+The CI workflow uses this remote mode after `main` deploys so e2e coverage validates the VPS deployment rather than the local runner host. It now generates a random per-run e2e key, temporarily appends it to the deployed `OPENBRAIN__AUTH__API_KEYS`, runs the suite, then removes the key and restarts the service.
+
+For live deployments, keep `OPENBRAIN__AUTH__API_KEYS` for persistent non-test access only. The server accepts a comma-separated key list, so a practical split is:
+
+- `prod_live_key` for normal agent traffic
+- `smoke_test_key` for ad hoc diagnostics
+
+In Gitea Actions, that means:
+
+- repo secret `OPENBRAIN__AUTH__API_KEYS=prod_live_key,smoke_test_key`
+
+If you want prod e2e coverage without leaving a standing CI key on the server, the workflow-generated ephemeral key handles that automatically.
