A lender's financing may depend on buyer demand becoming credible, and the processor's throughput on equipment being installed; a dependency graph orders Pathway steps and exposes bottlenecks. A Dependency does not become a canonical Relationship unless an independently meaningful persistent Relationship is explicitly admitted.
