+Actual note: Batch 3 moved API ownership to transitional `BlogContentModule`, `WordpressMirrorModule`, and `AssetModule` boundaries while retaining legacy business internals behind imported modules for compatibility. Contract tests now parse `sql/refactor-v3/00-full-schema.sql` through `test/helpers/sql-schema.helper.ts` so domain expectations catch SQL schema drift instead of only repeating local constants. Route compatibility and duplicate-controller safety are covered by module graph tests, with `QqbotModule` mocked in metadata-only specs to avoid unrelated BangDream/NapCat side effects.
