Treating positive feedback as a malfunction overstates a real pattern — a healthy body uses it deliberately in specific, self-limiting processes, per Bio 2751.

In practice

Blood clotting cascades amplify deliberately, escalating clotting factor activation until a fibrin clot forms and the cascade halts.
