+
+TypeScript client library for ResolveSpec APIs. Supports body-based REST, header-based REST, and WebSocket protocols. Aligns with Go backend types.
+
+## Clients
+
+| Client | Protocol | Singleton Factory |
+|---|---|---|
+| `ResolveSpecClient` | REST (body JSON) | `getResolveSpecClient(config)` |
+| `HeaderSpecClient` | REST (HTTP headers) | `getHeaderSpecClient(config)` |
+| `WebSocketClient` | WebSocket | `getWebSocketClient(config)` |
+
+Singleton factories cache instances keyed by URL.
+
+## Config
+
+```typescript
+interface ClientConfig {
+  baseUrl: string;
+  token?: string;  // Bearer token
+}
+
+interface WebSocketClientConfig {
+  url: string;
+  reconnect?: boolean;
+  reconnectInterval?: number;
+  maxReconnectAttempts?: number;
+  heartbeatInterval?: number;
+  debug?: boolean;
+}
+```
+
+## ResolveSpecClient (Body-Based REST)
+
+```typescript
+import { ResolveSpecClient, getResolveSpecClient } from '@warkypublic/resolvespec-js';
+
+const client = new ResolveSpecClient({ baseUrl: 'http://localhost:3000', token: 'your-token' });

+# @warkypublic/zustandsyncstore v1.0.0
+
+React library providing synchronized Zustand stores with prop-based state management and persistence support.
+
+## Peer Dependencies
+
+- `react` >= 19.0.0
+- `zustand` >= 5.0.0
+- `use-sync-external-store` >= 1.4.0
+
+## Runtime Dependencies
+
+- `@warkypublic/artemis-kit`
+
+## API
+
+Single export: `createSyncStore`
+
+```typescript
+import { createSyncStore } from '@warkypublic/zustandsyncstore';
+```
+
+### createSyncStore<TState, TProps>(createState?, useValue?)
+
+**Parameters:**
+- `createState` (optional): Zustand `StateCreator<TState>` function
+- `useValue` (optional): Custom hook receiving `{ useStore, useStoreApi } & TProps`, returns additional state to merge
+
+**Returns:** `SyncStoreReturn<TState, TProps>` containing:
+- `Provider` — React context provider component
+- `useStore` — Hook to access the store
+
+### Provider Props
+
+| Prop | Type | Description |
+|---|---|---|
+| `children` | `ReactNode` | Required |
+| `firstSyncProps` | `string[]` | Props to sync only on first render |
+| `persist` | `PersistOptions<Partial<TProps & TState>>` | Zustand persist config |
+| `waitForSync` | `boolean` | Wait for sync before rendering children |
+| `fallback` | `ReactNode` | Shown while waiting for sync |
+| `...TProps` | `TProps` | Custom props synced to store state |
+
+### useStore Hook
+
+```typescript
+const state = useStore();                                    // entire state (TState & TProps)
+const count = useStore(state => state.count);                // with selector
+const count = useStore(state => state.count, (a, b) => a === b);  // with equality fn
+```
+
+## Usage
+
+### Basic
+
+```tsx
+interface MyState { count: number; increment: () => void; }
+interface MyProps { initialCount: number; }
+
+const { Provider, useStore } = createSyncStore<MyState, MyProps>(
+  (set) => ({
+    count: 0,
+    increment: () => set((state) => ({ count: state.count + 1 })),
+  })
+);
+
+function Counter() {
+  const { count, increment } = useStore();
+  return <button onClick={increment}>Count: {count}</button>;
+}
+
+function App() {
+  return (
+    <Provider initialCount={10}>
+      <Counter />
+    </Provider>
+  );
+}
+```
+
+### With Custom Hook Logic
+
+```tsx
+const { Provider, useStore } = createSyncStore<MyState, MyProps>(
+  (set) => ({ count: 0, increment: () => set((s) => ({ count: s.count + 1 })) }),
+  ({ useStore, useStoreApi, initialCount }) => {
+    const currentCount = useStore(state => state.count);
+    return { computedValue: initialCount * 2 };
+  }
+);
+```
+
+### With Persistence
+
+```tsx
+<Provider initialCount={10} persist={{ name: 'my-store', storage: localStorage }}>
+  <Counter />
+</Provider>
+```
+
+### Selective Prop Syncing
+
+```tsx
+<Provider initialCount={10} otherProp="value" firstSyncProps={['initialCount']}>
+  <Counter />
+</Provider>
+```
+
+## Internal Types
+
+```typescript
+type LocalUseStore<TState, TProps> = TState & TProps;
+
+// Store state includes a $sync method for internal prop syncing
+type InternalStoreState<TState, TProps> = TState & TProps & {
+  $sync: (props: TProps) => void;
+};
+
+type SyncStoreReturn<TState, TProps> = {
+  Provider: (props: { children: ReactNode } & {
+    firstSyncProps?: string[];
+    persist?: PersistOptions<Partial<TProps & TState>>;
+    waitForSync?: boolean;
+    fallback?: ReactNode;
+  } & TProps) => React.ReactNode;
+  useStore: {
+    (): LocalUseStore<TState, TProps>;
+    <U>(selector: (state: LocalUseStore<TState, TProps>) => U, equalityFn?: (a: U, b: U) => boolean): U;
+  };
+};
+```

+# ErrorManager
+
+Centralized error reporting for ErrorBoundary components.
+
+## Setup
+
+### Sentry Integration
+
+```typescript
+import { errorManager } from './ErrorBoundary';
+
+errorManager.configure({
+  enabled: true,
+  sentry: {
+    dsn: 'https://your-sentry-dsn@sentry.io/project-id',
+    environment: 'production',
+    release: '1.0.0',
+    sampleRate: 1.0,
+    ignoreErrors: ['ResizeObserver loop limit exceeded'],
+  },
+});
+```
+
+### Custom API Integration
+
+```typescript
+errorManager.configure({
+  enabled: true,
+  customAPI: {
+    endpoint: 'https://api.yourapp.com/errors',
+    method: 'POST',
+    headers: {
+      'Authorization': 'Bearer token',
+    },
+    transformPayload: (report) => ({
+      message: report.error.message,
+      stack: report.error.stack,
+      level: report.severity,
+      timestamp: report.timestamp,
+    }),
+  },
+});
+```
+
+### Custom Reporter
+
+```typescript
+errorManager.configure({
+  enabled: true,
+  reporters: [
+    {
+      name: 'CustomLogger',
+      isEnabled: () => true,
+      captureError: async (report) => {
+        console.error('Error:', report.error);
+      },
+    },
+  ],
+});
+```
+
+### Multiple Reporters
+
+```typescript
+errorManager.configure({
+  enabled: true,
+  sentry: { dsn: 'your-dsn' },
+  customAPI: { endpoint: 'your-endpoint' },
+  reporters: [customReporter],
+});
+```
+
+## Hooks
+
+### beforeReport
+
+```typescript
+errorManager.configure({
+  beforeReport: (report) => {
+    // Filter errors
+    if (report.error.message.includes('ResizeObserver')) {
+      return null; // Skip reporting
+    }
+
+    // Enrich with user data
+    report.context = {
+      ...report.context,
+      user: { id: getCurrentUserId() },
+      tags: { feature: 'checkout' },
+    };
+
+    return report;
+  },
+});
+```
+
+### onReportSuccess / onReportFailure
+
+```typescript
+errorManager.configure({
+  onReportSuccess: (report) => {
+    console.log('Error reported successfully');
+  },
+  onReportFailure: (error, report) => {
+    console.error('Failed to report error:', error);
+  },
+});
+```
+
+## Manual Reporting
+
+```typescript
+try {
+  riskyOperation();
+} catch (error) {
+  await errorManager.reportError(error as Error, null, {
+    namespace: 'checkout',
+    tags: { step: 'payment' },
+    extra: { orderId: '123' },
+  });
+}
+```
+
+## Disable/Enable
+
+```typescript
+// Disable reporting
+errorManager.configure({ enabled: false });
+
+// Enable reporting
+errorManager.configure({ enabled: true });
+```
+
+## ErrorBoundary Integration
+
+Automatic - errors caught by `ReactErrorBoundary` or `ReactBasicErrorBoundary` are automatically reported.
+
+Manual report button in `ReactErrorBoundary` UI also sends to ErrorManager.
+
+## Install Sentry (optional)
+
+```bash
+npm install @sentry/react
+```
+
+## Types
+
+```typescript
+type ErrorSeverity = 'fatal' | 'error' | 'warning' | 'info' | 'debug';
+
+interface ErrorContext {
+  namespace?: string;
+  componentStack?: string;
+  user?: Record<string, any>;
+  tags?: Record<string, string>;
+  extra?: Record<string, any>;
+}
+
+interface ErrorReport {
+  error: Error;
+  errorInfo?: any;

+# GlobalStateStore
+
+Zustand-based global state management with automatic persistence.
+
+## Quick Start
+
+```tsx
+import {
+  GlobalStateStoreProvider,
+  useGlobalStateStore,
+  useGlobalStateStoreContext
+} from './GlobalStateStore';
+
+// Wrap app with provider
+function App() {
+  return (
+    <GlobalStateStoreProvider
+      apiURL="https://api.example.com"
+      fetchOnMount={true}
+      throttleMs={5000}
+    >
+      <MyComponent />
+    </GlobalStateStoreProvider>
+  );
+}
+
+// Use in components
+function MyComponent() {
+  const { program, session, user } = useGlobalStateStore();
+  const { refetch } = useGlobalStateStoreContext();
+
+  return (
+    <div>
+      {program.name}
+      <button onClick={refetch}>Refresh</button>
+    </div>
+  );
+}
+
+// Outside React
+const apiURL = GlobalStateStore.getState().session.apiURL;
+GlobalStateStore.getState().setAuthToken('token');
+```
+
+## Provider Props
+
+- **apiURL** - Initial API URL (optional)
+- **autoFetch** - Enable automatic fetching (default: `true`)
+- **fetchOnMount** - Fetch data when provider mounts (default: `true`)
+- **throttleMs** - Minimum time between fetch calls in milliseconds (default: `0`)
+
+## Context Hook
+
+`useGlobalStateStoreContext()` returns:
+- **fetchData(url?)** - Throttled fetch function
+- **refetch()** - Refetch with current URL
+
+## State Slices
+
+- **program** - name, logo, description, tags, version
+- **session** - apiURL, authToken, connected, loading, error, parameters, meta
+- **owner** - id, name, logo, settings, theme (darkMode, name)
+- **user** - username, email, fullNames, isAdmin, avatarUrl, parameters, theme (darkMode, name)
+- **layout** - leftBar, rightBar, topBar, bottomBar (each: open, collapsed, pinned, size, menuItems)
+- **navigation** - menu, currentPage
+- **app** - environment, updatedAt, controls, globals
+
+## Actions
+
+**Program:** `setProgram(updates)`
+**Session:** `setSession(updates)`, `setAuthToken(token)`, `setApiURL(url)`
+**Owner:** `setOwner(updates)`
+**User:** `setUser(updates)`
+**Layout:** `setLayout(updates)`, `setLeftBar(updates)`, `setRightBar(updates)`, `setTopBar(updates)`, `setBottomBar(updates)`
+**Navigation:** `setNavigation(updates)`, `setMenu(items)`, `setCurrentPage(page)`
+**App:** `setApp(updates)`
+**Complex:** `fetchData(url?)`, `login(token?)`, `logout()`
+
+## Custom Fetch
+
+```ts
+GlobalStateStore.getState().onFetchSession = async (state) => {
+  const response = await fetch(`${state.session.apiURL}/session`, {
+    headers: { Authorization: `Bearer ${state.session.authToken}` }
+  });
+  const data = await response.json();
+
+  return {
+    program: { name: data.appName, ... },
+    user: { id: data.userId, name: data.userName, ... },
+    navigation: { menu: data.menu },
+  };
+};
+```
+
+## Persistence
+
+Auto-saves to IndexedDB (localStorage fallback).
+Auto-loads on initialization.
+Skips transient data: loading states, errors, controls.
+
+## TypeScript
+
+Fully typed with exported types:
+`GlobalState`, `ProgramState`, `SessionState`, `OwnerState`, `UserState`, `ThemeSettings`, `LayoutState`, `BarState`, `NavigationState`, `AppState`

+# Griddy - Implementation Context
+
+## What Is This
+Griddy is a data grid component in the Oranguru package (`@warkypublic/oranguru`), built on TanStack Table + TanStack Virtual with Zustand state management.
+
+## Architecture
+
+### Two TanStack Libraries
+- **@tanstack/react-table** (headless table model): sorting, filtering, pagination, row selection, column visibility, grouping
+- **@tanstack/react-virtual** (virtualization): renders only visible rows from the table's row model
+
+### State Management
+- **createSyncStore** from `@warkypublic/zustandsyncstore`
+- `GriddyProvider` wraps children; props auto-sync into the store via `$sync`
+- `useGriddyStore((s) => s.fieldName)` to read any prop or UI state
+- `GriddyStoreState` must explicitly declare all prop fields from `GriddyProps` for TypeScript visibility
+- UI state (focus, edit mode, search overlay, selection mode) lives in the store
+- TanStack Table/Virtual instances stored as `_table`, `_virtualizer` in the store
+
+### Component Tree
+```
+<Griddy props>                        // forwardRef wrapper
+  <GriddyProvider {...props}>         // createSyncStore Provider, syncs all props
+    <GriddyErrorBoundary>             // class-based error boundary with retry
+      <GriddyInner>                   // sets up useReactTable + useVirtualizer
+        <SearchOverlay />             // Ctrl+F search (with search history)
+        <AdvancedSearchPanel />       // multi-condition boolean search
+        <GridToolbar />               // export, column visibility, filter presets
+        <div tabIndex={0}>            // scroll container, keyboard target
+          <TableHeader />             // headers, sort indicators, filter popovers
+          <GriddyLoadingSkeleton />   // shown when isLoading && no data
+          <VirtualBody />             // maps virtualizer items -> TableRow
+            <TableRow />             // focus/selection CSS, click handler
+              <TableCell />          // flexRender, editors, custom renderers
+          <GriddyLoadingOverlay />   // translucent overlay when loading with data
+        </div>
+        <PaginationControl />         // page nav, page size selector
+      </GriddyInner>
+    </GriddyErrorBoundary>
+  </GriddyProvider>

+
+## Key Props (GriddyProps<T>)
+| Prop | Type | Purpose |
+|------|------|---------|
+| `data` | `T[]` | Data array |
+| `columns` | `GriddyColumn<T>[]` | Column definitions |
+| `selection` | `SelectionConfig` | none/single/multi row selection |
+| `search` | `SearchConfig` | Ctrl+F search overlay |
+| `advancedSearch` | `{ enabled }` | Multi-condition search panel |
+| `pagination` | `PaginationConfig` | Client/server-side pagination |
+| `grouping` | `GroupingConfig` | Data grouping |
+| `isLoading` | `boolean` | Show skeleton/overlay |
+| `showToolbar` | `boolean` | Export + column visibility toolbar |
+| `filterPresets` | `boolean` | Save/load filter presets |
+| `onError` | `(error) => void` | Error boundary callback |
+| `onRetry` | `() => void` | Error boundary retry callback |
+| `onEditCommit` | `(rowId, colId, value) => void` | Edit callback |
+| `manualSorting/manualFiltering` | `boolean` | Server-side mode |
+| `persistenceKey` | `string` | localStorage key for presets/history |
+
+## GriddyColumn<T> Key Fields
+| Field | Purpose |
+|-------|---------|
+| `renderer` | Custom cell renderer (wired via columnMapper `def.cell`) |
+| `rendererMeta` | Metadata for built-in renderers (colorMap, max, etc.) |
+| `filterConfig` | `{ type, quickFilter?, enumOptions? }` |
+| `editable` | `boolean \| (row) => boolean` |
+| `editorConfig` | Editor-specific config (options, min, max, etc.) |
+| `pinned` | `'left' \| 'right'` |
+| `headerGroup` | Groups columns under parent header |
+
+## Keyboard Bindings
+- Arrow Up/Down: move focus
+- Page Up/Down: jump by visible page
+- Home/End: first/last row
+- Space: toggle selection
+- Shift+Arrow: extend multi-selection
+- Ctrl+A: select all (multi mode)
+- Ctrl+F: open search overlay
+- Ctrl+E / Enter: enter edit mode
+- Escape: close search / cancel edit / clear selection
+
+## Gotchas / Bugs Fixed
+1. **Hooks violation in VirtualBody**: `useEffect` was after early `return null`. All hooks must run before any conditional return.
+2. **sortingFn crash**: Setting `sortingFn: undefined` explicitly overrides TanStack's auto-detection. Fix: use `accessorKey` for string accessors.
+3. **createSyncStore typing**: Props synced at runtime via `$sync` but TypeScript only sees `GriddyStoreState`. All prop fields must be declared in store state interface.
+4. **useGriddyStore has no .getState()**: Context-based hook, not vanilla zustand. Use `useRef` for imperative access.
+5. **globalFilterFn: undefined breaks search**: Explicitly setting `globalFilterFn: undefined` disables global filtering. Use conditional spread: `...(advancedSearch?.enabled ? { globalFilterFn } : {})`.
+6. **Custom renderers not rendering**: `columnMapper.ts` must wire `GriddyColumn.renderer` into TanStack's `ColumnDef.cell`.
+7. **Error boundary retry timing**: `onRetry` parent setState must flush before error boundary clears. Use `setTimeout(0)` to defer `setState({ error: null })`.
+8. **ColumnFilterButton must forwardRef**: Mantine's `Popover.Target` requires child to forward refs.
+9. **Filter popover click propagation**: Clicking filter icon bubbles to header cell (triggers sort). Fix: explicit `onClick` with `stopPropagation` on ColumnFilterButton, not relying on Mantine Popover.Target auto-toggle.
+10. **header.getAfter('right')**: Method exists on `Column`, not `Header`. Use `header.column.getAfter('right')`.
+
+## UI Components
+Uses **Mantine** components:
+- `Checkbox`, `TextInput`, `ActionIcon`, `Popover`, `Menu`, `Button`, `Group`, `Stack`, `Text`
+- `Select`, `MultiSelect`, `NumberInput`, `Radio`, `SegmentedControl`, `ScrollArea`
+- `@mantine/dates` for DatePickerInput
+- `@tabler/icons-react` for icons
+
+## Implementation Status
+- [x] Phase 1-9: Core, virtualization, selection, search, filtering, editing, pagination, advanced features, polish
+- [x] Phase 7.5: Infinite scroll
+- [x] Phase 8 completion: Column pinning, header grouping, data grouping, column reordering
+- [x] Phase 10 (partial): Error boundary, loading states, custom renderers, quick filters, advanced search, filter presets, search history
+- [ ] Phase 10 remaining: See plan.md
+
+## E2E Tests
+- **34 total Playwright tests** (8 filtering + 26 feature tests)
+- All passing against Storybook at `http://localhost:6006`
+- Run: `npx playwright test` (requires Storybook running)
+
+## Commands
+```bash
+pnpm run typecheck && pnpm run build   # Build check
+pnpm run storybook                      # Start Storybook
+npx playwright test                     # Run E2E tests
+npx playwright test tests/e2e/griddy-features.spec.ts  # Phase 10 tests only

+  {
+    id: 'name',
+    accessor: 'name',
+    header: 'Name',
+    editable: true,
+    editorConfig: { type: 'text' },

+    header: 'Age',
+    editable: true,
+    editorConfig: { type: 'number', min: 0, max: 120 },
+  },
+]
+
+<Griddy
+  columns={editableColumns}
+  data={data}
+  onEditCommit={(rowId, columnId, value) => {
+    // Update your data
+    setData(prev => prev.map(row =>
+      row.id === rowId ? { ...row, [columnId]: value } : row
+    ))
+  }}
+/>
+```
+
+### With Filtering
+
+```typescript
+const filterableColumns: GriddyColumn<Person>[] = [
+  {
+    id: 'name',
+    accessor: 'name',
+    header: 'Name',
+    filterable: true,
+    filterConfig: { type: 'text' },
+  },
+  {
+    id: 'age',
+    accessor: 'age',
+    header: 'Age',
+    filterable: true,
+    filterConfig: { type: 'number' },
+  },
+]
+
+<Griddy
+  columns={filterableColumns}
+  data={data}
+  columnFilters={filters}
+  onColumnFiltersChange={setFilters}
+/>
+```
+
+### With Pagination
+
+```typescript
+<Griddy
+  columns={columns}
+  data={data}
+  pagination={{
+    enabled: true,
+    pageSize: 25,
+    pageSizeOptions: [10, 25, 50, 100],
+  }}
+/>
+```
+
+### Server-Side Mode
+
+```typescript
+const [serverData, setServerData] = useState([])
+const [filters, setFilters] = useState([])
+const [sorting, setSorting] = useState([])
+
+useEffect(() => {
+  // Fetch from server when filters/sorting change
+  fetchData({ filters, sorting }).then(setServerData)
+}, [filters, sorting])
+
+<Griddy
+  columns={columns}
+  data={serverData}
+  manualFiltering
+  manualSorting
+  columnFilters={filters}
+  onColumnFiltersChange={setFilters}
+  sorting={sorting}
+  onSortingChange={setSorting}
+/>
+```
+
+## Theming
+
+Griddy uses CSS variables for theming:
+
+```css
+.griddy {
+  --griddy-font-family: inherit;
+  --griddy-font-size: 14px;
+  --griddy-border-color: #e0e0e0;
+  --griddy-header-bg: #f8f9fa;
+  --griddy-header-color: #212529;
+  --griddy-row-bg: #ffffff;
+  --griddy-row-hover-bg: #f1f3f5;
+  --griddy-row-even-bg: #f8f9fa;
+  --griddy-focus-color: #228be6;
+  --griddy-selection-bg: rgba(34, 139, 230, 0.1);
+}
+```
+
+Override in your CSS:
+
+```css
+.my-custom-grid {
+  --griddy-focus-color: #ff6b6b;
+  --griddy-header-bg: #1a1b1e;
+  --griddy-header-color: #ffffff;
+}
+```
+

+# Tree/Hierarchical Data Feature - Implementation Summary
+
+## Overview
+
+Successfully implemented complete tree/hierarchical data support for Griddy, enabling the display and interaction with nested data structures like organization charts, file systems, and category hierarchies.
+
+## ✅ Completed Features
+
+### 1. Core Types & Configuration (Phase 1)
+- **TreeConfig<T> interface** added to `types.ts` with comprehensive configuration options
+- **Tree state** added to GriddyStore (loading nodes, children cache, setter methods)
+- **Props integration** - `tree` prop added to GriddyProps
+
+### 2. Data Transformation Layer (Phase 2)
+- **transformTreeData.ts**: Utilities for transforming flat data to nested structure
+  - `transformFlatToNested()` - Converts flat arrays with parentId to nested tree
+  - `hasChildren()` - Determines if a node can expand
+  - `insertChildrenIntoData()` - Helper for lazy loading to update data array
+- **useTreeData.ts**: Hook that transforms data based on tree mode (nested/flat/lazy)
+
+### 3. UI Components (Phase 3)
+- **TreeExpandButton.tsx**: Expand/collapse button component
+  - Shows loading spinner during lazy fetch
+  - Supports custom icons (expanded/collapsed/leaf)
+  - Handles disabled states
+- **TableCell.tsx modifications**:
+  - Added tree indentation based on depth (configurable indentSize)
+  - Renders TreeExpandButton in first column
+  - Proper integration with existing grouping expand buttons
+
+### 4. Lazy Loading (Phase 4)
+- **useLazyTreeExpansion.ts**: Hook for on-demand child fetching
+  - Monitors expanded state changes
+  - Calls `getChildren` callback when node expands
+  - Updates cache and data array with fetched children
+  - Shows loading spinner during fetch
+
+### 5. Keyboard Navigation (Phase 5)
+- **Extended useKeyboardNavigation.ts**:
+  - **ArrowLeft**: Collapse expanded node OR move to parent if collapsed
+  - **ArrowRight**: Expand collapsed node OR move to first child if expanded
+  - Helper function `findParentRow()` for walking up the tree
+  - Auto-scroll focused row into view
+
+### 6. Search Auto-Expand (Phase 6)
+- **useAutoExpandOnSearch.ts**: Automatically expands parent nodes when search matches children
+  - Watches `globalFilter` changes
+  - Builds ancestor chain for matched rows
+  - Expands all ancestors to reveal matched nodes
+  - Configurable via `autoExpandOnSearch` option (default: true)
+
+### 7. TanStack Table Integration (Phase 7)
+- **Griddy.tsx modifications**:
+  - Integrated `useTreeData` hook for data transformation
+  - Configured `getSubRows` for TanStack Table
+  - Added `useLazyTreeExpansion` and `useAutoExpandOnSearch` hooks
+  - Passed tree config to keyboard navigation
+
+### 8. CSS Styling (Phase 8)
+- **griddy.module.css additions**:
+  - `.griddy-tree-expand-button` - Button styles with hover states
+  - Loading and disabled states
+  - Optional depth visual indicators (colored borders)
+  - Focus-visible outline for accessibility
+
+### 9. Documentation & Examples (Phase 10)
+- **6 Comprehensive Storybook stories**:
+  1. **TreeNestedMode**: Basic nested tree with departments → teams → people
+  2. **TreeFlatMode**: Same data as flat array with parentId, auto-transformed
+  3. **TreeLazyMode**: Async children fetching with loading spinner
+  4. **TreeWithSearch**: Search auto-expands parent chain to reveal matches
+  5. **TreeCustomIcons**: Custom expand/collapse/leaf icons (folder emojis)
+  6. **TreeDeepWithMaxDepth**: Deep tree (5 levels) with maxDepth enforcement
+
+## 🎯 API Overview
+
+### TreeConfig Interface
+
+```typescript
+interface TreeConfig<T> {
+  enabled: boolean;
+  mode?: 'nested' | 'flat' | 'lazy'; // default: 'nested'
+
+  // Flat mode
+  parentIdField?: keyof T | string; // default: 'parentId'
+
+  // Nested mode
+  childrenField?: keyof T | string; // default: 'children'
+
+  // Lazy mode
+  getChildren?: (parent: T) => Promise<T[]> | T[];
+  hasChildren?: (row: T) => boolean;
+
+  // Expansion state
+  defaultExpanded?: Record<string, boolean> | string[];
+  expanded?: Record<string, boolean>;
+  onExpandedChange?: (expanded: Record<string, boolean>) => void;
+
+  // UI configuration
+  autoExpandOnSearch?: boolean; // default: true
+  indentSize?: number; // default: 20px
+  maxDepth?: number; // default: Infinity
+  showExpandIcon?: boolean; // default: true
+  icons?: {
+    expanded?: ReactNode;
+    collapsed?: ReactNode;
+    leaf?: ReactNode;
+  };
+}
+```
+
+### Usage Examples
+
+#### Nested Mode (Default)
+```tsx
+<Griddy
+  data={nestedData} // Data with children arrays
+  columns={columns}
+  tree={{
+    enabled: true,
+    mode: 'nested',
+    childrenField: 'children',
+    indentSize: 24,
+  }}
+/>
+```
+
+#### Flat Mode
+```tsx
+<Griddy
+  data={flatData} // Data with parentId references
+  columns={columns}
+  tree={{
+    enabled: true,
+    mode: 'flat',
+    parentIdField: 'parentId',
+  }}
+/>
+```
+
+#### Lazy Mode
+```tsx
+<Griddy
+  data={rootNodes}
+  columns={columns}
+  tree={{
+    enabled: true,
+    mode: 'lazy',
+    getChildren: async (parent) => {
+      const response = await fetch(`/api/children/${parent.id}`);
+      return response.json();
+    },
+    hasChildren: (row) => row.hasChildren,
+  }}
+/>
+```
+
+#### With Search Auto-Expand
+```tsx
+<Griddy
+  data={treeData}
+  columns={columns}
+  search={{ enabled: true, highlightMatches: true }}
+  tree={{
+    enabled: true,
+    autoExpandOnSearch: true, // Auto-expand parents when searching
+  }}
+/>
+```
+
+#### Custom Icons
+```tsx
+<Griddy
+  data={treeData}
+  columns={columns}
+  tree={{
+    enabled: true,
+    icons: {
+      expanded: <IconChevronDown />,
+      collapsed: <IconChevronRight />,
+      leaf: <IconFile />,
+    },
+  }}
+/>
+```
+
+## 🎹 Keyboard Shortcuts
+
+| Key | Action |
+|-----|--------|
+| **ArrowRight** | Expand collapsed node OR move to first child |
+| **ArrowLeft** | Collapse expanded node OR move to parent |
+| **ArrowUp/Down** | Navigate between rows (standard) |
+| **Space** | Toggle row selection (if enabled) |
+| **Ctrl+F** | Open search (auto-expands on match) |
+
+## 🏗️ Architecture Highlights
+
+### Data Flow
+1. **Data Input** → `useTreeData` → Transforms based on mode
+2. **Transformed Data** → TanStack Table `getSubRows`
+3. **Expand Event** → `useLazyTreeExpansion` → Fetch children (lazy mode)
+4. **Search Event** → `useAutoExpandOnSearch` → Expand ancestors
+5. **Keyboard Event** → `useKeyboardNavigation` → Collapse/expand/navigate
+
+### Performance
+- **Virtualization**: Only visible rows rendered (TanStack Virtual)
+- **Memoization**: `useTreeData` memoizes transformations
+- **Lazy Loading**: Children fetched only when needed
+- **Cache**: Fetched children cached in store to avoid re-fetch
+
+### Integration with Existing Features
+- ✅ Works with **sorting** (sorts within each level)
+- ✅ Works with **filtering** (filters all levels)
+- ✅ Works with **search** (auto-expands to reveal matches)
+- ✅ Works with **selection** (select any row at any level)
+- ✅ Works with **editing** (edit any row at any level)
+- ✅ Works with **pagination** (paginate flattened tree)
+- ✅ Works with **grouping** (can use both simultaneously)
