Add real data detection QA workflow smoke

backend/README.md

@@ -352,6 +352,24 @@ Detection GeoJSON output. It does not download weights or inject detector
 fixtures. A zero detection result is still a valid runtime smoke outcome on the
 synthetic demo raster.
 
+To validate the configured building model on operator-provided GIS data, mount
+or copy a real georeferenced raster and a real reference-building GeoJSON onto
+the runtime host, then run:
+
+```bash
+REAL_RASTER_PATH=/mnt/user/appdata/geointel/data/orthophoto.tif \
+REAL_REFERENCE_VECTOR_PATH=/mnt/user/appdata/geointel/data/reference-buildings.geojson \
+bash scripts/verify_real_data_detection_qa_workflow.sh http://192.168.10.150:1202
+```
+
+This smoke refuses missing/unsupported inputs, uploads the raster and reference
+dataset through the normal dataset service, generates raster tiles, selects a
+local model asset, runs configured YOLO detection, compares persisted
+detections against persisted `vector_features`, persists QA/QC rows and exports
+the detection GeoJSON. It never seeds demo detections, enables fixture mode,
+fetches live providers or downloads model weights. Current V1 upload support is
+limited to GeoTIFF-style rasters and GeoJSON/JSON reference vectors.
