`wave_3` at hop 11 reflects genuinely early frontier-push settlement driven by the subgiant's unusual habitability signature — surveyors noted the expanded habitable zone and the agricultural potential, and a wave_3 agricultural cooperative took the offer. The G8IVvar classification is the system's defining unusual element: a subgiant is rare in the gate network, and its evolutionary status creates a long-range narrative pressure that is appropriate for a deep-west system. `through_route` at hop 11 means Alshain is on the chain toward something further out — GJ 4056 beyond and back toward Randsholm. The name "Alshain" is a real Arabic star name (Beta Aquilae) and was already assigned to this system in the astronomical catalog; it is kept here as an example of a pre-settlement designation that stuck, a common enough occurrence for the handful of stars with traditional proper names.
