$node is a YAML::Node and the EXISTS function only checks for

though "$node->{version}" is true.
Gar.
How I missed that I have no idea. Clearly I was working on it and
thought I solved it but didn't, as even M::B's own META.yml is
screwed up.
You should see M::B 0.2802's META.yml though - even worse! =)
This does explain the totally bizarre behavior I was seeing which
made me put the ... if exists() business in there to begin with.
Gee, I love YAML. (Sigh.)
You and me both.
Dropping the "exists" or changing that to "ref $node->{version}"
makes it all work just fine.
Not ideal either, but certainly better. I guess it would only fail
if someone intends to have a version 0 or '' or whatever. Maybe I'll
just concatenate with the empty string, though.
