Repair the Live Collaboration Board

Fix optimistic updates and reconnect logic in a real-time board client

Overview

A live collaboration board mostly works until real traffic hits it. Cards get duplicated, stale snapshots overwrite fresh local work, and reconnects can lose optimistic moves.

Your job is to repair the client-side state reconciliation logic.

What makes this hard

  • The board mixes local optimistic ops with server snapshots
  • Temporary client IDs must reconcile cleanly to real server IDs
  • Reconnect flow must preserve pending local intent without duplicating cards
  • Hidden tests replay state transitions in different orders

Gradient scoring is based on the percentage of tests passed.
