+## Starter Template (BINDING for new repos)
+
+**[chittyseed-fractal](https://github.com/chittyfoundation/chittyseed-fractal)** — every new ChittyApps repo MUST start from this template. Click "Use this template" on the GitHub repo page, or run:
+
+```bash
+gh repo create chittyapps/<your-app> --template chittyfoundation/chittyseed-fractal --public
+```
+
+The template encodes the fractal trinity layout (identity / authority / connectivity), provides the standard `scope.json` manifest, CHARTER/CHITTY/CLAUDE templates, package.json with `validate:fractal` + `certify` scripts, and a CI workflow that gates merges on fractal-layout compliance.
+
+Validation contract: `chittycanon://core/services/chittyschema#meta/fractal-layout`
