/api/models reports `display_provider` when a catalog YAML sets one (`foundry`, `azure_foundry`, `cloudflare`), and the builder persists that string as a node's `llm_name`. The engine passed it straight to LLMCreator, which only knows the names in PROVIDERS_BY_NAME and raises `No LLM class found for type <label>`. That fails the node before any LLM call, so the turn ends in ~60ms with an empty answer and no tokens generated. It hits the *default* path: the platform-default model's label is stamped into every newly dragged agent node and validateWorkflow requires an agent node, so a new user's untouched workflow could not produce a token regardless of what they typed. Ordinary chat was unaffected because it resolves the provider from the model registry and never reads the stored name. Adds `resolve_dispatch_provider`, which prefers a stored name that is a real dispatch provider, then the registry lookup, then the parent agent. Nodes already saved with a label are repaired at run time, so no migration is needed. The api_key now resolves from the normalized name too — `get_api_key_for_provider` falls back to settings.API_KEY for names it does not recognize, which would have sent the deployment key to whatever endpoint the label happened to select.
