i hate npm audit

The forked-in Cinny issue setup funneled reporters to the upstream project:
- config.yml disabled blank issues and linked to cinnyapp/cinny GitHub
  Discussions
- preapproved.md was Cinny's "do not open an issue, use Discussions"
  template (Gitea has no Discussions anyway)

Replace it with a Lotus setup: enable blank issues, drop the upstream
contact link, and add Bug Report + Feature Request templates. Now
/issues/new/choose offers Lotus templates and files against this repo.

-## 🚩 Critical & UI Bugs
-
-### 12. PiP Mute Icon Misidentifies Whose Mic Is Muted
-
-- **File:** `cinny/src/app/components/CallEmbedProvider.tsx`
-- **Status:** **FIXED ⚠️ UNTESTED** — needs verification in a live call with at least one other participant who mutes/unmutes
-- **Issue:** The muted-mic badge in the Picture-in-Picture window used `useRemoteAllMuted` (fires when ANY remote participant is muted) and rendered in the bottom-left corner — the conventional position for "YOUR" mic status. Users read it as their own mic being muted.
-- **Root Cause:** `PipMuteOverlay` was triggering on remote-mute events while displaying in a position that implies local-user status.
-- **Fix Applied:**
-  - **Bottom-left badge** now shows only when the LOCAL user's mic is muted (checked via `!controlState.microphone` from `useCallControlState`). Includes "You" label to make it unambiguous. Uses `color.Critical.Main`.
-  - **Top-right badge** (new) shows "All muted" in `color.Warning.Main` when all remote participants are muted — positioned and labeled so it's clearly about other people, not the local user.
-  - Both badges use `aria-label` / `title` for accessibility.
-

-
-### 1. No Camera Focus During Screenshare
-
-- **File:** `cinny/src/app/plugins/call/CallControl.ts`, `cinny/src/app/features/call-status/MemberGlance.tsx`
-- **Status:** **FIXED ⚠️ UNTESTED** — needs verification in a live call with an active screenshare + a participant on camera
-- **Issue:** Automatic screenshare spotlighting forces primary display override, preventing users from manually focusing on camera feeds.
-- **Root Cause:** Before this feature there was no UI path to manually pick a camera to focus, so EC's auto-spotlight (which prioritizes an active screenshare) always won.
-- **Fix Applied:** `CallControl.focusCameraParticipant(userId)` switches EC to spotlight mode and clicks that participant's `[data-testid="videoTile"]` inside the EC iframe — in Element Call, clicking a tile in spotlight **pins** it, so the user's explicit selection takes precedence over the auto-pinned screenshare. Exposed via a "Focus camera" item in the `MemberGlance` participant menu (avatar → menu). Falls back to a plain spotlight toggle if the tile isn't rendered (e.g. camera off).
-- **Architectural note:** EC owns the grid/spotlight renderer inside its iframe; our control is DOM-level tile clicks. The pin persists until changed, so a one-shot focus is sufficient. A continuously-enforced "sticky" focus that re-pins on every EC spotlight change was deliberately **not** built — it would require fighting EC's internal state on each mutation and risks flicker.
-
-### 2. Chat Background Animation Flickering
-
-- **File:** `cinny/src/app/features/lotus/chatBackground.ts`
-- **Status:** **FIXED ⚠️ UNTESTED** — needs verification on a real device with an animated background active
-- **Issue:** Animated background properties cause visible flickering on message text and the composer area, particularly on browsers/GPUs susceptible to repaint-induced artifacts.
-- **Root Cause:** Animation triggers excessive repaints or layout recalculations on descendant elements, likely due to animating non-GPU accelerated properties on parent containers without proper rendering context isolation.
-- **Fix Applied:** `getChatBg()` now injects `willChange: 'background-position'` and `contain: 'paint'` for any animated variant. This promotes the element to its own compositor layer and isolates repaints from descendants. Background-position animation is already GPU-hinted on modern browsers; `contain: paint` prevents descendant elements from being invalidated during each frame.
-
-### 3. Avatar Decorations in Element Call
-
-- **File:** `cinny/src/app/features/call/CallMemberCard.tsx`
-- **Status:** **FIXED ⚠️ UNTESTED** — needs verification in a live call with a participant who has a decoration set
-- **Issue:** Avatar decorations are failing to render within the call/room interface member lists.
-- **Root Cause:** Member lists and the people drawer already wrapped avatars in `<AvatarDecoration userId={...}>`, but the call participant tile (`CallMemberCard`) rendered a bare `<UserAvatar>` with no decoration wrapper — so decorations were absent specifically on call tiles. (Note: avatars rendered _inside_ the Element Call iframe are EC-rendered and out of our control; this fix covers our own participant roster / prescreen.)
-- **Fix Applied:** Wrapped the call-tile avatar in `<AvatarDecoration userId={userId}>` (commit `0394fce9`), matching the member-list pattern.
-
-### 4. DM and Group Message Calls
-
-- **File:** `cinny/src/app/components/CallEmbedProvider.tsx`
-- **Status:** **FIXED ⚠️ UNTESTED** — needs live-call verification: (a) ring/preview per selected ringtone & volume; (b) the corner banner appearing (with a single ping, not a loop) when a second call arrives while already in a call.
-- **Issue:** Incoming call ringtone is hardcoded, lacks volume control, and is suppressed if the user is already in an active call.
-- **Root Cause:** Ringing logic is tightly coupled to `RTCNotification` events in `CallEmbedProvider.tsx`, using a hardcoded audio file path. It lacks an abstraction for sound management or user-configurable settings for ringtones/volumes.
-- **Fix Applied:**
-  - `ringtoneVolume` setting (0–100, default 70); applied to the ring. Slider in Settings → General → Calls.
-  - **(a) Ringtone selection** (`4a875884`): `ringtoneId` setting (`classic | chime | soft | retro | none`). New `utils/ringtones.ts` synthesizes the three styles in-browser (WebAudio, mirroring `callSounds.ts`) — no new binary assets; `classic` keeps `call.ogg`; `none` is silent/visual-only. `startRingtone()` loops until stopped; `previewRingtone()` powers the on-select preview in Settings. Persisted id is whitelisted in `getSettings`.
-  - **(b) Active-call notification** (`c67aed01`): when already joined to a _different_ call, a compact, non-intrusive `IncomingCallBanner` (caller avatar + name + Answer/Reject, top-right) replaces the full-screen `IncomingCall` overlay and plays a **single soft ping** (one-shot ringtone) instead of the looping ring — so it never takes over the screen or talks over the active call. Full overlay still shows when in no call; being in the ringing room's own call still shows nothing.
-
-### 5. Seasonal Themes and Chat Backgrounds Design
-
-- **File:** `cinny/src/app/hooks/useTheme.ts`, `cinny/src/app/features/lotus/chatBackground.ts`
-- **Status:** **OPEN**
-- **Issue:** Basic CSS or random moving lines are insufficient for high-fidelity wallpaper/theming. They lack professional design theory, coherence, and aesthetic depth.
-- **Root Cause:** Current implementation relies on basic CSS, lacks advanced design theory, and does not leverage modern, performant CSS wallpaper techniques.
-- **Proposed Fix (Extreme Depth Redesign):**
-  - **Research-Backed Implementation:** Implement advanced design techniques (layered `oklch` gradients, `backdrop-filter` for refractive "liquid glass" effects, GPU-accelerated `transform` animations) to create living, breathing backgrounds.
-  - **Performance Optimization:** Ensure all animations strictly use compositor-thread properties (`transform`, `opacity`) and apply `contain: paint` / `will-change: transform` to prevent layout thrashing/flickering.
-  - **Design Resources (Examples/Inspiration):**
-    - [Uiverse.io Patterns](https://uiverse.io/patterns)
-    - [MagicPattern CSS Backgrounds](https://www.magicpattern.design/tools/css-backgrounds)
-    - [Prismic Blog: CSS Background Effects](https://prismic.io/blog/css-background-effects)
-    - [CSS-Pattern.com](https://css-pattern.com) (Pure CSS pattern library)
-    - [BGJar](https://bgjar.com) (Performance-focused generators)
-  - **Goal:** Treat each theme/background as a week-long development sprint to ensure professional polish, WCAG AA contrast compliance for overlaying UI, and seamless integration with the Lotus TDS.
-
-### 6. Exclusive Background vs. Seasonal Choice
-
-- **File:** `cinny/src/app/state/settings.ts`
-- **Status:** **FIXED ⚠️ UNTESTED** — needs verification: (a) pick a background, confirm seasonal theme auto-clears; (b) pick a seasonal theme, confirm background auto-clears; (c) set both via old localStorage data and reload, confirm SeasonalEffect guard suppresses the overlay
-- **Issue:** Concurrent application of both Chat Backgrounds and Seasonal Themes causes visual clutter and high GPU usage.
-- **Root Cause:** These are currently handled as independent settings in the `settingsAtom` and applied simultaneously without mutual exclusion.
-- **Fix Applied:** Mutual exclusion enforced at two layers: (1) `General.tsx` — ChatBgGrid clears seasonalThemeOverride→'off' when any non-'none' background is picked; SeasonalBgGrid clears chatBackground→'none' when any real seasonal theme is selected. (2) `SeasonalEffect.tsx` — runtime guard returns null if `chatBackground !== 'none'`, protecting against legacy persisted state.
-
-### 7. Tiny Touch Targets in Composer Toolbar
-
-- **File:** `cinny/src/app/features/room/RoomInput.tsx`
-- **Status:** **FIXED ⚠️ UNTESTED** — needs verification on a real mobile device: open composer, confirm all toolbar buttons are tappable without mis-taps
-- **Issue:** Toolbar buttons have hit areas smaller than the WCAG-recommended 44x44px for touch, hindering mobile accessibility.
-- **Fix Applied:** Added `touchTarget = { minWidth: '44px', minHeight: '44px' }` computed from `mobileOrTablet()` and applied as `style={touchTarget}` to all 8 composer toolbar `IconButton` elements (attach, format, sticker, emoji, GIF, location, poll, schedule, send).
-
-### 8. Horizontal Overflow in Room Settings
-
-- **File:** `cinny/src/app/components/page/style.css.ts`
-- **Status:** **FIXED ⚠️ UNTESTED** — needs verification: open Room Settings on a narrow mobile screen, confirm nav panel fills full width and no horizontal scrollbar appears
-- **Issue:** Wide tables and input elements in room settings cause horizontal overflow on mobile viewports.
-- **Fix Applied:** Added `@media (max-width: 750px) { width: '100%' }` to both `'400'` and `'300'` size variants of the `PageNav` vanilla-extract recipe in `style.css.ts`.
-
-### 9. Modal Float-Style Responsiveness
-
-- **File:** Multiple modal files
-- **Status:** **FIXED ⚠️ UNTESTED** — needs verification by opening each modal on a real mobile device
-- **Issue:** Modals appear as floating boxes on mobile, creating navigation and readability challenges.
-- **Fix Applied:** Created `useModalStyle(desktopMaxWidth)` hook (`src/app/hooks/useModalStyle.ts`) that returns fullscreen styles on mobile (no border-radius, no max-width, `height: 100%`) and desktop box styles otherwise. Applied to all 22+ modal files: `LeaveRoomPrompt`, `LeaveSpacePrompt`, `ReportRoomModal`, `ReportUserModal`, `DeviceVerification`, `InviteUserPrompt`, `LogoutDialog`, `DeviceVerificationSetup`, `DeviceVerificationReset`, `JoinAddressPrompt`, `JumpToTime`, `EditHistoryModal`, `ForwardMessageDialog`, `RemindMeDialog`, `CreateRoomModal`, `CreateSpaceModal`, `ScheduleMessageModal`, `PollCreator`, `AddExistingModal`, `RoomEncryption`, `RoomUpgrade`, `Modal500`, `ReadReceiptAvatars`, `RoomTopicViewer`.
-- **Note:** `UIAFlowOverlay` already fullscreen via `<Overlay>` — no change needed. `JoinRulesSwitcher`/`RoomNotificationSwitcher` are dropdowns, not modals.
-
-### 10. Composer Keyboard Obscurity
-
-- **File:** `src/index.css`
-- **Status:** **FIXED ⚠️ UNTESTED** — needs verification on iOS Safari specifically (the worst offender); on Android Chrome `100dvh` has been standard since Chrome 108
-- **Issue:** The chat composer is often partially or fully obscured by the virtual keyboard on mobile.
-- **Fix Applied:** Added `height: 100dvh` (dynamic viewport height) to `html` alongside the existing `height: 100%` fallback. `dvh` updates when the software keyboard appears, ensuring the layout shrinks correctly and the composer stays visible.
-
-### 11. Inline Jotai atom creation
-
-- **File:** `cinny/src/app/hooks/useSpaceHierarchy.ts`
-- **Status:** **FALSE POSITIVE — CLOSED**
-- **Issue:** Inline Jotai atom creation in a hook risks re-rendering components unnecessarily.
-- **Resolution:** `useState(() => atom(...))` IS the correct Jotai pattern for local stable atom references. The factory function form of `useState` ensures the atom is created only once per component mount. No change warranted.

-| State Sync              | Fire-and-forget network call to set offline presence during `pagehide` event may not complete reliably, potentially causing UI drift in presence status. | `cinny/src/app/hooks/usePresenceUpdater.ts`     | FIXED (`d2946c00`) — unload path now uses `fetch({ keepalive: true })` so the request survives page teardown (`sendBeacon` was unusable here: it can't set the auth header).                                                                                                                                          |
-| State Sync              | Fire-and-forget network call `setPresence().catch(...)` suppresses errors, meaning the app may falsely assume presence update success.                   | `cinny/src/app/hooks/usePresenceUpdater.ts`     | FIXED (`d2946c00`) — errors are now surfaced via `warnPresenceFailure` (redacted logging) instead of being silently swallowed.                                                                                                                                                                                        |
-| Memory Leak             | Decrypted Media Memory Leak (Gallery & Lightbox) due to missing virtualization and blob revocation.                                                      | `cinny/src/app/features/room/MediaGallery.tsx`  | PARTIALLY FIXED ⚠️ UNTESTED — Blob revocation was already correct; added `enabled` param to `useDecryptedMediaUrl` and `useNearViewport(300px)` to each `GalleryTile` to gate decryption until near-viewport, reducing burst on pagination. True virtualization (windowing) deferred — requires significant refactor. |
-| Data Persistence        | Scheduled Messages are ephemeral (lost on refresh) due to fragile `localStorage` parsing.                                                                | `cinny/src/app/state/scheduledMessages.ts`      | FIXED — now uses `atomWithStorage` + `createJSONStorage` (Jotai's built-in persistence with error-safe JSON parsing)                                                                                                                                                                                                  |
-| Memory Leak             | Potential memory leak due to uncleaned `handleMouseMove` listener in `usePan`.                                                                           | `cinny/src/app/hooks/usePan.ts`                 | FALSE POSITIVE — `usePan` already uses `attachedRef` to track listeners and cleans them up in an unmount `useEffect`. No change needed.                                                                                                                                                                               |

-| Data Persistence        | Non-atomic `localStorage` updates in session management can lead to inconsistent state.                                                                  | `cinny/src/app/state/sessions.ts`               | OPEN                                                                                                                                                                                                                                                                                                                  |
-| Data Persistence        | Lack of cross-tab synchronization for `localStorage` updates in session management risks race conditions.                                                | `cinny/src/app/state/sessions.ts`               | OPEN                                                                                                                                                                                                                                                                                                                  |
-| Network Resilience      | `uploadContent` lacks retry logic, failing immediately upon network error.                                                                               | `cinny/src/app/utils/matrix.ts`                 | FIXED (`d2946c00`) — bounded retry (`UPLOAD_MAX_RETRY_COUNT=3`) gated by `isRetryableUploadError` (transient/network/5xx/429 only, not 4xx), reusing the `rateLimitedActions` capped-exponential backoff.                                                                                                             |
-| Network Resilience      | `rateLimitedActions` uses basic retry logic without exponential backoff, which may exacerbate 429 issues.                                                | `cinny/src/app/utils/matrix.ts`                 | FIXED — fallback delay now uses capped exponential backoff (`min(1000 * 2^retryCount, 30_000)ms`) when server doesn't send `Retry-After`; server header still takes precedence via `getRetryAfterMs()`.                                                                                                               |
-| Matrix Event Robustness | `useMatrixEventRenderer` handles unknown events gracefully by returning `null`, which may hide potentially important unrendered data.                    | `cinny/src/app/hooks/useMatrixEventRenderer.ts` | FALSE POSITIVE — returning `null` for unrendered types is the intended contract. Callers opt into rendering unknowns via the `renderStateEvent` / `renderEvent` fallback params; `null` only results when the caller deliberately supplies no fallback. No change warranted.                                          |
-| Data Contract           | `MatrixError` instantiation with `UploadResponse` might be brittle.                                                                                      | `cinny/src/app/utils/matrix.ts`                 | FIXED (`d2946c00`) — replaced the brittle direct construction with `matrixErrorFromUploadResponse` / `matrixErrorFromUnknown` guards that validate shape before building a `MatrixError`.                                                                                                                             |
-| Type Safety             | `addRoomIdToMDirect` uses `as any` cast for `AccountDataEvent.Direct`, bypassing type contract validation.                                               | `cinny/src/app/utils/matrix.ts`                 | FIXED (`d2946c00`) — `addRoomIdToMDirect` / `removeRoomIdFromMDirect` now use `EventType.Direct` + a typed `MDirectContent`, dropping the `as any` cast.                                                                                                                                                              |
-| Robustness              | `rateLimitedActions` relies on `MatrixError.httpStatus` which might not exist on all error variants.                                                     | `cinny/src/app/utils/matrix.ts`                 | FALSE POSITIVE — `MatrixError.httpStatus` is defined as `readonly httpStatus?: number` in `matrix-js-sdk/lib/http-api/errors.d.ts`. It is optional (not on all instances) but the `?.` optional chain already guards against undefined. No change needed.                                                             |
-| Type Contract           | Custom types in `cinny/src/types/matrix` mirror SDK types instead of using them, risking drift and contract mismatches.                                  | `cinny/src/types/matrix/`                       | OPEN                                                                                                                                                                                                                                                                                                                  |

-| Hardcoded color `#EE1D52`, `#9146ff`, `#ff4500`, `#cb3837`, `#f48024` ⚠️ **BRAND EXCEPTION** | `cinny/src/app/components/url-preview/UrlPreviewCard.tsx` + `UrlPreview.css.tsx` — official third-party brand colors in SVG logos and site badge backgrounds; cannot convert to CSS variables without inventing new tokens (violates TDS rule 3)                                                                                             |
-| Massive number of hardcoded `backgroundColor` values ⚠️ **PATTERN CONTENT EXCEPTION**        | `cinny/src/app/features/lotus/chatBackground.ts` — each background's base color is aesthetic content that defines the pattern identity; converting requires inventing 40+ CSS variables (violates TDS rule 3) or using CSS4 `relative-color-syntax` in inline styles (insufficient browser support); these are visual content, not UI chrome |

-| Element Call Integration | Lacks robust iframe failure monitoring beyond initial 'preparing' event; can result in a permanently hung 'Loading...' state with no user-visible error or recovery path.                                    | `src/app/plugins/call/CallEmbed.ts`                     | FIXED (`0394fce9`) — added a `CALL_LOAD_WATCHDOG_MS` (25s) timeout that settles on ready/capabilities/joined and fails on iframe error/timeout, exposing a `loadFailed` getter + `onLoadError(cb)`. `CallView` renders a `CallLoadErrorMessage` overlay (Retry/Leave) instead of a permanent spinner. ⚠️ UNTESTED — needs a live call. |
-| Component Resilience     | `RoomTimeline` has no `ErrorBoundary` wrapper — a single malformed event crashing the renderer takes down the entire timeline with no fallback UI.                                                           | `src/app/features/room/RoomTimeline.tsx`                | FALSE POSITIVE — `RoomView.tsx` (lines 113–137) already wraps `<RoomTimeline>` in a react-error-boundary `ErrorBoundary` with a "Timeline unavailable" fallback. A wave-1 agent's redundant nested boundary was reverted. No change needed.                                                                                            |
-| Component Resilience     | `RoomInput` has no `ErrorBoundary` wrapper — a crash in the composer leaves users unable to send messages.                                                                                                   | `src/app/features/room/RoomInput.tsx`                   | FALSE POSITIVE — `RoomView.tsx` (lines 151–171) already wraps `<RoomInput>` in an `ErrorBoundary` with a "Message composer encountered an error" `RoomInputPlaceholder` fallback. No change needed.                                                                                                                                    |
-| Fallback Logic           | No explicit empty/error fallback for Matrix SDK data calls in `RoomTimeline`; relies purely on SDK internal error propagation, meaning silent failures show a blank timeline.                                | `src/app/features/room/RoomTimeline.tsx`                | ADDRESSED — the `RoomView` `ErrorBoundary` (above) provides the explicit render-error fallback; a thrown SDK/render error now surfaces "Timeline unavailable" rather than a blank timeline.                                                                                                                                            |
-| Dependency               | Potential for complex dependency chains due to deep nesting in `src/app/features/` and `src/app/hooks/`.                                                                                                     | `src/app/`                                              | OPEN                                                                                                                                                                                                                                                                                                                                   |
-| Hydration/Race Condition | The SyncState listener registered by useSyncState may miss the initial 'PREPARED' event if the client initializes synchronously from IndexedDB before the effect runs, leading to an infinite loading state. | `cinny/src/app/pages/client/ClientRoot.tsx`             | OPEN                                                                                                                                                                                                                                                                                                                                   |
-| Structure                | High number of small, highly coupled utility hooks (`src/app/hooks/`) may obscure dependency graphs.                                                                                                         | `src/app/hooks/`                                        | OPEN                                                                                                                                                                                                                                                                                                                                   |

-## 🎨 Native UI/UX Consistency — Lotus vs. Cinny Baseline
-
-> Audit of every Lotus-custom UI feature against Cinny's native folds design-system conventions. "Native pattern" means the `folds` component library, vanilla-extract tokens (`color.*`, `config.radii.*`, `config.space.*`), and established Cinny component patterns. 52 findings, organized by severity.

-### 🔴 Major — Broken Styling / Functional Regressions
-
-#### N1. `ProfileDecoration` Save Button — Undefined `--accent-cyan` Variable (border invisible on all non-TDS themes)
-
-- **File:** `src/app/features/settings/account/ProfileDecoration.tsx`, lines 191–213
-- **Status:** **FIXED** — replaced raw `<button>` with `<Button size="400" variant="Success" fill="Solid" radii="300">`, removed undefined `--accent-cyan` reference
-- **Issue:** The save button is a raw `<button>` with `border: '1px solid var(--accent-cyan)'` and `color: 'var(--accent-cyan)'`. The variable `--accent-cyan` (without the `--lt-` prefix) is never defined in any theme file — the correct prefixed form is `--lt-accent-cyan`. On all non-TDS themes the border is **invisible** and the text has no color.
-- **Root Cause:** Missing `--lt-` prefix. Additionally, the raw `<button>` should be a folds `<Button>` to match every other save button in the same `Profile.tsx` settings panel (e.g., `ProfileDisplayName` save at `Profile.tsx:303`).
-- **Fix:** Replace raw `<button>` with `<Button size="400" variant="Success" fill="Solid" radii="300">`. Remove the `--accent-cyan` reference.
-
-#### N2. `UserPrivateNotes` Textarea — Undefined `--border-interactive` Variable (border invisible on all themes)
-
-- **File:** `src/app/components/user-profile/UserRoomProfile.tsx`, lines 246–265
-- **Status:** **FIXED** — replaced undefined CSS vars with `color.SurfaceVariant.ContainerLine`, `config.radii.R300`, `config.space.S200/S300`
-- **Issue:** The notes textarea sets `border: '1px solid var(--border-interactive)'`. This variable is never defined anywhere in the codebase — the correct equivalents are `--bg-surface-border` (`src/index.css`) or `color.SurfaceVariant.ContainerLine` (folds token). The border is **invisible on all themes**.
-- **Root Cause:** Invented CSS variable name. Also uses raw pixel sizing (`borderRadius: '6px'`, `padding: '8px 10px'`, `fontSize: '14px'`) instead of folds tokens.
-- **Fix:** Replace inline style with `border: \`1px solid ${color.SurfaceVariant.ContainerLine}\``, `borderRadius: config.radii.R300`, `padding: config.space.S200`.
-
-#### N3. `LotusToastContainer` — Z-Index Places Toasts Below Night Light Overlay and All Modals
-
-- **File:** `src/app/features/toast/LotusToastContainer.tsx`, lines 184–211; `src/app/pages/App.tsx`
-- **Status:** **FIXED** — raised toast `zIndex` from `9997` to `10001` (above Night Light at 9998 and modals at 9999)
-- **Issue:** The toast container uses hardcoded `zIndex: 9997`. The Night Light overlay is at `z-index: 9998`. The folds `Overlay`/`Dialog` components used for all modals resolve to `z-index: 9999`. Result: (a) toasts render **under** the Night Light tint and take on the warm orange filter; (b) any open modal covers toasts entirely, making notifications invisible.
-- **Root Cause:** The toast container does not use the `folds` `OverlayContainerProvider` portal that manages z-index correctly — it is a plain `position: fixed` div injected directly in `App.tsx`.
-- **Fix:** Either route the toast portal through `OverlayContainerProvider` (matching how all other floating UI works), or raise `zIndex` above all overlay layers (10001+). Also audit Night Light's z-index (9998) relative to toasts.
-
-#### N4. `PollContent` Vote Buttons — Entirely Outside the Folds Design System
-
-- **File:** `src/app/components/message/content/PollContent.tsx`
-- **Status:** **FIXED ⚠️ UNTESTED** (`caf6318a`) — needs verification: create a poll, then view/vote on it under a **non-TDS theme** (e.g. default Cinny dark/light) and confirm borders, selected state, and progress fill are all visible.
-- **Issue:** Each poll answer is a native `<button>` with ~15 hardcoded inline style properties using undefined CSS variables (`--accent-cyan`, `--accent-cyan-dim`, `--accent-cyan-border`, `--border-color`). Checkbox/radio indicators, percentage spans, and the poll label used raw pixel/rem font sizes (`0.68rem`, `0.78rem`, `0.88rem`) and hardcoded `rgba()`/`#fff`. None of those vars exist outside TDS mode — the component rendered unstyled (invisible borders / no selected/progress state) on every non-TDS theme.
-- **Root Cause:** Custom implementation that bypassed folds tokens entirely.
-- **Fix Applied:** Kept the `<button>` structure (the progress-bar-behind-text affordance has no folds `Button` equivalent) but made every value theme-reactive: `color.Primary.*` for selected/indicator state, `color.SurfaceVariant.*` for the resting surface + progress fill, `config.*` for radii/spacing/border-width, and folds `<Text>` for the option label, percentage, and section label (dropping the raw rem sizes and `opacity` hacks). The duplicate checkbox/radio indicator spans were merged into one.

Added Escape-to-close on the panel (previously only the lightbox handled Escape). **Full chrome redesign (round 2)** to match native conventions: panel + header switched from `Surface` to `Background` variant (matching `MembersDrawer`/Saved Messages); header now `Text size="H4"` + plain close `IconButton` (dropped the bespoke tooltip-wrapped button); tabs moved to a bordered toolbar strip with the `variant={active?'Primary':'Secondary'} fill={active?'Solid':'Soft'}` pattern from `PolicyListViewer` and now show per-tab counts; the centered "lines + label" month divider replaced with a left-aligned group label (Cinny group-label pattern); thumbnail tiles moved hover/focus styling to CSS `:hover`/`:focus-visible` (no JS hover state) and into `MediaGallery.css.ts`; file rows + grid tokenized. **Docking fix (round 3)** — the core of the finding: the gallery was a `position: fixed` overlay floating over the timeline, mounted from `RoomViewHeader`. It is now a **docked flex sibling** in the room layout row, exactly like `MembersDrawer`: open state lifted to a `mediaGalleryAtom` (mirrors `bookmarksPanelAtom`), rendered in `Room.tsx` with a vertical `Line` separator on desktop and `key={room.roomId}` to reset per room; the CSS is static-width on desktop and only `position: fixed; inset: 0` full-screen on mobile (identical strategy to `MembersDrawer.css`). It now shares the row with the timeline instead of overlapping it. | `MembersDrawer` uses a vanilla-extract class with `width: toRem(266)` and is placed by the layout system, not `position: fixed`. 54px width discrepancy also breaks visual rhythm if both panels could be open |

-### Round 2 — Additional Feature Areas
-
-#### 🔴 Additional Major Findings
-
-**N53 — PTT Badge (Lotus Terminal path): Raw `<div>` tree with `--lt-*` CSS vars instead of folds `<Chip>`**
-
-- **File:** `src/app/features/call/CallControls.tsx`
-- **Status:** **FIXED** (`50076962`) — removed the `lotusTerminal` branch entirely; the PTT badge is now the single folds `<Chip variant={pttActive ? 'Success' : 'Warning'} fill="Soft" radii="400" outlined>` path for all themes (TDS styling still flows through the CSS-variable layer over the Chip). Dropped the now-unused `lotusTerminal` read. Build-verified; visual parity to confirm only if you specifically used the terminal-mode PTT look.
-- **Issue:** When `lotusTerminal` is true the PTT badge renders as a bare `<Box>` with inline styles referencing `--lt-accent-green-dim`, `--lt-accent-green-border`, `--lt-accent-green` — variables absent outside TDS mode — hardcoded rem padding, `borderRadius: '99px'` (non-token), a raw monospace `fontFamily` string, non-token `letterSpacing`, and a raw `animation:` CSS string for the live-pulse dot. The live `●` dot is a raw `<span>` with inline style.
-- **Root Cause:** Two entirely separate component trees for the same badge depending on a theme boolean. The non-terminal path (lines 284–301) uses the correct `<Chip variant="Success"|"Warning" fill="Soft" radii="400" outlined>`.
-- **Fix:** Remove the terminal branch. The standard `<Chip>` path already exists and TDS theming can be applied via the CSS variable layer without a separate component tree.
-
-**N54 — PiP Mute Overlay Badges: Raw `<div>` instead of folds `<Badge>`/`<Chip>`**
-
-- **File:** `src/app/components/CallEmbedProvider.tsx`, lines 438–477
-- **Status:** **FIXED** — replaced hardcoded `borderRadius`/`padding`/`fontSize` with `config.radii.R300`, `config.space.S100/S200` tokens; replaced raw `<span>` text with folds `<Text size="T200">`; color now applied to the `Icon`/`Text` via `color.Critical/Warning.Main`. The dark translucent scrim (`rgba(0,0,0,0.65)`) is **deliberately retained**: these badges overlay arbitrary video, where a theme `Chip`/`Badge` surface token would not guarantee legibility. They are also non-interactive (`pointerEvents: 'none'`), so an interactive `Chip` (a `<button>`) is semantically wrong.
-- **Issue:** Both the "You muted" (bottom-left) and "All muted" (top-right) PiP badges are raw `<div>` elements with hardcoded `background: 'rgba(0,0,0,0.65)'`, `backdropFilter: 'blur(4px)'`, `borderRadius: '6px'`, `padding: '3px 7px'`, `fontSize: '12px'`. Color is set as `color: color.Critical.Main` directly on the wrapper `<div>`, not via a folds `variant` prop. Text is `<span style={{ fontSize: '11px', fontWeight: 600 }}>`.
-- **Root Cause:** `CallView.tsx` line 127 uses `<Badge variant="Critical" fill="Solid" size="400">` in the same file for the "N Live" indicator — the native pattern exists and is unused here.
-
-**N55 — Chat Background / Seasonal Theme Selected State Uses `color.Critical.Main` (Error Red)**
-
-- **File:** `src/app/features/settings/general/General.tsx`, lines 1660–1661 and 1726–1728
-- **Status:** **FIXED** — replaced all 4 instances of `color.Critical.Main` with `color.Primary.Main` in `General.tsx`
-- **Issue:** The selected-state border for both `ChatBgGrid` and `SeasonalBgGrid` is `border: \`2px solid ${color.Critical.Main}\``and the label color is also`color.Critical.Main`. `color.Critical.Main` is the semantic token for **destructive/error states** — it is used for "Leave Room", "Delete Message", "Report Room" in the same file. A normal selection indicator rendered in error red is semantically wrong and visually alarming.
-- **Root Cause:** Wrong semantic token for an active/selected state.
-- **Fix:** Replace `color.Critical.Main` with `color.Primary.Main` (or `color.Success.Main` to match how other settings selections are styled) for both the border and label color.
-
-**N56 — Report Modal Category Dropdown: Native `<select>` Instead of folds `Chip`+`PopOut`+`Menu`**
-
-- **File:** `src/app/features/room/ReportRoomModal.tsx` lines 138–163; `src/app/features/room/ReportUserModal.tsx` lines 144–169
-- **Status:** **FIXED** — extracted a shared `ReportCategorySelect` component (`src/app/features/room/ReportCategorySelect.tsx`) using the folds `Button` trigger + `PopOut` + `FocusTrap` + `Menu` + `MenuItem` pattern (with `escapeDeactivates`/arrow-key nav, matching `OrderButton`); both modals now use it instead of the native `<select>`.
-- **Issue:** Both report modals render the "Category" field as `<Box as="select">` with hand-rolled inline styles (padding, border, background, color, fontSize, fontFamily). No other selector in the message-action modal context uses `<select>` — the established pattern for all dropdowns in both message modals and search filters is `Chip onClick → setMenuAnchor → PopOut → FocusTrap → Menu → MenuItem` (reference: `OrderButton` in `SearchFilters.tsx` lines 63–114).

-#### 🔴 Additional Major Findings
-
-**N83 — Rich Topic Formatting Toolbar: Raw `<button>` Elements with Fully Inline Styles**
-
-- **File:** `src/app/features/common-settings/general/RoomProfile.tsx`, lines 335–358
-- **Status:** **FIXED** — replaced raw `<button>` elements with `<Button size="300" radii="300" variant="Secondary" fill="Soft">` with styled `<Text>` children for B/I/S/code labels
-- **Issue:** The four formatting buttons (B, I, S, `` ` ``) in the room topic editor are plain HTML `<button>` elements with entirely inline styles: manual `border`, `borderRadius`, `background`, `color`, `cursor`, `fontSize`, `fontWeight`, `fontStyle`, `fontFamily`, `lineHeight`. They bypass the folds design token system completely — no `variant`, `size`, or `radii` props, no theme-reactive hover/focus states.
-- **Root Cause:** Custom addition without referencing folds primitives.
-- **Fix:** Replace with `<IconButton type="button" size="300" radii="300" variant="Surface" fill="Soft">` matching the emoji-picker trigger immediately above them at line 285, which already uses the correct pattern.

-**N84 — Topic Preview in Room Settings Renders Plain Text Instead of `formatted_body`**
-
-- **File:** `src/app/features/common-settings/general/RoomProfile.tsx`, lines 457–461
-- **Status:** **FIXED** — read-mode topic now checks `topic.format === 'org.matrix.custom.html'` and renders `parse(sanitizeCustomHtml(topic.formatted_body))`, matching `RoomTopicViewer` and all other display sites
-- **Issue:** The read-mode topic display wraps `topic.topic` (the plain-text field) in `<Linkify>` and never reads `formatted_body`. However `buildTopicContent()` (lines 82–89) intentionally stores both `topic` and `formatted_body` under `org.matrix.custom.html`. After the user saves a formatted topic, the preview panel immediately shows the stripped plain-text version — the formatting appears to disappear within the same settings panel.
-- **Root Cause:** The existing `RoomTopicViewer` component (`src/app/components/room-topic-viewer/RoomTopicViewer.tsx:24–51`) already checks `topic.format === 'org.matrix.custom.html'` and pipes `formatted_body` through `sanitizeCustomHtml`. This component is used everywhere else (`RoomIntro`, `LobbyHero`, `RoomItem`, `Invites`, etc.) but not in Room Settings.
-- **Fix:** Replace the inline plain-text render with `<RoomTopicViewer topic={roomTopic}>` to match all other display sites.

 ## 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

+
+### 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).

 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`.

+### 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)

+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`).

+**Privacy-friendly facade.** The tile first shows the homeserver's cached
+`og:image` thumbnail + a play button; the third-party `<iframe>` is only mounted

+- Supports 2 to 10 answer options; single-choice or multiple-choice

Defaults to the option count (unchanged "select all that apply" behavior) until you lower it; the display side already enforces the cap ("Select up to N")

-### 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.

+### 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.

+## Threads (P3-8)
+
+Full threaded-conversation support (`m.thread`, matrix-js-sdk `threadSupport`), Element-consistent.
+
+### Thread Panel
+
+A right-side drawer (mirrors the members drawer; fullscreen on mobile) with the thread's root message emphasized at top, an "N replies" divider, the full reply timeline (virtualized, back-paginates via `/relations`, decrypts E2EE threads), reactions/edits/redactions, and its own composer. 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`

+### Forward to Multiple Rooms (P6-3)
+
+The Forward Message dialog is a checkbox multi-select: pick any number of rooms (search + select persist across queries) and **"Send to N rooms"** forwards in one batch (`Promise.allSettled`). Full success auto-closes; a partial failure keeps the dialog open with a "Forwarded to X/N — failed: …" summary. The forwarded content (latest edit via `m.new_content`, reply-quote stripped, undecryptable refused) is built by the shared, unit-tested `forwardContent.ts`.
+
+- **Message preview**: a compact preview at the top of the dialog shows the sender + body (and a thumbnail for image/video) so you can see what you're forwarding.
+- **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`).

 # Lotus Chat — Manual Testing Guide
 
-**Generated:** June 2026
+**Generated:** June 2026 · **Updated:** July 2026 (added §O — threads, per-thread notifications, math, search cache, session hardening, audit wave, desktop CSP; added the **Automated coverage map** below — logic now pinned by unit tests, so manual QA can focus on the human-only surface)
 **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). Screenshots help for anything visual.

+## 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."

+- On a genuine failure/timeout (~25s), instead of an endless spinner you get a **visible error overlay with a single "Back" button** (the old "Retry" + "Leave" pair is gone — they did the same thing and "Retry" was misleading).
+- Clicking **Back** returns you to the call prescreen, where you can manually click Join to try again.
 - Normal joins must **not** trigger the error overlay (no false positives) — this is the important part to confirm.
+- **Self-heal:** if the error overlay appears on a slow network but EC then finishes loading anyway, the overlay should **dismiss itself** and drop you into the live call. Worth confirming on a deliberately throttled-but-not-blocked connection.

+## D2. Element Call **fork** — Phase 2 feature sweep (👥 2 people) — `0.20.1-lotus.1`
+
+> 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.

+## L. Fixed — verify
+
+### L1. AFK auto-mute releases the OS microphone indicator on mute (N95) — 👥 live call
+
+**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 verify:**
+
+1. Enable **AFK auto-mute** in Settings → Calls and **join a call**.
+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.
+
+### L2. Maskable PWA icon (N108) — Android install
+
+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).
+
+---
+
+## M. New features (this round)
+
+### M1. Search: `has:image` / `has:file` / `has:video` filters
+
+1. Open message search (in a room with shared images/files/videos in history).
+2. Run a broad search, then toggle the **Images**, **Files**, **Video** chips (in the filter bar, next to "Has link").
+
+**Expected:**
+
+- Each chip narrows the visible results to that message type; multiple active chips = union (any of them).
+- Toggling them off restores the full results. The existing room/sender/date/has-link filters still work alongside.
+- **Known limitation (by design):** filtering is client-side over already-fetched results, so the visible count can be lower than the server's total for that query — paginating/loading more pulls in more to filter. Confirm this reads acceptably.
+
+### M2. Search: recent searches
+
+1. Run a few different searches, then **clear the search box** and focus it.
+
+**Expected:** your last (up to 10) distinct searches appear as clickable chips; clicking one re-runs it. A **Clear** affordance wipes the list. The list **persists across a page refresh** (localStorage).
+
+### M3. Custom accent color (non-TDS themes) — ⚠️ needs your visual judgment
+
+1. Make sure **Lotus Terminal (TDS)** is **off**. Settings → Appearance → **Custom Accent Color** → pick a color.
+
+**Expected:**
+
+- The app's accent (buttons, selected/active states, links, primary chips) recolors to your choice **live**.
+- **Look critically at quality** (this is the part I can't verify): button **text legibility** (OnMain contrast) on the accent buttons; **hover/active** shades; and **selected-row / chip** backgrounds (the translucent "Container" tints). Try a **light** color and a **dark** color and a **saturated** one.
+  - If a dark accent makes selected-row text (OnContainer) hard to read, tell me — that's the one spot in the auto-derived palette most likely to need tuning.
+- **Reset** clears it back to the theme default.
+- Turn **Lotus Terminal ON** → the custom accent should be **ignored** (TDS fixed palette wins) and the picker shows a "non-TDS only" note; turn it back off → custom accent returns.
+- Reload → the chosen accent **persists**.
+
+---
+
+### M4. Search: "Pinned only" filter
+
+In message search, toggle the **Pinned** chip.
+**Expected:** results narrow to messages currently pinned in their room; composes with the Images/Files/Video chips and room/sender/date filters; toggling off restores results. It also narrows the **encrypted/local-cache** results section (not just server results). Needs a room with actually pinned messages.
+
+### M5. New theme presets (Cyberpunk / Ocean / Blood Red / Classic Matrix / Midnight) — ⚠️ visual judgment
+
+Settings → Appearance → theme picker → try each of the 5 new themes.
+**Expected:** each applies a complete, legible dark palette. Code review computed WCAG contrast and all pass AA, but **eyeball these specifically**: **Midnight** (lowest-contrast accent `#6b7ca8` — selected/focus states), **Classic Matrix** (green accents, light-green body text on near-black), **Blood Red** (white-ish text on bright-red buttons). Confirm Success/Warning/Critical (save/leave/delete) still look correctly green/amber/red, not recolored. Switching back to a stock theme should fully revert.
+
+---
+
+## 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.

+### 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
+(`io.lotus.set_quality`).

+# 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.
