WHY IT NEEDS A POLICY

Why remove_role_from_member needs a policy

Removing a role modifies a member's permissions/access reversibly — an admin can re-assign the role at any time. It does not delete any data permanently, execute code, or involve finances. The blast radius is medium because losing a role can revoke access to channels or features, but it is easily undone.
