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

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

 # Lotus Chat — Manual Testing Guide
 
-**Generated:** June 2026 · **Updated:** July 2026 (added §O — threads, per-thread notifications, math, search cache, session hardening, audit wave, desktop CSP)
+**Generated:** June 2026 · **Updated:** July 2026 (added §O — threads, per-thread notifications, math, search cache, session hardening, audit wave, desktop CSP; added the **Automated coverage map** below — logic now pinned by unit tests, so manual QA can focus on the human-only surface)
 **Scope:** Everything landed on the `lotus` branch since the v4.12.3 merge that I (Claude) could **not** verify statically and that needs a human in a real environment to confirm. Work through it top-to-bottom; the highest-risk / hardest-to-reproduce items are first.
 
 > **How to report back:** For each numbered check, tell me **PASS** / **FAIL** (or **partial**). On any FAIL, include: what you saw vs. expected, the browser/OS (and whether web LXC 106 or the desktop/Tauri build), the theme you were on, and any **browser console** errors (F12 → Console). Screenshots help for anything visual.

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

+
+Per-slice bug hunt (5 agents: theming · calls · messaging · threads/presence/UX · rooms/mod/notif/infra/desktop), each **verified against current code** (already-fixed items not re-flagged; the heavily-audited hot paths came back clean). Residual findings below. `[live]` / `[desktop]` = needs a real call / the desktop app to confirm.
+
+**Embeds / URL previews**
+
+- [x] **[Med] Desktop (Tauri) CSP `frame-src` was missing `store.steampowered.com`, `www.mixcloud.com`, `widget.deezer.com`** → the Steam widget (shipped) + new Mixcloud/Deezer embeds were silently blocked (blank iframe) **in the desktop app**. **FIXED** (`cinny-desktop` `daba59b`): all three added to `frame-src` (no `connect-src` — these don't do a client oEmbed fetch). Web was always fine (`frame-src 'self' https:`). Needs desktop-app QA to confirm the widgets render.
+- [x] **[Low]** `searchCache.ts` encrypted-search index has no size/count cap — unbounded on-disk growth (mitigated by the manual "Clear cached index" + logout wipe). **FIXED** (`fff811cb`): per-room cap of 5000 rows, oldest-by-ts evicted on write via a self-chaining IDB cursor + pure unit-tested `evictCount`. IDB-spec correctness (cursor delete/continue, tx liveness, range bracketing) confirmed by 2 review agents since CI can't run IndexedDB.
+- [x] **[Low]** `MsgTypeRenderers.tsx` `MLocation` OSM permalink uses raw `geo:` lat/lon substrings, not the validated floats — harmless (URL context, malformed input only). **FIXED** (`8a461610`): permalink uses the `parseFloat`+`isFinite` validated `lat`/`lon` (as the map iframe already did).
+
+**Voice / video calls**
+
+- [x] **[Med]** `DenoiseTester.play()` (Settings → Calls A/B model test) leaks the denoise model node — calls `ctx.close()` but never `denoise.dispose()` (inconsistent with `stopLive`, which disposes) → leaks the DeepFilterNet/DTLN worker/WASM per press. **FIXED** (`c9d9d914`): `stopPlayback` now mirrors `stopLive` (dispose model + gate), and a generation token also closes the rapid-click / stop-during-load / unmount-during-load leak windows (3 review passes, all 6 interleavings traced).
+- [x] **[Med] [live]** PiP auto-spotlight never released on return to the call room — the release branch sits inside the `if (!pipMode) return` guard, so screenshare→PiP→back leaves spotlight forced on and `pipAutoSpotlightRef` stuck `true`. `CallEmbedProvider.tsx:733-744`. **FIXED** (`08e19100`, code-level; still wants live QA): effect guards only on `!callEmbed`, releases whenever `pipMode && pipScreenshare` is false; + ref-reset on embed teardown + deps comment (2-agent reviewed).
+- [x] **[Low]** DenoiseTester async paths (`getUserMedia`) have no mounted-guard → ctx/stream leak + setState-after-unmount if Settings closes during the mic prompt. **FIXED** (`c9d9d914`): a `mountedRef` guards `startLive`/`startRecord` after the `getUserMedia` await (and `play()` after its model load); the ref is set on mount, not only cleared on unmount, so it survives a StrictMode/Activity remount.
+- [x] **[Low]** Soundboard 30s safety timeout never cleared on natural clip end (`CallSoundboard.tsx:115`); `PrescreenControls` `PermissionStatus.onchange` not removed on unmount (`PrescreenControls.tsx:22-28`). **FIXED** (`56561627`): per-play timer token cleared on end/unmount (identity-guarded so a stale clip can't disarm a newer one); permission `onchange` detached + `cancelled`-guarded setState.
+- [ ] **[Low] [live]** Call-to-call switch disposes the embed without an explicit `HangupCall` → possible transient ghost RTC membership until EC's unload-leave fires.
+
+**Theming / visuals**
+
+- [x] **[Med]** `invalidateDecorationCache` clears the module cache but has no pub/sub → changing **your own** avatar decoration doesn't update live in already-mounted avatars (timeline/members) until remount. Add a listener set / bump counter. `useAvatarDecoration.ts:67`. **FIXED** (`29ff1654`): per-user listener set notified on invalidation (+ clears the give-up counter); concurrent re-fetches de-dupe via the existing `pending` map.
+- [x] **[Med/Low]** Decoration picker grid thumbnails use the raw `DECORATION_CDN` constant instead of `decorationUrl()`, ignoring the `VITE_DECORATION_CDN` override → broken thumbnails if decorations are repointed. `ProfileDecoration.tsx:51`. **FIXED** (`29ff1654`): grid uses `decorationUrl(slug)`.
+- [x] **[Low]** Seasonal "Auto" is computed once at mount (no ticker, unlike NightLight) → won't flip across a holiday-window boundary in a long-lived session. `SeasonalEffect.tsx:100`. **FIXED** (`d416c62b`): hourly re-eval ticker (auto only) + refresh on entering auto; decision extracted to pure `resolveSeasonTheme` + tested.
+- [x] **[Low]** Selecting seasonal "Auto" while a chat background is set is a silent no-op (asymmetric mutual exclusion — SeasonalEffect early-returns when `chatBackground !== 'none'`). `General.tsx:550`. **FIXED** (`d416c62b`): any active seasonal mode (incl. auto) now clears the chat background; only "off" leaves it (symmetric with the bg picker).
+- [x] **[Low]** Decoration settings fetch the `/{field}` sub-resource → console 404 for users with no decoration set. `ProfileDecoration.tsx:79`. **FIXED** (`29ff1654`): reads the full `/profile/{userId}` (matching `useAvatarDecoration`); PUT/save path unchanged.
+
+**Threads / presence / UX**
+
+- [x] **[Med]** `PresenceBadge` renders DND (`unavailable` + `status_msg:'dnd'`) as a **yellow "Idle"** badge + label, while `PresenceRingAvatar` correctly shows **red** — inconsistent. Give the badge the same `status === 'dnd' → Critical` + "Do Not Disturb" branch. `Presence.tsx:17-59`. **FIXED** (`29ff1654`): badge now matches the ring + settings picker (Critical / "Do Not Disturb", `'dnd'` sentinel line suppressed).
+- [x] **[Med]** Collapsible-message threshold is hardcoded (`COLLAPSE_MAX_HEIGHT = 320`), but the docs claim it's "configurable in Settings → Appearance (default 20 lines)" — unimplemented. Add the setting + control, or fix the doc. `MsgTypeRenderers.tsx:38`. **FIXED** (doc): LOTUS_FEATURES now describes the fixed 320px (≈20-line) threshold; the full 320px is sensible and a per-user setting wasn't worth the surface — reconciled the doc rather than build a marginal setting.
+- [x] **[Med/Low]** In-app toast container has no visible cap / scroll — a burst of messages across rooms while focused stacks toasts unbounded and can cover the viewport. Cap visible N or `overflow-y:auto` + max-height. `LotusToastContainer.tsx:223-247`. **FIXED** (`1963222d`): queue capped at 5 in the atom writer (drops oldest non-sticky, never the newest or a sticky action toast) + container maxHeight/overflow + scroll-to-newest; +4 tests. (3 review passes — the 2nd caught a newest-dropped edge when the cap is full of stickies.)
+- [x] **[Low]** "Unread First" room sort leaves the (larger) read portion unordered — no activity fallback for the equal-unread case. `Home.tsx:213-222`. **FIXED** (`1963222d`): `factoryRoomIdByUnread` breaks ties by recent activity; relocated to `utils/sort.ts` (pure) + unit-tested.
+- [x] **[Low]** Tab title "(N)" counts mentions, not unread messages (doc says unread) — reconcile doc vs. code. `ClientNonUIFeatures.tsx:120-123`. **FIXED** (doc): the mention-count + unread-dot behavior is intentional (mirrors the favicon); LOTUS_FEATURES now describes it accurately (N = highlights, `·` = other unread).
+
+**Rooms / moderation / notifications / infra / desktop**
+
+- [ ] **[Med] [desktop]** `useTauriFocusAssist` never queries the initial OS Focus-Assist state on mount (unlike `useTauriDnd`, which rehydrates via `get_tray_dnd`) → if Focus Assist is already ON at launch, notifications/sounds leak through until the OS state next flips. Add a `get_focus_assist` mount query (confirm whether the native poll emits an initial reading). `useTauriFocusAssist.ts:18-24`.
+- [x] **[Low]** Push-rule enable toggle holds stale local `useState` after an external rule change (toggled on another device) — sync from the `pushRule.enabled` prop. `PushRuleEditor.tsx:55-79`. **FIXED** (`2c0cd0d2`): `useEffect` resyncs on `pushRule.enabled` change (prop flows from live `useAccountData(m.push_rules)`; no optimistic conflict).
+- [x] **[Low]** Server-support `.well-known/matrix/support` is fetched from `mx.getHomeserverUrl()` (client-API host) instead of the MXID **server-name** host → silently missing on delegated/split-domain servers. `About.tsx:45-47`. **FIXED** (`2c0cd0d2`): fetched from `https://{mx.getDomain()}` (MSC1929-correct); identical for non-delegated, graceful catch otherwise.
+- [x] **[Low]** Cleared/partial quiet-hours `time` input (`''` → window inactive) silently disables the window while the toggle still reads "on" — no feedback. `SystemNotification.tsx:364-382`. **FIXED** (`5175c095`): inline Critical hint when the toggle is on but a time field is empty.
+- [~] **[Low] [desktop]** Native quick-reply swallows send errors (`.catch(() => undefined)`); the `show_rich_toast` trigger has no verified web-side caller. `useTauriToastActions.ts:35-38`. **ROOT CAUSE FOUND + web fix shipped** (`0ddf86c6`): `show_rich_toast` was dead because `showOsNotification` preferred the service worker (WebView2 has one), shadowing the injected `window.Notification` shim. Now skips the SW path under Tauri → notifications route to the rich toast, whose click navigates to the message.
+
+### 🖥️ Desktop notification rich-toast — follow-ups (activated by `0ddf86c6`, need a Windows build)
+
+The web-side nav fix (`0ddf86c6`) makes the native rich-toast path live for the first time. It fixes click→navigate, but exposes latent behaviors in the **cinny-desktop Rust** that need a Windows build to fix + verify:
+
+- [ ] **[Med] [desktop]** **Tag-coalescing lost.** The web SW notification used `tag` to _replace_ prior notifications for the same room; `show_rich_toast` (`cinny-desktop/src-tauri/src/native/toast.rs`) ignores `tag` and shows a new WinRT toast every time → rapid same-room messages stack instead of collapsing. Fix: dedupe/replace by room in the toast store (`toast.rs:226-230`).
+- [ ] **[Med] [desktop]** **Thread / invite quick-reply misroutes.** The reply target is the coalescing `tag` — `${roomId}:${threadId}` for thread replies, `'lotus-invites'` for invites (`ClientNonUIFeatures.tsx:471,192`) — not a real room id, so `mx.sendMessage(tag, …)` fails silently (`useTauriToastActions.ts:37`). Body-click navigation is correct (uses `path`). Fix: pass the real `roomId` separately (e.g. `data.roomId`) and have the shim (`lib.rs` `NOTIFICATION_BRIDGE`) + `toast.rs` use it for the reply target; keep `tag` for coalescing. Invite toasts should also drop the reply box (nothing to reply to).
+- [ ] **[desktop QA] Windows notification checklist** (verify `0ddf86c6` + the above): (1) confirm the pre-fix symptom was focus-without-navigate; (2) message toast → click navigates to the message, quick-reply sends to the room; (3) thread toast → navigates, reply currently misroutes (until fixed above); (4) invite toast → navigates to invites; (5) rapid same-room messages → stacking until coalescing restored; (6) AUMID-missing/dev build → plain-notification fallback still shows; (7) web PWA unaffected.
+- [x] **[Low]** Export-history date-range early-break can over-paginate + mislabel "truncated" in E2EE rooms (`oldestRawTs` only advances on decrypted `m.room.message`, so undecryptable old events never move it). `ExportRoomHistory.tsx:104,136`. **FIXED** (`3ff8fb8e`): boundary now advances on every event (getTs is envelope metadata), above the type/decryption filters; guarded `ts > 0` so a bogus 0-ts can't cause the opposite (silent under-pagination). 2-agent reviewed.
+- [x] **[Info/doc]** `PolicyListViewer` is a manual room-ID/alias viewer with **no** subscribe/unsubscribe controls and no subscribed-lists listing — `LOTUS_FEATURES.md:1287` describes both. Docs oversell; not a runtime bug. **FIXED** (`8a461610`, doc): LOTUS_FEATURES corrected to describe the read-only room-ID/alias viewer (no subscribe controls).

+### ✅ Composer autocomplete-insert crash (reported 2026-07) — FIXED (`477df4ae`)
+
+Picking an autocomplete item (mention/emoji/command) occasionally tripped the composer error boundary ("encountered an error" → forced refresh) even though the element inserted. Root-caused (3 agents, incl. a headless slate simulation) to `moveCursor` deferring its cursor work to `setTimeout`, leaving the caret on the just-inserted inline-void's zero-width edge; slate-react's commit-phase `setBaseAndExtent(voidEdge, 1)` then threw `IndexSizeError` mid-render → boundary. **Fix:** do `Transforms.move` (escape the void) + `insertText(' ')` synchronously in the same commit as the insert, so the caret is a resolvable text point when the selection sync runs. Plus a recoverable boundary ("Reload composer" + `onReset` deselect) so any residual composer crash no longer needs a page refresh. (A first "sync insertText without move" attempt was caught in review — the void guard drops the space + traps the caret; `move` is required.)
+
 ### ✅ Unread/read-receipt flakiness (reported 2026-07) — FIXED (pending prod QA)
 
 Room unread dots were inconsistent: reading a message sometimes cleared the dot, sometimes left it stuck, sometimes it resurrected. Root cause (confirmed by tracing + diffing upstream cinny `dev`): **our own "N4" change.** `handleReceipt` recomputed via `getUnreadInfo`, which reads `room.getUnreadNotificationCount()` — server-computed and **stale on the synchronous synthetic receipt echo** (SDK only zeroes it immediately when the last event is your own message) → it PUT the stale non-zero count back → stuck/resurrecting. Compounded by `hasUnread = !!unread` lighting the dot on any present map entry, incl. phantom `{0,0}` PUTs from our `UnreadNotifications` listener. Plus a Mark-as-Unread (MSC2867) flag that never cleared on opening an already-read room (no receipt → no auto-clear).

+### [PARKED] Matrix 2.0 call membership — MSC4354 Sticky Events (investigated 2026-07, 3 agents + live infra check)
+
+Move MatrixRTC/Element Call call-membership from state events (MSC3401) to **sticky events** — the "Matrix 2.0" path. **Not a flag flip; a coordinated rollout. Parked deliberately.**
+
+Findings:
+
+- **Server (Synapse 1.157.1, LXC 151):** `msc4354_enabled` defaults `false`. Enabling is **low-risk, additive, reversible** — schema (`sticky_events` table) already ships unconditionally, no migration/backfill, all runtime paths flag-gated, residual rows self-expire ≤1h. The one historical `/sync` EDU-filter bug (#19787) was fixed in 1.155.0; SQLite guard N/A (we're Postgres).
+- **The flag alone is a no-op for behavior.** Our EC fork (upstream **v0.20.1** base, `@lotusguild/element-call-embedded`, bundled into Cinny at build → fleet upgrades atomically) gates sticky mode behind BOTH server support AND a per-device **developer-settings** radio (`matrix-rtc-mode`, defaults `Legacy`). Enabling the flag only un-greys that radio; no client changes what it sends until a human toggles it.
+- **Matrix-layer mixed-mode = safe:** js-sdk (v41.6.0) reads + merges sticky and state membership, so cross-mode participants see each other.
+- **Open risk before any real rollout:** media layer. Sticky mode drops `livekit_alias` + uses lk-jwt-service `/get_token` (slot `m.call#ROOM`); legacy uses `/sfu/get` (`room=roomId`). Both endpoints are **live** on our lk-jwt-service, but whether they resolve to the **same LiveKit room** is unverified — must confirm with a **two-account cross-mode test call** (one device `Matrix_2_0`, one `Legacy`) before changing the default, else split-at-media.
+
+To actually adopt (future): (1) enable `msc4354_enabled: true` + restart; (2) two-account media-interop test; (3) if unified, flip EC default mode `Legacy`→`Compatibility`/`Matrix_2_0` in the fork + redeploy; (4) keep legacy fallback during transition. **No user benefit until step 3.**
+
+### [ ] Matrix 2.0 call membership — MSC4354 sticky events (INVESTIGATED 2026-07, deliberately NOT enabled)
+
+3-agent investigation after the 1.157.1 upgrade (EC-fork behavior · Synapse/upstream readiness · client-fleet composition). **Conclusion: leave `msc4354_enabled` OFF for now** — enabling it is safe but delivers **zero user-visible benefit on its own**, and introduces a latent footgun.
+
+**Why it's a no-op alone:** the EC fork's `doesServerSupportUnstableFeature(MSC4354)` probe feeds **exactly one thing** — whether the "Matrix 2.0" radio in **Developer Settings** is greyed out (`DeveloperSettingsTab.tsx:349-353`). The real switch is the per-device `matrixRTCMode` setting (`settings.ts:149-152`), which **defaults to `Legacy`** and never auto-enables. Sticky sending is gated at `LocalMember.ts:862` (`unstableSendStickyEvents: mode === Matrix_2_0`). So flipping the server flag changes nothing any client sends.
+
+**Verified safe:** Synapse-side is **additive and cleanly reversible** — the `sticky_events` schema ships unconditionally (no migration/backfill on enable), every write/read/serialize/replication path is flag-gated, disabling stops it instantly and residual rows self-expire ≤1h. The one relevant bug (#19787 `/sync` EDU-filter) was fixed in 1.155.0; the SQLite<3.40 guard doesn't apply (we're on PG 17.10). Matrix-layer **mixed-mode visibility is safe**: js-sdk `collectMembersEvents` reads **both** sticky and state membership and merges them, so sticky-mode and legacy-mode participants see each other. Our `lk-jwt-service` already serves **both** JWT endpoints (legacy `/sfu/get` **and** the sticky-mode `/get_token` — both probed live, 400-with-validation-error = present). EC is bundled into cinny's build (`@lotusguild/element-call-embedded`), so the fleet upgrades **atomically** — the "all EC clients ≥ v0.17.0" precondition is structurally guaranteed for our own users.
+
+**The one unresolved risk (blocks a real rollout, not the flag):** sticky mode drops `livekit_alias` and uses `/get_token` (slot `m.call#ROOM`) while legacy uses `/sfu/get` (`room=roomId`). **Whether both resolve to the same LiveKit room is a property of lk-jwt-service, not the client** — unverified. If they diverge, cross-mode participants appear in each other's member list but are **split at the media layer** (silent, no error). Requires a **two-account test call** (one device on Legacy, one on Matrix 2.0) to confirm before anyone relies on it.
+
+**If we ever do this:** (1) run the two-account media-interop test; (2) only then consider enabling `msc4354_enabled: true` in `/etc/matrix-synapse/homeserver.yaml` (LXC 151) + restart; (3) treat a default-mode change as a separate coordinated EC rollout. MSC4354 is still **OPEN upstream** (not in FCP, `needs-implementation`), so this stays experimental regardless.

+- [ ] **Runtime mobile QA** — none of the above is validated on an actual phone (static analysis only). Needs device/devtools walk-through per LOTUS_TESTING §E.
+- [x] **Element Call fork in-call mobile UI** — DONE (`element-call:lotus` `e36aef8a`, 3-agent survey + 2-agent review). Fixed the EC iframe's own phone UI: footer control row wraps so hangup can't clip (320–500px), portrait 1:1 self-PiP safe-area inset, 44px camera-flip + reaction-picker targets, settings-tab horizontal scroll, landscape spotlight filmstrip. All mobile-gated (EC is mobile-first CSS). Rides to users on the next fork republish (P6-2). Runtime on-device QA still pending (needs a phone).
+- [ ] **M2 — touch discoverability** — message quick-reactions/actions are hover-gated; long-press is the fallback but is **unreliable on iOS Safari** (deep audit). A visible touch affordance is needed but the naive fix hides unread badges / clutters messages (member-profile-style redesign).
+- [~] **Sub-44px touch-target sweep** — primary controls DONE via a shared `MobileTouchTarget` `@media` class (`P1`, `8a1168bc`): in-call bar ×7, call-status bar ×4, thread "N replies" chip, knock Approve/Deny, ACL remove.

These fragment cards render header/thumbnail beside content as direct children of the `UrlPreview` flex row; added `StackOnMobile` (mobile-only `@media (max-width:750px){ flex-direction:column }`) scoped to those variants via `cardClass`. folds `Box` has no default `direction` so the override wins uncontested; desktop unchanged (verified by 2 review agents). Pre-existing desktop quirk (header bar beside content on Twitter/TikTok at desktop width) left as-is — the fuller fix is wrapping each card body in a column `Box`; out of scope for a mobile pass.
+- [ ] **M2 — message action/quick-reaction touch discoverability** — hover-gated + iOS-long-press-unreliable; a visible touch affordance collides with unread-badge placement / per-message clutter → needs a design decision + device look.

Grounded in prod CSP (`frame-src https:` allows the widget with no infra change; images via homeserver `mxc`; NO client-side Steam API — `connect-src` + Steam CORS both block it, which is the honest ceiling: no review scores/genres/screenshots client-side). **Needs on-device QA:** the live widget iframe height/fit (can't render headlessly) — verify the price/Buy stay visible on desktop-wide and phone.

Root cause: **Synapse's `/thumbnail` endpoint flattens animated GIFs to a still first frame**, and every preview image went through it. `GifCard` (Giphy/Tenor) + the generic OG card now request the **original** via `/download` (`mxcUrlToHttp` with no width/height) when the preview is a GIF (`og:image:type === 'image/gif'` or a `.gif` pathname). Guarded: `shouldServeGifOriginal()` keeps the frozen thumbnail past a **10 MB** `matrix:image:size` cap, and the generic card's eager `<img>` gained the `loading="lazy"` it was the only preview image missing. Also added **Mixcloud + Deezer** audio embeds, and fixed Deezer podcasts (they live at `/show/<id>`, **not** `/podcast/<id>` — the latter 404s on Deezer's own oEmbed; verified against the live API). **Needs on-device QA:** confirm a large GIF still animates and doesn't stall the timeline.

+**✅ Embed bug hunt (2026-07, 3 survey agents + 2-agent review) — `f2673eff`.** Core posture verified **sound** (iframe sandbox, `useIframeAutoHeight` postMessage origin+source trust, no XSS/`dangerouslySetInnerHTML`, `rel="noreferrer"` on all 21 links, oEmbed no-SSRF, the whole facade→iframe/abort/observer lifecycle). Fixed: Twitch/Kick/SoundCloud/Streamable reserved-path over-match (utility pages rendered as broken players), Vimeo hash over-capture (`[0-9a-f]{6,}`), Spotify/Steam/Discord/IMDb `og:image` now via `mxcUrlToHttp` (was a broken raw `mxc://` `<img>` + a pre-click 3p-request facade bypass), `wide` class follows the og:url-resolved embed, Twitter host alignment (`mobile.twitter.com`/`/statuses/`), URL de-dupe.

+- **Security-vs-functionality tradeoff (needs a call):** drop `allow-popups-to-escape-sandbox` and/or `clipboard-write` from `EMBED_SANDBOX`/`allow=` on embed iframes — real hardening against a _compromised_ provider (phishing popup / clipboard hijack), but risks breaking a legit provider popup/copy on the trusted major providers we embed. Low marginal value; not shipped blindly.
+- **Defense-in-depth:** `encodeURIComponent` the Bluesky authority + Apple Music path/search interpolated into the embed `src` (not currently exploitable — host is fixed and value comes from `URL.pathname`; React escapes the attribute).
+- **Out of embed scope (real, low-sev):** `LotusDenoiseFeature` (`ClientNonUIFeatures.tsx`) has a `window` `message` listener with **no origin/source check** → any frame/window can post `{type:'lotus-denoise-status', error}` and pop a forged **"System"** toast (text only, no XSS). Validate `event.source`.
+- **Lifecycle Lows (cosmetic/latent):** a re-fetch flips a playing embed back to the spinner (latent — url is keyed); auto-height retained across close→reopen; `extractEmbedHeight` generic `.height` fallback accepts any allowed-origin message; `TweetEmbed` theme is a one-time `matchMedia` snapshot (no live theme switch); host-normalization gaps (`vt.tiktok.com` misses `StackOnMobile`, `m.instagram.com`, `www.youtu.be`).

Safe for deploys because `lotus_deploy.sh` now **follows origin/lotus HEAD** each poll iteration + resets to the gated SHA (`matrix` `c15a489`) — closes the latched-SHA freeze race.
+- [x] **Hard quality gates** — typecheck/eslint/prettier promoted from `continue-on-error` to blocking (tree held clean). eslint gates on errors only; `no-explicit-any` warnings stay informational.
+
+**CI follow-ups (open):**
+
+- [ ] **Dedicated `desktop-linux` runner** (infra) — concurrency only collapses _burst_ stacking; a single in-flight `build-linux` (Tauri, `ubuntu-latest`) still shares the runner with web CI and can queue a web CI/deploy up to ~30 min. Fix = register a 2nd Linux act_runner labelled `desktop-linux` (root, network, RAM for a Tauri build; do NOT also label it `ubuntu-latest`) and point only `build-linux: runs-on` at it. Relabeling without a matching runner hangs the job forever.
+- [ ] **Debounce the desktop trigger** — `trigger-desktop` fires a full desktop build on _every_ lotus commit; consider tag/`workflow_dispatch`/schedule-gating to decouple desktop cadence from web commits (biggest remaining runner-load source).
+- [ ] **Verify Gitea ≥ 1.24** actually honors workflow `concurrency` (older silently ignores it → safe no-op, but the change is then inert — confirm on a test burst).
+- [ ] **Deferred (chosen-not-now):** build-once/deploy-the-artifact (kill the CI-then-deploy double build); CI-gate the `lotus-build.sh` upstream-merge path (currently builds+deploys+then pushes, bypassing CI).

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

+### Local Development
+
+Lotus Chat is a **pure client — there is no backend of its own to run.** It talks directly to a Matrix homeserver (Synapse) over HTTPS, so the only thing you run locally is the Vite dev server; it connects to a real homeserver for all data. If you were looking for "the backend to pair with it," there isn't one — that's the homeserver.
+
+**Prerequisites:** Node 20+ (CI builds on Node 24) and npm.
+
+```bash
+npm ci        # deps; @lotusguild/* come from our Gitea npm registry (public read — no auth/token needed)
+npm start     # Vite dev server → http://localhost:8080
+```
+
+The dev server defaults to **port 8080** (`vite.config.js`); if 8080 is already in use it falls through to 8081+, so check the "Local:" URL Vite prints on startup. If it boots but the page renders blank, it's almost always a failed module/asset resolution, not a "missing backend" — open the devtools console and read the first error.
+
+**Which homeserver / logging in:** `config.json` sets `defaultHomeserver: 0` → `matrix.lotusguild.org`, so you sign in with your normal `@you:matrix.lotusguild.org` account. That homeserver is **live production** — anything you send is real, so keep test traffic to a DM with yourself or a throwaway room. To develop fully isolated instead, point `config.json` at a throwaway `matrix.org` account (already in `homeserverList`) or a local Synapse.
+
+- **SSO / OIDC works from localhost.** Login goes through Authelia via OIDC dynamic registration; the provider redirects back to `http://localhost:8080/…` and the client registers that redirect on the fly, so no server-side allow-listing is needed. After the callback you may see a `GET …/_matrix/media/v1/thumbnail/… 404` — that's just a missing avatar thumbnail, **not** a login failure.
