Driving tty7 from the command line

tty7 is a thin, non-interactive client of the tty7 server. Every verb returns and exits; --json makes the output machine-readable. The GUI never has to be running — the server is what owns the panes.

First: where are you?

tty7 doctor

One table, and it answers everything you need before doing anything else: whether a server is reachable, whether the dialect matches, whether each agent's status hooks are installed, and whether TTY7_CONFIG_DIR / TTY7_WS / TTY7_PANE are set — i.e. whether you are running inside a tty7 pane.
