    The probe script records null here because the gRPC-JSON gateway answers
    its HEAD with 405. A direct GET on 2026-08-14 returned
    "strict-transport-security: max-age=31536000; includeSubDomains", so HSTS is
    present on the API host. Corrected by hand; re-running
    0-working/probe-domain-security.py will revert it to null.
