CultMath has no implicit conversions to or from Vector*, Quaternion or Color, so Assembly-CSharp converts explicitly with ToCultMath/ToUnity at each engine boundary: FieldDriver, GuidedProjectile(Manager), EntityInstance, ActionGameManager, HullCollider, GridObject, ShipInstance, ShieldManager, ItemPickup, FieldTester, PlaceUIElementWorldspace, MapMenuInput, MapRenderer, SectorRenderer and ZoneRenderer. CultMath math calls that were handed Unity vectors now take converted values; Vector3.Scale in FieldDriver becomes a float3 product, and ItemPickup's Vector3.Dot on float3s becomes dot. packages-lock.json records the cultmath git package at f0605367 and demotes com.unity.mathematics to a transitive dependency.
