Find the conversation
In Chat, use the conversation history to select an earlier session. Review its messages and result cards before sending another task. New chat starts a separate conversation; it does not combine earlier chats or make their material available automatically.
Resume safely
Refresh to load saved messages and actual task states. If a task is still working, wait or cancel it before sending another generation request. Open a draft card to see its current revision; an older message is not proof that its old approval is still valid.
Reselect material needed for a new request. For a revision, use Revise in chat on the intended current draft. Do not expect a chat with a similar name or the same external author's name to share context.
Content that is no longer available
Deleted dependencies can block a draft and remove its body from previews. Raw text can also become unavailable under the applicable retention policy. History is not a permanent backup. Export needed data through Privacy and keep downloaded copies securely.
