As far as I understand it, these are not permanent files that are stored
anywhere: they're generated by the cgit interface on-demand. If the
precise details of how it generates that snapshot change, so will the
resulting tarball.

The files contained in the tarball are part of the git history (the
thing that the repository browser reports has not changed in 3 years),
but the headers/metadata in the tarball, and the gzip compression layer
around it, are not necessarily guaranteed to remain the same.

If you want something verifiable that shouldn't change, either use the
official tarball release from here:

or use the git command-line tool to check out a particular tag.
