Abstract
Under weak restriction on the distortion measure the continuity of the. single letter distortion measure is established with respect to a suitable distance measure on the sequence space of elements drawn from the representation alphabet. This in turn translates into properties of the distortion rate function. Using subtleties about the behavior of the sequence distortion measure we develop a proof of convexity of the distortion rate function in full generality. A generalization of the optimality of Lempel Ziv algorithm with regard to finite state codes and stationary and ergodic sources with finite alphabet is presented for a more general class of universal codes applied to individual sequences.

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
