# App Remix Create an independent source repository from an installed App Store app. The prompt must name the installed source app id, the target scoped name, and the target local app id. ## Invariants 1. Treat the source app as read-only. 2. Use `system:app_management` for the copy. Do not download, extract, or copy the bundle with shell commands. 3. Use the target local app id from the prompt. Do not invent another id. It must be the scoped name flattened for local paths (`@ray/calendar` → `ray-calendar`, with underscores changed to hyphens). 4. Keep every file in the published bundle root. Do not assume the app has a `src/` directory. 5. Keep the source version. Change it only when the user's requested work needs a new release version. 6. Isolate runtime artifact names and database storage before installation. The source app remains installed, so the two apps must coexist without shared registry names or tables. 7. Create an independent Git history before applying the user's requested product changes. ## Create the source tree Call `system:app_management` once: ```jsonc { "op": "create", "appId": "<target-local-app-id>", "name": "<target-scoped-name>", "from": { "appId": "<installed-source-app-id>" } } ``` Stop if the action fails. Do not work around an `includeSource` rejection, a bundle integrity error, or a destination conflict. Ask the user to choose a different target name when the target id already exists. Use the returned `rootPath` as `$REP...
