## Overview

The repository combines a browser racing game with a distributed leaderboard backend, plus a separate Python client/server simulation path. The main interactive flow is game play and score updates through the Socket.IO gateway, which routes updates to Python server nodes and relays leaderboard results. The README documents hashing-based distribution; server.ts shows the routing and failover behavior. Frontend event handlers are partially sampled, so UI event wiring is represented only at the documented Socket.IO boundary.

Main entry points: [`distributed_server.py`](https://github.com/shreelakshmigbhat/velocitytorquenationv3/blob/main/distributed_server.py) (Server Nodes), [`server.ts`](https://github.com/shreelakshmigbhat/velocitytorquenationv3/blob/main/server.ts) (Socket.IO Gateway), [`src/App.tsx`](https://github.com/shreelakshmigbhat/velocitytorquenationv3/blob/main/src/App.tsx) (Racing Game), [`distributed_client.py`](https://github.com/shreelakshmigbhat/velocitytorquenationv3/blob/main/distributed_client.py) (Python Game Client)
