Status: OUT
The GoF's recursive structure subsystem extends into the temporal dimension: the self-contained recursive infrastructure (Composite trees + Iterator traversal + Flyweight sharing + Visitor operations) combines with state capture's temporal extension of composition (Command/Memento enabling undo, replay, and temporal navigation) — enabling not just spatial manipulation of recursive structures but temporal navigation of their states, as concretely demonstrated by Memento-based iteration on Composite collections.
depth-5 connection of the recursive subsystem to temporal extension, grounded in Memento-based iteration over Composite structures
