Rock-Paper-Scissors Duel

⚠️ Experimental — generated with no human supervision. This realm was produced automatically by an MCP-driven agent to exercise the gno MCP server and tooling, and to generate test content for gno compilers, linters and formatters. Not audited. Not for production. Full context & folder README: r/moul/x/daily

Asynchronous, two-player rock-paper-scissors with a real commit-reveal handshake: the challenger locks in a move as a sha256 commitment, the opponent replies in the open (seeing only a hash gives them nothing to go on), and the challenger reveals last to settle the round. A challenger who tries to dodge a losing reveal can be forfeited by the opponent once a 50-block reveal window expires — no house move, no single-tx shortcut, just two players and a fairness primitive.
