      The Agents plugin still stores a service or bot that differs from the
      deployed gateway contract ({{ MATTERMOST_LITELLM_BASE_URL }},
      model {{ LITELLM_CHAT_MODEL }}), so prompts would leave the deployment,
      use a model the gateway does not serve, or carry a stale virtual key.
      An empty model means the gateway serves none: neither svc-ai-ollama nor
      svc-ai-lmstudio is in this deployment and no remote provider key is set.

      The Agents plugin never created the '{{ MATTERMOST_LITELLM_BOT_NAME }}'
      bot account, so no Mattermost surface can address the gateway. The merged
      config row alone does not provision the account; only the plugin's
      EnsureBots run on activation does.
