 # Changelog
 
+## Sprint 217 Regional DOV soil coverage (2026-07-16)
+
+- Added a governed regional DOV soil operator for all 28 approved Kempen
+  municipalities. It validates the official scope artifact, clips in Lambert
+  72, retains deterministic gzip WFS responses and imports through the existing
+  DatasetService/vector-feature flow.
+- Added NIS-suffixed persisted feature ids for source polygons split by
+  municipality boundaries, while retaining the original DOV source id in
+  provenance properties.
+- Persisted one complete regional snapshot with 27,200 valid soil polygons
+  assembled from 62 source responses and 46,134 bounded source features.
+- Kept the 1949-1971 survey period, 1:20,000 scale and historical drainage
+  limitation visible in map results and assistant context.
+- Disabled preclipped metric shortcuts for the regional snapshot. Exact
+  PostGIS intersections remain mandatory because CRS round trips can create
+  negligible coordinate-rounding slivers at administrative boundaries.
+- No migration, new endpoint, direct database write or current-soil claim was
+  introduced.

+The regional operator retains one checksummed WFS evidence chain per
+municipality, gives boundary-split source features a NIS suffix and assembles
+one Dataset linked to the complete Kempen Area. EPSG:31370 clipping followed by
+EPSG:4326 persistence can create submeter coordinate-rounding slivers at the
+stored boundary, so regional and municipal selection metrics deliberately run
+the exact PostGIS intersection instead of using a preclipped fast path.
+
 Use `--fetch-only` to retain and validate source evidence without importing.
 The operator never writes directly to PostGIS. Soil drainage and related map
 classes represent the 1949-1971 survey and are not current observations.

+## Sprint 217 Regional DOV soil coverage (2026-07-16)
+
+Changed:
+- Generalized the explicit DOV `bodemkaart:bodemtypes` operator from Mol to the
+  approved 28-member Kempen scope without changing source or persistence
+  semantics.
+- Added independently reusable municipality partitions, deterministic gzip raw
+  responses, boundary/output checksums, unique NIS-suffixed persisted ids and
+  one regional snapshot manifest.
+- Packaged and release-checked the operator in the all-in-one image.
+- Kept regional and municipality metric queries on exact PostGIS intersections
+  instead of asserting a preclipped fast path across CRS round trips.
+
+Validation evidence:
+- The live operator completed 28/28 partitions, 62 WFS responses, 46,134
+  bounded source features and 27,200 persisted valid EPSG:4326 polygons.
+- PostGIS found zero invalid/empty/wrong-SRID geometries, zero duplicate source
+  ids, complete municipality/NIS identity and 139,871.44 ha mapped area.
+- A strict storage-boundary audit measured only 355.15 m2 of coordinate-rounding
+  slivers across 579 boundary features (about 0.000025%); exact selection
+  intersections prevent those slivers from bypassing the selected Area.
+- A repeat operator run reused every verified partition and the existing
+  Dataset.
+- Browser validation showed Bodem available for the complete Kempen and for
+  Arendonk, returned 139,871.44 ha and 5,514.99 ha respectively, rendered the
+  MapLibre layer at detail zoom and produced no browser warnings or errors.
+- The pre-deployment readiness gate passed 738 backend tests, compilation,
+  contract checks, one Alembic head, frontend typecheck and production build.
+
+Next:
+- Fill the remaining region-wide current-state gaps shown in the Map workspace:
+  VMM flood-hazard coverage and DHMV terrain. Preserve their separate modeled
+  scenario and elevation semantics; do not infer current water volume.
