AI/Infra: Develop an anomaly detection system for cheating behavior

[chinweobtagaz]

Description

To maintain platform integrity in rated pools, we must identify and ban users who are using engines to assist their play.

What Needs to be Done

• Develop an offline cron job that analyzes recent rated games.
• Compare player moves against Stockfish top-choice correlation.
• Analyze move-time variance (e.g., taking exactly 3 seconds for every move).
• Flag accounts exceeding the confidence threshold for human review.

Acceptance Criteria

• System accurately flags accounts with >90% engine correlation.
• Does not auto-ban, but populates a dashboard for admins.
• Lightweight enough to run nightly over thousands of games.
