Problem:
After forking a Codex conversation into a new worktree, the forked thread does not appear in the default sidebar project-sorted view. It appears only after switching sidebar sorting to chronological order.

Expected:
Forked worktree threads should remain visible under the original project, or be shown clearly as a worktree child thread.

Actual:
The thread appears hidden/missing in project-sorted sidebar, making it look like the forked conversation was lost.

Environment:
Windows 11
Codex Desktop App
Original project path: D:\codexProjects\worktree_test
Worktree path: C:\Users\Xiao\.codex\worktrees\2103\worktree_test

Steps to reproduce:

1. Open Codex Desktop App on Windows.
2. Open a saved project backed by a Git repository, for example:

D:\codexProjects\worktree_test

1. Keep the sidebar organization set to:

Organize sidebar -> Sort by -> By project

1. Start a conversation in that project.
2. From the conversation, choose to fork/derive the conversation into a new worktree.
3. Wait until worktree creation completes.
4. Continue chatting in the forked worktree conversation.
5. Click the original conversation in the left sidebar, or inspect the project-sorted sidebar.
6. The forked conversation appears to be missing from the sidebar.
7. Change sidebar sorting to:

Organize sidebar -> Sort by -> Chronological order

1. The forked conversation appears again.

Actual result:
The forked worktree conversation is hidden or not discoverable in the default project-sorted sidebar view. It looks like the forked conversation was lost.

Expected result:
A conversation forked into a new worktree should remain visible in the sidebar under the original project, or under a clear worktree child/group entry. It should not disappear from the default project-sorted view.

Notes:
The Git worktree itself is created successfully. The issue appears to be only with sidebar grouping/indexing.

Original project path:
D:\codexProjects\worktree_test

Forked worktree path:
C:\Users\Xiao\.codex\worktrees\2103\worktree_test

Observed Git state:
The forked conversation cwd was:
C:\Users\Xiao\.codex\worktrees\2103\worktree_test

The worktree existed and was listed by git worktree list.

Possible cause:
The project-sorted sidebar may be grouping conversations by physical cwd/project path. Since the forked worktree cwd is under:
C:\Users\Xiao\.codex\worktrees\...
instead of the original saved project path:
D:\codexProjects\worktree_test
the forked thread may not be associated with the original project group.

Code / commands used to create the minimal repo:

mkdir D:\codexProjects\worktree_test
cd D:\codexProjects\worktree_test
New-Item simple1.txt -ItemType File
git init -b main
git add .
git commit -m "Initial commit"
