+## 2026-07-21 - Persisted raster scale guard
+
+Live verification of the first scale-aware release showed that on-demand
+provider fan-out was resolved, but already persisted 5 m terrain and flood
+rasters could still enter a Belgium-scale analysis. The shared selection guard
+now applies the same real pixel budgets to persisted rasters: country-scale
+overview analysis keeps PostGIS vector and national statistical sources, while
+high-resolution rasters require detail or safely bounded regional extent.
+
+Validation:
+
+- frontend typecheck, 29 unit tests and the production build passed;
+- the map acquisition, component-boundary and density regression contracts
+  passed (12 tests);
+- live redeployment and a repeated Belgium-scale rectangle follow on the
+  immutable patch revision.
