Status: OUT
The recursive structure subsystem is precision-bounded from above and resource-governed from below: Interpreter's grammar-complexity limitation establishes a practical ceiling on the subsystem's most sophisticated client, while the controlled-sharing meta-pattern (Flyweight via factory) provides memory-efficient resource governance at the infrastructure level — together defining the subsystem's operational envelope with both an applicability boundary and an efficiency guarantee operating through the composition paradigm.
