RepairCost adds the worn share of hull armour priced as that share of the hull's price, and TryRepair restores it. The per-unit-of-wear charge is the larger of RepairFraction and SellFraction. TryBuy checks credits with the same boundary as TryRepair and charges after delivery. A 100-unit ore sale pins the commodity sell scale.
