The definition
- Definition
- The cart-link list names each platform's documented cart link and the catalog fields that build it: Shopify's cart permalink (/cart/<variant id>:<quantity>) and WooCommerce's ?add-to-cart=<product id>. UCP's permalink capability is a profile declaring dev.ucp.shopping.permalink whose config.endpoint is an absolute https URL with no query, fragment or trailing slash, to which an agent appends the items to start a purchase.
- Passes when
- The platform is identified, and the fields its cart link needs are read from at least one catalogue product; or the UCP profile declares the permalink capability with a well-formed endpoint. The probe follows neither. Or a route of R2.3 or R2.4 is met. A route in lists.routes listed for this rung, or for a higher rung of the same dimension, meets it; the result names the route.
