# Story 14.1: Redesign Admin Dashboard Layout

Status: review

<!-- Note: Validation is optional. Run validate-create-story for quality check before dev-story. -->

## Story

As an **administrator**,
I want **a clean, modern admin dashboard layout with improved organization**,
so that **I can manage the application efficiently**.

## Acceptance Criteria

1. Given I am accessing the admin dashboard on desktop
   When I view the dashboard
   Then I should see a sidebar navigation with: Dashboard, Users, AI Management, Settings
2. And I should see a main content area with: metrics, charts, and tables
3. And the layout should be responsive (adapt to different screen sizes)
4. And I should be able to navigate between sections easily

## Dev Notes

### Relevant Architecture Patterns and Constraints

**Design System Integration (Epic 10):**
- Must follow Design System patterns established in Epic 10
- Use existing Radix UI components (@radix-ui/react-*)
- Follow Tailwind CSS 4 conventions for styling
- Consistent color palette from design tokens

**Admin Dashboard Patterns:**
- Target resolution: 1024px+ desktop, 640px-1023px tablet
- Navigation: Sidebar with main sections
- Content area: Metrics, charts, tables
- Visual indicator for active section (highlight/bold)

**Layout Patterns:**
- Flexbox for main layout (sidebar + content area)
- Responsive breakpoints: 640px (tablet min), 1024px (desktop min)
- Consistent 4px base unit spacing
- Grid layout for metrics display

**Component Patterns:**
- Use existing Card component from Design System (metrics)
- Use existing Button component from Design System
- Use existing Badge component for status
- Use existing Table component for data display

**Authentication & Authorization:**
- Must check user has admin role (NextAuth session)
- Protect admin routes with middleware
- Display unauthorized message if not admin

### Source Tree Components to Touch

**Files to Modify:**
```
keep-notes/app/(main)/admin/page.tsx
  - Main admin dashboard page
  - Update to use new layout structure

keep-notes/app/(main)/admin/layout.tsx
  - Admin layout wrapper

  - NEW: Sidebar component for admin navigation
  - Implement navigation links: Dashboard, Users, AI Management, Settings

keep-notes/components/admin-content-area.tsx
  - NEW: Main content area component
  - Display metrics, charts, tables
  - Implement responsive grid layout

keep-notes/components/admin-metrics.tsx
  - NEW: Metrics display component
  - Show key metrics with Card components
  - Display trend indicators

keep-notes/app/(main)/admin/users/page.tsx
  - NEW: Users management page
  - Display users table
  - Implement user management actions

keep-notes/app/(main)/admin/ai/page.tsx
  - NEW: AI management page
  - Display AI usage metrics
  - Configure AI settings

keep-notes/app/(main)/admin/settings/page.tsx
  - NEW: Admin settings page
  - Display application settings
  - Configure system-wide settings
```

**Authentication Files:**
```
keep-notes/middleware.ts
  - Add admin route protection
  - Check for admin role

keep-notes/app/actions/admin.ts
  - Existing admin server actions
  - May need extensions for new features
```

**Existing Admin Components:**
```
keep-notes/components/admin-dashboard.tsx
  - Existing admin dashboard (refactor if needed)
  - Preserve existing functionality

keep-notes/components/user-table.tsx
  - Existing user table component (if exists)
  - Integrate into new layout
```

### Testing Standards Summary

**Manual Testing:**
- Test on desktop (1024px+)
- Test on tablet (640px-1023px)
- Test navigation between all admin sections
- Test visual indicator for active section
- Test responsive design at breakpoints

**Authentication Testing:**
- Test with admin user (access allowed)
- Test with non-admin user (access denied)
- Test with unauthenticated user (redirect to login)

**Accessibility Testing:**
- Keyboard navigation (Tab order logical, focus indicators visible)
- Screen reader compatibility (NVDA, VoiceOver)
- Contrast ratios (WCAG 2.1 AA: 4.5:1 for text)
- Touch targets (minimum 44x44px for interactive elements)

**E2E Testing (Playwright):**
- Tests in `tests/e2e/admin-dashboard.spec.ts`
- Test admin authentication flow
- Test navigation between sections
- Test responsive layout at breakpoints
- Test user management actions
- Test AI management features

### Project Structure Notes

**Alignment with Unified Project Structure:**

✅ **Follows App Router Patterns:**
- Admin routes in `app/(main)/admin/` directory
- Component files in `components/` (kebab-case)
- Use `'use client'` directive for interactive components

✅ **Follows Design System Patterns:**
- Components in `components/ui/` (Radix UI primitives)
- Use existing Button, Card, Badge, Dialog, Table components
- Tailwind CSS 4 for styling

✅ **Follows Naming Conventions:**
- PascalCase component names: `AdminSidebar`, `AdminContentArea`, `AdminMetrics`
- camelCase function names: `getAdminData`, `handleNavigation`
- kebab-case file names: `admin-sidebar.tsx`, `admin-content-area.tsx`

✅ **Follows Response Format:**
- API responses: `{success: true|false, data: any, error: string}`
- Server Actions: Return `{success, data}` or throw Error
- Error handling: try/catch with console.error()

**Potential Conflicts or Variances:**

⚠️ **Admin Authentication Needed:**
- Must implement admin role check in middleware
- May need to extend User model with admin role field
- Protect all admin routes (Dashboard, Users, AI, Settings)

⚠️ **Existing Admin Dashboard:**
- Existing admin dashboard component may need refactoring
- Must preserve existing functionality during redesign
- Ensure zero breaking changes to admin features

⚠️ **Navigation Complexity:**
- Admin sections may have nested sub-sections
- Need to handle nested navigation states
- Ensure breadcrumbs are implemented (Story 13.6 dependency)

⚠️ **Metrics and Charts:**
- May need to integrate charting library (Chart.js, Recharts)
- Ensure charts are responsive
- Optimize for performance with large datasets
