 # Changelog

+## Sprint 218 Regional terrain and flood completion (2026-07-16)
+
+- Provisioned and audited the complete governed Kempen matrices: 56 DHMV
+  DTM/DSM rasters and 336 VMM flood-scenario rasters across all 28 approved
+  municipalities, each with one DatasetVersion and a non-empty checksum-bound
+  GeoTIFF.
+- Bounded official WCS edge-grid rounding to at most 5%/0.25 m for DHMV and
+  VMM tile assembly, resampled accepted edge tiles to the exact 5 m analysis
+  grid and retained every source resolution and harmonized tile index in
+  provenance. Larger mismatches still fail closed.
+- Added exact regional raster-selection endpoints. They open only intersecting
+  persisted municipality partitions, mosaic the selected windows in memory
+  and calculate global cell statistics under the existing 12-million-cell
+  guard; no monolithic or hidden authoritative raster is created.
+- Updated the Map workspace to expose DHMV and VMM on the complete Kempen Area,
+  render all 28 matching MapLibre partitions, deduplicate VMM into twelve
+  scenario choices and analyse a drawn cross-boundary rectangle without first
+  selecting a municipality.
+- Preserved the distinction between DHMV height, modeled VMM scenario depth,
+  permanent water, bathymetry and concurrent flood volume.

 ## Sprint 217 Regional DOV soil coverage (2026-07-16)

 - Added a governed regional DOV soil operator for all 28 approved Kempen
