//! Tool-approval choices and the per-phone pending-approval register.

//! While an approval is in flight, the next message from that phone (text or
//! button tap) is interpreted as a [`WaApproval`] instead of being routed to
//! the agent; `handler` resolves it through [`WhatsAppState::resolve_pending_approval`].
