 Mol is the primary operating context. On a fresh session the application opens the map-first geographic explorer, prefers the persisted `Mol Municipality Workbench`, selects the official NIS `13025` municipality boundary and activates the largest available authoritative building layer. Explicit project and dataset selections remain authoritative, and all broader Kempen workflows remain available.

+The map-first explorer has two deliberate modes. `Latest state` selects the
+latest explicitly dated source snapshot without claiming an old edition is
+current, while `Evolution` lets the operator compare an earlier and later
+snapshot from the same series over a drawn rectangle. Results show units,
+absolute/percentage change, estimate status and source limitations.
+Added/removed/modified overlays only appear for stable source identities.
+
+Selection results use dataset-specific PostGIS summaries. Object layers show
+intersecting counts, population shows inhabitants with partial-sector
+estimates clearly marked and land-cover sources show intersected hectares. The
+advanced workbench remains available but is not required for the primary
+choose-theme, draw-area, read-result flow.

 The primary workflow is deliberately short: choose a data theme, drag a rectangle on the MapLibre map and read the resulting PostGIS evidence. Releasing the drag runs the active theme query and every other available theme query for the same EPSG:4326 bbox. The result panel shows selection area, exact intersection totals, active-theme density, source identity and bounded feature properties. Map rendering remains capped at 1,000 features while `total_feature_count` reports the exact database count.

 The theme catalog currently recognizes buildings, population, forest/green, water, roads and parcels from dataset names and canonical `reference_layer_name` metadata. A theme is enabled only when a ready persisted vector dataset exists; otherwise it states `Bron nog niet ingeladen`. This prevents missing population or land-cover sources from appearing as zero-valued observations. The previous technical Map workspace remains available through `Geavanceerde werkbank` for derived datasets, QA/QC evidence and export operations.
