    Create a function that consolidates a student's nested competency scores across different learning domains into a single comprehensive assessment set. The input consists of grouped skill measurements where related abilities are clustered together (such as mathematical concepts or reading skills), and these need to be flattened into one unified set of scores for overall progress evaluation. The function should preserve all individual score values while eliminating the hierarchical structure of the skill domains.
