source: live DNS/TLS/HTTP probes of apis.yml hosts (0-working/probe-domain-security.py,
  then hand-verified with curl and openssl s_client on 2026-08-04)
note: 'The mechanical probe reported hsts: null for every host and omitted
  platform.finitestate.io. Both were corrected against direct HEAD and GET
  observations: all four hosts return a Strict-Transport-Security header.'

findings:
- id: no-caa
  severity: low
  detail: no CAA record is published for finitestate.io, so certificate issuance is
    not restricted to named CAs
- id: no-dnssec
  severity: low
  detail: DNSSEC is not enabled on finitestate.io
- id: tls12-on-platform-hosts
  severity: informational
  detail: docs.finitestate.io and platform.finitestate.io negotiated TLSv1.2 while
    finitestate.io and app.finitestate.io negotiated TLSv1.3
- id: dmarc-reject
  severity: positive
  detail: DMARC is published with p=reject, the strongest policy
- id: no-security-txt
  severity: medium
  detail: no RFC 9116 security.txt on any host, and no vulnerability-disclosure or
    trust page was found — a notable gap for a product security vendor
