+## 2026-07-22 - National scope and governed Brussels land cover
+
+Implemented:
+
+- made the persisted Belgium/North Sea project the unconditional startup
+  workspace and changed the initial basemap extent and form defaults from Mol
+  to Belgium plus its legally labelled maritime scope;
+- retained Mol/Kempen provisioning and tests strictly as golden regression
+  evidence instead of product routing;
+- live-validated the UrbIS WFS `Blocks` contract and added bounded land-cover,
+  FO/GB forest/park and WB permanent-water products with clipped PostGIS area
+  metrics and source-class provenance;
+- restricted the production model picker to the explicit active model asset
+  and surfaced that the current building model is locally, not nationally,
+  validated.
+
+Validated during implementation:
+
+- backend compile and frontend typecheck passed;
+- 31 frontend unit tests passed;
+- focused national coverage, model catalog, project lifecycle and Mol golden
+  regression tests passed;
+- live resolver checks covered Brussels, Wallonia and all three Belgian
+  maritime legal zones. WALOUS, Walloon flood analytics and multi-epoch marine
+  bathymetry remain real open source-integration work and were not simulated.
+- the final repository readiness gate passed with 1,084 backend tests, 31
+  frontend unit tests, compile, typecheck, production build, Alembic head
+  `202607160001` and all script syntax/contract checks.
