+## Governed annual agricultural-use parcels
+
+`scripts/provision_agricultural_parcel_history.py` uses the official annual
+download archives published by Agentschap Landbouw en Zeevisserij. Only the
+definitive editions 2008-2025 are allowed. The provisional current-campaign
+snapshot is deliberately excluded, and the retiring Digitaal Vlaanderen
+`Landbgebrperc` WFS is not used as the long-term source path.
+
+Each official ZIP, SHA256 checksum, full-edition crop code list and manifest is
+retained. The temporary GeoPackage is validated as EPSG:31370 with the stable
+annual field set, read through the GIS optional dependencies and deleted after
+the normalized GeoJSON has been built. Geometry is clipped exactly against the
+persisted scope Area in Lambert 72 and imported only through DatasetService.
+
+The regional default creates the series
+`alz:agricultural-use-parcels:kempen-transport-region`; `--scope mol` creates an
+independent Mol series. Selection and evolution expose exact intersected
+hectares for total declared use and official main-crop groups. Individual
+parcel additions/removals are unavailable because parcel identity is not
+stable across campaign years.
