Abstract
Pathogen inactivation is expected to occur in compost if temperatures over 55°C (131°F) are maintained for at least 3 days, or 15 days in windrows. However, a literature review revealed pathogen survival in a significant number of processes appearing to meet the prescribed time-temperature criteria. It was hypothesized that pathogen survival may be due to the existence of undetected temperature variations within the compost mass. In order to investigate this possibility, it is necessary to monitor the conditions that a random particle of compost would experience as it passes through the composting process. As no adequate methods currently exist to monitor the temperatures of random particles, it was deemed necessary to develop a method to monitor temperature conditions that random particles of compost material encounter during the high-temperature phase of composting. A self-contained, battery powered temperature probe was designed for this purpose, with properties of size and density similar to those of compost particles, in order to allow it to move freely as it undergoes the composting process (in a manner similar to that of a random particle of material). Preliminary tests were done to ensure adequate device operation prior to manufacturing. Though the results were promising, improvements and further testing were recommended to ensure that the probe could withstand the harsh conditions encountered during composting, and to ensure that it would move randomly during compost agitation.

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
