+## Sprint 210 - Regional BWK/Natura 2000 expansion (2026-07-16)
+
+Implemented:
+- Added `provision_regional_bwk_natura2000.py` for the approved 28-municipality
+  Kempen transport-region scope, using the existing official INBO state-2025
+  source contract and governed Mol feature normalization.
+- Added per-municipality WFS pagination, exact EPSG:31370 clipping,
+  municipality-suffixed feature identities, deterministic gzip retention of
+  every exact source response and checksum-bound partition/snapshot reuse.
+- Kept one canonical regional Dataset upload behind DatasetService. No direct
+  `vector_features` write, migration, endpoint or fabricated time series was
+  introduced.
+- Made map theme selection prefer an exact selected-Area Dataset over a broader
+  compatible regional Dataset. Updated the source inventory to present
+  overlapping BWK snapshots as area coverages without double-counting their
+  feature totals.
+- Added focused tests for source evidence, GIS clipping, context fields,
+  regional assembly, semantic metrics, upload metadata, packaging and UI
+  selection behavior.
+
+Validation so far:
+- Focused BWK suites pass 11 tests.
+- Full local readiness passes backend compilation, 689 backend tests, API
+  contract audit, one Alembic head (`202607150001`), frontend typecheck/build
+  and script syntax gates.
+
+Open for this pass:
+- Deploy the validated operator to Tower, fetch and persist all 28 official
+  partitions, verify idempotency and PostGIS row/geometry/checksum consistency,
+  then validate complete-region and Mol map/metric behavior in the browser.
