+## Sprint 216 Regional thematic coverage (2026-07-16)
+
+Changed:
+- Ran the governed thematic-raster operator for every one of the 28 persisted
+  municipality Areas in `Kempen Regional Workbench` after a successful
+  Arendonk smoke. All five allowlisted products completed for every Area.
+- Added five separately persisted snapshots for the complete `Vervoerregio
+  Kempen - officiele operationele grens`, enabling free selections that cross
+  municipality boundaries while preserving exact Area clipping.
+- Increased only `THEMATIC_RASTER_MAX_SIDE_M` to 60,000 and
+  `THEMATIC_RASTER_MAX_PIXELS` to 30,000,000. The service still rejects larger
+  requests and reads the official WCS in fixed 10 km tiles.
+- Retried transient WCS failures at most three times with a bounded delay.
+  Interrupted responses are discarded and permanent failures remain explicit.
+- Required the local assistant to keep each metric's year, source and
+  measurement quality together when a theme has several official datasets.
+
+Validation evidence:
+- The final inventory contains 145 ready thematic Datasets across 29 Areas and
+  five product keys, with zero missing metadata/storage paths and zero duplicate
+  Area/product pairs. All 145 TIFF files are non-empty and occupy 56 MB.
+- A second complete-region operator run reused all five existing Datasets.
+- Browser validation on `http://192.168.10.150:1202` showed every regional
+  thematic source as available, rendered the MapLibre overlay and calculated
+  the complete Kempen result without browser warnings or errors.
+- The full readiness gate passed 733 backend tests, compilation, fixture and
+  API-contract audits, one Alembic head, frontend typecheck, production build
+  and shell checks.
+- Live PostGIS reports version 3.6 and the all-in-one container remained
+  healthy throughout acquisition and analysis.
+
+Next:
+- Generalize the separate DOV soil-map operator from Mol to all 28 municipality
+  partitions. Keep the historical 1949-1971 survey semantics and raw source
+  manifest explicit; do not merge soil provenance into the raster operator.
