versioning:
  scheme: unversioned-mcp
  detail: >-
    The MCP endpoint (https://mcp.segmentstream.com/mcp) is served without a
    version segment; tools evolve continuously. The undocumented GraphQL surface
    at api.segmentstream.com is path-versioned at /v1/, but nothing about it is
    published. There is no public REST version scheme.
deprecation:
  policy_url: null
  sunset_header: unknown
  detail: >-
    No published deprecation policy and no RFC 8594 Sunset/Deprecation header
    support found. This is a live gap rather than a theoretical one: the May
    2026 rename of the Visit Scoring attribution model to Predictive Attribution
    changed a model name that agents and integrations reference, and it shipped
    as a blog post with no deprecation notice, sunset date, or migration path.
    No Deprecation pointer is emitted.
changelog:
  url: https://segmentstream.com/blog/product-updates
  scheme: dated-blog-posts
  artifact: changelog/segmentstream-changelog.yml
  detail: >-
    Product changes are announced as dated marketing-blog posts. There is no
    developer changelog, no version numbers, and no record of MCP tool
    additions, renames or removals.
sla:
  url: null
  uptime_target: null
  detail: >-
    No published uptime target. The pricing page lists "Priority SLA" as an
    Enterprise-tier feature, so an SLA exists contractually for that tier but
    its terms are not published.
