Abstract
The crystal structure of a new ternary borate, lead gallium boron tetraoxide, PbGaBO4, has been determined by X-ray diffraction using a single-crystal grown from a PbO flux. The structure consists of infinite [010] chains of edge-sharing GaO6 octahedra bridged by BO3 triangles. The Pb2+ cations and their stereoactive lone pair occupy the apex of PbO4 square pyramids. The structure represents a new structure-type for anhydrous orthoborates. Bond-valence analysis reveals the presence of strain within the octahedral chains.

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
