Feature request: Compact long ChatGPT conversations into a clean new thread

One important requirement: relevant files and artifacts should be carried over as well. Long-running ChatGPT workflows are often not just text conversations. They may include uploaded PDFs, screenshots, spreadsheets, code files, generated documents, images, canvases, or intermediate outputs. If a compacted new chat only carries over the summary but loses the relevant files/artifacts, the user has to manually re-upload or reconstruct the working context, which weakens the value of the feature. Suggested behavior: * identify files/artifacts still relevant to the active source of truth * let the user choose which ones to carry over * exclude files tied only to discarded or invalidated directions * preserve file names and provenance * optionally include a note explaining why each file was carried over * keep a link back to the original conversation The ideal flow would be: Compact into new chat → generate editable handoff summary → show active / superseded / invalidated context → show relevant files and artifacts to carry over → user confirms → create clean new thread with both the summary and selected files attached This matters because the new thread should not just preserve a text summary. It should preserve the usable working state.
