Status: IN
Recursive structures' complete infrastructure (Composite trees + Iterator traversal + Flyweight sharing + Visitor operations) is further enriched by Composite's natural Chain of Responsibility integration: parent references that define the Composite tree simultaneously define request-routing chains, yielding a recursive substrate that supports not just structure, traversal, sharing, and operations, but also behavioral request propagation — five pattern capabilities from one structural foundation.
Adding Chain of Responsibility to the recursive infrastructure yields five-pattern behavioral substrate from Composite
