Status: OUT
OO design's dual invariance across scale and classification is safely applicable in practice only while practitioners exercise principled judgment about abstraction boundaries — avoiding the trap of treating invariance as license for indiscriminate pattern application.
Scale and classification invariance could be misread as "apply everywhere"; the overgeneralization pitfall is the natural guard against this misapplication
