Errm.. I think its because you imported that in ? Please check revision 2 of your repository. You’ll see a commit from yourself where I think you’ve checked in a full bare SVN repository, rather than creating a dump file and doing an import from our web interface:

http://docs.xp-dev.com/user-guide/sourcecontrol.html

Instructions on importing Subversion repositories are somewhere in the middle of that page.

I think you need to follow our tutorial:

http://docs.xp-dev.com/tutorials/subversion.html

... the same set of files and folders end up in each branch, hence no apparent way out ...

Which same files and folders ? hooks, db, conf, locks ?

I’ve just checked your repositories, and none of them have the hooks, db, conf, locks folders. (Use the “Explore Repository” link on your Source Control panel)
