Yes
data class Yes(val query: String, val bindings: List<BindingPresentation> = emptyList(), val solvedQuery: String? = null, val metadata: Map<String, String> = emptyMap()) : SolutionPresentation
The goal succeeded; solvedQuery/bindings are pre-formatted, and metadata carries any extension's per-solution extras (e.g. PLP's probability), keyed by a well-known string name.
