    In an adaptive learning platform, develop a function that identifies and unlocks the next available skill level in a student's learning progression by finding the leftmost unmastered objective (represented as 0) in their binary progress pattern and marking it as mastered (changing it to 1). The function should take a binary number representing the student's current mastery status across different learning objectives and return the updated progress pattern with the next sequential skill level unlocked.
