https://datatracker.ietf.org/doc/draft-ietf-v6ops-ipv6-deployment/ made an effort to define what IPv6-only is.  I think it did a fine job.  If we can agree on what IPv6-only is, we can also agree on what Dual-Stack is (any IPv6 deployment that is not IPv6-only is Dual-Stack).  So it would be great if you folks can take a look at Section 1.1 and see if you agree.

Sorry, but that was deliberate. I don’t think we have a lot of clarity as to what we mean by dual stack. That leads, as you rightly pointed out, to circular discussions.

No hats.

With respect, I tend to think this question muddies the waters. You said it's a v6-only network. It's v6-only. If it has an access mechanism (NAT64) to enable someone else to communicate with it using a different technology, that isn't inherent in the network, and doesn't change the nature of the network.
