Supplier map. With domain=: for each of the business's listings, which source it was most likely fed from - the Business Profile, the site, or an upstream it shares with another directory - inferred from distinctive values (a value shared by two sources while a third states that field differently: a legal-form name, a deep-link website, the same wrong ZIP), with the evidence, a confidence, and what the directory itself declares (Bing names its ratings source). Public answers compare with the site only; the licence holder or owner adds the Business Profile. With no domain: the network map, counts per directory and per shared-upstream pair across every business read so far, no business named. Signed (crawlcheck-business-suppliers).
