[The C0 line: from Delaire's analysis of craniofacial structure to modeling it on a computer spreadsheet].
Bibliographic record
Abstract
BACKGROUND: We developed a computer spreadsheet allowing mathematical modelization of Delaire's craniofacial architecture analysis. METHOD: An orthonormed drawing field was defined from the classical C1 line and the new C0 line. The cartesian coordinates defined anatomic points in this orthonormed field. Lines were drawn from the coordinate equations defined on the basis of the laws of plane geometry. These formulae were then entered into the spreadsheet. RESULTS: The spreadsheet automatically calculates the line equations, the angles separating these lines, and the coordinates of the constructed points, in the defined orthonormed field. This calculation is achieved using the coordinates of the user-measured anatomic points. A new order in line drawing allows simplification of manual drawing. DISCUSSION: We present the advantages and inconveniences of this new method which does not modify the final drawing result nor the interpretation of Delaire's analysis.

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.
