  No rate limits are published. Read the full TruContact TCS spec — all nine operations,
  every parameter, both error schemas and all 179 example error_ids — and there is no 429
  response, no X-RateLimit-*/RateLimit-* header, no Retry-After, and no throttling language
  in info.description or the tag copy. This is consistent with the deployment model: the
  AS/VS runs inside the carrier's own network against a per-carrier capacity agreement, so
  throttling is a contract term rather than a runtime signal. An agent calling this API has
  no way to learn its budget from the contract, which is the finding.
