 `wave_2` at hop 8 in a spur_end position is consistent with early transit-function settlement: the founding cooperative came because the gate connection was there and the habitable world allowed self-sustaining community. K0V classification is accurate. `spur_end` with two gates — inward to Freiholt, outward to Randsholm — is accurate. The transit-services economy is consistent with a waypoint system that has sustained itself on transit margin and local agricultural surplus for four centuries. The community developing its own character despite being defined by transit function is the brief's core concept, expressed through the governance subtlety around Randsholm.
