notes: >-
  Live probes on 2026-07-12. Email authentication is strong on the apex domain
  (SPF present, DMARC at p=reject/100%). No CAA records published and DNSSEC not
  enabled (AD flag absent; NS on AWS Route 53). HSTS is enforced on the developer
  portal but was not observed on api.bigchange.com or the apex www host at probe
  time.
