Grade A leads have strong action intent, contact information, budget clarity, and near-term timing. They should be followed up within 24 hours.

Start from the estate, school net, family fit score, and stated timing. Avoid hard selling first. Use the agent brief to propose a clear next step.

Use viewing_scheduled only after the user has agreed to view one or more estates or receive a proposed viewing route.

Use closed only when the transaction or confirmed agency outcome is completed. Use lost when the user is no longer relevant, unreachable, or has chosen another route.
