/-- MB8: legacy CEV/process bridge. If an external theory certifies preservation
    of a human value-update process, that suffices for correction integrity
    without knowing a final fixed point. The main certification path does not
    rely on this opaque route; it uses grounding, correction, and adversarial
    layer evidence directly. -/
