They are recorded as Arlettie's agent surface because they are served from hosts Arlettie controls (custom domain lesechappees.arlettie.com; canonical store arlettie-les-echapees.myshopify.com), they are advertised by Arlettie's own /robots.txt, /llms.txt and /agents.md, and they return Arlettie's catalog, cart, checkout and policy data. GraphQL shop.name confirms the merchant as "Arlettie Les échappées" and merchant_origin in the UCP profile is lesechappees.arlettie.com.
