turnframe-runtime 0.1.2

//! A stage with nothing to say is not asked to speak.
//!
//! The acknowledgement is requested only when the turn has material of its own: a
//! receipt, a refusal, a notice, or something outstanding on a case it engaged.
//! The runtime knows there is none before the call, so it does not make the call.
