Aggregation module

[0xjei]

Create a modular aggregation layer capable of combining already deployed BaseChecker and/or AdvancedChecker contracts using various logical operators (e.g., AND, NOT, XOR). This aggregation layer should integrate seamlessly with the existing Policy (gatekeeper) contracts, allowing developers to construct complex access control policies from independently defined checker logic. The aggregation contracts will serve as orchestrators, evaluating multiple checkers against user-provided evidence and returning a single boolean result.

This approach reduces complexity and gas costs when there’s no need to reuse already deployed checks. The aggregation layer, therefore, becomes an optional yet powerful tool—useful when building sophisticated, multi-faceted access control policies, but not mandatory for simpler use cases.
