+## Sprint 201 Semantic area-selection metrics (2026-07-15)
+
+- Replaced count-only primary results for known regional themes with meaningful
+  PostGIS measurements: building footprint, forest, water and parcel area in
+  hectares; road and watercourse length in kilometres; and population in
+  inhabitants.
+- Kept intersecting feature counts as supporting evidence and added an additive
+  metric list without removing the existing primary summary fields.
+- Added explicit source limitations: building footprint is not floor area or
+  volume, road length is not traffic capacity and water volume is unavailable
