versioning:
  scheme: URL path (+ sign_version parameter on the Open API)
  current: Open API v2 (推荐/recommended)
  legacy: Open API v1 (kept online for existing integrations; served at
    /api/v1|/api/v2 with the weaker MD5 query-string signature — the docs
    themselves advise migrating to v2 because "V1 版本的接口存在安全隐患")
  auth_generation_change: ServiceGo switched its signature algorithm from SHA-1
    to SHA-256 for tenants created on or after 2021-06-03 (both documented).

deprecation:
  policy_url: null
  sunset_header: false
  note: >-
    No formal deprecation policy or RFC 8594 Sunset/Deprecation header support
    is published. v1 is de-facto legacy ("旧版 API 文档") but no retirement
    date is announced. No Deprecation pointer emitted.
sla:
  url: https://www.udesk.cn/service_agreement.html
  uptime_target: "99.9%"
  detail: >-
    Public SLA commits to 99.9% monthly service availability per tenant
    (max ~43.2 minutes unavailable per month), with service-credit
    compensation terms when missed.
status_page: null
status_page_note: No public status page was found on udesk.cn (no status.udesk.cn);
  availability monitoring is described as internal (self-built "北斗" monitoring)
  on https://www.udesk.cn/product_safety_features.html. No StatusPage pointer emitted.
changelog:
  url: null
  note: >-
    No public dated API changelog was found. The www.udesk.cn/ucm/ "update"
    section is a news/content hub (verified /ucm/update/65980 is a partnership
    press article), so no ChangeLog pointer is emitted.
