+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.
