This note presents the short-range fifth-force phenomenology of a benchmark branch whose reduced gravity sector is that of a massive Brans–Dicke scalar with fixed parameter ₁₃=3/2. The branch predicts a universal Yukawa coupling ₘ₊=1/6 and an interaction range C=M₋/ (8. 57\, R²), defining a one-parameter horizontal trajectory in the standard Yukawa exclusion plane. The purpose of the note is limited: it records the benchmark prediction in standard Yukawa language, explains why macroscopic Solar-System deviations are exponentially suppressed by the short range of the scalar, and gives a preliminary comparison to the Lee et al. (2020) torsion-balance contour near R1\, TeV.
