What's Wrong?

Sessions from the previous 1–2 days don't appear in the /resume picker for a project, even though
several other older/newer sessions for the same project do appear.

I manually inspected the underlying transcript files for the missing sessions and ruled out data
loss/corruption:

• The JSONL files exist and are fully valid JSON (no truncation).
• They are correctly scoped to the project's cwd.
• They are not marked as sidechains.
• No separate session index explains a stale list — ~/.claude.json only tracks a single

lastSessionId, not a full session list, so the picker appears to read the transcript directory
directly.

This looks like a display/ordering bug in the /resume picker rather than data loss, since
resuming directly by session ID works fine.

What Should Happen?

All valid, non-sidechain sessions for the current project should appear in the /resume picker,
regardless of how many days ago they occurred.

Error Messages/Logs

None — no error is shown, the sessions are just silently absent from the list.

Steps to Reproduce

1. Work in a project across several days, accumulating multiple session transcripts under

~/.claude/projects/<project>/.

1. Let some time pass with additional newer sessions created in the same project.
2. Run /resume inside Claude Code in that project.
3. Observe that some sessions from 1–2 days prior are missing from the list, despite their

transcript files being present, valid, and correctly scoped to the project.
Workaround: claude --resume <session-id> (session ID taken from the transcript filename) resumes
the missing session correctly.
