//! Mirror subsystem for the Control Plane.
//!
//! - [`registry`] — [`MirrorLinkRegistry`]: tracks active [`CrossClusterLink`]
//!   handles per database; used by `ALTER DATABASE PROMOTE` to tear down the
//!   source link before the catalog mutation lands.
//! - [`observer`] — lag-transition logic and the
//!   `nodedb_database_mirror_lag_ms` metric update path.
//! - [`restart`] — enumerates mirror databases on server start and
//!   returns the set that need their observer link re-established.
