Abstract
In this paper, we study batch codes, which wereintroduced by Ishai, Kushilevitz, Ostrovsky and Sahai in [4].A batch code specifies a method to distribute adatabase of $n$ items among $m$ devices (servers)in such a way that any $k$ itemscan be retrieved by reading at most $t$ items from each of the servers. It is of interest to devise batch codes thatminimize the total storage, denoted by $N$, over all $m$ servers.We restrict out attention to batch codesin which every server stores a subset ofthe items. This is purely a combinatorial problem, sowe call this kind of batch code a ''combinatorial batch code''.We only study the special case $t=1$, where,for various parameter situations, we are able to presentbatch codes that are optimal with respect to the storagerequirement, $N$. We also study uniform codes, where every item isstored in precisely $c$ of the $m$ servers (such a codeis said to have rate $1/c$). Interesting new resultsare presented in the cases $c = 2, k-2$ and $k-1$. In addition,we obtain improved existence results for arbitraryfixed $c$ using the probabilistic method.

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
