Isn't there an unwritten law prohibiting document viewers changing the

If there is, ebook-viewer, part of calibre, doesn't respect it:
diff -r m/META-INF/calibre_bookmarks.txt m1/META-INF/calibre_bookmarks.txt
1c1
< calibre_current_page_bookmark^7# *:eq(0)> *:eq(1)> *:eq(0)>
*:eq(4)> *:eq(6) |0.19047619047619047

The directories that I compared contain unzipped versions of the same
epub file before and after an invocation of ebook-viewer. Probably
calibre_bookmarks.txt was put in the epub file by ebok-viewer in the
first place.
Now one could say, that this is harmless, because it doesn't change
the way the epub file will appear in any reader. But it changes
filesize and timestamp, enough to make backup software notice.
Hopefully, unchecking the "Remember the current page when quitting" in
the Preferences is a workaround, but even then, it's just a
workaround. ebook-viewer is welcome to have its own little database of
bookmarks, but shouldn't annotate my books.
This would best be reported to Calibre's upstream bug tracker:
https://bugs.launchpad.net/calibre
They're a very responsive upstream, so I imagine you'll get a prompt
answer.
I can see value in having the bookmarks be a separate thing, it allows multiple
readers against a single document, which might be shared in a business
environment, or even read-only. Being able to have a single original document
and let everyone have their own personal current page and bookmarks and possibly
annotation, would be a good thing. Unfortunately that sounds like a fairly major
change to the existing behavior, so it may not be practical.
