The Business Logic Gatekeeper acts as a sentinel layer between code implementation and business intent. It ensures that while code may be syntactically correct, it still adheres to specific logical invariants. By using tools like check_compliance, register_rule, and query_rules, developers can enforce critical business truths--such as security requirements or financial integrity--directly within the development workflow. This prevents accidental violations of core logic during rapid iteration.
