 - **Metrics.** Accuracy, AUC and F1 treat each pixel as a binary decision; Dice and
   mIoU measure region overlap. Pixel-level accuracy/AUC are dominated by the large
   untouched background, so Dice/mIoU are the more informative scores.
-- **Robustness.** Evaluation can additionally be performed under JPEG compression
-  (quality 0.75) and Gaussian blurring (sigma = 1.0).

-## Known issues
-
-- For 12 samples in Qwen-Image-Edit, the source metadata omitted `img_name` and
-  `edit_type`. These fields were recovered from the filename (all 12 are
-  `addition` samples); no other field is affected.
-- `boxes` / `scores` are detector/segmenter outputs and can include coordinates
-  slightly outside the image, or several boxes for one instruction.
