 `wave_4` at hop 7 is consistent with genuine frontier-push settlement arriving after the inner corridor was established. The K4V star is moderately cool and dim; the habitable zone is stable and unspectacular, which suits a system whose significance is industrial and political rather than environmental. `junction` topology at the Compact's geographic center means Freiholt's three gates are strategically important — controlling this junction is not feasible without Compact cooperation, which is part of why the Assembly treats it as a compliance problem rather than a military target. The name "Freiholt" is Germanic, original to this setting, and communicates the founding logic directly.
