help with corrupted files; ticked articles missing

[akb+lists.ding@mirror.to (Andrew B)]

The partition containing my home directory filled up, and I cleared
space and exited gnus, though I am not sure in what order. 

At present, when I start gnus, the group that I was reading
when the disk filled up has a Group buffer line like this:
3:       2 /    1! 124410: nnimap+machinename:INBOX

but it should look more like this:
3:      80 /  997! 124410: nnimap+machinename:INBOX

When I enter the group, no matter how many articles I tell gnus to
fetch, it only shows those two unread articles. The read articles
are still on the server, gnus just won't fetch and display them.

Other groups behave normally; I can hit C-u RET and it will fetch
as many articles as I ask for. 

I have a backup from a few days ago that includes
-rw-r--r--  1 username username    250036 Jun 25 18:53 #.newsrc-dribble#
-rw-r--r--  1 username username    241532 May 19 14:45 #.newsrc-dribble#~
-rw-r--r--  1 username username    216738 Jan  5 04:08 .newsrc-dribble
-rw-r--r--  1 username username    201734 Jul  6  2022 .newsrc-dribble~
-rw-r--r--  1 username username    393157 Feb  8  2022 .newsrc.eld
-rw-r--r--  1 username username    392927 Feb  7  2022 .newsrc.eld~
-rw-r--r--  1 username username         0 Dec  6  2019 .newsrc

What can I do to recover my unread and ticked articles?
Are there any files besides .newsrc ones that I need to recover gnus state? 
I'm fine with having to re-read a few days of mail to get the state back
to what it was before the disk filled up.

Thanks very much for any assistance!

I will probably be offline for the next 3-4 days but will respond
to any questions as soon as I return.
