+> **Nx state in Docker:** the containers keep their Nx cache and project
+> graph in a dedicated `dev-nx` Docker volume, isolated from the host's
+> `.nx/` directory. This prevents the Linux/Alpine containers and your
+> host (e.g. macOS) from sharing — and corrupting — the same Nx store. To
+> reset only the containers' Nx state, run:

+> ```shell
+> docker volume ls -q --filter name='dev-nx$' | xargs docker volume rm -f
+> ```

+> For a full reset (including the database), use `docker compose down -v`.
