Type Alias FinishReason

FinishReason:
    | { kind: "stop" }
    | { kind: "tool_calls" }
    | { kind: "max_tokens" }
    | { failure: LlmFailure; kind: "aborted" }
    | { failure: LlmFailure; kind: "error" }

Why a model response stopped.

error and aborted carry the failure facts, so an in-band provider error and a thrown one deliver the same LlmFailure to the same durable writer. Snake_case matches the spellings already in the session vocabulary (max_steps, tool_use).
