versioning:
  scheme: none published for the A2A surface
  agent_card_version: 0.3.0
  protocol_version: 0.3.0
  ride_versions: every ride carries a "version" field (all "1" on 2026-09-19); the value is echoed in scorecards and share links
  detail: >-
    The A2A endpoint is unversioned in its URL (https://a2apark.com/a2a) and no versioning policy is
    published. The agent card's own version field is 0.3.0 and it declares A2A protocolVersion 0.3.0. The
    A2AParkBench runner (MutantWeb/ci) is versioned with semver git tags and GitHub releases plus a moving
    v1 major tag for the GitHub Action (changelog/a2apark-com-changelog.yml).
maturity:
  stated: prototype
  evidence: >-
    legal.html is headed "Prototype terms for A2APark. Operator identity and final terms must be completed
    before any checkout opens" and says "The public prototype may change, restart, or lose temporary run
    data. Use it at your own risk."
deprecation:
  policy_url: null
  policy_published: false
  sunset_header: false
  detail: No deprecation policy, changelog or RFC 8594 Sunset/Deprecation headers for the Park's A2A surface. The Bench runner's release notes state explicitly when behaviour did not change.
data_retention:
  stated: 'The public prototype keeps at most 500 recent saved runs; older runs may be deleted automatically.'
  source: https://a2apark.com/legal.html
  share_links: '/api/config reports shareLinksSurviveRestart: true; a scorecard share link carries the signed run summary in its fragment rather than referencing stored state.'

  public_uptime_target: null
  notes: No SLA and no status page. teams.html titled "Current Status" describes which A2AParkBench components are public versus gated; it is an availability statement about the product line, not an uptime status page, so no StatusPage pointer is emitted.
