The core principle is that effective software refactoring in domain-intensive systems requires a dual-state expertise: maintaining sufficient knowledge to identify relevant data structures (domain expert) while retaining enough analytical distance to decouple implementation details and enforce single responsibility principles. This concept operates within the intersection of Domain-Driven Design and Software Architecture, specifically addressing "Law of Demeter" violations caused by excessive object coupling. The abstract rule dictates that when refactoring functions with multiple responsibilities in a domain-specific context (e.g., finance), one must revise data models—such as adding custom fields—to internalize external dependencies rather than passing raw objects between unrelated logical units.
