Status: OUT
SOLID's cohesion and extension principles offer complementary lenses for reasoning about behavioral modification: SRP and ISP suggest a cohesion-based compass for principled decomposition — helping determine which modification dimensions warrant separation and which interfaces to expose — while OCP serves as a primary strategic decision point for variation management — helping select whether to extend by adding new types or new operations. Together, these principles can guide more disciplined navigation of the behavioral modification space.
Depth-7 — two independent SOLID governance mechanisms (decomposition via cohesion at depth-6 and extension strategy via OCP at depth-6) jointly cover the full governance problem of the modification space
