+## Architecture Analysis
+
+[Deply](https://github.com/Vashkatsi/deply) provides an optional baseline for this template's pragmatic Active Record-style architecture.
+It does not enforce Clean Architecture boundaries; the [verified recipe](https://vashkatsi.github.io/deply/doc/full-stack-fastapi-template.html) documents the scope and trade-offs.
+
+Run from the project root with the template's Python version:
+
+```bash
+uvx --from deply==1.0.0 --python 3.14 deply validate --config=deply.yaml
+uvx --from deply==1.0.0 --python 3.14 deply analyze --parallel --config=deply.yaml
+```
