ElevenLabs Cloudflare returns 302 to a region-restricted help page
when requested from a Russian IP. Tablet host (.60) is in RU, so the
Stage 2 call was failing with 502 upstream.
Fix: use https-proxy-agent when ELEVENLABS_PROXY (or generic HTTPS_PROXY
/ HTTP_PROXY) env var is set. Tinyproxy on .103 (non-RU egress host)
acts as the tunnel.
- package.json: add https-proxy-agent ^7.0.6
- app/api/voice/tts: switch from global fetch to node:https with
explicit Agent (either direct or HttpsProxyAgent). Still streams
MP3 back via Readable.toWeb so Next.js Response pipes it to the
browser as audio arrives.
Operational: set ELEVENLABS_PROXY=http://192.168.31.103:8888 in
tablet.env after bringing tinyproxy up on .103.
Stage 2 of voice integration — centralizes TTS on the tablet so the
Python satellite no longer needs ElevenLabs credentials or mpv.
- app/api/voice/tts — POST {text, agent}, proxies to ElevenLabs
streaming endpoint with flash_v2_5 default, returns audio/mpeg.
Per-agent voice id via COSMO_TTS_VOICE / LUSYA_TTS_VOICE env.
- VoiceOverlay — on response/error events fetches TTS and plays via
HTMLAudioElement; on wake event stops playback (barge-in). Dismiss
timer extended by text length so long responses do not cut off.
- Autoplay caveat: browser may block first playback until user taps
anywhere on the page (FKB: enable Force Autoplay to bypass).
