Abstract
On February 8, 1785, the Gazeta de México , one of New Spain's first news periodicals, published an announcement from the city of Guanajuato celebrating the recent birth of a pair of conjoined twins: Doña Rafaela Cortés … has delivered two children from one birth, joined together at the back of their heads by the skull. They received the holy waters of baptism and were christened Joseph Nepomuceno Guadalupe and Joseph Ignacio Guadalupe… Many people, admiring these rare effects of nature, have visited them, and there has been no record in these twins of any deformity or defect in their separate and agile bodies… The few doctors and surgeons residing in the city have considered separating them, but have not found it advisable because of the manner in which they are united, and every day more news circulates about their existence and longevity, causing ever more admiration for them given that the first one was born foot-first, and in delivering him, the midwife discovered the knot that joined the two heads.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
