versioning:
  scheme: semver on the product; protocol versions negotiated per surface
  current:
    agent_card_version: 0.1.0
    mcp_server_version: 0.1.0
    a2a_protocol_version: '0.3 (top-level); supportedInterfaces[] also declares 1.0 on the same URL'
    mcp_protocol_version: '2025-06-18 (negotiated at initialize)'
    data_policy_version: '2026-09-11'
    signing_key_id: b612-a2a-2026-09
  mechanism: >-
    No version segment in the A2A path other than /a2a/v1 and no version header. The A2A endpoint advertises
    both protocol revisions 1.0 and 0.3 on one URL, so a client of either revision is served without a
    separate path. The signing key id is month-stamped, which implies a rotation scheme, but no rotation
    policy is published.

  sunset_header: false
  deprecation_header: false
  notes: No deprecation policy, sunset commitment or RFC 8594 headers are published. The legacy /.well-known/agent.json path is still served alongside the canonical card.
changelog:
  url: null
  notes: None published. The data policy carries a version date (2026-09-11) but no change history.

  cancellation: 'Monthly plans can be cancelled at any time; no cancellation fee; notice by e-mail or LINE by month-end for the following month (company page).'
  post_cancellation_data: 'Usage records in terms §8 are not deleted automatically on trial end or cancellation, except those with a stated retention period; deletion on request via LINE or info@hakuto-0209.com.'
