`wave_4` settlement for a five-gate hub reflects the late emergence of Altmark's commercial significance — the western outer corridor did not develop enough traffic to justify a major hub here until Wave 4 expansion created the outward branch systems. The K-type star is accurate to the header. `hub` with five gates is accurate; this is the second node after Hansestadt in the west_reach and its political and commercial weight should be felt. The German historical region name reflects the founding German-heritage consortium's explicit ambition for the system. MVG's significant footprint is consistent with the MVG corridor extending to hop 7-8.
