WHY IT NEEDS A POLICY

Why confirm_terms needs a policy

This tool records the user's acceptance of Terms of Service, which is a write operation that creates a binding agreement or commitment on behalf of the user. While not directly financial, confirming ToS on a paid service with HBAR micropayments per call could implicitly authorize ongoing charges.
