 - `WakeWordDetector` umgebaut — sucht Custom-Modell `/voices/wake_aria.onnx`, Fallback auf eingebautes `hey_jarvis`
 - Alter Code crashte: `wakeword_models=["aria"]` erwartet Dateipfad, kein Keyword
 
+**TLS Fallback (Bridge → RVS)**
+- Bridge versucht zuerst `wss://` (TLS), bei `ssl.SSLError` automatisch Fallback auf `ws://`
+- Konfigurierbar über `RVS_TLS_FALLBACK=true` in `.env`
+- Loggt deutlich wenn TLS gewollt aber nicht verfügbar ist
+
+**Audio-Rendering für App (Piper TTS via RVS)**
+- Bridge rendert Piper TTS → WAV → base64, sendet Text UND Audio gleichzeitig über RVS
+- App spielt Audio ab und zeigt Text parallel — Modus entscheidet ob Sprache oder nur Text
+- Voice Engine initialisiert IMMER (auch ohne Soundkarte in der VM)
+- STT/Wake-Word nur wenn Audio-Hardware vorhanden — graceful degradation
+- Neue Dependency: `react-native-fs` (base64 → temp WAV → Sound abspielen)
+
+**Chat-Persistenz (Android App)**
+- Chat-Verlauf wird in AsyncStorage gespeichert (letzte 500 Nachrichten)
+- Beim App-Start automatisch geladen — Konversation bleibt erhalten
+- Linearer 1:1 Chat, keine Threads
+
 **Neues Script: `get-voices.sh`**
 - Lädt Piper Stimmen (Ramona + Thorsten) von HuggingFace herunter
 - Neuer Installationsschritt in README
