{"id":"recursive-subsystem-validated-and-governed","text":"The recursive structure subsystem shows evidence of being both internally validated and structurally coherent: Interpreter's role as a demanding client — requiring Composite infrastructure for its AST, Visitor extension for operations like type-checking and code generation, and depending on multiple infrastructure layers (Composite trees, Iterator traversal, Visitor operations, Flyweight sharing) — provides evidence for the subsystem's self-contained completeness. The subsystem's bidirectional OCP extensibility (new element types via Composite, new operations via Visitor) and integrated infrastructure layers suggest a first-class design domain for hierarchical object structures that is both internally complete and disciplined in its compositional capabilities.","truth_value":"IN","source":"","source_url":"","source_hash":"","justifications":[{"type":"SL","antecedents":["interpreter-validates-recursive-subsystem-completeness","recursive-structures-self-contained-subsystem"],"outlist":[],"label":"Interpreter validates that all layers exist;
