- 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
