Use one workspace for prompt-only generation and reference-based edits. The page decides between async generations and async edits automatically.
Reference uploads reuse the shared asset pipeline and are submitted to KIE as input_urls on the server.
Tasks are stored in the shared generation history, but this route filters them to GPT-Image-2.
Generated images are stored in the shared generation history and refreshed from KIE task status.
This list is filtered to GPT-Image-2 model-page image tasks only.
