What's Wrong?

Yesterday a handful of sessions when I used the left arrow to see the bg agents, now I see a ton more. Claude confirmed:

- On disk, nothing changed about your sessions. ~/.claude/jobs/ still contains only the 5 jobs you dispatched Jul 7–8. No old session was converted into a background agent. - What changed is what the view displays. After last night's 00:28 auto-update to 2.1.204, the list now shows all 26 historical transcripts from ~/.claude/projects/ (across all 6 project dirs, oldest Jun 10 — your ~27-day-old entry) alongside the real background jobs. Since the changelog doesn't mention it, this is either an undocumented change or shipped behind a feature-flag rollout that happened to coincide with the update — the changelog gives no way to distinguish.

driving a bit too fast...

Only the 5 jobs should be listed
