Abstract
OBJECTIVES: To evaluate the intrarater and inter-rater reliability of the Sunnybrook Facial Grading System (SFGS) by novice users. DESIGN: Prospective interval study using one measurement instrument. SETTING: Tertiary teaching hospital (Sunnybrook & Women's College Health Science Centre). METHODS: Twenty-two patients with a wide spectrum of facial dysfunction recorded on videotapes were rated using the SFGS by eight novice observers independently in two different sittings separated by 3 weeks. The order of patients was randomized for the second sitting. Intraclass correlation coefficients were calculated for component scores and for total scores within and between raters. RESULTS: The intrarater reliability coefficients for the eight raters ranged from .838 to .929. This largely overlaps with the data obtained in previous studies with expert raters. The inter-rater reliability for all eight raters at time 1 was .982 and for time 2 was .970. This is higher than what was previously obtained with expert raters. CONCLUSION: The SFGS is as reliable when applied by novice users as by expert users.

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
