 ---
 
-Check out the configuration reference at https://huggingface.co/docs/hub/spaces-config-reference
+# Phase 1 only — not the production DefectRAG migration
+
+This isolated proof preserves the existing React dashboard. Only one public VisA
+PCB1 fixture is accepted for real DINOv2 scoring and heatmap generation.
+Use **Image inspection**, choose **PCB 1**, select the **PCB 1 anomalous sample**,
+then **Run inspection**. Alternatively upload the same supplied JPEG file.
+
+No arbitrary private images are accepted. History here is temporary test data.
+RAG/batch execution and cloud staff collaboration are not migrated or enabled.
+The normal local application and its configured Supabase workspace remain intact.
+Some local-runtime labels remain historical UI text; this test runs in the Space.
+
+The test uses frozen DINOv2 ViT-S/14, its existing normal-reference bank and
+unchanged operational threshold. No training or new accuracy evaluation occurs.
+The Space requires configured ZeroGPU hardware; a CPU-only run is not proof of
+ZeroGPU compatibility. Inspect the returned phase1 and device metadata.
