+## Bathymetry profile vector contract
+
+The operational VHA layer is an EPSG:4326 point FeatureCollection. Required
+normalized properties are:
+
+- `provider_record_id` and `source_feature_id`;
+- `watercourse_vhag`, `watercourse_name` and alternative names;
+- `profile_number` and `measurement_date`;
+- nullable `recorded_depth_m`, `recorded_crown_width_m` and
+  `recorded_floor_width_m`;
+- nullable allowlisted `source_document_url`;
+- `document_available`, `structured_depth_available`;
+- `measurement_semantics=historical_cross_section_profile_point`;
+- `vertical_reference=document-specific`.
+
+Null means the provider did not expose a structured value. It is never
+converted to zero. Dataset metadata records exact counts, measurement range,
+scope, attribution and `volume_supported=false`.
