 Wave_2 settlement at hop 7 requires explanation: in the wave_2 period, the topology at this distance from the core was not fully mapped, and the founding families reached GJ 4A through a longer chain than the current two-hop path from GJ 829 to the inner-reach junction suggests. The current hop-7 designation reflects post-wave_3 topology with the full Reach gate network in place; the founding families navigated a sparser network and considered GJ 4A genuinely far. The dead_end with one aperture has been the topology throughout; the connection point changed as the network developed around the system, but the system's terminal position has always been its defining condition.
