Structural patterns exhibit orthogonal organization that can support DIP-aligned boundary management: the boundary spectrum (Adapter/Facade) can help establish the abstraction boundaries that align with DIP across system interfaces at different scales, while the wrapping spectrum (Proxy/Decorator) augments behavior within compatible interface hierarchies for internal flexibility. This two-spectra organization tends to keep these concerns separate, reducing the risk of conflating interface-boundary adaptation with internal behavioral augmentation.
Structural patterns' two orthogonal spectra ensure DIP boundary management and internal wrapping don't interfere
