Quality steering operates at the video/observation level, retaining full supervision for rollouts of all quality levels; quality-weighted supervision operates at the action level, reweighting the imitation loss, so that successful segments receive higher action cloning weights, and failed segments have their share in the action loss reduced while retaining their contribution in the world modeling loss.
