+## M8Chat App2 — Current State (2026-04-10)
+
+Custom Flutter Matrix chat client (v1.2.0) deployed to app2.m8chat.au for testing.
+Production (app.m8chat.au) still runs the old FluffyChat fork — DO NOT deploy there.
+
+### What works
+- **Chat messaging** — rooms list, timeline, send/receive, reactions, replies, file upload, typing indicators
+- **E2EE (Olm/Megolm)** — Olm loads in browser, device keys upload, messages encrypt/decrypt between app2 and Element
+- **Spaces** — expandable space list with child rooms
+- **User search** — search Matrix user directory, start DMs
+- **Jitsi conferencing** — lazy-loaded iframe, no-login required
+- **LiveKit video/audio calls** — JWT fetch works, WebRTC connects, video+audio publish to LiveKit SFU
+- **Session persistence** — credentials in flutter_secure_storage, events in MatrixSdkDatabase (IndexedDB)
+- **Brave browser** — app loads and works (Olm included, graceful fallback if WASM blocked)
+
+### What is broken / incomplete
+- **Video call rendering — SCRAMBLED VIDEO from Element X**: Root cause identified. Element X sends media with `encryption: GCM` (AES-GCM frame encryption). App2 sends `encryption: NONE`. The LiveKit Flutter SDK needs E2EE frame encryption enabled to decrypt Element X video. This is the #1 priority fix.
+- **Incoming call detection**: App listens for old m.call.invite events. Element X sends MSC3401 call.member state events. Incoming calls from Element X to app2 are not detected.
+- **Avatar 404s**: ~10 room avatars return 404 on legacy /_matrix/media/v3/download/ path. Server may require authenticated media.
+- **Rooms list spam**: debugPrint in rooms_repository.dart dumps all 15 rooms to console on every sync. Needs removal.
+- **Old ghost devices**: 20 devices for @try user, 5 without keys (from pre-Olm builds). Should be cleaned up server-side.
+- **Red exclamation mark in Element**: Try device is unverified (no cross-signing). Cosmetic — requires manual verification or Phase 2 cross-signing.
+- **Profile screen**: E2EE status shows dynamically but notifications/cross-signing are placeholders.
+
+### Key file paths
+- **Project root**: /srv/wp-dev/pwa-sites/m8chat-app2/
+- **Web entry**: web/index.html (Olm load + fallback + Flutter bootstrap)
+- **App config**: lib/core/config/app_config.dart (server URLs, version 1.2.0)
+- **Matrix client**: lib/core/network/matrix_client.dart (MatrixSdkDatabase provider)
+- **Auth flow**: lib/core/auth/auth_notifier.dart + lib/features/auth/data/auth_repository.dart
+- **LiveKit service**: lib/features/calls/data/livekit_service.dart (JWT fetch, MatrixRTC state events)
+- **Call screen**: lib/features/calls/presentation/call_screen.dart (video rendering)
+- **Call controller**: lib/features/calls/presentation/call_controller.dart (state machine)
+- **Chat repo**: lib/features/chat/data/chat_repository.dart (timeline, send, react, redact)
+- **Jitsi service**: lib/features/jitsi/data/jitsi_web_service.dart (lazy script load)
+- **Build output**: build/web/ (flutter build web --release)
+
+### Server infrastructure (chat.m8chat.au)
+- Synapse 1.151.0 (healthy, 86 active users)
+- LiveKit 1.10.1 + lk-jwt-service (both healthy)
+- Element Web 1.12.15, Element Call
+- PostgreSQL on host (user: synapse_user, pass: kijPt4cPWkoaZk8BVm, db: synapse)
+- LiveKit WSS URL: wss://matrix.m8chat.au/livekit/
+- JWT endpoint: https://matrix.m8chat.au/_matrix/livekit/jwt/sfu/get
+
+### Deployment
+- **Target**: app2.m8chat.au (NOT app.m8chat.au)
+- **SSH**: m8chat@app.m8chat.au:2233 (key: ~/.ssh/m8chat_prod), path: public_html/app2.m8chat.au/
+- **Build**: cd /srv/wp-dev/pwa-sites/m8chat-app2 && flutter build web --release
+- **Deploy**: rsync -avz --delete --exclude='.htaccess' --exclude='.ftpquota' -e "ssh -p 2233 -i ~/.ssh/m8chat_prod" build/web/ m8chat@app.m8chat.au:public_html/app2.m8chat.au/
