- new Transcriber interface makes the recorder service engine-agnostic; WhisperEngine (local JNI) and new RemoteWhisperEngine (POST /inference, verbose_json, in-memory WAV upload via new WavEncoder) implement it - SessionConfig carries serverUrl; when set, BOTH the live pass and the final pass transcribe remotely (server owns the model, e.g. large-v3 on GPU); local engine remains the offline fallback - UI: Transcribe on: phone/server dropdown + server URL field, persisted in SharedPreferences; model controls grey out in server mode; manual Transcribe also routes to the server - network security config permits cleartext HTTP for user-configured LAN/tailnet servers (documented; HTTPS works either way) - WavEncoder round-trip unit test (11 total green); validated phone -> Tailscale -> R9700 with large-v3 before the app-side change
