  We go a step further in the search for a consistent and realistic
supergravity model of large-field inflation by building a class of models with
the following features: during slow-roll, all the scalar fields other than the
inflaton are frozen by large inflaton-dependent masses or removed from the
spectrum; at the end of inflation, supersymmetry is spontaneously broken with
naturally vanishing classical vacuum energy. We achieve this by combining some
geometrical properties of the Kaehler potential with the consistent use of a
single nilpotent chiral superfield, in one-to-one correspondence with the
supersymmetry-breaking direction in field space at the vacuum.
