There is a laaarge directory at /var/spool/news/message.id/XYZ (XYZ is a number from 000 to 999). In each of them there are files like:

-rw-rw----    2 news news   1859 Jan 21 18:54 <xn0p12g7h5ry4qw001@reader443.eternal-september.org>
-rw-rw-r--    2 news news   2097 Nov  8  2022 <xnv8npfi32.fsf@delorie.com>
-rw-rw-r--    2 news news   6166 May  3  2020 <yYednTKeUchmMzPDnZ2dnUU78bPNnZ2d@brightview.co.uk>
-rw-rw----    2 news news   1744 May 30  2023 <ykidM.6583948$MJk2.4595004@usenetxs.com>
-rw-rw----    2 news news   1350 Mar 18  2023 <zNhRL.3082038$odm4.1878141@usenetxs.com>
-rw-rw-r--    2 news news   1299 May 16  2020 <zqRvG.281744$yo4.260018@fx48.iad>
-rw-rw-r--    2 news news   1567 Sep  3  2014 <zxr250cc.5qytbc@no-mx.forums.opensuse.org>

Then there are other directories, one per group. For example, "/var/spool/news/alt/comp/software/thunderbird" holds currently 7687 files, like:

-rw-rw---- 2 news news    1506 Jun  4 13:48 7683
-rw-rw---- 2 news news    1342 Jun  4 13:48 7684
-rw-rw---- 2 news news    1065 Jun  4 13:48 7685
-rw-rw---- 2 news news    2003 Jun  4 14:28 7686
-rw------- 1 news news       0 Jun  4 14:28 .last.posting
drwxr-x--- 2 news news  135168 Jun  4 14:28 ./
-rw-r----- 1 news news 2652349 Jun  4 14:28 .overview

which are hard linked each to a file in message.id/. So there is effectively a single copy of the message even if crossposted to several groups.

I don't know how it can find a particular post by msgid considering that there are a thousand subdirectories (000 to 999), but it does.
