+# activity-core llm-connect Service
+
+This overlay deploys `llm-connect` as an internal `activity-core` namespace
+service for daily WSJF triage.
+
+Stable in-cluster URL after apply:
+
+```text
+http://llm-connect.activity-core.svc.cluster.local:8080
+```
+
+Create provider credentials outside Git before applying the Deployment. For the
+default OpenRouter config:
+
+```bash
+kubectl -n activity-core create secret generic llm-connect-provider-secrets \
+  --from-literal=OPENROUTER_API_KEY="$OPENROUTER_API_KEY"
+```
+
+Apply:
+
+```bash
+docker build -t docker.io/library/llm-connect:latest .
+docker save docker.io/library/llm-connect:latest | ssh coulombcore sudo k3s ctr -n k8s.io images import -
+kubectl apply -k deploy/k8s/activity-core-llm-connect
+kubectl -n activity-core rollout status deployment/llm-connect
+```
+
+Smoke from inside the namespace, using an image that includes this repo's
+fixtures and `scripts/smoke_activity_core_endpoint.py`:
+
+```bash
+kubectl -n activity-core run llm-connect-smoke \
+  --rm -i --restart=Never \
+  --image=llm-connect:latest \
+  --env=LLM_CONNECT_URL=http://llm-connect.activity-core.svc.cluster.local:8080 \
+  --env=LLM_CONNECT_TIMEOUT_SECONDS=300 \
+  -- python scripts/smoke_activity_core_endpoint.py
+```
+
+Then set activity-core's runtime config:
+
+```text
+LLM_CONNECT_URL=http://llm-connect.activity-core.svc.cluster.local:8080
+LLM_CONNECT_TIMEOUT_SECONDS=300
+```
+
+Do not commit provider keys, live prompt payloads, or smoke response bodies that
+contain operational State Hub data.
