  negotiation: >-
    A client discovers the versions Kizik serves from /.well-known/ucp, which returns a
    supported_versions map of version to version-pinned discovery URL. The version actually applied is
    echoed on every response as x-shopify-ucp-mcp-api-version.
  response_header: x-shopify-ucp-mcp-api-version
  discovery: https://kizik.com/.well-known/ucp
  note: >-
    Two concurrent protocol versions are served, which is a real overlap window rather than a hard cutover.
capability_versioning:
  detail: >-
    Individual capabilities carry their own version and a requires.protocol.min floor. For example
    dev.ucp.shopping.fulfillment and dev.ucp.shopping.discount both declare requires.protocol.min
    2026-04-08, so they are unavailable to a client pinned to 2026-01-23.

  deprecation_header: false
  rfc8594: false
  note: >-
    No deprecation policy, sunset schedule, Sunset/Deprecation response headers or end-of-life notice is
    published for either UCP version on any Kizik host. The dated version scheme implies rotation but
    nothing states how long 2026-01-23 remains callable. No Deprecation pointer is emitted.
status_page:
  published: false
  note: >-
    Kizik operates no status page of its own. The underlying platform publishes status at
    status.shopify.com, but that is Shopify's page reporting Shopify's availability, not a Kizik
    commitment, so no StatusPage pointer is emitted on Kizik's behalf.
sla:
  published: false
changelog:
  published: false
  note: >-
    Kizik publishes no dated API changelog. Protocol changes arrive through the UCP version map, and the
    upstream protocol changelog lives at https://ucp.dev, which Kizik does not author. No ChangeLog
    pointer is emitted.
