    API Evangelist enrichment pass, 2026-08-22. Records the ownership evidence, the agent-surface
    cross-reference and the reversibility warning that belong alongside the spec rather than inside it.

        note: >-
          Vacaville, California is ICON Aircraft's headquarters, and the store's own published
          returns address is 2141 ICON Way, Vacaville, CA 95688. The storefront is judged by what it
          says about itself, not by the host it was fetched from.

        note: >-
          The agent-callable surface is strictly larger than this specification. Every cart,
          checkout and order mutation is MCP-only by design.

      x-agent-guidance: >-
        Prefer the UCP/MCP cart tools. This endpoint is bound to a Shopify session cookie and a
        stateless agent cannot reach an MCP-created cart through it.

    update:
      x-defect: >-
        Observed 2026-08-22: an unknown handle returns HTTP 404 with content-type
        application/json and an HTML body. A client trusting the content-type will throw on parse.
