Swiss Cheese Validation: Verify Critic Independence

Purpose

Verify that multiple critic layers have orthogonal failure modes, ensuring the Swiss cheese model is working correctly. Measure overlap in critic rejections and warn if critics catch the same errors.

Theory

The Swiss cheese model achieves reliability through misaligned holes:

• Each critic has failure modes (errors it misses)
• Holes don't align across critics
• Errors caught by different critics don't overlap significantly

Target: Independence score > 0.85 (less than 15% overlap)
