🎯 Chosen Vertical: Civic Education & Engagement

Problem: India's complex election process, with its multiple regulatory forms (6, 6A, 6B, 7, 8), state-specific procedures, and frequent administrative changes, creates barriers to civic participation. Citizens struggle to navigate official documentation and understand electoral processes.

Solution: ElectionGuide provides a personalized, AI-powered assistant that:

• Simplifies dense government documentation into conversational guidance
• Provides real-time, grounded responses citing official ECI sources
• Tracks user progress across multiple learning paths
• Offers accessible, inclusive design for all citizens
• Maintains strict security and privacy standards

Impact: By lowering the barrier to civic understanding, ElectionGuide increases voter confidence and participation.

🚀 Approach and Logic

1. AI-First Education with Search Grounding

• Technology: Google Gemini 2.5 Flash with Google Search Grounding
• Why: Instead of static FAQs with stale information, the system queries live data from ECI websites
• How: The chat API (api/chat/route.ts) configures Gemini with tools: [{ googleSearch: {} }]
• Guarantee: Every response is grounded in current, official sources

2. Personalized Learning Path (State Persistence)

• Technology: Google Cloud Firestore with native SDK (@google-cloud/firestore)
• Lazy Initialization: Singleton pattern ensures responsive startup and clean testing
• Progress Tracking: Views, completions, quiz scores stored per user
• Context Enrichment: AI assistant receives user's progress as context for personalized responses
• Backend-First: Firestore operations via src/lib/firestore-admin.ts (never exposed to client)

3. Security by Design

• CSRF Protection: HTTP-only cookies + header validation (x-csrf-token)
• Rate Limiting: IP-based for guests (5 req/min), User ID-based for authenticated (20 req/min)
• Input Validation: Zod schemas on all user inputs (chat messages, quiz submissions)
• No PII Leaks: Firestore Security Rules restrict data access to users' own records

4. Accessibility for All Citizens

• Semantic HTML5: Proper heading hierarchy, landmarks (<main>, <nav>, <section>)
• ARIA Labels: Dynamic content has aria-live="polite" for screen reader users
• Skip-to-Content: Keyboard users can bypass navigation
• Mobile-First Design: Premium hamburger menu on small viewports; responsive Tailwind layout
• Color Contrast: WCAG AA compliance (4.5:1 for text)
• Keyboard Navigation: All interactive elements reachable via Tab/Enter

5. Logical Decision Making

The assistant uses multi-turn context to provide intelligent guidance:

• Step Sequencing: "You've completed voter ID registration. Next, search the electoral roll..."
• State Validation: "You haven't visited the Timeline page yet. I recommend learning the key dates first."
• Personalized Upsell: "As a guest, you're limited to 5 messages/min. Upgrade to unlock unlimited support."

Data Flow Example: Chat Request

1. User types message in chat UI
2. Frontend generates CSRF token, attaches to request
3. API validates: CSRF ✓, Rate Limit ✓, Input Schema ✓
4. Backend fetches user progress from Firestore (context)
5. Constructs grounded prompt: "User is on Step 3 of Voter ID process..."
6. Sends to Gemini with search grounding enabled
7. Gemini searches ECI website, returns grounded response
8. Response streamed back to client
9. User progress updated in Firestore

⚙️ Configuration

Firestore Security Rules

Deploy via Firebase Console:

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    // Users can only read/write their own progress
    match /users/{userId} {
      allow read: if request.auth.uid == userId || request.auth == null;
      allow write: if request.auth.uid == userId;
    }
  }
}

Chat API Rate Limits

Edit src/app/api/chat/route.ts:

const RATE_LIMITS = {
  guest: { requests: 5, windowMs: 60000 },          // 5/min
  authenticated: { requests: 20, windowMs: 60000 }, // 20/min
};

Gemini System Prompt

npm run test:watch             # Watch mode
npm run test:coverage          # Coverage report (target: 90%+)

Coverage Targets:

• Core libraries (src/lib/): 100%
• API routes (src/app/api/): 90%+
• Components: 85%+ (UI behavior, not visuals)

Key Test Files:

• src/lib/__tests__/gemini.test.ts - Gemini client mocking
• src/lib/__tests__/firestore-admin.test.ts - Firestore operations
• src/lib/__tests__/security.test.ts - CSRF, rate limiting
• src/components/__tests__/AuthProvider.test.tsx - Auth context

E2E Tests (Playwright)

npm run test:e2e                # Run all E2E tests
npx playwright test --debug     # Interactive mode
npx playwright test --headed    # Show browser

Coverage Scenarios:

1. Navigation: Landing → Dashboard → Process → Chat → Quiz
2. Chat Flow: Message submission, response streaming, error handling
3. Accessibility: Keyboard navigation, skip-links, ARIA labels
4. Authentication: Guest limits, rate limiting triggers

Example Test (e2e/chat.spec.ts):

test('chat assistant provides grounded response', async ({ page }) => {
  await page.goto('/assistant');
  await page.fill('[aria-label="Chat message input"]', 'How do I register to vote?');
  await page.click('button:has-text("Send")');
  
  // Wait for response
  await page.waitForSelector('text=/Search Grounding|ECI/');
  const response = await page.textContent('[role="article"]');
  expect(response).toContain('ECI'); // Verify grounding
});
