source: live probes of /.well-known/* on viso.ai hosts
notes: >-
  viso.ai serves a SiteGround bot-challenge (HTTP 202 "sg-captcha: challenge"
  meta-refresh) for every path including /.well-known/*, so no machine-readable
  well-known document could be confirmed there. now.viso.ai (the Viso Now app)
  is a client-rendered SPA that returns the app HTML shell (200 text/html) for
  every unknown path, so /.well-known/* there are SPA fallbacks, not real
  documents. No genuine security.txt, openid-configuration, oauth-authorization-server,
  api-catalog, or ai-plugin.json was found. Absence recorded as honest data.
