only Lotus-specific styling/improvements are needed.  
**[SERVER CHECK]** — Verify `matrix.lotusguild.org` Synapse version supports the `/summary` endpoint.  
**Where:** Likely in the routing/navigation layer when a room is selected but not joined.  
**Complexity:** Low-medium.

---

### [ ] P0-8 · Personal room name overrides (MSC4431)
**Spec:** MSC4431, in review.  
**What:** Let a user rename a room locally — visible only to them. Stored in Matrix account data:
```
PUT /_matrix/client/v3/user/{userId}/account_data/m.room_names
Body: { "rooms": { "!roomId:server": "My Custom Name" } }
```
Access via right-click on room in sidebar → "Rename for me…". Show a small edit icon next to locally-renamed rooms. The original room name remains unchanged for all other members.  
**[SERVER CHECK]** — MSC4431 is still in review; it uses account data which is universally supported even if the MSC isn't finalized. The account data key name may change when merged.  
**Where:** Room nav item context menu, sidebar room list rendering.  
**Complexity:** Low.

---

### [ ] P0-9 · "Back to Latest" button
**What:** A floating pill button that appears at the bottom of the room timeline when the user has scrolled up (away from the live timeline). Displays "↓ Jump to latest" (and shows unread count if applicable, e.g. "↓ 12 new messages"). Clicking scrolls to the live timeline bottom and hides the pill.  
**[AUDIT REQUIRED]** — Confirm this does NOT already exist in upstream Cinny. Check `RoomTimeline.tsx` for any existing "scroll to bottom" UI — there is already a "Jump to Unread" chip (confirmed in code exploration); verify this is distinct.  
**Where:** `src/app/features/room/RoomTimeline.tsx` — add a `TimelineFloat` element at the bottom, shown conditionally based on scroll position.  
**Complexity:** Low.

---

### [ ] P0-10 · Mark all rooms as read
**What:** A single action that sends read receipts for all rooms with unread counts, clearing every unread badge at once. Accessible via:
- Right-click on the "Home" icon in the sidebar → "Mark all as read"
- Or a button in the Home view header  
Iterates all rooms with `room.getUnreadNotificationCount() > 0` and calls `mx.sendReadReceipt(room.getLastActiveTimestamp())` for each.  
**[AUDIT REQUIRED]** — Confirm upstream Cinny does NOT already have this. Check sidebar context menus and Home view for any existing "mark all read" action.  
**Where:** `src/app/pages/client/sidebar/HomeTab.tsx` context menu or `src/app/pages/client/home/Home.tsx` header.  
**Complexity:** Low.

---

### [ ] P0-11 · Spoiler text audit and fix if broken
**What:** The message composer toolbar has a spoiler mark (||spoiler text||). Verify the end-to-end flow:
1. Composer correctly wraps text in `<span data-mx-spoiler>` in `formatted_body`
2. Timeline renderer displays spoiler as blurred/hidden text with a "Reveal" click
3. Mobile touch works for reveal  
If any step is broken, fix it. If all working correctly, close this task with no changes.  
**[AUDIT REQUIRED]** — Full code audit of spoiler mark in toolbar → event content → timeline renderer.  
**Complexity:** Low (audit) — fix complexity TBD.

---

### [ ] P0-12 · URL Preview default settings + security warning
**Audit result:** `settings.ts` line 103: `urlPreview: true` (already on by default) · line 104: `encUrlPreview: false` (encrypted rooms OFF by default).  
**What:** Change `encUrlPreview` default to `true` in `src/app/state/settings.ts`. Add a one-sentence security note next to the encrypted-room toggle in the settings UI:
> "URL previews in encrypted rooms are fetched by your homeserver, which sees the URL but not the message content."  
**Where:** `src/app/state/settings.ts` line 104 (change default), settings UI file for URL preview toggles (find via grep for `encUrlPreview`).  
**Complexity:** Very Low — one default value change + one sentence of UI text.

---

## PRIORITY 1 — High value, moderate effort

Core features that meaningfully expand what users can do every day.

---

### [ ] P1-1 · Quick Room Switcher (Ctrl+K / Cmd+K)
**What:** Global keyboard shortcut opens a floating search modal above all content. Features:
- Fuzzy-search across ALL rooms and DMs by display name in real time
- Keyboard navigable: `↑`/`↓` to move, `Enter` to open room, `Esc` to close
- Shows unread badge count inline next to each result
- Pressing Ctrl+K again while open closes it
- Recent rooms shown immediately before typing  
**Architecture:**
- New component: `src/app/components/QuickSwitcher.tsx`
- Register global hotkey via `useEffect` + `window.addEventListener('keydown')` in `src/app/pages/client/ClientRoot.tsx`
- Use the existing `OverlayContainerProvider` portal (from `App.tsx`) so the modal floats above everything
- Room data: `allRoomsAtom` + `mDirectAtom` from `src/app/state/roomList.ts`
- Style with `folds` `Menu`, `Box`, `Input` components matching existing patterns
- Use `is-hotkey` library (already in the project) for the keybind  
**[AUDIT REQUIRED]** — Confirm upstream Cinny does NOT already have a quick switcher. Check for any existing Ctrl+K handler in `ClientRoot.tsx` or `App.tsx`.  
**Complexity:** Medium.

---

### [ ] P1-2 · Media Gallery
**What:** A scrollable grid of all shared images, videos, and files in a room. Accessible via a new icon in the room header (picture/grid icon). Features:
- Tab bar: Images | Videos | Files
- Infinite scroll / paginated load via `GET /rooms/{roomId}/messages` filtering for `m.image`, `m.video`, `m.file` msgtypes
- Click image → full-screen lightbox (upstream Cinny lightbox)
- Click file → download
- Shows sender + timestamp tooltip on hover
- TDS-aware grid styling  
**Architecture:**
- New component: `src/app/features/room/media-gallery/MediaGallery.tsx`
- Renders as a right-side drawer (similar to the members drawer pattern)
- Add icon button to `src/app/features/room/RoomViewHeader.tsx`
- Paginate backwards from latest event using `/messages?dir=b`  
**[AUDIT REQUIRED]** — Confirm upstream Cinny has no existing media gallery or file browser. Check room header icons and room settings panels.  
**Complexity:** Medium.

---

### [ ] P1-3 · Sidebar Room Filter / Search
**What:** A text input at the top of each room list tab (Home, DMs, Spaces) that filters visible rooms in real time by display name. Ephemeral — clears when you switch tabs. No server calls — pure client-side filter over the loaded room list.  
**Architecture:**
- Add filter `useState<string>('')` to each tab component
- Filter the room array before rendering: `rooms.filter(id => displayName(id).toLowerCase().includes(filter))`
- Show a small `×` clear button when filter is non-empty
- TDS: mono font, dim border input matching the design system  
**Where:** `src/app/pages/client/home/Home.tsx` (Home tab), DMs equivalent, Space room list.  
**[AUDIT REQUIRED]** — Confirm upstream Cinny does NOT already have a filter input in room lists.  
**Complexity:** Low-Medium.

---

### [ ] P1-4 · Enhanced DM List (last message preview + timestamp)
**What:** Show the last message text and relative timestamp ("2 min ago", "Yesterday") next to each DM in the sidebar, like iMessage or WhatsApp. Currently only the room name and unread badge are shown.  
**Architecture:**
- For each DM room: get `room.getLastActiveTimestamp()` and `room.timeline[room.timeline.length - 1]` for the last event
- Render the event body (truncated to ~60 chars), stripping any HTML
- Format timestamp: "just now" / "X min ago" / "Yesterday" / date
- Falls back gracefully if the room has no messages yet  
**[AUDIT REQUIRED]** — Check if upstream Cinny already shows message previews in DM list. Check `src/app/pages/client/direct-messages/` or `DirectTab.tsx` for existing DM list item rendering.  
**Complexity:** Medium — need to extract last event body safely across encrypted/non-encrypted rooms.

---

### [ ] P1-5 · Voice Message Playback Speed Control
**What:** Add a speed toggle to the voice message audio player in the room timeline: `0.75×` → `1×` → `1.5×` → `2×`. Clicking the current speed label cycles to the next. Uses the HTML `<audio>` element's `playbackRate` property.  
**Architecture:**
- `const [speed, setSpeed] = useState(1)`
- On click: `audioRef.current.playbackRate = nextSpeed`
- Render a small clickable pill: `1×` etc., next to the audio controls
- Persist speed preference in `settingsAtom` so it carries across messages  
**[AUDIT REQUIRED]** — Locate exactly where voice messages render in the timeline. Search for `m.audio` / `MSC3245` / `VoiceMessage` in `src/app/features/room/`. The recorder is in `VoiceMessageRecorder.tsx` but the *player* for received voice messages is elsewhere.  
**Complexity:** Low-Medium.

---

### [ ] P1-6 · Poll Creation
**What:** Users can create polls from the message composer. Features:
- "Create Poll" toolbar button (poll icon) in `RoomInput.tsx`
- Modal: question field (required) + 2–10 answer options (add/remove dynamically) + single vs. multiple choice toggle
- Sends `m.poll.start` event (Matrix 1.7 stable format — same JSON we already render):
```json
{
  "type": "m.poll.start",
  "content": {
    "m.poll": {
      "question": { "m.text": "..." },
      "answers": [{ "m.id": "uuid", "m.text": "Option 1" }, ...],
      "max_selections": 1
    }
  }
}
```
- `mx.sendEvent(roomId, 'm.poll.start', content)`  
**Architecture:**
- New component: `src/app/features/room/PollCreator.tsx`
- Wire toolbar button into `src/app/features/room/RoomInput.tsx` (follow GIF picker pattern)  
**Complexity:** Medium.

---

### [ ] P1-7 · Code Syntax Highlighting in Messages
**What:** Color-code fenced code blocks in rendered messages. Language auto-detected from the code fence hint (` ```python `, ` ```js `, etc.).  
**⚠️ MUST match `/root/code/web_template/base.css` exactly.** The web_template defines the canonical token structure for all Lotus apps:
- `.lt-code-block` — container: `bg-secondary`, `border-dim` border
- `.lt-code-header` — header bar with language label + copy button
  - `.lt-code-lang` — mono font, `accent-orange`, uppercase, 0.1em letter-spacing
  - `.lt-code-copy` — dim border/color; hover → cyan; `.copied` state → green
- `.lt-code-block pre` — mono font, 0.8rem, 1.6 line-height, max-height 400px, scrollable
- Syntax token classes (custom tokenizer, NOT highlight.js/Prism):
  - `.tok-kw` → `var(--accent-cyan)` (keywords)
  - `.tok-str` → `var(--accent-green)` (strings)
  - `.tok-num` → `var(--accent-orange)` (numbers)
  - `.tok-cmt` → `var(--color-tok-cmt)` italic (comments)
  - `.tok-fn` → `var(--accent-purple)` (function names)
See `/root/code/tinker_tickets/assets/js/markdown.js` for the reference tokenizer implementation.  
**[AUDIT REQUIRED]** — Check the TDS CSS variables (`--accent-cyan`, `--accent-green`, etc.) are available in Cinny's `lotus-terminal.css.ts` vanilla-extract theme. Map `var(--accent-*)` to the correct folds/vanilla-extract tokens. Also verify the tokenizer approach from tinker_tickets is language-agnostic enough for chat (it may need extension for more languages).  
**Where:** Code block renderer in `src/app/components/message/` or wherever `<pre><code>` is rendered.  
**Complexity:** Medium.

---

### [ ] P1-8 · Favorite / Starred Rooms
**What:** Star any room from its context menu. Starred rooms appear in a dedicated "Favorites" section at the top of the sidebar room list. Uses Matrix's built-in `m.favourite` room tag (account data), so favorites sync across devices and clients automatically.  
```
PUT /_matrix/client/v3/user/{userId}/rooms/{roomId}/tags/m.favourite
Body: { "order": 0.5 }
```
- Right-click room → "Add to Favorites" / "Remove from Favorites"
- Favorites section appears above the regular room list in the Home tab
- Star icon shown on favorited rooms in the list  
**[AUDIT REQUIRED]** — Confirm upstream Cinny does NOT already render `m.favourite` tagged rooms in a special section. Check `src/app/pages/client/home/` for any tag-based room grouping. Some versions of Cinny may already do this.  
**Complexity:** Medium.

---

### [ ] P1-9 · Invite Link Generator (with QR code)
**What:** In room settings (or via right-click on room), a "Copy Invite Link" button that:
1. Generates a `matrix.to` URL: `https://matrix.to/#/!roomId:server?via=matrix.lotusguild.org`
2. Copies it to clipboard via `navigator.clipboard.writeText()`
3. Shows a QR code of the link (use a lightweight QR library e.g. `qrcode` npm package)
4. "Share" button that opens the native Web Share API if supported  
**[AUDIT REQUIRED]** — Check if upstream Cinny already has a "copy invite link" button in room settings. Also check if the room settings panel already shows the room address/alias.  
**Where:** Room settings panel `src/app/features/room-settings/` or room header context menu.  
**Complexity:** Low-Medium.

---

### [ ] P1-10 · Private Read Receipts toggle
**Spec:** CS-API stable — `m.read.private` vs `m.read`.  
**What:** Add a toggle in Settings → Privacy: "Send private read receipts" — when enabled, read receipts are sent as `m.read.private` (only you and the server see them) instead of `m.read` (everyone in the room sees when you read). Default: public (current behavior, unchanged).  
**Architecture:**
- New `settingsAtom` field: `privateReadReceipts: boolean` (default `false`)
- When sending a read receipt, check the setting and use the appropriate type
- Find `mx.sendReadReceipt(...)` call sites and add the `receiptType` parameter  
**[AUDIT REQUIRED]** — Verify the `matrix-js-sdk` version in use supports the `receiptType` parameter on `sendReadReceipt`. Check the SDK's type definitions for this method.  
**Complexity:** Low.

---

### [ ] P1-11 · Knock-to-join UX (Room version 7)
**Spec:** Room version 7 (stable Matrix spec). Join rule: `knock`.  
**What:** Full knock UX for both sides:
- **Knocking:** When a room's join rule is `knock`, show a "Request to Join" button instead of "Join Room". Sends `POST /join` which triggers a knock state event. Show pending state ("Request sent") while waiting.
- **Approving knocks:** Room admins/mods see a notification of pending knocks. In the members drawer or room settings, show a "Pending Requests" section listing knockers with "Approve" (`/invite`) and "Deny" (`/kick`) buttons.  
**[SERVER CHECK]** — Verify `matrix.lotusguild.org` Synapse supports room version 7 and the knock join rule.  
**[AUDIT REQUIRED]** — Check if upstream Cinny handles the `knock` join rule at all. If it does, only the approvals UI on the admin side may be missing.  
**Complexity:** Medium.

---

## PRIORITY 2 — Good value, medium effort or lower daily frequency

---

### [ ] P2-1 · Jump to Date
**What:** A calendar date picker accessible from the room header (small calendar icon). Selecting a date navigates the timeline to the first message on or after that date.  
API: `GET /_matrix/client/v1/rooms/{roomId}/timestamp_to_event?ts={epochMs}&dir=f`  
Returns `{ event_id, origin_server_ts }`. Then scroll the timeline to that event ID using the existing `scrollToEventId` / virtual paginator logic.  
**[SERVER CHECK]** — Verify `matrix.lotusguild.org` Synapse supports the `/timestamp_to_event` endpoint (added in Synapse 1.73 / Matrix spec v1.6).  
**[AUDIT REQUIRED]** — Understand how `RoomTimeline.tsx` handles navigating to an arbitrary event ID that may not be in the current timeline window. The virtual paginator may need to fetch backwards to that event.  
**Where:** `src/app/features/room/RoomViewHeader.tsx` (button), new `JumpToDate.tsx` component.  
**Complexity:** Medium.

---

### [ ] P2-2 · Custom Notification Sounds
**What:** Let users pick from a set of built-in notification sounds for mentions, messages, and DMs. Features:
- Settings → Notifications: sound selector per category (Mention / Message / DM)
- Each option has a preview "▶ Play" button
- "None" option to disable sound for that category
- 4–6 built-in sounds shipped as audio files in `public/sounds/`
- Stored in `settingsAtom`  
**Architecture:**
- Add `notificationSounds: { mention: string, message: string, dm: string }` to `settingsAtom`
- In `ClientNonUIFeatures.tsx` (where notification sounds are currently played), swap out the hardcoded sound URL for the settings value  
**[AUDIT REQUIRED]** — Find exactly where notification sounds play in the codebase. Search for `new Audio(` or `.play()` in `src/app/`. Confirm how many distinct notification categories currently exist.  
**Complexity:** Medium.

---

### [ ] P2-3 · Sort Non-Space Rooms on Home Page
**What:** A sort control on the Home tab for orphan rooms (rooms not in any space). Options:
- **Unread first** — rooms with unread messages appear at top
- **Recent activity** — sort by `room.getLastActiveTimestamp()`
- **Alphabetical** — sort by display name A→Z
Persisted in `settingsAtom` as `homeRoomSortOrder: 'unread' | 'recent' | 'alpha'`. Default: `'recent'`.  
**Note:** Space rooms are reordered by space admins via the Space Lobby — this only affects non-space orphan rooms on the Home tab.  
**[AUDIT REQUIRED]** — Find where orphan rooms are listed on the Home tab. Confirm which hook/atom provides the room list (`useOrphanRooms()` in `roomList.ts`). Verify the sort is applied purely client-side with no server calls needed.  
**Complexity:** Medium.

---

### [ ] P2-4 · Export Room History
**What:** Export a room's messages to plain text, JSON, or HTML. Accessible from room settings (gear icon → "Export Room History"). Features:
- Format selector: Plain Text / JSON / HTML
- Date range filter (optional: all time or custom range)
- Only exports messages where E2EE decryption keys are available locally
- Shows progress bar for large rooms (batched `/messages` calls)
- Downloads as a file via `URL.createObjectURL(blob)` + `<a download>`  
**Note:** Element already has this feature — mention in the landing page comparison table once implemented.  
**Landing page update:** Add "Export room history" row to `/root/code/matrix/landing/index.html` comparison table.  
**[AUDIT REQUIRED]** — Confirm upstream Cinny does NOT have an export feature. Check room settings panels.  
**Complexity:** Medium.

---

### [ ] P2-5 · Notification Quiet Hours
**What:** Set a daily time window when browser notifications are suppressed (e.g., 11:00 PM – 8:00 AM). Toggle + start/end time pickers in Settings → Notifications.  
**Architecture:**
- New `settingsAtom` field: `quietHours: { enabled: boolean, start: string, end: string }` (times as "HH:MM" 24h strings)
- In `ClientNonUIFeatures.tsx` or `SystemNotification.tsx`, before dispatching a browser `Notification`, check:
```ts
function isQuietHours(settings): boolean {
  if (!settings.quietHours.enabled) return false;
  const now = new Date();
  const [sh, sm] = settings.quietHours.start.split(':').map(Number);
  const [eh, em] = settings.quietHours.end.split(':').map(Number);
  // handle overnight ranges (e.g. 23:00 – 07:00)
  ...
}
```
- Client-side only — does not touch Synapse push rules  
**[AUDIT REQUIRED]** — Find the exact location in the codebase where browser `Notification` objects are created. Confirm no other code paths trigger sounds/notifications that also need to be suppressed.  
**Complexity:** Medium.

---

### [ ] P2-6 · Room Activity / Moderation Log
**What:** A filterable log of room state changes, accessible from room settings. Shows:
- Member joins, leaves, kicks, bans, unbans
- Power level changes ("@alice promoted to Moderator by @bob")
- Room name / topic / avatar changes
- Server ACL changes
Filter controls: event type, date range, user. Sorted newest-first.  
Fetches via `/rooms/{roomId}/messages?filter={"types":["m.room.member","m.room.power_levels",...]}` paginated backwards.  
**[AUDIT REQUIRED]** — Check if upstream Cinny already has a room audit log. Also check if Synapse's admin API provides a richer audit log that could be used instead (admin only).  
**Complexity:** Medium.

---

### [ ] P2-7 · Richer Link Preview Cards
**What:** Expand URL preview cards beyond generic title/description/image:
- **YouTube:** Show video thumbnail with a ▶ play overlay, channel name, duration
- **GitHub:** Show repo name, description, star count, language badge, last updated
- **Twitter/X:** Show avatar, handle, tweet text, likes/retweets (if metadata available)
- **Generic improvement:** Better fallback when OG tags are missing  
**Architecture:**
- URL preview data comes from `GET /_matrix/media/v3/preview_url?url=...` (or the client-side oEmbed if homeserver doesn't provide enough data)
- Detect URL domain/pattern and render a domain-specific card component  
**[AUDIT REQUIRED]** — Check what data `/_matrix/media/v3/preview_url` returns for YouTube/GitHub links on `matrix.lotusguild.org`. The homeserver proxies this call — the richness depends on what metadata the target site exposes and what Synapse extracts. Test with real URLs before building domain-specific card logic.  
**Complexity:** Medium.

---

### [ ] P2-8 · Extended Profile Fields (MSC4133 + MSC4175)
**Spec:** MSC4133 + MSC4175, merged Matrix spec v1.16.  
**What:** Support arbitrary profile fields. Specifically:
- `m.tz` — IANA timezone string (e.g. `"America/New_York"`)
- `m.pronouns` — user's pronouns (e.g. `"they/them"`)
- Custom fields: job title, website  
**Display:** Show set fields in the user profile panel/card.  
**Set:** In Settings → Account → Profile, add input fields for each.  
API: `PUT /_matrix/client/v3/profile/{userId}/{field_name}` / `GET /_matrix/client/v3/profile/{userId}`  
**[SERVER CHECK]** — Verify `matrix.lotusguild.org` Synapse version supports MSC4133. This was merged in spec v1.16 (late 2025). May require a Synapse update if the server is running an older version.  
**[AUDIT REQUIRED]** — Check if the `matrix-js-sdk` version in use exposes methods for getting/setting arbitrary profile fields beyond `displayname` and `avatar_url`. If not, use `mx.http.authedRequest()` directly.  
**Complexity:** Medium.

---

### [ ] P2-9 · Show User Local Time in Profile (MSC4175)
**Depends on:** P2-8 (Extended Profile Fields) — needs `m.tz` to be fetchable.  
**What:** In user profile cards and the member list sidebar, when a user has `m.tz` set, display their current local time:
- "Local time: 3:42 PM (UTC-5)"
- Updates every minute via `setInterval`
- Shows a small clock icon before the time  
**[AUDIT REQUIRED]** — Depends on #P2-8 being implemented first. The `m.tz` field must be readable from the profile API.  
**Complexity:** Low (once P2-8 is done).

---

### [ ] P2-10 · Unverified Device Warning on Send (off by default)
**What:** Show a subtle warning in the composer area when a message will be sent to a room containing unverified devices. Features:
- Off by default — toggled in Settings → Security ("Warn before sending to unverified devices")
- When enabled: a small shield icon + "X unverified devices in this room" warning appears above the send button
- User can click to see which devices, or dismiss and send anyway  
**Architecture:**
- Add `warnOnUnverifiedDevices: boolean` (default `false`) to `settingsAtom`
- When setting is on, before rendering the composer, check room members' device trust via `mx.getCrypto()?.getUserDeviceInfo()` or equivalent
- Do NOT block sending — just warn  
**[AUDIT REQUIRED]** — Verify what the `matrix-js-sdk` (version in use) exposes for checking device verification status per room. The Crypto API varies significantly between SDK versions. This is the riskiest part of this feature.  
**Complexity:** Medium.

---

### [ ] P2-11 · Full Push Rule Editor
**Spec:** CS-API §13.13 (stable).  
**What:** A dedicated page in Settings → Notifications showing the full push rule tree:
- Override rules (highest priority)
- Content rules (keyword matching)
- Room rules (per-room overrides)
- Sender rules (per-user overrides)
- Underride rules (lowest priority)
User can: create custom keyword rules, enable/disable any rule, set highlight/notify/silent action, delete custom rules.  
API: `GET /_matrix/client/v3/pushrules/` / `PUT` / `DELETE` per rule.  
**[AUDIT REQUIRED]** — Audit the existing notification settings UI in `src/app/features/settings/`. Confirm exactly which push rules are already exposed and which are missing. The per-room and global mute controls likely use push rules under the hood.  
**Complexity:** Medium-High.

---

### [ ] P2-12 · Server ACL Viewer/Editor (m.room.server_acl)
**Spec:** CS-API §13.8 (stable), `m.room.server_acl` state event.  
**What:** In room settings (visible to admins/mods with sufficient power level), show the current server ACL:
- List of allowed servers (wildcard patterns supported: `*.example.com`)
- List of denied servers
- Toggle: "Allow IP literal addresses" (default: false)
- Add/remove server entries
- Save sends `mx.sendStateEvent(roomId, 'm.room.server_acl', content)`  
**[AUDIT REQUIRED]** — Confirm the required power level to change `m.room.server_acl` (typically 50 or 100). The UI should only render for users with sufficient power. Check if upstream Cinny exposes any ACL UI.  
**Complexity:** Medium.

---

## PRIORITY 3 — Valuable but higher complexity or lower daily frequency

---

### [ ] P3-1 · Message Bookmarks / Saved Messages
**What:** Save any message for later reference. Features:
- "Bookmark" action in the message context menu
- Saved to Matrix account data: `PUT /_matrix/client/v3/user/{userId}/account_data/io.lotus.bookmarks`
- Structure: `{ bookmarks: [{ roomId, eventId, savedAt, previewText }] }`
- Dedicated sidebar panel (new icon in sidebar nav): list of bookmarks with room name, message preview, timestamp, and "Jump to message" button
- Remove bookmark from the panel or from the message context menu  
**Architecture:**
- New hook: `useBookmarks()` for read/write account data
- New panel: `src/app/features/bookmarks/BookmarksPanel.tsx`
- Add sidebar icon  
**[AUDIT REQUIRED]** — Confirm upstream Cinny has no bookmark/saved messages feature.  
**Complexity:** Medium-High.

---

### [ ] P3-2 · Message Scheduling / Send Later (MSC4140)
**Spec:** MSC4140 (Delayed Events). Status: Synapse-stable, not yet in formal spec.  
**First:** SSH to `compute-storage-01` → `pct exec 151 -- bash` (LXC 151 = Synapse) and check:
```bash
grep -i "delayed\|msc4140" /etc/matrix-synapse/homeserver.yaml
# Also check:
curl -s https://matrix.lotusguild.org/_matrix/client/unstable/org.matrix.msc4140/delayed_events
```
**If supported:** Implement send-later UI:
- Hold send button (or right-click → "Schedule…") to open a date/time picker
- On confirm: `POST /_matrix/client/unstable/org.matrix.msc4140/rooms/{roomId}/send/{eventType}?delay={ms}`
- Scheduled messages appear in a "Scheduled" tray in the composer area
- Can be cancelled before they fire via the MSC4140 cancel endpoint  
**If not supported:** Either enable it in Synapse homeserver.yaml, or implement client-side localStorage queue as a fallback.  
**[SERVER CHECK]** — The Synapse audit above is REQUIRED before any implementation work.  
**Complexity:** Medium (if server supports) / High (if needs server config change + client fallback).

---

### [ ] P3-3 · File Upload Compression (opt-in)
**What:** Before uploading images, present the user with an explicit choice:
- Checkbox: "Compress image before uploading"
- Detail text: "Reduces file size and loads faster for everyone. May slightly reduce quality."
- Show: Original size (e.g. "4.2 MB") → Compressed size estimate (e.g. "~380 KB")
- Show: Original dimensions if downsizing  
User must explicitly check the box — compression is NEVER automatic.  
**Architecture:**
- Use browser Canvas API: `canvas.toBlob(cb, 'image/jpeg', 0.82)` for compression
- Show before/after sizes in the upload preview UI
- Only applies to JPEG and PNG; skip for GIF, SVG, WebP  
**[AUDIT REQUIRED]** — Find where image upload preview currently shows in `RoomInput.tsx`. The compression step needs to insert between "file selected" and "upload confirmed".  
**Complexity:** Medium.

---

### [ ] P3-4 · Accessibility Improvements (WCAG 2.1 AA)
**What:** Comprehensive audit and fix pass targeting the critical user paths:
- Room list navigation (keyboard-only)
- Reading messages in the timeline (screen reader announces new messages)
- Composing and sending a reply
- Opening and closing modals (focus trap, return focus)
- ARIA labels on all icon-only buttons  
**Scope:** Do NOT attempt to make every corner of the app AA-compliant in one pass — focus on the golden path (open app → find room → read → reply → send).  
**[AUDIT REQUIRED]** — Run an automated audit first: `npx axe-core` or browser DevTools accessibility tree. Document every violation before writing a single line of code. Prioritize by severity (critical > serious > moderate).  
**Complexity:** Medium-High (audit is the main work).

---

### [ ] P3-5 · Inline GIF Preview for Giphy/Tenor Links
**[AUDIT REQUIRED — DO THIS FIRST]** — Before any implementation, verify the current behavior:
1. Paste a Giphy URL (e.g. `https://giphy.com/gifs/...`) into the Lotus Chat composer and send it
2. Does it auto-embed as an animated GIF, or render as a plain URL preview card?
3. Repeat for Tenor URLs  
**If already auto-embedding:** Close this task — it's handled by the existing URL preview pipeline.  
**If not:** Detect Giphy/Tenor URL patterns in the URL preview renderer and fetch the GIF via the homeserver's `/_matrix/media/v3/preview_url` proxy. If the proxy returns a direct media URL, render it as an `<img>` tag with `loading="lazy"`.  
**Complexity:** Low-Medium (after audit).

---

### [ ] P3-6 · Configurable Composer Toolbar
**What:** Let users rearrange or hide individual composer toolbar buttons (GIF, Sticker, Emoji, File, Voice, Location). Changes stored in `settingsAtom`. Access via a small "⚙ Customize toolbar" option in toolbar overflow.  
**[AUDIT REQUIRED]** — Audit the current toolbar button rendering in `RoomInput.tsx`. Understand the layout system (is it a fixed array or already mapped from config?). Drag-to-reorder may require a DnD library; consider whether reorder is worth the complexity vs just toggle-visibility.  
**Complexity:** Medium-High (drag reorder adds significant complexity).

---

### [ ] P3-7 · Room Stats / Insights Panel (opt-in)
**What:** An opt-in statistics panel in room settings ("Room Insights" tab). Shows:
- Total cached message count
- Top 5 most active members (by message count in local cache)
- Top 5 most used reactions
- Media files shared (count by type)
- Activity heatmap (messages per hour of day)  
**Important:** This panel must be explicitly opened — not shown by default. Do not make it the first tab or visible on room settings open.  
Derived entirely from locally cached events — no server queries beyond what's already loaded.  
**[AUDIT REQUIRED]** — Confirm the local Matrix SDK cache exposes enough event history to make the stats meaningful (depends on how many events are cached). Very small caches will show misleading data.  
**Complexity:** Medium.

---

### [ ] P3-8 · Thread Panel (full side drawer)
**⚠️ LARGEST FEATURE — requires its own planning session before implementation.**  
**What:** A right-side drawer for threaded conversations. Currently "Reply in Thread" exists but there is no panel to read or write thread replies.  
Features:
- Click "Reply in Thread" → opens thread drawer on the right
- Thread root event shown at the top of the panel
- Full message rendering for all in-thread replies (reuse timeline components)
- Reply input at the bottom (full composer with formatting, emoji, etc.)
- Unread count badge on the thread button in the main timeline
- Keyboard shortcut to close thread panel  
**Architecture:**
- New Jotai atom: `activeThreadEventId: string | null`
- New component: `src/app/features/room/thread/ThreadPanel.tsx`
- Rendered alongside `RoomView` as a conditional right panel (mirror the members drawer pattern)
- Filter events in timeline to `m.thread` relation for the active root event ID
- Shares the same `mx` client and room reference as the main timeline  
**[AUDIT REQUIRED]** — Deeply audit how `m.thread` relation events are currently stored and retrieved in the matrix-js-sdk. Understand the thread aggregation API: `GET /rooms/{roomId}/relations/{eventId}/m.thread`. Check if `RoomTimeline.tsx` currently filters out thread replies from the main timeline (it should — confirm).  
**Complexity:** High.

---

### [ ] P3-9 · Policy List / Ban List Subscription UI
**Spec:** CS-API §13.16 (stable), `m.policy.*` events.  
**Note:** User already has Draupnir bot running in all space rooms — this UI complements rather than replaces it.  
**What:** A panel in room/space settings (admin-only) showing:
- Currently subscribed policy list rooms
- Contents of each list: banned users, banned rooms, banned servers (with reason)
- "Subscribe" / "Unsubscribe" actions
- Does NOT implement enforcement — Draupnir handles that  
**[AUDIT REQUIRED]** — Understand how Draupnir reads policy lists on this homeserver. Confirm whether a client-side subscription UI would conflict with or duplicate Draupnir's configuration. May be more useful as a read-only viewer than a write UI.  
**Complexity:** High.

---

## PRIORITY 4 — Specialized, high complexity, or very low priority

---

### [ ] P4-1 · Thread Notification Mode Per-Thread (MSC3771)
**Spec:** MSC3771 (stable). Depends on Thread Panel (#P3-8).  
**What:** Per-thread notification toggle: "All messages" vs "Mentions only". Accessible from the thread panel header. Tracks unread counts separately per thread.  
**[AUDIT REQUIRED]** — Implement after Thread Panel. Requires understanding how the SDK tracks per-thread unread counts.  
**Complexity:** Medium (after thread panel exists).

---

### [ ] P4-2 · Thread Subscriptions (MSC4306)
**Spec:** MSC4306 (Synapse experimental). Depends on Thread Panel (#P3-8).  
**What:** "Follow thread" button to receive notifications for a thread you haven't posted in. Uses MSC4306 subscription endpoint.  
**[SERVER CHECK]** — Verify `matrix.lotusguild.org` supports MSC4306. It is Synapse-experimental and may not be enabled.  
**Complexity:** Medium (after thread panel exists).

---

### [ ] P4-3 · Knock-to-join Notifications for Admins
**Note:** The basic knock-to-join UX is covered in P1-11. This task adds the admin notification side.  
**What:** Space/room admins see a notification badge when there are pending knock requests. A "Pending Join Requests" section in the members drawer or room settings. Approve (invite) or deny (kick) each knock.  
**Complexity:** Medium.

---

### [ ] P4-4 · Math / LaTeX Rendering in Messages (LOW PRIORITY)
**Spec:** CS-API §11.5 (stable) — `formatted_body` can contain LaTeX.  
**What:** Render `$...$` or `$$...$$` LaTeX expressions in message bodies. Use KaTeX (lightweight, ~100KB, renders server-side-compatible CSS). Must gracefully fall back to raw LaTeX text if KaTeX fails.  
**Note:** This is LOW PRIORITY — only useful for academic/technical communities. Implement last.  
**[AUDIT REQUIRED]** — Confirm KaTeX bundle size impact on the Vite bundle. Check if matrix-js-sdk's HTML sanitizer strips LaTeX before it reaches the renderer. The formatted_body sanitization pipeline is the main risk here.  
**Complexity:** Low-Medium.

---

### [ ] P4-5 · Live Location Sharing (MSC3489 + MSC3672) (LOW PRIORITY, HIGH COMPLEXITY)
**Spec:** MSC3489 + MSC3672. Implemented in Element Web.  
**Note:** Static location sharing is already implemented. This adds live/real-time GPS beacons. Very low priority per user preference.  
**What:** Start sharing live location → creates `m.beacon_info` state event → client posts `m.beacon` events on a timer → other users see your position update live on a map.  
**[SERVER CHECK]** — Verify MSC3489 support on `matrix.lotusguild.org`.  
**Complexity:** High. Requires background geolocation API + live map rendering.

---

### [ ] P4-6 · OIDC / SSO Next-Gen Auth (MSC3861) (EXTREME COMPLEXITY, LOW PRIORITY)
**Spec:** MSC3861, merged Matrix spec v1.15. Uses Matrix Authentication Service (MAS).  
**Context:** ~80% of homeserver users have LLDAP/Authelia/SSO accounts. SSO is currently enabled on `matrix.lotusguild.org` but accounts are not yet linked. This would allow users to log in via their SSO credentials.  
**What:** OAuth 2.0 / OIDC login flow, token refresh, account management page linking Matrix identity to SSO identity.  
**EXTREME COMPLEXITY** — requires: MAS deployment/configuration on the homeserver, significant auth flow changes in the client, token refresh handling, session management overhaul.  
**[SERVER CHECK]** — Before any client work, audit whether MAS is already deployed on `compute-storage-01`. Check: `pct exec 151 -- systemctl status matrix-authentication-service` or similar.  
**Complexity:** Extreme. Multi-sprint project. Plan separately.

---

## PRIORITY 5 — Gamer / Aesthetic / Customization features

---

### [!] BUG · Drag-and-drop file overlay doesn't dismiss on hover-away
**Confirmed bug** — drag a file over the window without dropping: the drop overlay persists.  
**Fix:** Ensure `dragleave` fires correctly at the window/document level. Child element boundaries can cause spurious `dragleave` — use a counter or `relatedTarget` check.  
**[AUDIT REQUIRED]** Find the drag-and-drop overlay component in `RoomInput.tsx` or the room view. Confirm the exact event listener structure.  
**Complexity:** Low (bug fix).

---

### [ ] P5-1 · Custom Accent Color Picker (non-TDS mode only)
**What:** A hex/HSL color picker in Settings → Appearance. Chosen color replaces the primary accent throughout the UI: buttons, badges, active states, highlights, presence dot, links. Applied via a CSS custom property override injected into `<head>`.  
**IMPORTANT:** This feature is completely inactive when TDS is enabled — TDS has its own fixed palette. Add this setting under a "Non-TDS Themes" section that is hidden when TDS is active.  
**[AUDIT REQUIRED]** Identify all CSS custom properties that constitute the "accent color" in non-TDS mode. Map them to the folds/vanilla-extract token names.  
**Complexity:** Medium.

---

### [ ] P5-2 · Additional Color Theme Presets
**What:** 5 new one-click theme presets alongside TDS. Each must be a complete, polished system with proper contrast ratios (WCAG AA). All implemented as vanilla-extract themes matching the existing TDS pattern.  
Themes:
1. **Cyberpunk** — deep navy bg (`#0a0015`), electric purple (`#bf5fff`) + hot pink (`#ff2d9b`) accents, neon glow
2. **Ocean** — deep sea blue bg (`#020b18`), teal (`#00c9b1`) + aqua (`#0096d6`) accents, soft feel
3. **Blood Red** — near-black bg (`#0d0203`), deep crimson (`#7a0010`) + bright red (`#ff2233`) accents
4. **Classic Matrix** — pure black bg (`#000000`), phosphor green (`#00ff41`) text + accents
5. **Midnight** — dark charcoal (`#111827`), cool blue-grey (`#6b7ca8`) accents, clean minimal  
**[AUDIT REQUIRED]** Study `src/lotus-terminal.css.ts` for the full token list before designing themes. All tokens must be covered.  
**Complexity:** Medium (design effort is the main cost).

---

### [ ] P5-3 · Glassmorphism Sidebar Toggle
**What:** Semi-transparent sidebar + panels with `backdrop-filter: blur(12px)`. Toggled in Settings → Appearance. Off by default. Best combined with animated wallpapers.  
**[AUDIT REQUIRED]** Check whether `backdrop-filter` works on sidebar elements given the current z-index stack and CSS transforms. Some browsers require `will-change` or specific stacking context to allow blur through.  
**Complexity:** Low-Medium.

---

### [ ] P5-4 · Animated Chat Backgrounds (CSS-animated wallpapers)
**What:** 5 new animated wallpaper options in the chat background picker:
1. **Matrix Digital Rain** — falling character columns (green characters, CSS animation)
2. **Drifting Stars** — slow-moving particle field (CSS dots)
3. **Aurora Borealis** — slow shifting gradient waves (purple/green/cyan)
4. **Grid Pulse** — expanding ring pulses on a dark grid
5. **Fireflies** — slow drifting glowing dots  
All pure CSS animations (keyframes + transforms) — no canvas, GPU-accelerated. Include a "Pause animations" toggle for accessibility. Colors adapt to active theme accent variables.  
**[AUDIT REQUIRED]** Study how existing wallpapers are applied in `lotus-terminal.css.ts` to extend the system correctly.  
**Complexity:** Medium.

---

### [ ] P5-5 · Night Light / Blue Light Filter
**What:** Warm orange overlay `rgba(255, 140, 0, 0.12)` on the full UI. `position:fixed; inset:0; pointer-events:none; z-index:9999`. Intensity slider (0–30%) in Settings → Appearance. Optional: auto-activate after a set hour. Stored in `settingsAtom`.  
**Complexity:** Low.

---

### [ ] P5-6 · Channel / Room Emoji Prefix Support
**What:** Render a leading emoji in a room name slightly larger in the sidebar for visual impact (e.g. 🎮 general). Optional: right-click room → "Set channel emoji" shortcut for admins.  
**Note:** Matrix room names already support Unicode — this is purely a rendering enhancement.  
**[AUDIT REQUIRED]** Confirm upstream Cinny doesn't strip or truncate leading emoji in sidebar room name display. Also confirm emoji in room names works end-to-end on `matrix.lotusguild.org`.  
**Complexity:** Low.

---

### [ ] P5-7 · In-App Notification Toast Redesign (TDS mode only)
**What:** Slim dark card sliding in from bottom-right: user avatar, display name (orange), truncated message preview, room name (dim), × dismiss. 4-second auto-dismiss. TDS variables only — non-TDS keeps existing behavior.  
**[AUDIT REQUIRED]** Find where in-app notification toasts are currently rendered in `src/app/`. May be in `ClientNonUIFeatures.tsx`.  
**Complexity:** Medium.

---

### [ ] P5-8 · Mention Highlight Animation
**What:** Brief pulse/glow animation (0.4–0.6s ease-out) on incoming @mention messages. CSS keyframe: scale 1.0 → 1.005 → 1.0 + background glow pulse. Only fires on new incoming messages, not on page load. Respects `prefers-reduced-motion`.  
**[AUDIT REQUIRED]** Find where mentioned messages receive their highlight class in the timeline. Verify animation doesn't affect scroll position.  
**Complexity:** Low.

---

### [ ] P5-9 · LFG (Looking for Group) Slash Command
**What:** `/lfg` generates a formatted LFG post visible on ALL Matrix clients using standard `m.room.message` HTML. Fields: Game, Players Needed, Platform, Skill Level, Description, DM link. Other clients see clean formatted HTML; Lotus Chat renders an enhanced styled card.  
**[AUDIT REQUIRED]** Test which HTML tags survive Matrix HTML sanitization on Element/FluffyChat before designing the card structure. Test with minimal HTML.  
**Complexity:** Medium.

---

### [ ] P5-10 · Voice Channel User Limit
**What:** Admins set max participants via custom state event `io.lotus.voice_limit: { max_users: N }`. Show "Channel Full (5/5)" to users over the limit. Local enforcement only.  
**[AUDIT REQUIRED]** Check if Element Call has its own participant limit that should be integrated with rather than duplicated.  
**Complexity:** Medium.

---

### [ ] P5-11 · AFK / Idle Auto-Mute in Voice
**What:** Auto-mute mic after X minutes of silence (detected via Web Audio AnalyserNode). Show "You were auto-muted due to inactivity" toast with click-to-unmute. Admin-configurable via `io.lotus.afk_timeout` state event. Disableable in Settings → Calls.  
**[AUDIT REQUIRED]** Verify auto-mute must go through the same CallControl bridge as manual mute.  
**Complexity:** Medium.

---

### [ ] P5-12 · Seasonal / Event Themes
**What:** Automatic + manually toggleable seasonal overlays with CSS particle effects and accent color variants:
- **Halloween** (Oct 15–Nov 1): purple particles, orange accents, spider web pattern
- **Christmas** (Dec 10–Jan 2): snow fall, red/green accents, snowflake pattern
- **New Year** (Dec 31–Jan 1): firework burst animation, gold accents
- **Pride** (June): rainbow gradient accent cycle  
All toggleable manually in Settings → Appearance regardless of date. Respects `prefers-reduced-motion`.  
**[AUDIT REQUIRED]** Design against existing CSS animation system in `lotus-terminal.css.ts`.  
**Complexity:** Medium.

---

### [ ] P5-13 · Avatar Frame / Border Decorations
**What:** Decorative CSS rings/frames rendered around user avatars. Built-in options: TDS Glow (animated orange pulsing), Cyberpunk (rotating gradient), Minimal (thin ring), Gold (supporter cosmetic). Stored in Matrix account data `io.lotus.avatar_frame`. Only visible in Lotus Chat.  
**[AUDIT REQUIRED]** Verify folds Avatar component allows overlay decoration without breaking child-type constraints (see previous white-circle avatar bug).  
**Complexity:** Medium.

---

### [ ] P5-14 · Animated Avatar Overlay Decorations (Discord-style)
**What:** Animated WebM/GIF overlays that float around avatars (transparent center showing avatar). Curated built-in set OR user-uploaded mxc:// overlay. Stored in account data. Only Lotus Chat users see them.  
**[AUDIT REQUIRED]** See #P5-13 audit. Also decide: curated set only vs user-uploadable.  
**Complexity:** Medium.

---

### [ ] P5-15 · In-Call Soundboard
**What:** Grid of short audio clips playable into the call audio stream via Web Audio API (AudioBufferSourceNode → MediaStreamDestinationNode → mixed with mic). Built-in clips + user-uploadable custom clips (stored as mxc://). Accessible from call controls bar.  
**[AUDIT REQUIRED]** Verify the Element Call integration exposes the mic MediaStream for mixing. This is the highest-risk part of this feature.  
**Complexity:** High.

---

### [ ] P5-16 · Custom Join / Leave Sound Effects
**What:** Local-only sounds when participants join/leave a call you're in. Built-in options + per-user settable. Detect via Element Call participant list change events.

**Complexity:** Medium.

---

### [ ] P5-17 · Quick Emoji Reaction Bar (Hover Shortcut)
**What:** Floating mini-bar of 5 most recent reactions above the hover toolbar. One-click react. 6th button opens full emoji board.

**Complexity:** Low-Medium.

---

### [ ] P5-19 · Collapsible Long Messages ('Read more')
**What:** Messages >~20 lines auto-collapsed with "Read more ↓" button. Click to expand inline. Collapse threshold configurable in settings.  
**[AUDIT REQUIRED]** Determine whether CSS `max-height` + `overflow:hidden` or a line-count approach is more appropriate for the current message renderer. Check edge cases with code blocks and media embeds.  
**Complexity:** Medium.

---

### [ ] P5-20 · Quick Reply from Browser Notification
**What:** Inline reply field in browser notification toasts via Notification Actions API. Reply sends as threaded reply to the triggering message.

## BLOCKED FEATURES (waiting on server/MSC support)

These features are confirmed desirable but cannot be built until the listed dependency is resolved.
Check back after each Synapse upgrade — re-run `/matrix/client/versions` and `unstable_features` to see if they've become available.

### [BLOCKED] · Reaction / Relation Redaction (MSC3892)
**Blocked by:** `org.matrix.msc3892` = false on `matrix.lotusguild.org`  
**What it would do:** Cleanly remove a reaction without redacting the parent message.  
**Current behavior:** Full event redaction — acceptable fallback, no user-facing issue.  
**Action when unblocked:** Find `onReactionToggle` redaction call site; swap in MSC3892 endpoint with fallback.

### [BLOCKED] · Room Preview Before Joining (MSC3266)
**Blocked by:** `GET /v1/rooms/{id}/summary` returns 404 — endpoint not available on this server  
**What it would do:** Show room name, topic, avatar, member count before joining.  
**Action when unblocked:** Build pre-join preview card; trigger on unjoined room navigation.

### [BLOCKED] · Thread Subscriptions (MSC4306)
**Blocked by:** `org.matrix.msc4306` = false on `matrix.lotusguild.org`  
**What it would do:** Follow a thread without posting; get notifications for replies.  
**Action when unblocked:** Add "Follow thread" button in the thread panel header (depends on #11 Thread Panel).

### [BLOCKED] · Report User (MSC4260)
**Blocked by:** Server declares only spec v1.12; MSC4260 merged in v1.14 — endpoint may not exist  
**What it would do:** Report a specific user to homeserver admins (separate from reporting a message).  
**Note:** Report Message already exists in upstream Cinny. This would add Report User to the profile panel.  
**Action when unblocked:** Test `POST /_matrix/client/v3/users/{userId}/report`; if 200, add button to user profile.

## AUDITS PENDING

### [x] Audit-1 · Suggested rooms in Space Lobby — CONFIRMED MISSING (build task #51 created)

### [x] Audit-2 · Room upgrade / tombstone UX — CONFIRMED EXISTS in upstream (RoomTombstone.tsx, RoomUpgrade.tsx)

### [ ] Audit-3 · Profile banner image — Matrix protocol support
Research whether Matrix spec or MSC4133 (v1.16) defines a standard profile banner field. `uk.tcpip.msc4133.stable = true` on our server — check if a `banner_url` or similar field is defined. If no cross-client standard exists, do not implement.

### [x] Audit-4 · Visual speaking indicator — CONFIRMED EXISTS (useCallSpeakers.ts, MemberSpeaking.tsx). TDS improvement task #107 created.

## IMPLEMENTATION NOTES

### ⚠️ TDS DESIGN LAW (repeated here for emphasis)
> Every TDS color, animation, glow, border, shadow, and font value MUST come from `/root/code/web_template/base.css`.  
> Never hardcode hex values. Never invent CSS variable names.  
> Key variables: `--lt-accent-orange` · `--lt-accent-cyan` · `--lt-accent-green` · `--lt-glow-*` · `--lt-box-glow-*` · `--lt-border-color` · `--lt-font-mono`  
> Reference implementation: `/root/code/tinker_tickets/` (markdown.js, base.js, ticket.css)  
> This applies without exception to every task marked `[IMPROVE]`, `[Build]`, or any UI change.

### Design Rules
- All new components must respect both TDS dark (`LotusTerminalTheme`) and TDS light (`LotusTerminalLightTheme`) modes
- Non-TDS theme work (custom accent color, theme presets) uses vanilla-extract theme files — match the pattern in `src/lotus-terminal.css.ts`
- Code syntax highlighting token classes: `.tok-kw .tok-str .tok-num .tok-cmt .tok-fn` (defined in `web_template/base.css`)
- `folds AvatarImage` does NOT accept children — wrap Avatar components externally for overlays/frames/borders

### CI/CD Pipeline
```
edit → commit → git push origin lotus
→ Gitea Actions: tsc --noEmit, eslint, prettier (~3 min)
→ Webhook: lotus_deploy.sh on LXC 106 polls CI, then npm ci && npm run build → rsync
→ Live at chat.lotusguild.org (~11 min total)
```

### Per-Feature Checklist (before marking complete)
- [ ] `npx tsc --noEmit` — zero TypeScript errors
- [ ] `npx eslint src/` — zero new errors (warnings OK if pre-existing)
- [ ] `npx prettier --check src/` — formatting passes
- [ ] `README.md` updated (Lotus-custom features only — not upstream Cinny features)
- [ ] `landing/index.html` updated if the feature appears in the comparison table
- [ ] Visually tested at `chat.lotusguild.org` after CI deploys

### Homeserver Access (for server audits)
- **Synapse (Matrix):** LXC 151 on `compute-storage-01` — `pct exec 151 -- bash`
- **Config:** `/etc/matrix-synapse/homeserver.yaml`
- **Version check:** `curl -s https://matrix.lotusguild.org/_matrix/client/versions`
