15.6.3 Fusión del wrist
El wrist corporal y el wrist de la red de mano son observaciones independientes del mismo nodo anatómico. Se recomienda una fusión ponderada por covarianza; si las observaciones discrepan por encima del umbral, se preservan ambas, se marca inconsistencia y se evita una corrección silenciosa.
