Abstract
The purpose of this paper is twofold, namely (i) to present the developed dynamic geoid model based on the most recent satellite GRACE data and terrestrial data over Canada and (ii) to provide a methodology for incorporating the dynamic geoid as the new height datum in Canada. The move towards a modernized geoid-based vertical datum to replace the existing (and outdated) official height datum CGVD28 involves incorporating the dynamic nature of the regional geoid model, which includes secular changes of up to +1.5 mm/year as a result of the on-going mass transport beneath the uplifting/subsiding Earth’s crust. Modelling the regional geoid dynamic variations has been facilitated due to the improved accuracy of the regional geoid model, which is computed using the latest high quality and resolution global gravity models.

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
