The decision API ecosystem the call conforms to, i.e. which request and
response shape the client speaks, as identified by the client or server:
"typesafe" for the TypeSafe System One / Jev API, "openai" for the OpenAI
Decisions API. A self-hosted vLLM server answering the Jev-compatible
/v1/systemone shape is still "typesafe". Distinct from DECISION_PROVIDER,
which says who hosts the model. Well-known values are DecisionSystem,
which alias the matching LLMSystem values.
