Changelog

Next feature release

• [Feature]: Externalised the card library: cards load from allowlisted JSON sets in mundane-cards, validated against a vendored schema and snapshotted with a content hash into each game (mundane.api.set_loader). POST /games takes an optional set_urls body; the export now includes the card snapshot.

• [Feature]: A thin Litestar HTTP API (mundane.api) to create games, read state, submit moves (rejected moves become HTTP 422), and export the action log.

• [Feature]: The Mundane rules engine — mundane.engine.rules.apply_action() as the single state-transition function, an event-sourced mundane.engine.game.Game log, and a fully JSON-serialisable mundane.engine.state.GameState that stores cards by id.
