Codex Mac sidebar hides existing unpinned threads after update

Summary

After updating Codex Desktop for Mac, recent existing threads are not visible in the sidebar unless pinned. The threads still exist: internal thread lookup can find/read them, and pinning makes them appear.

Environment

• Product: Codex Desktop for Mac
• Current version: 0.142.0
• Affected thread was created before the update
• Host: local macOS

Observed behavior

• A recent all-day thread was missing from the sidebar.
• Internal thread listing could still find it.
• Reading the thread by internal id worked.
• Pinning the thread made it appear in the sidebar.
• Unpinned visibility appears broken or filtered after the update.

Expected behavior

Recent local threads should appear in the sidebar without requiring pinning. If a project/worktree filter is active, it should be visible and searchable recovery should still work.

Suspected area

Sidebar thread index/filter hydration after update, possibly related to project/worktree scoping or older thread metadata migration.
