The key that the website logs in with was written into the authorized_keys
of the Administrator, which would have given everyone who has the website
administrator rights on the box. It only gets access as the root user.
The deploy script logs in as Administrator with the personal key of the
deployer instead, from the agent or from -i.

The key that the website logs in with lives in the home directory of the
user, so a deleted home directory took it away and the site could not
connect any more. The key is now one of the copies the cleanup restores,
and it is merged into the authorized_keys of the user, so that keys they
added stay.
The installer writes the same key for the Administrator, and the deploy
script checks that it is the key the website uses.

It logs in as Administrator, whose shell is a Windows one, copies the
scripts and the resources to the server and runs the installer there. It
uses the key the website uses and checks the host key against the one
the website pins.

The shell configuration was copied from the server by hand. It now has
its own directory, which make_files.py copies into the resources, so
that the resources are the whole set of files the cleanup restores and
nothing has to be copied by hand.

The cleanup job now restores the whole home directory instead of only
the four text files: the directory itself, the shell configuration that
gives the prompt, and the files. Anything that is not a regular file is
replaced, so the files stay text files.
The README in server/ describes the security model: the box is a
disposable VPS that may be compromised, the root user may do whatever
they want, and only the prompt, the home directory and the four files
are kept working.

The README and Code of Conduct files move to server/resources, the
scripts that build and deploy them to server/scripts. The new
install_restore_task.ps1 installs a scheduled task as SYSTEM that puts
the files back every 30 minutes, so the shell server's root user can
neither stop it nor change the copies it restores from.
