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: Computer Use read packaged Electron app window at desktop/build-artifacts/electron/mac-arm64/Claude Code Haha.app

Not-tested: Windows and Linux packaged app smoke on real hosts
Desktop destructive confirmations had split implementations: shared ConfirmDialog, hand-rolled modals, inline task popovers, and a diagnostics window.confirm path. This adds shared ActionDialog and ConfirmPopover primitives, keeps ConfirmDialog as the simple two-action wrapper, and migrates the known desktop confirmation flows onto those shared surfaces.
Constraint: Running-tab close needs three actions, so the two-button ConfirmDialog API was not enough.
Rejected: Force every confirmation through ConfirmDialog | would either lose the keep-running action or make ConfirmDialog too broad for inline popovers.
Confidence: high
Scope-risk: moderate
Directive: Add new desktop confirmation flows through ActionDialog, ConfirmDialog, or ConfirmPopover instead of hand-rolled overlays.
Tested: cd desktop && bun run test -- AdapterSettings.test.tsx mcpSettings.test.tsx TabBar.test.tsx PermissionModeSelector.test.tsx diagnosticsSettings.test.tsx
Tested: bun run check:desktop
Tested: git diff --check
Tested: Chrome DevTools smoke for provider delete and diagnostics clear-log confirmation dialogs
Not-tested: Agent Browser smoke because the local agent-browser CLI hung on open/snapshot/doctor/close commands.
Permission mode is a per-session runtime choice, while scheduled tasks cannot rely on a human approval loop. This removes the General settings permission surface, persists session permission metadata, and forces scheduled tasks to run with bypass permissions. Runtime permission changes now handle both directions across bypass boundaries, including startup/prewarm races, by persisting first and restarting only when the CLI launch mode must change.
Constraint: Scheduled tasks must be able to execute without a human standing by for authorization.
Constraint: The CLI only honors bypass permissions when launched with the skip-permissions flag, so switching to or from bypass requires a restart.
Rejected: Keep a global General permission default | it can leak across sessions and scheduled runs in ways the user cannot reason about.
Confidence: high
Scope-risk: broad
Directive: Do not reintroduce a global UI permission selector without proving it cannot affect unrelated sessions or automations.
Tested: bun test src/server/__tests__/conversations.test.ts -t "permission" --timeout 30000 (10 pass, 0 fail)
Tested: bun run check:server (858 pass, 0 fail)
Tested: cd desktop && bun run check:desktop (760 tests plus production build passed)
Tested: desktop/scripts/build-macos-arm64.sh and codesign verification passed
Tested: Real DeepSeek smoke validated plan, bypass, and scheduled task permission behavior
Not-tested: Did not repeat the full DeepSeek smoke after the final startup-race hardening; mock WebSocket permission regression and full server gate were rerun after that change.
Fixes#632
The bypass-permission confirmation was resolving its displayed workspace from the session list's activeSessionId, while the chat composer sends runtime updates to the currently active tab. When those two UI states diverged after tab restores or project switches, the confirmation could show a parent or stale workspace path even though the chat was operating in another project.
Constraint: Desktop tabs and session-list selection can diverge during restore and multi-tab workflows.
Rejected: Thread workDir through every chat-composer call site | the selector already has the active tab context needed for uncontrolled usage.
Confidence: high
Scope-risk: narrow
Directive: Keep uncontrolled permission-mode actions keyed to the same active tab used for set_permission_mode.
Tested: cd desktop && bun run test -- src/components/controls/PermissionModeSelector.test.tsx --run
Tested: cd desktop && bun run lint
Not-tested: Live Windows desktop packaging smoke.
H5 browser use needs to keep local desktop WebUI testing open while giving remote phones a usable chat-first surface. This change scopes browser auth by origin and target host, hides non-chat desktop chrome on H5 mobile, compacts the empty-session composer, and unifies mobile selectors behind a full-width bottom sheet with an explicit close action.
Constraint: Local browser development may bypass H5 auth only for loopback or private LAN server hosts; public or remote hosts still require an H5 token.
Constraint: Mobile H5 scope is chat-first; settings and scheduled-task surfaces stay hidden instead of fully redesigned.
Rejected: Reuse desktop popovers on mobile | hover/anchored dropdown behavior leaves key actions hard to dismiss and cramped on narrow screens.
Rejected: Let any localhost origin bypass remote auth | it would let arbitrary local pages access public H5 servers without a token.
Confidence: medium
Scope-risk: moderate
Directive: Keep future H5 selector popups on MobileBottomSheet unless a selector needs a reviewed custom mobile interaction.
Tested: cd desktop && bun run lint
Tested: cd desktop && bun run test -- src/pages/EmptySession.test.tsx src/components/chat/ChatInput.test.tsx src/lib/desktopRuntime.test.ts src/components/shared/RepositoryLaunchControls.test.tsx src/components/controls/PermissionModeSelector.test.tsx src/components/controls/ModelSelector.test.tsx src/components/shared/DirectoryPicker.test.tsx src/__tests__/pages.test.tsx

Tested: Chrome mobile viewport smoke for context, model, permission, project, branch, and worktree bottom sheets with no horizontal overflow.
Not-tested: Full bun run verify quality gate.
The browser H5 surface now switches to a phone-oriented shell: the sidebar becomes a closed-by-default drawer, chat stays primary, workspace and terminal panels stay off the mobile chat surface, composer controls use larger touch targets, and mobile menus avoid desktop-only widths and keyboard hints. Desktop and Tauri sidebar behavior remain on the existing store-driven path.
Constraint: H5 is personal/team browser access layered on the existing desktop web UI, so the normal desktop app must keep its current layout behavior.
Rejected: Share the global sidebarOpen default for mobile first paint | it can flash the drawer open before effects run on a phone.
Confidence: high
Scope-risk: moderate
Directive: Keep mobile-only layout branching behind useMobileViewport() && !isTauriRuntime() unless a future task explicitly redesigns the native desktop shell.
Tested: cd desktop && bunx vitest run src/hooks/useMobileViewport.test.tsx src/components/layout/AppShell.test.tsx src/components/layout/Sidebar.test.tsx src/pages/ActiveSession.test.tsx src/components/chat/ChatInput.test.tsx src/components/controls/PermissionModeSelector.test.tsx
