Abstract
On April 8, 1999, 50 litres of a dense non‐aqueous phase liquid were released into a natural groundwater flow field at Canadian Force Base Borden. It was expected that this contaminant would migrate downward forming a series of immiscible phase pools. Further, it was anticipated that the mass of these pools would be reduced over time by dissolution and advection of the dissolved phase of chlorinated solvent due to the groundwater flow field. Ground penetration radar profiling with 200 MHz antennas was conducted before and after the release until the Fall 2004 to detect the location of the immiscible solvent pools and monitor their evolution with time. Changes in reflectivity were used to infer the presence and evolution of the contaminant pools. These changes were determined from signal amplitude and complex trace attribute variations between the background and post‐release profiles. While results of these two techniques differ in some details, they provided overall mutually consistent information about the state of the pools. Early data clearly shows the development of two laterally extensive pools at different depths. These pools subsequently reduced in both size and reflectivity and almost completely disappeared by the end of the GPR monitoring period.

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
