note: >-
  3vjia publishes NO rate limits. Not one of the 528 documentation records mentions a request rate,
  quota, burst, concurrency cap or throttling behaviour, and no live response from
  open-gateway.3vjia.com carries an X-RateLimit-*, RateLimit-* or Retry-After header. An honest zero.

  note: >-
    These are not rate limits, but they are the only published constraints on call volume and an agent
    should treat them as such.
  constraints:
  - constraint: single-token rule
    detail: >-
      Only one access_token is valid per application at a time — requesting a new one invalidates the
      previous one. The docs therefore REQUIRE an enterprise to run a central token service
      ("中控服务") rather than let each system fetch its own. Uncoordinated concurrent token requests
      will knock each other out.

  - constraint: token TTL
    detail: access_token expires after 7200 seconds and must be refreshed on a schedule.
  - constraint: SSO clock skew
    detail: The MD5-signed SSO redirect accepts a ±5 minute timestamp deviation.
  - constraint: quotation key expiry
    detail: >-
      A quotation result token expires (errorCode 609007) — a poll loop must not run indefinitely.
      The duration is not published.
  - constraint: authorization code TTL
    detail: The authorize operation's temporary code is valid for ten minutes (十分钟内有效).
