// - Empower (g): Maps subjects to roles within organizations
// - Use (g2): Maps concrete actions to abstract activities within organizations
// - Consider (g3): Maps concrete objects to abstract views within organizations
// - Permission (p): Grants role-activity-view permissions within organizations
//
// This separates concrete entities (subjects, actions, objects) from
// abstract security entities (roles, activities, views), allowing more
// flexible and maintainable access control policies.
