The Ghidan informational framework introduces a scalar throughput field χ(x) representing the fraction of spacetime’s information-propagation capacity available at a given location. This field obeys the Capacity-Conservation Law (CCL) χ² + L = 1, where L represents informational load generated by localized energy density. Directly quantizing χ while preserving this constraint is nontrivial, because χ and L are not independent variables: fixing one determines the other. In this article we present a formulation that preserves the CCL exactly by introducing a new scalar field θ(x) such that χ = cosθ and L = sin²θ. This parametrization ensures that capacity conservation holds identically at all spacetime points as a trigonometric identity, requiring no constraint enforcement at the quantum level. Quantizing θ then produces quantum fluctuations in informational throughput while maintaining the fundamental conservation structure. This framework provides a consistent route toward a quantum description of spacetime informational capacity.
