No-fibs: the AI suggests part numbers from the supplier's real catalog. Links open the real product page whenever the supplier has a direct one; when they don't (Digi-Key and Home Depot product URLs need a page slug), the link opens an honest search for that exact part number and is labeled "Find this part". Part photos only appear when the app could actually fetch and re-host them — otherwise you get the category icon, never a broken image. When the app checks a part page and the supplier's site answers without that part, the link becomes an honest search instead of a broken "product page". Every part row has an Edit button — if a link opens the wrong page, paste the correct product URL yourself and the row is marked as human-edited. Always confirm a part is in stock and the right spec before ordering.
