A Deterministic Pilot Medium: Bell Path Selection and Autonomous Material Records

This paper constructs a finite deterministic hybrid pilot medium whose ordinary configuration histories converge to the minimal Bell jump process on a fixed finite graph and physical-time horizon. Canonical bond currents drive conservative packet export. An independently prepared spatial gas generates an approximation to marked Poisson contact histories, finite opposite-packet recombination suppresses surplus traffic, and carrier-population tracking produces the residence-weight denominator. The combined comparison controls complete tagged paths, including nodes, current reversals and null intervals. For a fixed compiled clock and quantitatively calibrated initialization, explicit resource scales yield an O(N^(-1/70)) error bound. An autonomous material Hamiltonian includes source, fuel, pending and loss states, physical copies, reset receivers, an inaccessible reference and noncommuting continuation. Monomial copy boundaries are crossed exactly once on the clock’s first pass, establishing faithful records of actual sampled configurations. The result is a controlled effective realization under the declared P1–P4 interaction and preparation assumptions. Exact finite-resource Bell dynamics and a smooth Hamiltonian realization of the entire hybrid source are not established. This Version 2 preprint presents the proofs and appendices as a self-contained companion to the monograph.
