However, most existing forecasters rely primarily on one-way inference, \\textit{i.e.}, mapping \\textbf{history} to \\textbf{target}, and overlook the structural information provided by a revised natural chain (``\\textbf{history} (model input) -- \\textbf{target} (ground-truth output) -- \\textbf{post-target continuation}''). The post-target continuation records how trajectories evolve after the target, which can help stabilize forecasting, but it is not observable at inference time.
