Abstract
The Clinton Administration argued for passage of the North American Free Trade Agreement (NAFTA), which was intended to dramatically reduce the number of migrants seeking to enter the United States. An expansion of the earlier Canada–US Free Trade Agreement of 1988, NAFTA eliminated tariff duties on products traded among the United States, Canada, and Mexico and provided for the gradual phasing out of other tariffs over a 15-year period. Latin America is home to half of the world's tropical forests and nearly half of the plant and animal diversity of the planet; thus the impact of climate change on the continent significantly affects the world at large. The tension between resource exploitation for profit and preservation of the natural environment in Latin America coincides with the arrival of the first European explorers. The United Nations and other international environmental groups have sought to strengthen financially and politically the work of homegrown activists.

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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
