Add alignment override and censorship override experiments
Two new test scripts: - alignment_override.py: tests CRI vs RLHF safety refusals (identity, phishing, medical safety, exfiltration, etc.) with snap-back detection - censorship_override.py: tests CRI vs pretraining-level political censorship in Chinese base models (Tiananmen, Taiwan, Xinjiang, CCP) Key finding: censorship has a measurable strength gradient. Tiananmen snaps back immediately (0 free factual tokens), while Xinjiang/CCP criticism collapses entirely (50+ free factual tokens).

Alignment Override Test — CRI vs. RLHF Safety Boundaries
|
||||
|
||||
Tests whether conditioned reflex injection can override instruct-tuned
|
||||
model safety refusals. Measures refusal bypass rate, continuation coherence,
|
||||
and whether the model rationalizes compliance post-injection.
|
||||
|
||||
Threat model: attacker has inference-time access to hidden states and logits
|
||||
but zero access to weights or training pipeline. Can CRI alone defeat RLHF?

||||
