# NOTE: We deliberately do NOT auto-update via VCS on every restart.
# A tampered or force-pushed remote would otherwise execute new code as
# the bot user on every restart.  Update the bot manually:
#     cd /home/neo-bot/neo-bot
#     git fetch --tags
#     git checkout <tag>
#     systemctl restart neo-bot

# Inject the GitHub token via systemd credentials.  The file is mounted
# read-only at $CREDENTIALS_DIRECTORY/github_token (mode 0400, owned by
# the service user) and is not visible to other processes.
