Compare sessions (A vs B)

Goal

Compare two previously saved .emsession.json sessions and see per-event deltas (INVOKE/SUB) plus timing regression signals.

Steps

1. Open Window → Event Monitor.
2. Click 🆚 Compare… in the toolbar.
3. Select session A and then session B.
4. Review the Stats view:
   • events only in A (red),
   • events only in B (green),
   • timing regression highlight (orange).

Notes

• Compare mode is read-only.
• Comparison is computed from INVOKE/SUB rows captured in the sessions; subscriber state deltas are aggregated per event name.
• Use Back to live to return to the live EventBus timeline.
