Right column, capture/fixtures/agents/dmr.yaml: agents.root with model qwen resolves to models.qwen with provider runner, which resolves to providers.runner with provider dmr and base_url http://localhost:12434/engines/llama.cpp/v1. Bottom row: the auto decision as doctor printed it. No cloud provider has a credential, so auto looks for a pulled Model Runner model: with the runner up it picks dmr/docker.io/ai/qwen3:4b, and with no runner it names dmr/ai/qwen3:latest and reports no usable model.',
