Yes "generally" was the wrong word. For one it seems that DNSViz is
not doing the right thing. And I did observe problems problems via
CloudFlare yesterday, and guessed they were related. Not able to
reproduce them just now.
By the way is the validation workflow used in BIND written up somewhere
as a separate document, or are the comments in the code the best way to
understand how BIND validates names below a trust anchor (finding either
a valid signature or an insecure delegation).
