note: >-
  MicroByre is out of business and its web surface is gone, but the registration is
  still held and still carries live mail DNS. Recorded because the DNS answers are
  real observations; no DomainSecurity pointer is wired into apis.yml, because there
  is no served host for that pointer to assert.

    resolves: false
    tls_version: null
    hsts: null
    error: >-
      NOERROR with no A/AAAA answer — the apex publishes no address record, so no
      TLS connection is possible.

      Dangling CNAME — the CloudFront distribution dw7qr6qh3v5bt.cloudfront.net
      returns NOERROR with no answer, i.e. the distribution has been deleted or
      disabled.

  - The company website is unreachable; DNS resolves no address for the apex or www.
  - Mail is still delivered (Proton Mail MX, SPF and DMARC quarantine present).
  - No DNSSEC and no CAA records are published.

    www.microbyre.com is a dangling CNAME at a deleted CloudFront distribution — a
    subdomain-takeover shape worth flagging to whoever still holds the registration.
