🎯 S3 END-TO-END TESTING MILESTONE: All 13 Tests Passing!

✅ COMPLETE S3 JWT AUTHENTICATION SYSTEM:
- JWT Bearer token authentication
- Role-based access control (read-only vs admin)
- IP-based conditional policies
- Request context extraction
- Token validation & error handling
- Production-ready S3 IAM integration

🚀 Ready for next S3 features: Bucket Policies, Presigned URLs, Multipart
