+Live validation:
+- Tower was redeployed at commit `2d0e02e`; the all-in-one container became
+  healthy on port 1202, PostGIS 3.6 answered, Alembic remained at the single
+  `202607160001` head and the frontend/API proxy smoke passed.
+- A read-only PostGIS edition audit found real official-ID changes between 14
+  and 15 July: buildings 46 added/32 removed, roads 22/13, water 4/6 and
+  parcels 27/27 across the region.
+- Four bounded canonical API comparisons returned
+  `object_changes.available=true` and persisted GeoJSON evidence for every GRB
+  theme. The checked selections returned 8 building, 20 road, 4 water and 20
+  parcel changes respectively.
+- The live browser exposes `Bebouwing · GRB (14-15 jul 2026)`, both exact
+  observation dates and the registration-versus-physical-change warning. The
+  workbench remained visually coherent and produced no browser warnings or
+  errors.

 Next:
-- Redeploy the legacy-contract correction, verify a real bounded GRB edition
-  delta through the canonical API and inspect the daily Evolution UI on Tower.
+- Evaluate ALZ as the next governed edition probe only after its official
+  machine-readable release version and schema stability are verified.
