Bibliographic record
Abstract
Studio in parallelo di due pittori che contribuirono in maniera decisiva all'introduzione della maniera fiammingheggiante fra Liguria e Lombardia nel terzo quarto del Quattrocento, Jos Amman von Ravensburg, noto per un'Annunciazione firmata e datata 1451 in Santa Maria di Castello a Genova, di cui viene ricostruita una successiva attività milanese, e Zanetto Bugatto, pittore lombardo formatosi nella bottega di Rogier van der Weyden a Bruxelles fra 1461 e 1463, per cui viene argomentata l'identificazione col Maestro della Madonna Cagnola e rivendicato un ruolo di primo piano nella Lombardia sforzesca, a lato di Vincenzo Foppa e di Bonifacio Bembo. A parallel study of two painters who made a decisive contribution to the introduction of the Flemish manner between Liguria and Lombardy in the third quarter of the 15th century, Jos Amman von Ravensburg, known for an Annunciation signed and dated 1451 in Santa Maria di Castello in Genoa, whose later activity in Milan is reconstructed, and Zanetto Bugatto, a Lombard painter who trained in Rogier van der Weyden's workshop in Brussels between 1461 and 1463, for whom the identification with the Master of the Madonna Cagnola is argued and a leading role in Sforza Lombardy is claimed, alongside Vincenzo Foppa and Bonifacio Bembo.

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.
