Abstract
Two new occurrences of anduoite, (Ru,Os)As2, a rare platinum-group mineral (PGM), are reported from chromitites, one from the Kapitanov deposit, Ukrainian Shield, Ukraine, and the other from the Maja e Sukes deposit, Tropoja ophiolitic massif, Albania. At Kapitanov, anduoite occurs as discrete, homogeneous, euhedral crystals (6–9 and 1–2 � m) enclosed in two chromian spinel grains devoid of fractures. At Maja e Sukes, one crystal of anduoite (3 � m in diameter) belongs to a complex polyphase assemblage of PGM comprising sperrylite, hollingworthite and an unnamed sulfarsenide of Rh, Ir, Pd and Ni. The chemical composition of anduoite is comparable in both deposits: (Ru 0.79–0.80Os0.10–0.11Ir0–0.03Rh0.03–0.04Pt0–0.01Pd0.01–0.02Ni0–0.04)� 0.98– 1.01(As1.98–2.01S0.01–0.02)� 1.99–2.03. These examples of anduoite have a lower content of Ru than that described from the type locality in Tibet. A magmatic origin is proposed.

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
