      mechanism: fingerprint
      note: Mutating operations accept a fingerprint query parameter; the request succeeds only when it
        matches the stored resource fingerprint, otherwise a conflict is returned. There is no Idempotency-Key
        header - a retried create duplicates.

      quota_per_project_per_day: 10000
      qps_per_project: 0.25
      window: 100 second sliding window (25 requests)
      exhaustion_status: 403
      exhaustion_reasons:
      - userRateLimitExceeded
      - quotaExceeded
      response_headers: null
      note: No RateLimit-* or Retry-After headers are emitted; 403 + reason is the only runtime signal.

  update:
    x-apievangelist-note: Single production host, no sandbox host. Server-side tagging containers run
      on customer-provisioned infrastructure and are configured, not called, via this API.
