The `dsh` command is the product launcher for raw Cordis configurations, the Web UI, and one-shot headless tasks. [`src/args.ts`](src/args.ts) owns the command grammar, and [`src/bin.ts`](src/bin.ts) loads only the selected runner. Invalid commands, options from another mode, configuration errors, and boot failures exit nonzero.
The invoking directory is the default workspace root. Web and headless share the shipped provider, persistence, policy, tool, repository Plugin, and telemetry composition; raw config selects its own deployment-specific front door.
Raw `dsh` requires `--config`. The named patch list is applied directly over [`config/base.cordis.yml`](config/base.cordis.yml); it is not a complete replacement tree and does not add a surface overlay or personal `$DSH_HOME/config.yaml`. Use `--dump-default-config` and `--dump-config` to inspect the resulting tree without booting it.
Production Web and headless runs require built package and frontend artifacts. From a checkout, `pnpm run dsh` runs the TypeScript entry and forwards arguments; the [source-launcher reference](reference/README.md#source-launcher) describes the PATH symlink and module-resolution contract.
