-Check setup without downloading or rebuilding:
+Run the setup script with one explicit option:
+
+```bash
+bash data-setup/run_data_setup.sh <option>
+```
+
+Available options:
+
+- `--dry-run` — check setup scripts only.
+- `--download-only` — download script-accessible sources.
+- `--build-test` — rebuild model-ready inputs from existing local sources.
+- `--compare` — compare regenerated inputs with committed `data/` inputs.
+- `--full-test` — download, rebuild, and compare locally.
+
+Minimal check:
 
 ```bash
 bash data-setup/run_data_setup.sh --dry-run
 ```

 ```bash
 bash data-setup/run_data_setup.sh --download-only
