Rock-Paper-Scissors Arena

⚠️ 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

Best-of-three rock-paper-scissors against the house, played across multiple calls instead of a single stateless throw. Each Throw plays one round of your current match (starting a new one if you don't have one in progress); the house's move is derived deterministically from the current block height, a per-realm nonce, and your address. First to two round wins takes the match, and every player's match record (wins, losses, rounds played) is kept on-chain and viewable per-address.

Toolchain

Written against the sapphire (gno 0.9) stdlib split (chain, chain/runtime, gno.land/p/nt/avl/v0). The gno binary on PATH here is a newer/older mismatch of its own GNOROOT (native-function drift), so tests were run against a gno built from the exact pseudo-version pinned in that binary's own module info (github.com/gnolang/[email protected]). All 5 tests pass (gno test -v .) and gno lint . is clean.

What changed in v1

Identical behaviour to v0 apart from rendering, which now goes through p/moul/kit/ui instead of the local escapeInline helper.

Real escaping. The local helper replaced a handful of markdown metacharacters. ui.Inline and ui.Cell delegate to p/nt/markdown/sanitize, which also strips bidi and zero-width characters and folds newlines, so user text cannot reorder or escape the line it sits on.

The rendering change means the output differs from v0, which under this repo's versioning rule is a compatibility change, hence a new version rather than an edit in place. v0 stays live and untouched.
