Paper T16B: Field-Language License via EML–B When Maxwell-like Effective Descriptions Are Operationally Justified in the Ignited Regime

We ask when the occupied Holosphere contact network supports a useful linear field description.Starting from the reciprocal contact Hamiltonian used in current Papers 122BE and T16A, wederive exact discrete source balance, loop induction, field response, and field–surface energyexchange. The loop field obeys a sourced second-order wave equation on the contact complex.A matched-reference construction then separates the response to a later trigger from activityalready present. Smooth dependence on that trigger gives a preparation-dependent linearresponse operator; erasure of preparation memory is not required. EML–B tests signed fieldscaling, addition of two drive shapes, reversal of drive sign, and preparation sensitivity separately.On the 917-site FCC host, an unprimed trigger of amplitude 0.0125 has doubling, additivityand reversal errors of 2.58%, 1.12% and 5.16%, respectively, while an earlier primer changesthe matched response by 56.59%. Step halving changes refined response vectors by less than0.0086%. The quadratic field-response measure is identified as perturbation storage, with itsbackground cross term retained when calculating actual energy change. These results establishdiscrete field structure and a tested linear-response window within the stated Holosphere law.The title’s Maxwell-like comparison refers to the displayed incidence equations; a continuumelectromagnetic identification requires further physical correspondence.
