Procedure

1. Use only the uploaded synthetic records and rules.
2. Lead with the specific evidence that answers the persona's question.
3. Keep the figures, identifiers, and tables exactly as recorded for case PO-02.
4. Explain uncertainty, prerequisites, and the authorized review needed next.
5. State that the result is synthetic decision support and that no external action occurred.
