Definition
Ollaya, Lichen, verdict, and Rizzo Flow are used by changing the base URL. System One Connector does the same for agents and can set TYPESAFE_MODEL when the local server is CLM. The request body (state, model name, and the question map) stays in the System One shape.
A swap still changes answers. Option limits, Noul-only servers, uncalibrated confidence, and a server that ignores API keys are all compatible at the JSON layer and different in behavior. Log the model field that comes back, not the alias you sent.
