+  national total of 11,825,551 inhabitants (11,817,897 spatially located plus
+  7,654 explicitly unlocated).
+- Live bounded PICC and UrbIS persistence proved the same service path:
+  54 Walloon building geometries retained in Dataset
+  `0c3c0a11-c00e-4c84-87be-8ffa64302dec` and 47 Brussels building geometries
+  in Dataset `de53ccc0-a494-4c4e-bd0d-16d807bfefe7`.
+- Corrected the map catalog precedence so reusable persisted datasets win over
+  on-demand placeholders. National Statbel 2025 population is now presented
+  as the active source, while selection-bounded PICC/UrbIS acquisitions remain
+  available only through an exact bounded request.
 - Focused backend and frontend suites passed before full release validation;
   full local and Tower evidence follows in the final P5 gate.
