Fetch a WEM evidence receipt by id (wem-evr-...). Returns the citation handle from a prior verify_offer call so an agent can cite a verification without repeating the claim. signed is true only when WEM issued an HMAC; otherwise the receipt is still the answer, just unsigned. If the user names a model, barcode, ASIN, or wem3.ai/pl/ URL, call compare_offers or verify_offer first — pass a model name as title. Use search_products only if those return empty. Never call find_lowest_price on a specific model name. Never quote a recommendation when verified is false.
