I've attached a minimum org file that shows what I'm trying to do:
essentially to attach a hook to the export process that ends up calling
org-map-entries to make alterations to the file just before it's
exported.
As I've got it now, the hook does change the org buffer, but those
changes are *not* reflected in the exported output. I can only guess
that somehow the export process is able to continue on before the
org-map-entries results are returned? Doesn't seem likely, but...
This is actually kind of the opposite of what I'd like: to have the
changes *only* reflected in the export, and leave the original buffer
unchanged. On the other hand, I can see what thought and care has gone
into setting up a clone buffer for export (and I do need to rely on
buffer-local variables), so maybe an (undo) is my best solution for
returning the buffer to its pre-export state.
But I would like the changes to show up in the exported file!
Thanks in advance,
Eric

The problem is not directly related to the export framework, but to its
relationship with `org-map-entries'.
If you use the following function:
(defun before-export-test (backend)
;; (org-map-entries 'test-map "TODO=\"TODO\"" 'file)
(while (re-search-forward "^\\*+ TODO" nil t)
(test-map)))
it should work.
I don't know why `org-map-entries' behaves badly with export. Meanwhile,
I suggest to not use this function for export hooks.

That'll work! Thanks for looking at this.

I think I fixed the problem wrt `org-map-entries' and export.
You cannot use `file' scope, since it refers to the base buffer
associated to the current buffer file name, which never is the buffer
where the export process takes place.
OTHO, a nil scope (or tree, region for that matter) should be fine with
a very recent Org.

Whoa, not only does it work, it leaves the original buffer unmodified,
as per my wishlist. Many thanks! I don't know when you find the time to
sleep.
