    Design a function for an adaptive learning platform that analyzes a student's numeric response pattern to validate learning progression constraints. The function should verify that in the given numeric sequence, each digit appears no more times than its actual value (e.g., digit 3 shouldn't appear more than 3 times). This validation ensures the adaptive difficulty scaling follows pedagogical balance rules for optimal student learning.
