Append master and worker_1..worker_8 IMAGE outputs after images/audio so each participant's own batch can be previewed. worker_N follows the Nth configured worker so a slot keeps its GPU when others are toggled; slots with no images return ExecutionBlocker(None) so attached nodes are skipped silently. The frontend labels worker_N with the worker's name. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
