+# Electron Shell
+
+Electron main-process package for MetoYou / Toju. This directory owns desktop bootstrap, the preload bridge, IPC handlers, desktop persistence glue, updater integration, and window-level behavior.
+
+## Commands
+
+- `npm run build:electron` builds the Electron TypeScript output to `dist/electron`.
+- `npm run electron` builds the product client and Electron, then launches the desktop app.
+- `npm run electron:dev` starts the Angular client and Electron together.
+- `npm run dev` starts the full desktop stack: server, Angular client, and Electron.
+- `npm run electron:build`, `npm run electron:build:win`, `npm run electron:build:mac`, and `npm run electron:build:linux` create packaged desktop builds.
+
+## Structure
+
+| Path | Description |
+| --- | --- |
+| `main.ts` | Electron app bootstrap and process entry point |
+| `preload.ts` | Typed renderer-facing preload bridge |
+| `app/` | App lifecycle and startup composition |
+| `ipc/` | Renderer-invoked IPC handlers |
+| `cqrs/` | Local database command/query handlers and mappings |
+| `db/`, `entities/`, `migrations/` | Desktop persistence and schema evolution |
+| `audio/` | Desktop audio integrations |
+| `update/` | Desktop updater flow |
+| `window/` | Window creation and window-level behavior |
+
+## Notes
+
+- When adding a renderer-facing capability, update the Electron implementation, `preload.ts`, and the renderer bridge in `toju-app/` together.
+- Treat `dist/electron/` and `dist-electron/` as generated output.
+- See [AGENTS.md](AGENTS.md) for package-level editing rules.
