This book examines what responsibility looks like after failure has already occurred and damage cannot be undone. It explores how engineers, operators, and leaders inherit broken systems they did not design, must run them in degraded states, and make decisions where every option causes harm. Rather than focusing on prevention or optimism, the book addresses moral injury, accountability without justice, and the quiet labor of keeping systems running when stopping them is not possible. It is about living with irreversible consequences and continuing to act with integrity when repair is no longer available.
