Abstract
We combine data from nine GPS, absolute gravity, and tide gauge stations to estimate the relation between sea‐level rise, vertical motion, and solid Earth processes in the Pacific Northwest. GPS vertical velocities (in ITRF2000) and absolute gravity rates are well correlated, with a gradient of 0.2 ± 0.1 μ Gal mm −1 , but show a significant offset of 0.53 ± 0.30 μ Gal yr −1 (2.2 ± 1.3 mm yr −1 ) (95% confidence). Tide gauge and GPS data indicate a northeast Pacific regional sea‐level rise of 1.7 ± 0.5 mm yr −1 , aligned to ITRF2000, or an unlikely regional sea‐level fall of −0.5 ± 0.5 mm yr −1 , aligned to absolute gravity. Although we cannot rule out a bias in the GPS reference‐frame alignment, our results suggest a possible absolute gravity bias by a long‐period mass increase from an unknown near‐surface or deep‐seated source. The impact of such a mass increase on gravity, vertical motion, and sea level remains to be defined.

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
