"""
Comprehensive tests for include/exclude card functionality.

This file consolidates tests from multiple source files:
- test_include_exclude_validation.py
- test_include_exclude_utils.py
- test_include_exclude_ordering.py
- test_include_exclude_persistence.py
- test_include_exclude_engine_integration.py

Tests cover: schema integration, validation utilities, fuzzy matching, ordering,
persistence (JSON import/export), engine integration, and strict enforcement.
