Three stages retain source objects, apply declared measurements and operations, and compare whole fields. Six examples show genealogy, lists, New Testament display, one-pass decimal inverse, calendar Keys, and Covenant carriers. Shared topology does not imply equal weights; equal totals do not imply equal interiors; generated maps are not a universal date conversion.</desc>',
