upper boundary
Highest allowed value
Upper boundary is the highest limit or maximum extent of something, marking where a range, category, or permissible zone ends.
In statistics and mathematics, it defines the top of an interval or set: The upper boundary of the confidence interval is 95.
More generally, it describes any ceiling or cap: Income above the upper boundary disqualifies you from the program.
