Abstract
Fischesserite, Ag3AuSe2, from the De Lamar mine, Owyhee County, Idaho, USA, was chemically and structurally analyzed. Electron-microprobe analyses give the chemical formula Ag2.98Cu0.01Au0.97Se2.03. Fischesserite is optically isotropic, silver white in color with a metallic luster. In reflected light, the mineral is pink. Where observed near naumannite, it appears darker with slightly bluish tints. Reflectivity values are 32.5 (471.1 nm), 30.0 (548.3 nm), 31.1 (586.6 nm), and 33.7% (652.3 nm). Fischesserite is cubic, space group I 4132, with a 9.965(1) A, V 989.5(2) A3 and Z = 8. The crystal structure has been refined to R = 2.69%. Fischesserite exhibits a garnet-like structure consisting of edge-sharing Ag[Se4Ag2Au2] and Au[Ag6Se2] polyhedra. Fischesserite is confirmed to be isotypic with petzite, Ag3AuTe2. The different crystal-chemical environments of noble metals in fischesserite and petzite are compared with those found in other silver–gold chalcogenides.

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
