The draft waits in `next_message_body` until a person sets `approval` to **Send** (Template 2 sends it). Only with `autoSend = on` in *Settings* are hot and warm leads approved automatically.\n\n**Tier and stage** are set by fixed rules in *Validate AI Output* (score thresholds in *Settings*), never by the model.\n\n**Before activating**: see SETUP-GUIDE.md.",
