The k-m transitional stellar class is unusual and reflects a genuine edge-case object rather than a catalog error. The ambiguity in the stellar classification is part of the planet's character: the light quality is neither standard K nor standard M, which contributes to the off-calendar agricultural timing and the slight foreignness visitors notice. Wave_2 settlement at this depth from Gateway is explained by the system's position in a different expansion direction than the dominant corridor — it was reached early via a different route before the current corridor topology was established.
