Datos y conjeturas sobre una carta náutica en pergamino de la desembocadura del río San Lorenzo (Canadá) conservada en la Real Academia de la Historia
Bibliographic record
Abstract
The navigation chart of the mouth of the Saint-Laurent river (Canada) was located in 1881 in the cover of a book of the Real Academia de la Historia. Surely it belonged to the Casa de Contratacion of Seville. From 1761 it was reused to bind a book of the Novitiate of San Luis of the Jesuits in Seville. For more than two hundred years it was hidden under the flyleaf. With the passage of time, the cover became lose and the letter was found. It was studied by Cesareo Fernandez Duro and published in chromolithography. In this investigation we presented some historical data that could be related to its origin and purpose. Charles V and the State and Indias Councils used espionage and diplomacy to know the intentions of Francis I in the expeditions to Canada. In 1541 they sent a caravel there to inform the emperor. Possibly, in order to illustrate the description of the voyage, the pilot made a drawing from the caravel, that later was copied in parchment for the Casa de Contratacion.

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.
