Abstract
Before the Civil War, free African Americans and fugitive slaves crossed international borders to places like Canada, Mexico, and the Caribbean in search of freedom and equality. Beacons of Liberty tells the story of how these bold migrants catalyzed contentious debates over citizenship, racial justice, and national character in the United States. Blending fresh historical analysis with incredible stories of escape and rebellion, Elena K. Abbott shows how the shifting geography of slavery and freedom beyond US borders helped shape the hopes and expectations of black radicals, white politicians, and fiery reformers engaged in the American anti-slavery movement. Featuring perspectives from activists and risk-takers like Mary Ann Shadd, Martin Delany, and James C. Brown, Beacons of Liberty illuminates the critical role that international free soil played in the long and arduous fight for emancipation and racial justice in the United States.

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.
