-## 🔴 Open — Actionable
-
-### Calls / Audio
-
- **N95 — AFK auto-mute keeps the hardware mic active while muted.** `useAfkAutoMute.ts` holds its own `getUserMedia` stream independent of EC's; muting in the UI doesn't stop those tracks, so the OS recording indicator stays lit. Fix: stop the `MediaStream` tracks on mute, re-request on unmute. (Repro: `LOTUS_TESTING.md` L1.)
- **N127 — ML denoise shim is never injected in `vite dev`.** The `lotusDenoise` plugin injects only on `closeBundle` (build), so ML noise suppression is silently inactive during local dev. Add a dev-mode injection (`configureServer` / `transformIndexHtml`). Dev-only impact.
-
-### Security & Privacy
-
- **N97 — Access token stored in plaintext `localStorage`** (`state/sessions.ts`), vulnerable to XSS; device ID likewise. Architectural — needs a token-protection / session-storage redesign.
- **Session writes are non-atomic and not cross-tab synced** (`state/sessions.ts`) — risks inconsistent state / races across tabs.
- **Persisted PII without encryption:** user status message + expiry (`settings/account/Profile.tsx`), unsent composer drafts (`room/RoomInput.tsx`). Leak risk on shared devices.
-
-### PWA / Offline / Notifications
-
- **N105 — Service worker has no `notificationclick` handler** — notification clicks are broken when the tab is closed. Needs `showNotification()` via the SW + a `notificationclick` listener.
- **N107 — SW has no `push` handler** — Web Push delivery is entirely non-functional. Needs a `push` listener + a Matrix push-gateway integration.
- **N108 — No maskable PWA icon** — Android adaptive icons render incorrectly. Needs a maskable icon asset + `purpose: "maskable"` manifest entry.
- **No app-asset caching strategy** (`src/sw.ts`) — no offline capability.
- **`manifest: false`** in `vite.config.js` — may block correct PWA install if not handled externally.
-
-### Dependencies & Build
-
- **`matrix-js-sdk` pinned to a Release Candidate** (`41.6.0-rc.0`); `@atlaskit` and build tools (`vite`, `typescript`, `eslint`) on unstable/experimental pins — review for stable versions; RC SDK is a tree-shaking/bundle-size risk.
- **Build-time overhead:** `lotusDenoise` does heavy sequential `fs` work in `closeBundle`; `viteStaticCopy` config is complex with redundant renames — could be streamlined.
-
-### Code Hygiene / DevEx
-
- **No automated test suite** (`src/`) — no unit/integration tests configured.
- **Extensive `as any` casts** across `src/` — gradual typing cleanup.
- **`types/matrix/` mirrors SDK types** instead of importing them — drift risk.
- **Hardcoded CDN URL** should move to an env var (the decoration CDN is now single-sourced in `avatarDecorations.ts`, but the literal is still in-repo).
- **`patch-folds.mjs` edits `node_modules` directly** — consider `patch-package`.
- **Infra docs:** `contrib/nginx` lacks security headers (HSTS/CSP) + uses rewrites over `try_files`; `contrib/caddy` has a placeholder path. CI/CD (`prod-deploy.yml`): sequential deploy, aggressive 1-min Netlify timeout, `package-manager-cache: false`.
- **README / CONTRIBUTING:** stale upstream bug-tracker/donations/CLA links; README↔CONTRIBUTING misalignment.
- **Architecture notes (low priority):** deep `features/` + `hooks/` nesting, many small coupled hooks, possible dead CSS/components, `SpacingVariant` / `DropTarget` recipe simplification.
- **Git workflow (forward-looking):** keep commits scoped — past monolithic "fix all bugs" commits and inconsistent prefixes hurt `git bisect`.
-
-### Big Projects
-
- **#5 — Seasonal themes & chat-background redesign.** Current backgrounds are basic CSS; goal is high-fidelity, research-backed, GPU-accelerated designs (layered `oklch`, `backdrop-filter`, `contain:paint`) with WCAG-AA overlay contrast. Treat each as its own design sprint.

 ## Voice / Video Call Improvements

-### Element Call Upgrade
+> 🔱 **[EC-FORK] LIVE (2026-06).** Element Call is now our **self-built fork**
+> (`@lotusguild/element-call-embedded@0.20.1-lotus.1`, source at
+> `LotusGuild/element-call`), served same-origin — no longer the upstream
+> pre-built npm bundle. Several in-call behaviors below are now first-class
+> source changes rather than DOM/widget hacks. Background, plan, and the Phase-2
+> work list are in
+> the Element Call fork reference in [`LOTUS_TODO.md`](./LOTUS_TODO.md).

-Upgraded embedded Element Call widget from **0.16.3** to **0.19.4**.
+### Element Call — Self-Built Fork (`0.20.1-lotus.1`)
+
+The embedded widget was upgraded **0.16.3 → 0.19.4 → 0.20.1**, then **forked**.
+We self-build `LotusGuild/element-call` and publish it to our private Gitea npm
+registry as `@lotusguild/element-call-embedded`; cinny consumes that instead of
+`@element-hq/element-call-embedded`. The iframe prints
+`Element Call embedded-v0.20.1-lotus.1` in its console (vs. `embedded-v0.20.1`
+upstream) — the quickest way to confirm a deploy landed the fork.
+
+All custom behavior lives in the fork's `src/lotus/` modules and is **additive
+and dormant by default**, gated by URL flags / widget actions the host opts into,
+so a stock EC config is byte-for-byte upstream behavior.
+
+**Active (cinny drives them today):**

+> `io.lotus.room_quality`) for hard enforcement across all Matrix clients — the
+> client cap is best-effort.
+
+### In-Call Soundboard (P5-15)
+
+A soundboard button (🔔) in the call controls bar opens a popout of the user's
+clips. Clicking one **injects it into the call as a real published LiveKit
+track** (every participant hears it, via the fork's `io.lotus.inject_audio`) and
+plays it locally for the presser (LiveKit doesn't loop your own track back).
+
+- **User-uploadable, like custom emoji/sticker packs.** Clips are stored in the
+  `io.lotus.soundboard` account data event, so they **sync across all your
+  devices**. Upload short audio (≤ 1 MB, ≤ 40 clips) from the popout; delete
+  inline.
+- Authenticated media can't be fetched from the widget's realm, so the host
+  resolves each mxc clip → an authenticated download → a same-session `blob:`
+  object URL and hands that to the widget.
+- Gated by the **Soundboard** toggle (Settings → General → Calls) with a volume
+  slider. The button is hidden when disabled.
+- Files: `utils/soundboardClips.ts`, `hooks/useSoundboard.ts`,
+  `features/call/CallSoundboard.tsx`, `plugins/call/CallControl.ts#injectAudio`.
+
+### Call Quality Controls (P5-31)
+
+Discord-style encoding controls applied to the local tracks via the fork's
+`io.lotus.set_quality` (`RTCRtpSender.setParameters` across all simulcast
+encodings, re-applied on every re-publish/reconnect).
+
+- **User settings** (Settings → General → Calls): Microphone Bitrate,
+  Screenshare Bitrate, Screenshare Framerate (each defaults to **Auto**).
+- **Room-admin caps**: admins set a ceiling in Room Settings → General → Voice
+  (`io.lotus.room_quality` state event); every Lotus client clamps its per-user
+  quality to `min(user setting, room cap)`.
+- Applied by the `useCallQuality` hook on join and whenever settings/caps
+  change; `utils/callQuality.ts` builds the payload (unit-tested).
+
+**Server-enforced call permissions (hard, ALL clients).** The same
+`io.lotus.room_quality` event carries a **publish-source policy**
+(`allow_screenshare`, `allow_camera`) enforced server-side by
+`voice-limit-guard` (matrix repo, LXC 151): it re-signs the LiveKit JWT's
+`canPublishSources`, so the SFU refuses screenshare/camera tracks for **every**
+Matrix client (Element, FluffyChat, our fork) — not just Lotus. Admins toggle
+these in Room Settings → Voice → **Call Permissions**; cinny also hides the
+blocked buttons in the call bar. Enforcement is **live**: the JWT re-sign covers
+new joins, and a background reconcile loop revokes an **in-progress**
+screenshare/camera (via LiveKit `UpdateParticipant`) within ~3 s of an admin
+flipping the policy — so it kills active shares mid-call, not just future ones.
+
+- **Why numeric caps aren't server-enforced:** LiveKit is a pure SFU (forwards,
+  never transcodes) and has no publisher bitrate/fps field anywhere in the JWT
+  grant, room config, server `limit:`, or admin API; stock Element Call ignores
+  room metadata for publish quality. Numeric caps are therefore inherently
+  **cooperative** — our fork honors them, which is the design above. The
+  publish-source policy is the one genuine hard, cross-client lever, and it's
+  implemented.
+- **Not yet**: screenshare resolution control (needs a `getDisplayMedia` hook in
+  the fork).

The **tier default is Browser-native**; when a user opts into ML the default model is **DeepFilterNet 3**.
 - **Series Suppression (Combination):** Optional toggle to run the browser's native stationary noise filter _before_ the ML model. This allows testing the individual performance of the ML model vs the combined effectiveness at removing fan hum.
 - **Noise Gate:** Configurable hardware-style gate with a dB threshold. Hard-cuts all audio when input is below the threshold, ensuring absolute silence between sentences.

 ### Message Forwarding

 Context menu → **Forward** allows forwarding a message to any room the user is a member of.

+### Copy Message Text
+
+Context menu → **Copy Text** copies a message's plain-text body to the clipboard (reply fallback stripped via `trimReplyFromBody`), complementing the existing **Copy Link** (permalink) action. It renders only when the event has a usable text body, so media without a caption doesn't show an empty action.
+
+### On-Device Message Translation
+
+Translate chat messages written in other languages into a language you choose,
+inline in the timeline — running **entirely on your device** so message text
+never leaves it.
+
+- **Per-message translate** — a foreign-language message shows a **Translate**
+  action in its message menu; once translated, the message displays an inline
+  **"Translated from &lt;language&gt; · Show original"** toggle that swaps between
+  the translation and the original text.
+- **Fully on-device / E2EE-preserving** — translation and language detection run
+  through the browser's built-in **Translator** and **Language Detector** APIs
+  (the Chromium on-device AI translation models). Message text is **never** sent
+  to any cloud translation service — no Google / DeepL / Microsoft, not even a
+  self-hosted server — and there is **no network fallback**, so end-to-end
+  encryption is preserved. That privacy guarantee is the whole point of the
+  feature.
+- **Automatic detection** — the language of each message is detected
+  automatically; messages already in your target language are skipped (no
+  Translate action is shown).
+- **Settings (Settings → General → Messages):**
+  - **Translate Messages Into** — your target language (default **English**;
+    ~26 common languages).
+  - **Auto-translate Incoming Messages** (default **off**) — automatically
+    translates foreign-language messages whose on-device language model is
+    already downloaded.
+- **One-time model download** — the first time you translate from a given
+  language, a small on-device model (a few MB) downloads once. Because the
+  browser requires a user gesture for that first download, the initial
+  translation needs a click.
+- **Availability** — Chromium desktop browsers (**Chrome / Edge 138+**) and the
+  **Lotus desktop app** (WebView2 / Chromium). Not available in Firefox, Safari,
+  or mobile browsers; where the APIs are unavailable the feature hides itself and
+  the settings tile shows a note.
+
 ### Draft Persistence

 - Composer drafts are stored in `localStorage` keyed by `roomId`
 - Draft is cleared on successful send
 - The Jotai atom is the primary source of truth; `localStorage` is only read on room mount
+- **Room-nav draft indicator**: a subtle green dot (the composer's shared `DraftDot`, `color.Success.Main`) appears on a room's nav item when it has an unsent message draft (and isn't the open room), so you can see at a glance where you left half-written messages. The dot reuses the composer draft affordance's vocabulary (`role="img"`, aria-label "Unsent draft"). It reacts to the shared draft atom via a memoized `selectAtom(…, hasMsgDraft)` (re-renders only when the flag flips; the atom is written on room-leave, not per keystroke). `useHydrateMsgDrafts` (mounted in `ClientNonUIFeatures`) pre-fills the draft atoms from `draft-msg-*` localStorage on startup so indicators are correct after a reload. Emptiness check shared via the pure, unit-tested `hasMsgDraft` (`src/app/utils/draft.ts`), also used by the composer's `DraftIndicator`.

 ### Message Search Date Range

+### Encrypted Search Cache (P4-8, opt-in)

+Persistent local index for encrypted-room search, so coverage survives page reloads instead of requiring re-pagination + re-decryption every session.

+- **Opt-in, default OFF** (it stores decrypted text at rest): toggle + "Clear cached index" live in the search panel's Encrypted Rooms section, with the privacy note "Stores decrypted text on this device"

+
+### Math / LaTeX Rendering (P4-4)
+
+KaTeX-rendered math in messages, two paths:
+
+- **Spec path (CS-API §11.5):** `<span/div data-mx-maths="…">` in `formatted_body` renders the attribute's LaTeX (block for div, inline for span); on render failure the element's child fallback content shows instead
+- **Plain-text path:** `$…$` (inline) and `$$…$$` (block) with conservative rules — escape-aware (`\$`), currency-guarded (`$5 and $10` stays text), never inside `code`/`pre`
+- **Outgoing interop:** on send, the composer converts `$…$`/`$$…$$` to spec `<span/div data-mx-maths>` HTML in `formatted_body` (extracted before markdown so LaTeX isn't mangled; off inside code), so math renders on Element and every other client — not just Lotus. The plain `body` keeps literal `$…$` as the fallback
+- KaTeX + its CSS load lazily on first math encountered — zero cost to the main bundle
+- Files: `src/app/utils/mathParse.ts` (+14 tests), `components/math/KaTeX.tsx`, `plugins/react-custom-html-parser.tsx` (render), `components/editor/output.ts` (+ `output.test.ts`, outgoing)

 ### Image / Video Captions

-Images and videos can be sent with a caption. The caption and media are sent as a single event.
+Images and videos can be sent with a caption. The caption and media are sent as a single event (caption = the event `body` when it differs from `filename`).
+
+- **Edit caption**: an image/video you sent shows an **Edit caption** action (quick-actions pencil + message menu). It opens the message editor seeded with the current caption; saving sends an `m.replace` whose `m.new_content` preserves the media (`url`/`info`/encrypted `file`/`filename`) and only changes `body`/`formatted_body`. An empty caption removes it (`body` falls back to `filename`). Gated by `canEditCaption` (`utils/room.ts`) to your own image/video messages that carry an MSC2530 `filename`. Caption edits carry `m.mentions` (an @-mention in a caption notifies) and appear in Edit History (diffed by the word-diff) — even after a caption is removed, the "(edited)" marker remains so history stays reachable. No re-upload — encrypted media keeps its original file/key.

 ### Location Sharing

-`m.location` events render an inline map tile using the coordinates from the event content.
+`m.location` events render an inline map tile using the coordinates from the event content. The renderer reads the top-level `geo_uri` and **falls back to the MSC3488 `org.matrix.msc3488.location`/`m.location` `uri`**, so locations from clients that send only the new shape still render (previously they showed as broken); an MSC3488 `description`, if present, is shown above the coordinates.
+
+Sharing your location (composer → location button) sends an **MSC3488-compliant** `m.location` event: the legacy `geo_uri` plus the `org.matrix.msc3488.location` (uri), `org.matrix.msc3488.asset` (`m.self`), and `org.matrix.msc3488.ts`/`m.ts` blocks, and a human-readable `body`. This makes Lotus-shared locations render as proper pins on Element and other clients instead of falling back to plain text.

+- A collapsible "Scheduled" tray in the room shows all pending scheduled messages with individual send-now, edit, and cancel buttons
+- **Send now**: the tray's send button fires a pending message immediately via MSC4140 `action: 'send'` (the server dispatches the stored delayed event now, as a normal timeline event — no cancel+retype). The row is pruned only once the server confirms; a failed send leaves an inline "Could not send now" error with the message still sendable/editable/cancellable.
+- **Edit / reschedule**: the tray's edit button re-opens `ScheduleMessageModal` (seeded with the existing body + send-time) to change the text and/or time. Since MSC4140 has no in-place edit, this is implemented as schedule-new-then-cancel-old; the old copy is only removed once the server confirms cancellation, so a failed cancel leaves a visible, cancellable copy rather than losing the message. Edits go through the plain-text composer (rich content becomes `m.text`).

+`PollContent.tsx` is a fully interactive, spec-correct poll card:

-### Voice Message Playback Speed
+- **Vote / change / clear** in place — sends stable `m.poll.response` (`m.selections`); latest response per voter wins; clearing removes you from the tally. Multi-choice enforces `max_selections` ("Select up to N").
+- **Disclosed vs undisclosed** — undisclosed polls hide counts/percentages/bars (and the vote total) until the poll ends; disclosed polls show live results.
+- **See who voted** — a "Show who voted" toggle (shown only when results are visible, i.e. disclosed live or undisclosed-after-end) reveals the voter names under each answer. The voter list rides the same tally as the counts (`voters: Map<answerId, senderId[]>` populated in `tallyResponses`'s latest-response-per-sender loop), so it can never disagree with the numbers; a re-vote moves the voter, and a cleared vote drops them. Names via `getMemberName`; undisclosed polls stay secret until close.
+- **End a poll** — the poll's creator or a moderator (redact power) can end it via an inline confirm; sends stable `m.poll.end`. Ended polls lock voting, show "Poll closed · Final results", reveal results, and highlight the winner(s) (ties supported). Only responses cast on/before the end event count.
+- **Cross-client** — reads **both** the stable (`m.poll`/`m.id`/`m.selections`) and unstable (`org.matrix.msc3381.poll.*`) wire formats by hand (matrix-js-sdk 41.7.0's poll parsers only speak unstable), and uses the SDK `Poll` model for end-event validation (creator / redact-PL) + before-end response filtering. Polls authored in Element render/vote/end correctly and vice-versa.
+- **Accessibility** — `radiogroup`/`radio` (single, with arrow-key roving) or `group`/`checkbox` (multi) semantics, `aria-checked`/`aria-disabled`, winner announced to AT.

+### Voice Message Playback (waveform + speed)
+
+`AudioContent.tsx` is the shared audio player (timeline + Media Gallery Audio tab):
+
+- **Waveform scrubbing** — voice messages carry an MSC1767 waveform (`org.matrix.msc1767.audio.waveform`, sent by the recorder). Playback renders it as bars that fill with the accent as the clip plays (TDS green under Lotus Terminal), and the waveform **is** the seek control — click, drag, or keyboard (arrows ±5s, Home/End) to scrub (`role="slider"`, ARIA value text). Threaded through `MAudio` (`MsgTypeRenderers.tsx`) + passed directly by the gallery. Regular audio with no waveform keeps the plain seek bar.
+- **Playback speed** — a cycle button (`[0.75, 1, 1.5, 2]×`); a `useEffect` sets `audioElement.playbackRate` and re-applies it on (re)load (the browser resets it).
+- **Recording pause / resume** — `VoiceMessageRecorder.tsx` supports a `paused` state via `MediaRecorder.pause()/resume()`, so you can pause mid-recording and continue without a gap. The duration timer accumulates only active-recording time (paused time is excluded), the waveform/meters freeze while paused and the record dot stops pulsing, and the finish button (which advances to the preview/review step) is a checkmark distinct from the Pause control.

Open it from **Reply in Thread** in the message menu, a reply's thread indicator, or a summary chip; close with **×** or Escape. Reading the panel sends threaded read receipts so per-thread unread counts clear.
+
+### Threads List Panel
+
+A room-level overview of **all** threads, opened from a **Threads** button (🧵) in the room header (mirrors the gallery/widgets toggles). Each row shows the root sender + message snippet, an unread dot, a meta line ("N replies · last reply 5m ago") and a **participant avatar pile**. A segmented **filter** (All / Unread / Participating — the latter via `thread.hasCurrentUserParticipated`) and **sort** (Recent / Oldest, by last-reply time) sit in the toolbar; both persist in localStorage (`cinny_threads_filter_v1` / `cinny_threads_sort_v1`). Clicking a row opens the existing single-thread `ThreadPanel` (reuses `setActiveThreadId`), and reading it clears the row's unread badge live. The list stays live via `ThreadEvent.New/NewReply/Update/Delete` + `RoomEvent.UnreadNotifications` and is virtualized for busy rooms.
+
+- Files: `features/room/thread/ThreadsListPanel.tsx`, `hooks/useRoomThreads.ts` (populates via `room.fetchRoomThreads()` + `room.getThreads()`; last-activity + reply-count + root-edit signature so rows refresh live), `state/threadsList.ts`, pure filter/sort in `utils/threadList.ts` (`filterThreads`/`sortThreads`, unit-tested). Unread mirrors `useThreadSummary`'s logic (`getThreadUnreadNotificationCount`, muted threads zeroed) and renders the app-wide `UnreadBadge` (red for mentions via the Highlight count). Reuses `StackedAvatar`/`useMemberAvatar` for the participant pile and the Bookmarks-panel segmented-control pattern.
+
+### Summary Chips
+
+Root messages in the main timeline show a **"N replies · time"** chip (server-aggregated `m.thread` bundle, or the live Thread once loaded) with an unread badge — threaded replies no longer render inline in the main timeline, so the chip is how conversations stay discoverable.
+
+### Thread Composer
+
+The panel embeds the full composer (uploads, emoji, stickers, GIFs, voice, location, polls) with drafts, reply state, and upload queues **isolated per thread** (`roomId::threadRootId` keys). Replies-to-replies produce spec-correct `m.thread` + `m.in_reply_to` (`is_falling_back: false`). **Slash commands work in threads** — content-transform commands (`/me`, `/notice`, `/shrug`, `/tableflip`, `/unflip`) route into the thread via the normal send path, and room-level commands (`/invite`, `/kick`, …) act on the room; this also matches the command autocomplete, which was already shown in the thread composer. Scheduling is still disabled inside threads (v1).
+
+**↑ to edit last reply**: pressing Up-arrow in the empty thread composer opens the editor on your most recent editable reply _in that thread_ — parity with the main timeline. The thread composer carries a distinct `editableName="ThreadInput"` so the main timeline's global up-arrow handler and the thread's no longer cross-fire (previously the thread composer had the same name, so Up-arrow there wrongly targeted the main timeline's last message).
+
+### Notifications (Slack-style, P4-1)
+
+By default you're notified for a thread reply only when you **participate** in that thread (you've posted in it) or the reply **@mentions** you — other threads accumulate quietly behind their chip badges. Every thread can be overridden from the bell menu in the panel header: **Default (participating) / All replies / Mentions only / Mute**. Modes sync across your devices (`io.lotus.thread_notifications` account data, auto-pruned). Muting a thread silences notifications and sounds, removes the chip's unread badge (a small bell-mute glyph shows instead), and subtracts that thread from the room's sidebar unread badge (client-side — other Matrix clients on the account still count it).
+
+### Under the Hood

+- `threadSupport: true` (startClient) partitions thread events into SDK `Thread` timelines; markAsRead sends **unthreaded** receipts so room badges keep clearing
+- Thread replies are notified via exactly one path (room-level `ThreadEvent.NewReply` w/ per-thread dedupe + panel-aware focus suppression); the main timeline notifier is thread-guarded, and room badges refresh live on `RoomEvent.UnreadNotifications`

+- **Optional comment**: an "Add a comment" field sends a short `m.text` note to each target room _before_ the forwarded message (sequenced per room; a room counts as failed if either send fails).
+- **Recent targets**: a "Recent" chip row (hidden while searching) surfaces the rooms you last forwarded to for one-tap selection. Successful targets are recorded most-recent-first, deduped, capped at 8, in localStorage (`cinny_recent_forward_targets_v1`) via the pure, unit-tested `addRecentForwardTarget` (`state/recentForwardTargets.ts`); rooms you've since left are dropped from the row.

+
+## Desktop App Features
+
+Native capabilities of the Lotus Chat **Tauri v2** desktop app (Windows, macOS, Linux) on top of the shared web client. Web hooks live in `src/app/hooks/useTauri*.ts` (each no-ops in the browser) and call Rust commands in `cinny-desktop/src-tauri/src/native/*`. Windows-only pieces are `#[cfg(target_os = "windows")]`, compile-verified in CI (Windows runners).
+
+### Call Continuity — No-Sleep (P5-46)
+
+Holds the system awake (`SetThreadExecutionState`) while a voice/video call is active; releases on end. `useTauriCallPower` ↔ `native/power.rs`.
+
+### Windows Jump List (P5-36)
+
+Right-click the taskbar icon → a **Recent Rooms** list of your most-active rooms; each entry opens that room via the `matrix:` deep-link. `useTauriJumpList` ↔ `native/jumplist.rs` (`ICustomDestinationList`).
+
+### Taskbar Thumbnail Toolbar (P5-44)
+
+Hover the taskbar preview during a call → **Mute / Deafen / End Call** buttons. `useTauriThumbbar` ↔ `native/thumbbar.rs` (`ITaskbarList3` + a window subclass for `THBN_CLICKED`).
+
+### System Media Transport Controls — SMTC (P5-43)
+
+Exposes call status + a mute control to the Windows volume-flyout / media overlay (WinRT `SystemMediaTransportControls`). `useTauriSmtc` ↔ `native/smtc.rs`. _Experimental — may require an active audio session to surface._
+
+### Network Awareness (P5-49)
+
+Detects Windows connectivity changes (`INetworkListManager`) and nudges the Matrix client to reconnect (`retryImmediately`). `useTauriNetwork` ↔ `native/network.rs`.
+
+### Instant Background Sync (P5-42)
+
+Keeps the `/sync` loop + notifications running full-speed while the app is closed to the tray, by disabling Chromium background throttling via WebView2 `additional_browser_args` (`lib.rs`) — no separate background process. Windows/WebView2 only; doesn't block system sleep.
+
+### Native Rich Notifications (P5-41 / P5-35)
+
+Windows toasts with **click-to-open-room** and **inline quick reply** (WinRT `ToastNotification`, in-process `Activated` event). Falls back to the standard toast otherwise. `useTauriToastActions` ↔ `native/toast.rs`; the desktop notification bridge routes room notifications to it.
+
+### Focus Assist Sync (P5-56)
+
+When Windows Focus Assist / Quiet Hours is active, Lotus suppresses its own notifications + sounds (reuses the quiet-hours gate). `useTauriFocusAssist` + `focusAssistActiveAtom` ↔ `native/focus_assist.rs` (`SHQueryUserNotificationState`).
+
+### Linux parity + cross-platform extras (P6-1)
+
+Rounds out the native app beyond Windows (macOS out of scope):
+
+- **No-sleep during calls on Linux** — a D-Bus `org.freedesktop.ScreenSaver` inhibit (zbus) keeps the display awake mid-call, matching the Windows behavior. `native/power.rs`.
+- **Launcher unread badge on Linux** — best-effort Unity `LauncherEntry` D-Bus signal (Ubuntu/Dash-to-Dock/KDE), mirroring the Windows taskbar badge.
+- **Launch on login** — `tauri-plugin-autostart` + a **Settings → General "Launch on login"** toggle (desktop-only).
+- **Tray "Do Not Disturb"** — a tray checkbox that silences Lotus notifications (feeds `manualDndAtom` into the same quiet-gate as Focus Assist). `useTauriDnd`.
+
+### Custom Window Chrome (P5-47)
+
+Opt-in (Settings → General → **Custom Window Chrome**): replaces the OS title bar with a TDS-styled titlebar (min / max / close + drag region), runtime-reversible via `set_decorations`. `features/desktop/TitleBar.tsx` + `useTauriWindowChrome` ↔ `native/chrome.rs`.
+
+### Proactive Update Toast (P5-40)
+
+Checks for a new desktop release every 12h and offers a one-click update. `TauriUpdateFeature` (ClientNonUIFeatures) + `useTauriUpdater`.
+
+### Cross-platform composer niceties
+
+- **Composer toolbar drag-reorder (P5-55)** — drag to reorder the composer buttons (Settings → General), via `@atlaskit/pragmatic-drag-and-drop`.
+- **Draft-saved indicator (P5-57)** — a subtle cue in the composer when the current room has a persisted draft.
+- **Recursive folder drag-drop (P5-48)** — drop a folder to upload every file inside it (all nesting levels), `utils/fileEntries.ts`.
+
+### Files
+
+- Web: `src/app/hooks/useTauri*.ts`, `src/app/components/TauriDesktopFeatures.tsx`, `src/app/features/desktop/TitleBar.tsx`, `src/app/features/room/DraftIndicator.tsx`, `src/app/utils/fileEntries.ts`, `src/app/state/{customWindowChrome,focusAssist}.ts`.
+- Native (`cinny-desktop`): `src-tauri/src/native/{power,jumplist,thumbbar,smtc,network,chrome,toast,focus_assist}.rs` + `native/mod.rs` (registered in `lib.rs`).

 **Scope:** Everything landed on the `lotus` branch since the v4.12.3 merge that I (Claude) could **not** verify statically and that needs a human in a real environment to confirm. Work through it top-to-bottom; the highest-risk / hardest-to-reproduce items are first.

 > **How to report back:** For each numbered check, tell me **PASS** / **FAIL** (or **partial**). On any FAIL, include: what you saw vs. expected, the browser/OS (and whether web LXC 106 or the desktop/Tauri build), the theme you were on, and any **browser console** errors (F12 → Console).

+## Automated coverage map — what the unit tests already pin (2026-07)
+
+**Read this before working the guide.** Much of the _logic_ these manual checks were written to catch is now locked by deterministic unit tests (`npm test`, 920+ cases, green in CI). Unit tests do **not** prove visual rendering, real-call behavior, the desktop build, E2EE, or cross-device sync — those still need a human. But where a decision is pure logic, you can **trust the test and spend your manual time on the human-only part**. For each row below, the middle column is "don't bother re-deriving this by hand"; the right column is "this is what your manual pass is actually for."

+
+> The whole EC iframe is now our **self-built fork** (`@lotusguild/element-call-embedded@0.20.1-lotus.1`).
+> Five features are **active** (the host sets their flags / sends their actions); two ship **dormant**.
+> **Confirm you're on the fork first:** EC iframe console prints `Element Call embedded-v0.20.1-lotus.1`
+> (the old build prints `embedded-v0.20.1`). If it says the old version, the web deploy hasn't landed —
+> the fork features won't be present, so don't test D2 yet.
+> For non-dev testers, each item below also states the plain "✅ good if / ❌ tell us if" outcome.
+
+### D2-1. Denoise **in-source** — survives reconnect (fixes A7) ⭐ highest risk (everyone's mic)
+
+Flag: cinny sets `lotusDenoiseSource=1` when ML denoise is selected (the old build-time getUserMedia
+shim is **removed**). This is the single change with the widest blast radius — test deliberately.
+
+- [ ] **Audio flows, no silence** with ML denoise on (baseline, also §D line 204).
+- [ ] **Reconnect (the A7 fix):** in a call with ML denoise on, kill network ~10 s (devtools → Offline)
+      so EC shows "Connection lost / Reconnect", then restore. **Mic still works AND still denoised**
+      afterward, **without** End+rejoin. _(This is the exact bug that was reintroduced then fixed; if it
+      regresses, mic dies on every reconnect.)_
+- [ ] **Mic device switch mid-call** (Settings → change microphone): audio keeps working (same
+      `restart()` path as reconnect).
+- [ ] **Mute → unmute** a few times: audio returns each time.
+- [ ] **Each model** if the picker offers them: `rnnoise` (default), `speex`, `dtln`, `deepfilternet` —
+      each loads + denoises, no silence. (All four are in-source now; DTLN runs at 16 kHz, others 48 kHz.)
+- [ ] **No double-processing:** audio isn't over-suppressed/artifacted (would mean the old shim is still
+      injected alongside the in-source engine).
+- **Rollback if bad for everyone:** revert the cinny deploy commit (restores the shim + `@element-hq` parity).
+
+### D2-2. Speaking + mute indicators from widget **events** (#2)
+
+Flag: `lotusCallState=1`. cinny now reads speaker/mute state from `io.lotus.call_state` events instead of
+scraping EC's DOM (DOM fallback retained). Overlaps **G1**.
+
+- [ ] **Speaking glow** lights the **correct** person when they talk (you, then your friend).
+- [ ] **PiP "All muted" / "You muted" badge** points at the right person and updates on mute/unmute.
+
+### D2-3. Focus camera **during a screenshare** (#4 / A5)
+
+Action: cinny sends `io.lotus.focus_participant` (the DOM `.click()` hack is gone). Overlaps **A5 / G2**.
+
+- [ ] Person A screenshares; Person B camera on; **MemberGlance → Focus camera** on B → B's camera is
+      spotlighted **alongside/over** the shared screen (not ignored).
+- [ ] Camera-**off** target = graceful (no error, no kick out of the screenshare).
+
+### D2-4. In-call avatar decorations (#6) — **NEW, beyond A6**
+
+Action: cinny pushes `io.lotus.decorations`. **A6 only covered the lobby roster** and called in-call EC
+tiles out of scope — that's now in scope.
+
+- [ ] A participant with a **Profile decoration** joins **camera off** → the decoration ring renders on
+      their **in-call video-tile avatar** (inside EC, not just the lobby), correctly sized/positioned.
+- [ ] Decoration tracks the right person across grid/spotlight layout changes; disappears when they leave.
+
+### D2-5. Native transparent background (#5)
+
+Flag: `lotusTransparent=1` (native, replacing the injected `background:none !important`).
+
+- [ ] Call background looks right — host wallpaper/surface shows through; **no** black box, bad
+      see-through, or layout breakage (also covered loosely by §D2 "looks right").
+
+### D2-7. In-Call Soundboard (#3 / P5-15) — 👥 2 people — **NEW**
+
+Flag: `lotusAudioInject=1`. A 🔔 **Soundboard** button now sits in the call controls bar (left group,
+next to the chat button). Clips are user-uploadable and sync across your devices like emoji packs.
+_Prereq:_ Settings → General → Calls → **Soundboard** must be ON (default on).
+
+- [ ] **Upload:** open the soundboard popout → **Upload** → pick a short audio file (mp3/ogg/wav, ≤ 1 MB).
+      It appears as a clip tile. (Too-big / too-many shows an error, doesn't crash.)
+- [ ] **Plays into the call:** with a second person in the call, click a clip. **They hear it**, and
+      **you hear it locally** too. ✅ good if both hear it; ❌ tell us if only one side does.
+- [ ] **Sync:** the uploaded clip shows up on your **other device**/session (account-data sync).
+- [ ] **Delete:** the ✕ on a tile removes it (everywhere, after sync).
+- [ ] **Off switch:** turn Settings → Calls → **Soundboard** off → the call-bar button disappears.
+- [ ] Injecting a clip does **not** mute/interrupt your mic or anyone else's audio.
+
+### D2-8. Call Quality Controls (#7 / P5-31) — 👥 2 people — **NEW**
+
+Action: `io.lotus.set_quality`. User settings in **Settings → General → Calls** (Microphone Bitrate,
+Screenshare Bitrate, Screenshare Framerate; all default **Auto**). Admin caps in **Room Settings →
+General → Voice → Call Quality Caps**.
+
+- [ ] **No regression at Auto:** with everything on **Auto**, calls/screenshare work exactly as before.
+- [ ] **User cap takes effect:** set Microphone Bitrate to **32 kbps**, rejoin/continue a call — audio
+      still flows (thinner is fine). Set Screenshare Framerate to **15 fps** and share your screen — it
+      still shares. ❌ tell us if any setting kills audio/screenshare.
+- [ ] **Applies mid-call:** changing a setting **during** a call takes effect without End+rejoin.
+- [ ] **Room-admin cap (admin needed):** as a room admin, set **Max Microphone Bitrate = 64 kbps** in
+      Room Settings → Voice. A member whose user setting is higher (e.g. 256) should be **clamped to 64**
+      (best-effort/UX — this is client-side; hard server enforcement is a separate follow-up).
+- [ ] Resetting a setting back to **Auto** removes the cap for the rest of the call.
+
+> Soundboard + quality are no longer "dormant" — if either does nothing, grab the **EC iframe console**
+> and check for `io.lotus.inject_audio` / `io.lotus.set_quality` rejections.
+
+### D2-9. Call Permissions — HARD server-side, cross-client (👥 2 people, admin) — **NEW**
+
+This is enforced by the `voice-limit-guard` on the server (re-signs the LiveKit JWT), so it applies to
+**every** client, not just Lotus Chat. Set in **Room Settings → General → Voice → Call Permissions**.
+_(Requires the guard deployed on LXC 151 — auto-deploys on a `matrix` repo push.)_
+
+- [ ] **Disable screenshare:** as admin, turn **Allow Screen Sharing** off. In a call, the
+      **screenshare button disappears** in Lotus Chat. ✅ good if no one can screenshare.
+- [ ] **Cross-client (the important one):** have someone join the **same room from stock Element / Element
+      X** and try to screenshare → the server **refuses** the track (it won't publish). This proves it's
+      not just our client hiding a button.
+- [ ] **Audio-only room:** turn **Allow Camera** off too → the camera button disappears and cameras are
+      server-blocked for all clients; **microphones still work**.
+- [ ] **⭐ Live kill (mid-call):** while someone is **actively screensharing**, an admin turns **Allow
+      Screen Sharing** off. Within a few seconds their screenshare should **stop for everyone** on its own
+      (no rejoin needed) — this is the server reconcile loop revoking it live. Works even if the sharer is
+      on stock Element. ✅ good if the share drops within ~3–5 s; ❌ tell us if it keeps going.
+- [ ] **Turning it back on** restores the ability to screenshare/camera (start a new share).
+- [ ] **No policy = no change:** a room with Call Permissions left on defaults behaves exactly as before.
+
+> If any D2 item fails, grab the **EC iframe console** (right-click the call → inspect the iframe) — a
+> widget-action/payload mismatch shows up there as a `io.lotus.*` rejection or a `MissingKey`/transport log.

-### L1. AFK auto-mute keeps the OS microphone indicator lit (N95) — 👥 live call
+### L1. AFK auto-mute releases the OS microphone indicator on mute (N95) — 👥 live call

-**Context:** `useAfkAutoMute.ts` calls `getUserMedia({ audio: true })` independently of Element Call's managed stream. When you mute in the Lotus UI, the LiveKit mic inside EC's iframe is muted via the widget API — but the separate `MediaStream` held by the AFK hook keeps its tracks running. The OS-level recording indicator (green dot on macOS, mic icon on Windows/Linux) therefore stays lit while your mic is muted.
+**Context (now FIXED):** `useAfkAutoMute.ts` opened its own `getUserMedia` level-monitor capture for the whole call, so the OS recording indicator (green dot on macOS, mic icon on Windows/Linux) stayed lit even when muted. The capture is now gated on the reactive mic-on state — it runs only while unmuted, so muting releases the stream.

-**To reproduce:**
+**To verify:**

 1. Enable **AFK auto-mute** in Settings → Calls and **join a call**.
-2. Manually **mute your mic** using the call controls.
-3. Check the **OS recording indicator** (macOS: green dot top-right of menu bar; Windows: mic icon in taskbar).
+2. Manually **mute your mic** using the call controls → the **OS recording indicator should clear** within ~a second.
+3. **Unmute** → the indicator should re-appear (capture re-acquired).
+4. Also confirm AFK still works end-to-end: stay unmuted and silent past the configured timeout → mic auto-mutes with the "muted after inactivity" toast, and the indicator clears.

-**Expected (current broken behavior):** the OS recording indicator stays on even though your Lotus mic shows muted.
-**Expected after fix:** the indicator should clear when you mute and re-appear when you unmute.
+### L2. Maskable PWA icon (N108) — Android install

-> **Note:** This is an **open bug** — no fix has been applied yet. Reproduce and confirm the symptom first. The fix involves stopping `MediaStream` tracks on mute and re-requesting `getUserMedia` on unmute (see LOTUS_BUGS.md N95 for full details). Once fixed, re-run this check to verify the indicator clears.
+1. On **Android Chrome**, install Lotus Chat as a PWA (Add to Home Screen).
+2. Look at the **home-screen icon**.
+
+**Expected:** the icon fills the adaptive-icon shape cleanly (the logo centered with safe-zone padding on the dark background), **not** clipped at the corners or floating in an odd box. Also worth a quick check in Chrome DevTools → Application → Manifest that the two `purpose: maskable` icons load without a 404 (this also validates the manifest's icon paths resolve in production — a pre-existing path convention I couldn't verify statically).

+## N. OIDC / Next-Gen Auth login (MSC3861) — P4-6
+
+The Lotus client can now sign into OIDC-native homeservers (ones that delegate
+auth to a Matrix Authentication Service / MAS), e.g. mozilla.org. lotusguild's
+own server is **not** MSC3861, so test EITHER against a **local MAS dev loop**
+(full setup in `dev/oidc-test/README.md` — docker-compose + Synapse `msc3861`
+delta + a `config.json` override) OR against **mozilla.org** with a real account.
+
+### N1. OIDC login flow (the core test) — needs a MAS homeserver
+
+1. On the login screen, select the OIDC homeserver (local `localhost:8008`, or `mozilla.org`).
+2. **Expected:** instead of the username/password form, a single **"Continue with single sign-on"** button appears (password + legacy-SSO are suppressed for that server).
+3. Click it → redirected to the provider's login page (MAS / `chat.mozilla.org`).
+4. Authenticate there → redirected back to `…/auth/oidc/callback` → a brief "Signing you in…" spinner → you land in the app, logged in.
+
+**Expected:** no console CSP violations; you reach the room list as the OIDC user.
+
+### N2. Session persists across reload (token storage)
+
+After N1, hard-refresh the page.
+**Expected:** you stay logged in — the OIDC session (access + refresh token + issuer/clientId/claims) was persisted (`cinny_refresh_token`, `cinny_oidc_*` keys in localStorage).
+
+### N3. Token refresh (long-lived session)
+
+Leave the session past the access-token lifetime (MAS default is short — or revoke the access token in the MAS admin UI to force a 401).
+**Expected:** the client refreshes transparently (no logout); the stored access token rotates (reactive 401 refresh via the wired `OidcTokenRefresher`).
+
+### N4. Logout revokes at the issuer
+
+Log out from Settings.
+**Expected:** back to login; OIDC tokens are revoked at the issuer's `revocation_endpoint` (best-effort) and all `cinny_*` / `cinny_oidc_*` keys are cleared. Logging back in works.
+
+### N5. Account-management deep-link
+
+Settings → Account.
+**Expected:** on an OIDC server a **"Manage account"** card appears (opens the provider's account page in a new tab). On a non-OIDC server (lotusguild) the card is **absent**.
+
+### N6. Non-OIDC regression — password login unchanged
+
+Log into **matrix.lotusguild.org** (password) and **matrix.org**.
+**Expected:** identical to before — username/password form (+ SSO button where offered). The OIDC path only activates when discovery advertises an issuer, so nothing changes for these servers.
+
+---
+
+## O. July 2026 batch — threads, notifications, math, search cache, audit wave
+
+Everything landed after the OIDC work. These mirror the checklists in `LOTUS_TODO.md` (§P3-8, §P4-1) and the outstanding-verification backlog below (P3-8/P4-1/P4-4/P4-8/N97a/AW-1…4). **⚠️ Threads change the main timeline** — thread replies no longer render inline; that's intended (see O1).
+
+### O1. Thread Panel (P3-8) — 👥 2 people help for live replies
+
+1. Hover a message → **Reply in Thread** (message menu). The right-side **thread panel** opens with that message as the root.
+2. Send text, an emoji, and a file upload into the thread; have the second person reply too.
+3. Reply to a reply _inside_ the panel.
+
+**Expected:** the panel shows the root at top + an "N replies" divider + the reply timeline (own composer at the bottom). Your sends appear immediately (pending → confirmed). A reply-to-a-reply is a proper thread reply. In the **main** timeline the replies do **not** appear inline — the root message instead shows a **"N replies · time"** chip. Clicking the chip (or a reply's thread indicator) opens the panel. **×** or **Escape** closes it; on mobile the panel is fullscreen. Scrolled up in a long thread → a **Jump to Latest** chip appears. Reload the page → the root/reply split persists; in an **encrypted** room the thread replies decrypt (not "Unable to decrypt").
+
+### O2. Per-thread notifications (P4-1, Slack-style) — 👥 2 people
+
+1. Have the second person reply in a thread **you have posted in** → expect a notification + sound.
+2. Have them reply in a thread **you have never touched** and don't @mention you → expect **silence** (only the chip's unread badge updates).
+3. Have them **@mention** you in any thread → expect a notification regardless of participation.
+4. Open the panel's **bell menu** (header) → set the thread to **Mute** → expect no notifications, the chip's unread badge gone (bell-mute glyph shown), and the room's **sidebar badge drops** by that thread's count. Try **All** (every reply notifies) and **Mentions only** (only @mentions).
+5. On a **second device**, confirm the same per-thread modes are set (they sync via account data).
+6. Room-level **Mute** (room context menu) still silences everything, including thread overrides.
+
+**Known caveat:** Mentions-only can under-notify in E2EE rooms (the decision runs before decryption). Muted-thread badge subtraction is Lotus-only.
+
+### O3. Math / LaTeX (P4-4)
+
+Send each and confirm rendering: `$x^2 + y^2$` (inline), `$$\int_0^1 f(x)\,dx$$` (block, centered), `$5 and $10 for lunch` (**stays plain text** — currency guard), and a code block containing `$x$` (**stays literal** inside the code block). **Expected:** the first two render as math (KaTeX); the last two are untouched. First math of the session may show the raw `$…$` for a beat while the KaTeX chunk lazy-loads, then renders.
+
+### O4. Encrypted search cache (P4-8) — opt-in
+
+In an **encrypted** room's message search, enable **"Persist search index on this device"** (Encrypted Rooms panel). Search, then **reload** and search the same term. **Expected:** coverage survives the reload (results without re-paginating everything). **Clear cached index** empties it. **Log out** → the cache is wiped (privacy). Toggling the setting OFF does **not** wipe (only Clear/logout do).
+
+### O5. Session hardening (N97a) — cross-tab
+
+1. Log in on a build that predates the change, then load this build → you stay logged in (legacy keys migrate to the `cinny_session_v1` blob; check DevTools → Application → Local Storage).
+2. Open the app in **two tabs**; **log out** in tab A → tab B reloads to the auth screen within a moment. Log in again in one tab → the other reloads too.
+
+### O6. Audit-wave correctness fixes (AW-1)
+
+- **Scheduled-message cancel:** schedule a message, then cancel it **with the network cut** (DevTools offline) → the item **stays** with an inline error (it does **not** silently disappear and still send). Restore network, retry → cancels cleanly.
+- **Escape coordination:** in a thread panel, open the mention autocomplete or set a reply draft, press **Escape** → it dismisses the autocomplete/reply **without** closing the panel. A bare Escape (nothing to dismiss) still marks the room read / closes the panel as before.
+- **Panel exclusivity:** on mobile, opening a thread while the media gallery (or members drawer) is open shows only **one** right panel (thread wins), not stacked fullscreen overlays.
+- **Emoji board (AW-2):** the **first** time you open the emoji board / autocomplete in a session, the grid **and search** populate with unicode emoji (they don't stay empty). Reactions still show a label.
+
+### O7. Desktop (Tauri) — CSP tighten + native stack (AW-4) — 🖥️ desktop build only
+
+The webview CSP was tightened and the full native module set now compiles. Smoke-test the desktop build:
+
+1. App **boots**, avatars + media thumbnails load, the **VT323** terminal font renders (Lotus Terminal theme), a **location message** embeds its OpenStreetMap map, **calls** connect (EC iframe), **deep links** (`matrix:` / clicking a room link) navigate.
+2. **Native features:** minimize to tray (notifications still arrive), a message notification is a **rich toast** (click opens the room; reply box sends), the taskbar **Jump List** lists recent rooms, in a call the taskbar thumbnail shows **Mute/Deafen/End**, Windows **Focus Assist** silences Lotus.
+3. **Console** (desktop devtools) shows **no CSP violations** during normal use. If something visual/media is blocked, that's the CSP to loosen — note exactly what and where.
+
+### O8. E2EE / call-key cluster (KE-1→4) — 👥 2 people, during a real call
+
+We shipped the diagnostics kit + a **Crypto Diagnostics** card (**Settings → Developer Tools**). During your next call that glitches (audio cutouts, "Unable to decrypt"), open it and **Download report**, and note whether the symptoms even still occur now that we're on **matrix-js-sdk 41.7.0** (crypto-wasm 18.3.1). Send me the report; the KE-1..4 diagnosis + capture guidance is in `LOTUS_TODO.md` (Encryption / E2EE), with the full original runbook in git history.
+

+
+## P. Accessibility (P3-4) — needs a browser + a screen reader
+
+The compliance fixes are gate-verified in code; these confirm the runtime a11y behavior only a human + AT can check. Tools: browser DevTools "axe" extension / Lighthouse a11y, plus **VoiceOver** (macOS ⌘F5) or **NVDA** (Windows).
+
+### P1. Keyboard-only golden path (no mouse)
+
+Tab from page load: **skip-to-content** link appears first (Enter jumps to the timeline). Tab reaches the room list (rooms are focusable, active room announced), open a room (Enter), type a character → focus lands in the composer, send with Enter (or Shift+Enter per your `enterForNewline` setting). No keyboard trap; visible focus ring throughout.
+
+### P2. `?` shortcuts dialog
+
+Press **?** (Shift+/) with focus NOT in a text field → the keyboard-shortcuts dialog opens, is focus-trapped, Escape closes it and focus returns to where you were. Pressing `?` while typing in the composer/search inserts a literal `?` (does NOT open the dialog).
+
+### P3. Screen-reader: reading messages
+
+With VoiceOver/NVDA on, arrow through the timeline: each message is announced as an article with **sender name + time** — critically, this includes **collapsed messages** (consecutive messages from the same person), which previously announced only the body with no sender. Reactions, "edited", replies, and delivery status are announced with labels.
+
+### P4. Screen-reader: live announcements
+
+- **New message** arrives while you're reading → announced (polite).
+- **Someone starts typing** → "X is typing" announced once (not spammed per keystroke).
+- **Editing a message** → the edit box announces "Editing message from X".
+
+### P5. Focus return from dialogs
+
+Open then close (Escape or ×): the **room topic viewer**, a **reaction viewer** (click a reaction count), and **Search** → focus returns to the button/element you opened them from (not lost to `<body>`). Inline popouts (emoji picker, autocomplete, hover menus) intentionally keep focus in context — that's expected, not a bug.
+
+### P6. axe / Lighthouse scan
+
+Run the axe DevTools extension (or Lighthouse → Accessibility) on a room view, Settings, and the login screen. Expect **no critical/serious** "missing accessible name" or "ARIA" violations on the golden path. Report any that appear (note: far-scrolled timeline history being virtualized out is a known, accepted limitation — not a finding).
+
+---
+
+## Q. Inline Media Embeds — video / audio / post players (needs the web deploy live)
+
+The whole feature is behind **Settings → General → "Inline Media Players"** (default **on**). Everything loads from the homeserver's cached thumbnail first; the third-party player only mounts on **Play**. Test on the **web** build first, then re-check the video ones on **desktop (Tauri)** since the CSP differs. On any failure, grab the **browser console** (F12) — a blocked embed shows as a CSP `frame-src` violation naming the host.
+
+### Q1. Facade + one of each kind plays in place
+
+Paste each of these into a room and confirm a media tile (not a plain link) with a thumbnail + play button, and that clicking Play mounts the player **inline**:
+
+- **16:9 video:** a YouTube `watch` link, a Vimeo link, a Dailymotion link, a Streamable link, a Twitch VOD/clip, a Loom `share` link.
+- **9:16 portrait:** a YouTube **Shorts** link (renders tall, not letterboxed).
+- **Audio player:** a Spotify track, a SoundCloud track, an Apple Music album, a Tidal album/track.
+- **Post embed:** an X/Twitter post, an Instagram post, a Reddit post.
+
+**Expected:** ✅ tile shows the thumbnail; **no** request to the third party until you press Play (check DevTools → Network); the player then plays inline. ❌ tell me any that stay a plain link, show a blank frame, or hit the network before you click.
+
+### Q2. TikTok (the tricky one) + portrait fill
+
+1. Paste a **full** TikTok URL and a **short** copy-link (`vm.tiktok.com/…` or `tiktok.com/t/…`).
+2. Press Play on each.
+
+**Expected:** both resolve to a clean **9:16** player that **fills the box** (no big empty band on the right). The short link shows a brief spinner while it resolves via oEmbed, then plays. ❌ tell me if a short link shows only the TikTok logo/♫ and never a play button, or if the player has dead space beside it.
+
+### Q3. Post self-resize + Close / Fullscreen controls
+
+1. Play a **Reddit**, **Instagram**, and **X/Twitter** post embed.
+2. Watch the card height as the embed loads.
+
+**Expected:** the card **grows to fit** the post (no clipped/scrollbarless content, no giant empty box). A **Close** button (✕) collapses the player back to the thumbnail; video players also show a **⛶ Fullscreen** control that works. Keyboard: Tab to the play button → it shows a visible **focus ring**.
+
+### Q4. New providers (unverified) + the toggle + the cap
+
+- **Bluesky / Loom / Kick** — these are freshly added and unverified live. Paste a `bsky.app/profile/…/post/…`, a `loom.com/share/…`, and a live `kick.com/{channel}` link. ✅ good if each plays/renders inline; ❌ if any is a broken frame (for **Bluesky** especially, note whether a **handle** URL resolves or only a DID one does — grab the console).
+- **Toggle off:** Settings → General → **Inline Media Players** off → every media link reverts to a plain link tile (no player).
+- **Cap:** paste a message with **8+** media links → at most **6** preview cards render (the rest are suppressed), and the page stays responsive.

+
+## R. Discovery-pass fixes (DP1–DP18, 2026-07)
+
+Agent-surveyed + TPVR-verified low/med issues, now fixed (commits `8eb961b6` `db864326` `6cf18c3b` `165714e1` `8c0e2b42` `e545706c` `b1ee3ada` `4fc3f7a3` `101e4116` `4fa4327a` `c2598d21`). Behavioral items have concrete checks; the refactors just need a "still works" regression pass.
+
+### Correctness
+
+- [ ] **DP1 — slash-command errors are visible.** Run a slash command that must fail — e.g. `/kick @nobody:server` in a room where you lack permission, or `/join` a bad alias. **Expected:** an error toast appears (not a silent no-op); a successful command still clears the composer normally.
+- [ ] **DP2 — no invite re-notify on reload.** With ≥1 pending invite, hard-reload (Ctrl+F5). **Expected:** NO "you have N new invitation" toast/sound on load. Then have someone invite you while the app is open → you DO get one notification for the new invite. (👥 2 accounts)
+- [ ] **DP3 — status clear syncs across devices.** Set a status message on device A, confirm it shows on B; clear it on A. **Expected:** B clears too and does NOT re-publish the old status on its next presence heartbeat. Toggling Invisible must not wipe a real saved status. (👥 2 sessions)
+- [ ] **DP4 — tag-toggle failure surfaced once.** With the network offline, toggle a room's Favourite/Low-priority. **Expected:** a single error toast (not two) on failure; on success the tag updates as before.
+- [ ] **DP5 — soundboard packs update on room switch.** Open a soundboard in room A, then switch to room B (different pack) in the same mounted view. **Expected:** B's packs show without needing an unrelated event.
+- [ ] **DP6 — declining a call still dismisses.** Decline an incoming call. **Expected:** the ringing UI dismisses even if the decline send fails (best-effort). (👥 2 accounts)
+
+### a11y / UX (needs a screen reader + a narrow viewport)
+
+- [ ] **DP7 / DP8 — call-control buttons announce correctly.** In a call with a screen reader: the deafen button announces "Deafen" when sound is on (not "Undeafen"); Sound / Video / Screenshare announce a consistent pressed/unpressed state like Mic.
+- [ ] **DP9 — GIF picker focus + width.** Open the GIF picker, close it (Esc / click-out) → focus returns to the GIF button. On a ~320px viewport the picker doesn't overflow the page.
+- [ ] **DP10 — search-filter clears by keyboard.** In message search, toggle a filter chip (Has link / msg-type / pinned) off with Enter; the date-range clears via its menu's Clear. No mouse-only clear needed.
+- [ ] **DP11 — voice recorder fits + announces.** On a ~360px viewport, start a voice message → the recorder row doesn't overflow the composer; a screen reader can query the duration (role="timer") without being spammed.
+- [ ] **DP12 — live-call count announced.** With a screen reader, when someone joins/leaves an active call, the "{n} Live" change is announced (polite status region).
+
+### TDS colors (Lotus Terminal theme)
+
+- [ ] **DP14 — send-status + receipt colors follow the theme.** In **TDS light** mode: the message send-status "failed" icon and the read-receipt pill use the theme's darker red/blue (from `--lt-*` tokens), NOT bright dark-mode cyan/red. TDS dark still looks right; non-TDS themes unchanged.
+
+### Refactor regression pass (no behavior change intended)
+
+- [ ] **DP13 — bookmarks / reminders / notes still work** (they now share one store engine). Add/remove a bookmark, set/clear a reminder, write/clear a user note; each persists across reload; rapid consecutive writes don't clobber each other.
+- [ ] **DP15 / DP16 — state-event + account-data writes still work.** Edit room name/topic/avatar, join-rules, power levels, an emoji/soundboard pack (state events); toggle a setting stored in account data. All save + reflect correctly.
+- [ ] **DP17 — link previews render.** Open a TikTok / Spotify / Steam / Reddit link preview; provider icons render (folds icons, not raw glyphs) and brand colors look right.
+- [ ] **DP18 — member avatars/names live-update.** Read receipts + the "seen by" reader list show correct avatars/names and update live when a member changes their avatar or display name (no reload).
+

 ## Priority if you're short on time

-1. **A4** (in-call banner) + **A3** (ringtone) — newest, most logic, hardest to reproduce.
-2. **B1–B3** (polls on a default theme) — the confirmed visual bug.
-3. **D** (EC 0.20.1 control sweep) — guards against the upstream merge breaking calls.
-4. **A7** false-positive check (normal joins don't show the error overlay).
-5. Everything else.
+1. **O1 + O2** (threads + per-thread notifications) — the largest new surface; the main-timeline change is user-visible.
+2. **O7** (desktop CSP smoke) — CI can't catch CSP breakage; a wrong directive silently breaks media/fonts/maps.
+3. **O5** (session cross-tab) + **O6** (scheduled-cancel ghost-send) — auth-critical + a real data-loss-class fix.
+4. **A4** (in-call banner) + **A3** (ringtone) — newest call logic, hardest to reproduce.
+5. **D** (EC control sweep) — guards against the fork breaking calls.
+6. Everything else.

+
+## Outstanding verification backlog
+
+**Room Widgets (MSC1236, 2026-07 — needs the CSP `frame-src` widening + `nginx -s reload` first):** In a room, the header **Widgets** button (grid icon, desktop) opens a right-side panel. As an admin (PL to modify widgets): **Add Widget** with a name + an https URL (e.g. an Etherpad `https://…` or any embeddable page) → it appears in the list; click it → it renders in a sandboxed iframe in the panel; **Remove** clears it. A non-admin sees the list + can open widgets but has no Add/Remove. Check: a non-https or same-origin URL is rejected on Add with a clear message; the panel is a full-screen overlay on mobile and is mutually exclusive with the Thread/Gallery/Members panels; if a widget stays blank, the prod CSP `frame-src` still needs widening. Widgets get only benign display capabilities (they can't send/read room events in v1).
+
+**QR Device Verification (2026-07):** With two logged-in Lotus sessions (or Lotus + Element), start a device verification. On the **Ready** step you now see your own QR code plus a **"Scan their QR code"** button and a **"Verify with emoji instead"** fallback. Have one device **scan** the other's code (grant camera permission) → the showing device asks you to **Confirm**, and both reach **verified**. Check: emoji-SAS still works unchanged; denying camera shows a graceful "verify with emojis instead" message; a deliberately-wrong scan cancels cleanly. Desktop (WebView2) auto-grants the camera; web needs the Permissions-Policy camera allowance (already set).
+
+**Disappearing Messages (MSC1763 `m.room.retention`, 2026-07):** In Room Settings → General → **Message Retention**, an admin picks Off / 1 Day / 1 Week / 1 Month (non-admins see the buttons disabled). After setting e.g. 1 Day, messages older than a day **vanish from the timeline** for everyone in Lotus (toggle Settings → General → **Show Hidden Events** to reveal them again). Setting back to **Off** restores them. Separately, each user can enable Settings → General → **Enforce Message Retention** (default OFF) → their OWN expired messages then get **permanently redacted** within ~30 s (verify: OTHER people's messages are NEVER redacted by this; only your own). Note true server-side purge also needs Synapse `retention:` configured.
+
+**Mark as Unread + Low Priority (MSC2867 / m.lowpriority, 2026-07):** Right-click a room in the sidebar → **Mark as Unread** puts a dot on the row (bold name) even with no new messages; opening/reading the room clears it, and it syncs to another device. **Mark as Read** on a marked room clears it too. Right-click → **Add to Low Priority** moves the room into a collapsed "Low Priority" category at the bottom of the room list (and removes it from Favorites if it was there, and vice-versa); **Remove from Low Priority** returns it to Rooms.
+
+**Windows rich toast (D6, 2026-07 — desktop/Windows build only):** get a message notification while the desktop app is backgrounded → the toast is attributed to **Lotus Chat** (not "PowerShell"/generic) and shows an inline **reply box + Send**; typing a reply + Send **posts it to that room**; clicking the toast body **opens the room**. Previously these silently fell back to a plain toast (no reply/click). If it still falls back, check that a `Lotus Chat.lnk` exists in the Start-Menu Programs folder.
+
+**Invite QR is now generated LOCALLY (2026-07):** Room settings → Share Room → the QR code renders (a black-on-white SVG in a white box) with **no network request** to `api.qrserver.com` (check DevTools Network — there should be no external QR fetch, and it should work offline / behind strict CSP). **Scan it** with a phone camera / Matrix app → it opens the correct `matrix.to` room-invite link. (`api.qrserver.com` was removed from the prod CSP img-src, so a regression would make the QR blank rather than silently phone home.)
+
+**Unread dot on federated rooms + avatar-decoration console storm (2026-07):**
+
+- **Read receipts (regression guard — highest priority):** open several rooms and open the Home/Direct tabs (which mark all orphan rooms read on mount) → rooms **stay read**, unread dots clear and don't come back. (A prior attempt sent a receipt for the thread _root_ when a thread's replies weren't loaded, which the SDK treats as a main receipt at an old event and re-unread every room on every mark-read. Fixed + locked by `notifications.test.ts`.)
+- **Thread dot:** a room with an unread reply in a thread whose replies are loaded → its dot clears on read; for a thread not yet loaded, the dot clears once you open/load the thread. (mark-as-read now sends a threaded receipt only for a genuine loaded reply, never the root.)
+- With DevTools console open on federated rooms, the `io.lotus.avatar_decoration` `403`/`502` (and federated media) errors should **not** repeat on every scroll/mount — each failing user is now requested at most ~twice per session, so the storm (and its homeserver load) is gone.
+
+**Custom Window Chrome (Beta) fix (2026-07):** on the desktop build, Settings → General → toggle **Custom Window Chrome** — it should reload and come up with the Lotus title bar and a normal, stable feed (no screen-expand / auto-scroll-into-the-past). Toggle back off → reloads to the native frame.

+## Development Environment Setup
+#### Getting correct Node version
+- Ensure you have the correct version of node installed, specified in `.node-version`
+- Use this command from the terminal to install nvm 
+```bash
+curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.3/install.sh | bash
+``` 
+- Reload your terminal shell using (for Ubuntu):
+```bash
+source ~/.bashrc
+```
+- Install the specified Node version 
+```bash
+NODE_VERSION="$(tr -d '[:space:]' < .node-version)"
+nvm install "$NODE_VERSION"
+nvm use "$NODE_VERSION"
+```
+- verify the correct version was installed by running
+```bash
+node --version
+```
+and comparing the output to what is listed in `.node-version`
+#### Install npm packages
+- To install the npm packages listed in `package.json` run: 
+```bash
+ npm i 
+ ```
+### Start Development Server
+```bash
+npm run start
+```
+You should now have an active development server at `localhost:8080`, where you can make changes to the code and see the UI update in real time
 ## Features

 ### Messaging

+- Threads: reply in a thread and read/write the whole conversation in a side panel — root messages show a "N replies" chip with an unread badge (threaded replies live in the panel now, not inline in the room)
+- Slack-style thread notifications: by default you're only pinged for threads you're in or where you're @mentioned; set any thread to All / Mentions-only / Mute from the panel's bell menu (muted threads stop bumping badges; syncs across devices)
 - See who has read each message, and track delivery status (sending / sent / failed)
 - Bookmark any message and revisit saved messages from the sidebar
 - Schedule messages to send at a specific time

+### Local Development
+
+Lotus Chat is a **pure client — there is no backend of its own to run.** It talks directly to a Matrix homeserver (Synapse) over HTTPS, so the only thing you run locally is the Vite dev server; it connects to a real homeserver for all data. If you were looking for "the backend to pair with it," there isn't one — that's the homeserver.
+
+**Prerequisites:** Node 20+ (CI builds on Node 24) and npm.
+
+```bash
+npm ci        # deps; @lotusguild/* come from our Gitea npm registry (public read — no auth/token needed)
+npm start     # Vite dev server → http://localhost:8080
+```
+
+The dev server defaults to **port 8080** (`vite.config.js`); if 8080 is already in use it falls through to 8081+, so check the "Local:" URL Vite prints on startup. If it boots but the page renders blank, it's almost always a failed module/asset resolution, not a "missing backend" — open the devtools console and read the first error.
+
+**Which homeserver / logging in:** `config.json` sets `defaultHomeserver: 0` → `matrix.lotusguild.org`, so you sign in with your normal `@you:matrix.lotusguild.org` account. That homeserver is **live production** — anything you send is real, so keep test traffic to a DM with yourself or a throwaway room. To develop fully isolated instead, point `config.json` at a throwaway `matrix.org` account (already in `homeserverList`) or a local Synapse.
+
+- **SSO / OIDC works from localhost.** Login goes through Authelia via OIDC dynamic registration; the provider redirects back to `http://localhost:8080/…` and the client registers that redirect on the fly, so no server-side allow-listing is needed. After the callback you may see a `GET …/_matrix/media/v1/thumbnail/… 404` — that's just a missing avatar thumbnail, **not** a login failure.
+
+### 🔱 Element Call fork ("Lotus Call") — LIVE
+
+Voice/video channels embed **Element Call**, which is now our **self-built fork**
+(`@lotusguild/element-call-embedded` `0.20.1-lotus.1`, source at
+`LotusGuild/element-call`), published to our private Gitea npm registry and served
+same-origin. We no longer depend on the upstream prebuilt bundle, so in-call
+behavior is editable source instead of fragile DOM/widget hacks.
+
+**Shipped via the fork:** denoise as an in-source LiveKit audio stage (survives
+reconnects), in-call speaking/mute events, focus-a-participant during screenshare,
+avatar decorations on EC video tiles, and a native transparent background.
+**Built but dormant (need cinny UI):** real call-audio injection
+(`io.lotus.inject_audio` → in-call soundboard) and quality controls

+# Local OIDC / next-gen-auth (MSC3861) test loop
+
+The Lotus client gained MSC3861/MSC2965 OIDC login (P4-6). lotusguild's own
+homeserver is **not** MSC3861, so to exercise the flow without a mozilla.org
+tester you need a local homeserver that delegates auth to a **Matrix
+Authentication Service (MAS)**. This is the dev loop.
+
+> Status: the Lotus-client side is unit-tested + gate-green; this server loop is
+> the manual end-to-end check. It hasn't been run in CI (no container runtime
+> there), so treat version pins as a starting point and bump as needed.
+
+## 1. Stand up MAS + Synapse
+
+The simplest path is the **upstream MAS docker-compose quickstart** — it's
+maintained and handles key generation + the database:
+<https://element-hq.github.io/matrix-authentication-service/setup/installation.html>
+(`docker compose` section). Use it to get MAS + Synapse + Postgres running, then
+apply the two Lotus-specific deltas below.
+
+A minimal `compose.yaml` skeleton (generate MAS keys first — do **not** hand-write them):
+
+```yaml
+services:
+  postgres:
+    image: postgres:16
+    environment: { POSTGRES_USER: synapse, POSTGRES_PASSWORD: pw, POSTGRES_DB: synapse }
+  mas:
+    image: ghcr.io/element-hq/matrix-authentication-service:latest
+    command: server
+    ports: ['8090:8080'] # MAS issuer on http://localhost:8090
+    volumes: ['./mas:/data']
+    # First run once: `docker compose run --rm mas config generate -o /data/config.yaml`
+    # then edit /data/mas/config.yaml (see §1a) before `up`.
+  synapse:
+    image: ghcr.io/element-hq/synapse:latest
+    ports: ['8008:8008'] # client/federation API
+    volumes: ['./synapse:/data']
+    depends_on: [postgres, mas]
+```
+
+### 1a. MAS `config.yaml` — the parts that matter
+After `config generate` (which fills in `secrets.keys` + `encryption`), set:
+
+```yaml
+http:
+  public_base: http://localhost:8090/
+  issuer: http://localhost:8090/
+database:
+  uri: postgresql://synapse:pw@postgres/synapse
+matrix:
+  homeserver: localhost          # the server_name
+  endpoint: http://synapse:8008/
+  secret: "REPLACE_WITH_A_LONG_SHARED_ADMIN_TOKEN"
+clients:
+  - client_id: "0000000000000000000SYNAPSE"
+    client_auth_method: client_secret_basic
+    client_secret: "REPLACE_WITH_A_SHARED_CLIENT_SECRET"
+passwords:               # so you can create a local test account in the MAS UI
+  enabled: true
+```
+
+### 1b. Synapse `homeserver.yaml` — delegate auth to MAS
+See `synapse-msc3861.yaml` in this folder; the key block is:
+
+```yaml
+experimental_features:
+  msc3861:
+    enabled: true
+    issuer: http://localhost:8090/
+    client_id: "0000000000000000000SYNAPSE"
+    client_auth_method: client_secret_basic
+    client_secret: "REPLACE_WITH_A_SHARED_CLIENT_SECRET"   # == MAS clients[].client_secret
+    admin_token: "REPLACE_WITH_A_LONG_SHARED_ADMIN_TOKEN"  # == MAS matrix.secret
+    account_management_url: "http://localhost:8090/account"
+```
+
+Create a test user via the MAS UI (`http://localhost:8090/`) or
+`docker compose exec mas mas-cli manage register-user`.
+
+Sanity check discovery (the client relies on this):
+```bash
+curl -s http://localhost:8008/.well-known/matrix/client | jq '."m.authentication"'
+# -> { "issuer": "http://localhost:8090/", "account": "http://localhost:8090/account" }
+```
+
+## 2. Point the Lotus dev client at it
+
+Run the client: `npm start` (vite dev). Override `public/config.json` so the
+local server is selectable and custom servers are allowed:
+
+```json
+{
+  "defaultHomeserver": 0,
+  "homeserverList": ["localhost:8008"],
+  "allowCustomHomeservers": true,
+  "hashRouter": { "enabled": false, "basename": "/" }
+}
+```
+
+Dynamic client registration handles the redirect URI automatically — it's
+`<vite-origin>/auth/oidc/callback` (e.g. `http://localhost:5173/auth/oidc/callback`),
+and MAS allows `http://localhost` redirects in dev.
+
+## 3. Run the checklist
+
+See **section N** of `../../LOTUS_TESTING.md` for the actual pass/fail steps
+(login redirect, callback, session-persist-on-reload, token refresh, logout
+revocation, account-management link, and the non-OIDC-regression check).

+ * ArcadeOverlay — retro synthwave CRT.
+ *
+ * A full-screen, pointer-events:none ambient decoration. The parent supplies a
+ * fixed inset:0 overflow:hidden pointer-events:none container at the correct
+ * z-index, so this component only returns absolutely-positioned aria-hidden
+ * children and never sets position:fixed / z-index / pointer-events.
+ *
+ * Composition (back to front):
+ *   1. near-black synthwave ambient wash (magenta sky-glow up top, cyan/purple
+ *      pool toward the floor) — layered oklch gradients for depth
+ *   2. a neon perspective grid receding to a vanishing point on the horizon,
+ *      scrolling toward the viewer via transform translateY (never bg-position)
+ *   3. a soft horizon sun-glow + thin neon horizon line where the grid meets sky
+ *   4. drifting pixel sparkles / neon coin-burst specks rising off the grid
+ *   5. fine CRT scanlines, gently rolling
+ *   6. a faint chromatic-aberration fringe at the screen edges
+ *   7. a glowing "INSERT COIN" blip + a corner SCORE HUD glyph
+ *   8. a CRT vignette + screen-glow that frames and protects central text
+ *
+ * All motion is transform/opacity only (compositor-friendly). When `reduced` is
+ * true we render a static-but-gorgeous scene: a still neon grid, steady
+ * scanlines + vignette, and a steady "INSERT COIN" — no `animation` anywhere,
+ * no flicker. The settings preview always passes reduced=true, so the still
+ * form stands on its own.
