All 4 additional test runs failed identically with persistent stale
queue entry (pane_id %22 vs test pane %0). This is a critical test
isolation issue - the queue clearing logic is not fully effective.
Run 2-5: ~34s duration, pane_id mismatch failure
Baseline run 1: 35s duration, unknown failure
Recommendations:
- Stronger test isolation needed
- Consider database truncation instead of queue skipping
- Investigate source of persistent pane %22 entry
