Voyager 1 and Voyager 2 recorded a series of unexpected plasma, magnetic field, and particle‑density anomalies during their crossings of the heliopause. These include abrupt density increases, persistent plasma wave activity, magnetic field rotations, and asymmetric boundary behavior that remain difficult to reconcile within standard heliophysics models. This paper interprets these anomalies through the MID/QC substrate framework, proposing that the heliopause functions as a coherence surface: a tension‑gradient boundary in the underlying substrate where coherence changes sharply and ridge‑like behavior emerges. The observed Voyager signatures align with predicted properties of substrate coherence surfaces, including tension discontinuities, coherence gradients, and boundary‑layer oscillations. This reinterpretation provides early empirical support for MID/QC substrate physics and demonstrates how coherence‑surface dynamics can naturally explain heliopause anomalies without invoking additional mechanisms.
