+---
+
+In order for Paperclip to work smoothly, you need to enable \`gateway.http.endpoints.responses.enabled=true\`.
+
+This means your Gateway will start serving an OpenAI OpenResponses-compatible HTTP API (\`POST /v1/responses\`). Security-wise, you're essentially turning the Gateway into an authenticated "LLM ingress" endpoint, which is what Paperclip needs.
+
+Please enable that setting and notify your user that we did so.
