The cited work includes a spherical benchmark associated with the lens galaxy ESO 325-G004. Such a calculation can connect an assumed radial gravitational response to a predicted deflection, but it is not yet the same as a complete reconstruction of the observed lens with all relevant metric degrees of freedom and source uncertainties.

Rotation curves mainly constrain the gravitational behavior governing slowly moving matter. Lensing depends on the combination of metric potentials encountered along the light path. A successful dynamical acceleration law therefore cannot simply be declared a successful lensing theory without establishing that connection.

The source review scope audit explicitly identifies the need to recover the relevant potentials and determine whether gravitational slip is present. Gravitational slip refers here to a difference between the two potentials used in the weak-field description. Its treatment affects whether a matter-based inference transfers consistently to light deflection.

An observational test must also specify the stellar and gas source, lens and source distances, geometrical assumptions, and uncertainties in the reconstructed image. A ring size alone does not exhaust the information available in a strong lens, and a spherical approximation can conceal effects of shape and environment.

The immediate research milestone is a clearly defined requirement for the next calculation. The same completed model should predict both the galaxy’s dynamics and its lensing observables with a documented source prescription. Agreement would strengthen the case for a unified account; disagreement would identify where the cited construction needs revision or fails. The existing benchmark should be reported at that limited stage, without claiming that gravitational lensing has already been comprehensively explained.
