Finnish founding heritage is a cross-corridor early-arrival exception at hop 5 in the west_reach — a Finnish prospector-entrepreneur following economic opportunity rather than cultural migration networks. The "Port" modifier in the name reflects the transit-service character rather than geography. `spur_end` at hop 5 with `wave_4` settlement is consistent with a system reached in the active expansion wave, valued for its position at the terminus of a Kapteyn's Star branch rather than for environmental or resource qualities. The M1/M2V classification is the corridor's standard dim star environment, which is unremarkable and accurate — the system's significance is positional, not astronomical.
