+# Task: Create Admin Dashboard Component for Thai Voting System
+
+## Summary
+Created the complete admin dashboard component at `/home/z/my-project/src/components/admin-dashboard.tsx` with 5 tabs and updated `page.tsx` to conditionally render it based on the auth store's `currentView`.
+
+## Files Created/Modified
+1. **Created**: `/home/z/my-project/src/components/admin-dashboard.tsx` - Main admin dashboard component (~900 lines)
+2. **Modified**: `/home/z/my-project/src/app/page.tsx` - Added conditional rendering based on auth state
+
+## Component Structure
+
+### Types & Schemas
+- Defined TypeScript interfaces for Branch, Employee, Candidate, BranchStats, Stats, AppSettings
+- Created Zod validation schemas: `branchSchema`, `employeeSchema`, `employeeEditSchema`, `candidateSchema`, `settingsSchema`
+
+### Sub-Components (all within the same file)
+
+1. **StatsTab** - Fetches GET /api/admin/stats, displays:
+   - 5 summary cards (employees, voters, candidates, total votes, participation rate)
+   - Overall participation progress bar
+   - Per-branch statistics table with progress bars
+
+2. **BranchesTab** - Fetches GET /api/admin/branches, features:
+   - Branches table with name, code, employee count
+   - Add branch dialog with form validation (react-hook-form + zod)
+   - Delete branch confirmation (AlertDialog)
+
+3. **EmployeesTab** - Fetches GET /api/admin/employees, features:
+   - Employees table with ID, name, branch, isAdmin badge, isActive badge
+   - Search/filter input for employee lookup
+   - Add employee dialog with full form (ID, name, branch select, PIN, admin toggle)
+   - Edit employee dialog with pre-filled data
+   - Deactivate employee confirmation (AlertDialog)
+   - Badge components for status indicators (emerald for active, red for inactive, amber for admin)
+
+4. **CandidatesTab** - Fetches GET /api/admin/candidates, features:
+   - Candidates table with name, employee code, branch, position, approval status
+   - Add candidate dialog with employee dropdown (auto-filters to non-candidates)
+   - Auto-fills branch when employee is selected
+   - Delete candidate confirmation with warning about vote deletion
+
+5. **SettingsTab** - Fetches GET /api/admin/settings, features:
+   - Form with: system name, max votes per person, voting start/end datetime, voting enabled switch, results visible switch
+   - Proper datetime-local inputs for date fields
+   - Save button with PUT /api/admin/settings
+
+### Design Choices
+- **Color scheme**: Emerald/teal primary, amber accents, red for destructive (NO indigo/blue)
+- **Thai language**: All UI text in Thai
+- **Responsive**: Mobile-first with responsive grids, scrollable tables
+- **Loading states**: Skeleton components for each tab
+- **Error handling**: Toast notifications via sonner for all API operations
+- **Form validation**: react-hook-form with zod resolvers
+
+## Lint & Compilation
+- ESLint passes with no errors
+- Page compiles successfully (200 status)
+- Pre-existing bun:sqlite module error is unrelated to these changes
