A task's pictures no longer in the output folder are marked gone when the task is read and shown as "Picture deleted" (timeline, results strip, stage panels and picks) instead of a broken picture; "@" no longer offers them. The AI hears plainly that the user deleted one, and a tool reading a gone picture says it may have been deleted. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
