This contract is a critical component of the Rules Engine, enabling secure and flexible role management.

This contract serves as the primary Admin Roles facet for the Rules Engine. It is responsible for managing, mutating, and granting all admin roles, including policy and calling contract admin roles. It enforces role-based access control and ensures proper role assignment and revocation. The contract also provides mechanisms for proposing and confirming new admin roles.
