This paper formalizes the second phase of substrate reversal within the MID/QC framework. Reentry zones initiate logic descent and feasibility restoration, while collapse recovery stabilizes substrate fields. Threshold‑native topology governs the reentry arc, enabling engineered stabilization of logic and feasibility. The work defines substrate reversal as a multi‑stage descent and recovery process.
