## The starting question

ASD asks whether spatial isotropy must be assumed in a theory built from modern length and time measurement. Its kinematic core is a directional response of true spatial length, called the Length Vector Effect.

## The physical framework

Within ASD, transverse lengths follow L′⊥ = γL⊥ in the specified moving configuration. Gravity is explored through spatial scale and longitudinal structure; magnetic interaction starts from motion-induced changes in Coulomb interaction. Matter is investigated as stable spatial topology.

## Current maturity

The framework contains specified derivations, effective descriptions, candidate microscopic models and open problems. A complete nonlinear particle solution, unified master equation and universal dynamical derivation of Born statistics are not yet established.

## Research access

The current website offers Chinese topic guides, equations, seven open problems and a portable assistant pack. The full monograph and original experimental datasets have not been published here. The on-site researcher currently retrieves source passages; it is not connected to a generative model.
