What? I did not commend out the record_route section:

The reason I commented out the loose_route() section was specifically to
illustrate that dialog correlation does not occur _without_ it. I
normally have it enabled.
That was the topic of my original post: how to correlate dialogs purely
based on SIP attributes without the use of loose-routing.
It would seem to follow from what you are saying, from the documentation
hint you reference (which I read before), and from my examination of the
source code to see how the dialog correlation works that the only way it
could possibly work is through the use of a dialog correlate attribute
in the Route: header. That is why a call to loose_route() is necessary,
and that is why subsequent in-dialog requests do not get correlated
without it.

Your config is bogus. You are not
doing proper record-routing (you
commented out that section).
In-dialog requests are matched during record-route handling,
regardless of the dialog match mode.
The documentation is a little bit fuzzy about this, but here's the hint:

This PV will be available only for sequential requests, after doing
loose_route().

So it means that you must perform loose_route() if you want to catch
in-dialog request and have a consistent dialog state. With your
config, all the dialogs will just time out ... Post your
config and the trace of a bad call (ngrep + kamailio logs).
