WHY IT NEEDS A POLICY

Why generate_analysis_excel needs a policy

The tool retrieves data (Read component) but its primary action is to *generate and export* a new Excel file with analysis tables — a reversible write operation. It does not execute arbitrary queries, delete data, or move money.

From the tool's definition Tool description states it will 'Fetch participant data from configured databases and export to Excel' — this creates a new file artifact (Excel workbook) that persists as modified data output.
