Number watch (?domain=): every phone number a directory listing or an AI answer gives for the business that is not one of its own, attributed: invented (dummy pattern), old_number (its site published it before), sibling (another business on the licence), another_business (YellowPages lists it under a different name), listed_as_this, unknown. Read daily for businesses on an active licence. Public: counts and classes; the licence holder gets the numbers, where each is printed and whose it is. Signed (crawlcheck-business-number-watch).
