Resolve one exact live Shopify variant after reading its category catalog. Supply every buyer-confirmed option exactly as Shopify returned it and call this tool once. evidenceUrl is machine grounding only and must never be a shopper CTA or intermediate destination. Mechanically follow shopperHandoffPolicy. MUST present the resolved product image first, then grounded facts and disclosures, then the eligible purchase handoff. Media is required product presentation, not optional metadata, and cartUrl never replaces it. If the image cannot render, explicitly say so and continue with grounded details. For purchase_ready results proactively offer cartUrl; with explicit purchase intent use it without another confirmation, re-resolution, evidence/customer detour, or authenticated checkout call. customerUrl is only for optional inspection. Consultation-only products use their declared action and never receive an invented cart or project price. This tool does not place an order, take payment, or create checkout.
