bug(voice): auto-created ElevenLabs agents get the 10-minute default; the fix is manual and silently reverts #229

What

hub/src/web/routes/voice.ts finds-or-creates a "Hapi Voice Assistant" ConvAI agent per voice (getOrCreateAgent → createAgent). The creation payload sets conversation_config.tts.voice_id and never sets conversation_config.conversation.max_duration_seconds.

ElevenLabs therefore applies its own default: 600 seconds, ten minutes.

Why it matters

The operator hit the ten-minute cut-off, and it was fixed by raising max_duration_seconds to 1800 on each existing agent through the API. That fix is per-agent and manual, so:

• Every new voice used from HAPI silently creates an agent back at ten minutes.
• Anyone deleting and letting an agent be recreated silently reverts the fix.
• There is no sign of it anywhere until a conversation is cut off mid-sentence.

The account currently holds five agents, four of them auto-created and distinguishable only by a voice id in the name. Four are now at 30 minutes; one sits at 60.

Ask

Set a sane max_duration_seconds in the creation payload so a new voice does not regress to ten minutes, and make it configurable rather than hardcoded — the right value is an operator preference, and the cap is also the runaway-cost guard, since ConvAI bills by the minute.

Worth considering at the same time: the auto-created agents are all named "Hapi Voice Assistant [voice:]", which is unreadable in the ElevenLabs UI and makes it easy to change the wrong one by hand.
