Abstract
Abstract We fed adult Caenorhabditis elegans fluorescent microspheres mixed with their Escherichia coli food and then measured the total fluorescence of expelled faeces as a function of time after transfer to unlabelled bacteria. Intestinal clearance obeys a simple first-order decay or dilution curve: we estimate that 43 ± 10% of the maximum intestinal volume is expelled in each defecation and the average residence time of a bead (by inference, a bacterium) is less than 2 min. Our results raise questions how bacteria can be sufficiently digested in this brief period to provide energy and material to sustain the high rate of C. elegans oocyte production.

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
