+## 2026-07-19 - Complete bounded rectangle analysis
+
+Implemented:
+
+- removed the active-theme-only acquisition filter from Map rectangle
+  analysis;
+- added a deterministic acquisition queue capped at three concurrent official
+  provider requests;
+- restricted the result list to themes that are operational or have an
+  applicable bounded adapter in the resolved coverage zone;
+- replaced misleading `Bron ontbreekt` rows with explicit provider-failure
+  states and counts results per theme rather than per contributing layer;
+- registered VMM VHA historical profile points as an operational bounded
+  Flanders bathymetry source and connected its existing acquire/select routes
+  to the Map product catalogue.
+
+Live evidence:
+
+- a bounded Mol rectangle persisted and selected all relevant source families:
+  NGI, Statbel, four GRB products, seven Flemish thematic rasters, DHMV,
+  VMM flood hazard, BWK/Natura 2000, DOV soil and VHA profile points;
+- semantic results included building/forest/agricultural/open-space/water/
+  parcel/soil/nature hectares, road kilometres, inhabitants, terrain height,
+  flood area, accessibility/service scores and historical profile counts;
+- no browser-direct provider request, fabricated value or vertical-datum
+  conversion was introduced.
+
+Validation:
+
+- the complete readiness gate passed: 1,053 backend tests, 24 frontend tests,
+  backend compile, frontend TypeScript/typecheck, production build, Alembic
+  head `202607160001` and script smoke checks;
+- a live API smoke over `5.10,51.17,5.11,51.18` proved all 17 applicable Mol
+  themes through acquisition or persisted national data and semantic
+  selection metrics;
+- browser verification follows against the deployed commit on port 1202.
