+"""backups plugin baseline (real create).
+
+Built after the ADR-008 ownership cutover, so unlike the ten cutover plugins
+whose 0001 is a stamp-only anchor, this baseline genuinely CREATES the table.
+The core chain never knew about backuprevisions, so this per-plugin chain is its
+sole authoritative creator.
+
+Emits explicit Alembic ops rather than using the create_plugin_tables helper:
+the helper builds a per-plugin MetaData filtered to the plugin's own tables, so
+the foreign key to the core assets table cannot resolve at CreateTable-compile
+time (NoReferencedTableError). Same shape autogenerate produces. Tables inherit
+the connection's default charset, matching how the core chain creates its own.
