Maybe I didn't look it over close enough but every outside layer was stone or some stone mixture. Vinyl siding is incredibly common and I'm struggling to understand why house wrap, with rigid foam and osb outside should go with no insulation on the interior.

Figure 8 but with vinyl siding is fine, which has insulation in the cavity. Vinyl is far more forgiving of a siding material than stone, brick, or stucco so I presume the author didn't find it worth mentioning. Vinyl has lots of gaps so air and water vapor travel freely and it mounts with just nails so there's no brackets causing thermal breaks, so there's almost no way installing vinyl siding can compromise liquid water and vapor management. OTOH it's trivial to install synthetic stucco and trap water somewhere, causing rot and building destruction.
