outer limit
Maximum allowable extent
The outer limit is the farthest boundary or maximum extent of something.
It marks where a territory, capability, or concept ends: the outer limits of the solar system, pushing the outer limits of human endurance.
Often plural, outer limits suggests the extreme edge beyond which lies the unknown or impossible: testing the outer limits of what the technology can do.
