Abstract
During a screening of a mini-Tn5-luxCDABE transposon mutant library of Pseudomonas aeruginosa PAO1 for alterations in swarming motility, 36 mutants were identified with Tn5 insertions in genes for the synthesis or function of flagellin and type IV pilus, in genes for the Xcp-related type II secretion system, and in regulatory, metabolic, chemosensory, and hypothetical genes with unknown functions. These mutants were differentially affected in swimming and twitching motility but in most cases had only a minor additional motility defect. Our data provide evidence that swarming is a more complex type of motility, since it is influenced by a large number of different genes in P. aeruginosa. Conversely, many of the swarming-negative mutants also showed an impairment in biofilm formation, indicating a strong relationship between these types of growth states.

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
