+# Prueba de la corrección del cierre directo de Klondike (P4a): con allow_partial=true conserva un prefijo legal cuando la profundidad impide completar la partida y registra el progreso final aunque no coincida con el muestreo cada cuatro movimientos. Respeta los límites existentes de profundidad, nodos y tiempo; con allow_partial=false mantiene la poda sin construir un parcial. Incluye P1 + P2a/P2c + P3 + P4, sin P5 ni P6.
