This work develops the theoretical basis for an auxiliary informational domain in which structured information exists without energetic exchange yet remains consistent with the conservation and symmetry principles of special and general relativity. The framework introduces the lugon as the minimal informational unit and defines gating conditions that couple the informational and physical domains while preserving Lorentz invariance and micro-causality. Information—but not energy or matter—propagates on an auxiliary, non-dynamical metric with invariant speed , while all work-carrying fields remain on the physical metric and obey standard relativistic dynamics. For brevity, the null structures of these metrics are referred to as the g-cone and h-cone, and causal behavior defined with respect to each as g-causal and h-causal. The informational field is a constrained scalar with an action independent of , yielding identically vanishing Hilbert stress–energy ; it performs no work and does not curve spacetime. Interactions are derivative, universal, and strictly confined to a device domain through a gate . Shift symmetry of , a Weyl symmetry on , and locality together enforce radiative sequestering, preventing Lorentz-violating or long-range couplings outside . Micro-causality holds in both cones, and a global time function orders g- and h-causal processes, excluding causal loops. Thermodynamic consistency follows from Landauer and Sagawa–Ueda bounds, closing Maxwell-demon loopholes. A domain-local sampler reproduces Born-rule statistics with flat marginals, preserving the no-signaling theorem. Three decisive experimental paths are identified: (1) Internal measurement of and device-internal signatures—a sub-permille Bell-visibility anisotropy and syndrome “ridge” structure in QEC arrays;(2) Gravitational probes enabling tiny but testable graviton mass via GW dispersion (ET/CE, LISA, PTAs) and photon-mass bounds via deep-space magnetostatics;(3) A falsification matrix covering off-device signaling, Lorentz leakage, GW inconsistencies, and EFT breakdown. An energy-free horizon information membrane aligns with the Page-curve/”islands” picture of black-hole thermodynamics without altering established laws. The result is a two-cone, sequestered effective field theory that preserves tested SR/GR predictions while making concrete, falsifiable predictions. It forms the foundational layer of The Lugon Framework, establishing an informational counterpart to the energetic domain and unifying energy, information, and causality as conserved co-variants of physical law. -------------------------------------------------------------------------------- v3 is an updated manuscript version with substantial final revisions throughout the paper. This update includes rewritten and tightened explanatory sections, corrected notation and equation consistency across the manuscript and supporting registry files, refreshed Appendix 0 syntax and definition material, removal of the obsolete internal equation cross-reference appendix in favor of the external Lugon registry system, correction of equation-rendering and symbol-use issues, an updated two-cone/device-domain figure, expanded and corrected citation coverage, restored and added reference support for retrocausal/TSVF, superdeterminism, black-hole thermodynamics, Page-curve/island, gravitational-wave, LISA, and PTA discussions, and final pre-publication cleanup of formatting, terminology, and source consistency.
