DIP provides a structured architectural mechanism: its two formal statements define the principle, its two implementation strategies (direct packaging and independent packages) provide concrete realization paths, and its ownership rule (abstractions belong to the higher layer) establishes dependency direction — together these elements reduce ambiguity in application.
Three independently specified DIP aspects (definition, strategies, ownership) together form a complete application guide with no gaps
Depends on (SL): dip-two-formal-statements, dip-two-implementation-strategies, dip-abstractions-owned-by-higher-layer
