+# Codex Phase 5 Prompt — Detection Pipeline Interface
+
+Implement the object detection pipeline interface without pretending that AI works when models are absent.
+
+## Goals
+
+- Detection service abstraction.
+- YOLO provider interface.
+- `not_configured` behavior when YOLO is disabled or model missing.
+- Test fixture provider for deterministic detection polygons in tests only.
+- Detection result persistence.
+- GeoJSON export of detections.
+
+## Requirements
+
+- Do not hardcode fake production detections.
+- Store confidence, class, geometry and model metadata.
+- Add API endpoint according to `docs/API_CONTRACTS.md`.
+- Add frontend state that shows configured/not configured.
+
+## Done when
+
+- Detection endpoint exists.
+- It returns `not_configured` by default unless explicitly enabled.
+- Tests can use fixture provider.
+- Persisted detections can be exported.
