 `unsettled` despite permanent population reflects a real ambiguity in Assembly settlement law — transit facilities are categorized differently from colonies, and this system has never been formally reclassified. `junction` with four apertures connecting both major corridor hubs and the outer west is consistent with a deliberate siting at a topological chokepoint. The M-type dim star with no habitable worlds explains why this is a station settlement rather than a surface one. The name from MVG reflects corporate founding origin consistent with the station-build era; transit facilities of this type were typically established in the Wave 3-4 expansion period even when they never received formal settlement classification.
