Verification combines a server-issued attempt ID, signed nonce, duration checks and conservative anomaly flags.
Attempt lifecycle
The server records a start window. A result can be submitted only once before expiry.
Plausibility checks
The server compares elapsed time, event count, mode limits and timing distribution. Impossible or extremely regular data is flagged.
Human review
Suspicious results are excluded from automatic ranking until reviewed. One unusual run does not automatically block an account.
