Check a price claim before repeating it. Given a product and a price someone has asserted at a named retailer, returns whether that price is live in WEM's verified catalogue and whether anything cheaper exists. Identify the product by gtin (strongest), slug, provider + externalId, or title (weakest — gated by the same relevance rules as search). Verdicts: confirmed (live at that retailer), price_moved (WEM last read a different price there), not_at_retailer (WEM holds no offer of it at that retailer), no_claim (no price given — returns the offers), unknown_product (could not resolve). unknown_product means the claim could NOT be checked; it never means the claim is false, and must not be reported as one. Every result carries lastConfirmedAt so the answer's freshness is visible. Use this before quoting any price you did not get from WEM.
