Abstract
Representative oligonucleotides (oligos), a 21-mer siRNA strand and a 16-mer ASO-like gapmer, were synthesized by Nanostar Sieving, a membrane-assisted liquid phase oligo synthesis (LPOS) method, at a 10 mmol scale and 20 mM concentration in a single solvent. This process is the first total LPOS beyond 10-mer, i.e., the reagents and intermediates remain in the liquid phase from the very first reaction to isolation. At all times during the synthesis of the full-length product, the concentration of oligos within the Nanostar-10 reactor remained roughly constant. Both sequences were synthesized four times, twice using membrane sheets clamped flat in circular cells and twice using scalable spiral wound modules. Cleavage and deprotection continued to maintain the oligo in the liquid phase until the final lyophilization, when yields were calculated from the optical density, adjusting for chromatographic and mass spectral purity. Synthetic process mass intensities approaching those of solid phase oligo synthesis (SPOS) were achieved.

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
