+**Fidelity requirement:** Summarize what actually happened — not what was intended or what would have been ideal. If a step failed, record the failure. If a result was ambiguous, record the ambiguity. If the agent's approach was wrong and corrected, record both. Do not revise history to make the prior work look cleaner than it was. An accurate summary of a messy situation is more useful than a polished summary of a fictional one.`;
