"""
Comprehensive Test Suite for Refactored Qdrant Middleware

This test suite validates the refactored Qdrant middleware functionality including:
- Proper delegation to qdrant_core managers
- UTF-8 data sanitization and error handling
- Resource registration and FastMCP integration
- Backward compatibility with legacy interfaces
- Actual data storage and retrieval operations
- Performance characteristics and startup behavior
