+This repo now uses `@git.zone/tsswift` with project config in the repo-root `.smartconfig.json`.
 
 - `build` targets macOS, iPhone Simulator, and iPad Simulator in parallel
 - `test` targets macOS, which matches the current test bundle setup
 - `run` defaults to macOS unless you pass `--platform ios` or `--platform ipad`
+- `watch` rebuilds and relaunches macOS, iPhone, and iPad app instances on file changes
 - `launch` starts the app with the configured control-file transport enabled
 - `review` replaces the old shell-script review loop and captures screenshot sets for iPhone, iPad, and macOS
