docs: park Sliding Sync (evaluated — not viable for a safe rollout)

Three research passes concluded ~10% confidence a full rollout wouldn't
break/regress (js-sdk SlidingSync is _internal_/experimental + labs-only at
Element, presence not delivered over sliding sync, no upstream Cinny reference,
and Cinny's nav is built from the full local room set — ~14 subsystems assume
completeness). Server side is GA. Parked; revisit on Rust SDK adoption or large
accounts. Full assessment in the plan history.

-# HANDOFF — Forking & Self-Building Element Call ("Lotus Call")
-
-> **Audience:** a fresh Claude/engineer session with **no prior context** on this
-> project. Read this top-to-bottom before touching anything. This document is the
-> single source of truth for the Element Call (EC) fork initiative.
->
-> **Status:** **PHASE 0–2 IMPLEMENTED (build-verified, not yet live-tested)**
-> (2026-06-30). The fork exists, builds, is published, and cinny consumes it
-> (Phase 0/1). **All 7 Phase-2 EC features are implemented on the fork's `lotus`
-> branch**, each additive + flag-gated, build+typecheck-clean, per-feature
-> reviewed (+ a holistic multi-agent review), and pushed. **None are live-tested
-> yet** — every one needs the `LOTUS_TESTING.md` §D sweep, and the **cinny host
-> side must be wired** (set flags / send actions / handle call_state) — see §12.
-> See **§9** Phase 0/1 results, **§10** cutover, **§11** Phase-2 seams, **§12**
-> Phase-2 status + cinny integration checklist. Created 2026-06 from `LotusGuild/cinny`.

-## 9. Phase 0 Results (verified 2026-06-29)
-
-**Decisions taken with the user:** scope = Phase 0 recon; consumption model =
-**private npm package** (§5 option 1). Recommended registry = **Gitea's built-in
-npm registry** (`code.lotusguild.org`) — zero new infra.
-
-### 9.1 Version → tag → commit mapping (LOCKED)
-
-| Source                                               | Value                                      |
-| :--------------------------------------------------- | :----------------------------------------- |
-| cinny `package.json` pin                             | `@element-hq/element-call-embedded@0.20.1` |
-| Bundle self-report (`VITE_APP_VERSION`/`appVersion`) | `embedded-v0.20.1`                         |
-| npm registry `gitHead` for 0.20.1                    | `2d74c48151d9edc01c65a22a91478aac81bf24d0` |
-| GitHub tag `v0.20.1` → commit                        | `2d74c48…` ✅ **same commit**              |
-
-→ **Fork from upstream tag `v0.20.1` (commit `2d74c48`).** The embedded package
-version equals the element-call release tag; repo `package.json` version is
-`0.0.0` and the real version is stamped at publish time from the tag.
-
-### 9.2 The shipped npm dist is a CLEAN upstream build
-
-No `lotus`/`denoise`/`rnnoise` strings anywhere in
-`node_modules/@element-hq/element-call-embedded/dist`. **All Lotus customization
-(denoise shim) is injected at cinny build time, not baked into the package** — so
-swapping the source does not disturb cinny's denoise injection layer. The
-ringtone/reaction assets (`baduntss`, `cat`, `clap`, `call_declined`, …) are
-upstream EC's own, not ours.
-
-### 9.3 Build toolchain & mechanism
-
-- **Node `24`** (`.node-version`), **pnpm `10.33.0`** (`packageManager` field,
-  via corepack).
-- Build: **`pnpm run build:embedded`** = `vite build --config
-vite-embedded.config.ts` with `NODE_OPTIONS=--max-old-space-size=16384`.
-- Output dir is **repo-root `dist/`**; CI stages it into **`embedded/web/dist`**
-  (the `embedded/web/` dir holds the publish template: `package.json`, README,
-  both LICENSE files).
-- Publish workflow upstream = `.github/workflows/publish-embedded-packages.yaml`:
-  builds → `npm version <tag> --no-git-tag-version` → `npm publish --provenance
---access public` to npmjs as `@element-hq/element-call-embedded`. (Also
-  Android/Maven + iOS/SwiftPM — irrelevant; we are web-only.)
-
-### 9.4 Build reproduction — PARITY CONFIRMED
-
-Cloned `element-call@v0.20.1` to `/root/code/element-call` (shallow), built with
-isolated Node 24 / pnpm 10.33.0 (system Node 20 / cinny untouched). Result vs the
-shipped npm dist:
-
-- **137 of 147 files byte-identical** (same Vite content-hash): all CSS, fonts,
-  wasm, audio, JSON locale files, and `IndexedDBWorker`.
-- **Only 5 JS chunks differ** (`index`, `pako.esm`, `polyfill-force`,
-  `rust-crypto`, `spa`) — **cause isolated to the version define**: our local
-  build baked `appVersion:\`dev\``(because`VITE_APP_VERSION`was unset) vs the
-npm build's`appVersion:\`embedded-v0.20.1\``. `index.html` is identical modulo
-  the hashed asset filenames. **Benign** — our CI sets the version from the git
-  tag, so a tagged CI build will match.
-
-### 9.5 Fork CI (drafted)
-
-`.gitea/workflows/ci.yml` is staged in the clone (models cinny's
-`.gitea/workflows/ci.yml` + upstream's publish flow). Linux-only (`ubuntu-latest`)
-— the Windows worker is for cinny-desktop/Tauri, not the EC web bundle. Build job
-on PR/push to `lotus`; publish job on `v*` tag → `@lotusguild/element-call-embedded`
-to the Gitea npm registry (needs `secrets.GITEA_NPM_TOKEN`).
-
-### 9.6 Phase 1 — DONE (2026-06-29)
-
-1. ✅ **Fork repo live:** `code.lotusguild.org/LotusGuild/element-call` (public,
-   AGPL), default branch `lotus`, full history (7018 commits) + tag `v0.20.1`.
-   Branch `lotus` = `v0.20.1` + 2-file diff (CI workflow + embedded package
-   rename).
-2. ✅ **Package published:** `@lotusguild/element-call-embedded@0.20.1` on the
-   Gitea npm registry (published manually from the version-faithful build while
-   the admin token was available). **Publicly readable** (unauth `npm install`
-   works → devs/CI need no token to consume; only publishing needs one).
-3. ✅ **cinny wired & built clean** (Node 24): `.npmrc` scope line +
-   `package.json` dep + `vite.config.js` `viteStaticCopy` src. `npm install`
-   swapped the package (resolved from Gitea), `npm run build` succeeded,
-   `dist/public/element-call/` populated, bundle reports `appVersion:
-embedded-v0.20.1`, **denoise shim injected + all denoise assets copied**
-   (injection layer unchanged). **These cinny edits are staged in the working
-   tree, NOT committed/pushed** — pushing triggers CI → desktop → deploy, so it's
-   gated on the §D live test (see §10).
-
-### 9.8 Reproducibility note (important)
-
-A from-source rebuild is **NOT byte-identical** to upstream's npm tarball.
-137/147 files match exactly (CSS, fonts, wasm, audio, worker); the 5 JS chunks
-(`index`, `pako.esm`, `polyfill-force`, `rust-crypto`, `spa`) differ because the
-rolldown/oxc **minifier mangles export names differently** across build
-environments (and the version-define is one input). This is normal and benign —
-the code is functionally equivalent. **Do not chase byte-parity; the §D live call
-test is the real parity gate.**
-
-### 9.9 Remaining follow-ups (not blocking the cutover)
-
-- **CI publishing:** `.gitea/workflows/ci.yml` publishes on a `v*` tag but needs
-  (a) a Gitea Actions runner for `LotusGuild/element-call`, and (b) a **durable**
-  `GITEA_NPM_TOKEN` repo secret with package read/write (the admin token used for
-  the manual publish is being deleted, so it was deliberately NOT baked in). Until
-  then, publishing is manual (`npm version <tag>` in `embedded/web` →
-  `npm publish`).
-- Decide rebase cadence vs upstream (0.20.2 / 0.20.3 already out — see §9.1).
-
-### 9.7 Ready-to-apply artifacts (staged 2026-06-29)
-
-**Fork side — already committed** on branch `lotus` in `/root/code/element-call`
-(remote `lotus` = `code.lotusguild.org/LotusGuild/element-call.git`, push deferred
-until the repo exists). Minimal 2-file diff vs tag `v0.20.1`:
-`.gitea/workflows/ci.yml` (new) + `embedded/web/package.json` (rename to
-`@lotusguild/element-call-embedded`). Push with:
-`git push -u lotus lotus && git push lotus v0.20.1` (and tag `v0.20.1` on our side
-to trigger the first publish, or push our own `v0.20.1` tag).
-
-**cinny side — NOT yet applied** (applying before the package is published breaks
-`npm ci`). Exactly 3 edits + a lockfile regen:
-
-1. `.npmrc` — append the scoped-registry line:
-   ```
-   @lotusguild:registry=https://code.lotusguild.org/api/packages/LotusGuild/npm/
-   ```
-   (CI/auth: `//code.lotusguild.org/api/packages/LotusGuild/npm/:_authToken=${GITEA_NPM_TOKEN}`
-   — inject via env in CI, do not commit a plaintext token.)
-2. `package.json:104` —
-   `"@element-hq/element-call-embedded": "0.20.1"` →
-   `"@lotusguild/element-call-embedded": "0.20.1"`.
-3. `vite.config.js:25` — `viteStaticCopy` src:
-   `node_modules/@element-hq/element-call-embedded/dist` →
-   `node_modules/@lotusguild/element-call-embedded/dist`.
-   **`stripBase: 4` stays unchanged** — `node_modules/@lotusguild/element-call-embedded/dist`
-   is still exactly 4 leading segments. (Update the comment's path reference too.)
-4. `package-lock.json` — regenerated by `npm install`, not hand-edited (drops the
-   `registry.npmjs.org/@element-hq/...` resolved URL for the Gitea one).
-
-The denoise injection (`lotusDenoise()` in `vite.config.js`) is **unchanged** — it
-keys off `dist/public/element-call/index.html`, which our fork's bundle still
-produces identically (verified: `index.html` byte-identical modulo asset hashes).
-
----
-
-## 0. TL;DR / The Goal
-
-We embed **Element Call** (the Matrix group-VoIP/video app) inside Lotus Chat to
-power voice/video channels. Today we consume Element's **pre-compiled npm
-bundle** and can only steer it from the outside (a limited widget API + fragile
-same-origin DOM hacks). Several in-call problems are **unfixable from outside**
-because they live in EC's compiled JS.
-
-**We want true ownership: fork `element-hq/element-call`, build it from source
-ourselves, host our build, and replace the npm bundle with our fork.** Then
-every in-call behavior becomes editable code.
-
-**This requires standing up a brand-new repo and build pipeline for our EC fork.**
-

-| **A5** — focus camera / fullscreen during screenshare  | Can't reliably spotlight a participant's camera while someone screenshares | EC's **layout logic** (screenshare priority, spotlight) is compiled JS we don't control. We currently DOM-click tiles as a hack.                            |

-
-**Bottom line:** the iframe is **same-origin** (we self-host it), so we can read
-and even write its DOM — but we **do not own its source**, so we can't change its
-**behavior/logic**, only poke at its rendered output. Forking removes that wall.
-
----
-
-## 2. How EC is integrated TODAY (the current architecture)
-
-Understand this fully before changing it — the fork must slot into the same
-integration seams.
-
-### 2.1 Where the EC bundle comes from
-
-- npm package: **`@element-hq/element-call-embedded`**, pinned to **`0.20.1`** in
-  `cinny/package.json` (line ~104).
-- It ships a **pre-built `dist/`**. At cinny build time,
-  `vite-plugin-static-copy` copies that `dist/` flat into
-  **`public/element-call/`** (see `cinny/vite.config.js`, the `copyFiles`
-  target with `rename: { stripBase: 4 }` — note the stripBase gotcha documented
-  there; getting this wrong 404s the widget).
-- It is **NOT committed** to git (`git ls-files public/element-call` → 0). It's a
-  build artifact materialized from `node_modules`.
-
-### 2.2 How EC is loaded & controlled
-
-- The widget iframe `src` is **same-origin**:
-  `${BASE_URL}/public/element-call/index.html?<params>` (see
-  `cinny/src/app/plugins/call/CallEmbed.ts`, `getWidget()` /
-  `getIframe()`). Sandbox: `allow-forms allow-scripts allow-same-origin
-allow-popups allow-modals allow-downloads`; `allow="microphone; camera;
-display-capture; autoplay; clipboard-write;"`.
-- **Control surface #1 — the official widget API** (`matrix-widget-api`):
-  `ClientWidgetApi` + a custom `CallWidgetDriver`. This is the robust,
-  version-stable channel (theme change, hangup, capabilities, timeline events).
-  Files: `plugins/call/CallEmbed.ts`, `plugins/call/CallWidgetDriver.ts`,
-  `plugins/call/utils.ts` (capabilities), `plugins/call/CallControl.ts`.
-- **Control surface #2 — same-origin DOM poking** (fragile, version-coupled):
-  reading `iframe.contentDocument` to detect speakers/mute state and
-  `.click()`-ing tiles to focus a camera. Files:
-  `hooks/useCallSpeakers.ts` (reads `[data-muted]`, `[data-video-fit]`),
-  `plugins/call/CallControl.ts` (`focusCameraParticipant` — tile selectors).
-  **These selectors break on every EC version bump.** A fork lets us replace
-  these hacks with real APIs/props.
-- **Control surface #3 — URL params + build-time injection** for our denoise
-  shim (see §6).
-
-### 2.3 Full file inventory (everything that touches EC in cinny)
-
-Plugin / core:
-
-- `src/app/plugins/call/CallEmbed.ts` — iframe creation, widget API wiring, theme sync, hangup, load watchdog/self-heal, denoise URL params.
-- `src/app/plugins/call/CallControl.ts` — control state + **DOM-poking** (`focusCameraParticipant`, spotlight).
-- `src/app/plugins/call/CallControl.tsx` _(call-status variant)_ and `features/call-status/CallControl.tsx`.
-- `src/app/plugins/call/CallWidgetDriver.ts` — widget driver (capabilities, event relay).
-- `src/app/plugins/call/utils.ts` — widget capabilities set.
-- `src/app/plugins/call/hooks.ts`, `index.ts` — plugin exports/hooks.
-- `src/app/state/callEmbed.ts` — jotai atoms for the active embed.
-
-React / UI:
-
-- `src/app/components/CallEmbedProvider.tsx` — the big one: incoming-call ring/banner, RTCNotification + **RTCDecline** listeners, PiP, mute badges, fullscreen, ringtones.
-- `src/app/features/call/CallView.tsx` — prescreen lobby vs joined (the iframe placement target), load-error recovery UI.
-- `src/app/features/call/CallControls.tsx` — in-call control bar (mic/cam/deafen/screenshare/fullscreen/more/PiP).
-- `src/app/features/call/CallMemberCard.tsx` — **lobby** participant roster (this is where `AvatarDecoration` works today; in-call grid is EC's).
-- `src/app/features/call/PrescreenControls.tsx` — join controls.
-- `src/app/features/call-status/*` — `CallStatus.tsx`, `MemberGlance.tsx` (the "Focus camera" menu lives here), `LiveChip.tsx`.
-- `src/app/features/room-nav/RoomNavItem.tsx`, `features/room/Room.tsx`, `features/room/RoomViewHeader.tsx`, `pages/client/space/Space.tsx`, `pages/CallStatusRenderer.tsx`, `pages/Router.tsx` — call entry points / status surfacing.
-
-Hooks:
-
-- `src/app/hooks/useCallEmbed.ts`, `useCall.ts`, `useCallSpeakers.ts` (DOM-poking), `useCallJoinLeaveSounds.ts`, `useAfkAutoMute.ts`.
-
-Build:
-
-- `cinny/vite.config.js` — `copyFiles` (EC dist copy) + `lotusDenoise()` plugin (denoise asset copy + index.html shim injection, in `closeBundle`).
-
-Utils:
-
-- `src/app/utils/ringtones.ts`, `utils/denoisePipeline.ts`, `utils/lotusDenoiseUtils.ts`.
-

-
-## 3. Hosting / infra context (the OTHER repo)
-
-There are **two repos**:
-
-1. **`LotusGuild/cinny`** (`/root/code/cinny`) — this Lotus Chat fork. Consumes EC.
-2. **`LotusGuild/matrix`** (`/root/code/matrix`) — the **infra/homeserver** repo.
-   Subdirs: `livekit/` (the SFU EC talks to), `deploy/`, `draupnir/`,
-   `hookshot/`, `landing/`, `matrixbot/`, `systemd/`. Gitea remote
-   `code.lotusguild.org/LotusGuild/matrix`, branch `main`.
-
-EC needs a **LiveKit SFU** + the **livekit-jwt-service**; those live in
-`matrix/livekit/`. A self-hosted EC build must be configured to point at our
-homeserver (`matrix.lotusguild.org` / synapse) and our LiveKit. EC's runtime
-`config.json` (homeserver, livekit URL, feature flags) is part of what we'll own
-once we build it ourselves.
-
-Deployment today: `chat.lotusguild.org` (the cinny web build, which embeds EC at
-`/public/element-call/`). cinny-desktop (`LotusGuild/cinny-desktop`, a Tauri
-wrapper, bumped by cinny CI) embeds the same.
-
----
-
-## 4. The plan (proposed — confirm with the user before executing)
-
-### Decision: **YES, create a new repo.** `LotusGuild/element-call`
-
-Rationale: EC is a large standalone app (React + LiveKit client SDK + matrixRTC +
-its own Vite build + heavy deps). Keep it out of cinny so cinny's build stays
-clean — cinny keeps consuming a **built EC `dist/`**, exactly as today, just
-sourced from **our fork** instead of npm.
-
-### Phase 0 — Recon (no code)
-
-- Fork `github.com/element-hq/element-call` → `LotusGuild/element-call` on Gitea.
-- Pin to the upstream tag matching **0.20.1** (`element-call-embedded` 0.20.1's
-  corresponding `element-call` release) so behavior matches what's shipping now.
-  Verify the embedded-package version ↔ element-call repo tag mapping.
-- Read EC's own build docs: it builds the "embedded" widget bundle (the thing
-  currently published as `@element-hq/element-call-embedded`). Reproduce that
-  build locally and confirm the output matches `public/element-call/` today.
-- **License:** element-call is **AGPL-3.0**, same as Lotus Chat — compatible.
-  Our fork must remain AGPL and publish source.
-
-### Phase 1 — Reproduce current behavior from our fork (parity, no features)
-
-- Build our fork's embedded bundle; wire cinny to consume it instead of the npm
-  package (see §5 for the consumption options). Smoke-test: a call works exactly
-  as today (web + desktop), denoise shim still injects, widget API + theme still
-  work. **No behavior change yet** — this de-risks the swap.
-
-### Phase 2 — Replace the outside hacks with source-level features
-
-Tackle the §1 issues in EC's source:
-
-- **A6:** render avatar decorations as part of the video-tile component
-  (read decoration data we pass in via widget data / URL param / a small bridge).
-- **A5:** fix focus/spotlight + screenshare-coexistence in EC's layout code;
-  expose a clean widget action so cinny can trigger it (kill the DOM `.click()`).
-- **A7:** fix mic re-publish on reconnect; reconcile with our denoise shim (§6) —
-  ideally move denoise INTO the fork as a real audio-processing step instead of a
-  `getUserMedia` monkeypatch.
-- Native Lotus theming/branding at the source (kill the injected-CSS hacks).
-- Then retire the DOM-poking in `useCallSpeakers.ts` / `CallControl.ts` in favor
-  of real widget messages.
-
-### Phase 3 — Maintenance posture
-
-- Decide rebase cadence vs. upstream element-call releases. Keep customizations
-  isolated (feature flags / minimal-diff patches) to ease rebasing.
-- CI in the new repo builds + publishes the embedded dist as a versioned
-  artifact; cinny CI consumes a pinned version.
-
----
-
-## 5. How cinny should consume the fork (pick one — decide with user)
-
-1. **Private npm package** (mirror the current model): our fork's CI publishes
-   `@lotusguild/element-call-embedded` to a registry; cinny depends on it and
-   `viteStaticCopy` keeps working almost unchanged. _Cleanest swap; needs a
-   registry._
-2. **Git submodule + build in cinny CI:** add the fork as a submodule, build it
-   during cinny's build, copy its `dist/` to `public/element-call/`. _No
-   registry; heavier cinny CI._
-3. **CI artifact copy:** fork CI uploads a `dist` tarball; cinny CI downloads a
-   pinned version at build. _Decoupled; needs artifact plumbing._
-
-**Recommendation: Option 1** — it changes the least in cinny (just swap the
-package name in `package.json` + the `viteStaticCopy` src path) and preserves the
-clean cinny/EC separation.
-
----
-
-## 6. The denoise shim — critical interaction (don't break this)
-
-Lotus ships ML noise suppression by **injecting a same-origin pre-init shim into
-EC's `index.html` at build time** (cinny `vite.config.js` → `lotusDenoise()`,
-`closeBundle`). The shim monkeypatches `getUserMedia` **before EC captures the
-mic** and routes audio through RNNoise/Speex/DTLN AudioWorklets, then EC/LiveKit
-publishes the processed track. It's activated via URL params
-(`lotusDenoise=ml&lotusModel=…&lotusGate=…`) set in `CallEmbed.ts`.
-
-- Assets copied to `public/element-call/denoise/` at build (sapphi RNNoise/Speex/
-  gate worklets + `@workadventure/noise-suppression` DTLN tree).
-- Related: `utils/denoisePipeline.ts`, `utils/lotusDenoiseUtils.ts`,
-  `settings/general/DenoiseTester.tsx`, `VoiceMessageRecorder.tsx`.
-- **Known issues:** denoise quality is still poor (tracked separately); and the
-  mic-after-reconnect bug (A7) is suspected to involve the shim's getUserMedia
-  patch handing back a stale processed stream when EC re-acquires the mic.
-
-**Once we own the fork, the right move is to make denoise a first-class
-audio-processing stage inside EC** (not an index.html monkeypatch) — more robust,
-survives reconnects, and removes the build-time injection hack. Until then, the
-fork's `index.html` must remain injectable the same way, or the shim must be
-re-homed into the fork.

-- `LOTUS_TODO.md` (~line 533) calls EC a **"cross-origin iframe"** — **outdated.**
-  EC is **same-origin** today (self-hosted under our domain;
-  `iframe.sandbox` includes `allow-same-origin`; we read `contentDocument`), and
-  **as of 2026-06-29 we own the fork's source** (`@lotusguild/element-call-embedded`).
-  The _practical_ point it made still holds _until we ship the audio-inject API_:
-  **LiveKit's `LocalAudioTrack` lives in EC's module scope**, not on `window`, so
-  cinny can't reach it even same-origin — which is why the in-call soundboard had
-  to be local-playback-only. **The fork removes this wall:** EC can expose a real
-  `io.lotus.inject_audio` widget action (Phase 2) that mixes into the published
-  track from inside its own module scope.
-- `LOTUS_FEATURES.md` documents the EC upgrade history (0.16.3 → 0.19.4 →
-  0.20.1), the dark-mode CSS injection, and AFK auto-mute — all relevant prior
-  art for what the fork must preserve.
-- `LOTUS_TESTING.md` §D is the **EC regression sweep** to re-run after the fork
-  swap (Phase 1 parity check).

-## 8. First actions for the new session
-
-1. Read this file, then skim §2.3's files in `cinny` to internalize the seams.
-2. Confirm with the user: new repo name, consumption model (§5), rebase cadence.
-3. Phase 0: fork element-call, map 0.20.1 ↔ element-call tag, reproduce the
-   embedded build locally, diff against `public/element-call/`.
-4. Phase 1: wire cinny to the fork, run `LOTUS_TESTING.md` §D parity sweep.
-5. Only then start Phase 2 features (A5/A6/A7, theming, denoise-in-source).
-
-**Cross-references:** `LOTUS_BUGS.md` (EC limitations + verify queue),
-`LOTUS_TODO.md` (denoise/soundboard constraints), `LOTUS_FEATURES.md` (EC history),
-`LOTUS_TESTING.md` §D (regression sweep). Infra: `/root/code/matrix` (`livekit/`,
-`deploy/`).
-
----
-
-## 10. Live cutover — the remaining steps (Phase 1 finish)
-
-The fork is published and cinny builds against it locally (§9.6). What's left to
-go live:
-
-1. **Run `LOTUS_TESTING.md` §D** against a local cinny build (`npm run build` is
-   already proven; serve `dist/` or `npm run dev`). Verify a real call: join,
-   mic/cam, screenshare, theme sync, denoise on, widget hangup — web first.
-2. **Commit the cinny edits** (currently staged, uncommitted in the working tree):
-   `.npmrc`, `package.json`, `package-lock.json`, `vite.config.js`. Suggested
-   message: `chore(call): consume self-built @lotusguild/element-call-embedded`.
-3. **Push to `lotus`** → cinny CI builds, then `trigger-desktop` bumps
-   cinny-desktop → Tauri release. Re-run §D on **cinny-desktop** (the path where
-   the old `stripBase` bug bit — verify the widget loads, not a 404).
-4. Only then start **Phase 2** (A5/A6/A7, theming, denoise-in-source).

-## 11. Phase 2 — implementation seams (mapped 2026-06-29)
-
-The exact integration points for each Phase 2 item, found by reading the EC fork
-
-- cinny source. **All of these are media-path / in-call features that cannot be
-  functionally verified without a live Matrix + LiveKit call** — implement each as
-  a minimal, **feature-flagged, additive** diff (no behavior change unless cinny
-  opts in), build-verify the fork (`pnpm build:embedded`, ~15s) AND cinny
-  (`npm run build`), then gate shipping on `LOTUS_TESTING.md` §D.
-
-**Shared widget channel (the backbone for #2/#3/#4/#7):**
-
-- EC→cinny: `widget.api.transport.send("io.lotus.<x>", data)` (see
-  `element-call/src/widget.ts`).
-- cinny→EC actions: add the action name to the `lazyActions` allow-list in
-  `widget.ts` (the array at ~L101) and handle it in EC; cinny sends via
-  `this.call.transport.send(...)`.
-- cinny receives EC→cinny actions via the existing `listenAction(type, cb)`
-  helper in `plugins/call/CallEmbed.ts:626` (auto-replies `{}` so the transport
-  doesn't time out — same pattern as `io.element.device_mute`).
-
-**#2 mute/speaker events** — Source: subscribe to `vm.userMedia$`
-(`CallViewModel`), per member `speaking$` + `audioEnabled$`
-(`state/media/UserMediaViewModel.ts:47-48`); aggregate and
-`transport.send("io.lotus.call_state", {participants:[{id,speaking,audioEnabled}]})`.
-Mount in `room/InCallView.tsx` via `useEffect` guarded by `widget !== null`.
-cinny: `listenAction("io.lotus.call_state")` in `CallEmbed.ts`, feed
-`hooks/useCallSpeakers.ts` → delete its `contentDocument` `[data-muted]` /
-`[data-video-fit]` scrape. _Additive, low risk._
-
-**#4 spotlight/focus** — EC: add `io.lotus.focus_participant` to the `lazyActions`
-list (`widget.ts`), drive `vm`'s spotlight (`spotlightSpeaker$` /
-`spotlight$` in `CallViewModel.ts:898/1001`) to pin a given identity, coexisting
-with `hasRemoteScreenShares$` (L1008). cinny: replace
-`CallControl.ts` `focusCameraParticipant` `.click()` walk with
-`transport.send("io.lotus.focus_participant", {userId})`. _Additive, low risk._
-
-**#3 audio-inject** — EC: add `io.lotus.inject_audio` action; mix an
-`AudioBufferSourceNode` into the published mic track. The local publish path is
-`state/CallViewModel/localMember/Publisher.ts` + `LocalMember.ts` (LiveKit
-`localParticipant`); create a `MediaStreamAudioDestinationNode`, mix mic + clip,
-`replaceTrack`. cinny soundboard calls the action instead of local-only playback.
-_Medium; touches publish path → live-test carefully._
-
-**#1 denoise-in-source** — replace the cinny `lotusDenoise()` `getUserMedia`
-monkeypatch with a real processing stage in EC's mic capture
-(`Publisher.ts`/`LocalMember.ts`; note EC has a `TrackProcessorContext` +
-`BlurBackgroundTransformer` precedent in `livekit/`). EC re-runs it on every
-(re)publish → fixes A7. Remove `vite.config.js` `lotusDenoise()` + URL params in
-`CallEmbed.ts`; move `denoise/` assets into the fork. _Highest value, highest
-risk — most live testing._
-
-**#5 theming** — add a Lotus/TDS theme in EC's theme system (`src/useTheme.ts` +
-EC theme tokens / CSS); driven by the existing `setTheme()` channel cinny already
-calls (`CallEmbed.ts:277`). Bake transparent background. Delete cinny's
-`applyStyles()` injection + `background:none !important`. _Medium._
-
-**#6 in-call decorations** — render the decoration APNG in EC's tile component
-(`tile/GridTile.tsx`); pass slugs via widget member data. cinny already has the
-decoration data + `AvatarDecoration` (lobby `CallMemberCard.tsx`). _Medium-Large._
-
-**#7 quality controls** — set audio `maxBitrate` via
-`RTCRtpSender.setParameters` and screenshare `getDisplayMedia` constraints in
-EC's publish path (`Publisher.ts`); configurable via `config.json` / a widget
-message. Keep the server `voice-limit-guard` as enforcement. _Medium._
-
-**Rollback:** revert the 4 cinny files (restores `@element-hq/...@0.20.1` from
-npmjs). The fork repo/package can stay; nothing else depends on it until pushed.
-
-### Local repro/build environment (this session, 2026-06-29)
-
-- Upstream cloned + our `lotus` branch at `/root/code/element-call` (remote
-  `lotus` → Gitea; origin → github upstream, now un-shallowed/full history).
-- Isolated **Node 24.18.0** lives in the session scratchpad (system Node is 20);
-  cinny's `.node-version` is `24.13.1`, so use Node 24 to build cinny too.
-- Build the embedded bundle: in `/root/code/element-call`, with Node 24 + pnpm
-  10.33.0 on PATH, `VITE_APP_VERSION=embedded-v0.20.1 pnpm run build:embedded`
-  → output in `dist/`; stage to `embedded/web/dist` before publishing.

-## 12. Phase 2 — IMPLEMENTED on the fork (2026-06-30)
-
-All 7 EC features are on the `lotus` branch of `LotusGuild/element-call`, each
-**additive + feature-flagged** (a vanilla call with no `lotus*` params / no Lotus
-actions behaves exactly like upstream), build + `tsc` clean, per-feature reviewed
-(fixes applied) and holistically reviewed. **Not yet live-tested** — all need the
-`LOTUS_TESTING.md` §D sweep.
-
-Fork modules live under `element-call/src/lotus/*`; mounts are `useEffect`s in
-`src/room/InCallView.tsx`. Custom widget actions are in `src/lotus/lotusActions.ts`
-(toWidget ones allow-listed in `src/widget.ts`).

-
-**Security hardening applied** (holistic audit): `lotusDenoiseBase` forced
-same-origin before `audioWorklet.addModule` (was an arbitrary-code-load vector
-via a crafted link); audio-inject gated behind `lotusAudioInject=1`; decoration
-roster capped. Only `https`/`blob` URLs accepted for inject/decoration assets.
-
-### 12.1 cinny host integration checklist (REQUIRED to light these up)
-
-> ✅ **STATUS (2026-06): COMPLETE.** All items below are shipped. call_state,
-> focus_participant, decorations, and transparent background are active; the
-> in-source denoise cutover is done (flag `lotusDenoiseSource=1`, **all four**
-> models in-source); and the two formerly-dormant capabilities now have cinny
-> UI — **soundboard** (`io.lotus.inject_audio`, P5-15) and **quality controls +
-> room permissions** (`io.lotus.set_quality` + `io.lotus.room_quality`, P5-31,
-> with server-side enforcement in `LotusGuild/matrix`). See `LOTUS_FEATURES.md`
-> → "Element Call — Self-Built Fork". The checklist is kept below as the record
-> of what was wired. (One open denoise item tracked separately: the "Series
-> Suppression" native-NS toggle is not wired to the real call path.)
-
-The EC side is additive and dormant until cinny opts in. Host work (in
-`src/app/plugins/call/CallEmbed.ts` unless noted) — **done**:
-
-> ⚠️ **CRITICAL TIMING (protocol audit F1):** only send `io.lotus.*` **toWidget**
-> actions (#3 focus, #6 decorations, #7 quality, audio-inject) **after** the call
-> is joined (`CallEmbed.onCallJoined` / `this.joined`). Those actions are
-> allow-listed at EC app-init (so `preventDefault` suppresses the auto-error)
-> but their handlers only mount with `InCallView` (post-join). Sending earlier
-> leaves the host's `transport.send` pending until the **10s timeout**. Queue and
-> flush on join, or no-op before join.
->
-> Also: **F3 (RESOLVED)** — all four models (`rnnoise`/`speex`/`dtln`/
-> `deepfilternet`) are now implemented in-source in `lotusDenoiseProcessor.ts`;
-> the picker offers all four. **F4** — cinny no longer forwards a native-NS flag
-> in the `ml` branch (the "Series Suppression" toggle is currently a no-op in
-> real calls — open item). **F7** — no widget _capability_ changes needed;
-> custom actions bypass capability checks.
-
-1. **Set the URL flags** on the widget iframe params (the `URLSearchParams` in
-   `CallEmbed`): `lotusCallState=1`, `lotusTransparent=1`/`lotusTheme=1`,
-   `lotusAudioInject=1` as desired. (Denoise sets `lotusDenoiseSource=1` + `lotusModel`/`lotusGate`/`lotusGateThreshold` in the `ml` tier.)
-2. **Ack `io.lotus.call_state`**: add `listenAction('io.lotus.call_state', …)` —
-   without a reply the fork's sends time out every 250ms. Feed the payload into
-   `useCallSpeakers` and RETIRE its `contentDocument` DOM scrape.
-3. **Send actions** via `this.call.transport.send(...)`:
-   `io.lotus.focus_participant` (replace `CallControl.focusCameraParticipant`’s
-   `.click()`), `io.lotus.inject_audio` (from the soundboard), `io.lotus.set_quality`
-   (from quality settings), `io.lotus.decorations` (push the MSC4133 decoration
-   map; resolve mxc→https first).
-4. **#1 denoise cutover**: once verified, STOP injecting the `lotusDenoise()`
-   shim in `cinny/vite.config.js` and remove the `index.html` injection — the
-   fork now does denoise in-source. Keep shipping the `denoise/` assets (the
-   fork loads `./denoise/…` at runtime) until those move into the fork build.
-5. Re-run `LOTUS_TESTING.md` §D for each feature; only then ship.
-
-### 12.2 Holistic multi-agent review — outstanding follow-ups (non-blocking)
-
-Four aspect-agents reviewed the whole fork. Criticals were fixed in-branch (the
-denoise restart-silence/A7 bug; the `lotusDenoiseBase` code-load vector;
-audio-inject opt-in gate; #6 rendering in the wrong component; #7 simulcast cap).
-Remaining, deliberately deferred:
-
-- **Denoise H2 (double-processing):** if cinny is set to `lotusDenoise=ml` while
-  ALSO still injecting its build-time `getUserMedia` shim, audio is denoised
-  twice. The #1 cutover MUST remove the cinny-side injection (it currently has
-  none injected into the iframe — keep it that way). Hard requirement, not code.
-- **Denoise M1 (perf):** in-source uses non-SIMD `rnnoise.wasm`; the reference
-  preferred SIMD with detection. Perf-only; add SIMD detection later.
-- **dtln/deepfilternet (F3): RESOLVED** — all four models
-  (rnnoise/speex/dtln/deepfilternet) are now implemented in
-  `lotusDenoiseProcessor.ts` (faithful port of cinny's `build/lotus-denoise.js`
-  pipeline). This also fixed a real bug (the gate worklet name was `noiseGate`;
-  correct is the hyphenated `noise-gate`) and added per-model sample rates
-  (DTLN 16 kHz, others 48 kHz), context `resume()`, and SIMD wasm selection.
-  Still needs live §D testing per model, and depends on cinny shipping the
-  DTLN (`denoise/workadventure/`) + DeepFilterNet (`denoise/deepfilternet/`)
-  asset trees (it already does).
-- **Rebase-fragility (build agent MED):** the `CallViewModel` spotlight override
-  edits hot upstream lines (renamed `spotlightSpeaker$`→`autoSpotlightSpeaker$`).
-  For cheaper future rebases, refactor it into a `src/lotus/lotusSpotlight.ts`
-  wrapper that takes the upstream stream and returns the overridden one, leaving
-  upstream's definition byte-identical (a single import + two token swaps).
-- **Denoise asset coupling (build agent HIGH):** the fork loads `./denoise/*`
-  shipped by cinny, not by the fork build (documented in the processor). Add an
-  integration smoke-check that `GET …/element-call/denoise/rnnoise.wasm` == 200,
-  and pin the `@sapphi-red/web-noise-suppressor` version both repos expect.
-- **Unconditional effect registration (build agent LOW):** focus/audio-inject/
-  quality/decorations register widget handlers on every embedded call (true
-  no-ops for a non-Lotus host). Intentional; gate behind a coarse `lotus=1` flag
-  if strict zero-footprint is desired.
-- **Privacy (security agent):** decoration/inject URLs accept any `https`; ideally
-  restrict to the homeserver media origin host-side. Call-state exposes
-  userId/deviceId/speaking to the (trusted, same-origin) host — documented.
-
-**Nothing here blocks the §D live test — but every feature still needs it.**
-
-### 12.3 Safe rollout when prod is the only test environment
-
-Every Phase-2 feature is now **dormant by default** — with the flags cinny sets
-today, the fork behaves identically to the parity build (`#1` was decoupled onto
-`lotusDenoiseSource=1` so it no longer collides with the host's `lotusDenoise=ml`
-shim). This enables a low-risk incremental rollout even without a staging env:
-
-1. **Ship dormant first.** Publish the `lotus` branch (e.g. `0.20.1-lotus.1`),
-   bump cinny's pin, deploy. With no Lotus flags set / no Lotus actions sent,
-   this is upstream-equivalent (only inert, holistically-reviewed code runs).
-   "Testing" here = confirm a normal call still works.
-2. **Enable ONE feature at a time**, each independently revertable:
-   - URL-flag features (#2 `lotusCallState`, #5 `lotusTransparent`/`lotusTheme`,
-     #1 `lotusDenoiseSource`): add the flag in `CallEmbed.getWidget`, deploy,
-     test that one feature, roll back just that flag if needed.
-   - Action features (#3,#4,#6,#7): wire the host send + (for #2) the
-     `listenAction` ack, gated on join (§12.1 F1).
-3. **#1 denoise cutover is a coordinated 2-step** (do together): set
-   `lotusDenoiseSource=1` AND remove the `lotusDenoise()` shim injection +
-   `lotusDenoise=ml` param in cinny — otherwise audio is denoised twice.
-   Roll back = revert both.
-4. Baseline is always upstream-equivalent, so any single feature can be disabled
-   by flipping its flag/send off without touching the rest.
-
-**Blocker to step 1:** publishing the `lotus` branch needs a Gitea npm token
-(the admin token used for the `0.20.1` parity publish was deleted). Either
-provide a token for a manual `npm publish`, or stand up the Gitea Actions runner
-
-- `GITEA_NPM_TOKEN` secret so a `v0.20.1-lotus.1` tag auto-publishes.

-## 🧩 Element Call source-level items — now actionable via the fork
-
-> 🔱 **[EC-FORK]** **UPDATE 2026-06-30: Phase 2 IMPLEMENTED.** We own and
-> self-build Element Call (`LotusGuild/element-call` →
-> `@lotusguild/element-call-embedded@0.20.1-lotus.1`, cinny wired). A5/A6/A7
-> below are **fixed in the fork** — they are now ⚠️ awaiting **live
-> verification** (`LOTUS_TESTING.md` §D2), not open work. See
-> [`HANDOFF_ELEMENT_CALL_FORK.md`](./HANDOFF_ELEMENT_CALL_FORK.md) §10. Delete each
-> row once verified live.
-
-The in-call participant grid is rendered **inside EC's app** — now editable source
-(previously a prebuilt npm bundle we could only style around). Status of the items
-from testing:
-
-- **A5 — "Focus camera": ⚠️ FIXED in fork, awaiting verify (D2-3).** cinny now
-  sends an `io.lotus.focus_participant` widget action that pins a participant in
-  EC's layout (coexisting with / overriding the screenshare spotlight); the old
-  `.click()`-the-tile DOM hack in `CallControl.ts` is deleted.
-- **A6 — avatar decorations in-call: ⚠️ FIXED in fork, awaiting verify (D2-4).**
-  cinny pushes `io.lotus.decorations` (per-user APNG URLs) and the fork renders
-  them on EC's participant video-tile avatars — not just our pre-join lobby roster.
-- **A7 — mic dead after EC's "Reconnect": ⚠️ FIXED in fork, awaiting verify
-  (D2-1).** Denoise moved into EC's mic-capture/publish pipeline as a first-class
-  LiveKit `TrackProcessor` (flag `lotusDenoiseSource=1`); EC re-runs it on every
-  (re)publish, so reconnects keep denoise alive natively. The build-time
-  `getUserMedia`/`index.html` injection (the root cause) is removed. **Highest
-  blast radius — everyone's mic; verify D2-1 carefully.**

-## 🔴 Open — Actionable
-
-### 🧨 Encryption / E2EE — ⚠️ EXTREME COMPLEXITY · 🧠 PLANNING SESSION REQUIRED · 👤 SENIOR ENGINEER
-
-> 🧰 **Investigation kit ready (2026-07):** [`LOTUS_E2EE_INVESTIGATION.md`](./LOTUS_E2EE_INVESTIGATION.md)
-> has the per-KE capture runbook (console signatures, synapse-side queries, the
-> KE-1→KE-2 causality decision tree, ranked remediations), and the client now
-> ships a **Crypto Diagnostics** capture helper (Settings) — run it during the
-> next affected call and download the report before starting any fix.
-
-> **Observed live in prod 2026-06-30** on `chat.lotusguild.org` during a 2-person
-> **Element Call** (E2EE enabled). These span **client rust-crypto (via
-> `matrix-js-sdk@41.6.0-rc.0`) ↔ Synapse ↔ Element Call's MatrixRTC E2EE** and are
-> very likely **interrelated** (see KE-1 → KE-2). Do **not** spot-fix — they need
-> a dedicated cross-system planning session with the homeserver owner. Capture
-> full client console + a synapse-side trace for the same call before starting.
-> **None of these are caused by the EC fork work** (the issues reproduce on the
-> old build; the local mic/denoise path is unrelated to key distribution).
-
-- **KE-1 — One-time-key (OTK) upload conflict storm (CRITICAL, root-cause candidate).**
-  `POST /_matrix/client/v3/keys/upload` returns `400 M_UNKNOWN: One time key
-signed_curve25519:AAAAAAAAAGQ already exists. Old key: {…} new key: {…}` —
-  firing **continuously** (many/sec). The client repeatedly tries to publish an
-  OTK at a key id the server already holds **with a different value**, i.e. the
-  rust-crypto key store and Synapse have **diverged OTK state**. Impact: floods
-  the crypto outgoing-request loop and is the prime suspect for the downstream
-  missing-key failures (no fresh OTKs ⇒ no new Olm sessions ⇒ undecryptable
-  to-device key events). _Investigate:_ device/key-store reset-or-restore
-  mismatch, OTK id-counter desync, RC-SDK (`41.6.0-rc.0`) regression, or a
-  Synapse OTK bug. Repro signature: grep console for `already exists`.
-  **Extreme — planning session.**
-
-- **KE-2 — Element Call media keys not arriving/decrypting → audio & video cut out (CRITICAL).**
-  `MissingKey: missing key at index N for participant @user`, `skipping decryption
-due to missing key`, `MissingKey: key set not found for @user at index 0`, and
-  rust-crypto `WARN … Received an unexpected encrypted to-device event …
-event_type="io.element.call.encryption_keys"`. EC distributes per-participant
-  media keys as **encrypted to-device `io.element.call.encryption_keys`** events;
-  these aren't being received/decrypted in order, so remote LiveKit audio/video
-  can't be decrypted — **this is the "friend's audio cuts out occasionally"
-  symptom.** Almost certainly downstream of **KE-1** (broken Olm sessions). Spans
-  EC's MatrixRTC E2EE + rust-crypto to-device + Synapse. **Extreme — planning
-  session.**
-
-- **KE-3 — Timeline decryption error: missing `algorithm` field (HIGH).**
-  `Error decrypting event (… type=m.room.encrypted …): DecryptionError[msg:
-missing field 'algorithm' at line 1 column 138 …]`. A malformed/legacy
-  encrypted event (or a serialization mismatch in the RC SDK) that rust-crypto
-  can't parse. Lower frequency than KE-1/2 but a distinct decode-path failure —
-  capture the offending event id (`$SASBBzoqj…` seen) and inspect its raw content.
-
-- **KE-4 — MatrixRTC delayed-event / membership timeouts (MEDIUM-HIGH, reliability).**
-  `[MembershipManager] Network local timeout error while sending event, immediate
-retry … AbortError: Restart delayed event timed out before the HS responded`,
-  with repeated `org.matrix.msc4157.update_delayed_event`. MSC4140/4157
-  delayed-event reliability against `matrix.lotusguild.org` — can cause stale/ghost
-  call membership and missed leave events. May be partly **homeserver
-  responsiveness**; correlate with synapse latency/load. Include in the same
-  planning session since it shares the call-reliability + HS-interaction surface.
-
-### Security & Privacy
-
-- **N97 — Access token stored in plaintext `localStorage`** (`state/sessions.ts`), vulnerable to XSS; device ID likewise. Architectural — needs a token-protection / session-storage redesign.
-- **Session writes are non-atomic and not cross-tab synced** (`state/sessions.ts`) — risks inconsistent state / races across tabs.
-- **Persisted PII without encryption:** user status message + expiry (`settings/account/Profile.tsx`), unsent composer drafts (`room/RoomInput.tsx`). Leak risk on shared devices.
-
-### PWA / Offline / Notifications
-
-- **N107 — SW has no `push` handler** — Web Push delivery is entirely non-functional. Needs a `push` listener + a Matrix push-gateway integration.
-- **No app-asset caching strategy** (`src/sw.ts`) — no offline capability.
-- ~~**`manifest: false`** may block PWA install~~ — **verified OK (2026-06):** `index.html` links `/manifest.json`, which exists in `public/` and is copied to `dist/`; VitePWA intentionally doesn't generate one. Not a bug.
-
-### Dependencies & Build
-
-- **`matrix-js-sdk` pinned to a Release Candidate** (`41.6.0-rc.0`); `@atlaskit` and build tools (`vite`, `typescript`, `eslint`) on unstable/experimental pins — review for stable versions; RC SDK is a tree-shaking/bundle-size risk.
-- **Build-time overhead:** `lotusDenoise` does heavy sequential `fs` work in `closeBundle`; `viteStaticCopy` config is complex with redundant renames — could be streamlined.
-
-### Code Hygiene / DevEx
-
-- **Automated test suite — 561+ tests across 65+ modules, a hard CI gate.** `npm test` runs Node's built-in runner via `tsx` (not vitest — Vite 8 is ahead of vitest's range) and **blocks the build job on failure**. Broad pure-logic coverage: utils (common, regex, sanitize/XSS, time, matrix, matrix-uia, mimeTypes, sort, accentColor, findAndReplace, AsyncSearch, ASCIILexicalTable, keyboard, room, matrix-crypto, featureCheck, syntaxHighlight, imageCompression, user-agent, callSounds), state (settings, sessions, recentSearches, upload, typingMembers, lists, room-list, toast, scheduledMessages, backupRestore, callEmbed/callPreferences, spaceRooms, …), plugins (matrix-to, call/utils, via-servers, bad-words, recent-emoji, custom-emoji, markdown block/inline/utils), OIDC (cs-api, useParsedLoginFlows, oidcState), lotus/avatarDecorations, message-search, search filters. Prevention work has caught + fixed **4 real bugs** (`findAndReplace` infinite-loop; `getSettings` crash-on-load when storage is blocked; `isMacOS` never matching modern Macs; `isMLDenoiseSupported` throwing `ReferenceError` instead of returning false on browsers lacking the `AudioWorkletNode` binding). **Next:** component/integration tests (the untestable-under-tsx DOM/React surface).
-- **Extensive `as any` casts** across `src/` — gradual typing cleanup.
-- **`types/matrix/` mirrors SDK types** instead of importing them — drift risk.
-- ~~**Hardcoded CDN URL** should move to an env var~~ — **done:** `avatarDecorations.ts` already honors a `VITE_DECORATION_CDN` env override (lines 14-16); the in-repo literal is only the default. Nothing left.
-- **`patch-folds.mjs` edits `node_modules` directly** — consider `patch-package`.
-- **Infra docs:** `contrib/nginx` lacks security headers (HSTS/CSP) + uses rewrites over `try_files`; `contrib/caddy` has a placeholder path. CI/CD (`prod-deploy.yml`): sequential deploy, aggressive 1-min Netlify timeout, `package-manager-cache: false`.
-- **README:** keep the fork-sync version + logo path current. (`CONTRIBUTING.md` is intentionally left as upstream Cinny's — not a Lotus concern.)
-- **Architecture notes (low priority):** deep `features/` + `hooks/` nesting, many small coupled hooks, possible dead CSS/components, `SpacingVariant` / `DropTarget` recipe simplification.
-- **Git workflow (forward-looking):** keep commits scoped — past monolithic "fix all bugs" commits and inconsistent prefixes hurt `git bisect`.
-
-### Big Projects
-
-- ~~**#5 — Seasonal themes & chat-background redesign.**~~ **DONE (2026-06/07):** 11 seasonal/holiday overlays shipped and later toned down + given a settings preview grid; all 19 chat backgrounds redesigned (Carbon + Aurora kept per user preference), one design sprint each, GPU-friendly CSS with `prefers-reduced-motion` + pause toggle. Remaining polish rides normal bug flow, not a "big project."

-## 0. Deployment facts used by this runbook
-
-From the matrix infra README (`/root/code/matrix/README.md`):
-
-| Thing | Value |
-|-------|-------|
-| Synapse host | LXC **151**, `10.10.10.29` (Synapse 1.155.0) |
-| Synapse log | `/var/log/matrix-synapse/homeserver.log` |
-| Synapse config | `/etc/matrix-synapse/homeserver.yaml` (+ `conf.d/`) |
-| Synapse HTTP | `10.10.10.29:8008` |
-| PostgreSQL host | LXC **109**, `10.10.10.44` (PG 17.9), db `synapse` |
-| synapse-admin UI | `http://10.10.10.29:8080` |
-| LiveKit / lk-jwt / guard | LXC 151: LiveKit `:7880/:7881`, guard `:8070`, lk-jwt `:8071` |
-| SSH path to Synapse | `ssh root@10.10.10.4` then `pct enter 151` |
-| SSH path to PG | `ssh root@10.10.10.4` then `pct enter 109` |
-
-**Getting a psql shell** (run on LXC 109, or from 151 over the network):
-
-```bash
-# On LXC 109:
-sudo -u postgres psql synapse
-# From LXC 151 (pg_hba allows 10.10.10.29):
-psql "host=10.10.10.44 user=synapse dbname=synapse"
-```
-
-**Tailing Synapse during a call** (on LXC 151):
-
-```bash
-tail -F /var/log/matrix-synapse/homeserver.log | tee /tmp/lotus-call-$(date +%s).log
-```
-
-Synapse E2EE/to-device logging is chatty at `INFO`; if a category is silent,
-temporarily raise it in `/etc/matrix-synapse/conf.d/log.yaml` (or the
-`log_config` file referenced by `homeserver.yaml`):
-
-```yaml
-loggers:
-  synapse.rest.client.keys:            { level: DEBUG }
-  synapse.handlers.e2e_keys:           { level: DEBUG }
-  synapse.storage.databases.main.end_to_end_keys: { level: DEBUG }
-  synapse.handlers.devicemessage:      { level: DEBUG }   # to-device
-```
-
-Then `systemctl reload matrix-synapse` (reload re-reads log config without a
-full restart). **Revert to `INFO` after the capture** — DEBUG is very verbose.

-## 1. Per-KE evidence matrix
-
-Client greps assume Chrome/Firefox DevTools console (filter box or, better,
-"Preserve log" + save-as). The **Crypto Diagnostics** card (Settings →
-Developer Tools) auto-captures every signature below into a downloadable JSON —
-use it as the primary client artifact and DevTools as the raw backup.
-
-### KE-1 — OTK upload conflict storm (root-cause candidate)
-
-- **Console signature (grep):**
-  - `already exists`
-  - full: `POST /_matrix/client/v3/keys/upload … 400 M_UNKNOWN: One time key signed_curve25519:<id> already exists. Old key: {…} new key: {…}`
-- **Capture client-side:**
-  - Timestamp (first occurrence + rate — "N/sec"), **device id**, **user id**.
-  - DevTools → **Network** → filter `keys/upload`: for a failing call save the
-    **request body** (the `one_time_keys` map — note the exact `signed_curve25519:<id>`)
-    and the **response body** (the `Old key` / `new key` JSON). This diff is the
-    smoking gun: same key-id, different value ⇒ store vs server divergence.
-  - Whether it self-heals or loops forever (KE-1 loops).
-- **Synapse log grep (LXC 151):**
-  ```bash
-  grep -E "keys/upload|One time key .* already exists|OneTimeKey" \
-    /var/log/matrix-synapse/homeserver.log | grep "<user_id>"
-  ```
-- **Synapse SQL (LXC 109) — what the server thinks it holds:**
-  ```sql
-  -- Current OTK inventory for the device (compare key_id set against the
-  -- request body the client keeps retrying).
-  SELECT algorithm, key_id, ts_added_ms
-  FROM e2e_one_time_keys_json
-  WHERE user_id = '@user:matrix.lotusguild.org'
-    AND device_id = '<DEVICE_ID>'
-  ORDER BY algorithm, key_id;
-
-  -- Server's advertised counts (this is what /sync tells the client it has,
-  -- and drives whether the client decides to upload more).
-  SELECT algorithm, count(*) FROM e2e_one_time_keys_json
-  WHERE user_id = '@user:matrix.lotusguild.org' AND device_id = '<DEVICE_ID>'
-  GROUP BY algorithm;
-
-  -- Fallback key state (used when OTKs are exhausted).
-  SELECT algorithm, key_id, used, ts_added_ms
-  FROM e2e_fallback_keys_json
-  WHERE user_id = '@user:matrix.lotusguild.org' AND device_id = '<DEVICE_ID>';
-  ```
-  > Table names are Synapse 1.155 (`e2e_one_time_keys_json`,
-  > `e2e_fallback_keys_json`). If a name is absent, list with `\dt e2e*` in psql.
-- **Confirms:** if the offending `key_id` (from the 400) is **present** in
-  `e2e_one_time_keys_json` with a **different** stored value than the client's
-  request body → OTK state has diverged (rust-crypto store vs Synapse). That is
-  the KE-1 root condition.
-
-### KE-2 — EC media keys not arriving/decrypting (audio/video cutouts)
-
-- **Console signature (grep):**
-  - `MissingKey`
-  - `missing key at index` (e.g. `MissingKey: missing key at index N for participant @user`)
-  - `key set not found`
-  - `io.element.call.encryption_keys` (rust-crypto: `WARN … Received an unexpected encrypted to-device event … event_type="io.element.call.encryption_keys"`)
-- **Capture client-side:**
-  - Timestamp windows where a participant's audio/video cut out, and the
-    `@participant` + `index N` from the message.
-  - The `io.element.call.encryption_keys` warnings (these are the media-key
-    to-device events failing to decrypt) with their timestamps.
-  - Own device id + user id (to correlate with the sender's Olm session).
-- **Synapse log grep (LXC 151) — to-device delivery of the media keys:**
-  ```bash
-  grep -E "io.element.call.encryption_keys|m.room.encrypted|/sendToDevice|to_device" \
-    /var/log/matrix-synapse/homeserver.log | grep -E "<user_id>|<participant_id>"
-  ```
-- **Synapse SQL (LXC 109) — undelivered / queued to-device events:**
-  ```sql
-  -- Backlog of to-device messages queued for the affected device. A growing
-  -- count here = the HS has the media-key events but the device isn't draining
-  -- them via /sync (or they were sent to a stale device id).
-  SELECT user_id, device_id, count(*) AS pending
-  FROM device_inbox
-  WHERE user_id = '@user:matrix.lotusguild.org'
-  GROUP BY user_id, device_id;
-
-  -- Cross-check the device id the sender is targeting actually exists / is current.
-  SELECT device_id, display_name, last_seen, ts
-  FROM devices WHERE user_id = '@user:matrix.lotusguild.org';
-  ```
-- **Confirms:** to-device events present but undecryptable (client shows the
-  `io.element.call.encryption_keys` "unexpected encrypted" warning) ⇒ there is
-  **no valid Olm session** to decrypt them — the expected downstream of KE-1.
-
-### KE-3 — Timeline decryption error: missing `algorithm` field
-
-- **Console signature (grep):**
-  - `DecryptionError`
-  - full: `Error decrypting event (… type=m.room.encrypted …): DecryptionError[msg: missing field 'algorithm' at line 1 column 138 …]`
-- **Capture client-side:**
-  - The **event id** (`$SASBBzoqj…` was one) and the **room id**.
-  - Pull the raw event JSON via DevTools or the Developer Tools account-data/event
-    viewer, or directly:
-    ```
-    GET https://matrix.lotusguild.org/_matrix/client/v3/rooms/<roomId>/event/<eventId>
-    ```
-    Inspect `content` — confirm whether `algorithm` (should be
-    `m.megolm.v1.aes-sha2`) is truly absent vs a serialization mismatch.
-- **Synapse log grep (LXC 151):**
-  ```bash
-  grep -E "<eventId>" /var/log/matrix-synapse/homeserver.log
-  ```
-- **Synapse SQL (LXC 109) — the stored event content as the HS holds it:**
-  ```sql
-  SELECT ej.event_id, e.type, e.sender, e.origin_server_ts,
-         (ej.json::json -> 'content' -> 'algorithm') AS algorithm
-  FROM event_json ej
-  JOIN events e USING (event_id)
-  WHERE ej.event_id = '$SASBBzoqj...';
-  ```
-- **Confirms:** if the stored `content.algorithm` is **NULL/absent** on the HS →
-  a malformed/legacy event was persisted (sender-side or federation). If it is
-  **present** on the HS but the client throws → an RC-SDK deserialization bug.
-  This distinction decides whether KE-3 is a data problem or a client problem.
-
-### KE-4 — MatrixRTC delayed-event / membership timeouts
-
-- **Console signature (grep):**
-  - `update_delayed_event` (`org.matrix.msc4157.update_delayed_event`)
-  - `delayed event` / `Restart delayed event timed out`
-  - full: `[MembershipManager] Network local timeout error while sending event, immediate retry … AbortError: Restart delayed event timed out before the HS responded`
-- **Capture client-side:**
-  - Timestamps of each timeout; whether they correlate with call join/leave or
-    with general sync slowness.
-  - DevTools → Network: the `…/delayed_events…` / `update_delayed_event`
-    requests — their **HTTP status and latency** (timed-out vs slow-200).
-- **Synapse log grep (LXC 151):**
-  ```bash
-  grep -E "delayed_event|msc4140|msc4157|update_delayed" \
-    /var/log/matrix-synapse/homeserver.log | grep "<user_id>"
-  # HS responsiveness in the same window (KE-4 may be pure latency):
-  grep -E "Processed request|/sync" /var/log/matrix-synapse/homeserver.log | tail -50
-  ```
-- **Server-side corroboration (Grafana, `dashboard.lotusguild.org`):** Synapse
-  p99 response time (excl. `/sync`), event-processing lag, DB query latency for
-  the call window. High latency here ⇒ KE-4 is (partly) homeserver
-  responsiveness, not a client bug.
-- **Confirms:** timeouts that line up with HS latency spikes → reliability/load;
-  timeouts with a healthy HS → client MembershipManager retry logic.

-## 2. Causality hypothesis
-
-```
-KE-1  OTK upload conflict storm
-      (rust-crypto store ↔ Synapse OTK state DIVERGED; server rejects re-uploads)
-        │  no fresh OTKs can be published/claimed
-        ▼
-      No new Olm (1:1) sessions can be established with this device
-        │
-        ▼
-KE-2  EC media-key to-device events (io.element.call.encryption_keys)
-      arrive but cannot be decrypted  ⇒  MissingKey at index N
-      ⇒  friend's audio/video cuts out
-```
-
-KE-3 (missing `algorithm`) and KE-4 (delayed-event timeouts) are **likely
-independent** of the KE-1→KE-2 chain: KE-3 is a decode/serialization path,
-KE-4 is a MatrixRTC-vs-HS reliability path. Confirm/refute independence with the
-decision tree below.
-
-### Decision tree — which capture confirms/refutes each link
-
-```
-Q1. Does the KE-1 offending key_id from the 400 response exist in
-    e2e_one_time_keys_json with a DIFFERENT value than the client request body?
-    ├─ YES → OTK divergence CONFIRMED (KE-1 root). Go to Q2.
-    └─ NO  → Not divergence. Check: are OTK counts at 0 with fallback key `used=true`?
-             ├─ YES → OTK exhaustion, not divergence — different remediation.
-             └─ NO  → Suspect RC-SDK 41.6.0-rc.0 upload-loop regression (see §3).
-
-Q2. During the same call, are io.element.call.encryption_keys to-device events
-    present in device_inbox / Synapse to-device logs for our device id?
-    ├─ YES + client shows "unexpected encrypted"/MissingKey
-    │        → KE-1 ⇒ KE-2 LINK CONFIRMED (events delivered, no Olm session to open them).
-    ├─ YES + client decrypts fine, but LiveKit still silent
-    │        → KE-2 is downstream of LiveKit/SFU, NOT KE-1. Decouple from crypto.
-    └─ NO (nothing queued/targeted our device)
-             → media keys never sent to us: stale device id / membership (see KE-4)
-               → KE-2 is a device-targeting problem, weakly linked to KE-1.
-
-Q3. KE-3: is content.algorithm NULL in event_json on the HS?
-    ├─ YES → malformed persisted event (sender/federation). Independent of KE-1.
-    └─ NO  → client-side RC-SDK deserialization bug. Independent of KE-1.
-
-Q4. KE-4: do delayed-event timeouts coincide with Synapse p99 latency spikes
-    (Grafana) in the same minute?
-    ├─ YES → homeserver responsiveness/load. Independent of KE-1..KE-3.
-    └─ NO  → client MembershipManager retry behavior. Independent.
-```

----
-
-## 3. Ranked remediation options (with blast radius)
-
-> Ordered least-destructive → most-destructive. **Do not run any of these as a
-> "fix" before the planning session** — they are listed so evidence collection
-> can be paired with a recovery plan. Confirm the root condition (Q1/Q2) first.
-
-1. **Per-device logout + re-login of the affected device** *(lowest blast radius)*
-   - **What:** log the one glitching device out and back in. Forces a fresh
-     device id, fresh device keys, and a clean OTK batch — sidesteps a diverged
-     OTK store without touching other sessions.
-   - **Blast radius:** that device only. Other sessions/devices untouched.
-   - **Cost:** the new device must be re-verified (cross-signing) and will need
-     to restore room keys from **key backup** to read old encrypted history.
-   - **Confirms/uses:** if KE-1 stops after this, OTK-store divergence (Q1) was
-     the cause.
-
-2. **Client crypto-store reset (`clearLoginData` path)** *(medium)*
-   - **What:** `clearLoginData()` in `src/client/initMatrix.ts` (coordinator's
-     file — do not edit) **deletes ALL IndexedDB databases** (incl.
-     `web-sync-store` and the rust-crypto store `crypto-store`), **unregisters
-     service workers**, **clears all Cache Storage**, and **`localStorage.clear()`**,
-     then reloads. `clearCacheAndReload()` is lighter — it only calls
-     `mx.store.deleteAllData()` (sync cache) and does **not** wipe crypto.
-   - **Blast radius:** this browser profile only, but total: you are logged out,
-     lose all cached sync state, drafts, settings, and **the local
-     megolm/room-key store**.
-   - **⚠️ Message-history / backup implication:** wiping `crypto-store` destroys
-     locally-held **room keys (megolm inbound sessions)**. Any history **not
-     backed up to server-side Key Backup** becomes **permanently undecryptable
-     on this device**. Before doing this: verify Key Backup is enabled and the
-     recovery key / passphrase is available (Settings → Security), or the user
-     loses readable history. Cross-signing must be re-established too.
-   - **Use when:** the rust-crypto store itself is corrupt/diverged and option 1
-     didn't clear it.
-
-3. **SDK pin change off the RC** *(medium — codebase change, needs rebuild)*
-   - **Current pin:** `package.json` → `"matrix-js-sdk": "41.6.0-rc.0"` (a
-     release candidate).
-   - **Finding (npm / GitHub changelog, checked 2026-07):** stable **`41.6.0`**
-     was released **2026-05-26**. Its only changelog line is *"Throw sane error
-     on completeLoginOnNewDevice IdP rejection"* — **no OTK / keys-upload / Olm /
-     to-device fix** relative to the RC. Later stable lines exist
-     (`41.7.0`, `41.8.0`; `41.7.0-rc.3` / `41.9.0-rc.0` seen as pre-releases).
-     Nearby crypto-relevant entries: `41.5.0` *"Enable encrypted history sharing
-     by default"*; `41.4.0` key-backup handling. **No changelog entry directly
-     addresses the KE-1 OTK-conflict symptom** in the immediate range — so
-     moving RC→`41.6.0` stable is a low-risk hygiene step but is **not expected
-     to fix KE-1 by itself**. Before pinning, re-read the CHANGELOG for any
-     `41.7.x`/`41.8.x` OTK/one-time-key/olm entry that post-dates this note.
-   - **Blast radius:** all users after the next `cinny-build.sh` deploy. Test the
-     rust-crypto IndexedDB schema — a downgrade triggers the `IDB_VERSION_CONFLICT`
-     path in `initMatrix.ts`.
-
-4. **Synapse-side OTK row surgery** *(LAST RESORT — highest danger)*
-   - **What:** deleting/rewriting rows in `e2e_one_time_keys_json` (and/or
-     `e2e_fallback_keys_json`, `device_inbox`) for the affected device to force
-     the client to re-upload a clean batch.
-   - **⚠️ Danger:** direct writes to Synapse crypto tables can **desync every
-     device of that user**, break Olm sessions **for everyone who has claimed one
-     of those keys**, and are easy to get wrong (wrong `key_id`, cache not
-     invalidated). Synapse caches OTK counts — a raw DELETE without a restart can
-     leave the advertised count wrong, **worsening** the KE-1 loop.
-   - **Guardrails if ever done (planning session + HS owner only):** full
-     `pg_dump` of `synapse` first; do it during **zero active calls**; delete only
-     the exact diverged `key_id` for the exact `device_id`; `systemctl restart
-     matrix-synapse` to flush caches; then log the device out/in (option 1) so it
-     republishes. **Never** run this speculatively.
-
----
-
-## 4. "Capture session" checklist (run during the next call)
-
-Do these **in order**. Aim to have client + server capturing the **same call**.
-
-1. **Prep server tail (LXC 151):** SSH in, start
-   `tail -F /var/log/matrix-synapse/homeserver.log | tee /tmp/lotus-call-$(date +%s).log`.
-   (Optionally raise the `synapse.rest.client.keys` / `handlers.e2e_keys` /
-   `handlers.devicemessage` loggers to DEBUG per §0 and `systemctl reload
-   matrix-synapse` — remember to revert after.)
-2. **Prep client:** open Lotus Chat → Settings → Developer Tools → **enable
-   Developer Tools** so the **Crypto Diagnostics** card is visible; note its
-   entry count starts at (or reset by reload to) 0.
-3. **Open DevTools** (F12) → Console: enable **Preserve log**; Network tab:
-   enable **Preserve log** + **Record**. Note your **device id** and **user id**
-   (Settings → Devices / Developer Tools → Copy access token page shows ids).
-4. **Note wall-clock start time** (ISO/UTC) on both machines so logs align.
-5. **Join the Element Call** with the second participant; reproduce the fault
-   (wait for the audio/video cutouts and let KE-1 storm run ~30–60s).
-6. **When a fault occurs, note the wall-clock timestamp** and which symptom
-   (audio cut / video freeze / etc.) — this bounds the log window.
-7. **Client artifacts:** in the Crypto Diagnostics card click **Download report**
-   (`lotus-crypto-diag-<ts>.json`); in DevTools Network, save the failing
-   `keys/upload` request+response (right-click → Save/Copy), and the raw HAR
-   (Network → Save all as HAR) for the call window.
-8. **Grab KE-3 event id / KE-2 participant+index** from the console (or the
-   diag JSON `entries[]`) for the SQL lookups.
-9. **Server artifacts:** stop the tail; run the per-KE greps and SQL from §1
-   against the noted device id / user id / event id, saving output alongside the
-   client JSON. Screenshot the Grafana Synapse latency panels for the window
-   (for KE-4).
-10. **Bundle & label:** put client JSON + HAR + server log slice + SQL output in
-    one folder named with the call's UTC start time. Revert any DEBUG log config
-    (`systemctl reload matrix-synapse`). Hand off to the planning session — **do
-    not apply §3 remediations yet.**

-## 5. Client diagnostics helper (this kit)
-
-- **`src/app/utils/cryptoDiagLog.ts`** — capture-only console instrumentation.
-  - `installCryptoDiagLog()` — idempotent; wraps `console.warn`/`console.error`
-    with pass-through wrappers (originals always called) that ring-buffer (max
-    **200**) any line matching the KE signatures. No network, no timers.
-  - `getCryptoDiagEntries()` — snapshot copy of the buffer (`{ ts, level, ke,
-    signature, message }`, most-recent-last).
-  - `buildCryptoDiagReport(mx)` — JSON string: SDK version, device id, user id,
-    sync state, `cryptoReady` (`mx.getCrypto()` presence), per-KE counts, and the
-    entry buffer. No tokens/PII beyond those ids; captured log lines are retained
-    verbatim as evidence.
-  - **Signatures → KE mapping:** `already exists`→KE-1; `missing key at index` /
-    `io.element.call.encryption_keys` / `MissingKey`→KE-2; `DecryptionError`→KE-3;
-    `update_delayed_event` / `delayed event`→KE-4.
-- **`src/app/features/settings/developer/CryptoDiagnostics.tsx`** — a folds
-  `SequenceCard`/`SettingTile` card (mirrors `developer-tools/DevelopTools.tsx`)
-  showing the live matched-entry count (Badge) and a **Download report** button
-  (Blob → `lotus-crypto-diag-<ts>.json`, same download idiom as
-  `room-settings/ExportRoomHistory.tsx`).
-
-### Recommended mount points (coordinator)
-
-- **Install call:** call `installCryptoDiagLog()` **as early as possible during
-  boot** so it captures crypto errors from first sync — ideally at the top of
-  the client entry module or inside `ClientRoot` before/around `initClient`
-  (e.g. `src/app/pages/client/ClientRoot.tsx`). It is idempotent, side-effect
-  only, and needs no `mx`, so a module-scope call at app entry is safe. (Do
-  **not** put it in `initMatrix.ts` — that file is off-limits.)
-- **Settings card:** render `<CryptoDiagnostics />` inside the Developer Tools
-  page — in `src/app/features/settings/developer-tools/DevelopTools.tsx`, add it
-  to the `Box direction="Column" gap="700"` list (guarded by the existing
-  `developerTools` flag), right after the "Access Token" card. It pulls `mx`
-  from `useMatrixClient()` itself, so it just needs to be placed in the tree.

+**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).
+
+---

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

 ## ⚠️ TDS DESIGN LAW — READ BEFORE TOUCHING ANY UI
 
 > **ALL Lotus Terminal Design System (TDS) styling — colors, animations, glows, borders, fonts, spacing — MUST come exclusively from `/root/code/web_template/base.css` CSS variables.**
-> Do NOT hardcode hex values. Do NOT invent new variable names. Do NOT deviate from the design tokens defined in that file.
+> Do NOT hardcode hex values. Do NOT invent new variable names. Canonical tokens: `--lt-accent-orange`, `--lt-accent-cyan`, `--lt-accent-green`, `--lt-glow-*`, `--lt-box-glow-*`, `--lt-border-color`, `--lt-font-mono`. Syntax-highlight token classes: `.tok-kw .tok-str .tok-num .tok-cmt .tok-fn`.
-> The canonical variable reference: `--lt-accent-orange`, `--lt-accent-cyan`, `--lt-accent-green`, `--lt-glow-orange`, `--lt-box-glow-*`, `--lt-border-color`, etc.
+> Reference patterns: `/root/code/tinker_tickets/` (markdown.js, base.js, ticket.css). Applies to every task without exception.
-> Reference implementation for code patterns: `/root/code/tinker_tickets/` (markdown.js, base.js, ticket.css)
+> New components must respect both TDS dark (`LotusTerminalTheme`) and TDS light (`LotusTerminalLightTheme`); non-TDS theme work uses vanilla-extract (match `src/lotus-terminal.css.ts`).
-> This rule applies to EVERY task in this file without exception.

 ## 🧩 NATIVE-CINNY LAW — EVERY FEATURE MUST FEEL LIKE STOCK CINNY
 
-> **Every feature we implement must feel native to the upstream Cinny app — indistinguishable from something the Cinny team would have shipped.** Reference: <https://github.com/cinnyapp/cinny>.
+> **Every feature must feel native to upstream Cinny — indistinguishable from what the Cinny team would ship.** Reference: <https://github.com/cinnyapp/cinny>.
 >
-> Concretely this means:
+> - **Use the `folds` design system, not bespoke UI** (`Button`, `Chip`, `IconButton`, `Menu`, `MenuItem`, `Dialog`, `Modal`, `Input`, `Switch`, `Badge`, `SettingTile`, `SequenceCard`, …) and folds tokens (`color.*`, `config.space.*`, `config.radii.*`). **Use folds `Icon`/`Icons`, never literal emoji, in UI chrome.** No hardcoded hex/`rgba()`, no invented CSS variables.
->
+> - **Match Cinny's existing patterns** — find the closest existing component/flow and mirror it before adding UI.
-> - **Use the `folds` design system, not bespoke UI.** Build with folds primitives (`Button`, `Chip`, `IconButton`, `Menu`, `MenuItem`, `Dialog`, `Modal`, `Input`, `Switch`, `Badge`, `SettingTile`, `SequenceCard`, etc.) and folds tokens (`color.*`, `config.space.*`, `config.radii.*`, `config.borderWidth.*`). No hardcoded hex/`rgba()` for UI chrome, no invented/undefined CSS variables.
+> - **The ONE exception:** explicit **TDS** features, which follow the TDS Design Law above (opt-in, only in Lotus Terminal mode).
-> - **Match Cinny's existing patterns.** Before adding UI, find the closest existing Cinny component/flow and mirror it (e.g. a new dropdown uses `Button`+`PopOut`+`Menu`+`MenuItem` like the rest; a new modal has a `Header` with a close `IconButton`; a new setting is a `SettingTile` inside a `SequenceCard`). Consistency with stock Cinny beats personal style.
-> - **Lotus-custom additions should be unobtrusive** and fit Cinny's visual language, spacing, and interaction conventions — a stranger using Cinny should not be able to tell which features are ours.
->
-> **The ONE exception:** explicit **Lotus Terminal Design System (TDS)** features, which intentionally have their own distinct look and follow the **TDS Design Law** above. TDS styling is opt-in (only active in Lotus Terminal mode); everything else must look and feel like native Cinny.

+## ✅ Audit (2026-07) — closed out
+
+A three-wave feature bug-hunt (~15 parallel agents, each batch independently reviewed) plus a low-tail cleanup. All confirmed 🔴/🟠 and the clean 🟡 tail are **fixed, reviewed, and gate-green**; details in git history + LOTUS_FEATURES. Only the minor items below remain open.
+
+**Still open (low tail — all 🟡 minor):**
+
+- **Calls host:** C-M1 deafen DOM-fallback leaks late-added `<audio>` tracks; C-M2 `.click()`-by-testid toggles no-op if EC renames — **both retire via EC-fork P6-2**. C-L1 AFK mic not released if EC elides the echo; C-L2 ringtone-preview global cross-cancel; C-L3 first ring after cold load can be silent (ctx not unlocked); C-L5 speaker-observer churn on membership change; C-L7 all-muted DOM miscount if EC label format differs; C-L8 PiP sw/nw resize anchor jitter at min size.
+- **Threads:** T5 `participating` detection is server-bundle-only (`thread.hasCurrentUserParticipated`) → can under-notify a thread you just replied to; T6 room "Mentions & Keywords" not honored for participated/Default thread replies (over-notify); T7 account-data thread-mute write is a lost-update race.
+- **Crypto/session:** F5 OIDC refresh drops `expiresAt` on persist (`persistTokens` can't reach the expiry without SDK-internal plumbing; refresh is reactive on 401).
+- **Native/desktop:** D7 Unity badge `application://cinny.desktop` id may not match the installed `.desktop` basename — **runtime-verify** on the `.deb`/AppImage. H10 room-name setter fire-and-forget/silent length reject (trivial). N6 per-message read-receipt avatars may not refresh on membership change (emitter uncertain, low impact).
+- **EC fork (EC1–EC6 fixed on `element-call:lotus`, needs a republish):** re-apply `setTimeout` cleanup, remote-gated subscription → `allConnections$`, per-call decoration state leak, re-subscribe-every-render, focus-clear on missing `userId`. Rides with **P6-2 phase 2**.

+## 🔴 Open — Actionable
 
-- `[AUDIT REQUIRED]` — at least one assumption needs code/server verification before implementing
+### 🧨 Encryption / E2EE — ⚠️ EXTREME COMPLEXITY · 🧠 PLANNING SESSION REQUIRED
-- `[SERVER CHECK]` — depends on a Synapse feature or MSC; verify on `matrix.lotusguild.org`
-- `[LOW PRIORITY]` — implement after all higher-priority items
-- `[EXTREME COMPLEXITY]` — multi-sprint, plan separately before touching
-- `[BLOCKED]` — cannot build until a server upgrade, upstream MSC, or dependency resolves
-- `[IMPROVE]` — feature exists in upstream Cinny; this task enhances it for Lotus Chat
 
-Status: `[ ]` pending · `[~]` in progress · `[x]` completed
+Observed live in prod 2026-06-30 during a 2-person **Element Call** (E2EE). These span client rust-crypto (`matrix-js-sdk@41.7.0`) ↔ Synapse ↔ EC MatrixRTC E2EE and are **interrelated** — do NOT spot-fix. **Capture first:** run **Settings → Developer Tools → Crypto Diagnostics** during the next affected call + a synapse-side trace before any fix. (Full runbook was in `LOTUS_E2EE_INVESTIGATION.md`, now in git history.) None are caused by the EC fork work.
+
+- **KE-1 — OTK upload conflict storm (CRITICAL, root-cause candidate).** `POST /keys/upload` returns `400 M_UNKNOWN: One time key … already exists` continuously — the rust-crypto store and Synapse have **diverged OTK state** (upstream `matrix-rust-sdk#5200`, OPEN: on the 400 the SDK never marks the request sent → re-uploads forever; **not** fixed in 41.7.0). Leading web trigger: cinny never calls **`navigator.storage.persist()`**, so the IndexedDB crypto store is evictable while the `localStorage` session survives → device resurrects with a blank store. **Buildable preventive fix (no call needed):** request persistent storage on login (+ optional multi-tab guard + a 400-loop→recovery prompt). Healing an already-diverged device still needs a clean logout+login.
+- **KE-2 — EC media keys not arriving/decrypting → audio/video cut out (CRITICAL).** `MissingKey … for participant`, unexpected encrypted to-device `io.element.call.encryption_keys`. Almost certainly downstream of KE-1 (broken Olm sessions). This is the "friend's audio cuts out" symptom.
+- **KE-3 — Timeline decrypt error: missing `algorithm` field (HIGH).** rust-crypto can't parse a malformed/legacy encrypted event — capture the offending event id + raw content.
+- **KE-4 — MatrixRTC delayed-event / membership timeouts (MEDIUM-HIGH).** `Restart delayed event timed out`, repeated `msc4157.update_delayed_event` — may be partly HS responsiveness; correlate with synapse latency. Same planning session (shares the call-reliability surface).
+
+### Security & Privacy
+
+- **N97 — Access token + device id in plaintext `localStorage`** (`state/sessions.ts`), XSS-exposed. Architectural — needs a token-protection / session-storage redesign.
+- **Persisted PII without encryption:** user status message + expiry (`Profile.tsx`), unsent composer drafts (`RoomInput.tsx`). Leak risk on shared devices.
+
+### PWA / Offline / Web Push
+
+- **N107 — Web Push is non-functional:** `src/sw.ts` has no `push` handler. Needs a `push` listener + Matrix push-gateway integration. **The one substantive remaining feature** (session/crypto groundwork it waited on has landed).
+- **No app-asset caching strategy** in `src/sw.ts` — no offline capability.
+
+### Dependencies / Build / Hygiene
+
+- Build-time: `lotusDenoise` does heavy sequential `fs` in `closeBundle`; `viteStaticCopy` has redundant renames — could be streamlined.
+- `patch-folds.mjs` edits `node_modules` directly (robust today; `patch-package` considered but more brittle to folds restructuring — WON'T-DO unless it breaks).
+- `types/matrix/` mirrors SDK types instead of importing them — drift risk; spot-fix highest-risk only.
+- `contrib/nginx`/`contrib/caddy` examples: headers + `try_files` already synced with prod; the prod nginx `add_header` isn't inherited by cache `location` blocks (pre-existing; SPA entry `/` still gets all headers).
+- `as any` casts across `src/` — gradual typing cleanup. Keep commits scoped (bisect-friendly). Keep README fork-sync version/logo current.

-## Server Capabilities (as of June 2026)
+## 🌐 Matrix Protocol Gaps
 
-- **Homeserver:** `matrix.lotusguild.org`
+Genuine Matrix client-spec / MSC features Lotus does **not** yet implement (audited 2026-07 against the codebase — almost everything else is built: pinning, stickers+picker, room directory, mutual rooms MSC2666, blurhash, key backup/recovery/SSSS, SAS verification, ignore list, invite spam-filter, voice messages, polls, threads, spaces, OIDC, extended profiles, delayed events, authed media). Build each **fully** — spec-correct events, native-Cinny folds UI, tests. Order = clean wins first.
-- **Synapse version:** `1.155.0` (2026-06-18) — fully up to date; last version for Debian 12 (LXC 151 already on Debian 13 Trixie)
-- **Matrix spec:** up to `v1.12` formally; newer MSC features via `unstable_features`
 
-### Confirmed facts
+**Phase A ✅ (2026-07, gate-green 683 tests):**
 
-| Finding                                                                                                                                                  | Impact                                                                                                  |
+- [x] **Mark as Unread — MSC2867 `m.marked_unread`.** Room account data `{ unread: true }` (+ unstable `com.famedly.marked_unread`) via `mx.setRoomAccountData`; clear on read. Context-menu item in `RoomNavItem` + light the existing unread dot; integrate `state/room/roomToUnread.ts`.
-| -------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------- |
+- [x] **Low Priority rooms — `m.lowpriority` tag.** Mirror the favourite impl (`RoomNavItem.tsx:331-337` `setRoomTag/deleteRoomTag` + the favourites category in `home/Home.tsx`): context-menu toggle + a collapsed "Low Priority" category sorted to the bottom, excluded from normal unread nudging.
-| **MSC flags ON:** `msc4140` · `msc3771` · `msc3440.stable` · `msc4133.stable` · `simplified_msc3575` · `msc4222` · `msc3266` · `msc3401_matrix_rtc`      | All safe to use now                                                                                     |
+
-| **MSC flags OFF:** `msc4306` (thread subscriptions) · `msc3882` · `msc3912` · `msc4155`                                                                  | These features are BLOCKED                                                                              |
+**Phase B ✅ (2026-07, gate-green 688 tests):**
-| **MSC3266** room summary: flag `msc3266_enabled: true` set but `GET /v1/rooms/{id}/summary` still returns 404 (M_UNRECOGNIZED)                           | Room Preview BLOCKED — endpoint not implemented in Synapse 1.155                                        |
+
-| **MSC3892** relation redaction: not in flags                                                                                                             | Reaction Redaction feature BLOCKED                                                                      |
+- [x] **Disappearing Messages — MSC1763 `m.room.retention`.** PL-gated room-settings `SettingTile` to set `{ max_lifetime }`; retention badge; a client-side sweep hides/self-redacts own expired events (pattern like the mute-timer restore in `ClientNonUIFeatures.tsx`). True server deletion also wants Synapse `retention:` (LXC 151).
-| **MSC4260** report user: `POST /_matrix/client/v3/users/{userId}/report` returns **200** ✅                                                              | **Report User UNBLOCKED** — endpoint live since Synapse 1.133; ready to build                           |
+- [x] **QR Device Verification — reciprocate QR.** Add the QR path beside emoji-SAS in `components/DeviceVerification.tsx`: render with `qrcode.react` (already a dep), scan via `BarcodeDetector` (fallback `jsQR`); uses the SDK `VerificationRequest` QR/reciprocate support.
-| **MSC4151** report room: HTTP 405 on GET = endpoint exists (POST only)                                                                                   | Report Room live ✅                                                                                     |
+
-| `folds AvatarImage` does NOT accept children                                                                                                             | Add frame/overlay inside `UserAvatar.tsx` itself — optional `frameName` prop                            |
+**Phase C (Room Widgets ✅ 2026-07; Sliding Sync ❌ evaluated — parked):**
-| No in-app toast system exists (was)                                                                                                                      | Built `ToastProvider` + Jotai queue; at `App.tsx:65`                                                    |

-| `useUnverifiedDeviceCount()` hook exists                                                                                                                 | `src/app/hooks/useDeviceVerificationStatus.ts:65-106`                                                   |
+- [x] **Room Widgets — MSC1236 + widget API.** No general widget UI exists (only the PL entry `im.vector.modular.widgets`; the EC call widget is hardcoded). Read `im.vector.modular.widgets`/`m.widget` state, add an Add/Manage panel + sandboxed iframe renderer via `matrix-widget-api` — **extend the existing EC widget plumbing** (`plugins/call/CallEmbed.ts`). Enables Etherpad/notes/dashboards/integrations.
-| Voice player: `AudioContent.tsx:44-223`                                                                                                                  | Playback rate on hidden `<audio>` at line 217                                                           |
+- **[PARKED] Sliding Sync — MSC3575 / simplified MSC4186** (evaluated 2026-07, 3 research passes). Server side is GA (`simplified_msc3575`), but the **client** side is not viable for a safe rollout: matrix-js-sdk's `SlidingSync`/`SlidingSyncSdk` are `_internal_`/`@experimental` (Element shipped labs-only, never GA in ~2 yrs, moved to the Rust SDK); **presence isn't delivered over sliding sync** (regresses Lotus presence badges/rings/status); **no upstream Cinny impl** to follow; and Cinny's whole nav (sidebar/spaces/DM/unread) is derived from the **full local room set** (`allRoomsAtom` ← `mx.getRooms()`), so ~14 subsystems (4 core) need re-architecting to a server-windowed list. ~10% confidence a full rollout wouldn't break/regress (missing rooms/messages/unread = worst failure class). **Revisit only if we adopt the Rust SDK or accounts grow large enough that startup latency is a real complaint; an off-by-default experimental spike is possible but not recommended.** Full assessment: git plan history.

-## Priority 3 — Higher complexity / lower daily frequency
+## 🚫 Blocked Features (server / upstream gated)
 
-### [ ] P3-4 · Accessibility Improvements (WCAG 2.1 AA)
+Re-run `/_matrix/client/versions` + `unstable_features` after each Synapse upgrade.
 
-**What:** Comprehensive audit and fix pass targeting the critical user paths:
+- **[BLOCKED] Live Location Sharing** (MSC3489 + MSC3672 both `false`) — real-time GPS beacons over the existing static share.
-
+- **[BLOCKED] Reaction/Relation Redaction** (MSC3892 `false`) — remove a reaction without redacting the parent; current full-redaction fallback is acceptable.
-- Room list navigation (keyboard-only)
+- **[BLOCKED] Room Preview before joining** (MSC3266) — `GET /v1/rooms/{id}/summary` returns 404 `M_UNRECOGNIZED` on Synapse 1.155 despite `msc3266_enabled:true`.
-- Reading messages in the timeline (screen reader announces new messages)
+- **[BLOCKED] Thread Subscriptions** (MSC4306 `false`) — "Follow thread" button (depends on the shipped Thread Panel).
-- Composing and sending a reply
-- Opening and closing modals (focus trap, return focus)
-- ARIA labels on all icon-only buttons
-
-**Scope:** Do NOT attempt to make every corner of the app AA-compliant in one pass — focus on the golden path (open app → find room → read → reply → send).  
-**[AUDIT REQUIRED]** — Run an automated audit first: `npx axe-core` or browser DevTools accessibility tree. Document every violation before writing a single line of code. Prioritize by severity (critical > serious > moderate).
-
-**Investigation Findings:**
-
-- **Root Cause:** Inconsistent focus management, missing `aria-live` regions for dynamic timeline updates, and sparse global keyboard shortcuts.
-- **Approach:** Standardize `focus-trap-react` usage (reference `RoomNavItem.tsx`). Add `aria-live` regions to the timeline. Expand `useKeyDown.ts` for section navigation shortcuts.
-- **Complexity:** Medium-High (audit is the main work).

-### [~] P3-8 · Thread Panel (full side drawer) — IMPLEMENTED (2026-07), ⚠️ AWAITING LIVE QA
+## 📖 Reference
-
+
-Built per the design below (4-agent build + 2-agent review). Gates green (tsc/eslint/build/tests). **Release note: threaded replies no longer render inline in the main timeline — roots show a "N replies" chip that opens the panel.**
+### Server Capabilities (as of 2026-06)
-
+
-**Manual QA checklist (post-deploy):**
+- **Homeserver** `matrix.lotusguild.org` · **Synapse** `1.155.0` · **Matrix spec** up to `v1.12` (+ MSC `unstable_features`).
-1. Reply in Thread (message menu) → panel opens; send text/upload/emoji into it (appears pending → confirmed)
+- **MSC ON:** `msc4140` · `msc3771` · `msc3440.stable` · `msc4133.stable` · `simplified_msc3575` · `msc4222` · `msc3266` (flag on but v1 summary 404s) · `msc3401_matrix_rtc`. **OFF/blocked:** `msc4306` · `msc3882` · `msc3912` · `msc4155` · `msc3489`/`msc3672` · `msc3892`.
-2. Reply to a reply inside the panel → event carries `m.thread` + `m.in_reply_to` with `is_falling_back:false`
+- **Live endpoints:** Report User (MSC4260) **200** ✅ · Report Room (MSC4151) ✅.
-3. Main timeline: root + chip only (replies absent); chip count/time updates live; unread badge appears for others' thread replies and clears after viewing the panel
+- **Homeserver access (audits):** Synapse = LXC 151 (`pct exec 151 -- bash`), config `/etc/matrix-synapse/homeserver.yaml`. Web deploy = LXC 106. Voice guard = `voice-limit-guard.py` on LXC 151.
-4. Room badge clears via normal markAsRead even with unread threads (unthreaded receipt)
+- **SDK notes:** no arbitrary profile-field methods (use `mx.http.authedRequest()` for MSC4133); js-sdk can't per-room filter `/sync`; sanitizer strips `<math>`/MathML; SW exists at `src/sw.ts`; `getMatrixToRoom()` builds invite URLs; EC audio-inject unblocked via the fork's `io.lotus.inject_audio`.
-5. Reload: partitioning persists; encrypted-room threads decrypt (back-pagination too)
+
-6. Escape / × closes; mobile = fullscreen panel; switching rooms and back restores the open thread  
+### Key File Reference
-**What:** A right-side drawer for threaded conversations. Currently "Reply in Thread" exists but there is no panel to read or write thread replies.

+
-
+### Element Call fork — operational reference
-**[AUDIT REQUIRED]** — Deeply audit how `m.thread` relation events are currently stored and retrieved in the matrix-js-sdk. Understand the thread aggregation API: `GET /rooms/{roomId}/relations/{eventId}/m.thread`. Check if `RoomTimeline.tsx` currently filters out thread replies from the main timeline (it should — confirm).
+
-
+Fork = `LotusGuild/element-call` (branch `lotus`, from upstream tag `v0.20.1`); cinny consumes the npm package `@lotusguild/element-call-embedded` (built bundle copied into `public/element-call/`).
-**Investigation Findings:**
+
-
+**Publish a new version (manual; needs the Gitea npm token):** bump `embedded/web/package.json` (current unpublished `0.20.1-lotus.2`) → `pnpm run build:embedded` (Node 24, pnpm 10.33) → `cd embedded/web && npm version <tag> --no-git-tag-version && npm publish` (Gitea registry) → in cinny bump the `@lotusguild/element-call-embedded` pin (currently `0.20.1-lotus.1`) → `npm install` → build.
-- **Root Cause:** Current `m.thread` events are treated as standard `m.room.message` events and rendered in the main timeline.
+
-- **Approach:** Introduce new Jotai atom `activeThreadEventId`. Create `ThreadPanel.tsx`. Update `RoomTimeline.tsx` to filter out thread relations (`m.relates_to`). Implement aggregation fetch using `GET /rooms/{roomId}/relations/{eventId}/m.thread`. Use `thread.timelineSet` directly for the most accurate thread view.
+**`io.lotus.*` widget actions** (add new toWidget actions to the enum + `LOTUS_TO_WIDGET_ACTIONS` in `src/lotus/lotusActions.ts`; only send AFTER call-join or a 10s timeout fires):
-- **Complexity:** High.

Mute also suppresses the chip badge and subtracts the thread from the room's sidebar badge (client-side). Also fixed the underlying path: thread replies are notified via exactly one handler (room-level `ThreadEvent.NewReply`), with the main-timeline notifier + unread binder thread-guarded, and live badge refresh on `RoomEvent.UnreadNotifications`.
-
-**Manual QA checklist (post-deploy):**
-1. Friend replies in a thread YOU posted in → notification + sound; in a thread you never touched → silent (chip badge only)
-2. @mention in any thread → notified regardless of participation
-3. Set a thread to Mute → no notifications, chip badge gone (bell-mute glyph), room sidebar badge drops by that thread's count
-4. Set to All → every reply notifies; Mentions-only → only @mentions
-5. Second device shows the same per-thread modes (account-data sync)
-6. Room-level Mute still silences everything incl. thread overrides
-**Known caveats:** Mentions-only can under-notify in E2EE rooms (decision runs pre-decryption — same class as the existing notifier); muted-thread badge subtraction is Lotus-only (other clients still count them).

-### [ ] P4-2 · Thread Subscriptions (MSC4306) [BLOCKED]
-
-**Spec:** MSC4306 (Synapse experimental). Depends on Thread Panel (#P3-8).  
-**What:** "Follow thread" button to receive notifications for a thread you haven't posted in. Uses MSC4306 subscription endpoint.  
-**[SERVER CHECK]** — `org.matrix.msc4306 = false` on `matrix.lotusguild.org` — BLOCKED until server enables it.  
-**Complexity:** Medium (after thread panel exists).
-
----
-
-### [ ] P4-4 · Math / LaTeX Rendering in Messages (LOW PRIORITY)
-
-**Spec:** CS-API §11.5 (stable) — `formatted_body` can contain LaTeX.  
-**What:** Render `$...$` or `$$...$$` LaTeX expressions in message bodies. Use KaTeX (lightweight, ~100KB, renders server-side-compatible CSS). Must gracefully fall back to raw LaTeX text if KaTeX fails.  
-**Note:** This is LOW PRIORITY — only useful for academic/technical communities. Implement last.  
-**[AUDIT REQUIRED]** — Confirm KaTeX bundle size impact on the Vite bundle. Check if matrix-js-sdk's HTML sanitizer strips LaTeX before it reaches the renderer. The formatted_body sanitization pipeline is the main risk here. (Confirmed: sanitizer STRIPS `<math>` tags — must be patched alongside the renderer.)  
-**Complexity:** Low-Medium.
-
----
-
-### [ ] P4-5 · Live Location Sharing (MSC3489 + MSC3672) (LOW PRIORITY, HIGH COMPLEXITY) [BLOCKED]
-
-**Spec:** MSC3489 + MSC3672. Implemented in Element Web.  
-**Note:** Static location sharing is already implemented. This adds live/real-time GPS beacons. Very low priority per user preference.  
-**What:** Start sharing live location → creates `m.beacon_info` state event → client posts `m.beacon` events on a timer → other users see your position update live on a map.  
-**[SERVER CHECK]** — `org.matrix.msc3489 = false` AND `org.matrix.msc3672 = false` on `matrix.lotusguild.org` — BLOCKED.  
-**Complexity:** High. Requires background geolocation API + live map rendering.

-### [~] P4-6 · OIDC / SSO Next-Gen Auth (MSC3861) — CLIENT-SIDE BUILT, awaiting live verification
-
-**Spec:** MSC3861 / MSC2965, Matrix spec v1.15. OAuth2-native auth via a Matrix Authentication Service (MAS).  
-**Scope decision (2026-06):** CLIENT-ONLY. We implemented OIDC login _in the Lotus client_ so it can sign into next-gen homeservers (mozilla.org, eventually matrix.org). We deliberately did **not** convert lotusguild's own Synapse to MAS (no account migration; lotusguild keeps password + legacy Authelia SSO).  
-**Built (matrix-js-sdk already ships the OIDC API; this was wiring):**
-
-- Discovery: `cs-api.ts` `getOidcIssuer()` (stable `m.authentication` + msc2965). Flow hint: `useParsedLoginFlows` `getOidcCompatibilityFlag()` (MSC3824).
-- Login: `pages/auth/oidc/{oidcConfig,oidcLoginUtil,oidcState}.ts` (dynamic registration + cache, PKCE authorize), `login/OidcLogin.tsx`, issuer-gated `Login.tsx`.
-- Callback: `oidc/OidcCallback.tsx` + `App.tsx` short-circuit (non-hash redirect path).
-- Session/refresh: `state/sessions.ts` OIDC fields, `client/{oidcTokenRefresher,oidcLogout}.ts`, `initMatrix.ts` wiring.
-- Account mgmt: `settings/account/OidcManageAccount.tsx`.
-- 13 unit tests (discovery/flow/session/cache/callback parsing). All gates green.
-  **Awaiting verification (needs a real MSC3861 server — lotusguild is NOT one):** deploy + log into **mozilla.org** (requires adding mozilla to the deployed `config.json` homeserverList + its domains to the CSP `connect-src`/`img-src` — see below), OR run a local `matrix-authentication-service` + Synapse `msc3861` dev loop.  
-  **Mozilla.org test enablement: ALREADY DEPLOYED (verified 2026-07)** — `matrix/cinny/config.json` homeserverList includes `mozilla.org` and the nginx CSP `connect-src` includes the mozilla/modular/vector domains (`matrix/cinny/nginx.conf:42`). **Nothing blocks the test — just pick mozilla.org on the login screen and complete an OIDC login.**

-## Priority 5 — Gamer / Aesthetic / Customization
-
-### [MOVED] P5-9 · LFG (Looking for Group) Command → LotusBot
-
-**Decision:** Implemented as `!lfg` in LotusBot rather than a client slash command. Bot-side rendering works consistently across all Matrix clients; client-side enhanced cards would only be visible to Lotus Chat users and require sanitizer auditing. The bot can also support richer flows (list active LFGs, DM interested players, auto-expire posts).
-

-
-### [~] P5-15 · In-Call Soundboard — IMPLEMENTED (⚠️ awaiting live verification, D2-7)
-
-**What:** Soundboard button in the call controls bar → popout grid of the user's clips; clicking one plays it **into the call** as a real published track (peers hear it) and locally (presser hears it). Clips are **user-uploadable, just like custom emojis/stickers**.  
-**🔱 [EC-FORK] Fork side + cinny side DONE.** The fork ships `io.lotus.inject_audio` (`LotusWidgetActions.InjectAudio`, allow-listed in `widget.ts`), armed via the `lotusAudioInject=1` flag; it publishes a clip as a separate LiveKit track — a **real** in-call soundboard mixed into the call, not local-only. cinny now drives it.  
-**Shipped (cinny):**
-
-- Clips stored in `io.lotus.soundboard` account data → **synced across devices like emoji/sticker packs** (`useSoundboard` hook; `AccountDataEvent.LotusSoundboard`).
-- Upload audio (≤1 MB, ≤40 clips) → `mx.uploadContent` → mxc; play resolves mxc → authed download → `blob:` object URL (the widget can't fetch authenticated media itself) → `control.injectAudio(url, volume)` + local playback.
-- `CallSoundboard.tsx` popout in the call bar (upload / play / delete), gated on the `soundboardEnabled` setting (Settings → General → Calls, + volume slider).  
-  **Remaining:** a dedicated Settings management page (optional — upload/delete already live in the popout); a small default clip set; live verification (D2-7). Files: `utils/soundboardClips.ts`, `hooks/useSoundboard.ts`, `features/call/CallSoundboard.tsx`, `plugins/call/CallControl.ts#injectAudio`.  
-  **Complexity:** Medium — done.

-### [~] P5-20 · Quick Reply from Browser Notification
-
-**What:** Inline reply field in browser notification toasts via Notification Actions API. Reply sends as threaded reply to the triggering message.  
-**[AUDIT REQUIRED]** (1) Verify browser Notification Actions API support in target browsers. (2) Confirmed: service worker EXISTS at `src/sw.ts` — add `notificationclick` handler there.  
-**Complexity:** Medium-High.  
-**Partial Fix Applied ⚠️ UNTESTED:** Notifications now (a) show the real message body (`username: message` instead of "New inbox notification from..."), (b) click navigates directly to the room at the specific event (not the inbox), (c) `window.focus()` called on click so the tab comes to front, (d) reminder toasts also link to the specific event. Full inline-reply via Notification Actions API still needs the SW `push`+`notificationclick` pipeline (requires switching from `new Notification()` to `showNotification()` through the SW).

-### [x] P5-30 · Advanced ML Noise Suppression (Krisp-style)
-
-**What:** High-end background noise cancellation using a pre-trained ML model (RNNoise) running in the browser. Removes dogs, fans, and keyboard clicks from the mic stream.  
-**Shipped:** 3-tier setting (Off / Browser-native / ML) in Settings → General → Calls.  
-**🔱 [EC-FORK] DONE — moved in-source (2026-06).** ML denoise is now a first-class audio stage **inside** the forked Element Call: a LiveKit `TrackProcessor<Audio>` activated by `lotusDenoiseSource=1` (cinny sets it when ML is selected). The old build-time `getUserMedia`/`index.html` monkeypatch is **removed**. Because EC re-runs the processor on every (re)publish, denoise now **survives reconnects and mic-device switches** — this is the A7 fix (see `LOTUS_BUGS.md` A7, `LOTUS_TESTING.md` §D2-1). The processor degrades to the raw mic rather than going silent.  
-**Key decision:** LiveKit's Krisp filter is LiveKit-Cloud-only (we self-host the SFU); EC's own RNNoise PR #3892 is unmerged. Owning the fork let us implement the in-source stage directly.
-
-**Models — all in-source in the fork:**
-
-- [x] **DeepFilterNet 3** (48 kHz, **ML default**) · **DTLN** (16 kHz) · **RNNoise** (48 kHz) · **Speex** (48 kHz) — all four wired and selectable; dropdown ordered best-quality first. Tier default is **Browser-native**.
-- [x] **Quality tuning (2026-07):** dry/wet **attenuation floor** (~-16 dB, RNNoise/Speex only — the "robotic" fix; DTLN/DFN would comb-filter), **gate-after-ML**, **DFN level 80→60**. Floor tunable via `lotusDenoiseFloor`.
-- [x] **AEC/AGC (2026-07):** echo-cancellation ON; **AGC OFF for the ML tier** (`autoGainControl=false`, threaded through EC `UrlParams`→`ConnectionFactory`) so browser AGC doesn't fight the model; playback confirmed no AEC-defeat.
-- [x] **Reliability (2026-07):** never-silent watchdog, resume-timeout, WASM-cache reject-eviction, activate-off-local-participant, init/build leak fixes.
-- [ ] **Open verification:** real-call by-ear **A/B** — model choice, floor value, AGC on/off (RNNoise known-weak historically). `LOTUS_TESTING.md` §D2-1 / J2.
-- [ ] **GTCRN (RESEARCHED — DEFERRED):** tiny MIT 16 kHz model that beats RNNoise, but **no drop-in browser package** — needs a ~1-week from-scratch build: `onnxruntime-web` (WASM, 1 thread) in a **Web Worker** (ORT can't run in an AudioWorklet — issue #13072) behind a custom AudioWorklet ring-buffer node presenting as an `AudioNode`; model `gtcrn_simple.onnx` (~300 KB, stateful — thread `conv/tra/inter` caches per frame); we write STFT/iSTFT (n_fft 512/hop 256). Assets ~3–4 MB via the `lotusDenoise()` vite plugin. Registration checklist known (both repos, incl. the 2nd `denoisePipeline.ts` used by the DenoiseTester). **Revisit only if low-power quality is insufficient after validating the current tuning.**
-- [ ] **Desktop-only / HW-gated (future):** FRCRN or NVIDIA Maxine (RTX/Tensor only) — impossible in-browser; would run in the Tauri Rust backend + bridge a virtual mic into the webview. Detect capability; web falls back to RNNoise.
-- **Excluded:** Krisp (LiveKit Cloud only); FRCRN/Maxine on web (GPU/server-bound).

-
-### [~] P5-31 · Granular Voice & Screenshare Quality Controls — IMPLEMENTED (⚠️ awaiting live verification, D2-8)
-
-**What:** Let users (and room admins) adjust audio bitrate and screenshare bitrate/framerate.  
-**🔱 [EC-FORK] Fork side + client side DONE.** The fork ships `io.lotus.set_quality` (`LotusWidgetActions.SetQuality`) that applies audio/screenshare encoding params (`RTCRtpSender.setParameters`, all simulcast encodings, re-applied on `TrackUnmuted`/republish) inside EC. cinny now drives it.
-
-**Shipped (cinny):**
-
-1. **User settings** (Settings → General → Calls): Microphone Bitrate, Screenshare Bitrate, Screenshare Framerate (`callAudioBitrate` / `screenshareBitrate` / `screenshareFramerate`).
-2. **Room-admin caps**: `io.lotus.room_quality` state event (`StateEvent.LotusRoomQuality`) + `RoomQuality.tsx` in Room Settings → General → Voice (mirrors `RoomVoiceLimit`).
-3. **Apply logic**: `useCallQuality` (wired in `CallEmbedProvider`'s `CallUtils`) builds `min(user setting, room cap)` and sends `io.lotus.set_quality` on join / when settings change (`utils/callQuality.ts`, unit-tested).
-
-**Server-side enforcement (DONE — matrix repo):** extended `voice-limit-guard.py` (LXC 151) to also read `io.lotus.room_quality` and hard-enforce a **publish-source policy** for ALL clients.
-
-- **Reality (researched, primary-source, LiveKit 1.9.11):** numeric bitrate/fps caps **cannot** be hard-enforced server-side — LiveKit is a pure SFU (forwards, never transcodes); there is NO bitrate/fps field in the JWT grant, `RoomConfiguration`, server `limit:` config, or any admin RPC, and stock Element Call ignores room metadata / custom claims for publish quality. So numeric caps stay **cooperative** (our fork honors them via `min()` → `set_quality`, already shipped).
-- **What IS hard-enforced cross-client:** `VideoGrant.canPublishSources`. The guard holds the LiveKit secret, so when `io.lotus.room_quality` sets `allow_screenshare:false` / `allow_camera:false` it re-signs the issued JWT with a narrowed source list → the SFU refuses those tracks for **every** client (Element, FluffyChat, our fork). Mic always kept. Fail-open; unit-tested (`livekit/test_voice_limit_guard.py`). Admin UI: Room Settings → Voice → **Call Permissions** switches. cinny also hides the blocked buttons.
-- **Live (mid-call) enforcement — DONE:** the JWT re-sign covers new joins; for participants **already in the call**, a background reconcile loop in the guard calls LiveKit `UpdateParticipant` every ~3 s to narrow `canPublishSources`, which unpublishes an in-progress screenshare/camera **server-side for all clients** and blocks re-publish (verified LiveKit 1.9.11 auto-unpublishes on permission narrowing). Only removes forbidden sources (never grants), preserves other permission flags, no-ops once compliant. So flipping a room audio-only kills live cameras/screenshares within ~one interval.
-- **Not enforceable / deferred:** numeric server enforcement (impossible — see above); screenshare **resolution** control (`set_quality` covers bitrate + framerate; resolution needs a `getDisplayMedia` hook inside the fork).
-
-**Complexity:** DONE — client (cooperative numeric caps) + server (hard publish-source policy). Only the physically-impossible numeric server enforcement is out of scope.

-### [~] P5-35 · Desktop — Notification Click Opens Room — IMPLEMENTED (Tier B, via the P5-41 WinRT toast: click → open room, reply → send); native CI-compile-pending, runtime-verify on Windows
-
-**What:** Clicking a system tray notification navigates to the relevant room. Quick-reply from the notification toast would send the reply without opening the window.  
-**Status:** Deferred (Tier B). Note: the "can't compile-test without a Windows build environment" premise is **outdated** — CI now compiles Windows (Gitea self-hosted `windows` runner + GitHub `windows-latest`), and `windows`-crate/COM code already ships (e.g. `set_badge_count`, and the Tier A jump list). This still depends on P5-41 (the WinRT toast + custom activator), so it rides with that; it was not part of the Tier A wave.  
-**Note:** Tray icon and `matrix:` deep links already bring the window forward on most interactions. Revisit when tauri-plugin-notification gains click handler support upstream.  
-**Complexity:** High (platform-specific native code required).
-
----
-
-### [~] P5-36 · Desktop — Windows Jump List — IMPLEMENTED (Tier A); native CI-compile-pending, runtime-verify on Windows
-
-**What:** Right-clicking the taskbar icon shows a jump list with recent/favorite rooms for quick navigation.  
-**Status:** Deferred — implementing the Windows COM jump list API in Tauri requires iterating on C++/COM code that can only be compile-checked on Windows, making blind CI iteration impractical.  
-**Action when unblocked:** Revisit when a Tauri plugin abstracts the Windows Shell `ICustomDestinationList` interface, or when a Windows build environment is available for local iteration.  
-**Complexity:** High (Windows-only native COM).
-
----
-
-### [~] P5-41 · Desktop — Native WinRT Toast Notifications — IMPLEMENTED (Tier B; ToastNotification + reply input + in-process Activated; falls back to tauri-plugin-notification); native CI-compile-pending. Runtime needs a Start-menu shortcut + matching AppUserModelID to surface
-
-**What:** Replace emulated notifications with native WinRT Toast notifications.  
-**Approach:** Implement native WinRT Toast integration using `windows-rs` to enable full Action Center integration, including native Quick Reply functionality.
-
-### [~] P5-42 · Desktop — Persistent Background Sync — IMPLEMENTED (Batch 3, pragmatic keep-alive); native CI-compile-pending, runtime-verify on Windows
-
-**What:** Keep receiving messages/notifications instantly while the app is closed to the tray.  
-**Shipped approach (80/20):** rather than a multi-sprint headless Rust sync client, disable Chromium background throttling via WebView2 `additional_browser_args` (`--disable-background-timer-throttling --disable-renderer-backgrounding --disable-backgrounding-occluded-windows`, added to the existing Tauri default args) so the existing JS Matrix `/sync` loop keeps running full-speed in the tray. Windows/WebView2 only; does not block system sleep. See `cinny-desktop/src-tauri/src/lib.rs` (WebviewWindowBuilder).  
-**Deferred (not needed):** the full headless Rust sidecar — only revisit if WebView2 ever hard-suspends despite these flags (would require a second Matrix client with its own /sync + push-rule eval + E2EE-aware notification content).
-
-### [~] P5-43 · Desktop — System Media Transport Controls (SMTC) — IMPLEMENTED (Tier A); CI-compile-pending; SMTC may need an active media/audio session to surface — verify on Windows
-
-**What:** Integrate with Windows SMTC for volume flyout call/media control.  
-**Approach:** Use Windows SMTC API to expose call status, mic mute/unmute, and media controls to the Windows volume flyout/media overlay.
-
-### [~] P5-44 · Desktop — Taskbar Thumbnail Toolbar — IMPLEMENTED (Tier A); native CI-compile-pending, runtime-verify on Windows
-
-**What:** Add persistent call controls to the taskbar preview.  
-**Approach:** Implement a COM thumbnail toolbar in the application preview window, featuring Mute/Deafen/End Call buttons.
-
-### [~] P5-46 · Desktop — System Power Management (Call Continuity) — IMPLEMENTED (Tier A reference); web verified; native CI-compile-pending (Windows only; macOS/Linux no-op TODO)
-
-**What:** Prevent system sleep/hibernate during active calls.  
-**Approach:** Use Tauri/Rust `power-manager` or platform-specific APIs to block system power saving states while a voice/video session is active.
-
-### [~] P5-47 · Desktop — TDS-Styled Native Window Chrome — IMPLEMENTED (Tier A, OPT-IN/default-off, runtime-reversible); web verified; native CI-compile-pending
-
-**What:** Replace system titlebar with custom Lotus TDS chrome.  
-**Approach:** Configure Tauri window (`decorations: false`) and implement custom, TDS-token compliant titlebar controls (Close/Max/Min) for a cohesive UI.
-
-### [~] P5-48 · Desktop — Native File System Drag-and-Drop Improvements — IMPLEMENTED (recursive folder upload, web-verified: tsc/build/tests). SCOPED-OUT: `.lnk` shortcut resolution (webview never exposes a dropped file's OS path → native can't resolve the target) and "Send To" (installer/registry shell integration) — deferred
-
-**What:** Enhance drag-and-drop support for Windows.  
-**Approach:** Improve handling for Windows file shortcuts, recursive folder uploads, and shell-integrated "Send To" context menu actions.
-
-### [~] P5-49 · Desktop — Network Awareness (NCSI Integration) — IMPLEMENTED (Tier A; INetworkListManager poll → mx.retryImmediately); native CI-compile-pending, runtime-verify on Windows
-
-**What:** Proactively detect Windows network connectivity changes.  
-**Approach:** Integrate with the Windows Network Connectivity Status Indicator (NCSI) API to improve offline mode transition latency and network recovery.
-
-### [WON'T FIX] P5-50 · Desktop — Windows Hardware-Accelerated Media Pipeline
-
-**What:** Replace standard browser decoding with native Windows Media Foundation.  
-**Why won't-fix (researched):** WebRTC media (the call pipeline) lives entirely inside WebView2/Chromium — you cannot inject Media Foundation/DirectShow into WebRTC's decode path from the Tauri host. Chromium already uses the platform's hardware decoders (D3D11VA/MF) where the GPU supports the codec, so there is no separate CPU pipeline to offload. Not actionable as described.
-
-### [DEFERRED] P5-51 · Desktop — Federated "Identity Contexts" (Isolation Manager)
-
-**What:** Compartmentalize sessions, local databases, and caches into isolated "Contexts" (e.g. Work vs. Personal) with a zero-leak boundary.  
-**Decision:** Deferred (reviewed 2026-07). Multi-sprint, and it touches the auth/crypto/storage core — not worth the risk/effort for a niche need right now. Kept here with a concrete spec so it's actionable later.
-
-**Future-work spec (why it's big):** the app is currently **single-session**.
-- Session lives in `src/app/state/sessions.ts` under fixed localStorage keys — `cinny_access_token`, `cinny_device_id`, `cinny_user_id`, `cinny_hs_base_url`, plus the OIDC keys (`cinny_refresh_token`, `cinny_expires_at`, `cinny_oidc_*`).
-- Persistence lives in `src/client/initMatrix.ts`: two fixed IndexedDB stores — `web-sync-store` (`IndexedDBStore`) and `crypto-store` (`IndexedDBCryptoStore`) — feeding one `createClient(...)`.
-
-True per-context isolation would require: (1) namespace every localStorage key per context (`ctx:<id>:cinny_*`); (2) per-context IndexedDB dbNames for **both** the sync store and the crypto store; (3) a context registry + switcher UI (create/rename/delete/switch); (4) full client teardown + re-init on switch (`initMatrix` currently assumes one global client); (5) per-context settings + notification/quiet-hours state; (6) careful crypto-store isolation so device keys never bleed across contexts. **Smaller intermediate step** if demand appears: plain multi-account (fast account switch) *without* the hard isolation boundary — much less risky, reuses most of the login flow.  
-**Priority:** Extreme Low (Multi-sprint/Architectural).
-
-### [DROPPED] P5-52 · Desktop — Room-Level Sync Governor (Performance Control)
-
-**What:** Granular per-room sync tuning (frequency, event-type filtering).  
-**Why dropped (reviewed 2026-07):** matrix-js-sdk can't do **true** per-room sync filtering — all room events still come down the single `/sync` stream, so "disable typing/receipts in heavy rooms" can only be a **cosmetic client-side hide**, not an actual performance/bandwidth win. That, plus the UX-complexity risk flagged originally, makes it not worth building. If per-room quieting is ever wanted, add a simple "mute typing & receipts in this room" toggle to normal room settings — not a "governor."
-
-### [DEFERRED] P5-53 · Desktop — Local-Only "Scripting" Plugin System (Tampermonkey-like)
-
-**What:** A sandboxed environment for local execution of user scripts on Matrix events.  
-**Decision:** Deferred (reviewed 2026-07). A full WASM execution engine + script registry + management UI + security model is a large surface for a very small (power-user) audience.  
-**Recommended lighter alternative (the ~80/20) if we ever want event automation:** a built-in **automation-rules** feature — declarative "when an incoming event matches X (room / sender / keyword / type) → notify / play sound / highlight / auto-react" rules, configured in Settings. Covers the realistic use cases (custom alerts, keyword pings) with **no arbitrary code execution**, so no sandbox/security burden. Build that instead of a scripting engine if the need arises.
-
-### [~] P5-55 · Desktop — Composer Toolbar Drag-and-Drop Reordering — IMPLEMENTED (Tier A); web-verified (tsc/build/tests). Awaiting live UX check
-
-**What:** Allow users to reorder toolbar icons via drag-and-drop.  
-**Approach:** Extend the current settings-based toolbar toggle system to include a drag-and-drop UI mode in the composer settings, allowing users to personalize their icon order.
-
-### [~] P5-56 · Desktop — Windows "Focus Assist" (DND) Sync — IMPLEMENTED (Tier B; SHQueryUserNotificationState poll → suppresses notifications+sounds via the quiet-hours gate); native CI-compile-pending, runtime-verify on Windows
-
-**What:** Automatically toggle notification state based on Windows Focus Assist.  
-**Approach:** Integrate with the Windows `NotificationCenter` / `Focus` state via Tauri/Rust to automatically enable/disable Lotus Chat's internal notification suppression mode when Windows Focus Assist is toggled.

-## 🚀 Features to Add
-
-- [ ] **Mobile Audit:** Comprehensive audit of all features in LOTUS_FEATURES.md for mobile PWA usability and layout responsiveness.
-
----
-
-## Blocked Features
-
-These features are confirmed desirable but cannot be built until the listed dependency is resolved.
-Check back after each Synapse upgrade — re-run `/matrix/client/versions` and `unstable_features` to see if they've become available.
-
-### [BLOCKED] · Live Location Sharing (MSC3489 + MSC3672)
-
-**Blocked by:** `org.matrix.msc3489 = false` AND `org.matrix.msc3672 = false` on `matrix.lotusguild.org` (confirmed from unstable_features).  
-**What it would do:** Real-time GPS beacon streaming upgrading the existing static location share.  
-**Action when unblocked:** Both MSCs must be enabled on the homeserver before any client work.
-
-### [BLOCKED] · Reaction / Relation Redaction (MSC3892)
-
-**Blocked by:** `org.matrix.msc3892` = false on `matrix.lotusguild.org`  
-**What it would do:** Cleanly remove a reaction without redacting the parent message.  
-**Current behavior:** Full event redaction — acceptable fallback, no user-facing issue.  
-**Action when unblocked:** Find `onReactionToggle` redaction call site; swap in MSC3892 endpoint with fallback.
-
-### [BLOCKED] · Room Preview Before Joining (MSC3266)
-
-**Blocked by:** `GET /_matrix/client/v1/rooms/{roomId}/summary` returns `M_UNRECOGNIZED` 404 — endpoint not implemented in Synapse 1.155. Config flag `msc3266_enabled: true` is set but has no effect; Synapse appears not to have shipped a stable implementation at the v1 path. Verified 2026-06-18.  
-**What it would do:** Show room name, topic, avatar, member count before joining.  
-**Action when unblocked:** Re-test after each future Synapse upgrade.
-
-### [BLOCKED] · Thread Subscriptions (MSC4306)
-
-**Blocked by:** `org.matrix.msc4306` = false on `matrix.lotusguild.org`  
-**What it would do:** Follow a thread without posting; get notifications for replies.  
-**Action when unblocked:** Add "Follow thread" button in the thread panel header (depends on #P3-8 Thread Panel).
-
-### [DONE] · Report User (MSC4260) ✅
-
-**Previously blocked by:** Server spec v1.12, but `POST /_matrix/client/v3/users/{userId}/report` was confirmed **200** on 2026-06-18 (live since Synapse 1.133.0).  
-**What it does:** Reports a specific user to homeserver admins (separate from reporting a message).  
-**Note:** Report Message already exists in upstream Cinny. This adds Report User to the profile panel.  
-**Implemented 2026-06-18:** `ReportUserModal.tsx` added at `src/app/features/room/ReportUserModal.tsx`. Button wired into `UserRoomProfile.tsx` between UserModeration and UserDeviceSessions (hidden for own profile). Category dropdown + reason text, inline success/error feedback, auto-close 1500ms after success.

-**Finding:** [MSC4427 — Custom banners for user profiles](https://github.com/matrix-org/matrix-spec-proposals/pull/4427) defines a `banner_url` profile field on top of the MSC4133 extensible-profile system (which our server supports, `uk.tcpip.msc4133.stable = true`, and which became stable in Matrix v1.16). However MSC4427 is an **open proposal, not merged** — no cross-client standard yet, so per this item's own rule: do not implement. **Revisit when MSC4427 merges** (implementation would then be small: read/write the field via the MSC4133 profile API + render a banner in UserHero/profile popouts).

-### P3-8 · Thread Panel (Full Side Drawer) — 🟢 FULL DESIGN (2026-07, ready to execute)
-
-**Decisions (each backed by SDK evidence in node_modules/matrix-js-sdk):**
-
-| Question | Decision |
-|---|---|
-| Thread rendering | **New lean `ThreadTimeline`** reusing `Message`, `useVirtualPaginator`, and RoomTimeline's exported timeline helpers (lines 156-227). Do NOT refactor 2214-line RoomTimeline (its ~35 hooks are hardwired to the room live timeline). |
-| threadSupport | **Enable `threadSupport: true`** in `initMatrix.ts` (~line 39). ⚠️ Thread replies then LEAVE the main timeline (`room.js eventShouldLiveIn` → `shouldLiveInRoom:false`), retroactively on reload — MUST ship the "N replies" summary chip in the same release. Roots stay in both timelines. |
-| State | `roomIdToActiveThreadIdAtomFamily` (per-room, mirrors `roomIdToReplyDraftAtomFamily`) in new `state/room/thread.ts` + `getThreadDraftKey(roomId, threadRootId)` = `` `${roomId}::${threadRootId}` `` |
-| Composer | **Reuse RoomInput**: add optional `threadRootId` prop; scope its 3 atom-family lookups by draftKey (isolates thread drafts from the main composer); pass `threadRootId ?? null` at all 7 `mx.sendMessage/sendEvent` call sites — the SDK's `addThreadRelationIfNeeded` then emits spec-correct `m.thread` relations incl. reply-in-thread. Separate `useEditor()` instance in the panel. Hide schedule + commands in thread mode v1. |
-| Unreads | v1 = unread badge on the summary chip (`room.getThreadUnreadNotificationCount` — counts already synced independent of threadSupport) + `markThreadAsRead` threaded receipt when panel open at bottom. |
-| Mobile | Pure CSS like `MembersDrawer.css.ts`: fixed width toRem(360) desktop, `position:fixed; inset:0` under 750px. |
-
-**Critical side-effect fixes (one-liners, land FIRST):**
-1. `initMatrix.ts` → `threadSupport: true`.
-2. `utils/notifications.ts:24` → `sendReadReceipt(latestEvent, type, /*unthreaded*/ true)` — otherwise markAsRead becomes `main`-scoped and room badges stick permanently unread (room unread total includes thread counts).
-
-**Known SDK traps (verified):**
-- **Local echo gap:** chronological pending ordering means the thread timelineSet never receives pending events (`canContain` rejects; `room.getPendingEvents()` THROWS in this mode) — ThreadTimeline must render its own pending strip via `RoomEvent.LocalEchoUpdated` filtering on `threadRootId`, deduped against `thread.findEventById`.
-- **Bootstrap:** `room.getThread(id) ?? room.createThread(id, room.findEventById(id), [], false)` — the SDK auto-fetches via `/relations` and inserts the root at top; gate rendering on `thread.initialEventsFetched`; decrypt with `decryptAllTimelineEvent` after init + each pagination.
-- **Deep links:** `getEventTimeline(mainSet, threadEventId)` returns undefined for thread events — redirect jump-to-event to the panel (best-effort v1).
-- **Summary chip** must render from the server-aggregated bundle (`unsigned['m.relations']['m.thread']`) so it works before any Thread object exists.
-- Room-list "latest message" preview may show the root, not the newest reply — cosmetic, accept v1.
-
-**File inventory — new:** `state/room/thread.ts` (+test), `features/room/thread/{useThread.ts, threadSummary.ts(+test), ThreadTimeline.tsx(+css), ThreadPanel.tsx(+css), ThreadSummary.tsx, index.ts}`, `hooks/useThreadSummary.ts`. **Edited:** `initMatrix.ts` + `utils/notifications.ts` (coordinator, step 0), `RoomInput.tsx` (threadRootId prop), `RoomTimeline.tsx` (handleReplyClick startThread → open panel; ThreadSummary chips at the two Message call sites; Reply onThreadClick; deep-link redirect), `components/message/Reply.tsx`, `Room.tsx` (render panel after MediaGallery block, gated `!callView && activeThreadId`, `key={roomId+threadId}`).
-
-**4-agent partition:** step 0 (coordinator one-liners) → A: state+SDK glue (+tests) · B: ThreadTimeline (largest; copies the `useTimelinePagination` pattern rather than exporting it) · C: RoomInput changes · D: panel shell + RoomTimeline/Reply integration — all parallel against pinned interface contracts → coordinator wires Room.tsx + gates.
-
-**Verification:** gates (tsc/eslint/build/tests) + post-merge manual QA: open thread via chip/menu/indicator; pending→confirmed echo; `is_falling_back:false` on reply-in-thread; main timeline shows root+chip only; badge clears; reload keeps partitioning; encrypted threads decrypt. **Release note required:** threaded replies no longer render inline in the main timeline.

-### P4-4 · Math / LaTeX Rendering
-
-**Mechanism:** KaTeX injection into the HTML parser.
-
-- **Sanitizer (`src/app/utils/sanitize.ts`):** Allow KaTeX-specific tags and classes (e.g., `span`, `annotation`, `math`). Use a specialized allowed list for math blocks.
-  > [Gemini_Found] `sanitize.ts` uses **`sanitize-html`** (not DOMPurify) with an explicit allowlist (`allowedTags`) and `disallowedTagsMode: 'discard'`. All MathML tags are currently absent from the allowlist and are silently stripped. Update `permittedHtmlTags` to include: `<math>`, `<mi>`, `<mo>`, `<mn>`, `<ms>`, `<mtext>`, `<mspace>`, `<mrow>`, `<mfrac>`, `<msqrt>`, `<mroot>`, `<mstyle>`, `<merror>`, `<mpadded>`, `<mphantom>`, `<mfenced>`, `<menclose>`, `<msub>`, `<msup>`, `<msubsup>`, `<munder>`, `<mover>`, `<munderover>`, `<mmultiscripts>`, `<mtable>`, `<mtr>`, `<mtd>`, `<maligngroup>`, `<malignmark>`, and `annotation`. Also add the required MathML attributes (e.g. `xmlns`, `display`, `mathvariant`) to `permittedTagToAttributes`.
-- **Parser (`src/app/plugins/react-custom-html-parser.tsx`):** Detect `$ ... $` and `$$ ... $$` patterns in text nodes:
-  ```tsx
-  if (node.type === 'text') {
-    const parts = node.data.split(/(\$\$.*?\$\$|\$.*?\$)/g);
-    return parts.map((p) => {
-      if (p.startsWith('$')) return <KaTeX math={p.replace(/\$/g, '')} />;
-      return p;
-    });
-  }
-  ```
-- **CSS (`src/app/styles/CustomHtml.css.ts`):** Import `katex/dist/katex.min.css` only when a math block is rendered to save initial bundle size.
-
----
-
-### P4-6 · OIDC / SSO Next-Gen Auth (MSC3861)
-
-**Mechanism:** Matrix Authentication Service (MAS) Integration.
-
-- **Architecture:** Shift from password-based `/login` to OAuth2 `authorization_code` flow.
-- **Key Files:** `src/app/pages/auth/Login.tsx` and `src/app/hooks/useAuth.ts`.
-- **Implementation:** Use `oidc-client-ts` or a similar lightweight OIDC library. Check for `m.authentication` in `/.well-known/matrix/client`. Redirect to the MAS authorization endpoint. Handle the callback in a new `OidcCallback` route and store the OIDC `refresh_token`.
-
----
-
-### P5-1 · Custom Accent Color Picker (Non-TDS only)
-
-**Mechanism:** Dynamic CSS variable injection.
-
-- **Setting (`src/app/state/settings.ts`):** Add `customAccentColor: string` (hex).
-- **Manager (`src/app/pages/ThemeManager.tsx`):** Inside the `useEffect` that monitors theme changes:
-  ```typescript
-  if (!lotusTerminal && customAccentColor) {
-    document.documentElement.style.setProperty('--lt-accent-orange', customAccentColor);
-    document.documentElement.style.setProperty('--lt-accent-orange-glow', `${customAccentColor}80`);
-  }
-  ```
-- **UI (`src/app/features/settings/general/General.tsx`):** Use `<Input type="color">`. Hide this section if `lotusTerminal` is `true`.
-
----
-
-### P5-15 · In-Call Soundboard
-
-**Mechanism:** Local-to-Global Audio Bridge via Web Audio API.
-
-- Create an `AudioContext` and a `MediaStreamDestinationNode`.
-- Create an `AudioBufferSourceNode` for each clip.
-- Route the mic `MediaStream` and the clip source to the destination node.
-- Pass the destination's `.stream` to the call bridge.
-
-> ⚠️ **[Gemini_Found — CORRECTED]** Gemini originally suggested using LiveKit's `LocalAudioTrack.replaceTrack()` to mix audio into the call stream. This is **not possible** from Lotus Chat's realm: Element Call runs in a **cross-origin iframe** controlled via `matrix-widget-api` (postMessage). LiveKit's JS SDK and its `LocalAudioTrack` live inside EC's sandboxed context — inaccessible from our code. This directly contradicts the confirmed constraint already listed in the Server Capabilities table: _"Cindy CANNOT inject audio into EC call stream — In-call soundboard must be redesigned as local-only."_ The soundboard must be a local-playback-only feature (output through the user's speakers, not mixed into the call audio stream).
->
-> 🔱 **[EC-FORK — RESOLVED]** Both the original claim and the earlier "practical blocker still holds" correction are now **outdated**. EC is same-origin **and** we own the source, so we no longer reach into EC's module scope from cinny — instead the fork **exposes the inject point itself**: the `io.lotus.inject_audio` widget action (`LotusWidgetActions.InjectAudio`) publishes a clip as a separate LiveKit track from inside EC. A **real** in-call soundboard (mixed into the call, not local-only) is therefore unblocked, and the cinny-side soundboard UI is now **built** (P5-15 above): uploadable clips played into the call via this action, stored in `io.lotus.soundboard` account data.

-
-### P5-20 · Quick Reply from Browser Notification
-
-**Mechanism:** Service Worker `notificationclick` Action.
-
-> [Gemini_Found] Implementation detail: `serviceWorkerRegistration.showNotification()` should be used instead of `new Notification()` so that the service worker can listen to the `notificationclick` event. `new Notification()` creates notifications that are bound to the client page, not the SW.
-
-```typescript
-// src/sw.ts
-self.addEventListener('notificationclick', (event) => {
-  if (event.action === 'reply' && event.reply) {
-    const { roomId, threadId } = event.notification.data;
-    const session = sessions.get(event.clientId);
-    fetch(`${session.baseUrl}/_matrix/client/v3/rooms/${roomId}/send/m.room.message`, {
-      method: 'POST',
-      headers: { Authorization: `Bearer ${session.accessToken}` },
-      body: JSON.stringify({
-        msgtype: 'm.text',
-        body: event.reply,
-        'm.relates_to': threadId ? { rel_type: 'm.thread', event_id: threadId } : undefined,
-      }),
-    });
-  }
-});

-### P5-30 · Advanced ML Noise Suppression — Model Roadmap
-
-See shipped implementation in LOTUS_FEATURES.md → "Noise Suppression (Advanced Multi-Tier)".
-
-**Models status:**
-
-- **RNNoise** (sapphi, 48 kHz) — ✅ working, default fallback. Keep — runs on any hardware.
-- **Speex** (sapphi, 48 kHz) — ✅ working, low value; candidate to drop.
-- **DTLN** (@workadventure, 16 kHz) — 🟡 wired; sample-rate fix applied (was robotic at 48 kHz). **TODO: verify in a real call.** Narrowband (16 kHz) = slightly telephone-y even when correct.
-
-**Constraints:** client-side AudioWorklet, fully self-hosted, no GPU, self-hosted SFU (no LiveKit Cloud).
-
-**Roadmap:**
-
-- [ ] Verify DTLN 16 kHz fix in a real call.
-- [ ] **DeepFilterNet 3** — best self-hostable upgrade: Rust→WASM, CPU real-time, 48 kHz fullband. Self-host `df_bg.wasm` + DFN3 ONNX model; wire a 48 kHz worklet. Audio quality unverifiable without a real-call test.
-- [ ] **Desktop-only / HW-gated:** FRCRN (Alibaba) or NVIDIA Maxine (RTX/Tensor only). Runs in Tauri Rust backend + bridges a virtual mic into the webview. Must detect capability; web + weak HW falls back to RNNoise/DTLN.
-
----
-
-### P5-31 · Granular Voice & Screenshare Quality Controls
-
-**Mechanism:** WebRTC Encoding Parameters + Backend Quality Guard.
-
-- **State Event:** `io.lotus.room_quality` (state key `""`) containing:
-  ```json
-  { "audio_bitrate": 128000, "screen_max_res": "1080p", "screen_max_fps": 60 }
-  ```
-- **Screenshare:** In `src/app/plugins/call/CallControl.ts`, map the "Quality" setting to `getDisplayMedia` constraints.
-- **Audio Bitrate:** After the call joins, find the `RTCRtpSender` for the audio track:
-  ```typescript
-  const sender = peerConnection.getSenders().find((s) => s.track?.kind === 'audio');
-  const params = sender.getParameters();
-  params.encodings[0].maxBitrate = roomBitrate || 128000;
-  await sender.setParameters(params);
-  ```
-- **Backend Sidecar:** Extend `voice-limit-guard.py` (LXC 151) to fetch `io.lotus.room_quality` and inject limits into the LiveKit JWT or return them as an authorized config packet.

-### [x] P5-40 · Desktop — Proactive Update Notifications (Tauri) — DONE (already shipped: `TauriUpdateFeature` in ClientNonUIFeatures.tsx polls every 12h + fires the sticky update toast)
-
-**Key Files:** `src/app/hooks/useTauriUpdater.ts`, `src/app/pages/client/ClientNonUIFeatures.tsx`, `src/app/features/toast/LotusToastContainer.tsx`.
-
-1. Create a `TauriUpdateFeature` component. Use `useTauriUpdater()` to get the `check` function and `status`.
-2. In a `useEffect`, call `check()` on mount and then on a `setInterval` (every 12 hours).
-3. When status transitions to `{ state: 'available', version: '...' }`, fire a Lotus Toast: "Lotus Chat v[version] is available!" with an "Update" button that calls `install()`.
-4. Store `lastCheck` timestamp in `localStorage` to prevent redundant checks on refresh.
-
----
-
-### Mobile Bookmarks Visibility Fix
-
-**Issue:** `ClientLayout.tsx` explicitly restricts `BookmarksPanel` to `ScreenSize.Desktop` (lines 51-56).
-
-```tsx
-// ClientLayout.tsx
-{
-  bookmarksOpen && (
-    <BookmarksPanel
-      onClose={() => setBookmarksOpen(false)}
-      isMobile={screenSize !== ScreenSize.Desktop}
-    />
-  );
-}
-```
-
-`BookmarksPanel.tsx` already supports the `isMobile` prop (line 127) to enable full-screen absolute positioning. No other changes required.
-
----
-
-### Remind Me Later (Slack-style)
-
-**Mechanism:** Account Data + Timer/Service Worker.
-
-- **Storage (`src/app/hooks/useReminders.ts`):** Store in account data `io.lotus.reminders` as `Array<{ id: string, roomId: string, eventId: string, timestamp: number }>`.
-- **Context Menu (`src/app/features/room/message/MessageContextMenu.tsx`):** Add "Remind me" option → opens date/time picker modal (reuse `JumpToTime.tsx` logic).
-- **Trigger (foreground):** `setTimeout` in a hook inside `ReminderMonitor` in `ClientNonUIFeatures.tsx` → pushes to `toastQueueAtom` in `state/toast.ts` when due.
-- **Trigger (background):** Use Service Worker — `setTimeout` in the main thread will not fire when the PWA is suspended.
-
----
-
-### Mobile Usability Audit — Methodology
-
-1. **Viewport & Touch:** All interactive elements must have at least `44px × 44px` touch targets. Audit for horizontal overflow (horizontal scrolling must be disabled).
-2. **Modal Responsiveness:** All modals (Settings, Profile, etc.) MUST cover the full screen on mobile, not float as overlays.
-3. **Sidebar / Panels:** On mobile, sidebar panels (Members, Bookmarks, Media) must become full-screen overlays (using a `Drawer` or `Modal` pattern) rather than side-by-side flexbox panels.
-4. **Input & Composer:** Ensure the composer doesn't get obscured by the mobile keyboard. Test focus trap and blur behaviors.

-## Implementation Notes
-
-### ⚠️ TDS DESIGN LAW (repeated here for emphasis)
-
-> Every TDS color, animation, glow, border, shadow, and font value MUST come from `/root/code/web_template/base.css`.  
-> Never hardcode hex values. Never invent CSS variable names.  
-> Key variables: `--lt-accent-orange` · `--lt-accent-cyan` · `--lt-accent-green` · `--lt-glow-*` · `--lt-box-glow-*` · `--lt-border-color` · `--lt-font-mono`  
-> Reference implementation: `/root/code/tinker_tickets/` (markdown.js, base.js, ticket.css)  
-> This applies without exception to every task marked `[IMPROVE]`, `[Build]`, or any UI change.
-
-### Design Rules
-
-- All new components must respect both TDS dark (`LotusTerminalTheme`) and TDS light (`LotusTerminalLightTheme`) modes
-- Non-TDS theme work (custom accent color, theme presets) uses vanilla-extract theme files — match the pattern in `src/lotus-terminal.css.ts`
-- Code syntax highlighting token classes: `.tok-kw .tok-str .tok-num .tok-cmt .tok-fn` (defined in `web_template/base.css`)
-- `folds AvatarImage` does NOT accept children — wrap Avatar components externally for overlays/frames/borders
-
-### CI/CD Pipeline
