  Rhone's own agent instructions state that the MCP endpoint is rate limited per IP and that agents
  should back off on 429, but publish no number, window, burst or scope. No RateLimit-* or
  Retry-After headers were present on a live 200 from the endpoint on 2026-08-26, so an agent has a
  documented backoff rule and no runtime signal to act on before it is throttled. Honest zero.
