+# CI workflows (placeholder)
+
+Not yet functional — filled in during Phase 6. Deployment is GitOps via the
+team's existing ArgoCD instance (see `infra/argocd/` and
+`docs/adr/0002-argocd-gitops.md`) — CI never runs `kubectl`/`helm` against a
+cluster directly. Planned workflows:
+
+- `ai-service-ci.yml` — lint/test/build/push image for `apps/ai-service`
+- `node-services-ci.yml` — lint/test/build for the NestJS services
+- `web-ci.yml` — lint/test/build for `apps/web`
+- `ingestion-ci.yml` — lint/test for the `ingestion` pipeline
+- `bump-image-tag.yml` — on image push, updates the image tag in the
+  relevant `infra/helm/medical-chatbot/values-<env>.yaml` and commits/pushes
+  that change; ArgoCD picks it up from there
