 Managed together via shell scripts in `scripts/`.
 
+## Canonical Offline Release
+
+All future Linux AMD64 offline releases must use
+`deploy/linux-docker-offline-deerflow-only/build-release.sh`.  This is the
+repository's canonical DeerFlow-only deployment path; do not package the
+historical DeerFlow + WeKnora deployment variant.  The canonical bundle uses
+`config/deploy.env` as its only hand-edited configuration source and includes
+the `aiomysql` database adapter, persistent `source/wheelhouse` extension
+support, multi-model configuration, and the Office document runtime.
+
+Follow `docs/DeerFlow纯离线标准发版与部署.md` for source synchronization,
+building, verification, installation, source-only updates, rollback, and
+artifact retention.
