This paper extends the MID/QC framework into the domain of asteroid‑trajectory anomalies, identifying substrate‑level mechanisms that supplement classical gravitational and thermal models. Coherence gradients, magnetospheric routing, metal‑dependent coupling, decoherence drift, tension‑geometry interactions, and thermally modulated coherence structure introduce small but persistent deviations in orbital paths. These mechanisms provide a unified explanation for long‑standing puzzles such as non‑gravitational accelerations, close‑approach irregularities, and the behavior of interstellar visitors entering the solar substrate. The work offers a disciplined, non‑overclaiming expansion of classical orbital dynamics and establishes a mechanistic foundation for future refinement in asteroid prediction, interstellar‑object interpretation, and planetary‑risk assessment.
