332 frozen holdout photos (test-holdout-ids-canonical.json, frozen 2026-08-25), live unified pipeline, same day 2026-09-29.
Each row: SAM3 off | SAM3 on | human ground truth. "err" = average line distance from the human line (% of image diagonal; a missed or extra stripe counts 5). Lower is better.
