Abstract
The EXO-200 experiment is searching for neutrinoless double beta decay using a time projection chamber filled with liquid xenon enriched in Xe-136. The detector has demonstrated exceptional performance with world leading measurements and stringent search results. The detector finished its Phase-I running shortly after an unexpected interruption in operations caused by incidents at the Waste Isolation Pilot Plant, but has restarted in Phase-II with hardware upgrades. During the two-year hiatus, the EXO-200 collaboration published several results using data from Phase-I. This article reports on the recent results and status of this detector, as well as on the proposed nEXO detector, the next generation experiment rooted in the success of EXO-200.

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
