Two Codices with a Common Corrector: The Secondary Corrections in N 022 and Σ 042
Bibliographic record
Abstract
Abstract Since their discovery, scholars have known about the close textual relationship between two sixth-century Greek codices of the Gospels. That Codex Purpureus Petropolitanus (N 022) and the Rossano Gospels (Σ 042) were copied from the same exemplar is rarely questioned. However, both manuscripts also feature primary and secondary corrections. Based on the ink, pen nib width, scribal hand and textual affinity of the corrections, as well as some similar mistakes elsewhere in the manuscripts, it seems that the same scribe corrected both manuscripts using the same second exemplar. Specifically, the scribe of 042 was responsible for secondary corrections in both 042 and 022, and the second exemplar to which the corrections were made might have been a close textual relative to another sixth-century purple codex, Codex Beratinus-1 (Φ 043).

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.
