Abstract
This paper presents three maps that summarize current knowledge as to the extent of P ast permafrost and R elict permafrost in N orth A merica at approximately the time of the Last Glacial Maximum ( LGM ; c . 25–17 ka BP ) and during subsequent deglaciation until c . 10 ka BP . Analysis of the post‐1983 literature suggests that the extent of P ast permafrost south of the LGM limit was broader in eastern N orth A merica and slightly narrower in the I nterior G reat P lains than previously mapped. The recognition and dating of R elict permafrost in the nonglaciated terrain of the northwestern A rctic suggests that permafrost may be of great antiquity and can persist under changing climatic conditions. The formation of permafrost features during deglaciation suggests that ice‐proximal climatic conditions remained cold at least long enough for short‐lived permafrost aggradation; a latitudinal gradient is evident in the timing of its development as the L aurentide I ce S heet retreated.

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
