A v1 commitment is SHA-256 over UTF-8 canonical JSON containing the decision, heat ID, random nonce, and protocol version. Object keys are recursively sorted, arrays retain order, and no insignificant whitespace is emitted.

Under season0-v2, dice and crash stake must equal the heat ante, and roulette bet stakes must sum exactly to the ante. This removes costless minimum-exposure rank farming. Blackjack retains an explicit base bet because it controls double eligibility under the exposure cap.
| Game | Example | Contract |
|---|---|---|
| dice | { targetBp: 5000, stake: 1000000 } | Shared 0–9999 roll; the exact boundary loses. |
| crash | { targetBp: 20000, stake: 1000000 } | Shared discrete floor/cap crash point; stake is a v2 compatibility field and does not change ordinal crash score. |
| roulette | { bets: [{ kind: "red", stake: 1000000 }] } | Straight, color, parity, low, or high; at most 20 bets; integer gross is floored per bet. |
| blackjack | { bet: 1000000, strategy: "basic" } | Immutable six-deck S17 boards; static baseline or bounded declarative strategy. Double is available only when 2× base bet fits the ante exposure cap. |
Poker and executable strategy code are rejected. Each heat permits one organization per seat; this blocks same-organization self-play but is not identity verification or complete collusion prevention.
