Hi Matthew. I'm afraid I don't understand much of what you mean.
(Influence on code? "Reflected file" == the repository data
corresponding to one of the user's files? "What line" of what, when?) If
you are prepared to write a bit more specifically about what you want to
see or understand, we're more likely to be able to point you in the
right direction.
>From your mention of "repository files (0, 1, 2, etc.)" it sounds like
you want to understand Subversions's "fsfs" repository database format.
If so, see this document:
<http://svn.collab.net/repos/svn/trunk/subversion/libsvn_fs_fs/structure>.
However, "fsfs" is just one of two kinds of database in which Subversion
can store its repository; the other is Berkeley DB ("bdb") which is
completely different. Subversion stores its repository "file system"
data (the sequence of revisions of the user's tree of files and
directories, with their properties) in either of these two different
databases, in a higher-level format that is portable between the two.
One way in which you can see this data is when it is serialised or
"dumped" to a "dump file" with the "svnadmin dump" command. It may be
this that you want to see if your interest is in version control rather
than database structure.

If you want to ask questions about how Subversion works, you can ask
here. Note that specific questions are more likely to be answered than
general ones. If you need to ask about how to use Subversion, for
example to use the "svnlook" tool to examine revisions in a repository,
then you should join the "users" list and ask there.
<http://subversion.tigris.org/mailing-lists.html>
Make sure you refer to the book <http://svnbook.red-bean.com/>,
specifically the section entitled "Repository Layer".
