This non-peer-reviewed conceptual preprint / technical note proposes regolith-derived remanent magnetic architecture as a testable interface hypothesis for lunar infrastructure. The manuscript examines whether ferrite-like or ferrimagnetic oxide-rich phases, if available from broader lunar in situ resource utilization (ISRU) processing streams, could be incorporated into regolith-derived structural elements and magnetized after fabrication. The concept does not propose magnetic shielding as a substitute for conventional regolith shielding and does not report experimental validation, demonstrated lunar ferrite production, or operational radiation-shielding performance. Instead, it defines a conceptual framework and experimental roadmap for testing weak, local, passive, and serviceable remanent magnetic interfaces in selected infrastructure zones. Potential local functions include interaction with low-energy charged particles near surfaces, influence on iron-bearing or magnetically susceptible dust fractions, passive support for robotic docking and adhesion, magnetic localization markers, and controlled electromagnetic boundary conditions in selected work zones.
