  No published rate limits, quotas, throttling policy, or rate-limit response headers were found for
  any GE Vernova Electrification Software API. This is consistent with the deployment model: the
  Proficy REST services run on the customer's own servers, so throughput is bounded by the
  installation rather than by a vendor quota. What IS published is a set of result-size and
  licensing ceilings, recorded below because they are the nearest thing to a documented limit an
  integrator will hit. No 429 is documented — the published status contract stops at 500.

      explicitly to stop large payloads transiting the network; callers that need FULL must ask.
