Windows Desktop: Project Timeline shows no history despite existing threads (path identity mismatch with OneDrive/GoodSync/junction/\\?\ prefix)

What version of the Codex App are you using (From “About Codex” dialog)?

26.415.20818

What subscription do you have?

Pro

What platform is your computer?

Microsoft Windows NT 10.0.26200.0 x64

What issue are you seeing?

Project Timeline in Codex Desktop shows no history, even though thread/session history exists on disk.

What steps can reproduce the bug?

1. Use Codex Desktop on Windows with workspace under OneDrive-backed path.
2. Open project via C:\Users\jacob\GoodSync\repos\net_80_migration (junction form).
3. After restarts/path normalization attempts, Timeline becomes empty.
4. Data still exists:

• ~/.codex/sessions/**/rollout-*.jsonl contains session_meta entries.
• ~/.codex/state_5.sqlite contains threads rows.

What is the expected behavior?

Timeline should show existing thread history for the project regardless of equivalent Windows path forms.

Additional information

What do you see instead?

Timeline is empty. Internally, path identity drifts across:

• C:\Users\jacob\GoodSync\...
• C:\Users\jacob\OneDrive\GoodSync\...
• \\?\C:\Users\jacob\OneDrive\GoodSync\...

Additional information

Evidence from local inspection before restore:

• session_meta_entries: 32
• threads_total: 32
• session_meta cwd mostly C:\Users\jacob\GoodSync\repos\...
• DB threads.cwd mostly \\?\C:\Users\jacob\OneDrive\GoodSync\repos\...
• C:\Users\jacob\GoodSync is a junction targetting C:\Users\jacob\OneDrive\GoodSync

This looks like a Windows path canonicalization/path-equivalence bug in project timeline matching.
