## Description

This project is a Python-based business rules engine designed to decouple application logic from source code. It provides a framework for defining and executing dynamic conditional logic, allowing system behavior to be determined by data criteria rather than hard-coded instructions.

The system distinguishes itself by offering a declarative policy framework that utilizes a domain-specific language to manage complex rules. By mapping internal object attributes to dynamic variables and registering executable actions, the engine enables the creation of automated decision-making workflows that can be adjusted without requiring full application deployments.

The engine includes administrative utilities for exporting metadata schemas, which describe available variables, operators, and actions. This configuration-driven approach supports the development of interfaces that allow non-technical users to manage and update business policies through external rule sets.
