  Vanderhall documents no rate limits, and none were observable. No X-RateLimit-*, RateLimit-* or
  Retry-After header appeared on any probed response from any Vanderhall host, and no 429 was
  elicited. The only machine-readable surface is an OAuth-gated MCP endpoint that rejects anonymous
  calls before any quota would be consumed, so an unauthenticated probe cannot establish whether
  limits exist behind the wall. An honest zero: limits are undocumented and unsignalled, which is
  itself the finding an agent needs — there is no runtime backpressure signal to react to.
