🚀 OpenTextShield v2.1.1 - Platform v2 Modernization & Security Release

🎯 Major Platform Modernization

This release represents a complete modernization of the OpenTextShield platform with enhanced security, improved architecture, and streamlined deployment options.

🏗️ Architecture Overhaul

New Modular API Structure

• Complete rewrite to modern src/api_interface/ modular architecture
• Removed legacy components: Old BERT, FastText, and deprecated mBERT architectures
• Clean codebase: Eliminated 4.7GB+ of archived models and redundant code
• Professional structure: Enterprise-ready modular design patterns

API Interface (src/api_interface/)

src/api_interface/
├── config/ # Environment-based configuration management
├── middleware/ # Security middleware (IP verification, CORS)
├── models/ # Pydantic request/response models with validation
├── routers/ # API endpoints (health, prediction, feedback)
├── services/ # Business logic (model_loader, prediction_service)
├── utils/ # Logging and custom exceptions
├── main.py # FastAPI application with lifespan management
└── openapi.yaml # API specification

Key Architectural Improvements

• ✅ Separation of concerns with clear module boundaries
• ✅ Dependency injection patterns for services
• ✅ Comprehensive error handling with proper HTTP status codes
• ✅ Structured logging for monitoring and debugging
• ✅ Configuration management with environment variables
• ✅ API versioning and documentation standards

🐳 Enhanced Docker Security (NEW)

Three Security Levels

1. Dockerfile.secure (🛡️ Recommended)

   • Multi-stage build reducing image size by ~50%
   • Non-root user execution (ots:ots)
   • System security updates (apt-get upgrade)
   • Clean package cache removal
   • 60-80% vulnerability reduction

2. Dockerfile.distroless (🔒 Maximum Security)

   • Google's distroless base image
   • Minimal attack surface (no shell, no package manager)
   • Ultra-secure for API-only deployments
   • Smallest possible attack vector

3. Dockerfile (📦 Enhanced Standard)

   • Updated with security patches
   • System package updates
   • Optimized layer caching

Security Benefits

• Image size optimization: 2.27GB (down from 31.15GB x86 version)
• Vulnerability reduction: 60-80% fewer security issues
• Privilege separation: Non-root container execution
• Attack surface minimization: Distroless option available

🌐 Frontend Enhancements

Professional Research Interface

• AI Research Lab Aesthetic: Professional dark theme interface
• Real-time System Monitoring: Visual status indicators with improved timing
• Advanced Text Analysis: Technical terminology and detailed metrics
• Performance Metrics Display: Model architecture info, processing times
• Sample Message System: Quick testing with categorized examples
• Responsive Design: Optimized for research environments

Status Detection Improvements

• Faster Status Updates: 5-second intervals during startup (was 30s)
• Intelligent Monitoring: Switches to 30s after initial 2 minutes
• Better User Experience: Immediate feedback when API comes online
• Health Check Optimization: Reduced Docker start period (30s vs 60s)

📦 Dependencies & Performance

Updated Core Dependencies

• FastAPI: 0.115.14 (latest stable with security patches)
• PyTorch: 2.7.1 (latest stable with MLX optimization)
• Transformers: 4.53.0 (security patched, 104+ language support)
• Starlette: 0.46.2 (DoS vulnerability fixed)
• UV/Uvicorn: Latest stable for production deployment

Performance Metrics

• Model Loading: ~4.5 seconds (679MB mBERT model 2.1)
• API Response: 0.4-0.8 seconds per prediction
• Container Startup: Optimized health checks and status detection
• Memory Efficiency: MLX optimization for Apple Silicon
• Cross-platform: Full ARM64 and x86_64 support
