Abstract
Abstract Ice lenses, soil layers, faults, sedimentary structures and gas bubbles in permafrost cores were imaged using a computed tomography scanner. Two kinds of images were produced: two‐dimensional sections which allow ice, gases and soil volumetric contents to be measured, and virtual three‐dimensional reconstructions of the entire core. Volumetric ice and gas contents were measured at 60% and 2% respectively. Ice and gas contents appear to be independent of each other along the stratigraphic profile. The shape and spatial distribution of gaseous inclusions in the permafrost provide some clues on gas source and on the thermo‐mechanics of ice segregation during permafrost aggradation.

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
