source: live probe of /.well-known/ across Avalara hosts
notes: >-
  Probed the discovery surface on the four primary Avalara hosts. Only the
  identity host publishes a discovery document: identity.avalara.com serves a
  full OpenID Connect discovery document (IdentityServer). The AvaTax/API hosts
  return 401 (auth required) for all paths; the developer portal returns 404
  (SPA). Absence is recorded data.
