Abstract
Solange Corbin was the first scholar to regard the lozenged punctum employed as mi-sign (“special punctum”) as the main characteristic of a “Portuguese notation” derived from Aquitanian notation. Even though Corbin’s findings were later partially revised, the special punctum is still regarded as a graphical feature mostly peculiar to Portuguese manuscripts. This palaeographical study investigates the use of the special punctum and the changes that occurred to Aquitanian notation in 104 fragments dated from the twelfth to the fifteenth centuries in the archives of Braga and Guimarães. This research demonstrates that the special punctum was the preferred scribal device employed to convey semitonal information, but that it was not systematically employed. Over the course of four centuries Portugal witnessed the coexistence of two parallel systems for notating plainchant. While both systems employed the typical elements of Aquitanian notation on a single line without clefs, one was perfectly diastematic while the other conveyed no indications of semitones.

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 it
