    Subspace Dictionaries Across Depth: Comparing SASA and Sparse Autoencoders in Gemma 3 1BSASA dictionaries at all 26 layers of Gemma 3 1B, against Gemma Scope 2 SAEs and random-subspace controls. Projected group-norms predict semantic entropy well above the controls; the apparent split by cause (ambiguity, knowledge gaps, missing information, computational difficulty) turns out to be a dataset-identity confound: AUROC 1.000 falls to 0.453 under a passage-matched control.
