Abstract
The intepretation of sea-level indicators (SLIs) in terms of glacial-isostatic adjustment (GIA) has usually been based on neighbouring SLIs grouped into a single sea-level curve, which is then assumed to represent the Holocene sea-level change in that region. In this method, the nominal height and age of a particular SLI are the only characteristics considered in the inference of the former sea-level height. However, only isolation basins yield a narrow range for sea level, whereas SLIs based on samples, such as flotsam, shells or peat, only allow the determination of an upper or lower bound or a range for it. To use also these types of sample properly, we have developed a classification scheme based on Fuzzy logic. After the defintion of appropriate membership functions, this method leads to a more systematic and realistic interpretation of the large amount of SLIs available. We apply this method to SLIs from several regions in Canada and demonstrate how it modifies the inference of GIA for a particular region and, thus, the determination of mantle viscosity.

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
