Abstract
Clinometaborite, β-HBO 2 , the monoclinic modification of metaboric acid, which has long been known as a synthetic product only, was found as a sublimate in an active medium-temperature intracrater fumarole at La Fossa crater, Vulcano Island, Aeolian archipelago, Sicily, Italy. It forms aggregates of stout crystals up to 2 mm long in an altered pyroclastic breccia, associated with metaborite, sassolite and adranosite. The unaltered mineral is colorless and translucent, with a vitreous luster; it becomes chalky white after some months of exposure to open air. The crystal habit is prismatic; twinning was not observed. The strongest six lines in the X-ray powder-diffraction pattern [ d obs in A( I ) hkl ] are: 3.078(100)201, 4.193(20)111, 6.773(15)001, 2.550(10)122, 3.224(8)201, and 2.702(8)031. The unit cell is monoclinic, space group P 2 1 / a , with a 7.127(2), b 8.842(3), c 6.773(2) A, β 93.21(1)°, V 426.1(2) A 3 , Z = 12, values that virtually coincide with those of the synthetic compound. The calculated density is 2.049 g/cm 3 . The structure was refined to a final R of 0.043 for 977 observed reflections [ I > 2σ( I )]. Both the mineral and the mineral name have been approved by the IMA Commission on New Minerals, Nomenclature and Classification (IMA 2010–022).

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
