Abstract
(1R,3S)-Camphoric acid [(1R,3S)-1,2,2,-trimethylcyclopentane-1,3-dicarboxylic acid, C(10)H(16)O(4)] forms adducts with a range of amines in which the acid component may be the neutral molecule, the mono-anion (C(10)H(15)O(4))(-) or the di-anion (C(10)H(14)O(4))(2-). The structures generated by the hard hydrogen bonds take the form of chains in the 1:1 adducts (II) and (III) formed with 4,4'-bipyridyl and 1,2-bis(4-pyridyl)ethane. There are single sheets in the hydrated 1:1 adduct (IV) formed with 1,4-diazabicyclo[2.2.2]octane, and pairwise-interwoven sheets in the 2:1 adduct (V) formed with hexamethylenetetramine. Three-dimensional frameworks are present in the salt-like 1:1 adduct (VI) formed with piperazine and in the hydrated 3:1 adduct (VII) formed with N,N'-dimethylpiperazine. This latter adduct contains both neutral C(10)H(16)O(4) and anionic (C(10)H(15)O(4))(-) units. In (II), (III) and (IV), the chain and sheet substructures are linked by C-H...O hydrogen bonds to form three-dimensional frameworks. The monoclinic polymorph of camphoric acid itself (I) has been reinvestigated.

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
