Abstract
Vitamin B1 (1) and its phosphate derivatives, thiamine monophosphate (2) and thiamine pyrophosphate (3), are shown to form stable 1:1 host-guest complexes with cucurbit[7]uril (CB[7]) in aqueous solution. The binding sites of CB[7] on these guests shift from the ethylthiazolium region of 1 to the pyrimidine moiety of 2 and 3 due to the presence of phosphate groups, leading to variations of binding affinities as well as C(2)-H/D exchange rate constants and C(2)-H pKa values with these guest molecules.

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
