Interface ExplorationState

Immutable exploration-state snapshot. Reducers return a new object on change; readers compare by reference (prev.filters !== next.filters).

Fields map 1:1 to the slices that views can subscribe to (see ExplorationSlice). Adding a field requires extending the slice union, the reducer's diff logic, and the linked-view preset table.

interface ExplorationState {
    aggregation?: AggregationSpec;
    extent?: HonuaExtent;
    filters: Readonly<Record<string, FilterClause>>;
    grouping: readonly string[];
    page: PaginationSpec;
    preset: LinkedViewPresetName;
    selection: readonly FeatureSelectionTarget[];
    sort: readonly SortSpec[];
    spatialFilter?: SpatialFilter;
    visibleFields: readonly string[];
}
