Pennsylvania: An Act for the Gradual Abolition of Slavery
Bibliographic record
Abstract
On March 1, 1780, with the Revolution still raging and its outcome in doubt, the Pennsylvania legislature became the first legislature in history to take steps to abolish slavery. Pennsylvania’s Act for the Gradual Abolition of Slavery is both idealistic and practical. It tries to balance the idea of liberty, which was at the heart of the Revolution, with the founding generation’s deep respect for private property. The law also recognizes the significance of race in both the creation of slavery and the perpetuation of discrimination against former slaves. Eventually four other states and a Canadian province—Connecticut (1784), Rhode Island (1784), New York (1799), New Jersey (1804), and Upper Canada (present-day Ontario) (1794)—adopted similar laws to end slavery. Thus the Pennsylvania law became a model for how places with slavery ended the institution. These places accomplished what no other societies before them had: the peaceful eradication of slavery.

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.
