This paper introduces substrate reversal within the MID/QC framework, showing how coherence drain and corridor collapse trigger feasibility reversion and logic backflow. Reaction pathways can be undone through geometric inversion, and logic propagation can reverse via imprint unraveling. The manuscript explains how substrates host reversal zones and coherence drains, reframing collapse as a substrate-native undo mechanism. Engineered substrates can suppress feasibility encoding and enable logic inversion through corridor collapse.
