  Here we consider what happens when we lift a codimension-1 slice of the
celestial sphere to a codimension-1 slice of the bulk spacetime in a manner
that respects our ability to quotient by the null generators of
$\mathcal{I}^\pm$ to get to our codimension-2 hologram. The contour integrals
of the 2D currents for the celestial symmetries lift to the standard boundary
integrals of the 2-form generators for the gauge theory and celestial Ward
identities follow directly from Noether's theorem.
