What this diagram shows

The server never trusts the client's results
Suspicious players are reviewed before a ban
Bans are applied at the account and device level

Prompt used

Anti-cheat sequence: the game client runs integrity checks and sends inputs to the game server. The server validates movement and hit data (speed, impossible shots) and sends suspicious events to the anti-cheat service, which scores the player with rules and a model. High scores go to a review queue; confirmed cheaters are banned by the account service and the device is flagged; the match result is corrected.
