What's Wrong?

When archiving a Code session in Claude Desktop (Windows), the session disappears from the active session list but does NOT appear when selecting the "Archived" filter in the left sidebar.

The isArchived flag is correctly set to true in the session JSON file under AppData/Roaming/Claude/claude-code-sessions/, confirming that the archive action itself works. However, the Archive filter UI does not display archived Code sessions — they become completely inaccessible from the UI.

The only workaround is to manually edit the session JSON file and change "isArchived":true to "isArchived":false.

What Should Happen?

Archived Code sessions should be visible when selecting the "Archived" filter in the left sidebar, just like regular Chat sessions. Users should be able to view and unarchive Code sessions from the Archive filter.

Additional Information

This bug occurs specifically with Code sessions in Claude Desktop (Windows). The archive action correctly sets "isArchived": true in the session JSON file located at:

%AppData%\Claude\claude-code-sessions\{org-id}\{user-id}\local_{session-id}.json

However, the "Archived" filter in the left sidebar does not query or display these archived Code sessions. The workaround is to manually edit the JSON file and set "isArchived": false to restore the session.

This issue is specific to Code sessions — it is unclear if regular Chat sessions have the same problem.
