`wave_2` at `hop 4` for a three-gate junction is consistent with deliberate early development — wave_2 infrastructure investment specifically targeted junction-value systems as strategic assets. The secondary star label "G-type" in the task brief does not match the systems.db entry of M6 V, which is what the READ-ONLY system profile reflects. Korean heritage at a wave_2 east_reach junction aligns with the corridor's migration logic: Korean-heritage operators were among the early commercial participants in the east_reach's wave_2 expansion. The bicameral governance design is a plausible adaptation of Korean civil administrative traditions to a mixed commercial settlement context.
