method: probed
source: live DNS/TLS/HTTP probes of the apis.yml website host and the corporate mail domain
note: >-
  The company's only live web host, descnc-china.com, serves plain HTTP and does not
  answer on port 443 at all — https://descnc-china.com/ returns a connection failure,
  not a certificate error. The AIMACH-branded domain desu-aimach.com carries MX and
  SPF records (Alibaba Cloud corporate mail) but no A record, so it is a mail-only
  domain. CAA absence was re-confirmed directly against 8.8.8.8 after the first probe
  timed out.
