evaluate_hand
Versioned optimized immediate score from bengine-core. Played and held order is optimized, not evaluated literally. Unsupported effects are rejected.
recommend_action
Exact small-deck mathematical action values under optimal continuation in the supported model, not estimated real-game success. Returns all optimal ties and fully reconciled draw explanations; no recommendation on incomplete jobs. No A2/full-deck sampling.
compare_actions
Compare all immediate plays or exact small-deck play/discard values, with the same contract and validation as HTTP. Exact mode limits: 12 draw cards, two hands, two discards. Select explain_actions for particular branches.
get_solver_capabilities
Engine/rules/build identity, contract version, supported effects, assumptions and limits.
