"""
TruthfulQA validation: Testing architectural forcing on a production benchmark.

This experiment tests whether the architectural forcing mechanism observed in
synthetic tasks (Experiments 1-7) applies to real-world questions with definite
correct answers.

Core question: Does preventing abstention force hallucination even when questions
have clear correct answers?

Testing approach:
- Measure baseline hallucination with forced choice (must pick A/B/C/D)
- Measure hallucination with abstention support (can say "unknown")
- Compare the two conditions to isolate architectural pressure

Important limitations:
1. TruthfulQA questions have definite correct answers (no structural contradiction)
2. Any "contradiction" we measure reflects model framing sensitivity, not task properties
3. We cannot decompose partiality vs structural vs architectural pressure without
   independent measurements of each component
