Abstract
High-pressure in situ powder-diffraction data were collected on a sample of P4/n vesuvianite from Val d’Ala, Piemonte, Italy, between room pressure and 13.2 GPa. No deviation from tetragonal symmetry was found at any pressure. The refined unit-cell parameters show that the highest compressibility is along the c axis [a = 2.00(4)•10–3 GPa–1 and c = 2.42(7)•10–3 GPa–1]. Such behavior, which is inverse to that observed with increasing temperature, is related to weaker bonding along the 4-fold axis owing to the presence of hydrogen bonding and vacancies. A third-order Birch–Murnaghan equation of state was fitted to the retrieved volumes, with V0 = 2859.47(7), KT0 = 125.5(1.3) GPa and K’T0 = 4.8(3). The compressibility of P4/n vesuvianite probably applies to all members of the vesuvianite family.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
