Abstract
Significance Correlated electron systems often show unexpected behavior that defies theoretical explanations. One such mystery is the universal presence of V-shaped gaps with surprisingly linear energy dependence, whose origins are as-yet unknown. Conventional wisdom implicates static order like charge density waves or fluctuations of a nearby order parameter like superconductivity or antiferromagnetism. However, adding dopants to correlated systems inevitably leads to the opposite of order—i.e., electronic disorder—which begs the question: Could disorder create well-defined signatures in electronic properties? By carefully choosing a material with no additional order, we show that order is not the only path to gaps and that disorder may play a surprising role in generating universal signatures in the density of states of disordered correlated systems.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
