  live DNS/TLS/HTTP probes of apis.yml + OpenAPI hosts
  (0-working/probe-domain-security.py), corrected and extended by hand on the
  same date: the script's HSTS check reported null for hosts that do serve
  Strict-Transport-Security, and it did not cover the AER-operated Product
  Reference Data host that serves AGL's plans. Both were re-probed with
  `curl -D -` and `dig`, and the observed header values are recorded verbatim.
hosts:
- host: www.agl.com.au

    max-age is 1 day — well below the 31536000 (1 year) that HSTS preload
    submission requires, despite the preload token being present.
