What's Wrong?

Bug Description

After updating Claude Code to v2.1.100, all conversations from today
disappeared from the UI. Restarting the app did not restore them.

Key finding: data is NOT lost

JSONL files are still on disk with today's timestamps — this is a UI
display bug, not data loss.

Steps to reproduce

1. Use Claude Code, accumulate conversations during the day
2. Update to v2.1.100
3. Reopen — all today's conversations gone from sidebar

• OS: macOS 14 (Sonoma)
• Platform: Desktop app
• Date: 2026-04-14

Workaround

None. Reboot and window reload don't help.
