 * cannot drift. Pass vitest's `describe`; `makeStore` returns a FRESH empty
 * store per call.
 *
 * Everything here goes through the public interface — never the tables — so a
 * backend is free to choose its own column types (sqlite keeps `metadata` as a
 * TEXT blob, Postgres as `jsonb`) as long as the observable behavior matches.
