 - Added explicit operator provisioners for official Statbel Mol population snapshots (2021-2025) and Digitaal Vlaanderen historical land-use snapshots (1778, 1873 and 1969); no source is fetched during application startup.
 - Preserved methodological honesty: partial statistical sectors are labelled area-weighted estimates, historical land-use identity changes are not fabricated and all source URLs, versions and processing limitations are persisted.
 - Serialized Tower startup and migration-smoke validation by waiting for container health, preventing concurrent Alembic upgrades from racing on the same PostGIS schema.
+- Normalized valid source Z coordinates to the canonical 2D PostGIS vector store while retaining the original uploaded GeoJSON and reporting the source Z-feature count in metadata.
+- Made vector dataset, version and feature persistence one transaction, with file cleanup on rollback, so an indexing error cannot leave a ready dataset without persisted features.
