Abstract
Abstract This paper documents a method to determine the degree of saturation, Sr, of a soil specimen at any time during a rigid-wall permeameter test. This method first indicates that the tested specimen usually is not fully saturated. Then it is used to prove that the usual test termination criterion based on equality of inflow and outflow volumes may be misleading. Examples are provided where the two volumes were equal within 1 %, whereas Sr increased from 80 to 100 % and k increased by a factor of 4. Without knowing the technique to determine the Sr value at any time, the test would have been stopped prematurely and would have given some k(Sr) value for an unknown Sr with the risk of misinterpreting this result as k(Sr = 100 %). New equations for gas transfer between water and gas bubbles are also established and experimentally verified for specimens permeated with either deaired water or water over-saturated with air.

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
