Edge TTS generates audio but sendVoice fails for model-reply TTS tags in Telegram (auto / tagged mode)

증상

Behavior bug (incorrect output/state without crash)

원인

Model generated plausible but incorrect output due to insufficient grounding, missing verification, or high sampling temperature.

해결법

Additional information

• The /tts audio slash command works correctly — Telegram bot credentials and sendVoice API are functional • Both auto: "always" and auto: "tagged" fail; issue is not mode-specific • Including [[tts]] as first token in model reply (tagged mode) also fails • Workaround: generate MP3 manually with node-edge-tts and reply with + MEDIA:./voice.mp3 on separate lines
