We evaluate the HAL framework against classical solar system tests. The ADM normalisation Gₑff x Mₑff = GN x MADM ensures that the Schwarzschild radius is identical in HAL and GR, so Mercury perihelion precession (42. 99 arcsec/century) and gravitational light deflection (1. 751 arcsec) are exactly unchanged. Combined with prior binary pulsar results, a structural boundary is established: observables depending on G x M are GR-identical; observables depending on G x J carry epsilon = +alphaₑm = +0. 7297%. HAL is consistent with all gravitational data and makes three independent parameter-free predictions all equal to alphaₑm.
