Abstract
A comprehensive test ban treaty, or CTBT, is the oldest item on the nuclear arms control agenda.Three treaties currently limit testing to underground only, with a maximum force equal to 150,000 tons of TNT.According to the Natural Resources Defense Council, the United States conducted 1,030 nuclear tests, the Soviet Union 715, the United Kingdom 45, France 210, and China 45.The last U.S. test was held in 1992; the last U.K. test, in 1991.Russia claims it has not conducted nuclear tests since 1991.Since 1997, the United States has held 21 "subcritical experiments" at the Nevada Test Site, most recently on May 25, 2004, to study how plutonium behaves under pressures generated by explosives.It asserts these experiments do not violate the CTBT because they cannot produce a self-sustaining chain reaction.Russia has reportedly held some since 1998, including several in 2000.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
