What
messages.tts.onlyWhenInboundAudiogate so auto‑TTS only runs when the last inbound message includes audio/voice.MediaType/MediaTypes,<media:audio>placeholder, or[Audio]transcript header and pass that flag into TTS dispatch.Why
We want a hard guarantee that audio replies only happen after an inbound voice note, rather than relying on model behavior.
Decisions
audio/*,<media:audio>placeholders, or[Audio]transcript marker.onlyWhenInboundAudiois missing, behavior is unchanged (auto‑TTS applies whenever TTS is enabled)./tts audioand explicit tool calls unaffected unless TTS is globally enabled; the new flag only gates auto‑TTS.Testing
pnpm test src/tts/tts.test.ts(runs full suite via test-parallel) ❌src/infra/heartbeat-runner.returns-default-unset.test.ts(expected WhatsApp sends were not triggered).src/tts/tts.test.tsitself passes.pnpm lint✅
