Abstract
Abstract The basal temperature of snow (BTS) method was used to predict the distribution of permafrost within a mountainous basin located in the southern Yukon Territory. A modelled BTS surface, based on several hundred measured values, was created within a Geographic Information System (GIS) environment using elevation and potential incoming solar radiation as independent variables. The distribution of frozen ground at 200 test sites was compared to the modelled BTS values using logistic regression. The resultant map of permafrost probability shows that all four conventional permafrost distribution classes (isolated patches, scattered and widespread discontinuous permafrost, and continuous permafrost) are present within the basin. Supplementary logistic regression analyses reveal that at certain elevations and aspects, the probability of permafrost occurrence varies markedly over short distances in response to snowpack depth. They also show that widespread alterations in snow cover would be expected to substantially affect permafrost distribution even if air temperatures were to remain unchanged.

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
