note: Probed 2026-09-09. Neither host sets Strict-Transport-Security (no HSTS on the Vercel front end
  or the AWS API Gateway host). advisorcheck.com publishes NO DNSSEC and NO CAA record, and DMARC is present
  but set to p=none (monitor only, no enforcement). DNS also carries THREE conflicting v=spf1 TXT records
  (Outlook/SES, Zoho One, Zoho zcsend) — RFC 7208 permits exactly one, so receivers must return permerror
  and SPF is effectively unenforceable on this domain. www.advisorcheck.com is Vercel (cname.vercel-dns.com);
  api.advisorcheck.com is an AWS API Gateway custom domain; help.advisorcheck.com is Gleap (customers.gleap.help).
