WHY IT NEEDS A POLICY

Why change_invoice_status needs a policy

This tool modifies the status of an invoice (e.g., draft, sent, paid), which is a reversible state change. While it touches financial records, it does not move money or commit financial obligations—it only updates a workflow status field. This makes it a Write operation rather than Financial.
