WHY IT NEEDS A POLICY

Why move_emails needs a policy

Moving emails modifies their state (mailbox location) reversibly without data loss. This is a write operation rather than read (no query/retrieval only) or destructive (emails remain intact). Severity is medium because misuse could cause organizational chaos and potential loss of visibility into important emails if moved to incorrect/hidden folders, but the operation is reversible.

From the tool's definition Tool performs 'Move emails to another mailbox' - a reversible modification of email location/organization state.
