The audit evaluates linear deception probes across four instruction-tuned language models using controlled, task-defined deceptive decisions.","At each transformer block, we compare a probe-weight steering direction with a contrastive direction built from honest-minus-deceptive activations. Intervention layers and strengths are selected on held-out validation scenarios and evaluated on untouched test groups under explicit limits on capability loss.","Selection regret measures useful intervention benefit forgone when a probe-guided selection misses a better feasible intervention. Accurate detection and effective intervention require separate evidence: predictive performance does not consistently identify useful steering directions or layers.","I led the experimental design, implementation, and empirical evaluation, built the main research workflow, ran most experiments, and coordinated the analysis.
