V.P122 — a_0 from H_0 Tension

a_0 = c*H_0*iota_tau/2 evaluated at low-redshift (local) H_0=73.0 gives 0.9% from MOND; at CMB H_0=67.4 gives -6.9%. Galaxy rotation curves probe local H_0. The H_0 tension structurally manifests as uncertainty in the galactic acceleration scale. Falsifiable: BTFR normalization A should shift as H_0 tension resolves.
