KiField Framework: Reinterpreting Gravity and Reorganizing the Dark Sector through the Vacuum State Variable K

We present KiField Vacuum State Dynamics (KVSD), a framework in which the vacuum has aphysical state and response structure represented macroscopically by a scalar state variable K(x).The variable organizes matter proper time, local distance measurement, rest-energy scale, and therefractive index and propagation time of massless signals.This paper combines this measurement structure with the stationary-action principle of theK-vacuum, and reorganizes gravity, dark-matter-like phenomena, and dark-energy-like phenomenawithin a single minimal grammar. In the solar-system weak-field limit, we show that the linearK-response produced by baryonic sources can be matched to the leading coefficients of Newtoniangravity, Shapiro delay, and light deflection. On galactic and large-scale-structure scales, we discusshow the inhomogeneous K-contribution of the early universe may organize into a pre-existing K-webconsisting of void bulks, walls, filaments, and nodes, and how this pre-existing K-web may bere-identified as outer galactic K-halos through baryonic anchoring. In the cosmic mean background,we show how the state-offset contribution and long-period restoration of the homogeneous background value of Kmay be interpreted as dark-energy-like domain expansion.In this way, dark-matter-like effects and dark-energy-like effects are reorganized not as separateindependent components, but as observational projections of the same K-vacuum state dynamicsdifferentiated into an inhomogeneous structure mode and a homogeneous background mode. Thepurpose of this paper is not to complete precision cosmological fitting. It is to establish a minimalaction–measurement–K-web grammar for discussing solar-system weak-field matching, additionalouter-galaxy gravitational response, a void-driven K-web, and homogeneous-background domainexpansion within one K-state dynamics.
