Abstract
Summary Milled wood lignins isolated from genetically modified poplar trees were studied by quantitative 31 P NMR spectroscopy, in combination with thioacidolysis and mild alkaline hydrolysis. The genetic transformation of the trees included down regulation of CAD and COMT enzyme activities. These analyses confirmed that moderate CAD down-regulation does not substantially alter lignin structure. In contrast, severe CAD deficiency alters the lignin structure more profoundly by decreasing the syringyl/guaiacyl ratio and increasing the degree of condensation of the lignin. The most severe alterations were observed in the lignins from the COMT-transformed lines.

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
