What issue are you seeing?

In the Codex desktop app, archived child-agent threads in the sidebar can remain greyed out but still display the active spinner/loading indicator. Archiving them does not clear the spinning state, so the rows look both archived and still running at the same time.

This is happening with a cluster of child threads under the same parent thread. Some of the affected child IDs are already persisted under ~/.codex/archived_sessions/, but they still render as spinning in the desktop sidebar.

Confirmed affected archived child thread IDs:

• 019d5742-a58e-7082-937b-c37f04ae6329
• 019d5742-a66a-7f70-9ab5-ad870ce1eb5d
• 019d5742-a789-7342-b10f-f22f2154602c
• 019d59a8-62d1-7c61-9f03-890a99f4e4cc

Additional sibling child threads were visible in the same greyed/spinning cluster in the sidebar:

• 019d5c4c-178f-77d0-964f-8f2c144c3938
• 019d5c4c-189c-7342-b865-a39acf287039
• 019d5c52-8012-7093-af4b-583eb312c069

What steps can reproduce the bug?

1. Open a parent thread that has multiple spawned child-agent threads in the sidebar.
2. Let one or more child threads get into a stale/greyed-out state.
3. Archive those greyed child threads.
4. Observe the sidebar after archive.

The archived rows can continue to show the spinner/loading state instead of settling into a non-running archived state.

What is the expected behavior?

Once a child thread is archived, the sidebar should stop showing it as actively spinning. Archived rows should not continue to look like in-progress threads.
