 It supports exact preclipped municipality selection without changing the
 canonical `vector_features` schema or introducing operator-specific tables.

+## Bathymetry profile persistence
+
+VHA profile points require no new table or migration. The immutable GeoJSON
+artifact is stored as one normal reference `datasets` row and
+`dataset_versions` row; each exact point is a normal `vector_features` row with
+EPSG:4326 geometry and source properties. Existing dataset, source-feature and
+GiST indexes support selection.
+
+Profile measurement dates remain feature properties because a bounded Dataset
+can contain many historical campaigns. No artificial Dataset `observed_at` or
+temporal series is assigned. A future bed raster remains file/object storage
+plus Dataset metadata, not raster-in-database storage. Any national/maritime
+extension keeps source vertical datum, survey epoch and Area partition
+explicit and does not create a provider-specific shadow schema.
