    "# 03 — Regeneración de presupuestos\n",
    "\n",
    "**Hipótesis:** un mismo cliente (`customer_id` + `vehicle_id`) recibe N quotes antes de convertir. El centro \"regenera\" el presupuesto cuando descarta el de call_center y abre uno nuevo en TPV local.\n",
    "\n",
    "Definición operativa de regeneración:\n",
    "- Existe quote call_center previa (Q0) para el par cliente+vehículo.\n",
    "- Existe quote posterior (Q1...Qn) en un terminal de centro NO call_center, dentro de ventana D días.\n",
    "- Q1 puede tener distinto `order_id` que Q0 (regenera de cero) o mismo (reescribe — menos común).\n",

    "Métricas pedidas:\n",
    "1. Centros que MÁS regeneran (cuentan regeneraciones absolutas y % sobre quotes call_center recibidos).\n",
