  We derive a sufficient set of conditions on the Euclidean boundary theory in
dS/CFT for it to predict classical, Lorentzian bulk evolution at large spatial
volumes. Our derivation makes use of a canonical transformation to express the
bulk wave function at large volume in terms of the sources of the dual
partition function. This enables a sharper formulation of dS/CFT. The
conditions under which the boundary theory predicts classical bulk evolution
are stronger than the criteria usually employed in quantum cosmology. We
illustrate this in a homogeneous isotropic minisuperspace model of gravity
coupled to a scalar field in which we identify the ensemble of classical
histories explicitly.
