Abstract
Abstract The Afro-Brazilians of West Africa refers to a community of people that was born in the 18th century and matured the 19th century in the course of trade exchanges between Brazil and West Africa. This is not a racial group but one united by a mixture of racial, commercial, cultural, and familial ties with a range of African, European, and American ancestries. The original foundation of the community emerged through the shipment of enslaved West Africans to Brazilian plantations. Upon liberation, many of these men and women, wanting to avoid a life of bondage and racial discrimination in the Americas, returned home to Africa. Others too old to leave Brazil or unwilling to abandon their American families and investments sent their Brazilian-born children back to Africa to see long-lost families and for business and education. There were also those descended from Brazilian traders who made Africa their home, sometimes marrying African wives, as well as their descendants and associates, free and unfree. Whether born in Africa or the Americas and regardless of color, the presence of Afro-Brazilians on both sides of the Atlantic necessitated intercontinental travels and exchanges and the birth of a transoceanic community. The history of Afro-Brazilians in West Africa has been a long and widely studied subject with a focus on its political and cultural contributions to the subregion.

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.
