Finds the contradictions on a caller-supplied product page that make a buying agent abort:

Finds the contradictions on a caller-supplied product page that make a buying agent abort: offer price in JSON-LD or Microdata against the prices visible in the text, structured availability against sold-out and add-to-cart signals, JSON-LD against Microdata, variants that cannot be told apart, shipping cost and return period as data or only as prose. Returns a verdict with every contradiction and gap explained. Machine extractability, not price law; no checkout, no outbound request.
