Abstract
We study a number of different ingredients related to $\ensuremath{\theta}$ dependence, the nondispersive contribution in topological susceptibility with the wrong sign, topological sectors in gauge theories, and related subjects using a simple ``deformed QCD.'' This model is a weakly coupled gauge theory, which however has all the relevant essential elements allowing us to study difficult and nontrivial questions which are known to be present in real strongly coupled QCD. Essentially, we want to test the ideas related to the $U(1{)}_{A}$ problem in a theoretically controllable manner using the ``deformed QCD'' as a toy model. One can explicitly see microscopically how the crucial elements work.

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
