-## Form Patterns
-
-### Basic Form Group
-```jsx
-
-
-
- {error &&
{error}
}
- {success &&
Saved!
}
-
-```
-
-### Form with Card
-```jsx
-
-
- Login
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-```
-
-## Layout Patterns
-
-### Page Layout
-```jsx
-
-
-
- {/* page content */}
-
-
-
-```
-
-### Card Grid
-```jsx
-
- {items.map(item => (
-
- {/* card content */}
-
- ))}
-
-```
-
-### Two Column Layout
-```jsx
-
-
- {/* main content */}
-
-
- {/* sidebar */}
-
-
-```
-
-## Common Patterns
-
-### Alert with Close
-```jsx
-const [showAlert, setShowAlert] = useState(true);
-
-{showAlert && (
-
- Success
- Operation completed
-
-
-)}
-```
-
-### Button Group
-```jsx
-
-
-
-
-```
-
-### Status Badge
-```jsx
-
- Active
- Online
-
-```
-
-### Loading State
-```jsx
-import LoadingSpinner from '../components/LoadingSpinner';
-
-{isLoading &&
}
-{isLoading &&
}
-```
-
-### Empty State
-```jsx
-
-
No items found
-
Create one to get started
-
-
-```
-
-## Responsive Patterns
-
-### Mobile First
-```jsx
-// Base style for mobile, override on larger screens
-className="flex flex-col md:flex-row"
-className="text-sm md:text-base lg:text-lg"
-className="w-full md:w-1/2 lg:w-1/3"
-className="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3"
-```
-
-### Show/Hide on Breakpoint
-```jsx
-className="hidden md:block" // show on medium and up
-className="md:hidden" // hide on medium and up
-className="block lg:hidden" // show except on large
-```
-
-## Performance Tips
-
-1. **Use Tailwind for styling**, not inline styles
-2. **Keep components small** and focused
-3. **Use `className` merging** with `cn()` function for dynamic classes
-4. **Avoid unused Tailwind classes** - Tailwind purges them in production
-5. **Use semantic HTML** with proper heading hierarchy
-6. **Lazy load components** when possible
-
-## Common Issues & Solutions
-
-### Issue: Styles not applying
-**Solution**: Ensure:
-- Tailwind is configured correctly in `tailwind.config.js`
-- CSS is imported in `index.css` with `@tailwind` directives
-- PostCSS is configured in `postcss.config.js`
-
-### Issue: Colors not matching
-**Solution**:
-- Check CSS variables in `:root` of `index.css`
-- Verify Tailwind config has extended colors
-- Use exact class names: `text-text-primary` not `text-primary`
-
-### Issue: Component not styled
-**Solution**:
-- Verify component is imported from `/lib/ui`
-- Check `cn()` utility merges classes correctly
-- Ensure parent has proper `className` applied
-
-## Migration Checklist for New Pages
-
-When creating or refactoring a page:
-
-- [ ] Use ShadCN Button for all actions
-- [ ] Use ShadCN Card for content grouping
-- [ ] Use ShadCN Alert for notifications
-- [ ] Use ShadCN Dialog for modals
-- [ ] Use ShadCN Input for form fields
-- [ ] Use ShadCN Badge for status indicators
-- [ ] Use Tailwind grid for layouts
-- [ ] Use Tailwind for spacing and sizing
-- [ ] Use custom CSS variables for colors
-- [ ] Follow mobile-first responsive design
-- [ ] Test on mobile, tablet, and desktop

-## ๐ฌ Test Execution
-
-### Test 1: Console Log Inspection (5 min)
-
-**Step 1.1**: Open browser
-```
-1. Navigate to: http://localhost:3000/dashboard/blockchain
-2. Press: F12 (or Cmd+Option+I on Mac)
-3. Go to: Console tab
-```
-
-**Step 1.2**: Look for normalization logs
-```javascript
-// You should see something like:
-[BlockchainPage] Fetching blockchain for election: 1
-[BlockchainPage] Response status: 200
-[BlockchainPage] Received blockchain data: {
- blocksCount: 5,
- firstBlockStructure: {
- index: 0,
- prev_hash: "0x000...",
- timestamp: 1234567890,
- encrypted_vote: "0x123...",
- transaction_id: "voter123", โ โ
SHOULD BE STRING!
- block_hash: "0x456...",
- signature: "0x789..."
- }
-}
-```
-
-**Step 1.3**: Check truncateHash logs
-```javascript
-// Should see these (NOT undefined):
-[truncateHash] Called with: {
- hash: "0x123456789abcdef", โ โ
STRING, not OBJECT!
- type: "string",
- isUndefined: false,
- isNull: false,
- isEmpty: false,
- length: 18
-}
-[truncateHash] Result: 0x123456789abcde... โ โ
SUCCESS!
-
-[truncateHash] Called with: {
- hash: "voter123",
- type: "string",
- isUndefined: false,
- ...
-}
-[truncateHash] Result: voter123 โ โ
SUCCESS!
-```
-
-**Expected Result**:
-- โ
NO errors like `truncateHash: invalid hash parameter: undefined`
-- โ
All `type` values are `"string"`, not `"undefined"`
-- โ
All `transaction_id` values are strings (voter IDs or ""), not undefined
-- โ
No `isUndefined: true` entries
-
----
-
-### Test 2: Blockchain Display (2 min)
-
-**Step 2.1**: Visual inspection
-```
-1. Look at blockchain visualization
-2. Should see:
- - Multiple blocks displayed
- - Each block shows transaction_id (voter ID or empty for genesis)
- - Hash values are visible and truncated nicely
- - No "N/A" for all fields
-```
-
-**Step 2.2**: Block details
-```
-Click on any block โ Should show:
- โ
Transaction ID: voter123 (or similar)
- โ
Encrypted Vote: 0x123456... (truncated)
- โ
Block Hash: 0x789abc... (truncated)
- โ
Signature: 0xdef456... (truncated)
-
-โ
NO "N/A" for any hash field
-โ
NO undefined errors in console
-```
-
----
-
-### Test 3: Verify Button Functionality (2 min)
-
-**Step 3.1**: Click Verify Button
-```
-1. Click: "Vรฉrifier l'intรฉgritรฉ de la chaรฎne" button
-2. Check Network tab (Ctrl+Shift+E)
-3. Should see: POST to /api/votes/verify-blockchain
-```
-
-**Step 3.2**: Check request parameters
-```
-Request URL: .../api/votes/verify-blockchain?election_id=1
-Request Body: { "election_id": 1 }
-
-โ
election_id is in URL query parameters
-โ
election_id is in request body
-โ
NOT getting 400 error
-```
-
-**Step 3.3**: Check verification result
-```
-Response should be 200 OK with:
-{
- "chain_valid": true/false,
- "total_blocks": 5,
- "total_votes": 4,
- "issues": [...]
-}
-
-โ
NO 400 "Field required: election_id" error
-โ
Verification completes without error
-```
-
----
-
-## โ
Success Criteria
-
-### All Should Be TRUE:
-
-| Criterion | Check |
-|-----------|-------|
-| **No truncateHash errors in console** | Clear console, no red errors |
-| **transaction_id is always a string** | Search console for `"string"` values |
-| **No OBJECT values for hashes** | No `{...}` in transaction_id fields |
-| **Blockchain displays correctly** | Visual layout is intact, readable |
-| **Verify button works** | Returns 200 OK, no 400 errors |
-| **All hash fields visible** | No "N/A" for populated fields |
-
----
-
-## ๐ Troubleshooting
-
-### If You See: `truncateHash: invalid hash parameter: undefined`
-```
-Problem: Backend normalization not running
-Solution:
-1. Stop backend: docker compose stop backend
-2. Start backend: docker compose start backend
-3. Wait 5 seconds
-4. Hard refresh browser: Ctrl+F5 (or Cmd+Shift+R on Mac)
-5. Retry test
-```
-
-### If transaction_id Still Shows as OBJECT
-```
-Problem: Old cached response
-Solution:
-1. Clear browser cache: Ctrl+Shift+Delete
-2. Close all browser tabs for localhost:3000
-3. Restart browser
-4. Navigate to fresh URL
-5. Press F12, then reload: Ctrl+R or F5
-```
-
-### If Verify Button Returns 400 Error
-```
-Problem: election_id not being passed
-Solution:
-1. Check proxy route is modified:
- /frontend/app/api/votes/verify-blockchain/route.ts
-2. Ensure election_id parameter is added to URL
-3. Check Network tab request includes ?election_id=X
-```
-
-### If Blockchain Doesn't Display At All
-```
-Problem: Backend might have crashed
-Solution:
-1. Check backend logs: docker compose logs backend
-2. Look for Python errors
-3. Restart: docker compose restart backend
-4. Refresh browser: F5
-```
-
----
-
-## ๐ Expected Console Output
-
-### Good Signs โ

-TypeError: Cannot read property 'transaction_id' of undefined
-```
-
----
-
-## ๐ Deep Inspection Commands
-
-### In Browser Console:
-
-**Check first block structure**:
-```javascript
-// After page loads, copy-paste this:
-console.log('First block:', JSON.stringify(blocks[0], null, 2))
-```
-
-**Check all transaction_ids**:
-```javascript
-blocks.forEach((block, i) => {
- console.log(`Block ${i}: transaction_id = ${block.transaction_id} (type: ${typeof block.transaction_id})`)
-})
-```
-
-**Check if normalization worked**:
-```javascript
-// Should print TRUE if normalized
-blocks.every(b => typeof b.transaction_id === 'string' || b.transaction_id === undefined)
-```
-
-**Verify hash values**:
-```javascript
-blocks.forEach((block, i) => {
- console.log(`Block ${i}:`, {
- transaction_id_type: typeof block.transaction_id,
- encrypted_vote_type: typeof block.encrypted_vote,
- block_hash_type: typeof block.block_hash,
- signature_type: typeof block.signature
- })
-})

-# ๐ Quick Start - Test the Enhanced Logging
-
-**Time needed**: 5 minutes
-**What you'll do**: Add logging, rebuild, check console
-**Goal**: Find the source of undefined hash error
-
----
-
-## Step 1: Verify Files Were Modified โ
-
-```bash
-# Check if logging code is in place
-grep -l "\[BlockchainVisualizer\]" /home/paul/CIA/e-voting-system/frontend/components/blockchain-visualizer.tsx
-
-# Should output: /home/paul/CIA/e-voting-system/frontend/components/blockchain-visualizer.tsx
-```
-
-Expected: File found โ
-
----
-
-## Step 2: Rebuild Frontend
-
-```bash
-cd /home/paul/CIA/e-voting-system
-
-# Restart the frontend container
-docker compose restart frontend
-
-# Wait for it to be ready
-sleep 5
-
-echo "โ
Frontend restarted with new logging"
-```
-
-Expected: No errors, frontend running โ
-
----
-
-## Step 3: Open Your Browser
-
-1. **Open browser** (Chrome, Firefox, Edge, etc.)
-2. **Go to**: `http://localhost:3000/dashboard/blockchain`
-3. **Press F12** to open Developer Tools
-4. **Click "Console" tab**
-
-Expected: Page loads, console is open โ
-
----
-
-## Step 4: Select an Election
-
-1. **Look for dropdown** with election names
-2. **Click on it** (e.g., "Election Prรฉsidentielle 2025")
-3. **Wait** for blockchain to load (5-10 seconds)
-4. **Watch the Console** for logs
-
-Expected: Logs appear in console โ
-
----
-
-## Step 5: Look for Your Logs
-
-### Search in Console:
-Press `Ctrl+F` and search for: `[truncateHash]`
-
-### You should see output like:
-```
-[BlockchainPage] Fetching blockchain for election: 1
-[BlockchainPage] Fetch response status: 200
-[BlockchainPage] Received blockchain data: { blocksCount: 5, ... }
-[BlockchainVisualizer] Component mounted/updated { dataExists: true, ... }
-[truncateHash] Called with: { hash: "genesis", type: "string", ... }
-[truncateHash] Result: genesis
-[truncateHash] Called with: { hash: "", type: "string", isEmpty: true, ... }
-[truncateHash] Empty string received
-[truncateHash] Result: N/A
-```
-
----
-
-## Step 6: Check for the Problem
-
-### Look for any of these problematic entries:
-```
-[truncateHash] Called with: { hash: undefined, type: "undefined", isUndefined: true, ... }
-[truncateHash] Received undefined
-```
-
-### What this means:
-- โ
**If NOT found**: The fix is working! No undefined values
-- โ **If FOUND**: Still getting undefined from somewhere
-
----
-
-## Step 7: Copy the Full Console Output
-
-1. **Right-click in console**
-2. **Click "Save as..."**
-3. **Save to file** like `console-output.txt`
-
-**OR** manually copy all logs:
-1. **Select all** in console with `Ctrl+A`
-2. **Copy** with `Ctrl+C`
-3. **Paste** into text editor
-
----
-
-## ๐ What Each Log Tells You
-
-| Log | Means |
-|-----|-------|
-| `[BlockchainPage] Fetching...` | Data is being fetched from backend โ
|
-| `Fetch response status: 200` | Backend returned data successfully โ
|
-| `[BlockchainVisualizer] Component mounted` | React component is rendering โ
|
-| `First block structure: { transaction_id: "genesis"... }` | Data has values โ
|
-| `First block structure: { transaction_id: undefined... }` | โ Data is corrupted! |
-| `[truncateHash] Called with: { hash: "abc"... }` | Working on valid hash โ
|
-| `[truncateHash] Called with: { hash: undefined... }` | โ Receiving undefined! |
-| `[truncateHash] Result: N/A` | Handled empty/undefined gracefully โ

}
-
-```
-
-### Links
-```jsx
-
- Link Text
-
-
-// With underline
-
- Link Text
-
-```
-
-## Implementation Order Recommendation
-
-1. **LoginPage** โ
(Completed)
-2. **RegisterPage** (Similar to LoginPage)
-3. **HomePage** (High visibility, marketing)
-4. **DashboardPage** (Central hub)
-5. **VotingPage** (Core functionality)
-6. **ElectionDetailsModal** (Used in multiple places)
-7. Remaining pages (ActiveVotesPage, UpcomingVotesPage, etc.)
-8. **ProfilePage** (Lower priority)
-
-## Color Accessibility
-
-The theme uses:
-- **Contrast ratios**: Text meets WCAG AA standards (at least 4.5:1)
-- **Semantic colors**: Red/Green/Yellow for status (not color-blind unfriendly)
-- **Focus states**: All interactive elements have visible focus rings (ring-2 ring-accent-warm)
-
-## Mobile-First Approach
-
-Always use mobile-first Tailwind:
-```jsx
-// Mobile by default, larger on screens
-className="text-sm md:text-base lg:text-lg" // Text size
-className="grid grid-cols-1 md:grid-cols-2" // Layout
-className="px-4 md:px-6 lg:px-8" // Spacing
-className="hidden md:block" // Visibility
-```
-
-## Performance Tips
-
-1. **Use Tailwind utilities** instead of custom CSS
-2. **Avoid inline styles** - use className
-3. **Lazy load images** when possible
-4. **Use Next.js Image** component if upgrading to Next.js
-5. **Memoize expensive components** with React.memo
-
-## Testing Theme
-
-Once refactoring is complete:
-
-```bash
-# Build the project
-npm run build
-
-# Test locally
-npm install -g serve
-serve -s build
-
-# Check on mobile (localhost:3000)
-```

-# Troubleshooting Guide
-
-## Issue: 404 on `/api/elections/active`
-
-### Diagnosis
-
-First, check what's actually in the database:
-
-```bash
-# Check all elections
-curl http://localhost:8000/api/elections/debug/all
-
-# Example response:
-{
- "current_time": "2025-11-07T03:45:00.123456",
- "elections": [
- {
- "id": 1,
- "name": "Election Prรฉsidentielle 2025",
- "is_active": true,
- "start_date": "2025-11-06T02:45:00",
- "end_date": "2025-11-14T02:45:00",
- "should_be_active": true โ Should be TRUE
- },
- {
- "id": 2,
- "name": "Prรฉsidentielle 2020",
- "is_active": false,
- "start_date": "2020-04-10T08:00:00",
- "end_date": "2020-04-10T20:00:00",
- "should_be_active": false
- }
- ]
-}
-```
-
-### Solution
-
-If no elections show `should_be_active: true`, follow these steps:
-
-#### Option 1: Fresh Database (Recommended)
-
-```bash
-# Stop containers
-docker-compose down
-
-# DELETE the database volume
-docker-compose down -v
-
-# Start fresh (will reinitialize)
-docker-compose up -d
-
-# Wait 30 seconds for database to initialize
-sleep 30
-
-# Verify elections were created
-curl http://localhost:8000/api/elections/debug/all
-
-# Now test active elections
-curl http://localhost:8000/api/elections/active
-```
-
-#### Option 2: Manually Fix via Adminer
-
-1. Go to http://localhost:8081
-2. Login:
- - Server: `mariadb`
- - User: `evoting_user`
- - Password: `evoting_pass123`
- - Database: `evoting_db`
-
-3. Run SQL in Adminer:
- ```sql
- -- Update election 1 to be active
- UPDATE elections
- SET
- is_active = 1,
- start_date = DATE_SUB(NOW(), INTERVAL 1 HOUR),
- end_date = DATE_ADD(NOW(), INTERVAL 7 DAY)
- WHERE id = 1;
-
- -- Verify it worked
- SELECT id, name, is_active, start_date, end_date FROM elections LIMIT 5;
- ```
-
-4. Test API:
- ```bash
- curl http://localhost:8000/api/elections/active
- ```
-
-#### Option 3: Direct Database Command
-
-```bash
-# Connect to MariaDB in Docker
-docker-compose exec mariadb mariadb -u evoting_user -pevoting_pass123 evoting_db
-
-# Run this SQL:
-UPDATE elections
-SET
- is_active = 1,
- start_date = DATE_SUB(NOW(), INTERVAL 1 HOUR),
- end_date = DATE_ADD(NOW(), INTERVAL 7 DAY)
-WHERE id = 1;
-
-# Exit (Ctrl+D)
-
-# Test:
-curl http://localhost:8000/api/elections/active
-```
-
-### Root Cause
-
-The 404 occurs when:
-- No elections exist in database
-- All elections have `is_active = FALSE`
-- All elections have dates in the past (`end_date < NOW()`)
-- All elections have dates in the future (`start_date > NOW()`)
-
-The database initialization scripts should handle this, but if they don't:
-1. `docker/init.sql` creates 1 active election (ID 1)
-2. `docker/populate_past_elections.sql` creates 10 past elections (IDs 2-11)
-3. `docker/create_active_election.sql` ensures election 1 is always active
-
-If still getting 404 after these scripts run, use the manual fixes above.
-
----
-
-## Issue: Empty Elections List on Frontend
-
-If `/api/elections/active` returns `[]` (empty list):
-
-### Check 1: Database has active elections
-```bash
-curl http://localhost:8000/api/elections/debug/all
-```
-
-### Check 2: Timezone issues
-- Docker database might be in different timezone
-- The endpoint now includes **1-hour buffer** on both sides to handle timezone skew
-- If still failing, the election dates are probably way off
-
-### Check 3: Frontend not fetching
-Open browser console (F12):
-```bash
-# Should show the fetch request
-GET http://localhost:3000/api/elections/active
-```
-
-If it's calling the **frontend** API instead of backend:
-- Frontend routes requests through its own API route
-- Check `frontend/lib/api.ts` for correct backend URL
-- Verify `NEXT_PUBLIC_API_URL` environment variable
-
----
-
-## Issue: Vote Submission Fails
-
-### Error: "Impossible de charger les clรฉs publiques"
-
-Election doesn't have ElGamal keys. Fix:
-```sql
-UPDATE elections
-SET elgamal_p = 23, elgamal_g = 5
-WHERE elgamal_p IS NULL OR elgamal_g IS NULL;
-```
-
-### Error: "Voter has already voted in this election"
-
-Voter already voted. To reset (for testing):
-```sql
-DELETE FROM votes WHERE voter_id = 1; -- Replace 1 with voter ID
-UPDATE voters SET has_voted = FALSE WHERE id = 1;
-```
-
-### Error: "Candidate not found"
-
-Candidate doesn't exist for election. Check:
-```sql
-SELECT c.id, c.name, c.election_id
-FROM candidates c
-WHERE c.election_id = 1; -- Replace 1 with election ID
-```
-
----
-
-## Issue: Blockchain Not Showing Votes
-
-### Check: Votes recorded in database
-```sql
-SELECT COUNT(*) FROM votes;
-SELECT * FROM votes LIMIT 5;
-```
-
-### Check: Blockchain endpoint accessible
-```bash
-curl http://localhost:8000/api/votes/blockchain?election_id=1
-```
-
-### If no blocks:
-- Votes might be in database but blockchain not synced
-- Restart backend to reinitialize blockchain
-```bash
-docker-compose restart backend
-```
-
----
-
-## Issue: Docker Container Won't Start
-
-### Check logs
-```bash
-docker-compose logs mariadb
-docker-compose logs backend
-docker-compose logs frontend
-```
-
-### Database won't start
-```bash
-# Check if port 3306 is already in use
-lsof -i :3306
-
-# Or check Docker volume issue
-docker volume ls
-docker volume rm evoting_data
-docker-compose up -d
-```
-
-### Backend won't connect to database
-Wait longer for MariaDB to start:
-```bash
-docker-compose up mariadb
-# Wait until you see: "ready for connections"
-# Then in another terminal:
-docker-compose up backend frontend
-```
-
----
-
-## Debugging Checklist
-
-- [ ] Database initialized? `curl http://localhost:8000/api/elections/debug/all`
-- [ ] Active elections exist? Check response shows `"should_be_active": true`
-- [ ] Backend running? `docker-compose ps` shows `backend` healthy
-- [ ] Frontend built? `npm run build` succeeded with 0 errors
-- [ ] Elections endpoint returns data? `curl http://localhost:8000/api/elections/active`
-- [ ] Frontend can fetch? Check browser console for network requests
-- [ ] Votes can be submitted? Test via voting interface
-- [ ] Blockchain records votes? Check `/dashboard/blockchain`
-
----
-
-## Quick Reset
-
-If everything is broken:
-
-```bash
-# Stop everything
-docker-compose down
-
-# Remove all data
-docker-compose down -v
-
-# Fresh start
-docker-compose up -d
-
-# Wait for initialization
-sleep 30
-
-# Check status
-curl http://localhost:8000/api/elections/debug/all
-curl http://localhost:8000/api/elections/active
-
-# Should be good now!
-```
-
----
-
-## Contact Info
-
-For issues not covered here:
-- Check Docker logs: `docker-compose logs -f`

-
-### ๐ค Already Voted Voter
-
-```
-BEFORE (Confusing):
-1. Click election
-2. See election details
-3. See vote done message
-4. See voting form (WHAT?!)
-5. Think: "Can I vote again?"
-6. Back up and confused
-
-โ Not ideal UX

-
-### Complexity Reduction
-
-```
-Before: Conditional rendering with nested ternaries
- {!hasVoted && election.is_active ? (
-
- ) : hasVoted ? (
-
- ) : (
-
- )}
-

-## The Solution
-
-Created: `/frontend/app/api/votes/check/route.ts`

-
----
-
-## After (โ
Fixed)
-
-```
-User visits voting page
- โ
-Page load
- โ
-Try: GET /api/votes/check?election_id=1
- โ
-Frontend proxy: "Let me forward this to backend..."
- โ
-Backend: "Query database... User has not voted"
- โ
-Response: { "has_voted": false } โ
- โ
-Frontend: "Show voting form" โ
-```
-
----
-
-## What Happens on Page Load
-
-### Scenario 1: User Hasn't Voted Yet
-
-```
-1. Visit: /dashboard/votes/active/1

-
-### Scenario 2: User Already Voted
-
-```
-1. Visit: /dashboard/votes/active/1
-2. Page loads
-3. Check vote status: /api/votes/check?election_id=1

----
-
-## What Already Existed
-
-โ
Backend has: `/api/votes/check` (lines 766-791 of votes.py)
-โ
Frontend calls it on page load (lines 60-77 of [id]/page.tsx)
-โ Frontend API proxy was missing โ NOW CREATED!

-## Testing
-
-```bash
-# 1. Restart frontend (to load new route)

-# ๐ง Vote Check Endpoint - Issue & Fix
-
-**Date**: November 10, 2025
-**Issue**: `/api/votes/check` endpoint returning 404
-**Status**: โ
FIXED
-
----
-
-## The Problem
-
-You reported:
-```
-GET http://localhost:3000/api/votes/check?election_id=1
-Returns: 404 HTML page
-```
-
-**Why This Happened**:
-- The endpoint `/api/votes/check` didn't exist on the frontend
-- Next.js was trying to route it as a page instead of an API endpoint
-- Need to create the proxy route in frontend
-
----
-
-## The Solution
-
-### Created: `/frontend/app/api/votes/check/route.ts`
-
-This is a **Next.js API proxy route** that:
-1. Accepts GET requests with `election_id` query parameter
-2. Forwards them to the backend API
-3. Returns the vote check response
-
-```typescript
-GET /api/votes/check?election_id=1
- โ
-Frontend proxy (/frontend/app/api/votes/check/route.ts)
- โ
-Backend endpoint (GET /api/votes/check?election_id=1)
- โ
-Returns: { "has_voted": true/false, "election_id": 1, "voter_id": 123 }
-```
-
-### Backend Endpoint Already Exists
-
-File: `/backend/routes/votes.py` (line 766)
-
-```python
-@router.get("/check")
-async def check_voter_vote(
- election_id: int = Query(...),
- current_voter: Voter = Depends(get_current_voter),
- db: Session = Depends(get_db)
-):
- """Check if voter has already voted in this election"""
-
- vote_exists = db.query(models.Vote).filter(
- models.Vote.voter_id == current_voter.id,
- models.Vote.election_id == election_id
- ).first() is not None
-
- return {
- "has_voted": vote_exists,
- "election_id": election_id,
- "voter_id": current_voter.id
- }
-```
-
----
-
-## The Second Point You Mentioned
-
-> "Should ask at the beginning (load of the page), not at the submit button"
-
-**Status**: โ
ALREADY CORRECT
-
-The code is already checking on page load:
-
-```typescript
-// File: /frontend/app/dashboard/votes/active/[id]/page.tsx
-// Lines: 60-77
-
-useEffect(() => {
- const fetchElection = async () => {
- // ... fetch election details ...
-
- // โ
Check vote status when page loads
- try {
- const voteCheckResponse = await fetch(
- `/api/votes/check?election_id=${electionId}`,
- {
- headers: {
- Authorization: `Bearer ${token}`,
- },
- }
- )
-
- if (voteCheckResponse.ok) {
- const voteData = await voteCheckResponse.json()
- setHasVoted(!!voteData.has_voted) // โ
Set state on load
- }
- } catch (err) {
- // If endpoint doesn't exist, assume they haven't voted
- }
- }
-
- fetchElection()
-}, [voteId]) // โ
Runs on page load
-```
-
-This means:
-- โ
Vote status is checked immediately when page loads
-- โ
User sees "Vote Done" page right away if already voted
-- โ
User sees voting form if hasn't voted yet
-- โ
No waiting for submit button click
-
----
-
-## How It Works Now
-
-### User Flow: First Time Voting
-
-```
-1. User clicks: /dashboard/votes/active/1
- โ
-2. Page loads โ Component mounts
- โ
-3. fetchElection() runs in useEffect
- โ
-4. Check: GET /api/votes/check?election_id=1
- โ
-5. Response: { "has_voted": false }
- โ
-6. UI shows: Voting form โ
-```
-
-### User Flow: Already Voted
-
-```
-1. User visits: /dashboard/votes/active/1 again
- โ
-2. Page loads โ Component mounts
- โ
-3. fetchElection() runs in useEffect
- โ
-4. Check: GET /api/votes/check?election_id=1
- โ
-5. Response: { "has_voted": true }
- โ
-6. UI shows: "Vote Done" page directly โ
- (No voting form)
-```
-
----
-
-## Testing the Fix
-
-### Step 1: Restart Backend
-```bash
-docker compose restart backend
-sleep 3
-```
-
-### Step 2: Test the Endpoint
-```bash
-# Get your token from login first
-TOKEN="your_auth_token_here"
-
-# Test the endpoint
-curl -H "Authorization: Bearer $TOKEN" \
- "http://localhost:3000/api/votes/check?election_id=1"
-
-# Should return:
-# {
-# "has_voted": true/false,
-# "election_id": 1,
-# "voter_id": 123
-# }
-```
-
-### Step 3: Test in Browser
-1. Go to: `http://localhost:3000/dashboard/votes/active`
-2. Click on an election
-3. Check browser console (F12)
-4. Should see vote check happening on load
-5. If already voted โ See "Vote Done" page immediately
-6. If not voted โ See voting form
-
----
-
-## Files Changed
-
-### Created:
-- โ
`/frontend/app/api/votes/check/route.ts` (NEW proxy route)
-
-### Existing (No Changes):
-- โ
`/backend/routes/votes.py` (Already had endpoint)
-- โ
`/frontend/app/dashboard/votes/active/[id]/page.tsx` (Already called on load)
-
----
-
-## Before vs After
-
-### BEFORE โ
-```
-GET /api/votes/check?election_id=1
-โ 404 Not Found (HTML page)
-```
-
-### AFTER โ
-```
-GET /api/votes/check?election_id=1
-โ 200 OK { "has_voted": false, ... }
-```

-
----
-
-## Next Step
-
-1. Rebuild frontend:
- ```bash
- docker compose restart frontend
- sleep 3
- ```
-
-2. Test in browser:
- - Go to voting page
- - Should show vote status immediately on load
-
-3. Monitor console for any errors
-

-## Timing: Page Load vs Submit

-### Timeline
-
-```
-T=0ms โ User opens page
-T=100ms โ Component mounts
-T=110ms โ useEffect runs
-T=120ms โ GET /api/votes/check request sent โ
HERE (Page Load)
-T=200ms โ Response received
-T=210ms โ UI updated with vote status
-T=300ms โ Page fully rendered
-
-T=5000ms โ User clicks submit button
-T=5010ms โ Form validation
-T=5020ms โ POST /api/votes/submit โ
HERE (On Submit)
-T=5100ms โ Vote stored
-T=5110ms โ Success message shown
-```
-
-**Key**: Vote check happens at T=120ms (page load), NOT at T=5000ms (submit)

-## Request/Response Example
-
-### Request (from frontend to backend)
-```
-GET /api/votes/check?election_id=1 HTTP/1.1

-HTTP/1.1 200 OK
-Content-Type: application/json
-
-{
- "has_voted": false,
- "election_id": 1,
- "voter_id": 123
-}
-```
-
----
-
-## Error Cases
-
-### Case 1: User Not Authenticated
-```
-Request: No Authorization header
-Response: 401 Unauthorized
-Handler: Catch error, assume hasn't voted, show form
-```
-
-### Case 2: Invalid Election ID
-```
-Request: election_id=99999 (doesn't exist)
-Response: Voter found but election doesn't match - has_voted: false
-Handler: Show voting form
-```
-
-### Case 3: User Hasn't Voted Yet
-```
-Request: GET /api/votes/check?election_id=1
-Response: { "has_voted": false }
-Handler: Show voting form
-```
-
-### Case 4: User Already Voted
-```
-Request: GET /api/votes/check?election_id=1
-Response: { "has_voted": true }
-Handler: Show "Vote Done" page (no form)
-```

-# โก QUICK FIX - Vote Check Endpoint
-
-## What Was Missing
-The frontend API proxy route for `/api/votes/check` was missing.
-
-## What I Created
-โ
`/frontend/app/api/votes/check/route.ts`
-
-This route:
-- Accepts: `GET /api/votes/check?election_id=X`
-- Forwards to: Backend `GET /api/votes/check?election_id=X`
-- Returns: `{ "has_voted": true/false, ... }`
-
-## How It Works
-```
-Browser
- โ
-GET /api/votes/check?election_id=1
- โ
-Frontend Proxy (new route)
- โ
-Backend API
- โ
-Database query
- โ
-Response: { "has_voted": false }
- โ
-Frontend shows voting form OR vote done page
-```
-
-## Key Points
-- โ
Already called on page load (not just on submit)
-- โ
Backend endpoint already existed
-- โ
Frontend just needed the proxy route
-- โ
Works exactly as you wanted
-
-## Test It
-```bash
-# 1. Restart frontend
-docker compose restart frontend && sleep 3
-
-# 2. Visit voting page
-# http://localhost:3000/dashboard/votes/active/1
-
-# 3. Check console (F12)
-# Vote check should happen immediately on load
-```
-
-## Status
-โ
READY - Just restart frontend to apply the fix!

-```
-
-### Problem 2: Timing
-```
-"Should check at page load, not at submit button"

----
-
-## What I Fixed
-
-### โ
Created Frontend Proxy Route
-File: `/frontend/app/api/votes/check/route.ts`
-
-This route:
-- Listens to: `GET /api/votes/check?election_id=X`
-- Forwards to: Backend API
-- Returns: `{ "has_voted": true/false }`
-
-### โ
Confirmed Page Load Timing
-The frontend already calls this on page load (useEffect hook).
-No timing changes needed - it was already correct!
-
----
-
-## How It Works Now
-
-```
-User visits voting page
- โ
-Component mounts

-# Voting Setup Issue - Solution
-
-## Problem
-
-Users cannot vote because:
-1. Elections don't have ElGamal encryption keys (`elgamal_p`, `elgamal_g`)
-2. The voting interface fails when trying to get public keys
-
-## Root Cause
-
-The database initialization script `docker/create_active_election.sql` didn't set the ElGamal parameters, even though the init.sql had `elgamal_p = 23, elgamal_g = 5`.
-
-## Fix
-
-### Option 1: Fix via Database (Recommended)
-
-Connect to the database and update the elections with ElGamal parameters:
-
-```bash
-# Connect to MariaDB
-docker compose exec mariadb mariadb -u evoting_user -pevoting_pass123 evoting_db
-
-# Run this SQL:
-UPDATE elections SET elgamal_p = 23, elgamal_g = 5;
-
-# Verify:
-SELECT id, name, elgamal_p, elgamal_g FROM elections LIMIT 5;
-
-# Exit
-exit
-```
-
-### Option 2: Use Adminer UI
-
-1. Go to http://localhost:8081
-2. Login:
- - Server: `mariadb`
- - User: `evoting_user`
- - Password: `evoting_pass123`
- - Database: `evoting_db`
-3. Click on `elections` table
-4. Edit each row and set:
- - `elgamal_p` = 23
- - `elgamal_g` = 5
-
-### Option 3: Fresh Database Reset
-
-```bash
-# Stop and remove all data
-docker compose down -v
-
-# Start fresh
-docker compose -f docker-compose.multinode.yml up -d
-
-# Wait 40 seconds for initialization
-sleep 40
-
-# Verify elections have keys
-curl http://localhost:8000/api/elections/debug/all | jq '.elections[0] | {id, name, elgamal_p, elgamal_g}'
-```
-
-## Verify Fix Worked
-
-After fixing, test:
-
-```bash
-# Check election keys are set
-curl http://localhost:8000/api/elections/debug/all | jq '.elections[0] | {id, name, elgamal_p, elgamal_g}'
-
-# Should show:
-# {
-# "id": 1,
-# "name": "...",
-# "elgamal_p": 23,
-# "elgamal_g": 5
-# }
-
-# Get public keys (should work now)
-curl http://localhost:8000/api/votes/public-keys?election_id=1 | jq '.'
-```
-
-## Why This Happened
-
-The SQL scripts do this:
-1. `docker/init.sql` - Creates elections with `elgamal_p = 23, elgamal_g = 5`
-2. `docker/populate_past_elections.sql` - Inserts past elections (no ElGamal params)
-3. `docker/create_active_election.sql` - **Updates** election 1 but lost the ElGamal params
-
-The UPDATE statement in step 3 didn't preserve the ElGamal parameters. They should be:
-
-```sql
-UPDATE elections
-SET
- is_active = TRUE,
- start_date = DATE_SUB(NOW(), INTERVAL 1 HOUR),
- end_date = DATE_ADD(NOW(), INTERVAL 7 DAY),
- elgamal_p = 23,
- elgamal_g = 5
-WHERE id = 1;
-```
-
-## After Fix
-
-Once elections have ElGamal keys:
-
-1. Users can register normally
-2. Users can see active elections
-3. Frontend can fetch public keys for voting
-4. Encrypted voting works
-5. Blockchain records votes
-
-## Testing After Fix
-
-```bash
-# 1. Check keys are set
-curl http://localhost:8000/api/votes/public-keys?election_id=1
-
-# 2. Open frontend
-http://localhost:3000
-
-# 3. Register (if needed)
-# 4. Login
-# 5. Click "Participer" on an election
-# 6. Select a candidate
-# 7. Submit vote
-
-# Should see success message with transaction ID
-```
-
-## If Still Not Working
-
-1. Clear browser cache (Ctrl+Shift+Delete)
-2. Restart frontend container: `docker compose restart frontend`
-3. Rebuild frontend if config changed: `docker compose up -d --build frontend`
-4. Check backend logs: `docker compose logs backend | grep -i error`
-5. Check browser console for errors (F12)

-# Voting System Status Report
-
-## โ
Completed Tasks
-
-### 1. Frontend API Proxy Routes Created
-Successfully created a complete set of Next.js API routes to proxy all backend requests:
-
-**Elections endpoints:**
-- `/api/elections/route.ts` - GET (list elections)
-- `/api/elections/[id]/route.ts` - GET (specific election details)
-
-**Votes endpoints:**
-- `/api/votes/route.ts` - GET/POST (status, history, simple vote)
-- `/api/votes/submit/route.ts` - POST (submit encrypted vote)
-- `/api/votes/setup/route.ts` - POST (election setup)
-- `/api/votes/verify-blockchain/route.ts` - POST (blockchain verification)
-
-**Auth endpoints:**
-- `/api/auth/register/route.ts` - POST (register new user)
-- `/api/auth/login/route.ts` - POST (user login)
-- `/api/auth/profile/route.ts` - GET (user profile)
-
-### 2. Database Schema Fixed
-- SQL script `docker/create_active_election.sql` updated to preserve ElGamal keys
-- Elections now have `elgamal_p = 23, elgamal_g = 5` set
-
-### 3. Admin API Routes Created
-Created `/backend/routes/admin.py` with endpoints for:
-- `POST /api/admin/fix-elgamal-keys` - Fix missing ElGamal parameters
-- `GET /api/admin/elections/elgamal-status` - Check election crypto status
-- `POST /api/admin/init-election-keys` - Initialize public keys for voting
-
-## Current Architecture
-
-```
-Frontend (localhost:3000)
- โ
-Next.js API Routes (proxy layer)
- โ
-Backend (localhost:8000 via Nginx)
- โโโ Backend Node 1
- โโโ Backend Node 2
- โโโ Backend Node 3
- โ
-MariaDB (localhost:3306)
-```
-
-## What's Working
-
-โ
User registration and authentication
-โ
Election database with ElGamal parameters
-โ
Frontend can reach backend APIs via proxy routes
-โ
All three backend nodes operational
-โ
Blockchain recording elections (12 blocks verified)
-โ
Multi-node load balancing through Nginx
-
-## What Still Needs To Happen
-
-### 1. Backend Initialization of Election Public Keys
-Elections need their `public_key` field initialized for voting to work.
-
-Call the admin endpoint after backend restarts:
-```bash
-curl -X POST http://localhost:8000/api/admin/init-election-keys?election_id=1
-```
-
-### 2. Test Voting Workflow
-After backend is ready and keys are initialized:
-1. Register a user at http://localhost:3000
-2. Login
-3. Click "Participer" on an election
-4. Select a candidate
-5. Submit vote
-6. Verify vote appears in blockchain
-
-## Current Issue
-
-Backend is restarting after admin routes were added. This is normal and expected.
-
-The backend should restart automatically with the new admin endpoints available.
-
-Once it's ready, the system will be fully functional for voting.
-
-## Next Steps
-
-1. **Wait for backend to fully restart** (check `curl http://localhost:8000/`)
-2. **Initialize election keys** via admin endpoint
-3. **Test voting workflow** in the frontend
-4. **Verify blockchain integration** using blockchain endpoints
-
-## Database Query Status
-
-All elections now have:
-- โ
`elgamal_p = 23` (encryption prime)
-- โ
`elgamal_g = 5` (encryption generator)
-- โณ `public_key` - Being initialized (needs admin endpoint call)
-
-## API Endpoints Ready
-
-| Method | Endpoint | Status |
-|--------|----------|--------|
-| GET | `/api/elections/active` | โ
Working via proxy |
-| GET | `/api/elections/{id}` | โ
Working via proxy |
-| GET | `/api/votes/status` | โ
Proxy ready |
-| POST | `/api/votes/submit` | โ
Proxy ready |
-| POST | `/api/auth/register` | โ
Working (400 = email exists) |
-| POST | `/api/auth/login` | โ
Working |
-| POST | `/api/admin/fix-elgamal-keys` | โ
New endpoint |
-| POST | `/api/admin/init-election-keys` | โ
New endpoint |
-
-## Backend Logs During Last Run
-
-```
-โ Backend is receiving requests through Nginx
-โ All three backend nodes operational
-โ Database queries working correctly
-โ Auth endpoints returning proper responses
-```
-
-## File Changes Made
-
-1. **Frontend:**
- - Created 9 new proxy route files
-
-2. **Backend:**
- - Created `/backend/routes/admin.py` (new admin endpoints)
- - Updated `/backend/routes/__init__.py` (include admin router)
- - Fixed `/docker/create_active_election.sql` (preserve ElGamal params)
-
-3. **Configuration:**
- - `fix_elgamal_keys.py` (database update utility)
-
-## Expected Timeline
-
-- Backend restart: 1-2 minutes
-- Election key initialization: < 1 second per election
-- First test vote: < 2 seconds
-- Blockchain verification: < 1 second
-
-## Success Criteria
-
-โ
Frontend can reach backend (proxy routes)
-โ
Elections have ElGamal parameters (elgamal_p, elgamal_g)
-โณ Elections have public keys (public_key field)
-โณ User can submit encrypted vote
-โณ Vote appears in blockchain
-โณ Results can be verified
-
-## Testing Checklist
-
-After backend is ready:
-
-- [ ] Backend responding to `/api/` requests
-- [ ] Admin endpoint initializes election keys
-- [ ] Public keys show in election details
-- [ ] Frontend login works
-- [ ] Can view active elections
-- [ ] Can submit a vote
-- [ ] Vote recorded in blockchain
-- [ ] Blockchain verification succeeds
