	// on the next request for the provider to accept the turn. Depending on
	// provider and role this is a signature (Anthropic thinking MAC, Gemini
	// thoughtSignature) or a ciphertext blob (Anthropic redacted_thinking
	// data, OpenAI reasoning.encrypted_content). Callers shouldn't inspect
	// or construct it — just round-trip the value from Response.Turn.
