+## Cross-domain thematic rasters and DOV soil
+
+The governed thematic registry exposes five fixed MercatorNet products through
+`GET .../datasets/thematic-raster/products`. Acquisition uses
+`POST .../datasets/thematic-raster/acquire`; selection and PNG rendering use
+`POST .../raster/thematic/select` and `GET .../raster/thematic/image`.
+
+Provision every product for the exact persisted Mol Area:
+
+```bash
+docker exec geointel python /app/scripts/provision_thematic_rasters.py
+```
+
+Inspect the complete 28-municipality matrix without writes, then run it after
+the Mol source/runtime gate passes:
+
+```bash
+docker exec geointel python /app/scripts/provision_thematic_rasters.py \
+  --project-name "Kempen Regional Workbench" --all-municipalities --dry-run
+```

+`THEMATIC_RASTER_MAX_PIXELS`, `THEMATIC_RASTER_TIMEOUT_SECONDS` and
+`THEMATIC_RASTER_MAX_RESPONSE_MB`.
+
+Provision the official DOV soil polygons for Mol through the existing vector
+upload path:
+
+```bash
+docker exec geointel python /app/scripts/provision_mol_soil_map.py
+```
+
+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.

 Run the explicit operator after the regional workspace and Mol Area exist:
