If it's just a reminder to yourself, then I would simply
remove the keybinding for ^D (or bind it to something else;
the details depend on your login shell) and alias "exit"
and "logout" to a script that checks the working directory
of your version control system.  If things have been checked
in correctly, it logs you out, otherwise it prints a message
and terminates, throwing you back to the shell prompt.

Additionally, you could put the checked-out files on a
geli-encrypted device and/or on a memory file system.  That
will make sure that there ist no unencrypted stuff left
behind after a power-failure or crash.
