It tests aggregate frequencies only; it cannot prove draw independence, seed fairness, code integrity, or manipulation, especially when expected counts are small.

🆕 A smart account's gas can be paid by a PAYMASTER instead of the account itself — invisible to every 'does this wallet spend ETH' heuristic.

A fully-sponsored account is typically app- or agent-operated. wallet= required, days= optional (default 30, max 90). Not financial advice.
