  Every conformance below is read from a document Virtuix's own hosts actually served on 2026-09-04,
  not from a marketing claim. The documents are issued by the Shopify platform for Virtuix's store;
  the conformance is real for anyone calling virtuix.com, and the provenance is stated so it is not
  mistaken for a Virtuix-authored implementation.

  evidence: >-
    https://virtuix.com/.well-known/ucp.json — the store's own discovery document declares the
    dev.ucp.shopping service namespace, seven dev.ucp.shopping.* capabilities and the
    dev.shopify.catalog extension, and the MCP tool descriptions name the UCP capability they
    implement ("Response conforms to the UCP catalog search capability (dev.ucp.shopping.catalog.search)").
    This is a contract-level declaration, not a prose claim on a marketing page.
