   - `projects.update` with `clientId: z.string().nullable().optional()` allows three states: undefined (don't change), null (unlink), string (assign)
   - Auto-expanding all groups during search (`effectiveExpanded` computed from grouped keys) gives a better UX than forcing users to manually expand

+- What was implemented:
+  - Full Global Tasks view UI at `/tasks` route
+  - 4 stat cards (Total Tasks, To Do, In Progress, Completed) using shadcn/ui Card components with Lucide icons, reactively updated from unfiltered `tasks.list` query
+  - Search bar with 300ms debounce using shadcn/ui Input + Search icon
+  - Status filter tabs using shadcn/ui Tabs (All | To Do | In Progress | Completed)
+  - "Order by" dropdown using shadcn/ui DropdownMenu (Due Date | Priority | Created Date)
+  - Task rows with: shadcn/ui Checkbox (toggles todo↔done), title (bold 14px), description (muted truncated), priority Badge (HIGH=destructive, MEDIUM=secondary, LOW=outline green), due date chip (calendar icon + formatted date), breadcrumb (Client > Sub-Client > Project with ChevronRight separators), assignee (User icon + name)
+  - Completed task rows have green-tinted background (`bg-green-50 border-green-200`)
+  - NewTaskDialog component with: Input for title (required), Textarea for description, Select for priority/status, Popover+Calendar for due date, Select for project (from `projects.listAll`), Input for assignee
+  - Installed shadcn/ui components: card, tabs, checkbox, badge, textarea, popover, calendar
+- Files changed: `src/renderer/routes/tasks.tsx`, `src/renderer/components/tasks/NewTaskDialog.tsx` (new), `src/renderer/components/ui/card.tsx` (new), `src/renderer/components/ui/tabs.tsx` (new), `src/renderer/components/ui/checkbox.tsx` (new), `src/renderer/components/ui/badge.tsx` (new), `src/renderer/components/ui/textarea.tsx` (new), `src/renderer/components/ui/popover.tsx` (new), `src/renderer/components/ui/calendar.tsx` (new), `scripts/ralph/prd.json`, `scripts/ralph/progress.txt`
+- **Learnings for future iterations:**
+  - Use two separate `tasks.list` queries: one unfiltered `{}` for stat card counts, one with filters for the displayed list — ensures stats always reflect total counts
+  - `date-fns` `format(date, 'PPP')` produces "February 20th, 2026" style dates — already installed as a dependency of react-day-picker (shadcn/ui calendar)
+  - shadcn/ui Select with an empty string value (`<SelectItem value="">No project</SelectItem>`) works as a "none" option for optional fields
+  - The Popover+Calendar date picker pattern is standard shadcn/ui: Popover wraps a Button trigger showing the formatted date, PopoverContent contains the Calendar
+  - Electron app runs at `http://localhost:5173` in dev mode but only within the Electron BrowserWindow — Playwright browser testing requires the Electron-specific test harness, not direct URL navigation
