//! Record merge models.
//!
//! When two events are confirmed duplicates, one survives (the *main*
//! record) and the other is soft-deleted. A [`MergeRequest`] drives the
//! operation, a [`MergeResponse`] reports the result, and a
//! [`MergeRecord`] is persisted as an audit-able history entry holding a
//! snapshot of the transferred data. See `agents/share/merge.md` for
//! the workflow.
