 - Results are generated from persisted PostGIS `vector_features`, not from client-side map data.
 - `feature_count` is the number of GeoJSON features returned in the bounded preview. `total_feature_count` is the exact number of persisted rows intersecting the requested bbox or persisted Area geometry.
 - `summary` keeps one backwards-compatible primary metric and exposes all relevant measurements in `metrics`. Known themes use metric PostGIS calculations: building/forest/water/parcel surfaces in hectares, road and watercourse lengths in kilometres, population in inhabitants and intersecting feature counts as supporting evidence.
+- Governed datasets may declare additional `source_metadata.selection_metrics`.

 - Area and length calculations transform geometry to Belgian Lambert 72 (`EPSG:31370`); they are never calculated in geographic degrees.
 - Water volume is not inferred from 2D GRB geometry. It remains unavailable until a source provides reliable depth or bathymetry with compatible spatial coverage and provenance.
 - The response is capped by `limit` and returns `truncated=true` when `total_feature_count` exceeds the returned preview.

 Supported PostGIS aggregations are feature count, intersection area,
 intersection length, numeric sum and area-weighted numeric sum. Area and length
 are measured after transformation to EPSG:31370.
