blast radius
How much of a system a single failure takes down with it.
Blast radius measures the scope of damage when something breaks — a small radius means one component fails in isolation, a large one means the whole machine goes down. A bug that halts the entire machine is a blast-radius failure because its impact is total rather than contained. Good design shrinks blast radius so faults stay local.
