 ## [Unreleased] - 2025-08-07
 
+### 🎉 **SAMO-DL Demo Website Integration - 100% COMPLETE** - 2025-01-15
+- ✅ **Fully Functional AI-Powered Demo Website**: Transformed static showcase into complete emotion analysis platform
+- ✅ **Real API Integration**: Connected to live SAMO DeBERTa v3 Large emotion detection API via CORS proxy
+- ✅ **Text Truncation System**: Implemented 400-character limit handling with user warnings and visual feedback
+- ✅ **Error Handling**: Robust validation for empty text, special characters, and network errors
+- ✅ **Custom Favicon**: Created and integrated bold 'S' favicon for professional appearance
+- ✅ **CORS Proxy**: Built `website/cors-proxy.py` to bypass browser security restrictions
+- ✅ **Security Headers**: Moved CSP from HTML meta tags to HTTP headers to eliminate violations
+- ✅ **User Experience**: Added loading states, success animations, and clear error messages
+- ✅ **API Testing**: Comprehensive testing with various text lengths and character types
+- ✅ **Production Ready**: All components tested and verified for deployment
+
+### Technical Achievements:
+- **Root Cause Resolution**: Fixed 500 Internal Server Error by implementing proper error forwarding in CORS proxy
+- **Text Processing**: Smart truncation system prevents API failures while maintaining user experience
+- **Real Model Output**: Displays actual emotion analysis results from SAMO DeBERTa v3 Large (27 emotions)
+- **Cross-Browser Compatibility**: Works across modern browsers with proper CORS handling
+- **Performance Optimized**: Fast loading with efficient API calls and minimal overhead
+
+### Files Created/Modified:
+- `website/favicon.ico` - Custom bold 'S' favicon
+- `website/comprehensive-demo.html` - Main demo page with favicon integration
+- `website/simple-test.html` - Test page with favicon
+- `website/index.html` - Homepage with favicon
+- `website/js/simple-demo-functions.js` - Core functionality with truncation logic
+- `website/cors-proxy.py` - CORS proxy with proper error handling
+- `website/http-server-with-csp.py` - HTTP server with security headers
+
+## [Unreleased] - 2025-08-07

 ### Added
 - HF emotion model integration as default local provider with env toggles (`EMOTION_LOCAL_ONLY` default on, `EMOTION_MODEL_DIR` default `${EMOTION_MODEL_DIR:-/models/emotion-english-distilroberta-base}` from centralized constants).
 - New endpoints in `deployment/secure_api_server.py`:

+# 🔒 Security Notice - Token Management
+
+## ⚠️ CRITICAL: JWT Token Handling
+
+**Date:** September 15, 2025
+**Issue:** Test reports contained actual JWT tokens from API testing
+
+### Actions Taken ✅
+
+1. **Sanitized test report:** `test_reports/comprehensive_api_test_1757950799.json`
+   - Replaced real JWT tokens with `[REDACTED_JWT_ACCESS_TOKEN]`
+   - Replaced refresh tokens with `[REDACTED_JWT_REFRESH_TOKEN]`
+
+2. **Updated documentation examples:**
+   - Replaced example JWT fragments with placeholder text
+   - Used generic `JWT_ACCESS_TOKEN_HERE` in all docs
+
+### Security Best Practices 🛡️
+
+#### For Test Scripts
+- **Never log actual JWT tokens** in test outputs
+- Use placeholder tokens in test reports
+- Sanitize sensitive data before saving results
+
+#### For Documentation
+- Use placeholder tokens like `JWT_ACCESS_TOKEN_HERE`
+- Never include real API keys, tokens, or secrets
+- Use `[REDACTED]` or `[PLACEHOLDER]` for sensitive fields
+
+#### For Development
+- Actual tokens are temporary (30min expiry) and test-only
+- Never commit `.env` files with real credentials
+- Use environment variables for production secrets
+
+### Token Security Context 🔍
+
+**The exposed tokens were:**
+- ✅ **Temporary test tokens** (30-minute expiry)
+- ✅ **Generated for testing purposes only**
+- ✅ **Not production credentials**
+- ✅ **Already expired**
+- ✅ **From test user account** (`test_user_*@example.com`)
+
+**Risk Assessment: LOW**
+- Tokens were short-lived test credentials
+- No production systems affected
+- No real user data exposed
+
+### Prevention Measures 🚨
+
+1. **Updated test scripts** to sanitize tokens before logging
+2. **Added security checks** to documentation process
+3. **Created this security notice** for future reference
+
+### Review Checklist ✅
+
+Before committing any files, ensure:
+- [ ] No real JWT tokens in any files
+- [ ] No API keys or secrets in clear text
+- [ ] Test reports use `[REDACTED]` for sensitive data
+- [ ] Documentation uses placeholder tokens only
+
+---
+
+**Security Status: RESOLVED** ✅
+**Future Risk: MITIGATED** 🛡️
