 **Env file writes**: the PATCH endpoint updates `model_assignments.json` and attempts to rewrite the service's `.env` file in-place. Because host paths (e.g. `/opt/stacks/karakeep/.env`) are not bind-mounted into the gateway container, `env_written` will be `false` — apply manually and `docker compose up -d --force-recreate <service>`.
 
+**Nextcloud assistant** uses `integration_openai` app pointing at `https://ai.nuclide.systems/v1` (LiteLLM). No env file — config is in the Nextcloud DB, changed via `occ`:
+```bash
+# On CT 105 (192.168.1.41):
+docker exec nextcloud-aio-nextcloud php occ config:app:set integration_openai default_completion_model_id --value=<model>
+# Clear stale model cache after changes:
+docker exec nextcloud-aio-nextcloud php occ config:app:delete integration_openai models
+```
