Doctor Command
Domain: Installation & Setup
Motivation
The dsh launcher does not ship a dedicated doctor subcommand; install and runtime health are checked with dsh --version and the configuration dump flags instead. --dump-default-config and --dump-config let you inspect the composed tree without booting it. A developer cares because these are the real diagnostics the CLI provides.
Concrete Example
Use dsh --version for the runtime and --dump-config / --dump-default-config to inspect the composed profile without booting it.
Analogy
Like using the built-in gauges and inspection mirror instead of a separate diagnostic app.
