| Check | Failure that thumbnails hide |
|---|---|
| Identity | Eye spacing, jaw, hairline, and age shift between scenes |
| Skin and light | Waxy texture, contradictory catchlights, or beauty-ad smoothing in a supposedly candid shot |
| Physical logic | Hands that do not hold objects, impossible reflections, floating jewelry, or background furniture that merges |
| Production cost | Blocked attempts, rerolls, face repair, inpainting, and manual retouching before one image is usable |
