ISL 1.6.2: Formalizing Patterns in Complex System Specifications

ISL 1.6.2 addresses the ambiguity in real-world system design by formalizing patterns that already exist in mature projects. By introducing explicit role definitions (Domain, Business Logic, Test) and state qualifiers (external, internal, calculated), developers and AI systems can now interpret specifications with greater precision. This structured approach significantly reduces misunderstandings and ambiguity in large-scale system architecture and implementation.
