result: >-
  No genuine /.well-known/ discovery documents were found. The api and docs hosts
  return real 404s; the marketing/platform hosts return a 200 text/html SPA
  catch-all for every path (soft-404), so none represent a real security.txt,
  OIDC, OAuth-authorization-server, api-catalog or ai-plugin document.
