Andrew,

I can't answer your question. (And I'm very unsure any subscriber can)

But I struggled some times ago about the general question "what data are covered by an ARC seal?"
I took a message I receive and which are marked as "arc=pass"

$ openarc -v -v -v -t /path/to/msg

-> say also (and expected) arc=pass

Now I change one random character in the message body and the command above say "arc=fail"

I thought, an ARC seal cover only added Authentication-Results: Header, but this test show the opposite.
I read RFC 8617 but I'm still unclear about how ARC really works.

Could you suggest more documentation?
