Abstract
The crystal structure of solifenacin hydrogen succinate [C 23 H 27 N 2 O 2 (HC 4 H 4 O 4 )] has been solved and refined using synchrotron X-ray powder diffraction data, and optimized using density functional techniques. Solifenacin hydrogen succinate crystallizes in space group P 2 1 (#4) with a = 6.477 03(2), b = 7.830 95(2), c = 23.848 72(7) Å, β = 90.2373(3)°, V = 1209.63(1) Å 3 , and Z = 2. The hydrogen succinate anions form a chain linked by strong hydrogen bonds parallel to the a -axis. Discrete N–H···O hydrogen bonds lie on the sides of this chain, resulting in a layer parallel to the ab -plane rich in hydrogen bonds. Halfway between these layers the molecules meet in a herringbone packing of aromatic rings. The powder pattern has been submitted to ICDD for inclusion in future releases of the Powder Diffraction File™.

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
