package connect4_v2 is a staked Connect 4 game. A creator posts an offer with a ugnot stake; anyone (or a named opponent) accepts with the same stake; the winner takes the pot minus a flat house fee.
The first mover is picked by commit-reveal: the creator offers with sha256(passphrase) and must Reveal the passphrase within 90s of Accept, or forfeit. Randomness computed in Accept could be re-rolled by an acceptor who bundles [Accept, Play] in one atomic tx and lets it revert.
Every move has a 90s clock measured in block time. Nothing on-chain fires by itself, so an expired clock is settled by anyone calling ClaimTimeout: an unrevealed game is won by the acceptor, a game whose first mover never moved is void and both stakes are refunded, otherwise the player who ran out of time forfeits.
ActiveJSON returns {"now":<unix>,"games":[...]}: Open and Playing games in id order, skipping offset and returning at most limit (clamped to 1-100).
