Add per-session zoom state, route the zoom factor through the desktop preview bridge, and apply it to the Electron WebContentsView before preview capture so screenshot and annotation coordinates stay on the native preview surface.
Tested:
- cd desktop && bun run test -- src/components/browser/BrowserSurface.test.tsx src/stores/browserPanelStore.test.ts src/components/workbench/WorkbenchPanel.webview.test.tsx src/lib/previewBridge.test.ts src/lib/desktopHost/electronHost.test.ts
- cd desktop && bun test electron/services/preview.test.ts
- cd desktop && bun run lint
- cd desktop && bun run build
- cd desktop && bun run check:electron
Not-tested:
- cd desktop && bun run check:desktop (blocked by existing MessageList relative-time assertion and TabBar AbortSignal errors)
Confidence: medium
Scope-risk: moderate
Use Electron WebContentsView capturePage for browser preview screenshots and selection annotations so captured images match the rendered preview.
Tested:
- cd desktop && bun run test -- electron/services/preview.test.ts src/lib/previewEvents.test.ts src/components/browser/BrowserSurface.test.tsx src/preview-agent/screenshot.test.ts src/preview-agent/picker.test.ts src/preview-agent/editBubble.test.ts
- cd desktop && bun run lint
- cd desktop && bun run build
- bun run check:desktop
- bun run check:electron
- bun run check:native
Not-tested:
- Real GUI click-through for Screenshot / Select Element; Electron runtime launch was blocked in this shell and packaged build did not enter the smoke path.
Constraint: GUI click-through smoke was blocked by local Electron launch behavior; package smoke passed but does not launch the app.
Confidence: medium
Scope-risk: narrow
Introduce the Electron desktop shell alongside the existing React renderer and local Bun server boundary. The migration keeps the DesktopHost contract explicit across Tauri, Electron, and browser runtimes while adding Electron main/preload services for dialogs, shell, notifications, updates, tray/window lifecycle, terminal, preview WebContentsView, app mode, and release/package validation.
The commit also carries the latest local main desktop command updates, including agent slash entries and hidden-by-default markdown thinking details, so the packaged Electron build matches the current main UX surface.
Constraint: React renderer, local Bun server, REST/WebSocket, and sidecar boundaries must remain reusable during the migration
Constraint: macOS dev packages are ad-hoc signed and cannot prove Developer ID notarization or Gatekeeper release launch
Rejected: Browser-only smoke validation | it cannot exercise native dialogs, keychain prompts, notification behavior, or packaged app startup
Confidence: medium
Scope-risk: broad
Directive: Do not remove Tauri host support until signed Electron release artifacts pass native OS smoke on macOS, Windows, and Linux
