What Is a Certified Execution Record (CER)?

AI systems are increasingly used to make decisions, trigger workflows, and interact with real-world systems. They are no longer just generating text. They are: evaluating transactions triggering automations calling external APIs interacting with financial and operational systems As this shift happens, one question becomes unavoidable: Can we prove what actually ran? Not what the system was supposed to do. Not what logs suggest it did. But what actually executed. Most systems today cannot answer that question with certainty. The Problem: Execution Without Evidence When an AI system produces a result, teams often need to answer simple questions: What inputs were used? What parameters or configuration were applied? What runtime or environment executed the task? What output was produced? Can we prove the record has not been changed? In practice, this information is often: incomplete fragmented across systems difficult to reconstruct impossible to verify independently Logs may exist, but th
