Usa PR #40613 y los metadatos generados que se muestran en este issue como caso de reproducción; sigue el punto de entrada de node-core-utils que detecta los metadatos de Fixes en los mensajes de commit. Se considera terminado cuando la prosa que menciona “fix” ya no produce una línea de Fixes incorrecta, mientras las referencias válidas de Fixes siguen detectándose.
