Is this wrong? We were under the impression that tyvek is to be wrapped over the tops of the walls and fully taped at all its seams to ensure a tight seal. This is many different locations around the exterior top of walls of the house just under the soffit at the top of the stoned exterior walls. The masons installed the tyvek as they were stoning the house. This is exactly how it was installed and intended to be left.
