1//! Loro-backed storage does not use SQL schema migrations.
 2//!
 3//! The old SQLite migration flow has been replaced by document-level metadata
 4//! (`meta.schema_version`) in the Loro snapshot. This module remains only as a
 5//! compatibility shim for call sites that still invoke migration entry points.
