Abstract
Yeasts of the artificial genus Candida include plant endophytes, insect symbionts, and opportunistic human pathogens. Phylogenies based on rRNA gene and actin sequences confirmed that the genus is not monophyletic, and the relationships among Candida species and allied teleomorph genera are not clearly resolved. Protein-coding genes have been useful to resolve taxonomic positions among a broad range of fungi. Over 70 taxa of the genus Candida and its allied sexually reproducing genera were therefore selected, and their phylogenetic relationships were investigated using nuclear sequences of the largest subunit and second largest subunit of RNA polymerase II gene, actin, the second subunit of the mitochondrial cytochrome oxidase gene, and D1/D2 LSU rRNA gene. The DNA sequences were analysed by maximum parsimony and Bayesian inference, resulting in the recognition of six major phylogenetic groups (A-F). Group A contains six facultative pathogenic Candida species, which seem to have derived from nonpathogenic species, while Group B contains species of Clavispora, Metschnikowia, and Pichia guilliermondii. Species of Debaryomyces form an independent group C that is related to groups A and B. Pichia fermentans and other environmental species are concentrated in Group D. Group E, containing Pichia anomala, may be a sibling to group F, which is represented by the Saccharomyces species complex.

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
