• #25332

Summary

After updating to the latest Codex Desktop version, the conversations that were previously lost because of the large-paste/attached-document title-generation bug have not been automatically restored to the sidebar or accessible conversation history.

The original bug pattern was:

1. The user pastes a large prompt/document into Codex Desktop.
2. Codex converts it into an attached document, such as Pasted text.txt.
3. If the user does not type additional text into the message box, the conversation may fail to get a normal generated summary title.
4. The conversation remains in a fallback/failed title state such as New chat / New content.
5. Later, the conversation can disappear from the visible sidebar/history and become unreachable from the UI.

The latest update may have changed some behavior going forward, but it did not restore the conversations that were already affected.

Current behavior after update

After updating to 26.601.20914, my previously lost conversations are still missing. They did not reappear in the project sidebar, the general history list, or any visible recovery location.

I have multiple Codex conversations that became unreachable because of this bug. Updating the app did not recover them.

Expected behavior

Codex should not only fix the bug for future conversations. It also needs a recovery/migration path for users who already lost access to affected conversations.

At minimum, a new version should attempt to:

• re-index local/backend conversations that failed title generation,
• restore attachment-only prompt conversations to the sidebar/history,
• show a stable fallback title such as Untitled chat, New chat, timestamp-based title, or thread ID,
• expose a recovery page or diagnostic tool for orphaned/unlisted conversations,
• make conversations discoverable even if title generation failed.

Actual behavior

The previously affected conversations remain inaccessible after the latest update. The user still has no obvious UI path to find or resume those lost threads.

Why this is urgent

This is a serious recoverability issue. Codex conversations often contain development history, debugging context, implementation decisions, and completed work. If a title-generation/indexing bug causes finished conversations to disappear from the UI, users may lose access to important project context.

Fixing only the future behavior is not enough. Users who already encountered the bug need a way to recover their missing conversations. Otherwise, the historical work remains effectively lost.

Request

Please prioritize a recovery/reindex mechanism for conversations affected by the attachment-only paste / failed-title / disappearing-history bug. Existing affected conversations should be restored to the sidebar/history automatically where possible, or Codex should provide a user-facing recovery tool to locate and reopen them.
