The source text identifies the person as 'Cierra Johnson', not 'Cierra Riehl' as stated in the record. The role (Bookkeeper), organization (BERI), and start date (2019) are all confirmed, but the surname is different. This is a clear contradiction in the person's name, which is a critical identifier in a personnel record.
