Issue of The Anti-Slavery Bugle featuring an article on the Fugitive Slave Law, October 12, 1850
Bibliographic record
Abstract
The Fugitive Slave Act of 1850 stipulated that refugees from enslavement living in the Northern States could be returned to slavery in the South if captured. This new act strengthened the Fugitive Slave Act of 1793 which gave slaveholders the right to capture escaped slaves, but did not require states to enforce it. Many Northern States simply ignored the act until the revised 1850 law, which made it illegal to assist escaped slaves in any way or obstruct their capture. The 1850 Act prompted thousands of slaves to flee to Canada. It has been estimated that between 1850 and 1860, 15,000 to 20,000 black people settled in Canada. Many used the Underground Railroad during their escape. The Act was repealed in 1864.

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.
