RulesEngineForeignCallFacet

Git Source Inherits: FacetCommonImports Author: @mpetersoCode55, @ShaneDuncan602, @TJ-Everett, @VoR0220 This contract is a critical component of the Rules Engine, enabling secure and flexible data management. This contract serves as the data facet for the Rules Engine Foreign Call Components. It provides functionality for managing foreign calls. It enforces role-based access control and ensures that only authorized users can modify or retrieve data. The contract also supports policy cementing to prevent further modifications.
