+The later native composition removes the blanket physical-module rate
+exclusions and connects Cunning's typed Homeworld second shipment.
+Its exact pending world frame binds the rate event and final price; unaffordable

+runtime paths use the older explicitly staged final-setup fixture; they are
+not represented as an original action-only chronology.
