Status: OUT
The GoF's dual behavioral subsystems achieve joint governance with classification permeability: the temporal and recursive subsystems are jointly governed and self-limiting through shared SOLID governance, while classification boundaries are demonstrably permeable yet safely crossable — the subsystems' shared governance is the mechanism that enables safe permeability across construction-computation and Creational-Structural-Behavioral boundaries.
Joint behavioral subsystem governance and classification permeability are co-enabled by the same stratum-spanning SOLID regulation
