Rapid-Fire Mutations

Ten mutations fire simultaneously via Promise.all. Each triggers an SSE invalidation event. This demos that the system handles rapid concurrent events without dropping updates or causing race conditions.

What to watch for

  • Click 'Add 10 todos rapidly' — all fire in parallel
  • The event counter increments as each SSE event arrives
  • Final count should always match: baseline + 10
  • No race conditions — the last SSE event wins and the list is always consistent
