Comprehensive chaos engineering system for validating clean architecture layer independence:

- 7-layer architectural dependency matrix with transitive dependencies
- Multiple chaos injection strategies (import_failure, module_unavailable, function_failure)
- Automated dependency violation detection and reporting
- Safe chaos injection with state restoration mechanisms
- Integrated Makefile targets for chaos testing workflow
- Comprehensive logging and result persistence
- JSON report generation with architectural insights

Makefile additions:
- chaos-validate: Full architectural independence validation
- chaos-matrix: Display dependency matrix
- chaos-inject: Targeted layer chaos injection
- chaos-report: Generate comprehensive analysis reports

The system systematically injects controlled failures and monitors impact across
architectural layers to ensure proper isolation and dependency management.

"""
Architectural Layer Independence Test Runner with Chaos Engineering
This module implements a sophisticated chaos engineering system that validates
architectural layer independence by injecting controlled failures and monitoring
the impact on dependent and independent layers.
The system systematically tests that:
1. Failures in lower layers propagate only to dependent upper layers
2. Independent layers remain unaffected by failures in unrelated layers
3. The dependency matrix matches the intended architectural design
Usage:
python chaos_test_runner.py [options]
Commands:
validate-independence Run full architectural independence validation
inject-layer-failure Inject failure into specific layer
dependency-matrix Show architectural dependency matrix
chaos-report Generate comprehensive chaos test report
