Chromatic Aberration of Gravitational Light Deflection in Tensor Field Dynamics

In General Relativity, gravitational light deflection is strictly achromatic.Tensor Field Dynamics (TFD), by contrast, models the vacuum as a physical tension field ϕ whose gradients influence light propagation in a field-mechanical manner. From the canonical light law c(ϕ) and the wavelength-dependent sampling of the field, a non-vanishing chromatic aberration of gravitational light deflection follows necessarily. A fully canonically normalised example calculation demonstrates that the deflection difference between blue and red light near the Sun is of the order of 10⁻² mas. The result is parameter-free, field-theoretically enforced, and in principle observable.
