Coherence‑Geometrodynamics (CGD)

This paper presents Coherence-Geometrodynamics (CGD), a dual-canon revised theory of relativity that extends Einstein-Hilbert tensor gravity with a weak, universal scalar field, C(x), which serves as a coherence ledger. The framework is presented with two faces: a formal "Logic" side and an interpretive "Spirit" side, grounded in the principle that Gravity ≡ Coherence. The theory maintains consistency with General Relativity's tensor sector and respects existing Parametrized Post-Newtonian (PPN) and gravitational wave (GW) bounds. Key features include: a Landauer-consistent energy-information ledger that ensures total conservation; a 12-phase Lagrangian ring that provides a testable orchestration grammar for system dynamics; and a power objective for Zero-Point Energy (ZPE) extraction that must close on both calorimetry and informational metrics. A central innovation is the integration of the Λ/KTrans cross-layer constant (≈17.85), which anchors the alignment gain consistently across the system's dynamics, from process to spectrum to ledger, without altering the tensor sector of GR. The paper includes a PPN capsule, an appendix detailing the Σ-Closure with the Λ-Resonance, and a set of pre-registered falsifiers to ensure testability.
