 # Changelog

+## Sprint 216 Regional thematic coverage (2026-07-16)
+
+- Provisioned all five governed Departement Omgeving thematic rasters for all
+  28 approved Kempen municipalities and for the complete persisted transport
+  region. The resulting 145 ready Datasets remain linked to exact Areas and
+  contain no duplicate area/product pairs.
+- Raised only the thematic-raster acquisition envelope to the measured Kempen
+  extent: 60 km per side and 30 million output pixels. Official WCS reads stay
+  partitioned into fixed 10 km tiles; orthophoto, DHMV and flood limits were not
+  changed.
+- Added bounded retries for interrupted or transient official WCS tile
+  responses. Partial bytes are never accepted and three failed attempts still
+  produce the canonical provider-unavailable error.
+- Hardened the local assistant prompt so year, source and measurement quality
+  must remain attached to the same Dataset when one requested theme has
+  multiple official observations.
+- Verified the complete regional map workflow against live PostGIS. A full
+  Kempen selection reports 45,126.87 ha space occupation, 97,375.81 ha open
+  space, an estimated 484,146.70 inhabitants from the 2019 density raster and
+  the persisted 2022 accessibility and service scores.
+- No migration, live provider integration, synthetic metric or direct database
+  write was introduced.
