Abstract
A new mechanism and sensors are described that can improve the quality of soil penetration resistance data. The electric-motor-driven mechanism pushes the cone into the soil at a constant rate. The force measurement is made with a miniature load cell sensor located adjacent to the cone head to reduce errors caused by friction between the soil and penetrometer shaft. A small water-content sensor is located on the shaft just above the load sensor, so that soil volumetric water content measurement is made on the hole walls just after the cone force is measured. The general nature of the electrical performance of the water content sensor was evaluated for different probe geometries by optimizing the portion of the electromagnetic energy passing into the soil compared to that remaining in the probe. Some early field and laboratory test results are shown, which were obtained using a complete prototype instrument. The resolution of each sensor is ±0.03 m 3 m −3 for water content, ±0.0007 MPa for cone penetration pressure (cone index) and ±0.003 m for depth. Key words: Water content, cone index, soil strength

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
