note: >-
  Rhone publishes no API versioning policy, no deprecation policy and no status page of its own.
  What is observable is the UCP protocol version the store negotiates, which is date-based and
  advertises the previous version alongside the current one.
versioning:
  scheme: date-based (UCP protocol version)
  current: '2026-04-08'
  also_supported: ['2026-01-23']
  negotiation: >-
    /.well-known/ucp lists supported_versions with a per-version discovery URL; the live MCP
    endpoint echoes the served version in the x-shopify-ucp-mcp-api-version response header.

deprecation_policy:
  published: false
  sunset_header: not observed
  deprecation_header: not observed
  note: >-
    No RFC 8594 Sunset/Deprecation headers observed on the MCP endpoint. The only deprecation
    signal is that a superseded UCP version (2026-01-23) is still listed as supported.
status_page:
  published: false
  note: >-
    Rhone operates no status page. The underlying platform status is Shopify's
    (https://www.shopifystatus.com), which is not a Rhone-published surface, so no StatusPage
    pointer is emitted.
