WHY IT NEEDS A POLICY

Why token_kyc_grant needs a policy

This tool modifies the KYC status of an account on the Hedera blockchain, enabling token transfers for that account. It is a reversible write operation (KYC can be revoked), but carries high severity because granting KYC status unlocks financial token transfer capabilities and could be misused to authorize accounts that should not be permitted to transact with regulated tokens.

From the tool's definition Grant KYC (Know Your Customer) status to an account for a token. Required when KYC key is enabled on token to allow transfers.
