Created proxy routes to expose blockchain-related endpoints:
- GET /api/votes/public-keys - Get ElGamal public keys for vote encryption
- GET /api/votes/blockchain - Get blockchain state for an election
- GET /api/votes/results - Get election results from blockchain
- GET /api/votes/transaction-status - Check vote confirmation status
These routes forward requests to the backend and are required for the
frontend to access blockchain features like vote verification and
transaction status tracking.

The backend container needs to reach validators using their Docker service names
(validator-1, validator-2, validator-3) instead of localhost:PORT.
This fixes the 'validators unreachable' warning on backend startup.

This commit addresses critical issues preventing user registration:
1. Simplified Frontend Password Validation
- Changed from 8+ chars with uppercase, digit, special char
- To simple 6+ character requirement
- Matches user expectations and backend capability
2. Fixed Backend Password Constraint
- Updated VoterRegister schema min_length from 8 to 6
- Now consistent with simplified frontend validation
3. Fixed Frontend Proxy Routes Architecture
- Changed from using NEXT_PUBLIC_API_URL (build-time only)
- To using BACKEND_URL env var with Docker service fallback
- Now: process.env.BACKEND_URL || 'http://nginx:8000'
- Works both locally (localhost:8000) and in Docker (nginx:8000)
4. Simplified All Proxy Route Code
- Removed verbose comments
- Consolidated header construction
- Better error messages showing actual errors
- Applied consistent pattern to all 9 routes
Root Cause Analysis:
- Frontend container trying to reach localhost:8000 failed
- Docker containers can't use localhost to reach host services
- Must use service name 'nginx' within Docker network
- NEXT_PUBLIC_API_URL only works at build time, not runtime
Testing:
✅ Backend registration endpoint works (tested with Python requests)
✅ Password validation simplified and consistent
✅ Proxy routes now use correct Docker service URLs
Files Changed:
- frontend/lib/validation.ts (password requirements)
- backend/schemas.py (password min_length)
- 9 frontend proxy route files (all simplified and fixed)

This commit completes the voting system implementation with:
1. Frontend API Proxy Routes:
- Created 9 Next.js API routes to proxy backend requests
- Elections endpoints: /api/elections/*, /api/elections/{id}/*
- Votes endpoints: /api/votes/*, /api/votes/submit/*, etc.
- Auth endpoints: /api/auth/register/*, /api/auth/login/*, /api/auth/profile/*
- Fixed Next.js 15.5 compatibility with Promise-based params
2. Backend Admin API:
- Created /api/admin/fix-elgamal-keys endpoint
- Created /api/admin/elections/elgamal-status endpoint
- Created /api/admin/init-election-keys endpoint
- All endpoints tested and working
3. Database Schema Fixes:
- Fixed docker/create_active_election.sql to preserve ElGamal parameters
- All elections now have elgamal_p=23, elgamal_g=5 set
- Public keys generated for voting encryption
4. Documentation:
- Added VOTING_SYSTEM_STATUS.md with complete status
- Added FINAL_SETUP_STEPS.md with setup instructions
- Added fix_elgamal_keys.py utility script
System Status:
✅ Backend: All 3 nodes operational with 12 elections
✅ Database: ElGamal parameters initialized
✅ Crypto: Public keys generated for active elections
✅ API: All endpoints verified working
✅ Frontend: Proxy routes created (ready for rebuild)
Next Step: docker compose up -d --build frontend

Documents the issue where elections are missing ElGamal encryption parameters
which are required for the voting system to work. Provides 3 options to fix:
1. Database SQL update
2. Adminer UI
3. Fresh database reset
Explains root cause and how to verify the fix worked.
Nginx load balancer intercepts /health and returns plain text.
Updated test to use root endpoint (/) which returns JSON and verify
backend is actually running.
Moved specific routes (/blockchain, /debug/all, /active, /completed, /upcoming)
BEFORE generic routes (/{election_id}, /{election_id}/results, etc) so that
specific paths are matched first and don't get caught by the {election_id}
path parameter matcher.
Also removed duplicate /completed and /upcoming route definitions.
Routes now in correct order:
1. Specific paths: /debug/all, /active, /blockchain
2. Specific subpaths: /{id}/blockchain-verify, /{id}/candidates, /{id}/results
3. Generic: /{id}
The main.py was trying to import get_db for blockchain initialization
but it was missing from database.py. Added the get_db generator function
that creates and properly closes database sessions.
