Sessions not appearing in resume list despite valid session files

What's Wrong?

Valid session files are not appearing in the session picker/resume list. Sessions exist on disk with proper JSON structure but are missing from the UI list, making them impossible to resume without manually knowing the session ID.

What Should Happen?

All valid session files in ~/.claude/projects/<project>/ should appear in the session picker, sorted by recency.

Additional Information

Some sessions are missing from the list. In my case, a session from ~10 hours ago (Feb 4 at 8:52 PM) was not displayed, while sessions from 13+ hours ago were showing.

• Session file exists:

~/.claude/projects/.../f7488ea4-790b-4171-af40-f37ac48776d5.jsonl

• File is valid JSON (82 messages, last line parses correctly)
• No corrupted session files detected in the directory
• Session can be resumed manually with claude --resume f7488ea4-790b-4171-af40-f37ac48776d5
