Ordering Papers Series, No. 02: Failure Cost as an Ordering Mechanism: Why Systems Stop Ranking by Efficiency When Failure Becomes Expensive

This working paper develops failure cost as an ordering mechanism. It argues that when failure becomes expensive, systems stop ranking behavior primarily by efficiency, performance, or optimization value. Instead, they begin ranking possible paths by what can still be carried without threatening systemic viability. The paper explains how rising failure cost shifts authority from optimization logic to viability protection. It shows why systems preserve redundancy, delay efficient actions, narrow discretion, and reselect feasible paths when local failure can become system-level exposure. As part of the Ordering Papers Series, this paper provides the core mechanism through which systems reprice behavior under pressure.
