Abstract
We have developed plasmid vectors to enable selection of diploids from mating reactions between haploid strains that lack compatible recessive genetic markers. The plasmids bear one of five different dominant selectable markers, kanMX4, hphMX4, natMX4, patMX3 or ZEO, a yeast origin of replication, and the URA3 gene. Diploids can be selected from mating reactions between haploids transformed with plasmids expressing different dominant markers, by using a combination of drugs that select for both markers. Following non-selective growth, diploids that subsequently become cured of the plasmids can be directly selected on 5-FOA, for ura3 auxotrophs, or identified by replica-plating onto appropriate selective media.

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
