  PBS Biotech publishes no numeric rate limits. Its store's agent instructions state that the UCP/MCP
  endpoint is rate-limited per IP and that agents should back off on HTTP 429, but give no request
  count, window, or burst allowance, and no rate-limit response headers are documented. limit_count is
  therefore an honest zero: the SIGNAL is documented, the LIMIT is not. No rate limit could be observed
  on the live endpoint because the probe stayed well below any plausible ceiling.
