Status: OUT
Factory Method's sole creational gateway operating within the fully governed stratum lattice achieves safe end-to-end creation governance only while Visitor's encapsulation breakage does not compromise the one inheritance role (type governance) that coexists with Factory Method's inheritance role (Template Method bridging) — if encapsulation breaks, the two-role inheritance model collapses and Factory Method's gateway status loses its architectural grounding.
Factory Method's governed gateway is safe unless Visitor's encapsulation breakage collapses the two-role inheritance model it depends on
