-Enterprise Agentic Reliability Framework - Main Application (FIXED VERSION)
-Multi-Agent AI System for Production Reliability Monitoring
-
-CRITICAL FIXES APPLIED:
-- Removed event loop creation (uses Gradio native async)
-- Fixed FAISS thread safety with single-writer pattern
-- ProcessPoolExecutor for CPU-intensive encoding
-- Atomic saves with fsync
-- Dependency injection
-- Rate limiting
-- Comprehensive input validation
-- Circuit breakers for agent resilience
