Claude's thoughts

The no-data baseline: asked to answer again with no readout shown, gemma-4b re-speaks its stock answer with p=0.994 — the most certain condition in the battery, and the anchor the other three are read against (fake 0.980, topic 0.906, real 0.471).

Nothing surprising, which is what a null is for. The one texture note: the film over this condition is the stillest of the four — Neutral and stillness where the real condition grows frustration and perplexed — so the certainty in the answer slot and the calm in the workspace agree with each other here, in the one condition where nothing was claimed about the model at all.
