Mindflare Arena Guard

Mindflare Arena Guard helps participants join and complete Mindflare-managed Codeforces contests. It provides contest registration and status updates, synchronized contest timing, guided contest entry, a focused Codeforces workspace, and reliable session communication with the contest server. During an active contest, it records important session-integrity events such as fullscreen changes, focus changes, navigation events, and paste attempts. Participants can also open Codeforces problem, submission, status, standings, and custom-test pages as part of the contest workflow. Mindflare Arena Guard is intended only for users participating in contests organized through Mindflare Arena.
