Abstract
In kraft pulping process, plup is produced by cooking wood chips at high temperature with chemical liquors in a kraft pulp digester. The temperature uniformity inside the digester is difficult to determine precisely due to the digester size and complexity. This paper presents the design and calibration of a prototype flow-following sensor that measures and records temperature at regular time intervals inside a kraft pulp digester. To make a large-scale deployment economical, the sensor consists of mainstream automotive-grade electronic components. Experimental results show that the prototype can operate reliably at 175°C for 2 hours continuously and over 50 hours cumulatively. After calibration, the accuracy of the temperature measurement is better than ±0.51°C while the overall time accuracy is better than ±141s for a typical 8 hour long digester run.

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
