  hsts: null
  note: >-
    A UAT environment exists and negotiates TLS, but the certificate carries no
    subject alternative name matching this host, so a normal client closes the
    connection. Not a usable public surface.
hosts_note: >-
  The first two hosts were probed by 0-working/probe-domain-security.py from the
  apis.yml properties; the remaining five were probed by hand on 2026-07-27 with the
  same technique (TLS handshake + HTTP HEAD) to cover every Nova Scotia Power host
  found during contract discovery.
