Abstract
In this paper, we first obtain an algebraic formula for the moments of a centered Wishart matrix, and apply it to obtain new convergence results in the large dimension limit when both parameters of the distribution tend to infinity at different speeds. We use this result to investigate APPT (absolute positive partial transpose) quantum states. We show that the threshold for a bipartite random induced state on C d = C d 1 ⊗ C d 2 , obtained by partial tracing a random pure state on C d ⊗ C s , being APPT occurs if the environmental dimension s is of order s 0 = min (d 1 , d 2 ) 3 max (d 1 , d 2 ). That is, when s ≥ Cs 0 , such a random induced state is APPT with large probability, while such a random states is not APPT with large probability when s ≤ cs 0 . Besides, we compute effectively C and c and show that it is possible to replace them by the same sharp transition constant when min (d 1 , d 2 ) 2 ≪ d.

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
