  Results of probing the /.well-known/ discovery surface for the Braintrust
  (usebraintrust.com) web hosts. Braintrust publishes no API base host; the
  probed hosts are the marketing site and the marketplace app. Status is the
  HTTP code observed at fetch time. No /.well-known/ document returned a real
  payload: www answers 404 for every path, and app.usebraintrust.com answers
  301 (redirect to a trailing-slash SPA route) rather than serving a document.
  The site does publish /llms.txt (saved at llms/usebraintrust-llms.txt).
