A frozen multimodal evaluator compares task relevance in both presentation orders while pixel and perceptual losses constrain local errors. On RT-1, matched experiments improved PSNR by 1.26 dB and reduced LPIPS by 11.93 percent relative to continued supervised fine-tuning; rolling histories also helped long sequences. The evidence covers the reported RT-1, BridgeV2 and RoboCasa setups, not open-world prediction.",
