Summary

• use the real pointer position for sidebar task split-pane drops and suppress sidebar sorting outside its horizontal bounds
• disable both dnd-kit scrolling paths for task drags that can leave the sidebar
• lock the Wework sidebar scroll container while an external pane drag is outside the sidebar, preventing WebKit native edge scrolling
• document the split-drag behavior in Chinese and English

Verification

• reproduced and verified in the Wework desktop app
• pnpm --filter wework exec tsc --noEmit
• focused ESLint on changed Wework files
• pnpm --filter wework test src/components/layout/SidebarSortableList.test.tsx src/components/layout/DesktopSidebar.test.tsx src/components/layout/workbenchPaneStack.test.tsx (111 tests)
• pre-push Wework ESLint, TypeScript, and unit tests

Summary by CodeRabbit

• New Features

  • Added drag-and-drop task splitting from the sidebar into the workbench’s top, bottom, left, or right areas.
  • Dragging a task to the center replaces the current workbench area.

• Bug Fixes

  • Sidebar sorting, scrolling, and auto-scroll now pause during workbench dragging and resume reliably afterward.
  • Improved desktop process cleanup detection to prevent stale sessions after processes exit.

• Documentation

  • Added English and Chinese guidance for splitting tasks by dragging.

📝 Walkthrough

Walkthrough

The change updates workbench task dragging to control sidebar sorting and scrolling. It adds Linux process-group inspection that distinguishes live processes from zombie-only members. Documentation and regression tests cover both behaviors.

Changes

Workbench task dragging

Layer / File(s)	Summary
Sidebar sortable external-drag handling wework/src/components/layout/SidebarSortableList.tsx, wework/src/components/layout/sidebarSortableAutoScroll.ts	Sidebar dragging tracks pointer boundaries, suppresses sorting and auto-scroll outside the sidebar, and dispatches external drag events with live coordinates.
Desktop sidebar drag lifecycle wework/src/components/layout/DesktopSidebar.tsx, wework/src/components/layout/useSidebarPaneDragScrollLock.ts	DesktopSidebar locks the scroll position during external pane drags and restores normal scrolling when the drag ends or is canceled.
Drag validation and documentation wework/src/components/layout/*.test.tsx, docs/en/wework/workbench.md, docs/zh/wework/workbench.md	Tests cover drag state, scrolling, pointer coordinates, and cancellation. Documentation describes directional splitting, center replacement, and sidebar behavior.

Linux process lifecycle

Layer / File(s)	Summary
Linux process-group inspection wework/e2e/desktop/process-lifecycle.mjs	Linux process-group checks parse /proc/<pid>/stat, ignore dead process states, and retain signal-based behavior on non-Linux platforms.
Process lifecycle validation wework/src/e2e/desktop-process-lifecycle.test.ts	Tests cover zombie-only groups, groups with live members, and groups with no matching process statistics.

3702-3739: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Extract the sidebar drag lifecycle into a dedicated hook.

This effect adds an independent global-event and scroll-lock lifecycle to DesktopSidebar, which already extends past Line 4,700. Move this lifecycle into a focused hook that returns the scroll-container ref, outside state, and scroll handler.

As per coding guidelines, split files over 1000 lines and keep functions focused.

locking, and related refs. Have the hook return the worklists scroll-container
ref, outside-sidebar state, and scroll handler, then update DesktopSidebar to
use those outputs while preserving existing behavior and cleanup.
