guard rails
Road edge protection
Guard rails are protective barriers along roads, bridges, or elevated platforms designed to prevent vehicles or people from going over an edge.
The term extends to any system of limits that prevents dangerous outcomes: The company put guard rails around how employees could use AI tools.
In software and AI, guard rails are built-in constraints that keep systems operating within acceptable bounds.
Also spelled as one word: guardrails.
