+//! The Identity screen's model: who the library knows, and how the user fixes it.
+//!
+//! A third top-level screen beside the library and develop, because it is a
+//! *place you go to work*, not a panel you glance at: naming a cluster, pulling
+//! a stranger out of it, and merging two halves of the same person are tasks
+//! with their own rhythm, and they need the whole window.
+//!
+//! # The screen exists because the clustering is wrong
+//!
+//! That is not pessimism, it is FR-CULL-10: clustering will over-merge on
+//! siblings, on parents and children, and on the same person a decade apart. A
+//! tool that could only merge would make its own errors permanent, so
+//! **splitting is as prominent as merging here**, and every suggestion is
+//! visibly a suggestion until the user says otherwise.
+//!
+//! # What this module is, and is not
+//!
+//! It builds a view model from the catalog and applies the user's decisions
+//! back to it. It holds no Slint types, so the whole of it is testable against
+//! an in-memory catalog with no window open — which matters because the
+//! operations it performs are the ones that touch user data.
