Portrait backdrop measured 0/4 -> 4/4 plain on the failing character, no change on the one that already passed. After the portrait passes, the vision model describes hair, facial hair and eyes, and the turnaround and story prompts are rebuilt with it -- a character with no hair in his sheet got a different haircut on the sheet and failed the same-person check 3/3. Costume cut and colours restored for armed characters. v1.41.0. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
