EngineKind
The runtime strategy of a Session. Only cascaded is built for an Agent's engine; every other value is reserved there and refused with capability_not_available. From 1.56.0 the platform runs the evaluation Calls of evaluation suites and conversation tests on the minimal core of headless (model, Tools, Policies, no channel), and such a Call records engine: headless with purpose: evaluation; an Agent still never names it.
An enumeration of 5 values.
