Two-pane tmux session with file-based message passing: - tower-hermes.sh: Hermes side (cloud/Claude) - tower-timmy.sh: Timmy side (HERMES_HOME=~/.timmy) - tower-watchdog.sh: self-healing, restarts dead panes - tower-session.sh: tmux bootstrap script Communication via ~/.tower/*.msg files. Both agents maintain named sessions (tower-hermes, tower-timmy) for conversation continuity across restarts.
