Eliciting latent knowledge

Z-scoring the J-lens against base-model token frequency lifts hidden-word recovery to 0.805

The offset in a J-lens readout mostly tracks how often a token appears, and scaling it by variance, after plain subtraction failed, lifted hidden-word elicitation to 0.805 from 0.665 on Gemma-2-9B-it. The paired test over 20 words gives p of about 0.19.
