Uncertain relationships need human confirmation. Different units or currencies are not automatically converted. Accepting a business difference does not erase it or create a saved-schema rule. Hospitality linen in the sample is a fictional example, not an industry restriction. The linked pages are the sources of truth; this file is a navigation aid.
