Codex Mac sidebar hides existing unpinned threads after update #29550

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.
