VS Code Codex conversation missing from sidebar but resumable by session ID in CLI

Start by reproducing the missing conversation with session ID 019fb023-24b8-7881-9119-509f078b610e and compare the VS Code conversation panel with the JSONL session under C:\Users\ACCER.codex\sessions\2026\07\30. Use codex resume to confirm the session remains valid; done when a valid local session remains visible and accessible in the extension sidebar.

What issue are you seeing?

A Codex conversation disappeared from the conversation history/sidebar in the Codex VS Code extension even though I did not delete or archive it.

The conversation still exists locally as a JSONL session and can be resumed successfully using the Codex CLI.

Session ID:
019fb023-24b8-7881-9119-509f078b610e

Local session folder:
C:\Users\ACCER.codex\sessions\2026\07\30

Resume command:
codex resume 019fb023-24b8-7881-9119-509f078b610e

The complete conversation opens correctly in the terminal Codex interface. However, it does not appear in the Codex conversation panel inside Visual Studio Code.

The conversation disappeared after my Codex usage reached 0%. When my usage reset and I returned to VS Code, the conversation was no longer visible. I do not know whether the usage reset is related, but the local session was not deleted.

What is the expected behavior?

A valid local Codex conversation that still exists on disk and can be resumed by the Codex CLI should remain visible and accessible in the Codex VS Code extension conversation panel.

The extension should also provide a way to re-index or restore local sessions that disappear from the sidebar.

Additional information

I already tried:

• Reloading the VS Code window
• Restarting Visual Studio Code
• Opening the original project folder
• Checking chronological conversation history
• Checking archived conversations
• Confirming that I am using the same ChatGPT account
• Resuming the session through the Codex CLI

The CLI successfully restores the full conversation, so the transcript does not appear to be corrupted or deleted.
