note: 'Synse Server documents no rate limits. There is no limit, no window, no burst, no X-RateLimit-*/RateLimit-*
  response header, no Retry-After and no 429 anywhere in the v3 API reference — the documented error codes
  are 400, 404, 405 and 500 only. This is consistent with the deployment model: Synse is self-hosted software
  the operator runs on their own infrastructure, so throughput is bounded by that deployment rather than
  by a vendor quota. The related runtime controls the docs DO publish are a plugin request timeout and
  a reading-cache TTL, both operator-configured, not caller-facing. An honest zero, not a gap in the probe.'
related_controls:
- name: plugin backoff
  detail: A plugin that fails a request is marked inactive so later requests do not block on it, and reconnection
    is retried in a background task with exponential backoff.
  docs: https://synse.readthedocs.io/en/latest/server/user/advanced/
- name: reading cache TTL
  detail: Transaction ids and cached readings expire after a configurable TTL.
