Status: OUT
The recursive structure subsystem achieves reliable temporally-extended operation — its self-contained infrastructure (Composite trees + Iterator traversal + Flyweight sharing + Visitor extensibility) reaching into the temporal dimension via Memento-based state capture — when the Composite transparency-vs-safety tradeoff is resolved, since unreliable leaf-composite distinction at the base would propagate unreliability through the entire temporal extension.
Temporal extension of the recursive subsystem inherits the Composite safety concern at its foundation
