+To validate the full configured-YOLO runtime path against Docker/Tower after a
+model is mounted and selected, run:
+
+```bash
+bash scripts/verify_model_asset_detection_workflow.sh http://192.168.10.150:1202

+
+The smoke uses the existing demo raster to generate a tile manifest, selects a
+cataloged local model asset, verifies read-only preflight, submits the existing
+detection run endpoint and checks persisted AnalysisRun, Detection list and
+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.
