Abstract
It has been claimed that measurements of trapped magnetic flux in hydrides under pressure provide evidence for superconductivity in these materials (Minkov et al., 2022; Minkov et al., 2023). In recent work we have questioned that claim (Hirsch and Marsiglio, 2022). Here we point out that recent experiments (Bud’ko et al., 2023) provide further evidence supporting our questioning of that claim. We also present calculations for a thin disk and compare these with those previously calculated for a long cylinder. The results are qualitatively similar, and therefore reinforce our previous conclusions. We also address recent criticism of our paper Ref. (Hirsch and Marsiglio, 2022) by Bud’ko (2024) and by Talantsev et al. (2023).

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
