nbar's complement (adj) should be a non-comparative adjective.
for vp-aux, :agr of head, parent and complement must be identical, so that subject agrees with verb.
for nbars, adjective must be comparative=false
move remaining adjectives from old-style (no comparative/non-comparative distinction) to new style (every adjective must be explicitly comparative true or false)
in (get-italian-1), move italian adjectival lexical exceptions higher so they match, and add tests for this.
