//! Compliance SDK Interface
//! 
//! This module provides an interface for developers to configure compliance
//! checks and policies in their applications built on Anya core.
//! 
//! The SDK interface allows for a flexible, builder-pattern approach to
//! compliance configuration while ensuring all necessary checks are applied.
