    A client reads supported_versions from the merchant profile and selects one. Three concurrent
    versions are advertised, so version selection is a real, machine-readable operation rather than
    a docs claim.

  note: >-
    No deprecation or sunset policy is published by UrbanStems, and no RFC 8594 Deprecation or Sunset
    header was returned on any probed response. The dated-version ladder implies older versions are
    eventually retired, but no removal date, notice period or migration guide is stated. No
    Deprecation pointer is claimed.

    checked: '2026-09-02'
  note: >-
    No first-party status page. Storefront and MCP availability ride on Shopify's platform status,
    which UrbanStems does not link from any of its own agent-facing documents. No StatusPage pointer
    is claimed.

  note: No uptime or latency commitment is published for the agent surface.

changelog:
  published: false
  note: >-
    No API changelog or release notes. Protocol change is legible only through the dated
    supported_versions list in /.well-known/ucp. No ChangeLog pointer is claimed.

deprecated_operations: []
deprecated_operations_note: >-
  No tool in the live tools/list response is marked deprecated, and the contract carries no
  deprecation annotation vocabulary.
