Buying signals move the stage. Guesses don't.
- A price question, a booking question or “I'm interested” moves the customer to Interested, marked hot or warm
- A clear “not interested” or “no thanks” moves them to Not Interested — a soft “not now, but what's the price?” counts as interest, not a no
- It never downgrades a Confirmed or Converted customer, and STOP is treated as consent to stop messaging, not as a sales verdict
