A call missed at 11 PM — does the text go out at 11 PM?

No: sends stay within the legal 8 AM–9 PM window in your caller's timezone, even if the call lands at 3 AM. The missed call is logged immediately, qualified, and the first text goes out at the first allowed slot — 8 AM sharp. The AI doesn't sleep; it politely waits. For genuine overnight emergencies, escalation is separate: if the score reaches your threshold, you're alerted instantly by push and text, whatever the hour — because it's you who decides whether it's worth waking you.
