method: probed
source: live GET of /.well-known/* on every Sygnum host named in apis.yml and in the developer-portal bundle
note: >-
  www.sygnum.com sits behind a Cloudflare bot challenge that answers 403 to browser-style
  User-Agents; a plain probe User-Agent is served normally, which is how the RFC 9116
  security.txt below was read. developer.sygnum.com is a client-side SPA whose origin
  answers 403 to non-browser agents and returns the same 1,081-byte HTML shell (HTTP 200)
  to browser agents for every path — none of its /.well-known/* 200s is a real document,
  so nothing from that host is recorded as a hit.
