⚠️  CRITICAL ISSUES REMAINING
───────────────────────────────────────────────────────────────────────────

🔴 PRIORITY 1: Weak Database Password
   Current: "postgres" (common default)
   Action: Rotate to strong 32-char password
   Command: openssl rand -base64 32
   Impact: Critical security vulnerability

🔴 PRIORITY 1: Client-Side Authentication
   Current: Password hash in frontend source
   Action: Implement JWT + backend auth
   Impact: Easily bypassed by viewing source

🟡 PRIORITY 2: Monolithic Architecture
   Current: app.py (940 lines), App.js (7661 lines)
   Action: Refactor into modules
   Impact: Hard to maintain and test

🟡 PRIORITY 2: No Automated Testing
   Current: 0% test coverage
   Action: Add pytest + Jest tests
   Impact: Regression bugs

🚀 QUICK VERIFICATION

# Check service status
sudo systemctl status church-music-backend.service

# Verify rate limiting
curl -I http://localhost:8080/api/providers

# Expected response:
HTTP/1.1 200 OK
X-RateLimit-Limit: 60
X-RateLimit-Remaining: 59
X-Content-Type-Options: nosniff
X-Frame-Options: DENY
Strict-Transport-Security: max-age=31536000

# Test rate limit enforcement (should see 429 after 60 requests)
for i in {1..65}; do
  curl -s -o /dev/null -w "%{http_code}\n" http://localhost:8080/api/providers
  sleep 0.5

✨ IMMEDIATE ACTIONS REQUIRED
───────────────────────────────────────────────────────────────────────────

[ ] 1. Rotate database password (CRITICAL)
       openssl rand -base64 32
       Update .env and PostgreSQL user
       Restart backend service

[ ] 2. Set up automated backups
       crontab -e
       Add daily backup at 2 AM

[ ] 3. Monitor rate limiting
       Check backend/logs/app.log for "Rate limit exceeded"

[ ] 4. Plan JWT authentication implementation
       Design token structure
       Choose library (PyJWT)
       Define refresh token strategy
