+### Mol operational validation pack
+
+The operator registry includes a Mol-first validation pack: Mol center,
+Achterbos residential, Gompel mixed settlement, Donk canal/industrial and
+Postel rural village. The four new zones are marked as validation holdouts so
+future training exports cannot silently consume the operational benchmark.
+Postel-bos is evaluated separately as a background control.
+
+`run_mol_operational_validation.sh` composes the existing positive multi-sample
+quality matrix and background detection matrix. Positive runs use persisted GRB
+`vector_features` and create real `QualityCheck`/`Metric` rows; background runs
+only report persisted detection pressure and never synthesize QA metrics. AOI
+bounds from the operator manifest are persisted as EPSG:4326 `Area` records so
+every generated project opens as a complete map context.
