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
Tested: bun run check:desktop
Tested: cd desktop && bun run check:electron
Tested: CSC_IDENTITY_AUTO_DISCOVERY=false bun run electron📦dir
Tested: bun run test:package-smoke --platform macos --package-kind dir --artifacts-dir desktop/build-artifacts/electron
Tested: Computer Use read packaged Electron app window at desktop/build-artifacts/electron/mac-arm64/Claude Code Haha.app
Not-tested: Developer ID signed/notarized Gatekeeper launch
Not-tested: Real OS notification click-to-session action
Not-tested: Windows and Linux packaged app smoke on real hosts
The generated logo asset carried both an opaque square canvas and an inner rounded tile, so the desktop empty state and sidebar rendered a visible nested background. Rebuilt the canonical app icon with transparent outside corners, one white rounded badge, and a centered mark, then regenerated the Tauri icon set and docs raster assets from that source.
Constraint: Existing desktop views consume /app-icon.png directly with no wrapper background to remove.
Rejected: Add CSS masking around each img usage | would leave native app icons and docs assets with the same nested canvas problem.
Confidence: high
Scope-risk: narrow
Directive: Keep desktop/src-tauri/app-icon.png as the canonical 1024 RGBA source before regenerating platform icons.
Tested: cd desktop && bun run build; npm run --loglevel=error docs:build; git diff --check; sips alpha and size checks; iconutil icns size ladder; Chrome DevTools light and forced-dark screenshots.
Not-tested: full bun run verify gate, per prior instruction to skip local gate for this logo pass.
The desktop app and documentation need to present the new logo consistently, so the canonical 1024px source icon now feeds the Tauri icon family, desktop public assets, README images, and VitePress brand imagery.
Constraint: Tauri bundle icons are generated assets and must be refreshed from the source icon rather than relying on README or public image replacement alone
Rejected: Rename logo paths | existing README, desktop, and docs references can keep stable paths and pick up the new files directly
Confidence: high
Scope-risk: moderate
Directive: Regenerate desktop/src-tauri/icons whenever desktop/src-tauri/app-icon.png changes
Tested: cd desktop && bun run build; npm run --loglevel=error docs:build; git diff --check; iconutil expanded icon.icns size ladder
Not-tested: full local quality gate per request
Desktop sessions can switch provider and model while a CLI subprocess is already alive, so the server now serializes runtime restarts and marks provider-managed launches to prevent stale settings env from overriding the selected provider. Provider settings also write API key env consistently and clear stale managed keys before syncing.
This includes the related desktop/docs brand asset refresh and keeps the desktop locale default in Chinese, with tests updated to match the current provider semantics.
Constraint: Session-scoped model selection must win over cc-haha/settings.json and inherited ANTHROPIC_* values.
Rejected: Store the selected model as a global provider activeModel | chat runtime selection is per session.
Confidence: high
Scope-risk: moderate
Directive: Do not remove CLAUDE_CODE_PROVIDER_MANAGED_BY_HOST without validating Desktop provider switching against stale settings env.
Tested: bun test src/server/__tests__/conversation-service.test.ts src/server/__tests__/conversations.test.ts src/server/__tests__/providers.test.ts src/server/__tests__/providers-real.test.ts
Tested: cd desktop && bun run test src/stores/settingsStore.test.ts
Tested: cd desktop && bun run lint
Tested: git diff --check
Not-tested: Full desktop production package/signing.
