Status: OUT
The GoF's enabling stack ensures type integrity from creation through use: theoretical enablement (LSP-DIP-OCP) validates behavioral substitutability, while mechanical enablement (interface inheritance + creational patterns) controls which concrete types enter the system and under what constraints, yielding end-to-end type safety across the enabling layers.
Depth-5 — the enabling stack (depth-4) provides prerequisites while creational-substitutability (depth-4) ensures correctness; combining them establishes that the prerequisites guarantee correctness
